+KernelVersion:	2.6.12-rc2 (predates git)
+Contact:	selinux@vger.kernel.org
+Description:
+
+	The selinuxfs "checkreqprot" node allows SELinux to be configured
+	to check the protection requested by userspace for mmap/mprotect
+	calls instead of the actual protection applied by the kernel.
+	This was a compatibility mechanism for legacy userspace and
+	for the READ_IMPLIES_EXEC personality flag.  However, if set to
+	1, it weakens security by allowing mappings to be made executable
+	without authorization by policy.  The default value of checkreqprot
+	at boot was changed starting in Linux v4.4 to 0 (i.e. check the
+	actual protection), and Android and Linux distributions have been
+	explicitly writing a "0" to /sys/fs/selinux/checkreqprot during
+	initialization for some time.  Support for setting checkreqprot to 1
+	will be	removed in a future kernel release, at which point the kernel
+	will always cease using checkreqprot internally and will always
+	check the actual protections being applied upon mmap/mprotect calls.
+	The checkreqprot selinuxfs node will remain for backward compatibility
+	but will discard writes of the "0" value and will reject writes of the
+	"1" value when this mechanism is removed.

+Boot Interrupts

+
+Overview
+========
+
+On PCI Express, interrupts are represented with either MSI or inbound
+interrupt messages (Assert_INTx/Deassert_INTx). The integrated IO-APIC in a
+given Core IO converts the legacy interrupt messages from PCI Express to
+MSI interrupts.  If the IO-APIC is disabled (via the mask bits in the
+IO-APIC table entries), the messages are routed to the legacy PCH. This
+in-band interrupt mechanism was traditionally necessary for systems that
+did not support the IO-APIC and for boot. Intel in the past has used the
+term "boot interrupts" to describe this mechanism. Further, the PCI Express
+protocol describes this in-band legacy wire-interrupt INTx mechanism for
+I/O devices to signal PCI-style level interrupts. The subsequent paragraphs
+describe problems with the Core IO handling of INTx message routing to the
+PCH and mitigation within BIOS and the OS.

+When in-band legacy INTx messages are forwarded to the PCH, they in turn
+trigger a new interrupt for which the OS likely lacks a handler. When an
+interrupt goes unhandled over time, they are tracked by the Linux kernel as
+Spurious Interrupts. The IRQ will be disabled by the Linux kernel after it
+reaches a specific count with the error "nobody cared". This disabled IRQ
+now prevents valid usage by an existing interrupt which may happen to share
+the IRQ line.

+
+Conditions
+==========
+
+The use of threaded interrupts is the most likely condition to trigger
+this problem today. Threaded interrupts may not be reenabled after the IRQ
+handler wakes. These "one shot" conditions mean that the threaded interrupt
+needs to keep the interrupt line masked until the threaded handler has run.
+Especially when dealing with high data rate interrupts, the thread needs to
+run to completion; otherwise some handlers will end up in stack overflows
+since the interrupt of the issuing device is still active.
+
+Affected Chipsets
+=================
+
+The legacy interrupt forwarding mechanism exists today in a number of
+devices including but not limited to chipsets from AMD/ATI, Broadcom, and
+Intel. Changes made through the mitigations below have been applied to
+drivers/pci/quirks.c
+
+Starting with ICX there are no longer any IO-APICs in the Core IO's
+devices.  IO-APIC is only in the PCH.  Devices connected to the Core IO's
+PCIe Root Ports will use native MSI/MSI-X mechanisms.
+
+Mitigations
+===========
+
+The mitigations take the form of PCI quirks. The preference has been to
+first identify and make use of a means to disable the routing to the PCH.
+In such a case a quirk to disable boot interrupt generation can be
+added.[1]
+
+  Intel® 6300ESB I/O Controller Hub
+  Alternate Base Address Register:
+   BIE: Boot Interrupt Enable
+	  0 = Boot interrupt is enabled.
+	  1 = Boot interrupt is disabled.
+
+  Intel® Sandy Bridge through Sky Lake based Xeon servers:
+  Coherent Interface Protocol Interrupt Control
+   dis_intx_route2pch/dis_intx_route2ich/dis_intx_route2dmi2:
+	  When this bit is set. Local INTx messages received from the
+	  Intel® Quick Data DMA/PCI Express ports are not routed to legacy
+	  PCH - they are either converted into MSI via the integrated IO-APIC
+	  (if the IO-APIC mask bit is clear in the appropriate entries)
+	  or cause no further action (when mask bit is set)
+
+In the absence of a way to directly disable the routing, another approach
+has been to make use of PCI Interrupt pin to INTx routing tables for
+purposes of redirecting the interrupt handler to the rerouted interrupt
+line by default.  Therefore, on chipsets where this INTx routing cannot be
+disabled, the Linux kernel will reroute the valid interrupt to its legacy
+interrupt. This redirection of the handler will prevent the occurrence of
+the spurious interrupt detection which would ordinarily disable the IRQ
+line due to excessive unhandled counts.[2]
+
+The config option X86_REROUTE_FOR_BROKEN_BOOT_IRQS exists to enable (or
+disable) the redirection of the interrupt handler to the PCH interrupt
+line. The option can be overridden by either pci=ioapicreroute or
+pci=noioapicreroute.[3]
+
+
+More Documentation
+==================
+
+There is an overview of the legacy interrupt handling in several datasheets
+(6300ESB and 6700PXH below). While largely the same, it provides insight
+into the evolution of its handling with chipsets.

 =============================================
 
 One of the best applications of RCU is to protect read-mostly linked lists
-("struct list_head" in list.h).  One big advantage of this approach
+(``struct list_head`` in list.h).  One big advantage of this approach
 is that all of the required memory barriers are included for you in
 the list macros.  This document describes several applications of RCU,
 with the best fits first.
 
-Example 1: Read-Side Action Taken Outside of Lock, No In-Place Updates
+
+Example 1: Read-mostly list: Deferred Destruction
+-------------------------------------------------
+
+A widely used usecase for RCU lists in the kernel is lockless iteration over
+all processes in the system. ``task_struct::tasks`` represents the list node that
+links all the processes. The list can be traversed in parallel to any list
+additions or removals.
+
+The traversal of the list is done using ``for_each_process()`` which is defined
+by the 2 macros::
+
+	#define next_task(p) \
+		list_entry_rcu((p)->tasks.next, struct task_struct, tasks)
+
+	#define for_each_process(p) \
+		for (p = &init_task ; (p = next_task(p)) != &init_task ; )
+
+The code traversing the list of all processes typically looks like::
+
+	rcu_read_lock();
+	for_each_process(p) {
+		/* Do something with p */
+	}
+	rcu_read_unlock();
+
+The simplified code for removing a process from a task list is::
+
+	void release_task(struct task_struct *p)
+	{
+		write_lock(&tasklist_lock);
+		list_del_rcu(&p->tasks);
+		write_unlock(&tasklist_lock);
+		call_rcu(&p->rcu, delayed_put_task_struct);
+	}
+
+When a process exits, ``release_task()`` calls ``list_del_rcu(&p->tasks)`` under
+``tasklist_lock`` writer lock protection, to remove the task from the list of
+all tasks. The ``tasklist_lock`` prevents concurrent list additions/removals
+from corrupting the list. Readers using ``for_each_process()`` are not protected
+with the ``tasklist_lock``. To prevent readers from noticing changes in the list
+pointers, the ``task_struct`` object is freed only after one or more grace
+periods elapse (with the help of call_rcu()). This deferring of destruction
+ensures that any readers traversing the list will see valid ``p->tasks.next``
+pointers and deletion/freeing can happen in parallel with traversal of the list.
+This pattern is also called an **existence lock**, since RCU pins the object in
+memory until all existing readers finish.

+
+Example 5: Skipping Stale Objects
+---------------------------------
+
+For some usecases, reader performance can be improved by skipping stale objects
+during read-side list traversal if the object in concern is pending destruction
+after one or more grace periods. One such example can be found in the timerfd
+subsystem. When a ``CLOCK_REALTIME`` clock is reprogrammed - for example due to
+setting of the system time, then all programmed timerfds that depend on this
+clock get triggered and processes waiting on them to expire are woken up in
+advance of their scheduled expiry. To facilitate this, all such timers are added
+to an RCU-managed ``cancel_list`` when they are setup in
+``timerfd_setup_cancel()``::
+
+	static void timerfd_setup_cancel(struct timerfd_ctx *ctx, int flags)
+	{
+		spin_lock(&ctx->cancel_lock);
+		if ((ctx->clockid == CLOCK_REALTIME &&
+		    (flags & TFD_TIMER_ABSTIME) && (flags & TFD_TIMER_CANCEL_ON_SET)) {
+			if (!ctx->might_cancel) {
+				ctx->might_cancel = true;
+				spin_lock(&cancel_lock);
+				list_add_rcu(&ctx->clist, &cancel_list);
+				spin_unlock(&cancel_lock);
+			}
+		}
+		spin_unlock(&ctx->cancel_lock);
+	}
+
+When a timerfd is freed (fd is closed), then the ``might_cancel`` flag of the
+timerfd object is cleared, the object removed from the ``cancel_list`` and
+destroyed::
+
+	int timerfd_release(struct inode *inode, struct file *file)
+	{
+		struct timerfd_ctx *ctx = file->private_data;
+
+		spin_lock(&ctx->cancel_lock);
+		if (ctx->might_cancel) {
+			ctx->might_cancel = false;
+			spin_lock(&cancel_lock);
+			list_del_rcu(&ctx->clist);
+			spin_unlock(&cancel_lock);
+		}
+		spin_unlock(&ctx->cancel_lock);
+
+		hrtimer_cancel(&ctx->t.tmr);
+		kfree_rcu(ctx, rcu);
+		return 0;
+	}
+
+If the ``CLOCK_REALTIME`` clock is set, for example by a time server, the
+hrtimer framework calls ``timerfd_clock_was_set()`` which walks the
+``cancel_list`` and wakes up processes waiting on the timerfd. While iterating
+the ``cancel_list``, the ``might_cancel`` flag is consulted to skip stale
+objects::
+
+	void timerfd_clock_was_set(void)
+	{
+		struct timerfd_ctx *ctx;
+		unsigned long flags;
+
+		rcu_read_lock();
+		list_for_each_entry_rcu(ctx, &cancel_list, clist) {
+			if (!ctx->might_cancel)
+				continue;
+			spin_lock_irqsave(&ctx->wqh.lock, flags);
+			if (ctx->moffs != ktime_mono_to_real(0)) {
+				ctx->moffs = KTIME_MAX;
+				ctx->ticks++;
+				wake_up_locked_poll(&ctx->wqh, EPOLLIN);
+			}
+			spin_unlock_irqrestore(&ctx->wqh.lock, flags);
+		}
+		rcu_read_unlock();
+	}
+
+The key point here is, because RCU-traversal of the ``cancel_list`` happens
+while objects are being added and removed to the list, sometimes the traversal
+can step on an object that has been removed from the list. In this example, it
+is seen that it is better to skip such objects using a flag.

+
+USAGE ON MAINLINE KERNELS
+
+When using rcutorture to test changes to RCU itself, it is often
+necessary to build a number of kernels in order to test that change
+across a broad range of combinations of the relevant Kconfig options
+and of the relevant kernel boot parameters.  In this situation, use
+of modprobe and rmmod can be quite time-consuming and error-prone.
+
+Therefore, the tools/testing/selftests/rcutorture/bin/kvm.sh
+script is available for mainline testing for x86, arm64, and
+powerpc.  By default, it will run the series of tests specified by
+tools/testing/selftests/rcutorture/configs/rcu/CFLIST, with each test
+running for 30 minutes within a guest OS using a minimal userspace
+supplied by an automatically generated initrd.  After the tests are
+complete, the resulting build products and console output are analyzed
+for errors and the results of the runs are summarized.
+
+On larger systems, rcutorture testing can be accelerated by passing the
+--cpus argument to kvm.sh.  For example, on a 64-CPU system, "--cpus 43"
+would use up to 43 CPUs to run tests concurrently, which as of v5.4 would
+complete all the scenarios in two batches, reducing the time to complete
+from about eight hours to about one hour (not counting the time to build
+the sixteen kernels).  The "--dryrun sched" argument will not run tests,
+but rather tell you how the tests would be scheduled into batches.  This
+can be useful when working out how many CPUs to specify in the --cpus
+argument.
+
+Not all changes require that all scenarios be run.  For example, a change
+to Tree SRCU might run only the SRCU-N and SRCU-P scenarios using the
+--configs argument to kvm.sh as follows:  "--configs 'SRCU-N SRCU-P'".
+Large systems can run multiple copies of of the full set of scenarios,
+for example, a system with 448 hardware threads can run five instances
+of the full set concurrently.  To make this happen:
+
+	kvm.sh --cpus 448 --configs '5*CFLIST'
+
+Alternatively, such a system can run 56 concurrent instances of a single
+eight-CPU scenario:
+
+	kvm.sh --cpus 448 --configs '56*TREE04'
+
+Or 28 concurrent instances of each of two eight-CPU scenarios:
+
+	kvm.sh --cpus 448 --configs '28*TREE03 28*TREE04'
+
+Of course, each concurrent instance will use memory, which can be
+limited using the --memory argument, which defaults to 512M.  Small
+values for memory may require disabling the callback-flooding tests
+using the --bootargs parameter discussed below.
+
+Sometimes additional debugging is useful, and in such cases the --kconfig
+parameter to kvm.sh may be used, for example, "--kconfig 'CONFIG_KASAN=y'".
+
+Kernel boot arguments can also be supplied, for example, to control
+rcutorture's module parameters.  For example, to test a change to RCU's
+CPU stall-warning code, use "--bootargs 'rcutorture.stall_cpu=30'".
+This will of course result in the scripting reporting a failure, namely
+the resuling RCU CPU stall warning.  As noted above, reducing memory may
+require disabling rcutorture's callback-flooding tests:
+
+	kvm.sh --cpus 448 --configs '56*TREE04' --memory 128M \
+		--bootargs 'rcutorture.fwd_progress=0'
+
+Sometimes all that is needed is a full set of kernel builds.  This is
+what the --buildonly argument does.
+
+Finally, the --trust-make argument allows each kernel build to reuse what
+it can from the previous kernel build.
+
+There are additional more arcane arguments that are documented in the
+source code of the kvm.sh script.
+
+If a run contains failures, the number of buildtime and runtime failures
+is listed at the end of the kvm.sh output, which you really should redirect
+to a file.  The build products and console output of each run is kept in
+tools/testing/selftests/rcutorture/res in timestamped directories.  A
+given directory can be supplied to kvm-find-errors.sh in order to have
+it cycle you through summaries of errors and full error logs.  For example:
+
+	tools/testing/selftests/rcutorture/bin/kvm-find-errors.sh \
+		tools/testing/selftests/rcutorture/res/2020.01.20-15.54.23
+
+However, it is often more convenient to access the files directly.
+Files pertaining to all scenarios in a run reside in the top-level
+directory (2020.01.20-15.54.23 in the example above), while per-scenario
+files reside in a subdirectory named after the scenario (for example,
+"TREE04").  If a given scenario ran more than once (as in "--configs
+'56*TREE04'" above), the directories corresponding to the second and
+subsequent runs of that scenario include a sequence number, for example,
+"TREE04.2", "TREE04.3", and so on.
+
+The most frequently used file in the top-level directory is testid.txt.
+If the test ran in a git repository, then this file contains the commit
+that was tested and any uncommitted changes in diff format.
+
+The most frequently used files in each per-scenario-run directory are:
+
+.config: This file contains the Kconfig options.
+
+Make.out: This contains build output for a specific scenario.
+
+console.log: This contains the console output for a specific scenario.
+	This file may be examined once the kernel has booted, but
+	it might not exist if the build failed.
+
+vmlinux: This contains the kernel, which can be useful with tools like
+	objdump and gdb.
+
+A number of additional files are available, but are less frequently used.
+Many are intended for debugging of rcutorture itself or of its scripting.
+
+As of v5.4, a successful run with the default set of scenarios produces
+the following summary at the end of the run on a 12-CPU system:

+hugetlb.<hugepagesize>.usage_in_bytes
+hugetlb.<hugepagesize>.failcnt
+
+The HugeTLB controller allows users to limit the HugeTLB usage (page fault) per
+control group and enforces the limit during page fault. Since HugeTLB
+doesn't support page reclaim, enforcing the limit at page fault time implies
+that, the application will get SIGBUS signal if it tries to fault in HugeTLB
+pages beyond its limit. Therefore the application needs to know exactly how many
+HugeTLB pages it uses before hand, and the sysadmin needs to make sure that
+there are enough available on the machine for all the users to avoid processes
+getting SIGBUS.
+
+
+2. Reservation accounting
+
+hugetlb.<hugepagesize>.rsvd.limit_in_bytes
+hugetlb.<hugepagesize>.rsvd.max_usage_in_bytes
+hugetlb.<hugepagesize>.rsvd.usage_in_bytes
+hugetlb.<hugepagesize>.rsvd.failcnt
+
+The HugeTLB controller allows to limit the HugeTLB reservations per control
+group and enforces the controller limit at reservation time and at the fault of
+HugeTLB memory for which no reservation exists. Since reservation limits are
+enforced at reservation time (on mmap or shget), reservation limits never causes
+the application to get SIGBUS signal if the memory was reserved before hand. For
+MAP_NORESERVE allocations, the reservation limit behaves the same as the fault
+limit, enforcing memory usage at fault time and causing the application to
+receive a SIGBUS if it's crossing its limit.
+
+Reservation limits are superior to page fault limits described above, since
+reservation limits are enforced at reservation time (on mmap or shget), and
+never causes the application to get SIGBUS signal if the memory was reserved
+before hand. This allows for easier fallback to alternatives such as
+non-HugeTLB memory for example. In the case of page fault accounting, it's very
+hard to avoid processes getting SIGBUS since the sysadmin needs precisely know
+the HugeTLB usage of all the tasks in the system and make sure there is enough
+pages to satisfy all requests. Avoiding tasks getting SIGBUS on overcommited
+systems is practically impossible with page fault accounting.
+
+
+3. Caveats with shared memory
+
+For shared HugeTLB memory, both HugeTLB reservation and page faults are charged
+to the first task that causes the memory to be reserved or faulted, and all
+subsequent uses of this reserved or faulted memory is done without charging.
+
+Shared HugeTLB memory is only uncharged when it is unreserved or deallocated.
+This is usually when the HugeTLB file is deleted, and not when the task that
+caused the reservation or fault has exited.
+
+
+4. Caveats with HugeTLB cgroup offline.
+
+When a HugeTLB cgroup goes offline with some reservations or faults still
+charged to it, the behavior is as follows:
+
+- The fault charges are charged to the parent HugeTLB cgroup (reparented),
+- the reservation charges remain on the offline HugeTLB cgroup.
+
+This means that if a HugeTLB cgroup gets offlined while there is still HugeTLB
+reservations charged to it, that cgroup persists as a zombie until all HugeTLB
+reservations are uncharged. HugeTLB reservations behave in this manner to match
+the memory controller whose cgroups also persist as zombie until all charged
+memory is uncharged. Also, the tracking of HugeTLB reservations is a bit more
+complex compared to the tracking of HugeTLB faults, so it is significantly
+harder to reparent reservations at offline time.

+allows you to do the bookkeeping about the write in the uffd reading
+thread before the ioctl.
+
+If you registered with both UFFDIO_REGISTER_MODE_MISSING and

+
+AMD PowerNow! Drivers
+=====================
+
+::
+
+ PowerNow! and Cool'n'Quiet are AMD names for frequency
+ management capabilities in AMD processors. As the hardware
+ implementation changes in new generations of the processors,
+ there is a different cpu-freq driver for each generation.
+
+ Note that the driver's will not load on the "wrong" hardware,
+ so it is safe to try each driver in turn when in doubt as to
+ which is the correct driver.
+
+ Note that the functionality to change frequency (and voltage)
+ is not available in all processors. The drivers will refuse
+ to load on processors without this capability. The capability
+ is detected with the cpuid instruction.
+
+ The drivers use BIOS supplied tables to obtain frequency and
+ voltage information appropriate for a particular platform.
+ Frequency transitions will be unavailable if the BIOS does
+ not supply these tables.
+
+ 6th Generation: powernow-k6
+
+ 7th Generation: powernow-k7: Athlon, Duron, Geode.
+
+ 8th Generation: powernow-k8: Athlon, Athlon 64, Opteron, Sempron.
+ Documentation on this functionality in 8th generation processors
+ is available in the "BIOS and Kernel Developer's Guide", publication
+ 26094, in chapter 9, available for download from www.amd.com.
+
+ BIOS supplied data, for powernow-k7 and for powernow-k8, may be
+ from either the PSB table or from ACPI objects. The ACPI support
+ is only available if the kernel config sets CONFIG_ACPI_PROCESSOR.
+ The powernow-k8 driver will attempt to use ACPI if so configured,
+ and fall back to PST if that fails.
+ The powernow-k7 driver will try to use the PSB support first, and
+ fall back to ACPI if the PSB support fails. A module parameter,
+ acpi_force, is provided to force ACPI support to be used instead
+ of PSB support.

+===================
+
+::
+
+ The cpufreq-nforce2 driver changes the FSB on nVidia nForce2 platforms.
+
+ This works better than on other platforms, because the FSB of the CPU
+ can be controlled independently from the PCI/AGP clock.
+
+ The module has two options:
+
+ 	fid: 	 multiplier * 10 (for example 8.5 = 85)
+ 	min_fsb: minimum FSB
+
+ If not set, fid is calculated from the current CPU speed and the FSB.
+ min_fsb defaults to FSB at boot time - 50 MHz.
+
+ IMPORTANT: The available range is limited downwards!
+            Also the minimum available FSB can differ, for systems
+            booting with 200 MHz, 150 should always work.

+
+ 1. Introduction:
+ ----------------
+ Processor Clocking Control (PCC) is an interface between the platform
+ firmware and OSPM. It is a mechanism for coordinating processor
+ performance (ie: frequency) between the platform firmware and the OS.
+
+ The PCC driver (pcc-cpufreq) allows OSPM to take advantage of the PCC
+ interface.
+
+ OS utilizes the PCC interface to inform platform firmware what frequency the
+ OS wants for a logical processor. The platform firmware attempts to achieve
+ the requested frequency. If the request for the target frequency could not be
+ satisfied by platform firmware, then it usually means that power budget
+ conditions are in place, and "power capping" is taking place.
+
+ 1.1 PCC interface:
+ ------------------
+ The complete PCC specification is available here:
+ https://acpica.org/sites/acpica/files/Processor-Clocking-Control-v1p0.pdf
+
+ PCC relies on a shared memory region that provides a channel for communication
+ between the OS and platform firmware. PCC also implements a "doorbell" that
+ is used by the OS to inform the platform firmware that a command has been
+ sent.
+
+ The ACPI PCCH() method is used to discover the location of the PCC shared
+ memory region. The shared memory region header contains the "command" and
+ "status" interface. PCCH() also contains details on how to access the platform
+ doorbell.
+
+ The following commands are supported by the PCC interface:
+ * Get Average Frequency
+ * Set Desired Frequency
+
+ The ACPI PCCP() method is implemented for each logical processor and is
+ used to discover the offsets for the input and output buffers in the shared
+ memory region.
+
+ When PCC mode is enabled, the platform will not expose processor performance
+ or throttle states (_PSS, _TSS and related ACPI objects) to OSPM. Therefore,
+ the native P-state driver (such as acpi-cpufreq for Intel, powernow-k8 for
+ AMD) will not load.
+
+ However, OSPM remains in control of policy. The governor (eg: "ondemand")
+ computes the required performance for each processor based on server workload.
+ The PCC driver fills in the command interface, and the input buffer and
+ communicates the request to the platform firmware. The platform firmware is
+ responsible for delivering the requested performance.
+
+ Each PCC command is "global" in scope and can affect all the logical CPUs in
+ the system. Therefore, PCC is capable of performing "group" updates. With PCC
+ the OS is capable of getting/setting the frequency of all the logical CPUs in
+ the system with a single call to the BIOS.
+
+ 1.1.1 Get Average Frequency:
+ ----------------------------
+ This command is used by the OSPM to query the running frequency of the
+ processor since the last time this command was completed. The output buffer
+ indicates the average unhalted frequency of the logical processor expressed as
+ a percentage of the nominal (ie: maximum) CPU frequency. The output buffer
+ also signifies if the CPU frequency is limited by a power budget condition.
+
+ 1.1.2 Set Desired Frequency:
+ ----------------------------
+ This command is used by the OSPM to communicate to the platform firmware the
+ desired frequency for a logical processor. The output buffer is currently
+ ignored by OSPM. The next invocation of "Get Average Frequency" will inform
+ OSPM if the desired frequency was achieved or not.
+
+ 1.2 Platforms affected:
+ -----------------------
+ The PCC driver will load on any system where the platform firmware:
+ * supports the PCC interface, and the associated PCCH() and PCCP() methods
+ * assumes responsibility for managing the hardware clocking controls in order
+ to deliver the requested processor performance
+
+ Currently, certain HP ProLiant platforms implement the PCC interface. On those
+ platforms PCC is the "default" choice.
+
+ However, it is possible to disable this interface via a BIOS setting. In
+ such an instance, as is also the case on platforms where the PCC interface
+ is not implemented, the PCC driver will fail to load silently.
+
+ 2. Driver and /sys details:
+ ---------------------------
+ When the driver loads, it merely prints the lowest and the highest CPU
+ frequencies supported by the platform firmware.
+
+ The PCC driver loads with a message such as:
+ pcc-cpufreq: (v1.00.00) driver loaded with frequency limits: 1600 MHz, 2933
+ MHz
+
+ This means that the OPSM can request the CPU to run at any frequency in
+ between the limits (1600 MHz, and 2933 MHz) specified in the message.
+
+ Internally, there is no need for the driver to convert the "target" frequency
+ to a corresponding P-state.
+
+ The VERSION number for the driver will be of the format v.xy.ab.
+ eg: 1.00.02
+    ----- --
+     |    |
+     |    -- this will increase with bug fixes/enhancements to the driver
+     |-- this is the version of the PCC specification the driver adheres to
+
+
+ The following is a brief discussion on some of the fields exported via the
+ /sys filesystem and how their values are affected by the PCC driver:
+
+ 2.1 scaling_available_frequencies:
+ ----------------------------------
+ scaling_available_frequencies is not created in /sys. No intermediate
+ frequencies need to be listed because the BIOS will try to achieve any
+ frequency, within limits, requested by the governor. A frequency does not have
+ to be strictly associated with a P-state.
+
+ 2.2 cpuinfo_transition_latency:
+ -------------------------------
+ The cpuinfo_transition_latency field is 0. The PCC specification does
+ not include a field to expose this value currently.
+
+ 2.3 cpuinfo_cur_freq:
+ ---------------------
+ A) Often cpuinfo_cur_freq will show a value different than what is declared
+ in the scaling_available_frequencies or scaling_cur_freq, or scaling_max_freq.
+ This is due to "turbo boost" available on recent Intel processors. If certain
+ conditions are met the BIOS can achieve a slightly higher speed than requested
+ by OSPM. An example:
+
+ scaling_cur_freq	: 2933000
+ cpuinfo_cur_freq	: 3196000
+
+ B) There is a round-off error associated with the cpuinfo_cur_freq value.
+ Since the driver obtains the current frequency as a "percentage" (%) of the
+ nominal frequency from the BIOS, sometimes, the values displayed by
+ scaling_cur_freq and cpuinfo_cur_freq may not match. An example:
+
+ scaling_cur_freq	: 1600000
+ cpuinfo_cur_freq	: 1583000
+
+ In this example, the nominal frequency is 2933 MHz. The driver obtains the
+ current frequency, cpuinfo_cur_freq, as 54% of the nominal frequency:
+
+ 	54% of 2933 MHz = 1583 MHz
+
+ Nominal frequency is the maximum frequency of the processor, and it usually
+ corresponds to the frequency of the P0 P-state.
+
+ 2.4 related_cpus:
+ -----------------
+ The related_cpus field is identical to affected_cpus.
+
+ affected_cpus	: 4
+ related_cpus	: 4
+
+ Currently, the PCC driver does not evaluate _PSD. The platforms that support
+ PCC do not implement SW_ALL. So OSPM doesn't need to perform any coordination
+ to ensure that the same frequency is requested of all dependent CPUs.
+
+ 3. Caveats:
+ -----------
+ The "cpufreq_stats" module in its present form cannot be loaded and
+ expected to work with the PCC driver. Since the "cpufreq_stats" module
+ provides information wrt each P-state, it is not applicable to the PCC driver.

+System Suspend Code Flows
+=========================
+
+:Copyright: |copy| 2020 Intel Corporation
+
+:Author: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
+
+At least one global system-wide transition needs to be carried out for the
+system to get from the working state into one of the supported
+:doc:`sleep states <sleep-states>`.  Hibernation requires more than one
+transition to occur for this purpose, but the other sleep states, commonly
+referred to as *system-wide suspend* (or simply *system suspend*) states, need
+only one.
+
+For those sleep states, the transition from the working state of the system into
+the target sleep state is referred to as *system suspend* too (in the majority
+of cases, whether this means a transition or a sleep state of the system should
+be clear from the context) and the transition back from the sleep state into the
+working state is referred to as *system resume*.
+
+The kernel code flows associated with the suspend and resume transitions for
+different sleep states of the system are quite similar, but there are some
+significant differences between the :ref:`suspend-to-idle <s2idle>` code flows
+and the code flows related to the :ref:`suspend-to-RAM <s2ram>` and
+:ref:`standby <standby>` sleep states.
+
+The :ref:`suspend-to-RAM <s2ram>` and :ref:`standby <standby>` sleep states
+cannot be implemented without platform support and the difference between them
+boils down to the platform-specific actions carried out by the suspend and
+resume hooks that need to be provided by the platform driver to make them
+available.  Apart from that, the suspend and resume code flows for these sleep
+states are mostly identical, so they both together will be referred to as
+*platform-dependent suspend* states in what follows.
+
+
+.. _s2idle_suspend:
+
+Suspend-to-idle Suspend Code Flow
+=================================
+
+The following steps are taken in order to transition the system from the working
+state to the :ref:`suspend-to-idle <s2idle>` sleep state:
+
+ 1. Invoking system-wide suspend notifiers.
+
+    Kernel subsystems can register callbacks to be invoked when the suspend
+    transition is about to occur and when the resume transition has finished.
+
+    That allows them to prepare for the change of the system state and to clean
+    up after getting back to the working state.
+
+ 2. Freezing tasks.
+
+    Tasks are frozen primarily in order to avoid unchecked hardware accesses
+    from user space through MMIO regions or I/O registers exposed directly to
+    it and to prevent user space from entering the kernel while the next step
+    of the transition is in progress (which might have been problematic for
+    various reasons).
+
+    All user space tasks are intercepted as though they were sent a signal and
+    put into uninterruptible sleep until the end of the subsequent system resume
+    transition.
+
+    The kernel threads that choose to be frozen during system suspend for
+    specific reasons are frozen subsequently, but they are not intercepted.
+    Instead, they are expected to periodically check whether or not they need
+    to be frozen and to put themselves into uninterruptible sleep if so.  [Note,
+    however, that kernel threads can use locking and other concurrency controls
+    available in kernel space to synchronize themselves with system suspend and
+    resume, which can be much more precise than the freezing, so the latter is
+    not a recommended option for kernel threads.]
+
+ 3. Suspending devices and reconfiguring IRQs.
+
+    Devices are suspended in four phases called *prepare*, *suspend*,
+    *late suspend* and *noirq suspend* (see :ref:`driverapi_pm_devices` for more
+    information on what exactly happens in each phase).
+
+    Every device is visited in each phase, but typically it is not physically
+    accessed in more than two of them.
+
+    The runtime PM API is disabled for every device during the *late* suspend
+    phase and high-level ("action") interrupt handlers are prevented from being
+    invoked before the *noirq* suspend phase.
+
+    Interrupts are still handled after that, but they are only acknowledged to
+    interrupt controllers without performing any device-specific actions that
+    would be triggered in the working state of the system (those actions are
+    deferred till the subsequent system resume transition as described
+    `below <s2idle_resume_>`_).
+
+    IRQs associated with system wakeup devices are "armed" so that the resume
+    transition of the system is started when one of them signals an event.
+
+ 4. Freezing the scheduler tick and suspending timekeeping.
+
+    When all devices have been suspended, CPUs enter the idle loop and are put
+    into the deepest available idle state.  While doing that, each of them
+    "freezes" its own scheduler tick so that the timer events associated with
+    the tick do not occur until the CPU is woken up by another interrupt source.
+
+    The last CPU to enter the idle state also stops the timekeeping which
+    (among other things) prevents high resolution timers from triggering going
+    forward until the first CPU that is woken up restarts the timekeeping.
+    That allows the CPUs to stay in the deep idle state relatively long in one
+    go.
+
+    From this point on, the CPUs can only be woken up by non-timer hardware
+    interrupts.  If that happens, they go back to the idle state unless the
+    interrupt that woke up one of them comes from an IRQ that has been armed for
+    system wakeup, in which case the system resume transition is started.
+
+
+.. _s2idle_resume:
+
+Suspend-to-idle Resume Code Flow
+================================
+
+The following steps are taken in order to transition the system from the
+:ref:`suspend-to-idle <s2idle>` sleep state into the working state:
+
+ 1. Resuming timekeeping and unfreezing the scheduler tick.
+
+    When one of the CPUs is woken up (by a non-timer hardware interrupt), it
+    leaves the idle state entered in the last step of the preceding suspend
+    transition, restarts the timekeeping (unless it has been restarted already
+    by another CPU that woke up earlier) and the scheduler tick on that CPU is
+    unfrozen.
+
+    If the interrupt that has woken up the CPU was armed for system wakeup,
+    the system resume transition begins.
+
+ 2. Resuming devices and restoring the working-state configuration of IRQs.
+
+    Devices are resumed in four phases called *noirq resume*, *early resume*,
+    *resume* and *complete* (see :ref:`driverapi_pm_devices` for more
+    information on what exactly happens in each phase).
+
+    Every device is visited in each phase, but typically it is not physically
+    accessed in more than two of them.
+
+    The working-state configuration of IRQs is restored after the *noirq* resume
+    phase and the runtime PM API is re-enabled for every device whose driver
+    supports it during the *early* resume phase.
+
+ 3. Thawing tasks.
+
+    Tasks frozen in step 2 of the preceding `suspend <s2idle_suspend_>`_
+    transition are "thawed", which means that they are woken up from the
+    uninterruptible sleep that they went into at that time and user space tasks
+    are allowed to exit the kernel.
+
+ 4. Invoking system-wide resume notifiers.
+
+    This is analogous to step 1 of the `suspend <s2idle_suspend_>`_ transition
+    and the same set of callbacks is invoked at this point, but a different
+    "notification type" parameter value is passed to them.
+
+
+Platform-dependent Suspend Code Flow
+====================================
+
+The following steps are taken in order to transition the system from the working
+state to platform-dependent suspend state:
+
+ 1. Invoking system-wide suspend notifiers.
+
+    This step is the same as step 1 of the suspend-to-idle suspend transition
+    described `above <s2idle_suspend_>`_.
+
+ 2. Freezing tasks.
+
+    This step is the same as step 2 of the suspend-to-idle suspend transition
+    described `above <s2idle_suspend_>`_.
+
+ 3. Suspending devices and reconfiguring IRQs.
+
+    This step is analogous to step 3 of the suspend-to-idle suspend transition
+    described `above <s2idle_suspend_>`_, but the arming of IRQs for system
+    wakeup generally does not have any effect on the platform.
+
+    There are platforms that can go into a very deep low-power state internally
+    when all CPUs in them are in sufficiently deep idle states and all I/O
+    devices have been put into low-power states.  On those platforms,
+    suspend-to-idle can reduce system power very effectively.
+
+    On the other platforms, however, low-level components (like interrupt
+    controllers) need to be turned off in a platform-specific way (implemented
+    in the hooks provided by the platform driver) to achieve comparable power
+    reduction.
+
+    That usually prevents in-band hardware interrupts from waking up the system,
+    which must be done in a special platform-dependent way.  Then, the
+    configuration of system wakeup sources usually starts when system wakeup
+    devices are suspended and is finalized by the platform suspend hooks later
+    on.
+
+ 4. Disabling non-boot CPUs.
+
+    On some platforms the suspend hooks mentioned above must run in a one-CPU
+    configuration of the system (in particular, the hardware cannot be accessed
+    by any code running in parallel with the platform suspend hooks that may,
+    and often do, trap into the platform firmware in order to finalize the
+    suspend transition).
+
+    For this reason, the CPU offline/online (CPU hotplug) framework is used
+    to take all of the CPUs in the system, except for one (the boot CPU),
+    offline (typically, the CPUs that have been taken offline go into deep idle
+    states).
+
+    This means that all tasks are migrated away from those CPUs and all IRQs are
+    rerouted to the only CPU that remains online.
+
+ 5. Suspending core system components.
+
+    This prepares the core system components for (possibly) losing power going
+    forward and suspends the timekeeping.
+
+ 6. Platform-specific power removal.
+
+    This is expected to remove power from all of the system components except
+    for the memory controller and RAM (in order to preserve the contents of the
+    latter) and some devices designated for system wakeup.
+
+    In many cases control is passed to the platform firmware which is expected
+    to finalize the suspend transition as needed.
+
+
+Platform-dependent Resume Code Flow
+===================================
+
+The following steps are taken in order to transition the system from a
+platform-dependent suspend state into the working state:
+
+ 1. Platform-specific system wakeup.
+
+    The platform is woken up by a signal from one of the designated system
+    wakeup devices (which need not be an in-band hardware interrupt)  and
+    control is passed back to the kernel (the working configuration of the
+    platform may need to be restored by the platform firmware before the
+    kernel gets control again).
+
+ 2. Resuming core system components.
+
+    The suspend-time configuration of the core system components is restored and
+    the timekeeping is resumed.
+
+ 3. Re-enabling non-boot CPUs.
+
+    The CPUs disabled in step 4 of the preceding suspend transition are taken
+    back online and their suspend-time configuration is restored.
+
+ 4. Resuming devices and restoring the working-state configuration of IRQs.
+
+    This step is the same as step 2 of the suspend-to-idle suspend transition
+    described `above <s2idle_resume_>`_.
+
+ 5. Thawing tasks.
+
+    This step is the same as step 3 of the suspend-to-idle suspend transition
+    described `above <s2idle_resume_>`_.
+
+ 6. Invoking system-wide resume notifiers.
+
+    This step is the same as step 4 of the suspend-to-idle suspend transition
+    described `above <s2idle_resume_>`_.

+=======================================================
+Activity Monitors Unit (AMU) extension in AArch64 Linux
+=======================================================
+
+Author: Ionela Voinescu <ionela.voinescu@arm.com>
+
+Date: 2019-09-10
+
+This document briefly describes the provision of Activity Monitors Unit
+support in AArch64 Linux.
+
+
+Architecture overview
+---------------------
+
+The activity monitors extension is an optional extension introduced by the
+ARMv8.4 CPU architecture.
+
+The activity monitors unit, implemented in each CPU, provides performance
+counters intended for system management use. The AMU extension provides a
+system register interface to the counter registers and also supports an
+optional external memory-mapped interface.
+
+Version 1 of the Activity Monitors architecture implements a counter group
+of four fixed and architecturally defined 64-bit event counters.
+
+- CPU cycle counter: increments at the frequency of the CPU.
+- Constant counter: increments at the fixed frequency of the system
+  clock.
+- Instructions retired: increments with every architecturally executed
+  instruction.
+- Memory stall cycles: counts instruction dispatch stall cycles caused by
+  misses in the last level cache within the clock domain.
+
+When in WFI or WFE these counters do not increment.
+
+The Activity Monitors architecture provides space for up to 16 architected
+event counters. Future versions of the architecture may use this space to
+implement additional architected event counters.
+
+Additionally, version 1 implements a counter group of up to 16 auxiliary
+64-bit event counters.
+
+On cold reset all counters reset to 0.
+
+
+Basic support
+-------------
+
+The kernel can safely run a mix of CPUs with and without support for the
+activity monitors extension. Therefore, when CONFIG_ARM64_AMU_EXTN is
+selected we unconditionally enable the capability to allow any late CPU
+(secondary or hotplugged) to detect and use the feature.
+
+When the feature is detected on a CPU, we flag the availability of the
+feature but this does not guarantee the correct functionality of the
+counters, only the presence of the extension.
+
+Firmware (code running at higher exception levels, e.g. arm-tf) support is
+needed to:
+
+- Enable access for lower exception levels (EL2 and EL1) to the AMU
+  registers.
+- Enable the counters. If not enabled these will read as 0.
+- Save/restore the counters before/after the CPU is being put/brought up
+  from the 'off' power state.
+
+When using kernels that have this feature enabled but boot with broken
+firmware the user may experience panics or lockups when accessing the
+counter registers. Even if these symptoms are not observed, the values
+returned by the register reads might not correctly reflect reality. Most
+commonly, the counters will read as 0, indicating that they are not
+enabled.
+
+If proper support is not provided in firmware it's best to disable
+CONFIG_ARM64_AMU_EXTN. To be noted that for security reasons, this does not
+bypass the setting of AMUSERENR_EL0 to trap accesses from EL0 (userspace) to
+EL1 (kernel). Therefore, firmware should still ensure accesses to AMU registers
+are not trapped in EL2/EL3.
+
+The fixed counters of AMUv1 are accessible though the following system
+register definitions:
+
+- SYS_AMEVCNTR0_CORE_EL0
+- SYS_AMEVCNTR0_CONST_EL0
+- SYS_AMEVCNTR0_INST_RET_EL0
+- SYS_AMEVCNTR0_MEM_STALL_EL0
+
+Auxiliary platform specific counters can be accessed using
+SYS_AMEVCNTR1_EL0(n), where n is a value between 0 and 15.
+
+Details can be found in: arch/arm64/include/asm/sysreg.h.
+
+
+Userspace access
+----------------
+
+Currently, access from userspace to the AMU registers is disabled due to:
+
+- Security reasons: they might expose information about code executed in
+  secure mode.
+- Purpose: AMU counters are intended for system management use.
+
+Also, the presence of the feature is not visible to userspace.
+
+
+Virtualization
+--------------
+
+Currently, access from userspace (EL0) and kernelspace (EL1) on the KVM
+guest side is disabled due to:
+
+- Security reasons: they might expose information about code executed
+  by other guests or the host.
+
+Any attempt to access the AMU registers will result in an UNDEFINED
+exception being injected into the guest.

+================
+LSM BPF Programs
+================
+
+These BPF programs allow runtime instrumentation of the LSM hooks by privileged
+users to implement system-wide MAC (Mandatory Access Control) and Audit
+policies using eBPF.
+
+Structure
+---------
+
+The example shows an eBPF program that can be attached to the ``file_mprotect``
+LSM hook:
+
+.. c:function:: int file_mprotect(struct vm_area_struct *vma, unsigned long reqprot, unsigned long prot);
+
+Other LSM hooks which can be instrumented can be found in
+``include/linux/lsm_hooks.h``.
+
+eBPF programs that use :doc:`/bpf/btf` do not need to include kernel headers
+for accessing information from the attached eBPF program's context. They can
+simply declare the structures in the eBPF program and only specify the fields
+that need to be accessed.
+
+.. code-block:: c
+
+	struct mm_struct {
+		unsigned long start_brk, brk, start_stack;
+	} __attribute__((preserve_access_index));
+
+	struct vm_area_struct {
+		unsigned long start_brk, brk, start_stack;
+		unsigned long vm_start, vm_end;
+		struct mm_struct *vm_mm;
+	} __attribute__((preserve_access_index));
+
+
+.. note:: The order of the fields is irrelevant.
+
+This can be further simplified (if one has access to the BTF information at
+build time) by generating the ``vmlinux.h`` with:
+
+.. code-block:: console
+
+	# bpftool btf dump file <path-to-btf-vmlinux> format c > vmlinux.h
+
+.. note:: ``path-to-btf-vmlinux`` can be ``/sys/kernel/btf/vmlinux`` if the
+	  build environment matches the environment the BPF programs are
+	  deployed in.
+
+The ``vmlinux.h`` can then simply be included in the BPF programs without
+requiring the definition of the types.
+
+The eBPF programs can be declared using the``BPF_PROG``
+macros defined in `tools/lib/bpf/bpf_tracing.h`_. In this
+example:
+
+	* ``"lsm/file_mprotect"`` indicates the LSM hook that the program must
+	  be attached to
+	* ``mprotect_audit`` is the name of the eBPF program
+
+.. code-block:: c
+
+	SEC("lsm/file_mprotect")
+	int BPF_PROG(mprotect_audit, struct vm_area_struct *vma,
+		     unsigned long reqprot, unsigned long prot, int ret)
+	{
+		/* ret is the return value from the previous BPF program
+		 * or 0 if it's the first hook.
+		 */
+		if (ret != 0)
+			return ret;
+
+		int is_heap;
+
+		is_heap = (vma->vm_start >= vma->vm_mm->start_brk &&
+			   vma->vm_end <= vma->vm_mm->brk);
+
+		/* Return an -EPERM or write information to the perf events buffer
+		 * for auditing
+		 */
+		if (is_heap)
+			return -EPERM;
+	}
+
+The ``__attribute__((preserve_access_index))`` is a clang feature that allows
+the BPF verifier to update the offsets for the access at runtime using the
+:doc:`/bpf/btf` information. Since the BPF verifier is aware of the types, it
+also validates all the accesses made to the various types in the eBPF program.
+
+Loading
+-------
+
+eBPF programs can be loaded with the :manpage:`bpf(2)` syscall's
+``BPF_PROG_LOAD`` operation:
+
+.. code-block:: c
+
+	struct bpf_object *obj;
+
+	obj = bpf_object__open("./my_prog.o");
+	bpf_object__load(obj);
+
+This can be simplified by using a skeleton header generated by ``bpftool``:
+
+.. code-block:: console
+
+	# bpftool gen skeleton my_prog.o > my_prog.skel.h
+
+and the program can be loaded by including ``my_prog.skel.h`` and using
+the generated helper, ``my_prog__open_and_load``.
+
+Attachment to LSM Hooks
+-----------------------
+
+The LSM allows attachment of eBPF programs as LSM hooks using :manpage:`bpf(2)`
+syscall's ``BPF_RAW_TRACEPOINT_OPEN`` operation or more simply by
+using the libbpf helper ``bpf_program__attach_lsm``.
+
+The program can be detached from the LSM hook by *destroying* the ``link``
+link returned by ``bpf_program__attach_lsm`` using ``bpf_link__destroy``.
+
+One can also use the helpers generated in ``my_prog.skel.h`` i.e.
+``my_prog__attach`` for attachment and ``my_prog__destroy`` for cleaning up.
+
+Examples
+--------
+
+An example eBPF program can be found in
+`tools/testing/selftests/bpf/progs/lsm.c`_ and the corresponding
+userspace code in `tools/testing/selftests/bpf/prog_tests/test_lsm.c`_

+--------------
+
+Description
+===========
+
+`bpf_inspect.py`_ is a tool intended to inspect BPF programs and maps. It can
+iterate over all programs and maps in the system and print basic information
+about these objects, including id, type and name.
+
+The main use-case `bpf_inspect.py`_ covers is to show BPF programs of types
+``BPF_PROG_TYPE_EXT`` and ``BPF_PROG_TYPE_TRACING`` attached to other BPF
+programs via ``freplace``/``fentry``/``fexit`` mechanisms, since there is no
+user-space API to get this information.
+

+
+It can be seen that there is a program ``test_pkt_access``, id 650 and there
+are multiple other tracing and ext programs attached to functions in
+``test_pkt_access``.
+
+For example the line::
+
+         658: BPF_PROG_TYPE_EXT                new_get_skb_len                  linked:[650->16: BPF_TRAMP_REPLACE test_pkt_access->get_skb_len()]
+
+, means that BPF program id 658, type ``BPF_PROG_TYPE_EXT``, name
+``new_get_skb_len`` replaces (``BPF_TRAMP_REPLACE``) function ``get_skb_len()``
+that has BTF id 16 in BPF program id 650, name ``test_pkt_access``.

-
-1. Introduction:
-----------------
-Processor Clocking Control (PCC) is an interface between the platform
-firmware and OSPM. It is a mechanism for coordinating processor
-performance (ie: frequency) between the platform firmware and the OS.
-
-The PCC driver (pcc-cpufreq) allows OSPM to take advantage of the PCC
-interface.
-
-OS utilizes the PCC interface to inform platform firmware what frequency the
-OS wants for a logical processor. The platform firmware attempts to achieve
-the requested frequency. If the request for the target frequency could not be
-satisfied by platform firmware, then it usually means that power budget
-conditions are in place, and "power capping" is taking place.
-
-1.1 PCC interface:
-------------------
-The complete PCC specification is available here:
-http://www.acpica.org/download/Processor-Clocking-Control-v1p0.pdf
-
-PCC relies on a shared memory region that provides a channel for communication
-between the OS and platform firmware. PCC also implements a "doorbell" that
-is used by the OS to inform the platform firmware that a command has been
-sent.
-
-The ACPI PCCH() method is used to discover the location of the PCC shared
-memory region. The shared memory region header contains the "command" and
-"status" interface. PCCH() also contains details on how to access the platform
-doorbell.
-
-The following commands are supported by the PCC interface:
-* Get Average Frequency
-* Set Desired Frequency
-
-The ACPI PCCP() method is implemented for each logical processor and is
-used to discover the offsets for the input and output buffers in the shared
-memory region.
-
-When PCC mode is enabled, the platform will not expose processor performance
-or throttle states (_PSS, _TSS and related ACPI objects) to OSPM. Therefore,
-the native P-state driver (such as acpi-cpufreq for Intel, powernow-k8 for
-AMD) will not load.
-
-However, OSPM remains in control of policy. The governor (eg: "ondemand")
-computes the required performance for each processor based on server workload.
-The PCC driver fills in the command interface, and the input buffer and
-communicates the request to the platform firmware. The platform firmware is
-responsible for delivering the requested performance.
-
-Each PCC command is "global" in scope and can affect all the logical CPUs in
-the system. Therefore, PCC is capable of performing "group" updates. With PCC
-the OS is capable of getting/setting the frequency of all the logical CPUs in
-the system with a single call to the BIOS.
-
-1.1.1 Get Average Frequency:
-----------------------------
-This command is used by the OSPM to query the running frequency of the
-processor since the last time this command was completed. The output buffer
-indicates the average unhalted frequency of the logical processor expressed as
-a percentage of the nominal (ie: maximum) CPU frequency. The output buffer
-also signifies if the CPU frequency is limited by a power budget condition.
-
-1.1.2 Set Desired Frequency:
-----------------------------
-This command is used by the OSPM to communicate to the platform firmware the
-desired frequency for a logical processor. The output buffer is currently
-ignored by OSPM. The next invocation of "Get Average Frequency" will inform
-OSPM if the desired frequency was achieved or not.
-
-1.2 Platforms affected:
------------------------
-The PCC driver will load on any system where the platform firmware:
-* supports the PCC interface, and the associated PCCH() and PCCP() methods
-* assumes responsibility for managing the hardware clocking controls in order
-to deliver the requested processor performance
-
-Currently, certain HP ProLiant platforms implement the PCC interface. On those
-platforms PCC is the "default" choice.
-
-However, it is possible to disable this interface via a BIOS setting. In
-such an instance, as is also the case on platforms where the PCC interface
-is not implemented, the PCC driver will fail to load silently.
-
-2. Driver and /sys details:
----------------------------
-When the driver loads, it merely prints the lowest and the highest CPU
-frequencies supported by the platform firmware.
-
-The PCC driver loads with a message such as:
-pcc-cpufreq: (v1.00.00) driver loaded with frequency limits: 1600 MHz, 2933
-MHz
-
-This means that the OPSM can request the CPU to run at any frequency in
-between the limits (1600 MHz, and 2933 MHz) specified in the message.
-
-Internally, there is no need for the driver to convert the "target" frequency
-to a corresponding P-state.
-
-The VERSION number for the driver will be of the format v.xy.ab.
-eg: 1.00.02
-   ----- --
-    |    |
-    |    -- this will increase with bug fixes/enhancements to the driver
-    |-- this is the version of the PCC specification the driver adheres to
-
-
-The following is a brief discussion on some of the fields exported via the
-/sys filesystem and how their values are affected by the PCC driver:
-
-2.1 scaling_available_frequencies:
-----------------------------------
-scaling_available_frequencies is not created in /sys. No intermediate
-frequencies need to be listed because the BIOS will try to achieve any
-frequency, within limits, requested by the governor. A frequency does not have
-to be strictly associated with a P-state.
-
-2.2 cpuinfo_transition_latency:
--------------------------------
-The cpuinfo_transition_latency field is 0. The PCC specification does
-not include a field to expose this value currently.
-
-2.3 cpuinfo_cur_freq:
----------------------
-A) Often cpuinfo_cur_freq will show a value different than what is declared
-in the scaling_available_frequencies or scaling_cur_freq, or scaling_max_freq.
-This is due to "turbo boost" available on recent Intel processors. If certain
-conditions are met the BIOS can achieve a slightly higher speed than requested
-by OSPM. An example:
-
-scaling_cur_freq	: 2933000
-cpuinfo_cur_freq	: 3196000
-
-B) There is a round-off error associated with the cpuinfo_cur_freq value.
-Since the driver obtains the current frequency as a "percentage" (%) of the
-nominal frequency from the BIOS, sometimes, the values displayed by
-scaling_cur_freq and cpuinfo_cur_freq may not match. An example:
-
-scaling_cur_freq	: 1600000
-cpuinfo_cur_freq	: 1583000
-
-In this example, the nominal frequency is 2933 MHz. The driver obtains the
-current frequency, cpuinfo_cur_freq, as 54% of the nominal frequency:
-
-	54% of 2933 MHz = 1583 MHz
-
-Nominal frequency is the maximum frequency of the processor, and it usually
-corresponds to the frequency of the P0 P-state.
-
-2.4 related_cpus:
------------------
-The related_cpus field is identical to affected_cpus.
-
-affected_cpus	: 4
-related_cpus	: 4
-
-Currently, the PCC driver does not evaluate _PSD. The platforms that support
-PCC do not implement SW_ALL. So OSPM doesn't need to perform any coordination
-to ensure that the same frequency is requested of all dependent CPUs.
-
-3. Caveats:
------------
-The "cpufreq_stats" module in its present form cannot be loaded and
-expected to work with the PCC driver. Since the "cpufreq_stats" module
-provides information wrt each P-state, it is not applicable to the PCC driver.

-Debugging Modules after 2.6.3
------------------------------
-
-In almost all distributions, the kernel asks for modules which don't
-exist, such as "net-pf-10" or whatever.  Changing "modprobe -q" to
-"succeed" in this case is hacky and breaks some setups, and also we
-want to know if it failed for the fallback code for old aliases in
-fs/char_dev.c, for example.
-
-In the past a debugging message which would fill people's logs was
-emitted.  This debugging message has been removed.  The correct way
-of debugging module problems is something like this:
-
-echo '#! /bin/sh' > /tmp/modprobe
-echo 'echo "$@" >> /tmp/modprobe.log' >> /tmp/modprobe
-echo 'exec /sbin/modprobe "$@"' >> /tmp/modprobe
-chmod a+x /tmp/modprobe
-echo /tmp/modprobe > /proc/sys/kernel/modprobe
-
-Note that the above applies only when the *kernel* is requesting
-that the module be loaded -- it won't have any effect if that module
-is being loaded explicitly using "modprobe" from userspace.

 ==============
 
 KUnit is a lightweight unit testing and mocking framework for the Linux kernel.
-These tests are able to be run locally on a developer's workstation without a VM
-or special hardware.
 
 KUnit is heavily inspired by JUnit, Python's unittest.mock, and
 Googletest/Googlemock for C++. KUnit provides facilities for defining unit test
 cases, grouping related test cases into test suites, providing common
 infrastructure for running tests, and much more.
 
+KUnit consists of a kernel component, which provides a set of macros for easily
+writing unit tests. Tests written against KUnit will run on kernel boot if
+built-in, or when loaded if built as a module. These tests write out results to
+the kernel log in `TAP <https://testanything.org/>`_ format.
+
+To make running these tests (and reading the results) easier, KUnit offers
+:doc:`kunit_tool <kunit-tool>`, which builds a `User Mode Linux
+<http://user-mode-linux.sourceforge.net>`_ kernel, runs it, and parses the test
+results. This provides a quick way of running KUnit tests during development,
+without requiring a virtual machine or separate hardware.

+-----------------------
+If you want to run a specific set of tests (rather than those listed in the
+KUnit defconfig), you can provide Kconfig options in the ``.kunitconfig`` file.
+This file essentially contains the regular Kernel config, with the specific
+test targets as well. The ``.kunitconfig`` should also contain any other config
+options required by the tests.
+
+A good starting point for a ``.kunitconfig`` is the KUnit defconfig:

 	cd $PATH_TO_LINUX_REPO
 	cp arch/um/configs/kunit_defconfig .kunitconfig
 
-Verifying KUnit Works

+.. code-block:: none

+        CONFIG_LIST_KUNIT_TEST=y

+
+Configuring the kernel
+----------------------
+
+In order to enable KUnit itself, you simply need to enable the ``CONFIG_KUNIT``

+description: |+
+  ARM's Versatile Express platform were built as reference designs for exploring
+  multicore Cortex-A class systems. The Versatile Express family contains both
+  32 bit (Aarch32) and 64 bit (Aarch64) systems.
+
+  The board consist of a motherboard and one or more daughterboards (tiles). The
+  motherboard provides a set of peripherals. Processor and RAM "live" on the
+  tiles.
+
+  The motherboard and each core tile should be described by a separate Device
+  Tree source file, with the tile's description including the motherboard file
+  using an include directive. As the motherboard can be initialized in one of
+  two different configurations ("memory maps"), care must be taken to include
+  the correct one.
+
+  When a new generation of boards were introduced under the name "Juno", these
+  shared to many common characteristics with the Versatile Express that the
+  "arm,vexpress" compatible was retained in the root node, and these are
+  included in this binding schema as well.
+
+  The root node indicates the CPU SoC on the core tile, and this
+  is a daughterboard to the main motherboard. The name used in the compatible
+  string shall match the name given in the core tile's technical reference
+  manual, followed by "arm,vexpress" as an additional compatible value. If
+  further subvariants are released of the core tile, even more fine-granular
+  compatible strings with up to three compatible strings are used.

-ARM Versatile Express Boards
------------------------------
-For details on the device tree bindings for ARM Versatile Express boards
-please consult the vexpress.txt file in the same directory as this file.
-
-ARM Juno Boards
-----------------
-The Juno boards are targeting development for AArch64 systems. The first
-iteration, Juno r0, is a vehicle for evaluating big.LITTLE on AArch64,
-with the second iteration, Juno r1, mainly aimed at development of PCIe
-based systems. Juno r1 also has support for AXI masters placed on the TLX
-connectors to join the coherency domain.
-
-Juno boards are described in a similar way to ARM Versatile Express boards,
-with the motherboard part of the hardware being described in a separate file
-to highlight the fact that is part of the support infrastructure for the SoC.
-Juno device tree bindings also share the Versatile Express bindings as
-described under the RS1 memory mapping.
-
-Required properties (in root node):
-	compatible = "arm,juno";	/* For Juno r0 board */
-	compatible = "arm,juno-r1";	/* For Juno r1 board */
-	compatible = "arm,juno-r2";	/* For Juno r2 board */
-
-Required nodes:
-The description for the board must include:
-   - a "psci" node describing the boot method used for the secondary CPUs.
-     A detailed description of the bindings used for "psci" nodes is present
-     in the psci.yaml file.
-   - a "cpus" node describing the available cores and their associated
-     "enable-method"s. For more details see cpus.yaml file.
-
-Example:
-
-/dts-v1/;
-/ {
-	model = "ARM Juno development board (r0)";
-	compatible = "arm,juno", "arm,vexpress";
-	interrupt-parent = <&gic>;
-	#address-cells = <2>;
-	#size-cells = <2>;
-
-	cpus {
-		#address-cells = <2>;
-		#size-cells = <0>;
-
-		A57_0: cpu@0 {
-			compatible = "arm,cortex-a57";
-			reg = <0x0 0x0>;
-			device_type = "cpu";
-			enable-method = "psci";
-		};
-
-		.....
-
-		A53_0: cpu@100 {
-			compatible = "arm,cortex-a53";
-			reg = <0x0 0x100>;
-			device_type = "cpu";
-			enable-method = "psci";
-		};
-

-CPUs in the following Broadcom SoCs:
-  BCM11130, BCM11140, BCM11351, BCM28145, BCM28155, BCM21664
-
-The enable method is specified by defining the following required
-properties in the "cpu" device tree node:

-code release a secondary CPU.  The value written to the register is
-formed by encoding the target CPU id into the low bits of the
-physical start address it should jump to.
-

-Broadcom Northstar Plus SoC CPU Enable Method
----------------------------------------------
-This binding defines the enable method used for starting secondary
-CPU in the following Broadcom SoCs:
-  BCM58522, BCM58525, BCM58535, BCM58622, BCM58623, BCM58625, BCM88312
-
-The enable method is specified by defining the following required
-properties in the corresponding secondary "cpu" device tree node:
-  - enable-method = "brcm,bcm-nsp-smp";
-  - secondary-boot-reg = <...>;
-
-The secondary-boot-reg property is a u32 value that specifies the
-physical address of the register which should hold the common
-entry point for a secondary CPU. This entry is cpu node specific
-and should be added per cpu. E.g., in case of NSP (BCM58625) which
-is a dual core CPU SoC, this entry should be added to cpu1 node.
-
-
-Example:
-	cpus {
-		#address-cells = <1>;
-		#size-cells = <0>;
-
-		cpu0: cpu@0 {
-			device_type = "cpu";
-			compatible = "arm,cortex-a9";
-			next-level-cache = <&L2>;
-			reg = <0>;
-		};
-
-		cpu1: cpu@1 {
-			device_type = "cpu";

+title: ARM Coresight Cross Trigger Interface (CTI) device.
+
+description: |
+  The CoreSight Embedded Cross Trigger (ECT) consists of CTI devices connected
+  to one or more CoreSight components and/or a CPU, with CTIs interconnected in
+  a star topology via the Cross Trigger Matrix (CTM), which is not programmable.
+  The ECT components are not part of the trace generation data path and are thus
+  not part of the CoreSight graph described in the general CoreSight bindings
+  file coresight.txt.
+
+  The CTI component properties define the connections between the individual
+  CTI and the components it is directly connected to, consisting of input and
+  output hardware trigger signals. CTIs can have a maximum number of input and
+  output hardware trigger signals (8 each for v1 CTI, 32 each for v2 CTI). The
+  number is defined at design time, the maximum of each defined in the DEVID
+  register.
+
+  CTIs are interconnected in a star topology via the CTM, using a number of
+  programmable channels, usually 4, but again implementation defined and
+  described in the DEVID register. The star topology is not required to be
+  described in the bindings as the actual connections are software
+  programmable.
+
+  In general the connections between CTI and components via the trigger signals
+  are implementation defined, except when the CTI is connected to an ARM v8
+  architecture core and optional ETM.
+
+  In this case the ARM v8 architecture defines the required signal connections
+  between CTI and the CPU core and ETM if present. In the case of a v8
+  architecturally connected CTI an additional compatible string is used to
+  indicate this feature (arm,coresight-cti-v8-arch).
+
+  When CTI trigger connection information is unavailable then a minimal driver
+  binding can be declared with no explicit trigger signals. This will result
+  the driver detecting the maximum available triggers and channels from the
+  DEVID register and make them all available for use as a single default
+  connection. Any user / client application will require additional information
+  on the connections between the CTI and other components for correct operation.
+  This information might be found by enabling the Integration Test registers in
+  the driver (set CONFIG_CORESIGHT_CTI_INTEGRATION_TEST in Kernel
+  configuration). These registers may be used to explore the trigger connections
+  between CTI and other CoreSight components.
+
+  Certain triggers between CoreSight devices and the CTI have specific types
+  and usages. These can be defined along with the signal indexes with the
+  constants defined in <dt-bindings/arm/coresight-cti-dt.h>
+
+  For example a CTI connected to a core will usually have a DBGREQ signal. This
+  is defined in the binding as type PE_EDBGREQ. These types will appear in an
+  optional array alongside the signal indexes. Omitting types will default all
+  signals to GEN_IO.
+
+  Note that some hardware trigger signals can be connected to non-CoreSight
+  components (e.g. UART etc) depending on hardware implementation.

-UniPhier outer cache controller
-
-UniPhier SoCs are integrated with a full-custom outer cache controller system.
-All of them have a level 2 cache controller, and some have a level 3 cache
-controller as well.
-
-Required properties:
-- compatible: should be "socionext,uniphier-system-cache"
-- reg: offsets and lengths of the register sets for the device.  It should
-  contain 3 regions: control register, revision register, operation register,
-  in this order.
-- cache-unified: specifies the cache is a unified cache.
-- cache-size: specifies the size in bytes of the cache
-- cache-sets: specifies the number of associativity sets of the cache
-- cache-line-size: specifies the line size in bytes
-- cache-level: specifies the level in the cache hierarchy.  The value should
-  be 2 for L2 cache, 3 for L3 cache, etc.
-
-Optional properties:
-- next-level-cache: phandle to the next level cache if present.  The next level
-  cache should be also compatible with "socionext,uniphier-system-cache".
-
-The L2 cache must exist to use the L3 cache; the cache hierarchy must be
-indicated correctly with "next-level-cache" properties.
-
-Example 1 (system with L2):
-	l2: l2-cache@500c0000 {
-		compatible = "socionext,uniphier-system-cache";
-		reg = <0x500c0000 0x2000>, <0x503c0100 0x4>,

-		cache-unified;
-		cache-size = <0x80000>;
-		cache-sets = <256>;
-		cache-line-size = <128>;
-		cache-level = <2>;
-	};

-NVIDIA Tegra Power Management Controller (PMC)
-
-== Power Management Controller Node ==
-
-The PMC block interacts with an external Power Management Unit. The PMC
-mostly controls the entry and exit of the system from different sleep
-modes. It provides power-gating controllers for SoC and CPU power-islands.
-
-Required properties:
-- name : Should be pmc
-- compatible : Should contain one of the following:
-	For Tegra20 must contain "nvidia,tegra20-pmc".
-	For Tegra30 must contain "nvidia,tegra30-pmc".
-	For Tegra114 must contain "nvidia,tegra114-pmc"
-	For Tegra124 must contain "nvidia,tegra124-pmc"
-	For Tegra132 must contain "nvidia,tegra124-pmc"
-	For Tegra210 must contain "nvidia,tegra210-pmc"
-- reg : Offset and length of the register set for the device
-- clocks : Must contain an entry for each entry in clock-names.
-  See ../clocks/clock-bindings.txt for details.
-- clock-names : Must include the following entries:
-  "pclk" (The Tegra clock of that name),
-  "clk32k_in" (The 32KHz clock input to Tegra).
-
-Optional properties:
-- nvidia,invert-interrupt : If present, inverts the PMU interrupt signal.
-  The PMU is an external Power Management Unit, whose interrupt output
-  signal is fed into the PMC. This signal is optionally inverted, and then
-  fed into the ARM GIC. The PMC is not involved in the detection or
-  handling of this interrupt signal, merely its inversion.
-- nvidia,suspend-mode : The suspend mode that the platform should use.
-  Valid values are 0, 1 and 2:
-  0 (LP0): CPU + Core voltage off and DRAM in self-refresh
-  1 (LP1): CPU voltage off and DRAM in self-refresh
-  2 (LP2): CPU voltage off
-- nvidia,core-power-req-active-high : Boolean, core power request active-high
-- nvidia,sys-clock-req-active-high : Boolean, system clock request active-high
-- nvidia,combined-power-req : Boolean, combined power request for CPU & Core
-- nvidia,cpu-pwr-good-en : Boolean, CPU power good signal (from PMIC to PMC)
-			   is enabled.
-
-Required properties when nvidia,suspend-mode is specified:
-- nvidia,cpu-pwr-good-time : CPU power good time in uS.
-- nvidia,cpu-pwr-off-time : CPU power off time in uS.
-- nvidia,core-pwr-good-time : <Oscillator-stable-time Power-stable-time>
-			      Core power good time in uS.
-- nvidia,core-pwr-off-time : Core power off time in uS.
-
-Required properties when nvidia,suspend-mode=<0>:
-- nvidia,lp0-vec : <start length> Starting address and length of LP0 vector
-  The LP0 vector contains the warm boot code that is executed by AVP when
-  resuming from the LP0 state. The AVP (Audio-Video Processor) is an ARM7
-  processor and always being the first boot processor when chip is power on
-  or resume from deep sleep mode. When the system is resumed from the deep
-  sleep mode, the warm boot code will restore some PLLs, clocks and then
-  bring up CPU0 for resuming the system.
-
-Hardware-triggered thermal reset:
-On Tegra30, Tegra114 and Tegra124, if the 'i2c-thermtrip' subnode exists,
-hardware-triggered thermal reset will be enabled.
-
-Required properties for hardware-triggered thermal reset (inside 'i2c-thermtrip'):
-- nvidia,i2c-controller-id : ID of I2C controller to send poweroff command to. Valid values are
-                             described in section 9.2.148 "APBDEV_PMC_SCRATCH53_0" of the
-                             Tegra K1 Technical Reference Manual.
-- nvidia,bus-addr : Bus address of the PMU on the I2C bus
-- nvidia,reg-addr : I2C register address to write poweroff command to
-- nvidia,reg-data : Poweroff command to write to PMU
-
-Optional properties for hardware-triggered thermal reset (inside 'i2c-thermtrip'):
-- nvidia,pinmux-id : Pinmux used by the hardware when issuing poweroff command.
-                     Defaults to 0. Valid values are described in section 12.5.2
-                     "Pinmux Support" of the Tegra4 Technical Reference Manual.
-
-Optional nodes:
-- powergates : This node contains a hierarchy of power domain nodes, which
-	       should match the powergates on the Tegra SoC. See "Powergate
-	       Nodes" below.

-Required properties:
-  - clocks: Must contain an entry for each clock required by the PMC for
-    controlling a power-gate. See ../clocks/clock-bindings.txt for details.
-  - resets: Must contain an entry for each reset required by the PMC for
-    controlling a power-gate. See ../reset/reset.txt for details.
-  - #power-domain-cells: Must be 0.
-
-Example:
-
-	pmc: pmc@7000e400 {
-		compatible = "nvidia,tegra210-pmc";
-		reg = <0x0 0x7000e400 0x0 0x400>;

-				resets = <&tegra_car 198>;
-				#power-domain-cells = <0>;
-			};
-		};
-	};
-
-
-== Powergate Clients ==
-
-Hardware blocks belonging to a power domain should contain a "power-domains"
-property that is a phandle pointing to the corresponding powergate node.
-
-Example:
-
-	adma: adma@702e2000 {
-		...
-		power-domains = <&pd_audio>;
-		...
-	};
-
-== Pad Control ==
-
-On Tegra SoCs a pad is a set of pins which are configured as a group.
-The pin grouping is a fixed attribute of the hardware. The PMC can be
-used to set pad power state and signaling voltage. A pad can be either
-in active or power down mode. The support for power state and signaling
-voltage configuration varies depending on the pad in question. 3.3 V and
-1.8 V signaling voltages are supported on pins where software
-controllable signaling voltage switching is available.
-
-The pad configuration state nodes are placed under the pmc node and they
-are referred to by the pinctrl client properties. For more information
-see Documentation/devicetree/bindings/pinctrl/pinctrl-bindings.txt.
-The pad name should be used as the value of the pins property in pin
-configuration nodes.
-
-The following pads are present on Tegra124 and Tegra132:
-audio		bb		cam		comp
-csia		csb		cse		dsi
-dsib		dsic		dsid		hdmi
-hsic		hv		lvds		mipi-bias
-nand		pex-bias	pex-clk1	pex-clk2
-pex-cntrl	sdmmc1		sdmmc3		sdmmc4
-sys_ddc		uart		usb0		usb1
-usb2		usb_bias
-
-The following pads are present on Tegra210:
-audio		audio-hv	cam		csia
-csib		csic		csid		csie
-csif		dbg		debug-nonao	dmic
-dp		dsi		dsib		dsic
-dsid		emmc		emmc2		gpio
-hdmi		hsic		lvds		mipi-bias
-pex-bias	pex-clk1	pex-clk2	pex-cntrl
-sdmmc1		sdmmc3		spi		spi-hv
-uart		usb0		usb1		usb2
-usb3		usb-bias
-
-Required pin configuration properties:
-  - pins: Must contain name of the pad(s) to be configured.
-
-Optional pin configuration properties:
-  - low-power-enable: Configure the pad into power down mode
-  - low-power-disable: Configure the pad into active mode
-  - power-source: Must contain either TEGRA_IO_PAD_VOLTAGE_1V8
-    or TEGRA_IO_PAD_VOLTAGE_3V3 to select between signaling voltages.
-    The values are defined in
-    include/dt-bindings/pinctrl/pinctrl-tegra-io-pad.h.
-
-Note: The power state can be configured on all of the Tegra124 and
-      Tegra132 pads. None of the Tegra124 or Tegra132 pads support
-      signaling voltage switching.
-
-Note: All of the listed Tegra210 pads except pex-cntrl support power
-      state configuration. Signaling voltage switching is supported on
-      following Tegra210 pads: audio, audio-hv, cam, dbg, dmic, gpio,
-      pex-cntrl, sdmmc1, sdmmc3, spi, spi-hv, and uart.
-
-Pad configuration state example:
-	pmc: pmc@7000e400 {
-		compatible = "nvidia,tegra210-pmc";
-		reg = <0x0 0x7000e400 0x0 0x400>;
-		clocks = <&tegra_car TEGRA210_CLK_PCLK>, <&clk32k_in>;

-ARM Versatile Express boards family
------------------------------------
-
-ARM's Versatile Express platform consists of a motherboard and one
-or more daughterboards (tiles). The motherboard provides a set of
-peripherals. Processor and RAM "live" on the tiles.
-
-The motherboard and each core tile should be described by a separate
-Device Tree source file, with the tile's description including
-the motherboard file using a /include/ directive. As the motherboard
-can be initialized in one of two different configurations ("memory
-maps"), care must be taken to include the correct one.
-
-
-Root node
----------
-
-Required properties in the root node:
-- compatible value:
-	compatible = "arm,vexpress,<model>", "arm,vexpress";
-  where <model> is the full tile model name (as used in the tile's
-    Technical Reference Manual), eg.:
-    - for Coretile Express A5x2 (V2P-CA5s):
-	compatible = "arm,vexpress,v2p-ca5s", "arm,vexpress";
-    - for Coretile Express A9x4 (V2P-CA9):
-	compatible = "arm,vexpress,v2p-ca9", "arm,vexpress";
-  If a tile comes in several variants or can be used in more then one
-  configuration, the compatible value should be:
-	compatible = "arm,vexpress,<model>,<variant>", \
-				"arm,vexpress,<model>", "arm,vexpress";
-  eg:
-    - Coretile Express A15x2 (V2P-CA15) with Tech Chip 1:
-	compatible = "arm,vexpress,v2p-ca15,tc1", \
-				"arm,vexpress,v2p-ca15", "arm,vexpress";
-    - LogicTile Express 13MG (V2F-2XV6) running Cortex-A7 (3 cores) SMM:
-	compatible = "arm,vexpress,v2f-2xv6,ca7x3", \
-				"arm,vexpress,v2f-2xv6", "arm,vexpress";
-
-Optional properties in the root node:
-- tile model name (use name from the tile's Technical Reference
-  Manual, eg. "V2P-CA5s")
-	model = "<model>";
-- tile's HBI number (unique ARM's board model ID, visible on the
-  PCB's silkscreen) in hexadecimal transcription:
-	arm,hbi = <0xhbi>
-  eg:
-  - for Coretile Express A5x2 (V2P-CA5s) HBI-0191:
-	arm,hbi = <0x191>;
-  - Coretile Express A9x4 (V2P-CA9) HBI-0225:
-	arm,hbi = <0x225>;
-
-
-CPU nodes
----------
-
-Top-level standard "cpus" node is required. It must contain a node
-with device_type = "cpu" property for every available core, eg.:
-
-	cpus {
-		#address-cells = <1>;
-		#size-cells = <0>;
-
-		cpu@0 {
-			device_type = "cpu";
-			compatible = "arm,cortex-a5";
-			reg = <0>;
-		};
-	};
-
-
-Configuration infrastructure
-----------------------------
-
-The platform has an elaborated configuration system, consisting of
-microcontrollers residing on the mother- and daughterboards known
-as Motherboard/Daughterboard Configuration Controller (MCC and DCC).
-The controllers are responsible for the platform initialization
-(reset generation, flash programming, FPGA bitfiles loading etc.)
-but also control clock generators, voltage regulators, gather
-environmental data like temperature, power consumption etc. Even
-the video output switch (FPGA) is controlled that way.
-
-The controllers are not mapped into normal memory address space
-and must be accessed through bridges - other devices capable
-of generating transactions on the configuration bus.
-
-The nodes describing configuration controllers must define
-the following properties:
-- compatible value:
-	compatible = "arm,vexpress,config-bus";
-- bridge phandle:
-	arm,vexpress,config-bridge = <phandle>;
-and children describing available functions.
-
-
-Platform topology
------------------
-
-As Versatile Express can be configured in number of physically
-different setups, the device tree should describe platform topology.
-Root node and main motherboard node must define the following
-property, describing physical location of the children nodes:
-- site number:
-	arm,vexpress,site = <number>;
-  where 0 means motherboard, 1 or 2 are daugtherboard sites,
-  0xf means "master" site (site containing main CPU tile)
-- when daughterboards are stacked on one site, their position
-  in the stack be be described with:

-- when describing tiles consisting more than one DCC, its number

-

-
-Motherboard
------------
-
-The motherboard description file provides a single "motherboard" node
-using 2 address cells corresponding to the Static Memory Bus used
-between the motherboard and the tile. The first cell defines the Chip
-Select (CS) line number, the second cell address offset within the CS.
-All interrupt lines between the motherboard and the tile are active
-high and are described using single cell.
-
-Optional properties of the "motherboard" node:
-- motherboard's memory map variant:
-	arm,v2m-memory-map = "<name>";
-  where name is one of:
-  - "rs1" - for RS1 map (i.a. peripherals on CS3); this map is also
-            referred to as "ARM Cortex-A Series memory map":
-	arm,v2m-memory-map = "rs1";
-  When this property is missing, the motherboard is using the original
-  memory map (also known as the "Legacy memory map", primarily used
-  with the original CoreTile Express A9x4) with peripherals on CS7.
-
-Motherboard .dtsi files provide a set of labelled peripherals that
-can be used to obtain required phandle in the tile's "aliases" node:
-- UARTs, note that the numbers correspond to the physical connectors
-  on the motherboard's back panel:
-	v2m_serial0, v2m_serial1, v2m_serial2 and v2m_serial3
-- I2C controllers:
-	v2m_i2c_dvi and v2m_i2c_pcie
-- SP804 timers:
-	v2m_timer01 and v2m_timer23
-
-The tile description should define a "smb" node, describing the
-Static Memory Bus between the tile and motherboard. It must define
-the following properties:
-- "simple-bus" compatible value (to ensure creation of the children)
-	compatible = "simple-bus";
-- mapping of the SMB CS/offset addresses into main address space:
-	#address-cells = <2>;
-	#size-cells = <1>;
-	ranges = <...>;
-- interrupts mapping:
-	#interrupt-cells = <1>;
-	interrupt-map-mask = <0 0 63>;
-	interrupt-map = <...>;

+title: ARM System Controller ICST Clocks
+
+maintainers:
+  - Linus Walleij <linusw@kernel.org>
+
+description: |
+  The ICS525 and ICS307 oscillators are produced by Integrated
+  Devices Technology (IDT). ARM integrated these oscillators deeply into their
+  reference designs by adding special control registers that manage such
+  oscillators to their system controllers.
+
+  The various ARM system controllers contain logic to serialize and initialize
+  an ICST clock request after a write to the 32 bit register at an offset
+  into the system controller. Furthermore, to even be able to alter one of
+  these frequencies, the system controller must first be unlocked by
+  writing a special token to another offset in the system controller.
+
+  Some ARM hardware contain special versions of the serial interface that only
+  connects the low 8 bits of the VDW (missing one bit), hard-wires RDW to
+  different values and sometimes also hard-wires the output divider. They
+  therefore have special compatible strings as per this table (the OD value is
+  the value on the pins, not the resulting output divider).
+
+  In the core modules and logic tiles, the ICST is a configurable clock fed
+  from a 24 MHz clock on the motherboard (usually the main crystal) used for
+  generating e.g. video clocks. It is located on the core module and there is
+  only one of these. This clock node must be a subnode of the core module.
+

-Clock bindings for ARM Integrator and Versatile Core Module clocks
-
-Auxiliary Oscillator Clock
-
-This is a configurable clock fed from a 24 MHz chrystal,
-used for generating e.g. video clocks. It is located on the
-core module and there is only one of these.
-
-This clock node *must* be a subnode of the core module, since
-it obtains the base address for it's address range from its
-parent node.
-
-
-Required properties:
-- compatible: must be "arm,integrator-cm-auxosc" or "arm,versatile-cm-auxosc"
-- #clock-cells: must be <0>
-
-Optional properties:
-- clocks: parent clock(s)
-
-Example:
-
-core-module@10000000 {
-	xtal24mhz: xtal24mhz@24M {
-		#clock-cells = <0>;
-		compatible = "fixed-clock";
-		clock-frequency = <24000000>;

-	auxosc: cm_aux_osc@25M {
-		#clock-cells = <0>;
-		compatible = "arm,integrator-cm-auxosc";

-ARM System Controller ICST clocks
-
-The ICS525 and ICS307 oscillators are produced by Integrated Devices
-Technology (IDT). ARM integrated these oscillators deeply into their
-reference designs by adding special control registers that manage such
-oscillators to their system controllers.
-
-The various ARM system controllers contain logic to serialize and initialize
-an ICST clock request after a write to the 32 bit register at an offset
-into the system controller. Furthermore, to even be able to alter one of
-these frequencies, the system controller must first be unlocked by
-writing a special token to another offset in the system controller.
-
-Some ARM hardware contain special versions of the serial interface that only
-connects the low 8 bits of the VDW (missing one bit), hardwires RDW to
-different values and sometimes also hardwire the output divider. They
-therefore have special compatible strings as per this table (the OD value is
-the value on the pins, not the resulting output divider):
-
-Hardware variant:        RDW     OD          VDW

-- vco-offset: the offset address into the system controller where the

-* Marvell MMP2 Clock Controller
-
-The MMP2 clock subsystem generates and supplies clock to various
-controllers within the MMP2 SoC.
-
-Required Properties:
-
-- compatible: should be one of the following.
-  - "marvell,mmp2-clock" - controller compatible with MMP2 SoC.
-
-- reg: physical base address of the clock subsystem and length of memory mapped
-  region. There are 3 places in SOC has clock control logic:
-  "mpmu", "apmu", "apbc". So three reg spaces need to be defined.
-
-- #clock-cells: should be 1.
-- #reset-cells: should be 1.
-
-Each clock is assigned an identifier and client nodes use this identifier
-to specify the clock which they consume.
-
-All these identifiers could be found in <dt-bindings/clock/marvell,mmp2.h>.

-and MSSR (Module Standby and Software Reset) blocks are intimately connected,
-and share the same register block.
-
-They provide the following functionalities:
-  - The CPG block generates various core clocks,
-  - The MSSR block provides two functions:
-      1. Module Standby, providing a Clock Domain to control the clock supply
-	 to individual SoC devices,
-      2. Reset Control, to perform a software reset of individual SoC devices.

-USB Connector
-=============
-
-A USB connector node represents a physical USB connector. It should be
-a child of a USB interface controller.
-
-Required properties:
-- compatible: describes type of the connector, must be one of:
-    "usb-a-connector",
-    "usb-b-connector",
-    "usb-c-connector".
-
-Optional properties:
-- label: symbolic name for the connector,
-- type: size of the connector, should be specified in case of USB-A, USB-B
-  non-fullsize connectors: "mini", "micro".
-- self-powered: Set this property if the usb device that has its own power
-  source.
-
-Optional properties for usb-b-connector:
-- id-gpios: an input gpio for USB ID pin.
-- vbus-gpios: an input gpio for USB VBUS pin, used to detect presence of
-  VBUS 5V.
-  see gpio/gpio.txt.
-- vbus-supply: a phandle to the regulator for USB VBUS if needed when host
-  mode or dual role mode is supported.
-  Particularly, if use an output GPIO to control a VBUS regulator, should
-  model it as a regulator.
-  see regulator/fixed-regulator.yaml
-- pinctrl-names : a pinctrl state named "default" is optional
-- pinctrl-0 : pin control group
-  see pinctrl/pinctrl-bindings.txt
-
-Optional properties for usb-c-connector:
-- power-role: should be one of "source", "sink" or "dual"(DRP) if typec
-  connector has power support.
-- try-power-role: preferred power role if "dual"(DRP) can support Try.SNK
-  or Try.SRC, should be "sink" for Try.SNK or "source" for Try.SRC.
-- data-role: should be one of "host", "device", "dual"(DRD) if typec
-  connector supports USB data.
-
-Required properties for usb-c-connector with power delivery support:
-- source-pdos: An array of u32 with each entry providing supported power
-  source data object(PDO), the detailed bit definitions of PDO can be found
-  in "Universal Serial Bus Power Delivery Specification" chapter 6.4.1.2
-  Source_Capabilities Message, the order of each entry(PDO) should follow
-  the PD spec chapter 6.4.1. Required for power source and power dual role.
-  User can specify the source PDO array via PDO_FIXED/BATT/VAR/PPS_APDO()
-  defined in dt-bindings/usb/pd.h.
-- sink-pdos: An array of u32 with each entry providing supported power
-  sink data object(PDO), the detailed bit definitions of PDO can be found
-  in "Universal Serial Bus Power Delivery Specification" chapter 6.4.1.3
-  Sink Capabilities Message, the order of each entry(PDO) should follow
-  the PD spec chapter 6.4.1. Required for power sink and power dual role.
-  User can specify the sink PDO array via PDO_FIXED/BATT/VAR/PPS_APDO() defined
-  in dt-bindings/usb/pd.h.
-- op-sink-microwatt: Sink required operating power in microwatt, if source
-  can't offer the power, Capability Mismatch is set. Required for power
-  sink and power dual role.
-
-Required nodes:
-- any data bus to the connector should be modeled using the OF graph bindings
-  specified in bindings/graph.txt, unless the bus is between parent node and
-  the connector. Since single connector can have multiple data buses every bus
-  has assigned OF graph port number as follows:
-    0: High Speed (HS), present in all connectors,
-    1: Super Speed (SS), present in SS capable connectors,
-    2: Sideband use (SBU), present in USB-C.
-
-Examples
---------
-

-Vivante GPU core devices
-========================
-
-Required properties:
-- compatible: Should be "vivante,gc"
-  A more specific compatible is not needed, as the cores contain chip
-  identification registers at fixed locations, which provide all the
-  necessary information to the driver.
-- reg: should be register base and length as documented in the
-  datasheet
-- interrupts: Should contain the cores interrupt line
-- clocks: should contain one clock for entry in clock-names
-  see Documentation/devicetree/bindings/clock/clock-bindings.txt
-- clock-names:
-   - "bus":    AXI/master interface clock
-   - "reg":    AHB/slave interface clock
-               (only required if GPU can gate slave interface independently)
-   - "core":   GPU core clock
-   - "shader": Shader clock (only required if GPU has feature PIPE_3D)
-
-Optional properties:
-- power-domains: a power domain consumer specifier according to
-  Documentation/devicetree/bindings/power/power_domain.txt
-
-example:
-
-gpu_3d: gpu@130000 {
-	compatible = "vivante,gc";
-	reg = <0x00130000 0x4000>;
-	interrupts = <0 9 IRQ_TYPE_LEVEL_HIGH>;

-display-timing bindings
-=======================
-
-display-timings node
---------------------
-
-required properties:
- - none
-
-optional properties:
- - native-mode: The native mode for the display, in case multiple modes are
-		provided. When omitted, assume the first node is the native.
-
-timing subnode
---------------
-
-required properties:
- - hactive, vactive: display resolution
- - hfront-porch, hback-porch, hsync-len: horizontal display timing parameters
-   in pixels
-   vfront-porch, vback-porch, vsync-len: vertical display timing parameters in
-   lines
- - clock-frequency: display clock in Hz
-
-optional properties:
- - hsync-active: hsync pulse is active low/high/ignored
- - vsync-active: vsync pulse is active low/high/ignored
- - de-active: data-enable pulse is active low/high/ignored
- - pixelclk-active: with
-			- active high = drive pixel data on rising edge/
-					sample data on falling edge
-			- active low  = drive pixel data on falling edge/
-					sample data on rising edge
-			- ignored     = ignored
- - syncclk-active: with
-			- active high = drive sync on rising edge/
-					sample sync on falling edge of pixel
-					clock
-			- active low  = drive sync on falling edge/
-					sample sync on rising edge of pixel
-					clock
-			- omitted     = same configuration as pixelclk-active
- - interlaced (bool): boolean to enable interlaced mode
- - doublescan (bool): boolean to enable doublescan mode
- - doubleclk (bool): boolean to enable doubleclock mode
-
-All the optional properties that are not bool follow the following logic:
-    <1>: high active
-    <0>: low active
-    omitted: not used on hardware
-
-There are different ways of describing the capabilities of a display. The
-devicetree representation corresponds to the one commonly found in datasheets
-for displays. If a display supports multiple signal timings, the native-mode
-can be specified.
-
-The parameters are defined as:

-
-Note: In addition to being used as subnode(s) of display-timings, the timing
-      subnode may also be used on its own. This is appropriate if only one mode
-      need be conveyed. In this case, the node should be named 'panel-timing'.
-
-
-Example:
-
-	display-timings {
-		native-mode = <&timing0>;
-		timing0: 1080p24 {
-			/* 1920x1080p24 */
-			clock-frequency = <52000000>;
-			hactive = <1920>;
-			vactive = <1080>;
-			hfront-porch = <25>;
-			hback-porch = <25>;
-			hsync-len = <25>;
-			vback-porch = <2>;
-			vfront-porch = <2>;
-			vsync-len = <2>;
-			hsync-active = <1>;
-		};
-	};
-
-Every required property also supports the use of ranges, so the commonly used
-datasheet description with minimum, typical and maximum values can be used.
-
-Example:
-
-	timing1: timing {
-		/* 1920x1080p24 */
-		clock-frequency = <148500000>;
-		hactive = <1920>;
-		vactive = <1080>;
-		hsync-len = <0 44 60>;
-		hfront-porch = <80 88 95>;
-		hback-porch = <100 148 160>;
-		vfront-porch = <0 4 6>;
-		vback-porch = <0 36 50>;
-		vsync-len = <0 5 6>;
-	};

+
+description: |
+  This binding file is a collection of the DSI panels that
+  requires only a single power-supply.
+  There are optionally a backlight and an enable GPIO.
+  The panel may use an OF graph binding for the association to the display,
+  or it may be a direct child node of the display.
+
+  If the panel is more advanced a dedicated binding file is required.

+  node will always be a child of an FSI CFAM node; see fsi.txt for details on
+  FSI slave and CFAM nodes. This FSI2SPI engine provides access to a number of

-UniPhier GPIO controller

-Required properties:
-- compatible: Should be "socionext,uniphier-gpio".
-- reg: Specifies offset and length of the register set for the device.
-- gpio-controller: Marks the device node as a GPIO controller.
-- #gpio-cells: Should be 2.  The first cell is the pin number and the second
-  cell is used to specify optional parameters.
-- interrupt-controller: Marks the device node as an interrupt controller.
-- #interrupt-cells: Should be 2.  The first cell defines the interrupt number.
-  The second cell bits[3:0] is used to specify trigger type as follows:
-    1 = low-to-high edge triggered
-    2 = high-to-low edge triggered
-    4 = active high level-sensitive
-    8 = active low level-sensitive
-  Valid combinations are 1, 2, 3, 4, 8.
-- ngpios: Specifies the number of GPIO lines.
-- gpio-ranges: Mapping to pin controller pins (as described in gpio.txt)
-- socionext,interrupt-ranges: Specifies an interrupt number mapping between
-  this GPIO controller and its interrupt parent, in the form of arbitrary
-  number of <child-interrupt-base parent-interrupt-base length> triplets.
-
-Optional properties:
-- gpio-ranges-group-names: Used for named gpio ranges (as described in gpio.txt)
-
-Example:
-	gpio: gpio@55000000 {
-		compatible = "socionext,uniphier-gpio";
-		reg = <0x55000000 0x200>;
-		interrupt-parent = <&aidet>;
-		interrupt-controller;
-		#interrupt-cells = <2>;
-		gpio-controller;
-		#gpio-cells = <2>;
-		gpio-ranges = <&pinctrl 0 0 0>;
-		gpio-ranges-group-names = "gpio_range";
-		ngpios = <248>;
-		socionext,interrupt-ranges = <0 48 16>, <16 154 5>, <21 217 3>;
-	};
-
-Consumer Example:
-
-	sdhci0_pwrseq {
-		compatible = "mmc-pwrseq-emmc";
-		reset-gpios = <&gpio UNIPHIER_GPIO_PORT(29, 4) GPIO_ACTIVE_LOW>;
-	};
-
-Please note UNIPHIER_GPIO_PORT(29, 4) represents PORT294 in the SoC document.
-Unfortunately, only the one's place is octal in the port numbering.  (That is,
-PORT 8, 9, 18, 19, 28, 29, ... are missing.)  UNIPHIER_GPIO_PORT() is a helper
-macro to calculate 29 * 8 + 4.

-
-Required on RK3066, RK3188 :
-
- - rockchip,grf : the phandle of the syscon node for the general register
-		  file (GRF)
- - on those SoCs an alias with the correct I2C bus ID (bit offset in the GRF)

- - clock-frequency : SCL frequency to use (in Hz). If omitted, 100kHz is used.
- - i2c-scl-rising-time-ns : Number of nanoseconds the SCL signal takes to rise
-	(t(r) in I2C specification). If not specified this is assumed to be
-	the maximum the specification allows(1000 ns for Standard-mode,
-	300 ns for Fast-mode) which might cause slightly slower communication.
- - i2c-scl-falling-time-ns : Number of nanoseconds the SCL signal takes to fall
-	(t(f) in the I2C specification). If not specified this is assumed to
-	be the maximum the specification allows (300 ns) which might cause

- - i2c-sda-falling-time-ns : Number of nanoseconds the SDA signal takes to fall

-STMicroelectronics STM32 ADC device driver
-
-STM32 ADC is a successive approximation analog-to-digital converter.
-It has several multiplexed input channels. Conversions can be performed
-in single, continuous, scan or discontinuous mode. Result of the ADC is
-stored in a left-aligned or right-aligned 32-bit data register.
-Conversions can be launched in software or using hardware triggers.
-
-The analog watchdog feature allows the application to detect if the input
-voltage goes beyond the user-defined, higher or lower thresholds.
-
-Each STM32 ADC block can have up to 3 ADC instances.
-
-Each instance supports two contexts to manage conversions, each one has its
-own configurable sequence and trigger:
-- regular conversion can be done in sequence, running in background
-- injected conversions have higher priority, and so have the ability to
-  interrupt regular conversion sequence (either triggered in SW or HW).
-  Regular sequence is resumed, in case it has been interrupted.
-
-Contents of a stm32 adc root node:
------------------------------------
-Required properties:
-- compatible: Should be one of:
-  "st,stm32f4-adc-core"
-  "st,stm32h7-adc-core"
-  "st,stm32mp1-adc-core"
-- reg: Offset and length of the ADC block register set.
-- interrupts: One or more interrupts for ADC block. Some parts like stm32f4
-  and stm32h7 share a common ADC interrupt line. stm32mp1 has two separate
-  interrupt lines, one for each ADC within ADC block.
-- clocks: Core can use up to two clocks, depending on part used:
-  - "adc" clock: for the analog circuitry, common to all ADCs.
-    It's required on stm32f4.
-    It's optional on stm32h7.
-  - "bus" clock: for registers access, common to all ADCs.
-    It's not present on stm32f4.
-    It's required on stm32h7.
-- clock-names: Must be "adc" and/or "bus" depending on part used.
-- interrupt-controller: Identifies the controller node as interrupt-parent
-- vdda-supply: Phandle to the vdda input analog voltage.
-- vref-supply: Phandle to the vref input analog reference voltage.
-- #interrupt-cells = <1>;
-- #address-cells = <1>;
-- #size-cells = <0>;
-
-Optional properties:
-- A pinctrl state named "default" for each ADC channel may be defined to set
-  inX ADC pins in mode of operation for analog input on external pin.
-- booster-supply: Phandle to the embedded booster regulator that can be used
-  to supply ADC analog input switches on stm32h7 and stm32mp1.
-- vdd-supply: Phandle to the vdd input voltage. It can be used to supply ADC
-  analog input switches on stm32mp1.
-- st,syscfg: Phandle to system configuration controller. It can be used to
-  control the analog circuitry on stm32mp1.
-- st,max-clk-rate-hz: Allow to specify desired max clock rate used by analog
-  circuitry.
-
-Contents of a stm32 adc child node:
------------------------------------
-An ADC block node should contain at least one subnode, representing an
-ADC instance available on the machine.
-
-Required properties:
-- compatible: Should be one of:
-  "st,stm32f4-adc"
-  "st,stm32h7-adc"
-  "st,stm32mp1-adc"
-- reg: Offset of ADC instance in ADC block (e.g. may be 0x0, 0x100, 0x200).
-- clocks: Input clock private to this ADC instance. It's required only on
-  stm32f4, that has per instance clock input for registers access.
-- interrupts: IRQ Line for the ADC (e.g. may be 0 for adc@0, 1 for adc@100 or
-  2 for adc@200).
-- st,adc-channels: List of single-ended channels muxed for this ADC.
-  It can have up to 16 channels on stm32f4 or 20 channels on stm32h7, numbered
-  from 0 to 15 or 19 (resp. for in0..in15 or in0..in19).
-- st,adc-diff-channels: List of differential channels muxed for this ADC.
-  Depending on part used, some channels can be configured as differential
-  instead of single-ended (e.g. stm32h7). List here positive and negative
-  inputs pairs as <vinp vinn>, <vinp vinn>,... vinp and vinn are numbered
-  from 0 to 19 on stm32h7)
-  Note: At least one of "st,adc-channels" or "st,adc-diff-channels" is required.
-  Both properties can be used together. Some channels can be used as
-  single-ended and some other ones as differential (mixed). But channels
-  can't be configured both as single-ended and differential (invalid).
-- #io-channel-cells = <1>: See the IIO bindings section "IIO consumers" in
-  Documentation/devicetree/bindings/iio/iio-bindings.txt
-
-Optional properties:
-- dmas: Phandle to dma channel for this ADC instance.
-  See ../../dma/dma.txt for details.
-- dma-names: Must be "rx" when dmas property is being used.
-- assigned-resolution-bits: Resolution (bits) to use for conversions. Must
-  match device available resolutions:
-  * can be 6, 8, 10 or 12 on stm32f4
-  * can be 8, 10, 12, 14 or 16 on stm32h7
-  Default is maximum resolution if unset.
-- st,min-sample-time-nsecs: Minimum sampling time in nanoseconds.
-  Depending on hardware (board) e.g. high/low analog input source impedance,
-  fine tune of ADC sampling time may be recommended.
-  This can be either one value or an array that matches 'st,adc-channels' list,
-  to set sample time resp. for all channels, or independently for each channel.
-
-Example:
-	adc: adc@40012000 {
-		compatible = "st,stm32f4-adc-core";
-		reg = <0x40012000 0x400>;
-		interrupts = <18>;
-		clocks = <&rcc 0 168>;
-		clock-names = "adc";
-		vref-supply = <&reg_vref>;
-		interrupt-controller;
-		pinctrl-names = "default";
-		pinctrl-0 = <&adc3_in8_pin>;
-
-		#interrupt-cells = <1>;
-		#address-cells = <1>;
-		#size-cells = <0>;
-
-		adc@0 {
-			compatible = "st,stm32f4-adc";
-			#io-channel-cells = <1>;
-			reg = <0x0>;
-			clocks = <&rcc 0 168>;
-			interrupt-parent = <&adc>;
-			interrupts = <0>;
-			st,adc-channels = <8>;
-			dmas = <&dma2 0 0 0x400 0x0>;
-			dma-names = "rx";
-			assigned-resolution-bits = <8>;
-		};
-		...
-		other adc child nodes follow...
-	};
-
-Example to setup:
-- channel 1 as single-ended
-- channels 2 & 3 as differential (with resp. 6 & 7 negative inputs)
-
-	adc: adc@40022000 {
-		compatible = "st,stm32h7-adc-core";
-		...
-		adc1: adc@0 {
-			compatible = "st,stm32h7-adc";
-			...
-			st,adc-channels = <1>;
-			st,adc-diff-channels = <2 6>, <3 7>;
-		};
-	};

+description: |
+  The Azoteq IQS620A, IQS621, IQS622, IQS624 and IQS625 multi-function sensors
+  feature a variety of self-capacitive, mutual-inductive and Hall-effect sens-
+  ing capabilities that can facilitate a variety of contactless key and switch
+  applications.
+
+  These functions are collectively represented by a "keys" child node from the
+  parent MFD driver. See Documentation/devicetree/bindings/mfd/iqs62x.yaml for
+  further details and examples. Sensor hardware configuration (self-capacitive
+  vs. mutual-inductive, etc.) is selected based on the device's firmware.

-FocalTech EDT-FT5x06 Polytouch driver
-=====================================
-
-There are 5 variants of the chip for various touch panel sizes
-FT5206GE1  2.8" .. 3.8"
-FT5306DE4  4.3" .. 7"
-FT5406EE8  7"   .. 8.9"
-FT5506EEG  7"   .. 8.9"
-FT5726NEI  5.7” .. 11.6"
-
-The software interface is identical for all those chips, so that
-currently there is no need for the driver to distinguish between the
-different chips. Nevertheless distinct compatible strings are used so
-that a distinction can be added if necessary without changing the DT
-bindings.
-
-
-Required properties:
- - compatible:  "edt,edt-ft5206"

-Optional properties:
- - reset-gpios: GPIO specification for the RESET input
- - wake-gpios:  GPIO specification for the WAKE input
- - vcc-supply:  Regulator that supplies the touchscreen
-
- - pinctrl-names: should be "default"
- - pinctrl-0:   a phandle pointing to the pin settings for the
-                control gpios
-
- - wakeup-source: If present the device will act as wakeup-source
-
- - threshold:   allows setting the "click"-threshold in the range
-                from 0 to 80.
-
- - gain:        allows setting the sensitivity in the range from 0 to
-                31. Note that lower values indicate higher
-                sensitivity.
-
- - offset:      allows setting the edge compensation in the range from
-                0 to 31.
-
- - offset-x:    Same as offset, but applies only to the horizontal position.
-                Range from 0 to 80, only supported by evervision,ev-ft5726

+description: |-
+  The Sony imx219 is a 1/4.0-inch CMOS active pixel digital image sensor
+  with an active array size of 3280H x 2464V. It is programmable through
+  I2C interface. The I2C address is fixed to 0x10 as per sensor data sheet.
+  Image data is sent through MIPI CSI-2, which is configured as either 2 or
+  4 data lanes.

-Renesas R-Car Video Input driver (rcar_vin)
--------------------------------------------
-
-The rcar_vin device provides video input capabilities for the Renesas R-Car
-family of devices.
-
-Each VIN instance has a single parallel input that supports RGB and YUV video,
-with both external synchronization and BT.656 synchronization for the latter.
-Depending on the instance the VIN input is connected to external SoC pins, or
-on Gen3 and RZ/G2 platforms to a CSI-2 receiver.
-
- - compatible: Must be one or more of the following
-   - "renesas,vin-r8a7743" for the R8A7743 device
-   - "renesas,vin-r8a7744" for the R8A7744 device
-   - "renesas,vin-r8a7745" for the R8A7745 device
-   - "renesas,vin-r8a77470" for the R8A77470 device
-   - "renesas,vin-r8a774a1" for the R8A774A1 device
-   - "renesas,vin-r8a774b1" for the R8A774B1 device
-   - "renesas,vin-r8a774c0" for the R8A774C0 device
-   - "renesas,vin-r8a7778" for the R8A7778 device
-   - "renesas,vin-r8a7779" for the R8A7779 device
-   - "renesas,vin-r8a7790" for the R8A7790 device
-   - "renesas,vin-r8a7791" for the R8A7791 device
-   - "renesas,vin-r8a7792" for the R8A7792 device
-   - "renesas,vin-r8a7793" for the R8A7793 device
-   - "renesas,vin-r8a7794" for the R8A7794 device
-   - "renesas,vin-r8a7795" for the R8A7795 device
-   - "renesas,vin-r8a7796" for the R8A7796 device
-   - "renesas,vin-r8a77965" for the R8A77965 device
-   - "renesas,vin-r8a77970" for the R8A77970 device
-   - "renesas,vin-r8a77980" for the R8A77980 device
-   - "renesas,vin-r8a77990" for the R8A77990 device
-   - "renesas,vin-r8a77995" for the R8A77995 device
-   - "renesas,rcar-gen2-vin" for a generic R-Car Gen2 or RZ/G1 compatible
-     device.
-
-   When compatible with the generic version nodes must list the
-   SoC-specific version corresponding to the platform first
-   followed by the generic version.
-
- - reg: the register base and size for the device registers
- - interrupts: the interrupt for the device
- - clocks: Reference to the parent clock
-
-The per-board settings for Gen2 and RZ/G1 platforms:
-
-- port - sub-node describing a single endpoint connected to the VIN
-  from external SoC pins as described in video-interfaces.txt[1].
-  Only the first one will be considered as each vin interface has one
-  input port.
-
-  - Optional properties for endpoint nodes:
-    - hsync-active: see [1] for description. Default is active high.
-    - vsync-active: see [1] for description. Default is active high.
-      If both HSYNC and VSYNC polarities are not specified, embedded
-      synchronization is selected.
-    - field-active-even: see [1] for description. Default is active high.
-    - bus-width: see [1] for description. The selected bus width depends on
-      the SoC type and selected input image format.
-      Valid values are: 8, 10, 12, 16, 24 and 32.
-    - data-shift: see [1] for description. Valid values are 0 and 8.
-    - data-enable-active: polarity of CLKENB signal, see [1] for
-      description. Default is active high.
-
-The per-board settings for Gen3 and RZ/G2 platforms:
-
-Gen3 and RZ/G2 platforms can support both a single connected parallel input
-source from external SoC pins (port@0) and/or multiple parallel input sources
-from local SoC CSI-2 receivers (port@1) depending on SoC.
-
-- renesas,id - ID number of the VIN, VINx in the documentation.
-- ports
-    - port@0 - sub-node describing a single endpoint connected to the VIN
-      from external SoC pins as described in video-interfaces.txt[1].
-      Describing more than one endpoint in port@0 is invalid. Only VIN
-      instances that are connected to external pins should have port@0.
-
-      Endpoint nodes of port@0 support the optional properties listed in
-      the Gen2 per-board settings description.
-
-    - port@1 - sub-nodes describing one or more endpoints connected to
-      the VIN from local SoC CSI-2 receivers. The endpoint numbers must
-      use the following schema.
-
-        - endpoint@0 - sub-node describing the endpoint connected to CSI20
-        - endpoint@1 - sub-node describing the endpoint connected to CSI21
-        - endpoint@2 - sub-node describing the endpoint connected to CSI40
-        - endpoint@3 - sub-node describing the endpoint connected to CSI41
-
-      Endpoint nodes of port@1 do not support any optional endpoint property.

-* ROHM BD71837 and BD71847 Power Management Integrated Circuit bindings
-
-BD71837MWV and BD71847MWV are programmable Power Management ICs for powering
-single-core, dual-core, and quad-core SoCs such as NXP-i.MX 8M. They are
-optimized for low BOM cost and compact solution footprint. BD71837MWV
-integrates 8 Buck regulators and 7 LDOs. BD71847MWV contains 6 Buck regulators
-and 6 LDOs.
-
-Datasheet for BD71837 is available at:
-https://www.rohm.com/datasheet/BD71837MWV/bd71837mwv-e
-Datasheet for BD71847 is available at:
-https://www.rohm.com/datasheet/BD71847AMWV/bd71847amwv-e
-
-Required properties:
- - compatible		: Should be "rohm,bd71837" for bd71837
-				    "rohm,bd71847" for bd71847.
- - reg			: I2C slave address.
- - interrupt-parent	: Phandle to the parent interrupt controller.
- - interrupts		: The interrupt line the device is connected to.
- - clocks		: The parent clock connected to PMIC. If this is missing
-			  32768 KHz clock is assumed.
- - #clock-cells		: Should be 0.
- - regulators:		: List of child nodes that specify the regulators.
-			  Please see ../regulator/rohm,bd71837-regulator.txt
-
-Optional properties:
-- clock-output-names	: Should contain name for output clock.
-- rohm,reset-snvs-powered : Transfer BD718x7 to SNVS state at reset.
-
-The BD718x7 supports two different HW states as reset target states. States
-are called as SNVS and READY. At READY state all the PMIC power outputs go
-down and OTP is reload. At the SNVS state all other logic and external
-devices apart from the SNVS power domain are shut off. Please refer to NXP
-i.MX8 documentation for further information regarding SNVS state. When a
-reset is done via SNVS state the PMIC OTP data is not reload. This causes
-power outputs that have been under SW control to stay down when reset has
-switched power state to SNVS. If reset is done via READY state the power
-outputs will be returned to HW control by OTP loading. Thus the reset
-target state is set to READY by default. If SNVS state is used the boot
-crucial regulators must have the regulator-always-on and regulator-boot-on
-properties set in regulator node.
-
-- rohm,short-press-ms	: Short press duration in milliseconds
-- rohm,long-press-ms	: Long press duration in milliseconds
-
-Configure the "short press" and "long press" timers for the power button.
-Values are rounded to what hardware supports (500ms multiple for short and
-1000ms multiple for long). If these properties are not present the existing
-configuration (from bootloader or OTP) is not touched.

-
-	/* external oscillator node */

+description: |
+  BD71847AMWV and BD71850MWV are programmable Power Management ICs for powering
+  single-core,  dual-core, and quad-core SoCs such as NXP-i.MX 8M. It is
+  optimized for low BOM cost and compact solution footprint. BD71847MWV and
+  BD71850MWV integrate 6 Buck regulators and 6 LDOs.
+  Datasheets are available at

+# The BD71847 abd BD71850 support two different HW states as reset target
+# states. States are called as SNVS and READY. At READY state all the PMIC
+# power outputs go down and OTP is reload. At the SNVS state all other logic
+# and external devices apart from the SNVS power domain are shut off. Please
+# refer to NXP i.MX8 documentation for further information regarding SNVS
+# state. When a reset is done via SNVS state the PMIC OTP data is not reload.
+# This causes power outputs that have been under SW control to stay down when
+# reset has switched power state to SNVS. If reset is done via READY state the
+# power outputs will be returned to HW control by OTP loading. Thus the reset
+# target state is set to READY by default. If SNVS state is used the boot
+# crucial regulators must have the regulator-always-on and regulator-boot-on

+Macronix NANDs Device Tree Bindings
+-----------------------------------
+
+Macronix NANDs support randomizer operation for scrambling user data,
+which can be enabled with a SET_FEATURE. The penalty when using the
+randomizer are subpage accesses prohibited and more time period needed
+for program operation, i.e., tPROG 300us to 340us (randomizer enabled).
+Enabling the randomizer is a one time persistent and non reversible
+operation.
+
+For more high-reliability concern, if subpage write is not available
+with hardware ECC and not enabled at UBI level, then enabling the
+randomizer is recommended by default by adding a new specific property
+in children nodes.
+
+Required NAND chip properties in children mode:
+- randomizer enable: should be "mxic,enable-randomizer-otp"
+
+Example:
+
+	nand: nand-controller@unit-address {
+
+		nand@0 {
+			reg = <0>;
+			mxic,enable-randomizer-otp;
+		};
+	};

-Generic CAN transceiver Device Tree binding
-------------------------------
-
-CAN transceiver typically limits the max speed in standard CAN and CAN FD
-modes. Typically these limitations are static and the transceivers themselves
-provide no way to detect this limitation at runtime. For this situation,
-the "can-transceiver" node can be used.
-
-Required Properties:
- max-bitrate:	a positive non 0 value that determines the max
-		speed that CAN/CAN-FD can run. Any other value
-		will be ignored.
-
-Examples:
-
-Based on Texas Instrument's TCAN1042HGV CAN Transceiver
-
-m_can0 {
-	....
-	can-transceiver {
-		max-bitrate = <5000000>;

+Microchip Ocelot switch driver family
+=====================================
+
+Felix
+-----
+
+The VSC9959 core is currently the only switch supported by the driver, and is
+found in the NXP LS1028A. It is a PCI device, part of the larger ENETC root
+complex. As a result, the ethernet-switch node is a sub-node of the PCIe root
+complex node and its "reg" property conforms to the parent node bindings:
+
+* reg: Specifies PCIe Device Number and Function Number of the endpoint device,
+  in this case for the Ethernet L2Switch it is PF5 (of device 0, bus 0).
+
+It does not require a "compatible" string.
+
+The interrupt line is used to signal availability of PTP TX timestamps and for
+TSN frame preemption.
+
+For the external switch ports, depending on board configuration, "phy-mode" and
+"phy-handle" are populated by board specific device tree instances. Ports 4 and
+5 are fixed as internal ports in the NXP LS1028A instantiation.
+
+The CPU port property ("ethernet") configures the feature called "NPI port" in
+the Ocelot hardware core. The CPU port in Ocelot is a set of queues, which are
+connected, in the Node Processor Interface (NPI) mode, to an Ethernet port.
+By default, in fsl-ls1028a.dtsi, the NPI port is assigned to the internal
+2.5Gbps port@4, but can be moved to the 1Gbps port@5, depending on the specific
+use case.  Moving the NPI port to an external switch port is hardware possible,
+but there is no platform support for the Linux system on the LS1028A chip to
+operate as an entire slave DSA chip.  NPI functionality (and therefore DSA
+tagging) is supported on a single port at a time.
+
+Any port can be disabled (and in fsl-ls1028a.dtsi, they are indeed all disabled
+by default, and should be enabled on a per-board basis). But if any external
+switch port is enabled at all, the ENETC PF2 (enetc_port2) should be enabled as
+well, regardless of whether it is configured as the DSA master or not. This is
+because the Felix PHYLINK implementation accesses the MAC PCS registers, which
+in hardware truly belong to the ENETC port #2 and not to Felix.
+
+Supported PHY interface types (appropriate SerDes protocol setting changes are
+needed in the RCW binary):
+
+* phy_mode = "internal": on ports 4 and 5
+* phy_mode = "sgmii": on ports 0, 1, 2, 3
+* phy_mode = "qsgmii": on ports 0, 1, 2, 3
+* phy_mode = "usxgmii": on ports 0, 1, 2, 3
+* phy_mode = "2500base-x": on ports 0, 1, 2, 3
+

+PCI, refer to the following documents:

+description: |+
+  This controller is mounted on development boards for Marvell's Link Street
+  family of Ethernet switches. It allows you to configure the switch's registers
+  using the standard MDIO interface.
+
+  Since the device is connected over USB, there is no strict requirement of
+  having a device tree representation of the device. But in order to use it with
+  the mv88e6xxx driver, you need a device tree node in which to place the switch
+  definition.

+
+description:
+  This binding describes the Qualcomm IPA.  The IPA is capable of offloading
+  certain network processing tasks (e.g. filtering, routing, and NAT) from
+  the main processor.
+
+  The IPA sits between multiple independent "execution environments,"
+  including the Application Processor (AP) and the modem.  The IPA presents
+  a Generic Software Interface (GSI) to each execution environment.
+  The GSI is an integral part of the IPA, but it is logically isolated
+  and has a distinct interrupt and a separately-defined address space.
+
+  See also soc/qcom/qcom,smp2p.txt and interconnect/interconnect.txt.

+- reg: base addresses and lengths of the PCIe controller register blocks.
+  "csr_axi_slave": Bridge config registers
+  "config_axi_slave": PCIe controller registers
+- interrupts: A list of interrupt outputs of the controller. Must contain an

+- interrupt-names: It could include the following entries:
+  "intr": The interrupt that is asserted for controller interrupts
+  "aer": Asserted for aer interrupt when chip support the aer interrupt with
+	 none MSI/MSI-X/INTx mode,but there is interrupt line for aer.
+  "pme": Asserted for pme interrupt when chip support the pme interrupt with
+	 none MSI/MSI-X/INTx mode,but there is interrupt line for pme.
+- dma-coherent: Indicates that the hardware IP block can ensure the coherency
+  of the data transferred from/to the IP block. This can avoid the software
+  cache flush/invalid actions, and improve the performance significantly.
+- msi-parent : See the generic MSI binding described in

-ROCKCHIP USB2.0 PHY WITH INNO IP BLOCK
-
-Required properties (phy (parent) node):
- - compatible : should be one of the listed compatibles:
-	* "rockchip,px30-usb2phy"
-	* "rockchip,rk3228-usb2phy"
-	* "rockchip,rk3328-usb2phy"
-	* "rockchip,rk3366-usb2phy"
-	* "rockchip,rk3399-usb2phy"
-	* "rockchip,rv1108-usb2phy"
- - reg : the address offset of grf for usb-phy configuration.
- - #clock-cells : should be 0.
- - clock-output-names : specify the 480m output clock name.
-
-Optional properties:
- - clocks : phandle + phy specifier pair, for the input clock of phy.
- - clock-names : input clock name of phy, must be "phyclk".
- - assigned-clocks : phandle of usb 480m clock.
- - assigned-clock-parents : parent of usb 480m clock, select between
-		 usb-phy output 480m and xin24m.
-		 Refer to clk/clock-bindings.txt for generic clock
-		 consumer properties.
- - rockchip,usbgrf : phandle to the syscon managing the "usb general
-		 register files". When set driver will request its
-		 phandle as one companion-grf for some special SoCs
-		 (e.g RV1108).
- - extcon : phandle to the extcon device providing the cable state for
-		 the otg phy.
-
-Required nodes : a sub-node is required for each port the phy provides.
-		 The sub-node name is used to identify host or otg port,
-		 and shall be the following entries:
-	* "otg-port" : the name of otg port.
-	* "host-port" : the name of host port.
-
-Required properties (port (child) node):
- - #phy-cells : must be 0. See ./phy-bindings.txt for details.
- - interrupts : specify an interrupt for each entry in interrupt-names.
- - interrupt-names : a list which should be one of the following cases:
-	Regular case:
-	* "otg-id" : for the otg id interrupt.
-	* "otg-bvalid" : for the otg vbus interrupt.
-	* "linestate" : for the host/otg linestate interrupt.
-	Some SoCs use one interrupt with the above muxed together, so for these
-	* "otg-mux" : otg-port interrupt, which mux otg-id/otg-bvalid/linestate
-		to one.
-
-Optional properties:
- - phy-supply : phandle to a regulator that provides power to VBUS.
-		See ./phy-bindings.txt for details.

-
-Please refer to fsl,imx-pinctrl.txt and pinctrl-bindings.txt in this directory
-for common binding part and usage.
-
-Required properties:
-- compatible: "fsl,imx8mq-iomuxc"
-- reg: should contain the base physical address and size of the iomuxc
-  registers.
-
-Required properties in sub-nodes:
-- fsl,pins: each entry consists of 6 integers and represents the mux and config
-  setting for one pin.  The first 5 integers <mux_reg conf_reg input_reg mux_val
-  input_val> are specified using a PIN_FUNC_ID macro, which can be found in
-  imx8mq-pinfunc.h under device tree source folder.  The last integer CONFIG is
-  the pad setting value like pull-up on this pin.  Please refer to i.MX8M Quad
-  Reference Manual for detailed CONFIG settings.

+description: |
+  List of regulators provided by this controller. BD71847 regulators node
+  should be sub node of the BD71847 MFD node. See BD71847 MFD bindings at
+  Documentation/devicetree/bindings/mfd/rohm,bd71847-pmic.yaml
+  Regulator nodes should be named to BUCK_<number> and LDO_<number>. The
+  definition for each of these nodes is defined using the standard
+  binding for regulators at
+  Documentation/devicetree/bindings/regulator/regulator.txt.
+  Note that if BD71847 starts at RUN state you probably want to use
+  regulator-boot-on at least for BUCK5. LDO6 is supplied by it and it must
+  not be disabled by driver at startup. If BUCK5 is disabled at startup the
+  voltage monitoring for LDO5/LDO6 can cause PMIC to reset.
+
+#The valid names for BD71847 regulator nodes are:
+#BUCK1, BUCK2, BUCK3, BUCK4, BUCK5, BUCK6

+description:
+  The OMAP family of SoCs usually have one or more slave processor sub-systems
+  that are used to offload some of the processor-intensive tasks, or to manage
+  other hardware accelerators, for achieving various system level goals.
+
+  The processor cores in the sub-system are usually behind an IOMMU, and may
+  contain additional sub-modules like Internal RAM and/or ROMs, L1 and/or L2
+  caches, an Interrupt Controller, a Cache Controller etc.
+
+  The OMAP SoCs usually have a DSP processor sub-system and/or an IPU processor
+  sub-system. The DSP processor sub-system can contain any of the TI's C64x,
+  C66x or C67x family of DSP cores as the main execution unit. The IPU processor
+  sub-system usually contains either a Dual-Core Cortex-M3 or Dual-Core
+  Cortex-M4 processors.
+
+  Each remote processor sub-system is represented as a single DT node. Each node
+  has a number of required or optional properties that enable the OS running on
+  the host processor (MPU) to perform the device management of the remote
+  processor and to communicate with the remote processor. The various properties
+  can be classified as constant or variable. The constant properties are
+  dictated by the SoC and does not change from one board to another having the
+  same SoC. Examples of constant properties include 'iommus', 'reg'. The
+  variable properties are dictated by the system integration aspects such as
+  memory on the board, or configuration used within the corresponding firmware
+  image. Examples of variable properties include 'mboxes', 'memory-region',
+  'timers', 'watchdog-timers' etc.

+
+      This property is mandatory on remote processors requiring

-
-    When compatible with the generic version, nodes must list the
-    SoC-specific version corresponding to the platform first, followed by the
-    family-specific and/or generic versions.
-
-  - reg: Base address and length of the I/O registers used by the UART.
-  - interrupts: Must contain one or more interrupt-specifiers for the SCIx.
-                If a single interrupt is expressed, then all events are
-                multiplexed into this single interrupt.
-
-                If multiple interrupts are provided by the hardware, the order
-                in which the interrupts are listed must match order below. Note
-                that some HW interrupt events may be muxed together resulting
-                in duplicate entries.
-                The interrupt order is as follows:
-                  1. Error (ERI)
-                  2. Receive buffer full (RXI)
-                  3. Transmit buffer empty (TXI)
-                  4. Break (BRI)
-                  5. Data Ready (DRI)
-                  6. Transmit End (TEI)
-
-  - clocks: Must contain a phandle and clock-specifier pair for each entry
-    in clock-names.
-  - clock-names: Must contain "fck" for the SCIx UART functional clock.
-    Apart from the divided functional clock, there may be other possible
-    sources for the sampling clock, depending on SCIx variant.
-    On (H)SCI(F) and some SCIFA, an additional clock may be specified:
-      - "hsck" for the optional external clock input (on HSCIF),
-      - "sck" for the optional external clock input (on other variants).
-    On UARTs equipped with a Baud Rate Generator for External Clock (BRG)
-    (some SCIF and HSCIF), additional clocks may be specified:
-      - "brg_int" for the optional internal clock source for the frequency
-	divider (typically the (AXI or SHwy) bus clock),
-      - "scif_clk" for the optional external clock source for the frequency
-	divider (SCIF_CLK).
-
-Note: Each enabled SCIx UART may have an optional "serialN" alias in the
-"aliases" node.
-
-Optional properties:
-  - dmas: Must contain a list of two references to DMA specifiers, one for
-	  transmission, and one for reception.
-  - dma-names: Must contain a list of two DMA names, "tx" and "rx".
-  - {cts,dsr,dcd,rng,rts,dtr}-gpios: Specify GPIOs for modem lines, cfr. the
-    generic serial DT bindings in serial.txt.
-  - uart-has-rtscts: Indicates dedicated lines for RTS/CTS hardware flow
-    control, cfr. the generic serial DT bindings in serial.txt.
-
-Example:
-	aliases {
-		serial0 = &scifa0;
-	};
-
-	scifa0: serial@e6c40000 {
-		compatible = "renesas,scifa-r8a7790",

-Generic Serial DT Bindings
-
-This document lists a set of generic properties for describing UARTs in a
-device tree.  Whether these properties apply to a particular device depends on
-the DT bindings for the actual device.
-
-Optional properties:
-  - cts-gpios: Must contain a GPIO specifier, referring to the GPIO pin to be
-    used as the UART's CTS line.
-  - dcd-gpios: Must contain a GPIO specifier, referring to the GPIO pin to be
-    used as the UART's DCD line.
-  - dsr-gpios: Must contain a GPIO specifier, referring to the GPIO pin to be
-    used as the UART's DSR line.
-  - dtr-gpios: Must contain a GPIO specifier, referring to the GPIO pin to be
-    used as the UART's DTR line.
-  - rng-gpios: Must contain a GPIO specifier, referring to the GPIO pin to be
-    used as the UART's RNG line.
-  - rts-gpios: Must contain a GPIO specifier, referring to the GPIO pin to be
-    used as the UART's RTS line.
-
-  - uart-has-rtscts: The presence of this property indicates that the
-    UART has dedicated lines for RTS/CTS hardware flow control, and that
-    they are available for use (wired and enabled by pinmux configuration).
-    This depends on both the UART hardware and the board wiring.
-    Note that this property is mutually-exclusive with "cts-gpios" and
-    "rts-gpios" above, unless support is provided to switch between modes
-    dynamically.
-
-
-Examples:
-
-	uart1: serial@48022000 {
-		compatible = "ti,am3352-uart", "ti,omap3-uart";
-		ti,hwmods = "uart2";
-		clock-frequency = <48000000>;
-		reg = <0x48022000 0x2000>;
-		interrupts = <73>;
-		dmas = <&edma 28 0>, <&edma 29 0>;
-		dma-names = "tx", "rx";

-* Rockchip SPI Controller
-
-The Rockchip SPI controller is used to interface with various devices such as flash
-and display controllers using the SPI communication interface.
-
-Required Properties:
-
-- compatible: should be one of the following.
-    "rockchip,rv1108-spi" for rv1108 SoCs.
-    "rockchip,px30-spi", "rockchip,rk3066-spi" for px30 SoCs.
-    "rockchip,rk3036-spi" for rk3036 SoCS.
-    "rockchip,rk3066-spi" for rk3066 SoCs.
-    "rockchip,rk3188-spi" for rk3188 SoCs.
-    "rockchip,rk3228-spi" for rk3228 SoCS.
-    "rockchip,rk3288-spi" for rk3288 SoCs.
-    "rockchip,rk3368-spi" for rk3368 SoCs.
-    "rockchip,rk3399-spi" for rk3399 SoCs.
-- reg: physical base address of the controller and length of memory mapped
-       region.
-- interrupts: The interrupt number to the cpu. The interrupt specifier format
-              depends on the interrupt controller.
-- clocks: Must contain an entry for each entry in clock-names.
-- clock-names: Shall be "spiclk" for the transfer-clock, and "apb_pclk" for
-			   the peripheral clock.
-- #address-cells: should be 1.
-- #size-cells: should be 0.
-
-Optional Properties:
-
-- dmas: DMA specifiers for tx and rx dma. See the DMA client binding,
-		Documentation/devicetree/bindings/dma/dma.txt
-- dma-names: DMA request names should include "tx" and "rx" if present.
-- rx-sample-delay-ns: nanoseconds to delay after the SCLK edge before sampling
-		Rx data (may need to be fine tuned for high capacitance lines).
-		No delay (0) by default.
-- pinctrl-names: Names for the pin configuration(s); may be "default" or
-		"sleep", where the "sleep" configuration may describe the state
-		the pins should be in during system suspend. See also
-		pinctrl/pinctrl-bindings.txt.
-
-
-Example:
-
-	spi0: spi@ff110000 {
-		compatible = "rockchip,rk3066-spi";
-		reg = <0xff110000 0x1000>;

+description:
+  The TI K3 SoC watchdog timer is implemented via the RTI (Real Time
+  Interrupt) IP module. This timer adds a support for windowed watchdog
+  mode, which will signal an error if it is pinged outside the watchdog
+  time window, meaning either too early or too late. The error signal
+  generated can be routed to either interrupt a safety controller or
+  to directly reset the SoC.

+EFI embedded firmware fallback mechanism
+========================================
+
+On some devices the system's EFI code / ROM may contain an embedded copy
+of firmware for some of the system's integrated peripheral devices and
+the peripheral's Linux device-driver needs to access this firmware.
+
+Device drivers which need such firmware can use the
+firmware_request_platform() function for this, note that this is a
+separate fallback mechanism from the other fallback mechanisms and
+this does not use the sysfs interface.
+
+A device driver which needs this can describe the firmware it needs
+using an efi_embedded_fw_desc struct:
+
+.. kernel-doc:: include/linux/efi_embedded_fw.h
+   :functions: efi_embedded_fw_desc
+
+The EFI embedded-fw code works by scanning all EFI_BOOT_SERVICES_CODE memory
+segments for an eight byte sequence matching prefix; if the prefix is found it
+then does a sha256 over length bytes and if that matches makes a copy of length
+bytes and adds that to its list with found firmwares.
+
+To avoid doing this somewhat expensive scan on all systems, dmi matching is
+used. Drivers are expected to export a dmi_system_id array, with each entries'
+driver_data pointing to an efi_embedded_fw_desc.
+
+To register this array with the efi-embedded-fw code, a driver needs to:
+
+1. Always be builtin to the kernel or store the dmi_system_id array in a
+   separate object file which always gets builtin.
+
+2. Add an extern declaration for the dmi_system_id array to
+   include/linux/efi_embedded_fw.h.
+
+3. Add the dmi_system_id array to the embedded_fw_table in
+   drivers/firmware/efi/embedded-firmware.c wrapped in a #ifdef testing that
+   the driver is being builtin.
+
+4. Add "select EFI_EMBEDDED_FIRMWARE if EFI_STUB" to its Kconfig entry.
+
+The firmware_request_platform() function will always first try to load firmware
+with the specified name directly from the disk, so the EFI embedded-fw can
+always be overridden by placing a file under /lib/firmware.
+
+Note that:
+
+1. The code scanning for EFI embedded-firmware runs near the end
+   of start_kernel(), just before calling rest_init(). For normal drivers and
+   subsystems using subsys_initcall() to register themselves this does not
+   matter. This means that code running earlier cannot use EFI
+   embedded-firmware.
+
+2. At the moment the EFI embedded-fw code assumes that firmwares always start at
+   an offset which is a multiple of 8 bytes, if this is not true for your case
+   send in a patch to fix this.
+
+3. At the moment the EFI embedded-fw code only works on x86 because other archs
+   free EFI_BOOT_SERVICES_CODE before the EFI embedded-fw code gets a chance to
+   scan it.
+
+4. The current brute-force scanning of EFI_BOOT_SERVICES_CODE is an ad-hoc
+   brute-force solution. There has been discussion to use the UEFI Platform
+   Initialization (PI) spec's Firmware Volume protocol. This has been rejected
+   because the FV Protocol relies on *internal* interfaces of the PI spec, and:
+   1. The PI spec does not define peripheral firmware at all
+   2. The internal interfaces of the PI spec do not guarantee any backward
+   compatibility. Any implementation details in FV may be subject to change,
+   and may vary system to system. Supporting the FV Protocol would be
+   difficult as it is purposely ambiguous.
+
+Example how to check for and extract embedded firmware
+------------------------------------------------------
+
+To check for, for example Silead touchscreen controller embedded firmware,
+do the following:
+
+1. Boot the system with efi=debug on the kernel commandline
+
+2. cp /sys/kernel/debug/efi/boot_services_code? to your home dir
+
+3. Open the boot_services_code? files in a hex-editor, search for the
+   magic prefix for Silead firmware: F0 00 00 00 02 00 00 00, this gives you
+   the beginning address of the firmware inside the boot_services_code? file.
+
+4. The firmware has a specific pattern, it starts with a 8 byte page-address,
+   typically F0 00 00 00 02 00 00 00 for the first page followed by 32-bit
+   word-address + 32-bit value pairs. With the word-address incrementing 4
+   bytes (1 word) for each pair until a page is complete. A complete page is
+   followed by a new page-address, followed by more word + value pairs. This
+   leads to a very distinct pattern. Scroll down until this pattern stops,
+   this gives you the end of the firmware inside the boot_services_code? file.
+
+5. "dd if=boot_services_code? of=firmware bs=1 skip=<begin-addr> count=<len>"
+   will extract the firmware for you. Inspect the firmware file in a
+   hexeditor to make sure you got the dd parameters correct.
+
+6. Copy it to /lib/firmware under the expected name to test it.
+
+7. If the extracted firmware works, you can use the found info to fill an
+   efi_embedded_fw_desc struct to describe it, run "sha256sum firmware"
+   to get the sha256sum to put in the sha256 field.

 at most. For each logical cluster, there is a corresponding on-disk index to
 describe its cluster type, physical cluster address, etc.

    unmounted.  Watching a file should not require that it be open.

+NFSv4.1 Server Implementation
+=============================
+
+Server support for minorversion 1 can be controlled using the
+/proc/fs/nfsd/versions control file.  The string output returned
+by reading this file will contain either "+4.1" or "-4.1"
+correspondingly.
+
+Currently, server support for minorversion 1 is enabled by default.
+It can be disabled at run time by writing the string "-4.1" to
+the /proc/fs/nfsd/versions control file.  Note that to write this
+control file, the nfsd service must be taken down.  You can use rpc.nfsd
+for this; see rpc.nfsd(8).
+
+(Warning: older servers will interpret "+4.1" and "-4.1" as "+4" and
+"-4", respectively.  Therefore, code meant to work on both new and old
+kernels must turn 4.1 on or off *before* turning support for version 4
+on or off; rpc.nfsd does this correctly.)
+
+The NFSv4 minorversion 1 (NFSv4.1) implementation in nfsd is based
+on RFC 5661.
+
+From the many new features in NFSv4.1 the current implementation
+focuses on the mandatory-to-implement NFSv4.1 Sessions, providing
+"exactly once" semantics and better control and throttling of the
+resources allocated for each client.
+
+The table below, taken from the NFSv4.1 document, lists
+the operations that are mandatory to implement (REQ), optional
+(OPT), and NFSv4.0 operations that are required not to implement (MNI)
+in minor version 1.  The first column indicates the operations that
+are not supported yet by the linux server implementation.
+
+The OPTIONAL features identified and their abbreviations are as follows:
+
+- **pNFS**	Parallel NFS
+- **FDELG**	File Delegations
+- **DDELG**	Directory Delegations
+
+The following abbreviations indicate the linux server implementation status.
+
+- **I**	Implemented NFSv4.1 operations.
+- **NS**	Not Supported.
+- **NS\***	Unimplemented optional feature.

+Implementation notes:
+=====================
+
+SSV:
+  The spec claims this is mandatory, but we don't actually know of any
+  implementations, so we're ignoring it for now.  The server returns
+  NFS4ERR_ENCR_ALG_UNSUPP on EXCHANGE_ID, which should be future-proof.
+
+GSS on the backchannel:
+  Again, theoretically required but not widely implemented (in
+  particular, the current Linux client doesn't request it).  We return
+  NFS4ERR_ENCR_ALG_UNSUPP on CREATE_SESSION.
+
+DELEGPURGE:
+  mandatory only for servers that support CLAIM_DELEGATE_PREV and/or
+  CLAIM_DELEG_PREV_FH (which allows clients to keep delegations that
+  persist across client reboots).  Thus we need not implement this for
+  now.
+
+EXCHANGE_ID:
+  implementation ids are ignored
+
+CREATE_SESSION:
+  backchannel attributes are ignored
+
+SEQUENCE:
+  no support for dynamic slot table renegotiation (optional)
+
+Nonstandard compound limitations:
+  No support for a sessions fore channel RPC compound that requires both a
+  ca_maxrequestsize request and a ca_maxresponsesize reply, so we may
+  fail to live up to the promise we made in CREATE_SESSION fore channel
+  negotiation.

-NFSv4.1 Server Implementation
-
-Server support for minorversion 1 can be controlled using the
-/proc/fs/nfsd/versions control file.  The string output returned
-by reading this file will contain either "+4.1" or "-4.1"
-correspondingly.
-
-Currently, server support for minorversion 1 is enabled by default.
-It can be disabled at run time by writing the string "-4.1" to
-the /proc/fs/nfsd/versions control file.  Note that to write this
-control file, the nfsd service must be taken down.  You can use rpc.nfsd
-for this; see rpc.nfsd(8).
-
-(Warning: older servers will interpret "+4.1" and "-4.1" as "+4" and
-"-4", respectively.  Therefore, code meant to work on both new and old
-kernels must turn 4.1 on or off *before* turning support for version 4
-on or off; rpc.nfsd does this correctly.)
-
-The NFSv4 minorversion 1 (NFSv4.1) implementation in nfsd is based
-on RFC 5661.
-
-From the many new features in NFSv4.1 the current implementation
-focuses on the mandatory-to-implement NFSv4.1 Sessions, providing
-"exactly once" semantics and better control and throttling of the
-resources allocated for each client.
-
-The table below, taken from the NFSv4.1 document, lists
-the operations that are mandatory to implement (REQ), optional
-(OPT), and NFSv4.0 operations that are required not to implement (MNI)
-in minor version 1.  The first column indicates the operations that
-are not supported yet by the linux server implementation.
-
-The OPTIONAL features identified and their abbreviations are as follows:
-	pNFS	Parallel NFS
-	FDELG	File Delegations
-	DDELG	Directory Delegations
-
-The following abbreviations indicate the linux server implementation status.
-	I	Implemented NFSv4.1 operations.
-	NS	Not Supported.
-	NS*	Unimplemented optional feature.

-Implementation notes:
-
-SSV:
-* The spec claims this is mandatory, but we don't actually know of any
-  implementations, so we're ignoring it for now.  The server returns
-  NFS4ERR_ENCR_ALG_UNSUPP on EXCHANGE_ID, which should be future-proof.
-
-GSS on the backchannel:
-* Again, theoretically required but not widely implemented (in
-  particular, the current Linux client doesn't request it).  We return
-  NFS4ERR_ENCR_ALG_UNSUPP on CREATE_SESSION.
-
-DELEGPURGE:
-* mandatory only for servers that support CLAIM_DELEGATE_PREV and/or
-  CLAIM_DELEG_PREV_FH (which allows clients to keep delegations that
-  persist across client reboots).  Thus we need not implement this for
-  now.
-
-EXCHANGE_ID:
-* implementation ids are ignored
-
-CREATE_SESSION:
-* backchannel attributes are ignored
-
-SEQUENCE:
-* no support for dynamic slot table renegotiation (optional)
-
-Nonstandard compound limitations:
-* No support for a sessions fore channel RPC compound that requires both a
-  ca_maxrequestsize request and a ca_maxresponsesize reply, so we may
-  fail to live up to the promise we made in CREATE_SESSION fore channel
-  negotiation.

+Optimized MPEG Filesystem (OMFS)
+================================
+
+Overview
+========
+
+OMFS is a filesystem created by SonicBlue for use in the ReplayTV DVR
+and Rio Karma MP3 player.  The filesystem is extent-based, utilizing
+block sizes from 2k to 8k, with hash-based directories.  This
+filesystem driver may be used to read and write disks from these
+devices.
+
+Note, it is not recommended that this FS be used in place of a general
+filesystem for your own streaming media device.  Native Linux filesystems
+will likely perform better.

+
+Various utilities, including mkomfs and omfsck, are included with
+omfsprogs, available at:

+
+Options
+=======
+
+OMFS supports the following mount-time options:
+
+    ============   ========================================
+    uid=n          make all files owned by specified user
+    gid=n          make all files owned by specified group

+    dmask=xxx      set umask to xxx for directories
+    ============   ========================================
+
+Disk format
+===========
+
+OMFS discriminates between "sysblocks" and normal data blocks.  The sysblock
+group consists of super block information, file metadata, directory structures,
+and extents.  Each sysblock has a header containing CRCs of the entire
+sysblock, and may be mirrored in successive blocks on the disk.  A sysblock may
+have a smaller size than a data block, but since they are both addressed by the
+same 64-bit block number, any remaining space in the smaller sysblock is
+unused.
+
+Sysblock header information::
+
+    struct omfs_header {
+	    __be64 h_self;                  /* FS block where this is located */
+	    __be32 h_body_size;             /* size of useful data after header */
+	    __be16 h_crc;                   /* crc-ccitt of body_size bytes */
+	    char h_fill1[2];
+	    u8 h_version;                   /* version, always 1 */
+	    char h_type;                    /* OMFS_INODE_X */
+	    u8 h_magic;                     /* OMFS_IMAGIC */
+	    u8 h_check_xor;                 /* XOR of header bytes before this */
+	    __be32 h_fill2;
+    };
+
+Files and directories are both represented by omfs_inode::
+
+    struct omfs_inode {
+	    struct omfs_header i_head;      /* header */
+	    __be64 i_parent;                /* parent containing this inode */
+	    __be64 i_sibling;               /* next inode in hash bucket */
+	    __be64 i_ctime;                 /* ctime, in milliseconds */
+	    char i_fill1[35];
+	    char i_type;                    /* OMFS_[DIR,FILE] */
+	    __be32 i_fill2;
+	    char i_fill3[64];
+	    char i_name[OMFS_NAMELEN];      /* filename */
+	    __be64 i_size;                  /* size of file, in bytes */
+    };
+
+Directories in OMFS are implemented as a large hash table.  Filenames are
+hashed then prepended into the bucket list beginning at OMFS_DIR_START.
+Lookup requires hashing the filename, then seeking across i_sibling pointers
+until a match is found on i_name.  Empty buckets are represented by block
+pointers with all-1s (~0).
+
+A file is an omfs_inode structure followed by an extent table beginning at
+OMFS_EXTENT_START::
+
+    struct omfs_extent_entry {
+	    __be64 e_cluster;               /* start location of a set of blocks */
+	    __be64 e_blocks;                /* number of blocks after e_cluster */
+    };
+
+    struct omfs_extent {
+	    __be64 e_next;                  /* next extent table location */
+	    __be32 e_extent_count;          /* total # extents in this table */
+	    __be32 e_fill;
+	    struct omfs_extent_entry e_entry;       /* start of extent entries */
+    };
+
+Each extent holds the block offset followed by number of blocks allocated to
+the extent.  The final extent in each table is a terminator with e_cluster
+being ~0 and e_blocks being ones'-complement of the total number of blocks
+in the table.
+
+If this table overflows, a continuation inode is written and pointed to by
+e_next.  These have a header but lack the rest of the inode structure.

+Permission model
+----------------
+
+Permission checking in the overlay filesystem follows these principles:
+
+ 1) permission check SHOULD return the same result before and after copy up
+
+ 2) task creating the overlay mount MUST NOT gain additional privileges
+
+ 3) non-mounting task MAY gain additional privileges through the overlay,
+ compared to direct access on underlying lower or upper filesystems
+
+This is achieved by performing two permission checks on each access
+
+ a) check if current task is allowed access based on local DAC (owner,
+    group, mode and posix acl), as well as MAC checks
+
+ b) check if mounting task would be allowed real operation on lower or
+    upper layer based on underlying filesystem permissions, again including
+    MAC checks
+
+Check (a) ensures consistency (1) since owner, group, mode and posix acls
+are copied up.  On the other hand it can result in server enforced
+permissions (used by NFS, for example) being ignored (3).
+
+Check (b) ensures that no task gains permissions to underlying layers that
+the mounting task does not have (2).  This also means that it is possible
+to create setups where the consistency rule (1) does not hold; normally,
+however, the mounting task will have sufficient privileges to perform all
+operations.
+
+Another way to demonstrate this model is drawing parallels between
+
+  mount -t overlay overlay -olowerdir=/lower,upperdir=/upper,... /merged
+
+and
+
+  cp -a /lower /upper
+  mount --bind /upper /merged
+
+The resulting access permissions should be the same.  The difference is in

-              The CommitLimit is calculated with the following formula:
-              CommitLimit = ([total RAM pages] - [total huge TLB pages]) *
-                             overcommit_ratio / 100 + [total swap pages]

+
               For example, on a system with 1G of physical RAM and 7G
               of swap with a `vm.overcommit_ratio` of 30 it would

 Summary

 The /proc file system serves information about the running system. It not only
 allows access to process data but also allows you to request the kernel status
 by reading files in the hierarchy.
 
 The directory  structure  of /proc reflects the types of information and makes
 it easy, if not obvious, where to look for specific data.

 Certain aspects  of  kernel  behavior  can be modified at runtime, without the
 need to  recompile  the kernel, or even to reboot the system. The files in the
 /proc/sys tree  can  not only be read, but also modified. You can use the echo
 command to write value into these files, thereby changing the default settings
 of the kernel.

+Improve plane atomic_check helpers
+----------------------------------
+
+Aside from the clipped coordinates right above there's a few suboptimal things
+with the current helpers:
+
+- drm_plane_helper_funcs->atomic_check gets called for enabled or disabled
+  planes. At best this seems to confuse drivers, worst it means they blow up
+  when the plane is disabled without the CRTC. The only special handling is
+  resetting values in the plane state structures, which instead should be moved
+  into the drm_plane_funcs->atomic_duplicate_state functions.
+
+- Once that's done, helpers could stop calling ->atomic_check for disabled
+  planes.
+
+- Then we could go through all the drivers and remove the more-or-less confused
+  checks for plane_state->fb and plane_state->crtc.

+generation devices are grouped into 4 distinct configurations: '1rail' for
+single-rail devices, '2rail' for dual-rail devices, '3rail' for 3-rail devices,
+and 'hv' for high voltage single-rail devices. Consult the individual datasheets

+
+
+Description
+-----------
+
+Chips in this series are multi-phase step-down converters with one or two
+output channels and up to 8 phases per channel.
+
+
+Usage Notes
+-----------
+
+This driver does not probe for PMBus devices. You will have to instantiate
+devices explicitly.
+
+Example: the following commands will load the driver for an TPS53681 at address
+0x60 on I2C bus #1::
+
+	# modprobe tps53679
+	# echo tps53681 0x60 > /sys/bus/i2c/devices/i2c-1/new_device

+==============================
+Building Linux with Clang/LLVM
+==============================
+
+This document covers how to build the Linux kernel with Clang and LLVM
+utilities.
+
+About
+-----
+
+The Linux kernel has always traditionally been compiled with GNU toolchains
+such as GCC and binutils. Ongoing work has allowed for `Clang
+<https://clang.llvm.org/>`_ and `LLVM <https://llvm.org/>`_ utilities to be
+used as viable substitutes. Distributions such as `Android
+<https://www.android.com/>`_, `ChromeOS
+<https://www.chromium.org/chromium-os>`_, and `OpenMandriva
+<https://www.openmandriva.org/>`_ use Clang built kernels.  `LLVM is a
+collection of toolchain components implemented in terms of C++ objects
+<https://www.aosabook.org/en/llvm.html>`_. Clang is a front-end to LLVM that
+supports C and the GNU C extensions required by the kernel, and is pronounced
+"klang," not "see-lang."
+
+Clang
+-----
+
+The compiler used can be swapped out via `CC=` command line argument to `make`.
+`CC=` should be set when selecting a config and during a build.
+
+	make CC=clang defconfig
+
+	make CC=clang
+
+Cross Compiling
+---------------
+
+A single Clang compiler binary will typically contain all supported backends,
+which can help simplify cross compiling.
+
+	ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- make CC=clang
+
+`CROSS_COMPILE` is not used to prefix the Clang compiler binary, instead
+`CROSS_COMPILE` is used to set a command line flag: `--target <triple>`. For
+example:
+
+	clang --target aarch64-linux-gnu foo.c
+
+LLVM Utilities
+--------------
+
+LLVM has substitutes for GNU binutils utilities. Kbuild supports `LLVM=1`
+to enable them.
+
+	make LLVM=1
+
+They can be enabled individually. The full list of the parameters:
+
+	make CC=clang LD=ld.lld AR=llvm-ar NM=llvm-nm STRIP=llvm-strip \\
+	  OBJCOPY=llvm-objcopy OBJDUMP=llvm-objdump OBJSIZE=llvm-size \\
+	  READELF=llvm-readelf HOSTCC=clang HOSTCXX=clang++ HOSTAR=llvm-ar \\
+	  HOSTLD=ld.lld
+
+Currently, the integrated assembler is disabled by default. You can pass
+`LLVM_IAS=1` to enable it.

+==========================
+Lock types and their rules
+==========================
+
+Introduction
+============
+
+The kernel provides a variety of locking primitives which can be divided
+into two categories:
+
+ - Sleeping locks
+ - Spinning locks
+
+This document conceptually describes these lock types and provides rules
+for their nesting, including the rules for use under PREEMPT_RT.
+
+
+Lock categories
+===============
+
+Sleeping locks
+--------------
+
+Sleeping locks can only be acquired in preemptible task context.
+
+Although implementations allow try_lock() from other contexts, it is
+necessary to carefully evaluate the safety of unlock() as well as of
+try_lock().  Furthermore, it is also necessary to evaluate the debugging
+versions of these primitives.  In short, don't acquire sleeping locks from
+other contexts unless there is no other option.
+
+Sleeping lock types:
+
+ - mutex
+ - rt_mutex
+ - semaphore
+ - rw_semaphore
+ - ww_mutex
+ - percpu_rw_semaphore
+
+On PREEMPT_RT kernels, these lock types are converted to sleeping locks:
+
+ - spinlock_t
+ - rwlock_t
+
+Spinning locks
+--------------
+
+ - raw_spinlock_t
+ - bit spinlocks
+
+On non-PREEMPT_RT kernels, these lock types are also spinning locks:
+
+ - spinlock_t
+ - rwlock_t
+
+Spinning locks implicitly disable preemption and the lock / unlock functions
+can have suffixes which apply further protections:
+
+ ===================  ====================================================
+ _bh()                Disable / enable bottom halves (soft interrupts)
+ _irq()               Disable / enable interrupts
+ _irqsave/restore()   Save and disable / restore interrupt disabled state
+ ===================  ====================================================
+
+Owner semantics
+===============
+
+The aforementioned lock types except semaphores have strict owner
+semantics:
+
+  The context (task) that acquired the lock must release it.
+
+rw_semaphores have a special interface which allows non-owner release for
+readers.
+
+
+rtmutex
+=======
+
+RT-mutexes are mutexes with support for priority inheritance (PI).
+
+PI has limitations on non-PREEMPT_RT kernels due to preemption and
+interrupt disabled sections.
+
+PI clearly cannot preempt preemption-disabled or interrupt-disabled
+regions of code, even on PREEMPT_RT kernels.  Instead, PREEMPT_RT kernels
+execute most such regions of code in preemptible task context, especially
+interrupt handlers and soft interrupts.  This conversion allows spinlock_t
+and rwlock_t to be implemented via RT-mutexes.
+
+
+semaphore
+=========
+
+semaphore is a counting semaphore implementation.
+
+Semaphores are often used for both serialization and waiting, but new use
+cases should instead use separate serialization and wait mechanisms, such
+as mutexes and completions.
+
+semaphores and PREEMPT_RT
+----------------------------
+
+PREEMPT_RT does not change the semaphore implementation because counting
+semaphores have no concept of owners, thus preventing PREEMPT_RT from
+providing priority inheritance for semaphores.  After all, an unknown
+owner cannot be boosted. As a consequence, blocking on semaphores can
+result in priority inversion.
+
+
+rw_semaphore
+============
+
+rw_semaphore is a multiple readers and single writer lock mechanism.
+
+On non-PREEMPT_RT kernels the implementation is fair, thus preventing
+writer starvation.
+
+rw_semaphore complies by default with the strict owner semantics, but there
+exist special-purpose interfaces that allow non-owner release for readers.
+These interfaces work independent of the kernel configuration.
+
+rw_semaphore and PREEMPT_RT
+---------------------------
+
+PREEMPT_RT kernels map rw_semaphore to a separate rt_mutex-based
+implementation, thus changing the fairness:
+
+ Because an rw_semaphore writer cannot grant its priority to multiple
+ readers, a preempted low-priority reader will continue holding its lock,
+ thus starving even high-priority writers.  In contrast, because readers
+ can grant their priority to a writer, a preempted low-priority writer will
+ have its priority boosted until it releases the lock, thus preventing that
+ writer from starving readers.
+
+
+raw_spinlock_t and spinlock_t
+=============================
+
+raw_spinlock_t
+--------------
+
+raw_spinlock_t is a strict spinning lock implementation regardless of the
+kernel configuration including PREEMPT_RT enabled kernels.
+
+raw_spinlock_t is a strict spinning lock implementation in all kernels,
+including PREEMPT_RT kernels.  Use raw_spinlock_t only in real critical
+core code, low-level interrupt handling and places where disabling
+preemption or interrupts is required, for example, to safely access
+hardware state.  raw_spinlock_t can sometimes also be used when the
+critical section is tiny, thus avoiding RT-mutex overhead.
+
+spinlock_t
+----------
+
+The semantics of spinlock_t change with the state of PREEMPT_RT.
+
+On a non-PREEMPT_RT kernel spinlock_t is mapped to raw_spinlock_t and has
+exactly the same semantics.
+
+spinlock_t and PREEMPT_RT
+-------------------------
+
+On a PREEMPT_RT kernel spinlock_t is mapped to a separate implementation
+based on rt_mutex which changes the semantics:
+
+ - Preemption is not disabled.
+
+ - The hard interrupt related suffixes for spin_lock / spin_unlock
+   operations (_irq, _irqsave / _irqrestore) do not affect the CPU's
+   interrupt disabled state.
+
+ - The soft interrupt related suffix (_bh()) still disables softirq
+   handlers.
+
+   Non-PREEMPT_RT kernels disable preemption to get this effect.
+
+   PREEMPT_RT kernels use a per-CPU lock for serialization which keeps
+   preemption disabled. The lock disables softirq handlers and also
+   prevents reentrancy due to task preemption.
+
+PREEMPT_RT kernels preserve all other spinlock_t semantics:
+
+ - Tasks holding a spinlock_t do not migrate.  Non-PREEMPT_RT kernels
+   avoid migration by disabling preemption.  PREEMPT_RT kernels instead
+   disable migration, which ensures that pointers to per-CPU variables
+   remain valid even if the task is preempted.
+
+ - Task state is preserved across spinlock acquisition, ensuring that the
+   task-state rules apply to all kernel configurations.  Non-PREEMPT_RT
+   kernels leave task state untouched.  However, PREEMPT_RT must change
+   task state if the task blocks during acquisition.  Therefore, it saves
+   the current task state before blocking and the corresponding lock wakeup
+   restores it, as shown below::
+
+    task->state = TASK_INTERRUPTIBLE
+     lock()
+       block()
+         task->saved_state = task->state
+	 task->state = TASK_UNINTERRUPTIBLE
+	 schedule()
+					lock wakeup
+					  task->state = task->saved_state
+
+   Other types of wakeups would normally unconditionally set the task state
+   to RUNNING, but that does not work here because the task must remain
+   blocked until the lock becomes available.  Therefore, when a non-lock
+   wakeup attempts to awaken a task blocked waiting for a spinlock, it
+   instead sets the saved state to RUNNING.  Then, when the lock
+   acquisition completes, the lock wakeup sets the task state to the saved
+   state, in this case setting it to RUNNING::
+
+    task->state = TASK_INTERRUPTIBLE
+     lock()
+       block()
+         task->saved_state = task->state
+	 task->state = TASK_UNINTERRUPTIBLE
+	 schedule()
+					non lock wakeup
+					  task->saved_state = TASK_RUNNING
+
+					lock wakeup
+					  task->state = task->saved_state
+
+   This ensures that the real wakeup cannot be lost.
+
+
+rwlock_t
+========
+
+rwlock_t is a multiple readers and single writer lock mechanism.
+
+Non-PREEMPT_RT kernels implement rwlock_t as a spinning lock and the
+suffix rules of spinlock_t apply accordingly. The implementation is fair,
+thus preventing writer starvation.
+
+rwlock_t and PREEMPT_RT
+-----------------------
+
+PREEMPT_RT kernels map rwlock_t to a separate rt_mutex-based
+implementation, thus changing semantics:
+
+ - All the spinlock_t changes also apply to rwlock_t.
+
+ - Because an rwlock_t writer cannot grant its priority to multiple
+   readers, a preempted low-priority reader will continue holding its lock,
+   thus starving even high-priority writers.  In contrast, because readers
+   can grant their priority to a writer, a preempted low-priority writer
+   will have its priority boosted until it releases the lock, thus
+   preventing that writer from starving readers.
+
+
+PREEMPT_RT caveats
+==================
+
+spinlock_t and rwlock_t
+-----------------------
+
+These changes in spinlock_t and rwlock_t semantics on PREEMPT_RT kernels
+have a few implications.  For example, on a non-PREEMPT_RT kernel the
+following code sequence works as expected::
+
+   local_irq_disable();
+   spin_lock(&lock);
+
+and is fully equivalent to::
+
+   spin_lock_irq(&lock);
+
+Same applies to rwlock_t and the _irqsave() suffix variants.
+
+On PREEMPT_RT kernel this code sequence breaks because RT-mutex requires a
+fully preemptible context.  Instead, use spin_lock_irq() or
+spin_lock_irqsave() and their unlock counterparts.  In cases where the
+interrupt disabling and locking must remain separate, PREEMPT_RT offers a
+local_lock mechanism.  Acquiring the local_lock pins the task to a CPU,
+allowing things like per-CPU interrupt disabled locks to be acquired.
+However, this approach should be used only where absolutely necessary.
+
+
+raw_spinlock_t
+--------------
+
+Acquiring a raw_spinlock_t disables preemption and possibly also
+interrupts, so the critical section must avoid acquiring a regular
+spinlock_t or rwlock_t, for example, the critical section must avoid
+allocating memory.  Thus, on a non-PREEMPT_RT kernel the following code
+works perfectly::
+
+  raw_spin_lock(&lock);
+  p = kmalloc(sizeof(*p), GFP_ATOMIC);
+
+But this code fails on PREEMPT_RT kernels because the memory allocator is
+fully preemptible and therefore cannot be invoked from truly atomic
+contexts.  However, it is perfectly fine to invoke the memory allocator
+while holding normal non-raw spinlocks because they do not disable
+preemption on PREEMPT_RT kernels::
+
+  spin_lock(&lock);
+  p = kmalloc(sizeof(*p), GFP_ATOMIC);
+
+
+bit spinlocks
+-------------
+
+PREEMPT_RT cannot substitute bit spinlocks because a single bit is too
+small to accommodate an RT-mutex.  Therefore, the semantics of bit
+spinlocks are preserved on PREEMPT_RT kernels, so that the raw_spinlock_t
+caveats also apply to bit spinlocks.
+
+Some bit spinlocks are replaced with regular spinlock_t for PREEMPT_RT
+using conditional (#ifdef'ed) code changes at the usage site.  In contrast,
+usage-site changes are not needed for the spinlock_t substitution.
+Instead, conditionals in header files and the core locking implemementation
+enable the compiler to do the substitution transparently.
+
+
+Lock type nesting rules
+=======================
+
+The most basic rules are:
+
+  - Lock types of the same lock category (sleeping, spinning) can nest
+    arbitrarily as long as they respect the general lock ordering rules to
+    prevent deadlocks.
+
+  - Sleeping lock types cannot nest inside spinning lock types.
+
+  - Spinning lock types can nest inside sleeping lock types.
+
+These constraints apply both in PREEMPT_RT and otherwise.
+
+The fact that PREEMPT_RT changes the lock category of spinlock_t and
+rwlock_t from spinning to sleeping means that they cannot be acquired while
+holding a raw spinlock.  This results in the following nesting ordering:
+
+  1) Sleeping locks
+  2) spinlock_t and rwlock_t
+  3) raw_spinlock_t and bit spinlocks
+
+Lockdep will complain if these constraints are violated, both in
+PREEMPT_RT and otherwise.

+14-bit Bayer formats expanded to 16 bits
+
+
+Description
+===========
+
+These four pixel formats are raw sRGB / Bayer formats with 14 bits per
+colour. Each sample is stored in a 16-bit word, with two unused high
+bits filled with zeros. Each n-pixel row contains n/2 green samples
+and n/2 blue or red samples, with alternating red and blue rows. Bytes
+are stored in memory in little endian order. They are conventionally
+described as GRGR... BGBG..., RGRG... GBGB..., etc. Below is an
+example of a small V4L2_PIX_FMT_SBGGR14 image:
+
+**Byte Order.**
+Each cell is one byte, the two most significant bits in the high bytes are
+zero.

+==========================
+MHI (Modem Host Interface)
+==========================
+
+This document provides information about the MHI protocol.
+
+Overview
+========
+
+MHI is a protocol developed by Qualcomm Innovation Center, Inc. It is used
+by the host processors to control and communicate with modem devices over high
+speed peripheral buses or shared memory. Even though MHI can be easily adapted
+to any peripheral buses, it is primarily used with PCIe based devices. MHI
+provides logical channels over the physical buses and allows transporting the
+modem protocols, such as IP data packets, modem control messages, and
+diagnostics over at least one of those logical channels. Also, the MHI
+protocol provides data acknowledgment feature and manages the power state of the
+modems via one or more logical channels.
+
+MHI Internals
+=============
+
+MMIO
+----
+
+MMIO (Memory mapped IO) consists of a set of registers in the device hardware,
+which are mapped to the host memory space by the peripheral buses like PCIe.
+Following are the major components of MMIO register space:
+
+MHI control registers: Access to MHI configurations registers
+
+MHI BHI registers: BHI (Boot Host Interface) registers are used by the host
+for downloading the firmware to the device before MHI initialization.
+
+Channel Doorbell array: Channel Doorbell (DB) registers used by the host to
+notify the device when there is new work to do.
+
+Event Doorbell array: Associated with event context array, the Event Doorbell
+(DB) registers are used by the host to notify the device when new events are
+available.
+
+Debug registers: A set of registers and counters used by the device to expose
+debugging information like performance, functional, and stability to the host.
+
+Data structures
+---------------
+
+All data structures used by MHI are in the host system memory. Using the
+physical interface, the device accesses those data structures. MHI data
+structures and data buffers in the host system memory regions are mapped for
+the device.
+
+Channel context array: All channel configurations are organized in channel
+context data array.
+
+Transfer rings: Used by the host to schedule work items for a channel. The
+transfer rings are organized as a circular queue of Transfer Descriptors (TD).
+
+Event context array: All event configurations are organized in the event context
+data array.
+
+Event rings: Used by the device to send completion and state transition messages
+to the host
+
+Command context array: All command configurations are organized in command
+context data array.
+
+Command rings: Used by the host to send MHI commands to the device. The command
+rings are organized as a circular queue of Command Descriptors (CD).
+
+Channels
+--------
+
+MHI channels are logical, unidirectional data pipes between a host and a device.
+The concept of channels in MHI is similar to endpoints in USB. MHI supports up
+to 256 channels. However, specific device implementations may support less than
+the maximum number of channels allowed.
+
+Two unidirectional channels with their associated transfer rings form a
+bidirectional data pipe, which can be used by the upper-layer protocols to
+transport application data packets (such as IP packets, modem control messages,
+diagnostics messages, and so on). Each channel is associated with a single
+transfer ring.
+
+Transfer rings
+--------------
+
+Transfers between the host and device are organized by channels and defined by
+Transfer Descriptors (TD). TDs are managed through transfer rings, which are
+defined for each channel between the device and host and reside in the host
+memory. TDs consist of one or more ring elements (or transfer blocks)::
+
+        [Read Pointer (RP)] ----------->[Ring Element] } TD
+        [Write Pointer (WP)]-           [Ring Element]
+                             -          [Ring Element]
+                              --------->[Ring Element]
+                                        [Ring Element]
+
+Below is the basic usage of transfer rings:
+
+* Host allocates memory for transfer ring.
+* Host sets the base pointer, read pointer, and write pointer in corresponding
+  channel context.
+* Ring is considered empty when RP == WP.
+* Ring is considered full when WP + 1 == RP.
+* RP indicates the next element to be serviced by the device.
+* When the host has a new buffer to send, it updates the ring element with
+  buffer information, increments the WP to the next element and rings the
+  associated channel DB.
+
+Event rings
+-----------
+
+Events from the device to host are organized in event rings and defined by Event
+Descriptors (ED). Event rings are used by the device to report events such as
+data transfer completion status, command completion status, and state changes
+to the host. Event rings are the array of EDs that resides in the host
+memory. EDs consist of one or more ring elements (or transfer blocks)::
+
+        [Read Pointer (RP)] ----------->[Ring Element] } ED
+        [Write Pointer (WP)]-           [Ring Element]
+                             -          [Ring Element]
+                              --------->[Ring Element]
+                                        [Ring Element]
+
+Below is the basic usage of event rings:
+
+* Host allocates memory for event ring.
+* Host sets the base pointer, read pointer, and write pointer in corresponding
+  channel context.
+* Both host and device has a local copy of RP, WP.
+* Ring is considered empty (no events to service) when WP + 1 == RP.
+* Ring is considered full of events when RP == WP.
+* When there is a new event the device needs to send, the device updates ED
+  pointed by RP, increments the RP to the next element and triggers the
+  interrupt.
+
+Ring Element
+------------
+
+A Ring Element is a data structure used to transfer a single block
+of data between the host and the device. Transfer ring element types contain a
+single buffer pointer, the size of the buffer, and additional control
+information. Other ring element types may only contain control and status
+information. For single buffer operations, a ring descriptor is composed of a
+single element. For large multi-buffer operations (such as scatter and gather),
+elements can be chained to form a longer descriptor.
+
+MHI Operations
+==============
+
+MHI States
+----------
+
+MHI_STATE_RESET
+~~~~~~~~~~~~~~~
+MHI is in reset state after power-up or hardware reset. The host is not allowed
+to access device MMIO register space.
+
+MHI_STATE_READY
+~~~~~~~~~~~~~~~
+MHI is ready for initialization. The host can start MHI initialization by
+programming MMIO registers.
+
+MHI_STATE_M0
+~~~~~~~~~~~~
+MHI is running and operational in the device. The host can start channels by
+issuing channel start command.
+
+MHI_STATE_M1
+~~~~~~~~~~~~
+MHI operation is suspended by the device. This state is entered when the
+device detects inactivity at the physical interface within a preset time.
+
+MHI_STATE_M2
+~~~~~~~~~~~~
+MHI is in low power state. MHI operation is suspended and the device may
+enter lower power mode.
+
+MHI_STATE_M3
+~~~~~~~~~~~~
+MHI operation stopped by the host. This state is entered when the host suspends
+MHI operation.
+
+MHI Initialization
+------------------
+
+After system boots, the device is enumerated over the physical interface.
+In the case of PCIe, the device is enumerated and assigned BAR-0 for
+the device's MMIO register space. To initialize the MHI in a device,
+the host performs the following operations:
+
+* Allocates the MHI context for event, channel and command arrays.
+* Initializes the context array, and prepares interrupts.
+* Waits until the device enters READY state.
+* Programs MHI MMIO registers and sets device into MHI_M0 state.
+* Waits for the device to enter M0 state.
+
+MHI Data Transfer
+-----------------
+
+MHI data transfer is initiated by the host to transfer data to the device.
+Following are the sequence of operations performed by the host to transfer
+data to device:
+
+* Host prepares TD with buffer information.
+* Host increments the WP of the corresponding channel transfer ring.
+* Host rings the channel DB register.
+* Device wakes up to process the TD.
+* Device generates a completion event for the processed TD by updating ED.
+* Device increments the RP of the corresponding event ring.
+* Device triggers IRQ to wake up the host.
+* Host wakes up and checks the event ring for completion event.
+* Host updates the WP of the corresponding event ring to indicate that the
+  data transfer has been completed successfully.

+MHI Topology
+============
+
+This document provides information about the MHI topology modeling and
+representation in the kernel.
+
+MHI Controller
+--------------
+
+MHI controller driver manages the interaction with the MHI client devices
+such as the external modems and WiFi chipsets. It is also the MHI bus master
+which is in charge of managing the physical link between the host and device.
+It is however not involved in the actual data transfer as the data transfer
+is taken care by the physical bus such as PCIe. Each controller driver exposes
+channels and events based on the client device type.
+
+Below are the roles of the MHI controller driver:
+
+* Turns on the physical bus and establishes the link to the device
+* Configures IRQs, IOMMU, and IOMEM
+* Allocates struct mhi_controller and registers with the MHI bus framework
+  with channel and event configurations using mhi_register_controller.
+* Initiates power on and shutdown sequence
+* Initiates suspend and resume power management operations of the device.
+
+MHI Device
+----------
+
+MHI device is the logical device which binds to a maximum of two MHI channels
+for bi-directional communication. Once MHI is in powered on state, the MHI
+core will create MHI devices based on the channel configuration exposed
+by the controller. There can be a single MHI device for each channel or for a
+couple of channels.
+
+Each supported device is enumerated in::
+
+        /sys/bus/mhi/devices/
+
+MHI Driver
+----------
+
+MHI driver is the client driver which binds to one or more MHI devices. The MHI
+driver sends and receives the upper-layer protocol packets like IP packets,
+modem control messages, and diagnostics messages over MHI. The MHI core will
+bind the MHI devices to the MHI driver.
+
+Each supported driver is enumerated in::
+
+        /sys/bus/mhi/drivers/
+
+Below are the roles of the MHI driver:
+
+* Registers the driver with the MHI bus framework using mhi_driver_register.
+* Prepares the device for transfer by calling mhi_prepare_for_transfer.
+* Initiates data transfer by calling mhi_queue_transfer.
+* Once the data transfer is finished, calls mhi_unprepare_from_transfer to
+  end data transfer.

+Introduction of Uacce
+---------------------
+
+Uacce (Unified/User-space-access-intended Accelerator Framework) targets to
+provide Shared Virtual Addressing (SVA) between accelerators and processes.
+So accelerator can access any data structure of the main cpu.
+This differs from the data sharing between cpu and io device, which share
+only data content rather than address.
+Because of the unified address, hardware and user space of process can
+share the same virtual address in the communication.
+Uacce takes the hardware accelerator as a heterogeneous processor, while
+IOMMU share the same CPU page tables and as a result the same translation
+from va to pa.

+Architecture
+------------
+
+Uacce is the kernel module, taking charge of iommu and address sharing.
+The user drivers and libraries are called WarpDrive.
+
+The uacce device, built around the IOMMU SVA API, can access multiple
+address spaces, including the one without PASID.
+
+A virtual concept, queue, is used for the communication. It provides a
+FIFO-like interface. And it maintains a unified address space between the
+application and all involved hardware.

+
+How does it work
+----------------
+
+Uacce uses mmap and IOMMU to play the trick.
+
+Uacce creates a chrdev for every device registered to it. New queue is
+created when user application open the chrdev. The file descriptor is used
+as the user handle of the queue.
+The accelerator device present itself as an Uacce object, which exports as
+a chrdev to the user space. The user application communicates with the
+hardware by ioctl (as control path) or share memory (as data path).
+
+The control path to the hardware is via file operation, while data path is
+via mmap space of the queue fd.
+
+The queue file address space:
+
+::
+
+   /**
+   * enum uacce_qfrt: qfrt type
+   * @UACCE_QFRT_MMIO: device mmio region
+   * @UACCE_QFRT_DUS: device user share region
+   */
+  enum uacce_qfrt {
+          UACCE_QFRT_MMIO = 0,
+          UACCE_QFRT_DUS = 1,
+  };
+
+All regions are optional and differ from device type to type.
+Each region can be mmapped only once, otherwise -EEXIST returns.
+
+The device mmio region is mapped to the hardware mmio space. It is generally
+used for doorbell or other notification to the hardware. It is not fast enough
+as data channel.
+
+The device user share region is used for share data buffer between user process
+and device.
+
+
+The Uacce register API
+----------------------
+
+The register API is defined in uacce.h.
+
+::
+
+  struct uacce_interface {
+    char name[UACCE_MAX_NAME_SIZE];
+    unsigned int flags;
+    const struct uacce_ops *ops;
+  };
+
+According to the IOMMU capability, uacce_interface flags can be:
+
+::
+
+  /**
+   * UACCE Device flags:
+   * UACCE_DEV_SVA: Shared Virtual Addresses
+   *              Support PASID
+   *              Support device page faults (PCI PRI or SMMU Stall)
+   */
+  #define UACCE_DEV_SVA               BIT(0)
+
+  struct uacce_device *uacce_alloc(struct device *parent,
+                                   struct uacce_interface *interface);
+  int uacce_register(struct uacce_device *uacce);
+  void uacce_remove(struct uacce_device *uacce);
+
+uacce_register results can be:
+
+a. If uacce module is not compiled, ERR_PTR(-ENODEV)
+
+b. Succeed with the desired flags
+
+c. Succeed with the negotiated flags, for example
+
+  uacce_interface.flags = UACCE_DEV_SVA but uacce->flags = ~UACCE_DEV_SVA
+
+  So user driver need check return value as well as the negotiated uacce->flags.
+
+
+The user driver
+---------------
+
+The queue file mmap space will need a user driver to wrap the communication
+protocol. Uacce provides some attributes in sysfs for the user driver to
+match the right accelerator accordingly.
+More details in Documentation/ABI/testing/sysfs-driver-uacce.

+Bare UDP Tunnelling Module Documentation
+========================================
+
+There are various L3 encapsulation standards using UDP being discussed to
+leverage the UDP based load balancing capability of different networks.
+MPLSoUDP (__ https://tools.ietf.org/html/rfc7510) is one among them.
+
+The Bareudp tunnel module provides a generic L3 encapsulation tunnelling
+support for tunnelling different L3 protocols like MPLS, IP, NSH etc. inside
+a UDP tunnel.
+
+Special Handling
+----------------
+The bareudp device supports special handling for MPLS & IP as they can have
+multiple ethertypes.
+MPLS procotcol can have ethertypes ETH_P_MPLS_UC  (unicast) & ETH_P_MPLS_MC (multicast).
+IP protocol can have ethertypes ETH_P_IP (v4) & ETH_P_IPV6 (v6).
+This special handling can be enabled only for ethertypes ETH_P_IP & ETH_P_MPLS_UC
+with a flag called multiproto mode.
+
+Usage
+------
+
+1) Device creation & deletion
+
+    a) ip link add dev bareudp0 type bareudp dstport 6635 ethertype 0x8847.
+
+       This creates a bareudp tunnel device which tunnels L3 traffic with ethertype
+       0x8847 (MPLS traffic). The destination port of the UDP header will be set to
+       6635.The device will listen on UDP port 6635 to receive traffic.
+
+    b) ip link delete bareudp0
+
+2) Device creation with multiple proto mode enabled
+
+There are two ways to create a bareudp device for MPLS & IP with multiproto mode
+enabled.
+
+    a) ip link add dev  bareudp0 type bareudp dstport 6635 ethertype 0x8847 multiproto
+
+    b) ip link add dev  bareudp0 type bareudp dstport 6635 ethertype mpls
+
+3) Device Usage
+
+The bareudp device could be used along with OVS or flower filter in TC.
+The OVS or TC flower layer must set the tunnel information in SKB dst field before
+sending packet buffer to the bareudp device for transmission. On reception the
+bareudp device extracts and stores the tunnel information in SKB dst field before
+passing the packet buffer to the network stack.

+Devlink Flash
+=============
+
+The ``devlink-flash`` API allows updating device firmware. It replaces the
+older ``ethtool-flash`` mechanism, and doesn't require taking any
+networking locks in the kernel to perform the flash update. Example use::
+
+  $ devlink dev flash pci/0000:05:00.0 file flash-boot.bin
+
+Note that the file name is a path relative to the firmware loading path
+(usually ``/lib/firmware/``). Drivers may send status updates to inform
+user space about the progress of the update operation.
+
+Firmware Loading
+================
+
+Devices which require firmware to operate usually store it in non-volatile
+memory on the board, e.g. flash. Some devices store only basic firmware on
+the board, and the driver loads the rest from disk during probing.
+``devlink-info`` allows users to query firmware information (loaded
+components and versions).
+
+In other cases the device can both store the image on the board, load from
+disk, or automatically flash a new image from disk. The ``fw_load_policy``
+devlink parameter can be used to control this behavior
+(:ref:`Documentation/networking/devlink/devlink-params.rst <devlink_params_generic>`).
+
+On-disk firmware files are usually stored in ``/lib/firmware/``.
+
+Firmware Version Management
+===========================
+
+Drivers are expected to implement ``devlink-flash`` and ``devlink-info``
+functionality, which together allow for implementing vendor-independent
+automated firmware update facilities.
+
+``devlink-info`` exposes the ``driver`` name and three version groups
+(``fixed``, ``running``, ``stored``).

+The ``driver`` attribute and ``fixed`` group identify the specific device
+design, e.g. for looking up applicable firmware updates. This is why
+``serial_number`` is not part of the ``fixed`` versions (even though it
+is fixed) - ``fixed`` versions should identify the design, not a single
+device.
+
+``running`` and ``stored`` firmware versions identify the firmware running
+on the device, and firmware which will be activated after reboot or device
+reset.
+
+The firmware update agent is supposed to be able to follow this simple
+algorithm to update firmware contents, regardless of the device vendor:
+
+.. code-block:: sh
+
+  # Get unique HW design identifier
+  $hw_id = devlink-dev-info['fixed']
+
+  # Find out which FW flash we want to use for this NIC
+  $want_flash_vers = some-db-backed.lookup($hw_id, 'flash')
+
+  # Update flash if necessary
+  if $want_flash_vers != devlink-dev-info['stored']:
+      $file = some-db-backed.download($hw_id, 'flash')
+      devlink-dev-flash($file)
+
+  # Find out the expected overall firmware versions
+  $want_fw_vers = some-db-backed.lookup($hw_id, 'all')
+
+  # Update on-disk file if necessary
+  if $want_fw_vers != devlink-dev-info['running']:
+      $file = some-db-backed.download($hw_id, 'disk')
+      write($file, '/lib/firmware/')
+
+  # Try device reset, if available
+  if $want_fw_vers != devlink-dev-info['running']:
+     devlink-reset()
+
+  # Reboot, if reset wasn't enough
+  if $want_fw_vers != devlink-dev-info['running']:
+     reboot()
+
+Note that each reference to ``devlink-dev-info`` in this pseudo-code
+is expected to fetch up-to-date information from the kernel.
+
+For the convenience of identifying firmware files some vendors add
+``bundle_id`` information to the firmware versions. This meta-version covers
+multiple per-component versions and can be used e.g. in firmware file names
+(all component versions could get rather long.)

+ - name the per component FW versions (as opposed to the crowded ethtool

+
+``devlink-info`` supports reporting multiple types of objects. Reporting driver
+versions is generally discouraged - here, and via any other Linux API.
+
+.. list-table:: List of top level info objects
    :widths: 5 95
 
-   * - Type
+   * - Name
      - Description
+   * - ``driver``
+     - Name of the currently used device driver, also available through sysfs.
+
+   * - ``serial_number``
+     - Serial number of the device.
+
+       This is usually the serial number of the ASIC, also often available
+       in PCI config space of the device in the *Device Serial Number*
+       capability.
+
+       The serial number should be unique per physical device.
+       Sometimes the serial number of the device is only 48 bits long (the
+       length of the Ethernet MAC address), and since PCI DSN is 64 bits long
+       devices pad or encode additional information into the serial number.
+       One example is adding port ID or PCI interface ID in the extra two bytes.
+       Drivers should make sure to strip or normalize any such padding
+       or interface ID, and report only the part of the serial number
+       which uniquely identifies the hardware. In other words serial number
+       reported for two ports of the same device or on two hosts of
+       a multi-host device should be identical.
+
+       .. note:: ``devlink-info`` API should be extended with a new field
+	  if devices want to report board/product serial number (often
+	  reported in PCI *Vital Product Data* capability).
+
    * - ``fixed``
-     - Represents fixed versions, which cannot change. For example,
+     - Group for hardware identifiers, and versions of components
+       which are not field-updatable.
+
+       Versions in this section identify the device design. For example,
        component identifiers or the board version reported in the PCI VPD.
+       Data in ``devlink-info`` should be broken into the smallest logical
+       components, e.g. PCI VPD may concatenate various information
+       to form the Part Number string, while in ``devlink-info`` all parts
+       should be reported as separate items.
+
+       This group must not contain any frequently changing identifiers,
+       such as serial numbers. See
+       :ref:`Documentation/networking/devlink/devlink-flash.rst <devlink_flash>`
+       to understand why.
+
    * - ``running``
-     - Represents the version of the currently running component. For
-       example the running version of firmware. These versions generally
-       only update after a reboot.
+     - Group for information about currently running software/firmware.
+       These versions often only update after a reboot, sometimes device reset.
+
    * - ``stored``
-     - Represents the version of a component as stored, such as after a
-       flash update. Stored values should update to reflect changes in the
-       flash even if a reboot has not yet occurred.
+     - Group for software/firmware versions in device flash.
+
+       Stored values must update to reflect changes in the flash even
+       if reboot has not yet occurred. If device is not capable of updating
+       ``stored`` versions when new software is flashed, it must not report
+       them.
+
+Each version can be reported at most once in each version group. Firmware
+components stored on the flash should feature in both the ``running`` and
+``stored`` sections, if device is capable of reporting ``stored`` versions
+(see :ref:`Documentation/networking/devlink/devlink-flash.rst <devlink_flash>`).
+In case software/firmware components are loaded from the disk (e.g.
+``/lib/firmware``) only the running version should be reported via
+the kernel API.
 
 Generic Versions
 ================
 
 It is expected that drivers use the following generic names for exporting
-version information. Other information may be exposed using driver-specific
-names, but these should be documented in the driver-specific file.

+driver authors should consult existing driver-specific versions and attempt
+reuse. As last resort, if a component is truly unique, using driver-specific
+names is allowed, but these should be documented in the driver-specific file.
+
+All versions should try to use the following terminology:

+   :widths: 10 90
+
+   * - Name
+     - Description
+   * - ``id``, ``revision``
+     - Identifiers of designs and revision, mostly used for hardware versions.
+
+   * - ``api``
+     - Version of API between components. API items are usually of limited
+       value to the user, and can be inferred from other versions by the vendor,
+       so adding API versions is generally discouraged as noise.
+
+   * - ``bundle_id``
+     - Identifier of a distribution package which was flashed onto the device.
+       This is an attribute of a firmware package which covers multiple versions
+       for ease of managing firmware images (see
+       :ref:`Documentation/networking/devlink/devlink-flash.rst <devlink_flash>`).
+
+       ``bundle_id`` can appear in both ``running`` and ``stored`` versions,
+       but it must not be reported if any of the components covered by the
+       ``bundle_id`` was changed and no longer matches the version from

+Packet Trap Policers
+====================
+
+As previously explained, the underlying device can trap certain packets to the
+CPU for processing. In most cases, the underlying device is capable of handling
+packet rates that are several orders of magnitude higher compared to those that
+can be handled by the CPU.
+
+Therefore, in order to prevent the underlying device from overwhelming the CPU,
+devices usually include packet trap policers that are able to police the
+trapped packets to rates that can be handled by the CPU.
+
+The ``devlink-trap`` mechanism allows capable device drivers to register their
+supported packet trap policers with ``devlink``. The device driver can choose
+to associate these policers with supported packet trap groups (see
+:ref:`Generic-Packet-Trap-Groups`) during its initialization, thereby exposing
+its default control plane policy to user space.
+
+Device drivers should allow user space to change the parameters of the policers
+(e.g., rate, burst size) as well as the association between the policers and
+trap groups by implementing the relevant callbacks.
+
+If possible, device drivers should implement a callback that allows user space
+to retrieve the number of packets that were dropped by the policer because its
+configured policy was violated.

+if userspace needs them (most likely only ethtool for backward compatibility),

+kernel reply (can be suppressed by ``ETHTOOL_FLAG_OMIT_REPLY`` flag in request
+header) informs client about the actual result. ``ETHTOOL_A_FEATURES_WANTED``
+reports the difference between client request and actual result: mask consists
+of bits which differ between requested features and result (dev->features

+``ETHTOOL_A_PRIVFLAGS_FLAGS`` is a bitset with values of device private flags.
+These flags are defined by driver, their number and names (and also meaning)
+are device dependent. For compact bitset format, names can be retrieved as
+``ETH_SS_PRIV_FLAGS`` string set. If verbose bitset format is requested,

+Page Pool API
+=============
+
+The page_pool allocator is optimized for the XDP mode that uses one frame
+per-page, but it can fallback on the regular page allocator APIs.
+
+Basic use involves replacing alloc_pages() calls with the
+page_pool_alloc_pages() call.  Drivers should use page_pool_dev_alloc_pages()
+replacing dev_alloc_pages().
+
+API keeps track of inflight pages, in order to let API user know
+when it is safe to free a page_pool object.  Thus, API users
+must run page_pool_release_page() when a page is leaving the page_pool or
+call page_pool_put_page() where appropriate in order to maintain correct
+accounting.
+
+API user must call page_pool_put_page() once on a page, as it
+will either recycle the page, or in case of refcnt > 1, it will
+release the DMA mapping and inflight state accounting.

+API interface
+=============
+The number of pools created **must** match the number of hardware queues
+unless hardware restrictions make that impossible. This would otherwise beat the
+purpose of page pool, which is allocate pages fast from cache without locking.
+This lockless guarantee naturally comes from running under a NAPI softirq.
+The protection doesn't strictly have to be NAPI, any guarantee that allocating
+a page will cause no race conditions is enough.
+
+* page_pool_create(): Create a pool.
+    * flags:      PP_FLAG_DMA_MAP, PP_FLAG_DMA_SYNC_DEV
+    * order:      2^order pages on allocation
+    * pool_size:  size of the ptr_ring
+    * nid:        preferred NUMA node for allocation
+    * dev:        struct device. Used on DMA operations
+    * dma_dir:    DMA direction
+    * max_len:    max DMA sync memory size
+    * offset:     DMA address offset
+
+* page_pool_put_page(): The outcome of this depends on the page refcnt. If the
+  driver bumps the refcnt > 1 this will unmap the page. If the page refcnt is 1
+  the allocator owns the page and will try to recycle it in one of the pool
+  caches. If PP_FLAG_DMA_SYNC_DEV is set, the page will be synced for_device
+  using dma_sync_single_range_for_device().
+
+* page_pool_put_full_page(): Similar to page_pool_put_page(), but will DMA sync
+  for the entire memory area configured in area pool->max_len.
+
+* page_pool_recycle_direct(): Similar to page_pool_put_full_page() but caller
+  must guarantee safe context (e.g NAPI), since it will recycle the page
+  directly into the pool fast cache.
+
+* page_pool_release_page(): Unmap the page (if mapped) and account for it on
+  inflight counters.
+
+* page_pool_dev_alloc_pages(): Get a page from the page allocator or page_pool
+  caches.
+
+* page_pool_get_dma_addr(): Retrieve the stored DMA address.
+
+* page_pool_get_dma_dir(): Retrieve the stored DMA direction.

+(effective) target value.  The aggregated target value is updated with changes

 Note: the aggregated target value is implemented as an atomic variable so that
 reading the aggregated value does not require any locking mechanism.

+			       ANNOUNCEMENT

+			      1 February 1996
+
+			  ADDITIONAL ANNOUNCEMENT
+	       BusLogic FlashPoint LW/BT-958 Upgrade Program
+			       14 June 1996
+
+  Ever since its introduction last October, the BusLogic FlashPoint LT has
+  been problematic for members of the Linux community, in that no Linux
+  drivers have been available for this new Ultra SCSI product.  Despite its
+  officially being positioned as a desktop workstation product, and not being
+  particularly well suited for a high performance multitasking operating
+  system like Linux, the FlashPoint LT has been touted by computer system
+  vendors as the latest thing, and has been sold even on many of their high
+  end systems, to the exclusion of the older MultiMaster products.  This has
+  caused grief for many people who inadvertently purchased a system expecting
+  that all BusLogic SCSI Host Adapters were supported by Linux, only to
+  discover that the FlashPoint was not supported and would not be for quite
+  some time, if ever.
+
+  After this problem was identified, BusLogic contacted its major OEM
+  customers to make sure the BT-946C/956C MultiMaster cards would still be
+  made available, and that Linux users who mistakenly ordered systems with
+  the FlashPoint would be able to upgrade to the BT-946C.  While this helped
+  many purchasers of new systems, it was only a partial solution to the
+  overall problem of FlashPoint support for Linux users.  It did nothing to
+  assist the people who initially purchased a FlashPoint for a supported
+  operating system and then later decided to run Linux, or those who had
+  ended up with a FlashPoint LT, believing it was supported, and were unable
+  to return it.
+
+  In the middle of December, I asked to meet with BusLogic's senior
+  management to discuss the issues related to Linux and free software support
+  for the FlashPoint.  Rumors of varying accuracy had been circulating
+  publicly about BusLogic's attitude toward the Linux community, and I felt
+  it was best that these issues be addressed directly.  I sent an email
+  message after 11pm one evening, and the meeting took place the next
+  afternoon.  Unfortunately, corporate wheels sometimes grind slowly,
+  especially when a company is being acquired, and so it's taken until now
+  before the details were completely determined and a public statement could
+  be made.
+
+  BusLogic is not prepared at this time to release the information necessary
+  for third parties to write drivers for the FlashPoint.  The only existing
+  FlashPoint drivers have been written directly by BusLogic Engineering, and
+  there is no FlashPoint documentation sufficiently detailed to allow outside
+  developers to write a driver without substantial assistance.  While there
+  are people at BusLogic who would rather not release the details of the
+  FlashPoint architecture at all, that debate has not yet been settled either
+  way.  In any event, even if documentation were available today it would
+  take quite a while for a usable driver to be written, especially since I'm
+  not convinced that the effort required would be worthwhile.
+
+  However, BusLogic does remain committed to providing a high performance
+  SCSI solution for the Linux community, and does not want to see anyone left
+  unable to run Linux because they have a Flashpoint LT.  Therefore, BusLogic
+  has put in place a direct upgrade program to allow any Linux user worldwide
+  to trade in their FlashPoint LT for the new BT-948 MultiMaster PCI Ultra
+  SCSI Host Adapter.  The BT-948 is the Ultra SCSI successor to the BT-946C
+  and has all the best features of both the BT-946C and FlashPoint LT,
+  including smart termination and a flash PROM for easy firmware updates, and
+  is of course compatible with the present Linux driver.  The price for this
+  upgrade has been set at US $45 plus shipping and handling, and the upgrade
+  program will be administered through BusLogic Technical Support, which can
+  be reached by electronic mail at techsup@buslogic.com, by Voice at +1 408
+  654-0760, or by FAX at +1 408 492-1542.
+
+  As of 14 June 1996, the original BusLogic FlashPoint LT to BT-948 upgrade
+  program has now been extended to encompass the FlashPoint LW Wide Ultra
+  SCSI Host Adapter.  Any Linux user worldwide may trade in their FlashPoint
+  LW (BT-950) for a BT-958 MultiMaster PCI Ultra SCSI Host Adapter.  The
+  price for this upgrade has been set at US $65 plus shipping and handling.
+
+  I was a beta test site for the BT-948/958, and versions 1.2.1 and 1.3.1 of
+  my BusLogic driver already included latent support for the BT-948/958.
+  Additional cosmetic support for the Ultra SCSI MultiMaster cards was added
+  subsequent releases.  As a result of this cooperative testing process,
+  several firmware bugs were found and corrected.  My heavily loaded Linux
+  test system provided an ideal environment for testing error recovery
+  processes that are much more rarely exercised in production systems, but
+  are crucial to overall system stability.  It was especially convenient
+  being able to work directly with their firmware engineer in demonstrating
+  the problems under control of the firmware debugging environment; things
+  sure have come a long way since the last time I worked on firmware for an
+  embedded system.  I am presently working on some performance testing and
+  expect to have some data to report in the not too distant future.
+
+  BusLogic asked me to send this announcement since a large percentage of the
+  questions regarding support for the FlashPoint have either been sent to me
+  directly via email, or have appeared in the Linux newsgroups in which I
+  participate.  To summarize, BusLogic is offering Linux users an upgrade
+  from the unsupported FlashPoint LT (BT-930) to the supported BT-948 for US
+  $45 plus shipping and handling, or from the unsupported FlashPoint LW
+  (BT-950) to the supported BT-958 for $65 plus shipping and handling.

+  654-0760 to take advantage of their offer.

-			       ANNOUNCEMENT
-	       BusLogic FlashPoint LT/BT-948 Upgrade Program
-			      1 February 1996
-
-			  ADDITIONAL ANNOUNCEMENT
-	       BusLogic FlashPoint LW/BT-958 Upgrade Program
-			       14 June 1996
-
-Ever since its introduction last October, the BusLogic FlashPoint LT has
-been problematic for members of the Linux community, in that no Linux
-drivers have been available for this new Ultra SCSI product.  Despite its
-officially being positioned as a desktop workstation product, and not being
-particularly well suited for a high performance multitasking operating
-system like Linux, the FlashPoint LT has been touted by computer system
-vendors as the latest thing, and has been sold even on many of their high
-end systems, to the exclusion of the older MultiMaster products.  This has
-caused grief for many people who inadvertently purchased a system expecting
-that all BusLogic SCSI Host Adapters were supported by Linux, only to
-discover that the FlashPoint was not supported and would not be for quite
-some time, if ever.
-
-After this problem was identified, BusLogic contacted its major OEM
-customers to make sure the BT-946C/956C MultiMaster cards would still be
-made available, and that Linux users who mistakenly ordered systems with
-the FlashPoint would be able to upgrade to the BT-946C.  While this helped
-many purchasers of new systems, it was only a partial solution to the
-overall problem of FlashPoint support for Linux users.  It did nothing to
-assist the people who initially purchased a FlashPoint for a supported
-operating system and then later decided to run Linux, or those who had
-ended up with a FlashPoint LT, believing it was supported, and were unable
-to return it.
-
-In the middle of December, I asked to meet with BusLogic's senior
-management to discuss the issues related to Linux and free software support
-for the FlashPoint.  Rumors of varying accuracy had been circulating
-publicly about BusLogic's attitude toward the Linux community, and I felt
-it was best that these issues be addressed directly.  I sent an email
-message after 11pm one evening, and the meeting took place the next
-afternoon.  Unfortunately, corporate wheels sometimes grind slowly,
-especially when a company is being acquired, and so it's taken until now
-before the details were completely determined and a public statement could
-be made.
-
-BusLogic is not prepared at this time to release the information necessary
-for third parties to write drivers for the FlashPoint.  The only existing
-FlashPoint drivers have been written directly by BusLogic Engineering, and
-there is no FlashPoint documentation sufficiently detailed to allow outside
-developers to write a driver without substantial assistance.  While there
-are people at BusLogic who would rather not release the details of the
-FlashPoint architecture at all, that debate has not yet been settled either
-way.  In any event, even if documentation were available today it would
-take quite a while for a usable driver to be written, especially since I'm
-not convinced that the effort required would be worthwhile.
-
-However, BusLogic does remain committed to providing a high performance
-SCSI solution for the Linux community, and does not want to see anyone left
-unable to run Linux because they have a Flashpoint LT.  Therefore, BusLogic
-has put in place a direct upgrade program to allow any Linux user worldwide
-to trade in their FlashPoint LT for the new BT-948 MultiMaster PCI Ultra
-SCSI Host Adapter.  The BT-948 is the Ultra SCSI successor to the BT-946C
-and has all the best features of both the BT-946C and FlashPoint LT,
-including smart termination and a flash PROM for easy firmware updates, and
-is of course compatible with the present Linux driver.  The price for this
-upgrade has been set at US $45 plus shipping and handling, and the upgrade
-program will be administered through BusLogic Technical Support, which can
-be reached by electronic mail at techsup@buslogic.com, by Voice at +1 408
-654-0760, or by FAX at +1 408 492-1542.
-
-As of 14 June 1996, the original BusLogic FlashPoint LT to BT-948 upgrade
-program has now been extended to encompass the FlashPoint LW Wide Ultra
-SCSI Host Adapter.  Any Linux user worldwide may trade in their FlashPoint
-LW (BT-950) for a BT-958 MultiMaster PCI Ultra SCSI Host Adapter.  The
-price for this upgrade has been set at US $65 plus shipping and handling.
-
-I was a beta test site for the BT-948/958, and versions 1.2.1 and 1.3.1 of
-my BusLogic driver already included latent support for the BT-948/958.
-Additional cosmetic support for the Ultra SCSI MultiMaster cards was added
-subsequent releases.  As a result of this cooperative testing process,
-several firmware bugs were found and corrected.  My heavily loaded Linux
-test system provided an ideal environment for testing error recovery
-processes that are much more rarely exercised in production systems, but
-are crucial to overall system stability.  It was especially convenient
-being able to work directly with their firmware engineer in demonstrating
-the problems under control of the firmware debugging environment; things
-sure have come a long way since the last time I worked on firmware for an
-embedded system.  I am presently working on some performance testing and
-expect to have some data to report in the not too distant future.
-
-BusLogic asked me to send this announcement since a large percentage of the
-questions regarding support for the FlashPoint have either been sent to me
-directly via email, or have appeared in the Linux newsgroups in which I
-participate.  To summarize, BusLogic is offering Linux users an upgrade
-from the unsupported FlashPoint LT (BT-930) to the supported BT-948 for US
-$45 plus shipping and handling, or from the unsupported FlashPoint LW
-(BT-950) to the supported BT-958 for $65 plus shipping and handling.
-Contact BusLogic Technical Support at techsup@buslogic.com or +1 408
-654-0760 to take advantage of their offer.

+WorkBiT NinjaSCSI-3/32Bi driver for Linux
+=========================================
+
+1. Comment
+==========
+
+This is Workbit corp.'s(http://www.workbit.co.jp/) NinjaSCSI-3
+for Linux.
+
+2. My Linux environment
+=======================
+
+:Linux kernel: 2.4.7 / 2.2.19
+:pcmcia-cs:    3.1.27
+:gcc:          gcc-2.95.4
+:PC card:      I-O data PCSC-F (NinjaSCSI-3),
+               I-O data CBSC-II in 16 bit mode (NinjaSCSI-32Bi)
+:SCSI device:  I-O data CDPS-PX24 (CD-ROM drive),
+               Media Intelligent MMO-640GT (Optical disk drive)
+
+3. Install
+==========
+
+(a) Check your PC card is true "NinjaSCSI-3" card.
+
+    If you installed pcmcia-cs already, pcmcia reports your card as UNKNOWN
+    card, and write ["WBT", "NinjaSCSI-3", "R1.0"] or some other string to
+    your console or log file.
+
+    You can also use "cardctl" program (this program is in pcmcia-cs source
+    code) to get more info.
+
+    ::
+
+	# cat /var/log/messages
+	...
+	Jan  2 03:45:06 lindberg cardmgr[78]: unsupported card in socket 1
+	Jan  2 03:45:06 lindberg cardmgr[78]:   product info: "WBT", "NinjaSCSI-3", "R1.0"
+	...
+	# cardctl ident
+	Socket 0:
+	  no product info available
+	Socket 1:
+	  product info: "IO DATA", "CBSC16       ", "1"
+
+
+(b) Get the Linux kernel source, and extract it to /usr/src.
+    Because the NinjaSCSI driver requires some SCSI header files in Linux 
+    kernel source, I recommend rebuilding your kernel; this eliminates 
+    some versioning problems.
+
+    ::
+
+	$ cd /usr/src
+	$ tar -zxvf linux-x.x.x.tar.gz
+	$ cd linux
+	$ make config
+	...
+
+(c) If you use this driver with Kernel 2.2, unpack pcmcia-cs in some directory
+    and make & install. This driver requires the pcmcia-cs header file.
+
+    ::
+
+	$ cd /usr/src
+	$ tar zxvf cs-pcmcia-cs-3.x.x.tar.gz
+	...
+
+(d) Extract this driver's archive somewhere, and edit Makefile, then do make::
+
+	$ tar -zxvf nsp_cs-x.x.tar.gz
+	$ cd nsp_cs-x.x
+	$ emacs Makefile
+	...
+	$ make
+
+(e) Copy nsp_cs.ko to suitable place, like /lib/modules/<Kernel version>/pcmcia/ .
+
+(f) Add these lines to /etc/pcmcia/config .
+
+    If you use pcmcia-cs-3.1.8 or later, we can use "nsp_cs.conf" file.
+    So, you don't need to edit file. Just copy to /etc/pcmcia/ .
+
+    ::
+
+	device "nsp_cs"
+	  class "scsi" module "nsp_cs"

+(f) Start (or restart) pcmcia-cs::
+
+	# /etc/rc.d/rc.pcmcia start        (BSD style)

+4. History
+==========
+
+See README.nin_cs .
+
+5. Caution
+==========
+
+If you eject card when doing some operation for your SCSI device or suspend
+your computer, you encount some *BAD* error like disk crash.
+
+It works good when I using this driver right way. But I'm not guarantee
+your data. Please backup your data when you use this driver.
+
+6. Known Bugs
+=============
+
+In 2.4 kernel, you can't use 640MB Optical disk. This error comes from
+high level SCSI driver.
+
+7. Testing
+==========
+
+Please send me some reports(bug reports etc..) of this software.
+When you send report, please tell me these or more.

+2. Version History
+==================
+
+
+ * 3.0	  (December 1st, 2005)
+	- Updated driver to use SCSI transport class infrastructure
+	- Upported sequencer and core fixes from adaptec released
+	  version 2.0.15 of the driver.
+
+ * 1.3.11 (July 11, 2003)
+        - Fix several deadlock issues.
+        - Add 29320ALP and 39320B Id's.
+
+ * 1.3.10 (June 3rd, 2003)
+        - Align the SCB_TAG field on a 16byte boundary.  This avoids
+          SCB corruption on some PCI-33 busses.
+        - Correct non-zero luns on Rev B. hardware.
+        - Update for change in 2.5.X SCSI proc FS interface.
+        - When negotiation async via an 8bit WDTR message, send
+          an SDTR with an offset of 0 to be sure the target
+          knows we are async.  This works around a firmware defect
+          in the Quantum Atlas 10K.
+        - Implement controller suspend and resume.
+        - Clear PCI error state during driver attach so that we
+          don't disable memory mapped I/O due to a stray write
+          by some other driver probe that occurred before we
+          claimed the controller.
+
+ * 1.3.9 (May 22nd, 2003)
+        - Fix compiler errors.
+        - Remove S/G splitting for segments that cross a 4GB boundary.
+          This is guaranteed not to happen in Linux.
+        - Add support for scsi_report_device_reset() found in
+          2.5.X kernels.
+        - Add 7901B support.
+        - Simplify handling of the packetized lun Rev A workaround.
+        - Correct and simplify handling of the ignore wide residue
+          message.  The previous code would fail to report a residual
+          if the transaction data length was even and we received
+          an IWR message.
+
+ * 1.3.8 (April 29th, 2003)
+        - Fix types accessed via the command line interface code.
+        - Perform a few firmware optimizations.
+        - Fix "Unexpected PKT busfree" errors.
+        - Use a sequencer interrupt to notify the host of
+          commands with bad status.  We defer the notification
+          until there are no outstanding selections to ensure
+          that the host is interrupted for as short a time as
+          possible.
+        - Remove pre-2.2.X support.
+        - Add support for new 2.5.X interrupt API.

+
+4. Additional Notes
+===================
+
+4.1. Known/Unresolved or FYI Issues
+-----------------------------------
+
+        * Under SuSE Linux Enterprise 7, the driver may fail to operate
+          correctly due to a problem with PCI interrupt routing in the
+          Linux kernel.  Please contact SuSE for an updated Linux
+          kernel.
+
+4.2. Third-Party Compatibility Issues
+-------------------------------------
+
+        * Adaptec only supports Ultra320 hard drives running
+          the latest firmware available. Please check with
+          your hard drive manufacturer to ensure you have the
+          latest version.
+
+4.3. Operating System or Technology Limitations
+-----------------------------------------------
+
+        * PCI Hot Plug is untested and may cause the operating system
+          to stop responding.
+        * Luns that are not numbered contiguously starting with 0 might not
+          be automatically probed during system startup.  This is a limitation
+          of the OS.  Please contact your Linux vendor for instructions on
+          manually probing non-contiguous luns.
+        * Using the Driver Update Disk version of this package during OS
+          installation under RedHat might result in two versions of this
+          driver being installed into the system module directory.  This
+          might cause problems with the /sbin/mkinitrd program and/or
+          other RPM packages that try to install system modules.  The best
+          way to correct this once the system is running is to install
+          the latest RPM package version of this driver, available from
+          http://www.adaptec.com.

-2. Version History
-
-   3.0	  (December 1st, 2005)
-	- Updated driver to use SCSI transport class infrastructure
-	- Upported sequencer and core fixes from adaptec released
-	  version 2.0.15 of the driver.
-
-   1.3.11 (July 11, 2003)
-        - Fix several deadlock issues.
-        - Add 29320ALP and 39320B Id's.
-
-   1.3.10 (June 3rd, 2003)
-        - Align the SCB_TAG field on a 16byte boundary.  This avoids
-          SCB corruption on some PCI-33 busses.
-        - Correct non-zero luns on Rev B. hardware.
-        - Update for change in 2.5.X SCSI proc FS interface.
-        - When negotiation async via an 8bit WDTR message, send
-          an SDTR with an offset of 0 to be sure the target
-          knows we are async.  This works around a firmware defect
-          in the Quantum Atlas 10K.
-        - Implement controller suspend and resume.
-        - Clear PCI error state during driver attach so that we
-          don't disable memory mapped I/O due to a stray write
-          by some other driver probe that occurred before we
-          claimed the controller.
-
-   1.3.9 (May 22nd, 2003)
-        - Fix compiler errors.
-        - Remove S/G splitting for segments that cross a 4GB boundary.

-          2.5.X kernels.
-        - Add 7901B support.
-        - Simplify handling of the packetized lun Rev A workaround.
-        - Correct and simplify handling of the ignore wide residue
-          message.  The previous code would fail to report a residual
-          if the transaction data length was even and we received
-          an IWR message.
-
-   1.3.8 (April 29th, 2003)
-        - Fix types accessed via the command line interface code.
-        - Perform a few firmware optimizations.
-        - Fix "Unexpected PKT busfree" errors.
-        - Use a sequencer interrupt to notify the host of
-          commands with bad status.  We defer the notification
-          until there are no outstanding selections to ensure
-          that the host is interrupted for as short a time as
-          possible.
-        - Remove pre-2.2.X support.
-        - Add support for new 2.5.X interrupt API.
-        - Correct big-endian architecture support.
-
-   1.3.7 (April 16th, 2003)
-        - Use del_timer_sync() to ensure that no timeouts
-          are pending during controller shutdown.
-        - For pre-2.5.X kernels, carefully adjust our segment
-          list size to avoid SCSI malloc pool fragmentation.
-        - Cleanup channel display in our /proc output.
-        - Workaround duplicate device entries in the mid-layer
-          device list during add-single-device.

-        - Correct a double free in the Domain Validation code.
-        - Correct a reference to free'ed memory during controller
-          shutdown.
-        - Reset the bus on an SE->LVD change.  This is required
-          to reset our transceivers.
-
-   1.3.5 (March 24th, 2003)

-          to stop responding.
-        * Luns that are not numbered contiguously starting with 0 might not
-          be automatically probed during system startup.  This is a limitation
-          of the OS.  Please contact your Linux vendor for instructions on
-          manually probing non-contiguous luns.
-        * Using the Driver Update Disk version of this package during OS
-          installation under RedHat might result in two versions of this
-          driver being installed into the system module directory.  This
-          might cause problems with the /sbin/mkinitrd program and/or
-          other RPM packages that try to install system modules.  The best
-          way to correct this once the system is running is to install
-          the latest RPM package version of this driver, available from
-          http://www.adaptec.com.

+   1. No BIOS support
+   2. DEC21050 PCI-PCI bridge with multiple controller chips on secondary bus
+   3. DEC2115X PCI-PCI bridge with multiple controller chips on secondary bus
+   4. All three SCSI connectors may be used simultaneously without
+      SCSI "stub" effects.
+
+2. Version History
+==================
+
+   * 7.0	  (4th August, 2005)
+	- Updated driver to use SCSI transport class infrastructure
+	- Upported sequencer and core fixes from last adaptec released
+	  version of the driver.
+
+   * 6.2.36 (June 3rd, 2003)
+        - Correct code that disables PCI parity error checking.
+        - Correct and simplify handling of the ignore wide residue
+          message.  The previous code would fail to report a residual
+          if the transaction data length was even and we received
+          an IWR message.
+        - Add support for the 2.5.X EISA framework.
+        - Update for change in 2.5.X SCSI proc FS interface.
+        - Correct Domain Validation command-line option parsing.
+        - When negotiation async via an 8bit WDTR message, send
+          an SDTR with an offset of 0 to be sure the target
+          knows we are async.  This works around a firmware defect
+          in the Quantum Atlas 10K.
+        - Clear PCI error state during driver attach so that we
+          don't disable memory mapped I/O due to a stray write
+          by some other driver probe that occurred before we
+          claimed the controller.
+
+   * 6.2.35 (May 14th, 2003)
+        - Fix a few GCC 3.3 compiler warnings.
+        - Correct operation on EISA Twin Channel controller.
+        - Add support for 2.5.X's scsi_report_device_reset().
+
+   * 6.2.34 (May 5th, 2003)
+        - Fix locking regression introduced in 6.2.29 that
+          could cause a lock order reversal between the io_request_lock
+          and our per-softc lock.  This was only possible on RH9,
+          SuSE, and kernel.org 2.4.X kernels.
+
+   * 6.2.33 (April 30th, 2003)
+        - Dynamically disable PCI parity error reporting after
+          10 errors are reported to the user.  These errors are
+          the result of some other device issuing PCI transactions
+          with bad parity.  Once the user has been informed of the
+          problem, continuing to report the errors just degrades
+          our performance.
+
+   * 6.2.32 (March 28th, 2003)
+        - Dynamically sized S/G lists to avoid SCSI malloc
+          pool fragmentation and SCSI mid-layer deadlock.
+
+   * 6.2.28 (January 20th, 2003)
+        - Domain Validation Fixes
+        - Add ability to disable PCI parity error checking.
+        - Enhanced Memory Mapped I/O probe
+
+   * 6.2.20 (November 7th, 2002)
+        - Added Domain Validation.
+
+3. Command Line Options
+=======================
+
+
+    .. Warning::
+
+                 ALTERING OR ADDING THESE DRIVER PARAMETERS
+                 INCORRECTLY CAN RENDER YOUR SYSTEM INOPERABLE.
+                 USE THEM WITH CAUTION.
+
+   Put a .conf file in the /etc/modprobe.d directory and add/edit a
+   line containing ``options aic7xxx aic7xxx=[command[,command...]]`` where
+   ``command`` is one or more of the following:
+
+verbose
+
+    :Definition: enable additional informative messages during driver operation.
+    :Possible Values: This option is a flag
+    :Default Value: disabled
+
+
+debug:[value]
+
+    :Definition: Enables various levels of debugging information
+    :Possible Values: 0x0000 = no debugging, 0xffff = full debugging
+    :Default Value: 0x0000
+
+no_probe
+
+probe_eisa_vl
+
+    :Definition: Do not probe for EISA/VLB controllers.
+		 This is a toggle.  If the driver is compiled
+		 to not probe EISA/VLB controllers by default,
+		 specifying "no_probe" will enable this probing.
+		 If the driver is compiled to probe EISA/VLB
+		 controllers by default, specifying "no_probe"
+		 will disable this probing.
+
+    :Possible Values: This option is a toggle
+    :Default Value: EISA/VLB probing is disabled by default.
+
+pci_parity
+
+    :Definition: Toggles the detection of PCI parity errors.
+		 On many motherboards with VIA chipsets,
+		 PCI parity is not generated correctly on the
+		 PCI bus.  It is impossible for the hardware to
+		 differentiate between these "spurious" parity
+		 errors and real parity errors.  The symptom of
+		 this problem is a stream of the message::
+
+		    "scsi0:	Data Parity Error Detected during address or write data phase"
+

-
-2. Version History
-   7.0	  (4th August, 2005)
-	- Updated driver to use SCSI transport class infrastructure
-	- Upported sequencer and core fixes from last adaptec released
-	  version of the driver.
-   6.2.36 (June 3rd, 2003)
-        - Correct code that disables PCI parity error checking.
-        - Correct and simplify handling of the ignore wide residue
-          message.  The previous code would fail to report a residual
-          if the transaction data length was even and we received
-          an IWR message.
-        - Add support for the 2.5.X EISA framework.
-        - Update for change in 2.5.X SCSI proc FS interface.
-        - Correct Domain Validation command-line option parsing.
-        - When negotiation async via an 8bit WDTR message, send
-          an SDTR with an offset of 0 to be sure the target
-          knows we are async.  This works around a firmware defect
-          in the Quantum Atlas 10K.
-        - Clear PCI error state during driver attach so that we
-          don't disable memory mapped I/O due to a stray write
-          by some other driver probe that occurred before we
-          claimed the controller.
-
-   6.2.35 (May 14th, 2003)
-        - Fix a few GCC 3.3 compiler warnings.
-        - Correct operation on EISA Twin Channel controller.
-        - Add support for 2.5.X's scsi_report_device_reset().
-
-   6.2.34 (May 5th, 2003)
-        - Fix locking regression introduced in 6.2.29 that
-          could cause a lock order reversal between the io_request_lock
-          and our per-softc lock.  This was only possible on RH9,
-          SuSE, and kernel.org 2.4.X kernels.
-
-   6.2.33 (April 30th, 2003)
-        - Dynamically disable PCI parity error reporting after
-          10 errors are reported to the user.  These errors are
-          the result of some other device issuing PCI transactions
-          with bad parity.  Once the user has been informed of the
-          problem, continuing to report the errors just degrades
-          our performance.
-
-   6.2.32 (March 28th, 2003)
-        - Dynamically sized S/G lists to avoid SCSI malloc
-          pool fragmentation and SCSI mid-layer deadlock.
-
-   6.2.28 (January 20th, 2003)
-        - Domain Validation Fixes
-        - Add ability to disable PCI parity error checking.
-        - Enhanced Memory Mapped I/O probe
-
-   6.2.20 (November 7th, 2002)
-        - Added Domain Validation.

-        WARNING: ALTERING OR ADDING THESE DRIVER PARAMETERS
-                 INCORRECTLY CAN RENDER YOUR SYSTEM INOPERABLE.
-                 USE THEM WITH CAUTION. 
-
-   Put a .conf file in the /etc/modprobe.d directory and add/edit a
-   line containing 'options aic7xxx aic7xxx=[command[,command...]]' where
-   'command' is one or more of the following:
-   -----------------------------------------------------------------
-              Option: verbose
-          Definition: enable additional informative messages during
-                      driver operation.
-     Possible Values: This option is a flag
-       Default Value: disabled
-   -----------------------------------------------------------------
-              Option: debug:[value]
-          Definition: Enables various levels of debugging information
-     Possible Values: 0x0000 = no debugging, 0xffff = full debugging
-       Default Value: 0x0000
-   -----------------------------------------------------------------
-              Option: no_probe
-              Option: probe_eisa_vl
-          Definition: Do not probe for EISA/VLB controllers.
-                      This is a toggle.  If the driver is compiled
-                      to not probe EISA/VLB controllers by default,
-                      specifying "no_probe" will enable this probing.
-                      If the driver is compiled to probe EISA/VLB
-                      controllers by default, specifying "no_probe"
-                      will disable this probing.
-     Possible Values: This option is a toggle
-       Default Value: EISA/VLB probing is disabled by default.
-   -----------------------------------------------------------------
-              Option: pci_parity
-          Definition: Toggles the detection of PCI parity errors.
-                      On many motherboards with VIA chipsets,
-                      PCI parity is not generated correctly on the
-                      PCI bus.  It is impossible for the hardware to
-                      differentiate between these "spurious" parity
-                      errors and real parity errors.  The symptom of
-                      this problem is a stream of the message:
-    "scsi0: Data Parity Error Detected during address or write data phase"
-                      output by the driver.
-     Possible Values: This option is a toggle
-       Default Value: PCI Parity Error reporting is disabled
-   -----------------------------------------------------------------
-              Option: no_reset
-          Definition: Do not reset the bus during the initial probe
-                      phase
-     Possible Values: This option is a flag
-       Default Value: disabled
-   -----------------------------------------------------------------
-              Option: extended
-          Definition: Force extended translation on the controller
-     Possible Values: This option is a flag
-       Default Value: disabled
-   -----------------------------------------------------------------
-              Option: periodic_otag
-          Definition: Send an ordered tag periodically to prevent
-                      tag starvation.  Needed for some older devices
-     Possible Values: This option is a flag
-       Default Value: disabled
-   -----------------------------------------------------------------
-              Option: reverse_scan
-          Definition: Probe the scsi bus in reverse order, starting
-                      with target 15
-     Possible Values: This option is a flag
-       Default Value: disabled
-   -----------------------------------------------------------------
-              Option: global_tag_depth:[value]
-          Definition: Global tag depth for all targets on all busses.
-                      This option sets the default tag depth which
-                      may be selectively overridden vi the tag_info
-                      option.
-     Possible Values: 1 - 253
-       Default Value: 32
-   -----------------------------------------------------------------
-              Option: tag_info:{{value[,value...]}[,{value[,value...]}...]}
-          Definition: Set the per-target tagged queue depth on a
-                      per controller basis.  Both controllers and targets
-                      may be omitted indicating that they should retain
-                      the default tag depth.
-            Examples: tag_info:{{16,32,32,64,8,8,,32,32,32,32,32,32,32,32,32}
-                        On Controller 0
-                          specifies a tag depth of 16 for target 0
-                          specifies a tag depth of 64 for target 3
-                          specifies a tag depth of 8 for targets 4 and 5
-                          leaves target 6 at the default
-                          specifies a tag depth of 32 for targets 1,2,7-15
-                        All other targets retain the default depth.
-
-                      tag_info:{{},{32,,32}}
-                        On Controller 1
-                          specifies a tag depth of 32 for targets 0 and 2
-                        All other targets retain the default depth.
-                        
-     Possible Values: 1 - 253
-       Default Value: 32
-   -----------------------------------------------------------------
-              Option: seltime:[value]
-          Definition: Specifies the selection timeout value
-     Possible Values: 0 = 256ms, 1 = 128ms, 2 = 64ms, 3 = 32ms
-       Default Value: 0
-   -----------------------------------------------------------------
-              Option: dv: {value[,value...]} 
-          Definition: Set Domain Validation Policy on a per-controller basis.
-                      Controllers may be omitted indicating that

-**                            ARECA FIRMWARE SPEC
-*******************************************************************************
-**	Usage of IOP331 adapter
-**	(All In/Out is in IOP331's view)
-**	1. Message 0 --> InitThread message and return code
-**	2. Doorbell is used for RS-232 emulation
-**		inDoorBell :    bit0 -- data in ready
-**			(DRIVER DATA WRITE OK)
-**				bit1 -- data out has been read
-**			(DRIVER DATA READ OK)
-**		outDooeBell:    bit0 -- data out ready
-**			(IOP331 DATA WRITE OK)
-**				bit1 -- data in has been read
-**			(IOP331 DATA READ OK)
-**	3. Index Memory Usage
-**	offset 0xf00 : for RS232 out (request buffer)
-**	offset 0xe00 : for RS232 in  (scratch buffer)
-**	offset 0xa00 : for inbound message code message_rwbuffer
-**			(driver send to IOP331)
-**	offset 0xa00 : for outbound message code message_rwbuffer
-**			(IOP331 send to driver)
-**	4. RS-232 emulation
-**		Currently 128 byte buffer is used
-**			1st uint32_t : Data length (1--124)
-**			Byte 4--127  : Max 124 bytes of data
-**	5. PostQ
-**	All SCSI Command must be sent through postQ:
-**	(inbound queue port)	Request frame must be 32 bytes aligned
-**	#bit27--bit31 => flag for post ccb
-**	#bit0--bit26  => real address (bit27--bit31) of post arcmsr_cdb
-**		bit31 :
-**			0 : 256 bytes frame
-**			1 : 512 bytes frame
-**		bit30 :
-**			0 : normal request
-**			1 : BIOS request
-**		bit29 : reserved
-**		bit28 : reserved
-**		bit27 : reserved
-**  ---------------------------------------------------------------------------
-**	(outbount queue port)	Request reply
-**	#bit27--bit31
-**		=> flag for reply
-**	#bit0--bit26
-**		=> real address (bit27--bit31) of reply arcmsr_cdb
-**			bit31 : must be 0 (for this type of reply)
-**			bit30 : reserved for BIOS handshake
-**			bit29 : reserved
-**			bit28 :
-**			0 : no error, ignore AdapStatus/DevStatus/SenseData
-**			1 : Error, error code in AdapStatus/DevStatus/SenseData
-**			bit27 : reserved
-**	6. BIOS request
-**		All BIOS request is the same with request from PostQ
-**		Except :
-**			Request frame is sent from configuration space
-**		offset: 0x78 : Request Frame (bit30 == 1)
-**		offset: 0x18 : writeonly to generate
-**					IRQ to IOP331
-**		Completion of request:
-**			(bit30 == 0, bit28==err flag)
-**	7. Definition of SGL entry (structure)
-**	8. Message1 Out - Diag Status Code (????)
-**	9. Message0 message code :
-**		0x00 : NOP
-**		0x01 : Get Config
-**		->offset 0xa00 :for outbound message code message_rwbuffer

-**		FirmwareVersion DWORD <== Added for checking of
-**						new firmware capability
-**		0x02 : Set Config
-**		->offset 0xa00 :for inbound message code message_rwbuffer
-**		(driver send to IOP331)
-**		Signature             0x87974063(4)
-**		UPPER32 of Request Frame  (4)-->Driver Only
-**		0x03 : Reset (Abort all queued Command)
-**		0x04 : Stop Background Activity
-**		0x05 : Flush Cache
-**		0x06 : Start Background Activity
-**			(re-start if background is halted)

+=======
+
+The original linux driver was ported to Linux by Karen White while at
+Dell Computer.  It was ported from Bob Pasteur's (of DPT) original
+non-Linux driver.  Mark Salyzyn and Bob Pasteur consulted on the original
+driver.
+
+2.0 version of the driver by Deanna Bonds and Mark Salyzyn.
+
+History
+=======
+
+The driver was originally ported to linux version 2.0.34
+
+==== ==========================================================================
+V2.0 Rewrite of driver.  Re-architectured based on i2o subsystem.
+     This was the first full GPL version since the last version used
+     i2osig headers which were not GPL.  Developer Testing version.
+V2.1 Internal testing
+V2.2 First released version
+
+V2.3 Changes:
+
+     - Added Raptor Support
+     - Fixed bug causing system to hang under extreme load with
+     - management utilities running (removed GFP_DMA from kmalloc flags)
+
+V2.4 First version ready to be submitted to be embedded in the kernel
+
+     Changes:
+
+     - Implemented suggestions from Alan Cox
+     - Added calculation of resid for sg layer
+     - Better error handling
+     - Added checking underflow conditions
+     - Added DATAPROTECT checking
+     - Changed error return codes
+     - Fixed pointer bug in bus reset routine
+     - Enabled hba reset from ioctls (allows a FW flash to reboot and use
+       the new FW without having to reboot)
+     - Changed proc output
+==== ==========================================================================
+
+TODO
+====
+- Add 64 bit Scatter Gather when compiled on 64 bit architectures
+- Add sparse lun scanning
+- Add code that checks if a device that had been taken offline is
+  now online (at the FW level) when test unit ready or inquiry
+  command from scsi-core
+- Add proc read interface
+- busrescan command
+- rescan command
+- Add code to rescan routine that notifies scsi-core about new devices
+- Add support for C-PCI (hotplug stuff)
+- Add ioctl passthru error recovery
+
+Notes
+=====
+The DPT card optimizes the order of processing commands.  Consequently,
+a command may take up to 6 minutes to complete after it has been sent
+to the board.
+
+The files dpti_ioctl.h dptsig.h osd_defs.h osd_util.h sys_info.h are part of the
+interface files for Adaptec's management routines.  These define the structures used
+in the ioctls.  They are written to be portable.  They are hard to read, but I need

+
+This file documents the NCR53c400 extensions by Kevin Lentin and some
+enhancements to the NCR5380 core.
+
+This driver supports NCR5380 and NCR53c400 and compatible cards in port or
+memory mapped modes.
+
+Use of an interrupt is recommended, if supported by the board, as this will
+allow targets to disconnect and thereby improve SCSI bus utilization.
+
+If the irq parameter is 254 or is omitted entirely, the driver will probe
+for the correct IRQ line automatically. If the irq parameter is 0 or 255
+then no IRQ will be used.
+
+The NCR53c400 does not support DMA but it does have Pseudo-DMA which is
+supported by the driver.
+
+This driver provides some information on what it has detected in
+/proc/scsi/g_NCR5380/x where x is the scsi card number as detected at boot
+time. More info to come in the future.
+
+This driver works as a module.
+When included as a module, parameters can be passed on the insmod/modprobe
+command line:
+
+  ============= ===============================================================
+  irq=xx[,...]	the interrupt(s)
+  base=xx[,...]	the port or base address(es) (for port or memory mapped, resp.)

+SCSI mid_level - lower_level driver interface
+=============================================
+
+Introduction
+============
+This document outlines the interface between the Linux SCSI mid level and
+SCSI lower level drivers. Lower level drivers (LLDs) are variously called
+host bus adapter (HBA) drivers and host drivers (HD). A "host" in this
+context is a bridge between a computer IO bus (e.g. PCI or ISA) and a
+single SCSI initiator port on a SCSI transport. An "initiator" port
+(SCSI terminology, see SAM-3 at http://www.t10.org) sends SCSI commands
+to "target" SCSI ports (e.g. disks). There can be many LLDs in a running
+system, but only one per hardware type. Most LLDs can control one or more
+SCSI HBAs. Some HBAs contain multiple hosts.
+
+In some cases the SCSI transport is an external bus that already has
+its own subsystem in Linux (e.g. USB and ieee1394). In such cases the
+SCSI subsystem LLD is a software bridge to the other driver subsystem.
+Examples are the usb-storage driver (found in the drivers/usb/storage
+directory) and the ieee1394/sbp2 driver (found in the drivers/ieee1394
+directory).
+
+For example, the aic7xxx LLD controls Adaptec SCSI parallel interface
+(SPI) controllers based on that company's 7xxx chip series. The aic7xxx
+LLD can be built into the kernel or loaded as a module. There can only be
+one aic7xxx LLD running in a Linux system but it may be controlling many
+HBAs. These HBAs might be either on PCI daughter-boards or built into
+the motherboard (or both). Some aic7xxx based HBAs are dual controllers
+and thus represent two hosts. Like most modern HBAs, each aic7xxx host
+has its own PCI device address. [The one-to-one correspondence between
+a SCSI host and a PCI device is common but not required (e.g. with
+ISA adapters).]
+
+The SCSI mid level isolates an LLD from other layers such as the SCSI
+upper layer drivers and the block layer.
+
+This version of the document roughly matches linux kernel version 2.6.8 .
+
+Documentation
+=============
+There is a SCSI documentation directory within the kernel source tree,
+typically Documentation/scsi . Most documents are in plain
+(i.e. ASCII) text. This file is named scsi_mid_low_api.txt and can be
+found in that directory. A more recent copy of this document may be found
+at http://web.archive.org/web/20070107183357rn_1/sg.torque.net/scsi/.
+Many LLDs are documented there (e.g. aic7xxx.txt). The SCSI mid-level is
+briefly described in scsi.txt which contains a url to a document
+describing the SCSI subsystem in the lk 2.4 series. Two upper level
+drivers have documents in that directory: st.txt (SCSI tape driver) and
+scsi-generic.txt (for the sg driver).
+
+Some documentation (or urls) for LLDs may be found in the C source code
+or in the same directory as the C source code. For example to find a url
+about the USB mass storage driver see the
+/usr/src/linux/drivers/usb/storage directory.
+
+Driver structure
+================
+Traditionally an LLD for the SCSI subsystem has been at least two files in
+the drivers/scsi directory. For example, a driver called "xyz" has a header
+file "xyz.h" and a source file "xyz.c". [Actually there is no good reason
+why this couldn't all be in one file; the header file is superfluous.] Some
+drivers that have been ported to several operating systems have more than
+two files. For example the aic7xxx driver has separate files for generic
+and OS-specific code (e.g. FreeBSD and Linux). Such drivers tend to have
+their own directory under the drivers/scsi directory.
+
+When a new LLD is being added to Linux, the following files (found in the
+drivers/scsi directory) will need some attention: Makefile and Kconfig .
+It is probably best to study how existing LLDs are organized.
+
+As the 2.5 series development kernels evolve into the 2.6 series
+production series, changes are being introduced into this interface. An
+example of this is driver initialization code where there are now 2 models
+available. The older one, similar to what was found in the lk 2.4 series,
+is based on hosts that are detected at HBA driver load time. This will be
+referred to the "passive" initialization model. The newer model allows HBAs
+to be hot plugged (and unplugged) during the lifetime of the LLD and will
+be referred to as the "hotplug" initialization model. The newer model is
+preferred as it can handle both traditional SCSI equipment that is
+permanently connected as well as modern "SCSI" devices (e.g. USB or
+IEEE 1394 connected digital cameras) that are hotplugged. Both
+initialization models are discussed in the following sections.
+
+An LLD interfaces to the SCSI subsystem several ways:
+
+  a) directly invoking functions supplied by the mid level
+  b) passing a set of function pointers to a registration function
+     supplied by the mid level. The mid level will then invoke these
+     functions at some point in the future. The LLD will supply
+     implementations of these functions.
+  c) direct access to instances of well known data structures maintained
+     by the mid level
+
+Those functions in group a) are listed in a section entitled "Mid level
+supplied functions" below.
+
+Those functions in group b) are listed in a section entitled "Interface
+functions" below. Their function pointers are placed in the members of
+"struct scsi_host_template", an instance of which is passed to
+scsi_host_alloc() [#]_.  Those interface functions that the LLD does not
+wish to supply should have NULL placed in the corresponding member of
+struct scsi_host_template.  Defining an instance of struct
+scsi_host_template at file scope will cause NULL to be  placed in function
+pointer members not explicitly initialized.
+
+Those usages in group c) should be handled with care, especially in a
+"hotplug" environment. LLDs should be aware of the lifetime of instances
+that are shared with the mid level and other layers.
+
+All functions defined within an LLD and all data defined at file scope
+should be static. For example the slave_alloc() function in an LLD
+called "xxx" could be defined as
+``static int xxx_slave_alloc(struct scsi_device * sdev) { /* code */ }``
+
+.. [#] the scsi_host_alloc() function is a replacement for the rather vaguely
+       named scsi_register() function in most situations.
+
+
+Hotplug initialization model
+============================
+In this model an LLD controls when SCSI hosts are introduced and removed
+from the SCSI subsystem. Hosts can be introduced as early as driver
+initialization and removed as late as driver shutdown. Typically a driver
+will respond to a sysfs probe() callback that indicates an HBA has been
+detected. After confirming that the new device is one that the LLD wants
+to control, the LLD will initialize the HBA and then register a new host
+with the SCSI mid level.
+
+During LLD initialization the driver should register itself with the
+appropriate IO bus on which it expects to find HBA(s) (e.g. the PCI bus).
+This can probably be done via sysfs. Any driver parameters (especially
+those that are writable after the driver is loaded) could also be
+registered with sysfs at this point. The SCSI mid level first becomes
+aware of an LLD when that LLD registers its first HBA.
+
+At some later time, the LLD becomes aware of an HBA and what follows
+is a typical sequence of calls between the LLD and the mid level.
+This example shows the mid level scanning the newly introduced HBA for 3
+scsi devices of which only the first 2 respond::
+
+	HBA PROBE: assume 2 SCSI devices found in scan
+    LLD                   mid level                    LLD

+
+
+    *** For scsi devices that the mid level tries to scan but do not
+	respond, a slave_alloc(), slave_destroy() pair is called.
+
+If the LLD wants to adjust the default queue settings, it can invoke
+scsi_change_queue_depth() in its slave_configure() routine.

+associated with the LLD module being unloaded (e.g. with the "rmmod"
+command) or in response to a "hot unplug" indicated by sysfs()'s
+remove() callback being invoked. In either case, the sequence is the
+same::
+
+	    HBA REMOVE: assume 2 SCSI devices attached
+    LLD                      mid level                 LLD
+    ===----------------------=========-----------------===------
+    scsi_remove_host() ---------+
+				|
+			slave_destroy()
+			slave_destroy()
+    scsi_host_put()
+
+It may be useful for a LLD to keep track of struct Scsi_Host instances
+(a pointer is returned by scsi_host_alloc()). Such instances are "owned"
+by the mid-level.  struct Scsi_Host instances are freed from
+scsi_host_put() when the reference count hits zero.
+
+Hot unplugging an HBA that controls a disk which is processing SCSI
+commands on a mounted file system is an interesting situation. Reference
+counting logic is being introduced into the mid level to cope with many
+of the issues involved. See the section on reference counting below.
+
+
+The hotplug concept may be extended to SCSI devices. Currently, when an
+HBA is added, the scsi_scan_host() function causes a scan for SCSI devices
+attached to the HBA's SCSI transport. On newer SCSI transports the HBA
+may become aware of a new SCSI device _after_ the scan has completed.
+An LLD can use this sequence to make the mid level aware of a SCSI device::
+
+		    SCSI DEVICE hotplug
+    LLD                   mid level                    LLD
+    ===-------------------=========--------------------===------
+    scsi_add_device()  ------+
+			    |
+			slave_alloc()
+			slave_configure()   [--> scsi_change_queue_depth()]
+
+In a similar fashion, an LLD may become aware that a SCSI device has been
+removed (unplugged) or the connection to it has been interrupted. Some
+existing SCSI transports (e.g. SPI) may not become aware that a SCSI
+device has been removed until a subsequent SCSI command fails which will
+probably cause that device to be set offline by the mid level. An LLD that
+detects the removal of a SCSI device can instigate its removal from
+upper layers with this sequence::
+
+		    SCSI DEVICE hot unplug
+    LLD                      mid level                 LLD
+    ===----------------------=========-----------------===------
+    scsi_remove_device() -------+
+				|
+			slave_destroy()
+
+It may be useful for an LLD to keep track of struct scsi_device instances
+(a pointer is passed as the parameter to slave_alloc() and
+slave_configure() callbacks). Such instances are "owned" by the mid-level.
+struct scsi_device instances are freed after slave_destroy().
+
+
+Reference Counting
+==================
+The Scsi_Host structure has had reference counting infrastructure added.
+This effectively spreads the ownership of struct Scsi_Host instances
+across the various SCSI layers which use them. Previously such instances
+were exclusively owned by the mid level. LLDs would not usually need to
+directly manipulate these reference counts but there may be some cases
+where they do.
+
+There are 3 reference counting functions of interest associated with
+struct Scsi_Host:
+
+  - scsi_host_alloc():
+	returns a pointer to new instance of struct
+        Scsi_Host which has its reference count ^^ set to 1
+
+  - scsi_host_get():
+	adds 1 to the reference count of the given instance
+
+  - scsi_host_put():
+	decrements 1 from the reference count of the given
+        instance. If the reference count reaches 0 then the given instance
+        is freed
+
+The scsi_device structure has had reference counting infrastructure added.
+This effectively spreads the ownership of struct scsi_device instances
+across the various SCSI layers which use them. Previously such instances
+were exclusively owned by the mid level. See the access functions declared
+towards the end of include/scsi/scsi_device.h . If an LLD wants to keep
+a copy of a pointer to a scsi_device instance it should use scsi_device_get()
+to bump its reference count. When it is finished with the pointer it can
+use scsi_device_put() to decrement its reference count (and potentially
+delete it).
+
+.. Note::
+
+   struct Scsi_Host actually has 2 reference counts which are manipulated
+   in parallel by these functions.
+
+
+Conventions
+===========
+First, Linus Torvalds's thoughts on C coding style can be found in the
+Documentation/process/coding-style.rst file.
+
+Next, there is a movement to "outlaw" typedefs introducing synonyms for
+struct tags. Both can be still found in the SCSI subsystem, but
+the typedefs have been moved to a single file, scsi_typedefs.h to
+make their future removal easier, for example:
+"typedef struct scsi_cmnd Scsi_Cmnd;"
+
+Also, most C99 enhancements are encouraged to the extent they are supported
+by the relevant gcc compilers. So C99 style structure and array
+initializers are encouraged where appropriate. Don't go too far,
+VLAs are not properly supported yet.  An exception to this is the use of
+``//`` style comments; ``/*...*/`` comments are still preferred in Linux.
+
+Well written, tested and documented code, need not be re-formatted to
+comply with the above conventions. For example, the aic7xxx driver
+comes to Linux from FreeBSD and Adaptec's own labs. No doubt FreeBSD
+and Adaptec have their own coding conventions.
+
+
+Mid level supplied functions
+============================
+These functions are supplied by the SCSI mid level for use by LLDs.
+The names (i.e. entry points) of these functions are exported
+so an LLD that is a module can access them. The kernel will
+arrange for the SCSI mid level to be loaded and initialized before any LLD
+is initialized. The functions below are listed alphabetically and their
+names all start with ``scsi_``.
+
+Summary:
+
+  - scsi_add_device - creates new scsi device (lu) instance
+  - scsi_add_host - perform sysfs registration and set up transport class
+  - scsi_change_queue_depth - change the queue depth on a SCSI device
+  - scsi_bios_ptable - return copy of block device's partition table
+  - scsi_block_requests - prevent further commands being queued to given host
+  - scsi_host_alloc - return a new scsi_host instance whose refcount==1
+  - scsi_host_get - increments Scsi_Host instance's refcount
+  - scsi_host_put - decrements Scsi_Host instance's refcount (free if 0)
+  - scsi_register - create and register a scsi host adapter instance.
+  - scsi_remove_device - detach and remove a SCSI device
+  - scsi_remove_host - detach and remove all SCSI devices owned by host
+  - scsi_report_bus_reset - report scsi _bus_ reset observed
+  - scsi_scan_host - scan SCSI bus
+  - scsi_track_queue_full - track successive QUEUE_FULL events
+  - scsi_unblock_requests - allow further commands to be queued to given host
+  - scsi_unregister - [calls scsi_host_put()]

+Interface Functions
+===================
+Interface functions are supplied (defined) by LLDs and their function
+pointers are placed in an instance of struct scsi_host_template which
+is passed to scsi_host_alloc() [or scsi_register() / init_this_scsi_driver()].
+Some are mandatory. Interface functions should be declared static. The
+accepted convention is that driver "xyz" will declare its slave_configure()
+function as::
+
+    static int xyz_slave_configure(struct scsi_device * sdev);
+
+and so forth for all interface functions listed below.
+
+A pointer to this function should be placed in the 'slave_configure' member
+of a "struct scsi_host_template" instance. A pointer to such an instance
+should be passed to the mid level's scsi_host_alloc() [or scsi_register() /
+init_this_scsi_driver()].
+
+The interface functions are also described in the include/scsi/scsi_host.h
+file immediately above their definition point in "struct scsi_host_template".
+In some cases more detail is given in scsi_host.h than below.
+
+The interface functions are listed below in alphabetical order.
+
+Summary:
+
+  - bios_param - fetch head, sector, cylinder info for a disk
+  - eh_timed_out - notify the host that a command timer expired
+  - eh_abort_handler - abort given command
+  - eh_bus_reset_handler - issue SCSI bus reset
+  - eh_device_reset_handler - issue SCSI device reset
+  - eh_host_reset_handler - reset host (host bus adapter)
+  - info - supply information about given host
+  - ioctl - driver can respond to ioctls
+  - proc_info - supports /proc/scsi/{driver_name}/{host_no}
+  - queuecommand - queue scsi command, invoke 'done' on completion
+  - slave_alloc - prior to any commands being sent to a new device
+  - slave_configure - driver fine tuning for given device after attach
+  - slave_destroy - given device is about to be shut down

+Data Structures
+===============
+struct scsi_host_template
+-------------------------
+There is one "struct scsi_host_template" instance per LLD [#]_. It is
+typically initialized as a file scope static in a driver's header file. That
+way members that are not explicitly initialized will be set to 0 or NULL.
+Member of interest:
+
+    name
+		 - name of driver (may contain spaces, please limit to
+                   less than 80 characters)
+
+    proc_name
+		 - name used in "/proc/scsi/<proc_name>/<host_no>" and
+                   by sysfs in one of its "drivers" directories. Hence
+                   "proc_name" should only contain characters acceptable
+                   to a Unix file name.
+
+   ``(*queuecommand)()``
+		 - primary callback that the mid level uses to inject
+                   SCSI commands into an LLD.
+
+The structure is defined and commented in include/scsi/scsi_host.h
+
+.. [#] In extreme situations a single driver may have several instances
+       if it controls several different classes of hardware (e.g. an LLD
+       that handles both ISA and PCI cards and has a separate instance of
+       struct scsi_host_template for each class).
+
+struct Scsi_Host
+----------------
+There is one struct Scsi_Host instance per host (HBA) that an LLD
+controls. The struct Scsi_Host structure has many members in common
+with "struct scsi_host_template". When a new struct Scsi_Host instance
+is created (in scsi_host_alloc() in hosts.c) those common members are
+initialized from the driver's struct scsi_host_template instance. Members
+of interest:
+
+    host_no
+		 - system wide unique number that is used for identifying
+                   this host. Issued in ascending order from 0.
+    can_queue
+		 - must be greater than 0; do not send more than can_queue
+                   commands to the adapter.
+    this_id
+		 - scsi id of host (scsi initiator) or -1 if not known
+    sg_tablesize
+		 - maximum scatter gather elements allowed by host.
+                   Set this to SG_ALL or less to avoid chained SG lists.
+                   Must be at least 1.
+    max_sectors
+		 - maximum number of sectors (usually 512 bytes) allowed
+                   in a single SCSI command. The default value of 0 leads
+                   to a setting of SCSI_DEFAULT_MAX_SECTORS (defined in
+                   scsi_host.h) which is currently set to 1024. So for a
+                   disk the maximum transfer size is 512 KB when max_sectors
+                   is not defined. Note that this size may not be sufficient
+                   for disk firmware uploads.
+    cmd_per_lun
+		 - maximum number of commands that can be queued on devices
+                   controlled by the host. Overridden by LLD calls to
+                   scsi_change_queue_depth().
+    unchecked_isa_dma
+		 - 1=>only use bottom 16 MB of ram (ISA DMA addressing
+                   restriction), 0=>can use full 32 bit (or better) DMA
+                   address space
+    no_async_abort
+		 - 1=>Asynchronous aborts are not supported
+		 - 0=>Timed-out commands will be aborted asynchronously
+    hostt
+		 - pointer to driver's struct scsi_host_template from which
+                   this struct Scsi_Host instance was spawned
+    hostt->proc_name
+		 - name of LLD. This is the driver name that sysfs uses
+    transportt
+		 - pointer to driver's struct scsi_transport_template instance
+                   (if any). FC and SPI transports currently supported.
+    sh_list
+		 - a double linked list of pointers to all struct Scsi_Host
+                   instances (currently ordered by ascending host_no)
+    my_devices
+		 - a double linked list of pointers to struct scsi_device
+                   instances that belong to this host.
+    hostdata[0]
+		 - area reserved for LLD at end of struct Scsi_Host. Size
+                   is set by the second argument (named 'xtr_bytes') to
+                   scsi_host_alloc() or scsi_register().
+    vendor_id
+		 - a unique value that identifies the vendor supplying
+                   the LLD for the Scsi_Host.  Used most often in validating
+                   vendor-specific message requests.  Value consists of an
+                   identifier type and a vendor-specific value.
+                   See scsi_netlink.h for a description of valid formats.
+
+The scsi_host structure is defined in include/scsi/scsi_host.h
+
+struct scsi_device
+------------------
+Generally, there is one instance of this structure for each SCSI logical unit
+on a host. Scsi devices connected to a host are uniquely identified by a
+channel number, target id and logical unit number (lun).
+The structure is defined in include/scsi/scsi_device.h
+
+struct scsi_cmnd
+----------------
+Instances of this structure convey SCSI commands to the LLD and responses
+back to the mid level. The SCSI mid level will ensure that no more SCSI
+commands become queued against the LLD than are indicated by
+scsi_change_queue_depth() (or struct Scsi_Host::cmd_per_lun). There will
+be at least one instance of struct scsi_cmnd available for each SCSI device.
+Members of interest:
+
+    cmnd
+		 - array containing SCSI command
+    cmnd_len
+		 - length (in bytes) of SCSI command
+    sc_data_direction
+		 - direction of data transfer in data phase. See
+                   "enum dma_data_direction" in include/linux/dma-mapping.h
+    request_bufflen
+		 - number of data bytes to transfer (0 if no data phase)
+    use_sg
+		 - ==0 -> no scatter gather list, hence transfer data
+                          to/from request_buffer
+                 - >0 ->  scatter gather list (actually an array) in
+                          request_buffer with use_sg elements
+    request_buffer
+		   - either contains data buffer or scatter gather list
+                     depending on the setting of use_sg. Scatter gather
+                     elements are defined by 'struct scatterlist' found
+                     in include/linux/scatterlist.h .
+    done
+		 - function pointer that should be invoked by LLD when the
+                   SCSI command is completed (successfully or otherwise).
+                   Should only be called by an LLD if the LLD has accepted
+                   the command (i.e. queuecommand() returned or will return
+                   0). The LLD may invoke 'done'  prior to queuecommand()
+                   finishing.
+    result
+		 - should be set by LLD prior to calling 'done'. A value
+                   of 0 implies a successfully completed command (and all
+                   data (if any) has been transferred to or from the SCSI
+                   target device). 'result' is a 32 bit unsigned integer that
+                   can be viewed as 4 related bytes. The SCSI status value is
+                   in the LSB. See include/scsi/scsi.h status_byte(),
+                   msg_byte(), host_byte() and driver_byte() macros and
+                   related constants.
+    sense_buffer
+		 - an array (maximum size: SCSI_SENSE_BUFFERSIZE bytes) that
+                   should be written when the SCSI status (LSB of 'result')
+                   is set to CHECK_CONDITION (2). When CHECK_CONDITION is
+                   set, if the top nibble of sense_buffer[0] has the value 7
+                   then the mid level will assume the sense_buffer array
+                   contains a valid SCSI sense buffer; otherwise the mid
+                   level will issue a REQUEST_SENSE SCSI command to
+                   retrieve the sense buffer. The latter strategy is error
+                   prone in the presence of command queuing so the LLD should
+                   always "auto-sense".
+    device
+		 - pointer to scsi_device object that this command is
+                   associated with.
+    resid
+		 - an LLD should set this signed integer to the requested
+                   transfer length (i.e. 'request_bufflen') less the number
+                   of bytes that are actually transferred. 'resid' is
+                   preset to 0 so an LLD can ignore it if it cannot detect
+                   underruns (overruns should be rare). If possible an LLD
+                   should set 'resid' prior to invoking 'done'. The most
+                   interesting case is data transfers from a SCSI target
+                   device (e.g. READs) that underrun.
+    underflow
+		 - LLD should place (DID_ERROR << 16) in 'result' if
+                   actual number of bytes transferred is less than this
+                   figure. Not many LLDs implement this check and some that
+                   do just output an error message to the log rather than
+                   report a DID_ERROR. Better for an LLD to implement
+                   'resid'.
+
+It is recommended that a LLD set 'resid' on data transfers from a SCSI
+target device (e.g. READs). It is especially important that 'resid' is set
+when such data transfers have sense keys of MEDIUM ERROR and HARDWARE ERROR
+(and possibly RECOVERED ERROR). In these cases if a LLD is in doubt how much
+data has been received then the safest approach is to indicate no bytes have
+been received. For example: to indicate that no valid data has been received
+a LLD might use these helpers::
+
+    scsi_set_resid(SCpnt, scsi_bufflen(SCpnt));
+
+where 'SCpnt' is a pointer to a scsi_cmnd object. To indicate only three 512
+bytes blocks has been received 'resid' could be set like this::
+
+    scsi_set_resid(SCpnt, scsi_bufflen(SCpnt) - (3 * 512));
+
+The scsi_cmnd structure is defined in include/scsi/scsi_cmnd.h
+
+
+Locks
+=====
+Each struct Scsi_Host instance has a spin_lock called struct
+Scsi_Host::default_lock which is initialized in scsi_host_alloc() [found in
+hosts.c]. Within the same function the struct Scsi_Host::host_lock pointer
+is initialized to point at default_lock.  Thereafter lock and unlock
+operations performed by the mid level use the struct Scsi_Host::host_lock
+pointer.  Previously drivers could override the host_lock pointer but
+this is not allowed anymore.
+
+
+Autosense
+=========
+Autosense (or auto-sense) is defined in the SAM-2 document as "the
+automatic return of sense data to the application client coincident
+with the completion of a SCSI command" when a status of CHECK CONDITION
+occurs. LLDs should perform autosense. This should be done when the LLD
+detects a CHECK CONDITION status by either:
+
+    a) instructing the SCSI protocol (e.g. SCSI Parallel Interface (SPI))
+       to perform an extra data in phase on such responses
+    b) or, the LLD issuing a REQUEST SENSE command itself
+
+Either way, when a status of CHECK CONDITION is detected, the mid level
+decides whether the LLD has performed autosense by checking struct
+scsi_cmnd::sense_buffer[0] . If this byte has an upper nibble of 7 (or 0xf)
+then autosense is assumed to have taken place. If it has another value (and
+this byte is initialized to 0 before each command) then the mid level will
+issue a REQUEST SENSE command.
+
+In the presence of queued commands the "nexus" that maintains sense
+buffer data from the command that failed until a following REQUEST SENSE
+may get out of synchronization. This is why it is best for the LLD
+to perform autosense.
+
+
+Changes since lk 2.4 series
+===========================
+io_request_lock has been replaced by several finer grained locks. The lock
+relevant to LLDs is struct Scsi_Host::host_lock and there is
+one per SCSI host.
+
+The older error handling mechanism has been removed. This means the
+LLD interface functions abort() and reset() have been removed.
+The struct scsi_host_template::use_new_eh_code flag has been removed.
+
+In the 2.4 series the SCSI subsystem configuration descriptions were
+aggregated with the configuration descriptions from all other Linux
+subsystems in the Documentation/Configure.help file. In the 2.6 series,
+the SCSI subsystem now has its own (much smaller) drivers/scsi/Kconfig
+file that contains both configuration and help information.
+
+struct SHT has been renamed to struct scsi_host_template.
+
+Addition of the "hotplug initialization model" and many extra functions
+to support it.

-                          Linux Kernel 2.6 series
-                 SCSI mid_level - lower_level driver interface
-                 =============================================
-
-Introduction
-============
-This document outlines the interface between the Linux SCSI mid level and
-SCSI lower level drivers. Lower level drivers (LLDs) are variously called 
-host bus adapter (HBA) drivers and host drivers (HD). A "host" in this
-context is a bridge between a computer IO bus (e.g. PCI or ISA) and a
-single SCSI initiator port on a SCSI transport. An "initiator" port
-(SCSI terminology, see SAM-3 at http://www.t10.org) sends SCSI commands
-to "target" SCSI ports (e.g. disks). There can be many LLDs in a running
-system, but only one per hardware type. Most LLDs can control one or more
-SCSI HBAs. Some HBAs contain multiple hosts.
-
-In some cases the SCSI transport is an external bus that already has
-its own subsystem in Linux (e.g. USB and ieee1394). In such cases the
-SCSI subsystem LLD is a software bridge to the other driver subsystem.
-Examples are the usb-storage driver (found in the drivers/usb/storage
-directory) and the ieee1394/sbp2 driver (found in the drivers/ieee1394
-directory).
-
-For example, the aic7xxx LLD controls Adaptec SCSI parallel interface
-(SPI) controllers based on that company's 7xxx chip series. The aic7xxx
-LLD can be built into the kernel or loaded as a module. There can only be
-one aic7xxx LLD running in a Linux system but it may be controlling many 
-HBAs. These HBAs might be either on PCI daughter-boards or built into 
-the motherboard (or both). Some aic7xxx based HBAs are dual controllers
-and thus represent two hosts. Like most modern HBAs, each aic7xxx host
-has its own PCI device address. [The one-to-one correspondence between
-a SCSI host and a PCI device is common but not required (e.g. with
-ISA adapters).]
-
-The SCSI mid level isolates an LLD from other layers such as the SCSI
-upper layer drivers and the block layer.
-
-This version of the document roughly matches linux kernel version 2.6.8 .
-
-Documentation
-=============
-There is a SCSI documentation directory within the kernel source tree, 
-typically Documentation/scsi . Most documents are in plain
-(i.e. ASCII) text. This file is named scsi_mid_low_api.txt and can be 
-found in that directory. A more recent copy of this document may be found
-at http://web.archive.org/web/20070107183357rn_1/sg.torque.net/scsi/. 
-Many LLDs are documented there (e.g. aic7xxx.txt). The SCSI mid-level is
-briefly described in scsi.txt which contains a url to a document 
-describing the SCSI subsystem in the lk 2.4 series. Two upper level 
-drivers have documents in that directory: st.txt (SCSI tape driver) and 
-scsi-generic.txt (for the sg driver).
-
-Some documentation (or urls) for LLDs may be found in the C source code
-or in the same directory as the C source code. For example to find a url
-about the USB mass storage driver see the 
-/usr/src/linux/drivers/usb/storage directory.
-
-Driver structure
-================
-Traditionally an LLD for the SCSI subsystem has been at least two files in
-the drivers/scsi directory. For example, a driver called "xyz" has a header
-file "xyz.h" and a source file "xyz.c". [Actually there is no good reason
-why this couldn't all be in one file; the header file is superfluous.] Some
-drivers that have been ported to several operating systems have more than
-two files. For example the aic7xxx driver has separate files for generic 
-and OS-specific code (e.g. FreeBSD and Linux). Such drivers tend to have
-their own directory under the drivers/scsi directory.
-
-When a new LLD is being added to Linux, the following files (found in the
-drivers/scsi directory) will need some attention: Makefile and Kconfig .
-It is probably best to study how existing LLDs are organized.
-
-As the 2.5 series development kernels evolve into the 2.6 series
-production series, changes are being introduced into this interface. An
-example of this is driver initialization code where there are now 2 models
-available. The older one, similar to what was found in the lk 2.4 series,
-is based on hosts that are detected at HBA driver load time. This will be
-referred to the "passive" initialization model. The newer model allows HBAs
-to be hot plugged (and unplugged) during the lifetime of the LLD and will
-be referred to as the "hotplug" initialization model. The newer model is
-preferred as it can handle both traditional SCSI equipment that is
-permanently connected as well as modern "SCSI" devices (e.g. USB or
-IEEE 1394 connected digital cameras) that are hotplugged. Both 
-initialization models are discussed in the following sections.
-
-An LLD interfaces to the SCSI subsystem several ways:
-  a) directly invoking functions supplied by the mid level
-  b) passing a set of function pointers to a registration function
-     supplied by the mid level. The mid level will then invoke these
-     functions at some point in the future. The LLD will supply
-     implementations of these functions.
-  c) direct access to instances of well known data structures maintained
-     by the mid level
-
-Those functions in group a) are listed in a section entitled "Mid level
-supplied functions" below.
-
-Those functions in group b) are listed in a section entitled "Interface
-functions" below. Their function pointers are placed in the members of
-"struct scsi_host_template", an instance of which is passed to
-scsi_host_alloc() ** .  Those interface functions that the LLD does not 
-wish to supply should have NULL placed in the corresponding member of 
-struct scsi_host_template.  Defining an instance of struct 
-scsi_host_template at file scope will cause NULL to be  placed in function
- pointer members not explicitly initialized.
-
-Those usages in group c) should be handled with care, especially in a
-"hotplug" environment. LLDs should be aware of the lifetime of instances
-that are shared with the mid level and other layers.
-
-All functions defined within an LLD and all data defined at file scope
-should be static. For example the slave_alloc() function in an LLD
-called "xxx" could be defined as 
-"static int xxx_slave_alloc(struct scsi_device * sdev) { /* code */ }"
-
-** the scsi_host_alloc() function is a replacement for the rather vaguely
-named scsi_register() function in most situations.
-
-
-Hotplug initialization model
-============================
-In this model an LLD controls when SCSI hosts are introduced and removed
-from the SCSI subsystem. Hosts can be introduced as early as driver
-initialization and removed as late as driver shutdown. Typically a driver
-will respond to a sysfs probe() callback that indicates an HBA has been
-detected. After confirming that the new device is one that the LLD wants
-to control, the LLD will initialize the HBA and then register a new host
-with the SCSI mid level.
-
-During LLD initialization the driver should register itself with the
-appropriate IO bus on which it expects to find HBA(s) (e.g. the PCI bus).
-This can probably be done via sysfs. Any driver parameters (especially
-those that are writable after the driver is loaded) could also be
-registered with sysfs at this point. The SCSI mid level first becomes
-aware of an LLD when that LLD registers its first HBA.
-
-At some later time, the LLD becomes aware of an HBA and what follows
-is a typical sequence of calls between the LLD and the mid level.
-This example shows the mid level scanning the newly introduced HBA for 3 
-scsi devices of which only the first 2 respond:
-
-     HBA PROBE: assume 2 SCSI devices found in scan
-LLD                   mid level                    LLD
-===-------------------=========--------------------===------
-scsi_host_alloc()  -->
-scsi_add_host()  ---->
-scsi_scan_host()  -------+
-                         |
-                    slave_alloc()
-                    slave_configure() -->  scsi_change_queue_depth()
-                         |
-                    slave_alloc()
-                    slave_configure()
-                         |
-                    slave_alloc()   ***
-                    slave_destroy() ***
-------------------------------------------------------------
-
-If the LLD wants to adjust the default queue settings, it can invoke
-scsi_change_queue_depth() in its slave_configure() routine.
-
-*** For scsi devices that the mid level tries to scan but do not
-    respond, a slave_alloc(), slave_destroy() pair is called.
-
-When an HBA is being removed it could be as part of an orderly shutdown
-associated with the LLD module being unloaded (e.g. with the "rmmod"
-command) or in response to a "hot unplug" indicated by sysfs()'s
-remove() callback being invoked. In either case, the sequence is the
-same:
-
-        HBA REMOVE: assume 2 SCSI devices attached
-LLD                      mid level                 LLD
-===----------------------=========-----------------===------
-scsi_remove_host() ---------+
-                            |
-                     slave_destroy()
-                     slave_destroy()
-scsi_host_put()
-------------------------------------------------------------
-                     
-It may be useful for a LLD to keep track of struct Scsi_Host instances
-(a pointer is returned by scsi_host_alloc()). Such instances are "owned"
-by the mid-level.  struct Scsi_Host instances are freed from
-scsi_host_put() when the reference count hits zero.
-
-Hot unplugging an HBA that controls a disk which is processing SCSI
-commands on a mounted file system is an interesting situation. Reference
-counting logic is being introduced into the mid level to cope with many
-of the issues involved. See the section on reference counting below.
-
-
-The hotplug concept may be extended to SCSI devices. Currently, when an
-HBA is added, the scsi_scan_host() function causes a scan for SCSI devices
-attached to the HBA's SCSI transport. On newer SCSI transports the HBA
-may become aware of a new SCSI device _after_ the scan has completed.
-An LLD can use this sequence to make the mid level aware of a SCSI device:
-
-                 SCSI DEVICE hotplug
-LLD                   mid level                    LLD
-===-------------------=========--------------------===------
-scsi_add_device()  ------+
-                         |
-                    slave_alloc()
-                    slave_configure()   [--> scsi_change_queue_depth()]
-------------------------------------------------------------
-
-In a similar fashion, an LLD may become aware that a SCSI device has been
-removed (unplugged) or the connection to it has been interrupted. Some
-existing SCSI transports (e.g. SPI) may not become aware that a SCSI
-device has been removed until a subsequent SCSI command fails which will
-probably cause that device to be set offline by the mid level. An LLD that
-detects the removal of a SCSI device can instigate its removal from
-upper layers with this sequence:
-
-                  SCSI DEVICE hot unplug
-LLD                      mid level                 LLD
-===----------------------=========-----------------===------
-scsi_remove_device() -------+
-                            |
-                     slave_destroy()
-------------------------------------------------------------
-
-It may be useful for an LLD to keep track of struct scsi_device instances
-(a pointer is passed as the parameter to slave_alloc() and
-slave_configure() callbacks). Such instances are "owned" by the mid-level.
-struct scsi_device instances are freed after slave_destroy().
-
-
-Reference Counting
-==================
-The Scsi_Host structure has had reference counting infrastructure added.
-This effectively spreads the ownership of struct Scsi_Host instances
-across the various SCSI layers which use them. Previously such instances
-were exclusively owned by the mid level. LLDs would not usually need to
-directly manipulate these reference counts but there may be some cases
-where they do.
-
-There are 3 reference counting functions of interest associated with
-struct Scsi_Host:
-  - scsi_host_alloc(): returns a pointer to new instance of struct 
-        Scsi_Host which has its reference count ^^ set to 1
-  - scsi_host_get(): adds 1 to the reference count of the given instance
-  - scsi_host_put(): decrements 1 from the reference count of the given
-        instance. If the reference count reaches 0 then the given instance
-        is freed
-
-The scsi_device structure has had reference counting infrastructure added.
-This effectively spreads the ownership of struct scsi_device instances
-across the various SCSI layers which use them. Previously such instances
-were exclusively owned by the mid level. See the access functions declared
-towards the end of include/scsi/scsi_device.h . If an LLD wants to keep
-a copy of a pointer to a scsi_device instance it should use scsi_device_get()
-to bump its reference count. When it is finished with the pointer it can
-use scsi_device_put() to decrement its reference count (and potentially
-delete it).
-
-^^ struct Scsi_Host actually has 2 reference counts which are manipulated
-in parallel by these functions.
-
-
-Conventions
-===========
-First, Linus Torvalds's thoughts on C coding style can be found in the
-Documentation/process/coding-style.rst file.
-
-Next, there is a movement to "outlaw" typedefs introducing synonyms for 
-struct tags. Both can be still found in the SCSI subsystem, but
-the typedefs have been moved to a single file, scsi_typedefs.h to
-make their future removal easier, for example: 
-"typedef struct scsi_cmnd Scsi_Cmnd;"
-
-Also, most C99 enhancements are encouraged to the extent they are supported
-by the relevant gcc compilers. So C99 style structure and array
-initializers are encouraged where appropriate. Don't go too far,
-VLAs are not properly supported yet.  An exception to this is the use of
-"//" style comments; /*...*/ comments are still preferred in Linux.
-
-Well written, tested and documented code, need not be re-formatted to
-comply with the above conventions. For example, the aic7xxx driver
-comes to Linux from FreeBSD and Adaptec's own labs. No doubt FreeBSD
-and Adaptec have their own coding conventions.
-
-
-Mid level supplied functions
-============================
-These functions are supplied by the SCSI mid level for use by LLDs.
-The names (i.e. entry points) of these functions are exported 
-so an LLD that is a module can access them. The kernel will
-arrange for the SCSI mid level to be loaded and initialized before any LLD
-is initialized. The functions below are listed alphabetically and their
-names all start with "scsi_".
-
-Summary:
-   scsi_add_device - creates new scsi device (lu) instance
-   scsi_add_host - perform sysfs registration and set up transport class
-   scsi_change_queue_depth - change the queue depth on a SCSI device
-   scsi_bios_ptable - return copy of block device's partition table
-   scsi_block_requests - prevent further commands being queued to given host
-   scsi_host_alloc - return a new scsi_host instance whose refcount==1
-   scsi_host_get - increments Scsi_Host instance's refcount
-   scsi_host_put - decrements Scsi_Host instance's refcount (free if 0)
-   scsi_partsize - parse partition table into cylinders, heads + sectors
-   scsi_register - create and register a scsi host adapter instance.
-   scsi_remove_device - detach and remove a SCSI device
-   scsi_remove_host - detach and remove all SCSI devices owned by host
-   scsi_report_bus_reset - report scsi _bus_ reset observed
-   scsi_scan_host - scan SCSI bus
-   scsi_track_queue_full - track successive QUEUE_FULL events 
-   scsi_unblock_requests - allow further commands to be queued to given host
-   scsi_unregister - [calls scsi_host_put()]
-
-
-Details:
-
-/**
- * scsi_add_device - creates new scsi device (lu) instance
- * @shost:   pointer to scsi host instance
- * @channel: channel number (rarely other than 0)
- * @id:      target id number
- * @lun:     logical unit number
- *
- *      Returns pointer to new struct scsi_device instance or

- *      Notes: This call is usually performed internally during a scsi

-Interface Functions
-===================
-Interface functions are supplied (defined) by LLDs and their function
-pointers are placed in an instance of struct scsi_host_template which
-is passed to scsi_host_alloc() [or scsi_register() / init_this_scsi_driver()].
-Some are mandatory. Interface functions should be declared static. The
-accepted convention is that driver "xyz" will declare its slave_configure() 
-function as:
-    static int xyz_slave_configure(struct scsi_device * sdev);
-and so forth for all interface functions listed below.
-
-A pointer to this function should be placed in the 'slave_configure' member
-of a "struct scsi_host_template" instance. A pointer to such an instance
-should be passed to the mid level's scsi_host_alloc() [or scsi_register() /
-init_this_scsi_driver()].
-
-The interface functions are also described in the include/scsi/scsi_host.h
-file immediately above their definition point in "struct scsi_host_template".
-In some cases more detail is given in scsi_host.h than below.
-
-The interface functions are listed below in alphabetical order.
-
-Summary:
-   bios_param - fetch head, sector, cylinder info for a disk
-   eh_timed_out - notify the host that a command timer expired
-   eh_abort_handler - abort given command
-   eh_bus_reset_handler - issue SCSI bus reset
-   eh_device_reset_handler - issue SCSI device reset
-   eh_host_reset_handler - reset host (host bus adapter)
-   info - supply information about given host
-   ioctl - driver can respond to ioctls
-   proc_info - supports /proc/scsi/{driver_name}/{host_no}
-   queuecommand - queue scsi command, invoke 'done' on completion
-   slave_alloc - prior to any commands being sent to a new device 
-   slave_configure - driver fine tuning for given device after attach
-   slave_destroy - given device is about to be shut down
-

- *      On both of these returns, the mid-layer will requeue the I/O
- *
- *      - if the return is SCSI_MLQUEUE_DEVICE_BUSY, only that particular
- *      device will be paused, and it will be unpaused when a command to
- *      the device returns (or after a brief delay if there are no more
- *      outstanding commands to it).  Commands to other devices continue
- *      to be processed normally.
- *
- *      - if the return is SCSI_MLQUEUE_HOST_BUSY, all I/O to the host
- *      is paused and will be unpaused when any command returns from
- *      the host (or after a brief delay if there are no outstanding
- *      commands to the host).
- *
- *      For compatibility with earlier versions of queuecommand, any
- *      other return value is treated the same as
- *      SCSI_MLQUEUE_HOST_BUSY.
- *
- *      Other types of errors that are detected immediately may be
- *      flagged by setting scp->result to an appropriate value,
- *      invoking the scp->scsi_done callback, and then returning 0
- *      from this function. If the command is not performed
- *      immediately (and the LLD is starting (or will start) the given
- *      command) then this function should place 0 in scp->result and
- *      return 0.
- *
- *      Command ownership.  If the driver returns zero, it owns the
- *      command and must take responsibility for ensuring the
- *      scp->scsi_done callback is executed.  Note: the driver may
- *      call scp->scsi_done before returning zero, but after it has
- *      called scp->scsi_done, it may not return any value other than
- *      zero.  If the driver makes a non-zero return, it must not
- *      execute the command's scsi_done callback at any time.
- *
- *      Locks: up to and including 2.6.36, struct Scsi_Host::host_lock
- *             held on entry (with "irqsave") and is expected to be
- *             held on return. From 2.6.37 onwards, queuecommand is
- *             called without any locks held.
- *
- *      Calling context: in interrupt (soft irq) or process context
- *
- *      Notes: This function should be relatively fast. Normally it
- *      will not wait for IO to complete. Hence the scp->scsi_done
- *      callback is invoked (often directly from an interrupt service
- *      routine) some time after this function has returned. In some
- *      cases (e.g. pseudo adapter drivers that manufacture the
- *      response to a SCSI INQUIRY) the scp->scsi_done callback may be
- *      invoked before this function returns.  If the scp->scsi_done
- *      callback is not invoked within a certain period the SCSI mid
- *      level will commence error processing.  If a status of CHECK
- *      CONDITION is placed in "result" when the scp->scsi_done
- *      callback is invoked, then the LLD driver should perform
- *      autosense and fill in the struct scsi_cmnd::sense_buffer
- *      array. The scsi_cmnd::sense_buffer array is zeroed prior to

-Data Structures
-===============
-struct scsi_host_template
--------------------------
-There is one "struct scsi_host_template" instance per LLD ***. It is
-typically initialized as a file scope static in a driver's header file. That
-way members that are not explicitly initialized will be set to 0 or NULL.
-Member of interest:
-    name         - name of driver (may contain spaces, please limit to
-                   less than 80 characters)
-    proc_name    - name used in "/proc/scsi/<proc_name>/<host_no>" and
-                   by sysfs in one of its "drivers" directories. Hence
-                   "proc_name" should only contain characters acceptable
-                   to a Unix file name.
-   (*queuecommand)() - primary callback that the mid level uses to inject
-                   SCSI commands into an LLD.
-The structure is defined and commented in include/scsi/scsi_host.h
-
-*** In extreme situations a single driver may have several instances
-    if it controls several different classes of hardware (e.g. an LLD
-    that handles both ISA and PCI cards and has a separate instance of
-    struct scsi_host_template for each class).
-
-struct Scsi_Host
-----------------
-There is one struct Scsi_Host instance per host (HBA) that an LLD
-controls. The struct Scsi_Host structure has many members in common
-with "struct scsi_host_template". When a new struct Scsi_Host instance
-is created (in scsi_host_alloc() in hosts.c) those common members are
-initialized from the driver's struct scsi_host_template instance. Members
-of interest:
-    host_no      - system wide unique number that is used for identifying
-                   this host. Issued in ascending order from 0.
-    can_queue    - must be greater than 0; do not send more than can_queue
-                   commands to the adapter.
-    this_id      - scsi id of host (scsi initiator) or -1 if not known
-    sg_tablesize - maximum scatter gather elements allowed by host.
-                   Set this to SG_ALL or less to avoid chained SG lists.
-                   Must be at least 1.
-    max_sectors  - maximum number of sectors (usually 512 bytes) allowed
-                   in a single SCSI command. The default value of 0 leads
-                   to a setting of SCSI_DEFAULT_MAX_SECTORS (defined in
-                   scsi_host.h) which is currently set to 1024. So for a
-                   disk the maximum transfer size is 512 KB when max_sectors
-                   is not defined. Note that this size may not be sufficient
-                   for disk firmware uploads.
-    cmd_per_lun  - maximum number of commands that can be queued on devices
-                   controlled by the host. Overridden by LLD calls to
-                   scsi_change_queue_depth().
-    unchecked_isa_dma - 1=>only use bottom 16 MB of ram (ISA DMA addressing
-                   restriction), 0=>can use full 32 bit (or better) DMA
-                   address space
-    no_async_abort - 1=>Asynchronous aborts are not supported
-                     0=>Timed-out commands will be aborted asynchronously
-    hostt        - pointer to driver's struct scsi_host_template from which
-                   this struct Scsi_Host instance was spawned
-    hostt->proc_name  - name of LLD. This is the driver name that sysfs uses
-    transportt   - pointer to driver's struct scsi_transport_template instance
-                   (if any). FC and SPI transports currently supported.
-    sh_list      - a double linked list of pointers to all struct Scsi_Host
-                   instances (currently ordered by ascending host_no)
-    my_devices   - a double linked list of pointers to struct scsi_device 
-                   instances that belong to this host.
-    hostdata[0]  - area reserved for LLD at end of struct Scsi_Host. Size
-                   is set by the second argument (named 'xtr_bytes') to
-                   scsi_host_alloc() or scsi_register().
-    vendor_id    - a unique value that identifies the vendor supplying
-                   the LLD for the Scsi_Host.  Used most often in validating
-                   vendor-specific message requests.  Value consists of an
-                   identifier type and a vendor-specific value.
-                   See scsi_netlink.h for a description of valid formats.
-
-The scsi_host structure is defined in include/scsi/scsi_host.h
-
-struct scsi_device
-------------------
-Generally, there is one instance of this structure for each SCSI logical unit
-on a host. Scsi devices connected to a host are uniquely identified by a
-channel number, target id and logical unit number (lun).
-The structure is defined in include/scsi/scsi_device.h
-
-struct scsi_cmnd
-----------------
-Instances of this structure convey SCSI commands to the LLD and responses
-back to the mid level. The SCSI mid level will ensure that no more SCSI
-commands become queued against the LLD than are indicated by
-scsi_change_queue_depth() (or struct Scsi_Host::cmd_per_lun). There will
-be at least one instance of struct scsi_cmnd available for each SCSI device.
-Members of interest:
-    cmnd         - array containing SCSI command
-    cmnd_len     - length (in bytes) of SCSI command
-    sc_data_direction - direction of data transfer in data phase. See
-                "enum dma_data_direction" in include/linux/dma-mapping.h
-    request_bufflen - number of data bytes to transfer (0 if no data phase)
-    use_sg       - ==0 -> no scatter gather list, hence transfer data
-                          to/from request_buffer
-                 - >0 ->  scatter gather list (actually an array) in
-                          request_buffer with use_sg elements
-    request_buffer - either contains data buffer or scatter gather list
-                     depending on the setting of use_sg. Scatter gather
-                     elements are defined by 'struct scatterlist' found
-                     in include/linux/scatterlist.h .
-    done         - function pointer that should be invoked by LLD when the
-                   SCSI command is completed (successfully or otherwise).
-                   Should only be called by an LLD if the LLD has accepted
-                   the command (i.e. queuecommand() returned or will return
-                   0). The LLD may invoke 'done'  prior to queuecommand()
-                   finishing.
-    result       - should be set by LLD prior to calling 'done'. A value
-                   of 0 implies a successfully completed command (and all
-                   data (if any) has been transferred to or from the SCSI
-                   target device). 'result' is a 32 bit unsigned integer that
-                   can be viewed as 4 related bytes. The SCSI status value is
-                   in the LSB. See include/scsi/scsi.h status_byte(),
-                   msg_byte(), host_byte() and driver_byte() macros and
-                   related constants.
-    sense_buffer - an array (maximum size: SCSI_SENSE_BUFFERSIZE bytes) that
-                   should be written when the SCSI status (LSB of 'result')
-                   is set to CHECK_CONDITION (2). When CHECK_CONDITION is
-                   set, if the top nibble of sense_buffer[0] has the value 7
-                   then the mid level will assume the sense_buffer array
-                   contains a valid SCSI sense buffer; otherwise the mid
-                   level will issue a REQUEST_SENSE SCSI command to
-                   retrieve the sense buffer. The latter strategy is error
-                   prone in the presence of command queuing so the LLD should
-                   always "auto-sense".
-    device       - pointer to scsi_device object that this command is
-                   associated with.
-    resid        - an LLD should set this signed integer to the requested
-                   transfer length (i.e. 'request_bufflen') less the number
-                   of bytes that are actually transferred. 'resid' is
-                   preset to 0 so an LLD can ignore it if it cannot detect
-                   underruns (overruns should be rare). If possible an LLD
-                   should set 'resid' prior to invoking 'done'. The most
-                   interesting case is data transfers from a SCSI target
-                   device (e.g. READs) that underrun.
-    underflow    - LLD should place (DID_ERROR << 16) in 'result' if
-                   actual number of bytes transferred is less than this
-                   figure. Not many LLDs implement this check and some that
-                   do just output an error message to the log rather than
-                   report a DID_ERROR. Better for an LLD to implement
-                   'resid'.
-
-It is recommended that a LLD set 'resid' on data transfers from a SCSI
-target device (e.g. READs). It is especially important that 'resid' is set
-when such data transfers have sense keys of MEDIUM ERROR and HARDWARE ERROR
-(and possibly RECOVERED ERROR). In these cases if a LLD is in doubt how much
-data has been received then the safest approach is to indicate no bytes have
-been received. For example: to indicate that no valid data has been received
-a LLD might use these helpers:
-    scsi_set_resid(SCpnt, scsi_bufflen(SCpnt));
-where 'SCpnt' is a pointer to a scsi_cmnd object. To indicate only three 512
-bytes blocks has been received 'resid' could be set like this:
-    scsi_set_resid(SCpnt, scsi_bufflen(SCpnt) - (3 * 512));
-
-The scsi_cmnd structure is defined in include/scsi/scsi_cmnd.h
-
-
-Locks
-=====
-Each struct Scsi_Host instance has a spin_lock called struct 
-Scsi_Host::default_lock which is initialized in scsi_host_alloc() [found in 
-hosts.c]. Within the same function the struct Scsi_Host::host_lock pointer
-is initialized to point at default_lock.  Thereafter lock and unlock
-operations performed by the mid level use the struct Scsi_Host::host_lock
-pointer.  Previously drivers could override the host_lock pointer but
-this is not allowed anymore.
-
-
-Autosense
-=========
-Autosense (or auto-sense) is defined in the SAM-2 document as "the
-automatic return of sense data to the application client coincident
-with the completion of a SCSI command" when a status of CHECK CONDITION
-occurs. LLDs should perform autosense. This should be done when the LLD
-detects a CHECK CONDITION status by either: 
-    a) instructing the SCSI protocol (e.g. SCSI Parallel Interface (SPI))
-       to perform an extra data in phase on such responses
-    b) or, the LLD issuing a REQUEST SENSE command itself
-
-Either way, when a status of CHECK CONDITION is detected, the mid level
-decides whether the LLD has performed autosense by checking struct 
-scsi_cmnd::sense_buffer[0] . If this byte has an upper nibble of 7 (or 0xf)
-then autosense is assumed to have taken place. If it has another value (and
-this byte is initialized to 0 before each command) then the mid level will
-issue a REQUEST SENSE command.
-
-In the presence of queued commands the "nexus" that maintains sense
-buffer data from the command that failed until a following REQUEST SENSE
-may get out of synchronization. This is why it is best for the LLD
-to perform autosense.
-
-
-Changes since lk 2.4 series
-===========================
-io_request_lock has been replaced by several finer grained locks. The lock 
-relevant to LLDs is struct Scsi_Host::host_lock and there is
-one per SCSI host.
-
-The older error handling mechanism has been removed. This means the
-LLD interface functions abort() and reset() have been removed.
-The struct scsi_host_template::use_new_eh_code flag has been removed.
-
-In the 2.4 series the SCSI subsystem configuration descriptions were 
-aggregated with the configuration descriptions from all other Linux 
-subsystems in the Documentation/Configure.help file. In the 2.6 series, 
-the SCSI subsystem now has its own (much smaller) drivers/scsi/Kconfig
-file that contains both configuration and help information.
-
-struct SHT has been renamed to struct scsi_host_template.
-
-Addition of the "hotplug initialization model" and many extra functions
-to support it.

+Realtek PC Beep Hidden Register
+===============================
+
+This file documents the "PC Beep Hidden Register", which is present in certain
+Realtek HDA codecs and controls a muxer and pair of passthrough mixers that can
+route audio between pins but aren't themselves exposed as HDA widgets. As far
+as I can tell, these hidden routes are designed to allow flexible PC Beep output
+for codecs that don't have mixer widgets in their output paths. Why it's easier
+to hide a mixer behind an undocumented vendor register than to just expose it
+as a widget, I have no idea.
+
+Register Description

+
+Background
+==========
+
+All Realtek HDA codecs have a vendor-defined widget with node ID 20h which
+provides access to a bank of registers that control various codec functions.
+Registers are read and written via the standard HDA processing coefficient
+verbs (Set/Get Coefficient Index, Set/Get Processing Coefficient). The node is
+named "Realtek Vendor Registers" in public datasheets' verb listings and,
+apart from that, is entirely undocumented.
+
+This particular register, exposed at coefficient 0x36 and named in commits from
+Realtek, is of note: unlike most registers, which seem to control detailed
+amplifier parameters not in scope of the HDA specification, it controls audio
+routing which could just as easily have been defined using standard HDA mixer
+and selector widgets.
+
+Specifically, it selects between two sources for the input pin widget with Node
+ID (NID) 1Ah: the widget's signal can come either from an audio jack (on my
+laptop, a Dell XPS 13 9350, it's the headphone jack, but comments in Realtek
+commits indicate that it might be a Line In on some machines) or from the PC
+Beep line (which is itself multiplexed between the codec's internal beep
+generator and external PCBEEP pin, depending on if the beep generator is
+enabled via verbs on NID 01h). Additionally, it can mix (with optional
+amplification) that signal onto the 21h and/or 14h output pins.
+
+The register's reset value is 0x3717, corresponding to PC Beep on 1Ah that is
+then amplified and mixed into both the headphones and the speakers. Not only
+does this violate the HDA specification, which says that "[a vendor defined
+beep input pin] connection may be maintained *only* while the Link reset
+(**RST#**) is asserted", it means that we cannot ignore the register if we care
+about the input that 1Ah would otherwise expose or if the PCBEEP trace is
+poorly shielded and picks up chassis noise (both of which are the case on my
+machine).
+
+Unfortunately, there are lots of ways to get this register configuration wrong.
+Linux, it seems, has gone through most of them. For one, the register resets
+after S3 suspend: judging by existing code, this isn't the case for all vendor
+registers, and it's led to some fixes that improve behavior on cold boot but
+don't last after suspend. Other fixes have successfully switched the 1Ah input
+away from PC Beep but have failed to disable both loopback paths. On my
+machine, this means that the headphone input is amplified and looped back to
+the headphone output, which uses the exact same pins! As you might expect, this
+causes terrible headphone noise, the character of which is controlled by the
+1Ah boost control. (If you've seen instructions online to fix XPS 13 headphone
+noise by changing "Headphone Mic Boost" in ALSA, now you know why.)
+
+The information here has been obtained through black-box reverse engineering of
+the ALC256 codec's behavior and is not guaranteed to be correct. It likely
+also applies for the ALC255, ALC257, ALC235, and ALC236, since those codecs
+seem to be close relatives of the ALC256. (They all share one initialization
+function.) Additionally, other codecs like the ALC225 and ALC285 also have this
+register, judging by existing fixups in ``patch_realtek.c``, but specific
+data (e.g. node IDs, bit positions, pin mappings) for those codecs may differ
+from what I've described here.

+CoreSight Embedded Cross Trigger (CTI & CTM).
+=============================================
+
+    :Author:   Mike Leach <mike.leach@linaro.org>
+    :Date:     November 2019
+
+Hardware Description
+--------------------
+
+The CoreSight Cross Trigger Interface (CTI) is a hardware device that takes
+individual input and output hardware signals known as triggers to and from
+devices and interconnects them via the Cross Trigger Matrix (CTM) to other
+devices via numbered channels, in order to propagate events between devices.
+
+e.g.::
+
+ 0000000  in_trigs  :::::::
+ 0 C   0----------->:     :             +======>(other CTI channel IO)
+ 0  P  0<-----------:     :             v
+ 0   U 0  out_trigs :     : Channels  *****      :::::::
+ 0000000            : CTI :<=========>*CTM*<====>: CTI :---+
+ #######  in_trigs  :     : (id 0-3)  *****      :::::::   v
+ # ETM #----------->:     :                         ^   #######
+ #     #<-----------:     :                         +---# ETR #
+ ####### out_trigs  :::::::                             #######
+
+The CTI driver enables the programming of the CTI to attach triggers to
+channels. When an input trigger becomes active, the attached channel will
+become active. Any output trigger attached to that channel will also
+become active. The active channel is propagated to other CTIs via the CTM,
+activating connected output triggers there, unless filtered by the CTI
+channel gate.
+
+It is also possible to activate a channel using system software directly
+programming registers in the CTI.
+
+The CTIs are registered by the system to be associated with CPUs and/or other
+CoreSight devices on the trace data path. When these devices are enabled the
+attached CTIs will also be enabled. By default/on power up the CTIs have
+no programmed trigger/channel attachments, so will not affect the system
+until explicitly programmed.
+
+The hardware trigger connections between CTIs and devices is implementation
+defined, unless the CPU/ETM combination is a v8 architecture, in which case
+the connections have an architecturally defined standard layout.
+
+The hardware trigger signals can also be connected to non-CoreSight devices
+(e.g. UART), or be propagated off chip as hardware IO lines.
+
+All the CTI devices are associated with a CTM. On many systems there will be a
+single effective CTM (one CTM, or multiple CTMs all interconnected), but it is
+possible that systems can have nets of CTIs+CTM that are not interconnected by
+a CTM to each other. On these systems a CTM index is declared to associate
+CTI devices that are interconnected via a given CTM.
+
+Sysfs files and directories
+---------------------------
+
+The CTI devices appear on the existing CoreSight bus alongside the other
+CoreSight devices::
+
+    >$ ls /sys/bus/coresight/devices
+     cti_cpu0  cti_cpu2  cti_sys0  etm0  etm2  funnel0  replicator0  tmc_etr0
+     cti_cpu1  cti_cpu3  cti_sys1  etm1  etm3  funnel1  tmc_etf0     tpiu0
+
+The ``cti_cpu<N>`` named CTIs are associated with a CPU, and any ETM used by
+that core. The ``cti_sys<N>`` CTIs are general system infrastructure CTIs that
+can be associated with other CoreSight devices, or other system hardware
+capable of generating or using trigger signals.::
+
+  >$ ls /sys/bus/coresight/devices/etm0/cti_cpu0
+  channels  ctmid  enable  nr_trigger_cons mgmt  power powered  regs
+  subsystem triggers0 triggers1  uevent
+
+*Key file items are:-*
+   * ``enable``: enables/disables the CTI. Read to determine current state.
+     If this shows as enabled (1), but ``powered`` shows unpowered (0), then
+     the enable indicates a request to enabled when the device is powered.
+   * ``ctmid`` : associated CTM - only relevant if system has multiple CTI+CTM
+     clusters that are not interconnected.
+   * ``nr_trigger_cons`` : total connections - triggers<N> directories.
+   * ``powered`` : Read to determine if the CTI is currently powered.
+
+*Sub-directories:-*
+   * ``triggers<N>``: contains list of triggers for an individual connection.
+   * ``channels``: Contains the channel API - CTI main programming interface.
+   * ``regs``: Gives access to the raw programmable CTI regs.
+   * ``mgmt``: the standard CoreSight management registers.
+
+
+triggers<N> directories
+~~~~~~~~~~~~~~~~~~~~~~~
+
+Individual trigger connection information. This describes trigger signals for
+CoreSight and non-CoreSight connections.
+
+Each triggers directory has a set of parameters describing the triggers for
+the connection.
+
+   * ``name`` : name of connection
+   * ``in_signals`` : input trigger signal indexes used in this connection.
+   * ``in_types`` : functional types for in signals.
+   * ``out_signals`` : output trigger signals for this connection.
+   * ``out_types`` : functional types for out signals.
+
+e.g::
+
+    >$ ls ./cti_cpu0/triggers0/
+    in_signals  in_types  name  out_signals  out_types
+    >$ cat ./cti_cpu0/triggers0/name
+    cpu0
+    >$ cat ./cti_cpu0/triggers0/out_signals
+    0-2
+    >$ cat ./cti_cpu0/triggers0/out_types
+    pe_edbgreq pe_dbgrestart pe_ctiirq
+    >$ cat ./cti_cpu0/triggers0/in_signals
+    0-1
+    >$ cat ./cti_cpu0/triggers0/in_types
+    pe_dbgtrigger pe_pmuirq
+
+If a connection has zero signals in either the 'in' or 'out' triggers then
+those parameters will be omitted.
+
+Channels API Directory
+~~~~~~~~~~~~~~~~~~~~~~
+
+This provides an easy way to attach triggers to channels, without needing
+the multiple register operations that are required if manipulating the
+'regs' sub-directory elements directly.
+
+A number of files provide this API::
+
+   >$ ls ./cti_sys0/channels/
+   chan_clear         chan_inuse      chan_xtrigs_out     trigin_attach
+   chan_free          chan_pulse      chan_xtrigs_reset   trigin_detach
+   chan_gate_disable  chan_set        chan_xtrigs_sel     trigout_attach
+   chan_gate_enable   chan_xtrigs_in  trig_filter_enable  trigout_detach
+   trigout_filtered
+
+Most access to these elements take the form::
+
+  echo <chan> [<trigger>] > /<device_path>/<operation>
+
+where the optional <trigger> is only needed for trigXX_attach | detach
+operations.
+
+e.g.::
+
+   >$ echo 0 1 > ./cti_sys0/channels/trigout_attach
+   >$ echo 0 > ./cti_sys0/channels/chan_set
+
+Attaches trigout(1) to channel(0), then activates channel(0) generating a
+set state on cti_sys0.trigout(1)
+
+
+*API operations*
+
+   * ``trigin_attach, trigout_attach``: Attach a channel to a trigger signal.
+   * ``trigin_detach, trigout_detach``: Detach a channel from a trigger signal.
+   * ``chan_set``: Set the channel - the set state will be propagated around
+     the CTM to other connected devices.
+   * ``chan_clear``: Clear the channel.
+   * ``chan_pulse``: Set the channel for a single CoreSight clock cycle.
+   * ``chan_gate_enable``: Write operation sets the CTI gate to propagate
+     (enable) the channel to other devices. This operation takes a channel
+     number. CTI gate is enabled for all channels by default at power up. Read
+     to list the currently enabled channels on the gate.
+   * ``chan_gate_disable``: Write channel number to disable gate for that
+     channel.
+   * ``chan_inuse``: Show the current channels attached to any signal
+   * ``chan_free``: Show channels with no attached signals.
+   * ``chan_xtrigs_sel``: write a channel number to select a channel to view,
+     read to show the selected channel number.
+   * ``chan_xtrigs_in``: Read to show the input triggers attached to
+     the selected view channel.
+   * ``chan_xtrigs_out``:Read to show the output triggers attached to
+     the selected view channel.
+   * ``trig_filter_enable``: Defaults to enabled, disable to allow potentially
+     dangerous output signals to be set.
+   * ``trigout_filtered``: Trigger out signals that are prevented from being
+     set if filtering ``trig_filter_enable`` is enabled. One use is to prevent
+     accidental ``EDBGREQ`` signals stopping a core.
+   * ``chan_xtrigs_reset``: Write 1 to clear all channel / trigger programming.
+     Resets device hardware to default state.
+
+
+The example below attaches input trigger index 1 to channel 2, and output
+trigger index 6 to the same channel. It then examines the state of the
+channel / trigger connections using the appropriate sysfs attributes.
+
+The settings mean that if either input trigger 1, or channel 2 go active then
+trigger out 6 will go active. We then enable the CTI, and use the software
+channel control to activate channel 2. We see the active channel on the
+``choutstatus`` register and the active signal on the ``trigoutstatus``
+register. Finally clearing the channel removes this.
+
+e.g.::
+
+   .../cti_sys0/channels# echo 2 1 > trigin_attach
+   .../cti_sys0/channels# echo 2 6 > trigout_attach
+   .../cti_sys0/channels# cat chan_free
+   0-1,3
+   .../cti_sys0/channels# cat chan_inuse
+   2
+   .../cti_sys0/channels# echo 2 > chan_xtrigs_sel
+   .../cti_sys0/channels# cat chan_xtrigs_trigin
+   1
+   .../cti_sys0/channels# cat chan_xtrigs_trigout
+   6
+   .../cti_sys0/# echo 1 > enable
+   .../cti_sys0/channels# echo 2 > chan_set
+   .../cti_sys0/channels# cat ../regs/choutstatus
+   0x4
+   .../cti_sys0/channels# cat ../regs/trigoutstatus
+   0x40
+   .../cti_sys0/channels# echo 2 > chan_clear
+   .../cti_sys0/channels# cat ../regs/trigoutstatus
+   0x0
+   .../cti_sys0/channels# cat ../regs/choutstatus
+   0x0

+virtiofs: virtio-fs 主机<->客机共享文件系统
+===========================================
+
+- Copyright (C) 2020 Vivo Communication Technology Co. Ltd.
+
+介绍
+====
+Linux的virtiofs文件系统实现了一个半虚拟化VIRTIO类型“virtio-fs”设备的驱动，通过该\
+类型设备实现客机<->主机文件系统共享。它允许客机挂载一个已经导出到主机的目录。
+
+客机通常需要访问主机或者远程系统上的文件。使用场景包括：在新客机安装时让文件对其\
+可见；从主机上的根文件系统启动；对无状态或临时客机提供持久存储和在客机之间共享目录。
+
+尽管在某些任务可能通过使用已有的网络文件系统完成，但是却需要非常难以自动化的配置\
+步骤，且将存储网络暴露给客机。而virtio-fs设备通过提供不经过网络的文件系统访问文件\
+的设计方式解决了这些问题。
+
+另外，virto-fs设备发挥了主客机共存的优点提高了性能，并且提供了网络文件系统所不具备
+的一些语义功能。
+
+用法
+====
+以``myfs``标签将文件系统挂载到``/mnt``:
+
+.. code-block:: sh
+
+  guest# mount -t virtiofs myfs /mnt
+
+请查阅 https://virtio-fs.gitlab.io/ 了解配置QEMU和virtiofsd守护程序的详细信息。
+
+内幕
+====
+由于virtio-fs设备将FUSE协议用于文件系统请求，因此Linux的virtiofs文件系统与FUSE文\
+件系统客户端紧密集成在一起。客机充当FUSE客户端而主机充当FUSE服务器，内核与用户空\
+间之间的/dev/fuse接口由virtio-fs设备接口代替。
+
+FUSE请求被置于虚拟队列中由主机处理。主机填充缓冲区中的响应部分，而客机处理请求的完成部分。
+
+将/dev/fuse映射到虚拟队列需要解决/dev/fuse和虚拟队列之间语义上的差异。每次读取\
+/dev/fuse设备时，FUSE客户端都可以选择要传输的请求，从而可以使某些请求优先于其他\
+请求。虚拟队列有其队列语义，无法更改已入队请求的顺序。在虚拟队列已满的情况下尤
+其关键，因为此时不可能加入高优先级的请求。为了解决此差异，virtio-fs设备采用“hiprio”\
+（高优先级）虚拟队列，专门用于有别于普通请求的高优先级请求。

+==============
+USB Raw Gadget
+==============
+
+USB Raw Gadget is a kernel module that provides a userspace interface for
+the USB Gadget subsystem. Essentially it allows to emulate USB devices
+from userspace. Enabled with CONFIG_USB_RAW_GADGET. Raw Gadget is
+currently a strictly debugging feature and shouldn't be used in
+production, use GadgetFS instead.
+
+Comparison to GadgetFS
+~~~~~~~~~~~~~~~~~~~~~~
+
+Raw Gadget is similar to GadgetFS, but provides a more low-level and
+direct access to the USB Gadget layer for the userspace. The key
+differences are:
+
+1. Every USB request is passed to the userspace to get a response, while
+   GadgetFS responds to some USB requests internally based on the provided
+   descriptors. However note, that the UDC driver might respond to some
+   requests on its own and never forward them to the Gadget layer.
+
+2. GadgetFS performs some sanity checks on the provided USB descriptors,
+   while Raw Gadget allows you to provide arbitrary data as responses to
+   USB requests.
+
+3. Raw Gadget provides a way to select a UDC device/driver to bind to,
+   while GadgetFS currently binds to the first available UDC.
+
+4. Raw Gadget explicitly exposes information about endpoints addresses and
+   capabilities allowing a user to write UDC-agnostic gadgets.
+
+5. Raw Gadget has ioctl-based interface instead of a filesystem-based one.
+
+Userspace interface
+~~~~~~~~~~~~~~~~~~~
+
+To create a Raw Gadget instance open /dev/raw-gadget. Multiple raw-gadget
+instances (bound to different UDCs) can be used at the same time. The
+interaction with the opened file happens through the ioctl() calls, see
+comments in include/uapi/linux/usb/raw_gadget.h for details.
+
+The typical usage of Raw Gadget looks like:
+
+1. Open Raw Gadget instance via /dev/raw-gadget.
+2. Initialize the instance via USB_RAW_IOCTL_INIT.
+3. Launch the instance with USB_RAW_IOCTL_RUN.
+4. In a loop issue USB_RAW_IOCTL_EVENT_FETCH calls to receive events from
+   Raw Gadget and react to those depending on what kind of USB device
+   needs to be emulated.
+
+Note, that some UDC drivers have fixed addresses assigned to endpoints, and
+therefore arbitrary endpoint addresses can't be used in the descriptors.
+Nevertheles, Raw Gadget provides a UDC-agnostic way to write USB gadgets.
+Once a USB_RAW_EVENT_CONNECT event is received via USB_RAW_IOCTL_EVENT_FETCH,
+the USB_RAW_IOCTL_EPS_INFO ioctl can be used to find out information about
+endpoints that the UDC driver has. Based on that information, the user must
+chose UDC endpoints that will be used for the gadget being emulated, and
+properly assign addresses in endpoint descriptors.
+
+You can find usage examples (along with a test suite) here:
+
+https://github.com/xairy/raw-gadget
+
+Internal details
+~~~~~~~~~~~~~~~~
+
+Currently every endpoint read/write ioctl submits a USB request and waits until
+its completion. This is the desired mode for coverage-guided fuzzing (as we'd
+like all USB request processing happen during the lifetime of a syscall),
+and must be kept in the implementation. (This might be slow for real world
+applications, thus the O_NONBLOCK improvement suggestion below.)
+
+Potential future improvements
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+- Report more events (suspend, resume, etc.) through USB_RAW_IOCTL_EVENT_FETCH.
+
+- Support O_NONBLOCK I/O.
+
+- Support USB 3 features (accept SS endpoint companion descriptor when
+  enabling endpoints; allow providing stream_id for bulk transfers).
+
+- Support ISO transfer features (expose frame_number for completed requests).

+- L0 – level-0; the bare metal host, running KVM
+
+- L1 – level-1 guest; a VM running on L0; also called the "guest
+  hypervisor", as it itself is capable of running KVM.
+
+- L2 – level-2 guest; a VM running on L1, this is the "nested guest"
+
+.. note:: The above diagram is modelled after the x86 architecture;
+          s390x, ppc64 and other architectures are likely to have
+          a different design for nesting.
+
+          For example, s390x always has an LPAR (LogicalPARtition)
+          hypervisor running on bare metal, adding another layer and
+          resulting in at least four levels in a nested setup — L0 (bare
+          metal, running the LPAR hypervisor), L1 (host hypervisor), L2
+          (guest hypervisor), L3 (nested guest).
+
+          This document will stick with the three-level terminology (L0,
+          L1, and L2) for all architectures; and will largely focus on
+          x86.
+
+
+Use Cases
+---------
+
+There are several scenarios where nested KVM can be useful, to name a
+few:
+
+- As a developer, you want to test your software on different operating
+  systems (OSes).  Instead of renting multiple VMs from a Cloud
+  Provider, using nested KVM lets you rent a large enough "guest
+  hypervisor" (level-1 guest).  This in turn allows you to create
+  multiple nested guests (level-2 guests), running different OSes, on
+  which you can develop and test your software.
+
+- Live migration of "guest hypervisors" and their nested guests, for
+  load balancing, disaster recovery, etc.
+
+- VM image creation tools (e.g. ``virt-install``,  etc) often run
+  their own VM, and users expect these to work inside a VM.
+
+- Some OSes use virtualization internally for security (e.g. to let
+  applications run safely in isolation).
+
+
+Enabling "nested" (x86)
+-----------------------
+
+From Linux kernel v4.19 onwards, the ``nested`` KVM parameter is enabled
+by default for Intel and AMD.  (Though your Linux distribution might
+override this default.)
+
+In case you are running a Linux kernel older than v4.19, to enable
+nesting, set the ``nested`` KVM module parameter to ``Y`` or ``1``.  To
+persist this setting across reboots, you can add it in a config file, as
+shown below:
+
+1. On the bare metal host (L0), list the kernel modules and ensure that
+   the KVM modules::
+
+    $ lsmod | grep -i kvm
+    kvm_intel             133627  0
+    kvm                   435079  1 kvm_intel
+
+2. Show information for ``kvm_intel`` module::
+
+    $ modinfo kvm_intel | grep -i nested
+    parm:           nested:bool
+
+3. For the nested KVM configuration to persist across reboots, place the
+   below in ``/etc/modprobed/kvm_intel.conf`` (create the file if it
+   doesn't exist)::
+
+    $ cat /etc/modprobe.d/kvm_intel.conf
+    options kvm-intel nested=y
+
+4. Unload and re-load the KVM Intel module::
+
+    $ sudo rmmod kvm-intel
+    $ sudo modprobe kvm-intel
+
+5. Verify if the ``nested`` parameter for KVM is enabled::
+
+    $ cat /sys/module/kvm_intel/parameters/nested
+    Y
+
+For AMD hosts, the process is the same as above, except that the module
+name is ``kvm-amd``.
+
+
+Additional nested-related kernel parameters (x86)
+-------------------------------------------------
+
+If your hardware is sufficiently advanced (Intel Haswell processor or
+higher, which has newer hardware virt extensions), the following
+additional features will also be enabled by default: "Shadow VMCS
+(Virtual Machine Control Structure)", APIC Virtualization on your bare
+metal host (L0).  Parameters for Intel hosts::
+
+    $ cat /sys/module/kvm_intel/parameters/enable_shadow_vmcs
+    Y
+
+    $ cat /sys/module/kvm_intel/parameters/enable_apicv
+    Y
+
+    $ cat /sys/module/kvm_intel/parameters/ept
+    Y
+
+.. note:: If you suspect your L2 (i.e. nested guest) is running slower,
+          ensure the above are enabled (particularly
+          ``enable_shadow_vmcs`` and ``ept``).
+
+
+Starting a nested guest (x86)
+-----------------------------
+
+Once your bare metal host (L0) is configured for nesting, you should be
+able to start an L1 guest with::
+
+    $ qemu-kvm -cpu host [...]
+
+The above will pass through the host CPU's capabilities as-is to the
+gues); or for better live migration compatibility, use a named CPU
+model supported by QEMU. e.g.::
+
+    $ qemu-kvm -cpu Haswell-noTSX-IBRS,vmx=on
+
+then the guest hypervisor will subsequently be capable of running a
+nested guest with accelerated KVM.
+
+
+Enabling "nested" (s390x)
+-------------------------
+
+1. On the host hypervisor (L0), enable the ``nested`` parameter on
+   s390x::
+
+    $ rmmod kvm
+    $ modprobe kvm nested=1
+
+.. note:: On s390x, the kernel parameter ``hpage`` is mutually exclusive
+          with the ``nested`` paramter — i.e. to be able to enable
+          ``nested``, the ``hpage`` parameter *must* be disabled.
+
+2. The guest hypervisor (L1) must be provided with the ``sie`` CPU
+   feature — with QEMU, this can be done by using "host passthrough"
+   (via the command-line ``-cpu host``).
+
+3. Now the KVM module can be loaded in the L1 (guest hypervisor)::
+
+    $ modprobe kvm
+
+
+Live migration with nested KVM
+------------------------------
+
+Migrating an L1 guest, with a  *live* nested guest in it, to another
+bare metal host, works as of Linux kernel 5.3 and QEMU 4.2.0 for
+Intel x86 systems, and even on older versions for s390x.
+
+On AMD systems, once an L1 guest has started an L2 guest, the L1 guest
+should no longer be migrated or saved (refer to QEMU documentation on
+"savevm"/"loadvm") until the L2 guest shuts down.  Attempting to migrate
+or save-and-load an L1 guest while an L2 guest is running will result in
+undefined behavior.  You might see a ``kernel BUG!`` entry in ``dmesg``, a
+kernel 'oops', or an outright kernel panic.  Such a migrated or loaded L1
+guest can no longer be considered stable or secure, and must be restarted.
+Migrating an L1 guest merely configured to support nesting, while not
+actually running L2 guests, is expected to function normally even on AMD
+systems but may fail once guests are started.
+
+Migrating an L2 guest is always expected to succeed, so all the following
+scenarios should work even on AMD systems:
+
+- Migrating a nested guest (L2) to another L1 guest on the *same* bare
+  metal host.
+
+- Migrating a nested guest (L2) to another L1 guest on a *different*
+  bare metal host.
+
+- Migrating a nested guest (L2) to a bare metal host.
+
+Reporting bugs from nested setups
+-----------------------------------
+
+Debugging "nested" problems can involve sifting through log files across
+L0, L1 and L2; this can result in tedious back-n-forth between the bug
+reporter and the bug fixer.
+
+- Mention that you are in a "nested" setup.  If you are running any kind
+  of "nesting" at all, say so.  Unfortunately, this needs to be called
+  out because when reporting bugs, people tend to forget to even
+  *mention* that they're using nested virtualization.
+
+- Ensure you are actually running KVM on KVM.  Sometimes people do not
+  have KVM enabled for their guest hypervisor (L1), which results in
+  them running with pure emulation or what QEMU calls it as "TCG", but
+  they think they're running nested KVM.  Thus confusing "nested Virt"
+  (which could also mean, QEMU on KVM) with "nested KVM" (KVM on KVM).
+
+Information to collect (generic)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The following is not an exhaustive list, but a very good starting point:
+
+  - Kernel, libvirt, and QEMU version from L0
+
+  - Kernel, libvirt and QEMU version from L1
+
+  - QEMU command-line of L1 -- when using libvirt, you'll find it here:
+    ``/var/log/libvirt/qemu/instance.log``
+
+  - QEMU command-line of L2 -- as above, when using libvirt, get the
+    complete libvirt-generated QEMU command-line
+
+  - ``cat /sys/cpuinfo`` from L0
+
+  - ``cat /sys/cpuinfo`` from L1
+
+  - ``lscpu`` from L0
+
+  - ``lscpu`` from L1
+
+  - Full ``dmesg`` output from L0
+
+  - Full ``dmesg`` output from L1
+
+x86-specific info to collect
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Both the below commands, ``x86info`` and ``dmidecode``, should be
+available on most Linux distributions with the same name:
+
+  - Output of: ``x86info -a`` from L0
+
+  - Output of: ``x86info -a`` from L1
+
+  - Output of: ``dmidecode`` from L0
+
+  - Output of: ``dmidecode`` from L1
+
+s390x-specific info to collect
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Along with the earlier mentioned generic details, the below is
+also recommended:
+
+  - ``/proc/sysinfo`` from L1; this will also include the info from L0

+======================================
+s390 (IBM Z) Boot/IPL of Protected VMs
+======================================
+
+Summary
+-------
+The memory of Protected Virtual Machines (PVMs) is not accessible to
+I/O or the hypervisor. In those cases where the hypervisor needs to
+access the memory of a PVM, that memory must be made accessible.
+Memory made accessible to the hypervisor will be encrypted. See
+:doc:`s390-pv` for details."
+
+On IPL (boot) a small plaintext bootloader is started, which provides
+information about the encrypted components and necessary metadata to
+KVM to decrypt the protected virtual machine.
+
+Based on this data, KVM will make the protected virtual machine known
+to the Ultravisor (UV) and instruct it to secure the memory of the
+PVM, decrypt the components and verify the data and address list
+hashes, to ensure integrity. Afterwards KVM can run the PVM via the
+SIE instruction which the UV will intercept and execute on KVM's
+behalf.
+
+As the guest image is just like an opaque kernel image that does the
+switch into PV mode itself, the user can load encrypted guest
+executables and data via every available method (network, dasd, scsi,
+direct kernel, ...) without the need to change the boot process.
+
+
+Diag308
+-------
+This diagnose instruction is the basic mechanism to handle IPL and
+related operations for virtual machines. The VM can set and retrieve
+IPL information blocks, that specify the IPL method/devices and
+request VM memory and subsystem resets, as well as IPLs.
+
+For PVMs this concept has been extended with new subcodes:
+
+Subcode 8: Set an IPL Information Block of type 5 (information block
+for PVMs)
+Subcode 9: Store the saved block in guest memory
+Subcode 10: Move into Protected Virtualization mode
+
+The new PV load-device-specific-parameters field specifies all data
+that is necessary to move into PV mode.
+
+* PV Header origin
+* PV Header length
+* List of Components composed of
+   * AES-XTS Tweak prefix
+   * Origin
+   * Size
+
+The PV header contains the keys and hashes, which the UV will use to
+decrypt and verify the PV, as well as control flags and a start PSW.
+
+The components are for instance an encrypted kernel, kernel parameters
+and initrd. The components are decrypted by the UV.
+
+After the initial import of the encrypted data, all defined pages will
+contain the guest content. All non-specified pages will start out as
+zero pages on first access.
+
+
+When running in protected virtualization mode, some subcodes will result in
+exceptions or return error codes.
+
+Subcodes 4 and 7, which specify operations that do not clear the guest
+memory, will result in specification exceptions. This is because the
+UV will clear all memory when a secure VM is removed, and therefore
+non-clearing IPL subcodes are not allowed.
+
+Subcodes 8, 9, 10 will result in specification exceptions.
+Re-IPL into a protected mode is only possible via a detour into non
+protected mode.
+
+Keys
+----
+Every CEC will have a unique public key to enable tooling to build
+encrypted images.
+See  `s390-tools <https://github.com/ibm-s390-tools/s390-tools/>`_
+for the tooling.

+=========================================
+s390 (IBM Z) Ultravisor and Protected VMs
+=========================================
+
+Summary
+-------
+Protected virtual machines (PVM) are KVM VMs that do not allow KVM to
+access VM state like guest memory or guest registers. Instead, the
+PVMs are mostly managed by a new entity called Ultravisor (UV). The UV
+provides an API that can be used by PVMs and KVM to request management
+actions.
+
+Each guest starts in non-protected mode and then may make a request to
+transition into protected mode. On transition, KVM registers the guest
+and its VCPUs with the Ultravisor and prepares everything for running
+it.
+
+The Ultravisor will secure and decrypt the guest's boot memory
+(i.e. kernel/initrd). It will safeguard state changes like VCPU
+starts/stops and injected interrupts while the guest is running.
+
+As access to the guest's state, such as the SIE state description, is
+normally needed to be able to run a VM, some changes have been made in
+the behavior of the SIE instruction. A new format 4 state description
+has been introduced, where some fields have different meanings for a
+PVM. SIE exits are minimized as much as possible to improve speed and
+reduce exposed guest state.
+
+
+Interrupt injection
+-------------------
+Interrupt injection is safeguarded by the Ultravisor. As KVM doesn't
+have access to the VCPUs' lowcores, injection is handled via the
+format 4 state description.
+
+Machine check, external, IO and restart interruptions each can be
+injected on SIE entry via a bit in the interrupt injection control
+field (offset 0x54). If the guest cpu is not enabled for the interrupt
+at the time of injection, a validity interception is recognized. The
+format 4 state description contains fields in the interception data
+block where data associated with the interrupt can be transported.
+
+Program and Service Call exceptions have another layer of
+safeguarding; they can only be injected for instructions that have
+been intercepted into KVM. The exceptions need to be a valid outcome
+of an instruction emulation by KVM, e.g. we can never inject a
+addressing exception as they are reported by SIE since KVM has no
+access to the guest memory.
+
+
+Mask notification interceptions
+-------------------------------
+KVM cannot intercept lctl(g) and lpsw(e) anymore in order to be
+notified when a PVM enables a certain class of interrupt.  As a
+replacement, two new interception codes have been introduced: One
+indicating that the contents of CRs 0, 6, or 14 have been changed,
+indicating different interruption subclasses; and one indicating that
+PSW bit 13 has been changed, indicating that a machine check
+intervention was requested and those are now enabled.
+
+Instruction emulation
+---------------------
+With the format 4 state description for PVMs, the SIE instruction already
+interprets more instructions than it does with format 2. It is not able
+to interpret every instruction, but needs to hand some tasks to KVM;
+therefore, the SIE and the ultravisor safeguard emulation inputs and outputs.
+
+The control structures associated with SIE provide the Secure
+Instruction Data Area (SIDA), the Interception Parameters (IP) and the
+Secure Interception General Register Save Area.  Guest GRs and most of
+the instruction data, such as I/O data structures, are filtered.
+Instruction data is copied to and from the SIDA when needed.  Guest
+GRs are put into / retrieved from the Secure Interception General
+Register Save Area.
+
+Only GR values needed to emulate an instruction will be copied into this
+save area and the real register numbers will be hidden.
+
+The Interception Parameters state description field still contains the
+the bytes of the instruction text, but with pre-set register values
+instead of the actual ones. I.e. each instruction always uses the same
+instruction text, in order not to leak guest instruction text.
+This also implies that the register content that a guest had in r<n>
+may be in r<m> from the hypervisor's point of view.
+
+The Secure Instruction Data Area contains instruction storage
+data. Instruction data, i.e. data being referenced by an instruction
+like the SCCB for sclp, is moved via the SIDA. When an instruction is
+intercepted, the SIE will only allow data and program interrupts for
+this instruction to be moved to the guest via the two data areas
+discussed before. Other data is either ignored or results in validity
+interceptions.
+
+
+Instruction emulation interceptions
+-----------------------------------
+There are two types of SIE secure instruction intercepts: the normal
+and the notification type. Normal secure instruction intercepts will
+make the guest pending for instruction completion of the intercepted
+instruction type, i.e. on SIE entry it is attempted to complete
+emulation of the instruction with the data provided by KVM. That might
+be a program exception or instruction completion.
+
+The notification type intercepts inform KVM about guest environment
+changes due to guest instruction interpretation. Such an interception
+is recognized, for example, for the store prefix instruction to provide
+the new lowcore location. On SIE reentry, any KVM data in the data areas
+is ignored and execution continues as if the guest instruction had
+completed. For that reason KVM is not allowed to inject a program
+interrupt.

+.. _free_page_reporting:
+
+=====================
+Free Page Reporting
+=====================
+
+Free page reporting is an API by which a device can register to receive
+lists of pages that are currently unused by the system. This is useful in
+the case of virtualization where a guest is then able to use this data to
+notify the hypervisor that it is no longer using certain pages in memory.
+
+For the driver, typically a balloon driver, to use of this functionality
+it will allocate and initialize a page_reporting_dev_info structure. The
+field within the structure it will populate is the "report" function
+pointer used to process the scatterlist. It must also guarantee that it can
+handle at least PAGE_REPORTING_CAPACITY worth of scatterlist entries per
+call to the function. A call to page_reporting_register will register the
+page reporting interface with the reporting framework assuming no other
+page reporting devices are already registered.
+
+Once registered the page reporting API will begin reporting batches of
+pages to the driver. The API will start reporting pages 2 seconds after
+the interface is registered and will continue to do so 2 seconds after any
+page of a sufficiently high order is freed.
+
+Pages reported will be stored in the scatterlist passed to the reporting
+function with the final entry having the end bit set in entry nent - 1.
+While pages are being processed by the report function they will not be
+accessible to the allocator. Once the report function has been completed
+the pages will be returned to the free area from which they were obtained.
+
+Prior to removing a driver that is making use of free page reporting it
+is necessary to call page_reporting_unregister to have the
+page_reporting_dev_info structure that is currently in use by free page
+reporting removed. Doing this will prevent further reports from being
+issued via the interface. If another driver or the same driver is
+registered it is possible for it to resume where the previous driver had
+left off in terms of reporting free pages.

+CONFIG_BUILDTIME_TABLE_SORT allows the __ex_table section to be sorted post

+occurs we can quickly lookup the __ex_table entry via binary search.

-/********************************************************************
- * Hypervisor exception vector and handlers
- *
- *
- * The KVM/ARM Hypervisor ABI is defined as follows:
- *
- * Entry to Hyp mode from the host kernel will happen _only_ when an HVC
- * instruction is issued since all traps are disabled when running the host
- * kernel as per the Hyp-mode initialization at boot time.
- *
- * HVC instructions cause a trap to the vector page + offset 0x14 (see hyp_hvc
- * below) when the HVC instruction is called from SVC mode (i.e. a guest or the
- * host kernel) and they cause a trap to the vector page + offset 0x8 when HVC
- * instructions are called from within Hyp-mode.
- *
- * Hyp-ABI: Calling HYP-mode functions from host (in SVC mode):
- *    Switching to Hyp mode is done through a simple HVC #0 instruction. The
- *    exception vector code will check that the HVC comes from VMID==0.
- *    - r0 contains a pointer to a HYP function
- *    - r1, r2, and r3 contain arguments to the above function.
- *    - The HYP function will be called with its arguments in r0, r1 and r2.
- *    On HYP function return, we return directly to SVC.
- *
- * Note that the above is used to execute code in Hyp-mode from a host-kernel
- * point of view, and is a different concept from performing a world-switch and
- * executing guest code SVC mode (with a VMID != 0).

- * Another possibility is to get a HYP stub hypercall.

+ * MSR[HV]=1  (e.g., bare metal kernel and userspace). So these interrupts do
+ * not need to test whether a guest is running because they get delivered to
+ * the guest directly, including nested HV KVM guests.
+ *
+ * The exception is PR KVM, where the guest runs with MSR[PR]=1 and the host
+ * runs with MSR[HV]=0, so the host takes all interrupts on behalf of the

+ * Interrupts that are taken in MSR[HV]=0 and escalate to MSR[HV]=1 are always

+ * Interrupt 0x100 - System Reset Interrupt (SRESET aka NMI).
+ * This is a non-maskable, asynchronous interrupt always taken in real-mode.
+ * It is caused by:
+ * - Wake from power-saving state, on powernv.
+ * - An NMI from another CPU, triggered by firmware or hypercall.
+ * - As crash/debug signal injected from BMC, firmware or hypervisor.
+ *
+ * Handling:
+ * Power-save wakeup is the only performance critical path, so this is
+ * determined quickly as possible first. In this case volatile registers
+ * can be discarded and SPRs like CFAR don't need to be read.
+ *
+ * If not a powersave wakeup, then it's run as a regular interrupt, however
+ * it uses its own stack and PACA save area to preserve the regular kernel
+ * environment for debugging.
+ *
+ * This interrupt is not maskable, so triggering it when MSR[RI] is clear,
+ * or SCRATCH0 is in use, etc. may cause a crash. It's also not entirely
+ * correct to switch to virtual mode to run the regular interrupt handler
+ * because it might be interrupted when the MMU is in a bad state (e.g., SLB
+ * is clear).
+ *
+ * FWNMI:
+ * PAPR specifies a "fwnmi" facility which sends the sreset to a different
+ * entry point with a different register set up. Some hypervisors will
+ * send the sreset to 0x100 in the guest if it is not fwnmi capable.
+ *
+ * KVM:
+ * Unlike most SRR interrupts, this may be taken by the host while executing
+ * in a guest, so a KVM test is required. KVM will pull the CPU out of guest
+ * mode and then raise the sreset.

+/**
+ * Interrupt 0x200 - Machine Check Interrupt (MCE).
+ * This is a non-maskable interrupt always taken in real-mode. It can be
+ * synchronous or asynchronous, caused by hardware or software, and it may be
+ * taken in a power-saving state.
+ *
+ * Handling:
+ * Similarly to system reset, this uses its own stack and PACA save area,
+ * the difference is re-entrancy is allowed on the machine check stack.
+ *
+ * machine_check_early is run in real mode, and carefully decodes the
+ * machine check and tries to handle it (e.g., flush the SLB if there was an
+ * error detected there), determines if it was recoverable and logs the
+ * event.
+ *
+ * This early code does not "reconcile" irq soft-mask state like SRESET or
+ * regular interrupts do, so irqs_disabled() among other things may not work
+ * properly (irq disable/enable already doesn't work because irq tracing can
+ * not work in real mode).
+ *
+ * Then, depending on the execution context when the interrupt is taken, there
+ * are 3 main actions:
+ * - Executing in kernel mode. The event is queued with irq_work, which means
+ *   it is handled when it is next safe to do so (i.e., the kernel has enabled
+ *   interrupts), which could be immediately when the interrupt returns. This
+ *   avoids nasty issues like switching to virtual mode when the MMU is in a
+ *   bad state, or when executing OPAL code. (SRESET is exposed to such issues,
+ *   but it has different priorities). Check to see if the CPU was in power
+ *   save, and return via the wake up code if it was.
+ *
+ * - Executing in user mode. machine_check_exception is run like a normal
+ *   interrupt handler, which processes the data generated by the early handler.
+ *
+ * - Executing in guest mode. The interrupt is run with its KVM test, and
+ *   branches to KVM to deal with. KVM may queue the event for the host
+ *   to report later.
+ *
+ * This interrupt is not maskable, so if it triggers when MSR[RI] is clear,
+ * or SCRATCH0 is in use, it may cause a crash.
+ *

+ * See SRESET.

+ * The registers are decoded according to the ABI:

+ * 32-bit: EBX, ECX, EDX, ESI, EDI, EBP
+ *
+ * The stub then passes the decoded arguments to the __se_sys_*() wrapper to

+ * arguments are passed to the __do_sys_*() function which is the actual
+ * syscall.  These wrappers are marked as inline so the compiler can optimize
+ * the functions where appropriate.

+ *	cltq			<-- extend return value to 64-bit
+ *	retq			<-- return

- * Instead of the generic __SYSCALL_DEFINEx() definition, this macro takes
- * struct pt_regs *regs as the only argument of the syscall stub named
- * __x64_sys_*(). It decodes just the registers it needs and passes them on to
- * the __se_sys_*() wrapper performing sign extension and then to the
- * __do_sys_*() function doing the actual job. These wrappers and functions
- * are inlined (at least in very most cases), meaning that the assembly looks
- * as follows (slightly re-ordered for better readability):
- *
- * <__x64_sys_recv>:		<-- syscall with 4 parameters
- *	callq	<__fentry__>
- *
- *	mov	0x70(%rdi),%rdi	<-- decode regs->di
- *	mov	0x68(%rdi),%rsi	<-- decode regs->si
- *	mov	0x60(%rdi),%rdx	<-- decode regs->dx
- *	mov	0x38(%rdi),%rcx	<-- decode regs->r10
- *
- *	xor	%r9d,%r9d	<-- clear %r9
- *	xor	%r8d,%r8d	<-- clear %r8
- *
- *	callq	__sys_recvfrom	<-- do the actual work in __sys_recvfrom()
- *				    which takes 6 arguments
- *
- *	cltq			<-- extend return value to 64-bit
- *	retq			<-- return
- *
- * This approach avoids leaking random user-provided register content down
- * the call chain.
- *
- * If IA32_EMULATION is enabled, this macro generates an additional wrapper
- * named __ia32_sys_*() which decodes the struct pt_regs *regs according
- * to the i386 calling convention (bx, cx, dx, si, di, bp).

+ * (freq_curr/freq_max would rarely reach 1) and something close to freq_base,
+ * which would ignore the entire turbo range (a conspicuous part, making
+ * freq_curr/freq_max always maxed out).
+ *
+ * An exception to the heuristic above is the Atom uarch, where we choose the
+ * highest turbo level for freq_max since Atom's are generally oriented towards
+ * power efficiency.

+ * Setting freq_max to anything less than the 1C turbo ratio makes the ratio
+ * freq_curr / freq_max to eventually grow >1, in which case we clip it to 1.

 /*
- * If the basic or extended CPUID leaf requested is higher than the
- * maximum supported basic or extended leaf, respectively, then it is
- * out of range.
+ * Intel CPUID semantics treats any query for an out-of-range leaf as if the
+ * highest basic leaf (i.e. CPUID.0H:EAX) were requested.  AMD CPUID semantics
+ * returns all zeroes for any undefined leaf, whether or not the leaf is in
+ * range.  Centaur/VIA follows Intel semantics.
+ *
+ * A leaf is considered out-of-range if its function is higher than the maximum
+ * supported leaf of its associated class or if its associated class does not
+ * exist.
+ *
+ * There are three primary classes to be considered, with their respective
+ * ranges described as "<base> - <top>[,<base2> - <top2>] inclusive.  A primary
+ * class exists if a guest CPUID entry for its <base> leaf exists.  For a given
+ * class, CPUID.<base>.EAX contains the max supported leaf for the class.
+ *
+ *  - Basic:      0x00000000 - 0x3fffffff, 0x50000000 - 0x7fffffff
+ *  - Hypervisor: 0x40000000 - 0x4fffffff
+ *  - Extended:   0x80000000 - 0xbfffffff
+ *  - Centaur:    0xc0000000 - 0xcfffffff
+ *
+ * The Hypervisor class is further subdivided into sub-classes that each act as
+ * their own indepdent class associated with a 0x100 byte range.  E.g. if Qemu
+ * is advertising support for both HyperV and KVM, the resulting Hypervisor
+ * CPUID sub-classes are:
+ *
+ *  - HyperV:     0x40000000 - 0x400000ff
+ *  - KVM:        0x40000100 - 0x400001ff

- * blk_queue_make_request - define an alternate make_request function for a device
- * @q:  the request queue for the device to be affected
- * @mfn: the alternate make_request function
- *
- * Description:
- *    The normal way for &struct bios to be passed to a device
- *    driver is for them to be collected into requests on a request
- *    queue, and then to allow the device driver to select requests
- *    off that queue when it is ready.  This works well for many block
- *    devices. However some block devices (typically virtual devices
- *    such as md or lvm) do not benefit from the processing on the
- *    request queue, and are served best by having the requests passed
- *    directly to them.  This can be achieved by providing a function
- *    to blk_queue_make_request().
- *
- * Caveat:
- *    The driver that does this *must* be able to deal appropriately
- *    with buffers in "highmemory". This can be accomplished by either calling
- *    kmap_atomic() to get a temporary kernel mapping, or by calling
- *    blk_queue_bounce() to create a buffer in normal memory.

- *	In libata, a port contains links and a link contains devices.

- *
- *	However, there are a few controllers which don't fit into this

- *	interface with both master and slave devices but also have
- *	separate SCR register sets for each device.  These controllers
- *	need separate links for physical link handling

- *	handling, separate @ap->slave_link is used.  All dirty details
- *	are implemented inside libata core layer.  From LLD's POV, the
- *	only difference is that prereset, hardreset and postreset are
- *	called once more for the slave link, so the reset sequence
- *	looks like the following.
- *
- *	prereset(M) -> prereset(S) -> hardreset(M) -> hardreset(S) ->
- *	softreset(M) -> postreset(M) -> postreset(S)
- *

+ *
+ *	In libata, a port contains links and a link contains devices.
+ *	There is single host link but if a PMP is attached to it,

+ *	controllers emulating TF based interface can have two - master

+ *
+ *	However, there are a few controllers which don't fit into this

+ *	interface with both master and slave devices but also have
+ *	separate SCR register sets for each device.  These controllers
+ *	need separate links for physical link handling

+ *	slave_link is libata's way of handling this class of
+ *	controllers without impacting core layer too much.  For
+ *	anything other than physical link handling, the default host
+ *	link is used for both master and slave.  For physical link
+ *	handling, separate @ap->slave_link is used.  All dirty details
+ *	are implemented inside libata core layer.  From LLD's POV, the
+ *	only difference is that prereset, hardreset and postreset are
+ *	called once more for the slave link, so the reset sequence
+ *	looks like the following.
+ *
+ *	prereset(M) -> prereset(S) -> hardreset(M) -> hardreset(S) ->
+ *	softreset(M) -> postreset(M) -> postreset(S)

+ * Priority increases as we go down. For instance, from any state in L0, the
+ * transition can be made to states in L1, L2 and L3. A notable exception to
+ * this rule is state DISABLE.  From DISABLE state we can only transition to
+ * POR state. Also, while in L2 state, user cannot jump back to previous
+ * L1 or L0 states.
+ *
+ * Valid transitions:
+ * L0: DISABLE <--> POR
+ *     POR <--> POR
+ *     POR -> M0 -> M2 --> M0
+ *     POR -> FW_DL_ERR
+ *     FW_DL_ERR <--> FW_DL_ERR

+ *     M0 -> FW_DL_ERR
+ *     M0 -> M3_ENTER -> M3 -> M3_EXIT --> M0

- *
- * Based on skeleton from the drivers/char/rtc.c driver by P. Gortmaker
- *
- * This code provides an architected & portable interface to the real time
- * clock by using EFI instead of direct bit fiddling. The functionalities are 
- * quite different from the rtc.c driver. The only way to talk to the device 
- * is by using ioctl(). There is a /proc interface which provides the raw 
- * information.
- *
- * Please note that we have kept the API as close as possible to the
- * legacy RTC. The standard /sbin/hwclock program should work normally 
- * when used to get/set the time.
- *
- * NOTES:
- *	- Locking is required for safe execution of EFI calls with regards
- *	  to interrupts and SMP.
- *
- * TODO (December 1999):
- * 	- provide the API to set/get the WakeUp Alarm (different from the
- *	  rtc.c alarm).
- *	- SMP testing
- * 	- Add module support

- *	Real Time Clock interface for Linux
- *
- *	Copyright (C) 1996 Paul Gortmaker
- *
- *	This driver allows use of the real time clock (built into
- *	nearly all computers) from user space. It exports the /dev/rtc
- *	interface supporting various ioctl() and also the
- *	/proc/driver/rtc pseudo-file for status information.
- *
- *	The ioctls can be used to set the interrupt behaviour and
- *	generation rate from the RTC via IRQ 8. Then the /dev/rtc
- *	interface can be used to make use of these timer interrupts,
- *	be they interval or alarm based.
- *
- *	The /dev/rtc interface will block on reads until an interrupt
- *	has been received. If a RTC interrupt has already happened,
- *	it will output an unsigned long and then block. The output value
- *	contains the interrupt status in the low byte and the number of
- *	interrupts since the last read in the remaining high bytes. The
- *	/dev/rtc interface can also be used with the select(2) call.
- *
- *	Based on other minimal char device drivers, like Alan's
- *	watchdog, Ted's random, etc. etc.
- *
- *	1.07	Paul Gortmaker.
- *	1.08	Miquel van Smoorenburg: disallow certain things on the
- *		DEC Alpha as the CMOS clock is also used for other things.

+ *	* When CPT()_VQ()_DONE_ENA_W1S[DONE] = 0, interrupts are not sent,

+ *	Since CPT instructions complete out-of-order, if software is using

+ * 	first call to write 4096 -> PSP fails
+ * 	Second call to write 1000 -> PSP Pass -> SRM is set
+ *
+ * Example 2:
+ * 	Bad SRM size = 4096
+ * 	first call to write 4096 -> PSP fails (This is the same as above, but we don't know if this
+ * 	is the last call)
+ *
+ * Solution?:
+ * 	1: Parse the SRM? -> It is signed so we don't know the EOF
+ * 	2: We can have another sysfs that passes the size before calling set. -> simpler solution
+ * 	below
+ *
+ * Easy Solution:
+ * Always call get after Set to verify if set was successful.
+ * +----------------------+
+ * |   Why it works:      |
+ * +----------------------+
+ * PSP will only update its srm if its older than the one we are trying to load.
+ * Always do set first than get.
+ * 	-if we try to "1. SET" a older version PSP will reject it and we can "2. GET" the newer
+ * 	version and save it
+ *
+ * 	-if we try to "1. SET" a newer version PSP will accept it and we can "2. GET" the
+ * 	same(newer) version back and save it
+ *
+ * 	-if we try to "1. SET" a newer version and PSP rejects it. That means the format is
+ * 	incorrect/corrupted and we should correct our SRM by getting it from PSP

 /**
- * DOC: bridge callbacks
+ * DOC: bridge operations
+ *
+ * Bridge drivers expose operations through the &drm_bridge_funcs structure.
+ * The DRM internals (atomic and CRTC helpers) use the helpers defined in
+ * drm_bridge.c to call bridge operations. Those operations are divided in
+ * three big categories to support different parts of the bridge usage.
+ *
+ * - The encoder-related operations support control of the bridges in the
+ *   chain, and are roughly counterparts to the &drm_encoder_helper_funcs
+ *   operations. They are used by the legacy CRTC and the atomic modeset
+ *   helpers to perform mode validation, fixup and setting, and enable and
+ *   disable the bridge automatically.
+ *
+ *   The enable and disable operations are split in
+ *   &drm_bridge_funcs.pre_enable, &drm_bridge_funcs.enable,
+ *   &drm_bridge_funcs.disable and &drm_bridge_funcs.post_disable to provide
+ *   finer-grained control.
+ *
+ *   Bridge drivers may implement the legacy version of those operations, or
+ *   the atomic version (prefixed with atomic\_), in which case they shall also
+ *   implement the atomic state bookkeeping operations
+ *   (&drm_bridge_funcs.atomic_duplicate_state,
+ *   &drm_bridge_funcs.atomic_destroy_state and &drm_bridge_funcs.reset).
+ *   Mixing atomic and non-atomic versions of the operations is not supported.
+ *
+ * - The bus format negotiation operations
+ *   &drm_bridge_funcs.atomic_get_output_bus_fmts and
+ *   &drm_bridge_funcs.atomic_get_input_bus_fmts allow bridge drivers to
+ *   negotiate the formats transmitted between bridges in the chain when
+ *   multiple formats are supported. Negotiation for formats is performed
+ *   transparently for display drivers by the atomic modeset helpers. Only
+ *   atomic versions of those operations exist, bridge drivers that need to
+ *   implement them shall thus also implement the atomic version of the
+ *   encoder-related operations. This feature is not supported by the legacy
+ *   CRTC helpers.
+ *
+ * - The connector-related operations support implementing a &drm_connector
+ *   based on a chain of bridges. DRM bridges traditionally create a
+ *   &drm_connector for bridges meant to be used at the end of the chain. This
+ *   puts additional burden on bridge drivers, especially for bridges that may
+ *   be used in the middle of a chain or at the end of it. Furthermore, it
+ *   requires all operations of the &drm_connector to be handled by a single
+ *   bridge, which doesn't always match the hardware architecture.
+ *
+ *   To simplify bridge drivers and make the connector implementation more
+ *   flexible, a new model allows bridges to unconditionally skip creation of
+ *   &drm_connector and instead expose &drm_bridge_funcs operations to support
+ *   an externally-implemented &drm_connector. Those operations are
+ *   &drm_bridge_funcs.detect, &drm_bridge_funcs.get_modes,
+ *   &drm_bridge_funcs.get_edid, &drm_bridge_funcs.hpd_notify,
+ *   &drm_bridge_funcs.hpd_enable and &drm_bridge_funcs.hpd_disable. When
+ *   implemented, display drivers shall create a &drm_connector instance for
+ *   each chain of bridges, and implement those connector instances based on
+ *   the bridge connector operations.
  *
- * The &drm_bridge_funcs ops are populated by the bridge driver. The DRM
- * internals (atomic and CRTC helpers) use the helpers defined in drm_bridge.c
- * These helpers call a specific &drm_bridge_funcs op for all the bridges
- * during encoder configuration.
+ *   Bridge drivers shall implement the connector-related operations for all
+ *   the features that the bridge hardware support. For instance, if a bridge
+ *   supports reading EDID, the &drm_bridge_funcs.get_edid shall be
+ *   implemented. This however doesn't mean that the DDC lines are wired to the
+ *   bridge on a particular platform, as they could also be connected to an I2C
+ *   controller of the SoC. Support for the connector-related operations on the
+ *   running platform is reported through the &drm_bridge.ops flags. Bridge
+ *   drivers shall detect which operations they can support on the platform
+ *   (usually this information is provided by ACPI or DT), and set the
+ *   &drm_bridge.ops flags for all supported operations. A flag shall only be
+ *   set if the corresponding &drm_bridge_funcs operation is implemented, but
+ *   an implemented operation doesn't necessarily imply that the corresponding
+ *   flag will be set. Display drivers shall use the &drm_bridge.ops flags to
+ *   decide which bridge to delegate a connector operation to. This mechanism
+ *   allows providing a single static const &drm_bridge_funcs instance in
+ *   bridge drivers, improving security by storing function pointers in
+ *   read-only memory.
  *
- * For detailed specification of the bridge callbacks see &drm_bridge_funcs.
+ *   In order to ease transition, bridge drivers may support both the old and
+ *   new models by making connector creation optional and implementing the
+ *   connected-related bridge operations. Connector creation is then controlled
+ *   by the flags argument to the drm_bridge_attach() function. Display drivers
+ *   that support the new model and create connectors themselves shall set the
+ *   %DRM_BRIDGE_ATTACH_NO_CONNECTOR flag, and bridge drivers shall then skip
+ *   connector creation. For intermediate bridges in the chain, the flag shall
+ *   be passed to the drm_bridge_attach() call for the downstream bridge.
+ *   Bridge drivers that implement the new model only shall return an error
+ *   from their &drm_bridge_funcs.attach handler when the
+ *   %DRM_BRIDGE_ATTACH_NO_CONNECTOR flag is not set. New display drivers
+ *   should use the new model, and convert the bridge drivers they use if
+ *   needed, in order to gradually transition to the new model.

+/**
+ * DOC: overview
+ *
+ * The DRM bridge connector helper object provides a DRM connector
+ * implementation that wraps a chain of &struct drm_bridge. The connector
+ * operations are fully implemented based on the operations of the bridges in
+ * the chain, and don't require any intervention from the display controller
+ * driver at runtime.
+ *
+ * To use the helper, display controller drivers create a bridge connector with
+ * a call to drm_bridge_connector_init(). This associates the newly created
+ * connector with the chain of bridges passed to the function and registers it
+ * with the DRM device. At that point the connector becomes fully usable, no
+ * further operation is needed.
+ *
+ * The DRM bridge connector operations are implemented based on the operations
+ * provided by the bridges in the chain. Each connector operation is delegated
+ * to the bridge closest to the connector (at the end of the chain) that
+ * provides the relevant functionality.
+ *
+ * To make use of this helper, all bridges in the chain shall report bridge
+ * operation flags (&drm_bridge->ops) and bridge output type
+ * (&drm_bridge->type), as well as the DRM_BRIDGE_ATTACH_NO_CONNECTOR attach
+ * flag (none of the bridges shall create a DRM connector directly).

+ * without GuC, so there is no point in trying to fall back.
+ *
+ * Given the above, we can be in one of 4 states, with the last one implying
+ * we're committed to using the microcontroller:
+ * - Not supported: not available in HW and/or firmware not defined.

- * Save all Gunit registers that may be lost after a D3 and a subsequent

- * registers in the following way:
- * - Driver: saved/restored by the driver
- * - Punit : saved/restored by the Punit firmware
- * - No, w/o marking: no need to save/restore, since the register is R/O or
- *                    used internally by the HW in a way that doesn't depend
- *                    keeping the content across a suspend/resume.
- * - Debug : used for debugging
- *
- * We save/restore all registers marked with 'Driver', with the following
- * exceptions:
- * - Registers out of use, including also registers marked with 'Debug'.
- *   These have no effect on the driver's operation, so we don't save/restore
- *   them to reduce the overhead.
- * - Registers that are fully setup by an initialization function called from
- *   the resume path. For example many clock gating and RPS/RC6 registers.
- * - Registers that provide the right functionality with their reset defaults.
- *
- * TODO: Except for registers that based on the above 3 criteria can be safely
- * ignored, we save/restore all others, practically treating the HW context as
- * a black-box for the driver. Further investigation is needed to reduce the
- * saved/restored registers even further, by following the same 3 criteria.

+ * - Driver: saved/restored by the driver
+ * - Punit : saved/restored by the Punit firmware
+ * - No, w/o marking: no need to save/restore, since the register is R/O or
+ *                    used internally by the HW in a way that doesn't depend
+ *                    keeping the content across a suspend/resume.
+ * - Debug : used for debugging
+ *
+ * We save/restore all registers marked with 'Driver', with the following
+ * exceptions:
+ * - Registers out of use, including also registers marked with 'Debug'.
+ *   These have no effect on the driver's operation, so we don't save/restore
+ *   them to reduce the overhead.
+ * - Registers that are fully setup by an initialization function called from
+ *   the resume path. For example many clock gating and RPS/RC6 registers.
+ * - Registers that provide the right functionality with their reset defaults.
+ *
+ * TODO: Except for registers that based on the above 3 criteria can be safely
+ * ignored, we save/restore all others, practically treating the HW context as
+ * a black-box for the driver. Further investigation is needed to reduce the
+ * saved/restored registers even further, by following the same 3 criteria.

+ * On some Intel PCIe bridge controllers doing a
+ * D0 -> D3hot -> D3cold -> D0 sequence causes Nvidia GPUs to not reappear.
+ * Skipping the intermediate D3hot step seems to make it work again. This is
+ * probably caused by not meeting the expectation the involved AML code has
+ * when the GPU is put into D3hot state before invoking it.
+ *
+ * This leads to various manifestations of this issue:
+ *  - AML code execution to power on the GPU hits an infinite loop (as the
+ *    code waits on device memory to change).
+ *  - kernel crashes, as all PCI reads return -1, which most code isn't able
+ *    to handle well enough.
+ *
+ * In all cases dmesg will contain at least one line like this:
+ * 'nouveau 0000:01:00.0: Refused to change power state, currently in D3'
+ * followed by a lot of nouveau timeouts.
+ *
+ * In the \_SB.PCI0.PEG0.PG00._OFF code deeper down writes bit 0x80 to the not
+ * documented PCI config space register 0x248 of the Intel PCIe bridge
+ * controller (0x1901) in order to change the state of the PCIe link between
+ * the PCIe port and the GPU. There are alternative code paths using other
+ * registers, which seem to work fine (executed pre Windows 8):
+ *  - 0xbc bit 0x20 (publicly available documentation claims 'reserved')
+ *  - 0xb0 bit 0x10 (link disable)
+ * Changing the conditions inside the firmware by poking into the relevant
+ * addresses does resolve the issue, but it seemed to be ACPI private memory
+ * and not any device accessible memory at all, so there is no portable way of
+ * changing the conditions.
+ * On a XPS 9560 that means bits [0,3] on \CPEX need to be cleared.
+ *
+ * The only systems where this behavior can be seen are hybrid graphics laptops
+ * with a secondary Nvidia Maxwell, Pascal or Turing GPU. It's unclear whether
+ * this issue only occurs in combination with listed Intel PCIe bridge
+ * controllers and the mentioned GPUs or other devices as well.
+ *
+ * documentation on the PCIe bridge controller can be found in the
+ * "7th Generation Intel® Processor Families for H Platforms Datasheet Volume 2"
+ * Section "12 PCI Express* Controller (x16) Registers"

+ * Copyright (C) 2020 Linus Walleij <linus.walleij@linaro.org>
+ * Based on code by Robert Teather (C) 2012 Samsung
+ *
+ * This display driver (and I refer to the physical component NT35510,
+ * not this Linux kernel software driver) can handle:
+ * 480x864, 480x854, 480x800, 480x720 and 480x640 pixel displays.
+ * It has 480x840x24bit SRAM embedded for storing a frame.
+ * When powered on the display is by default in 480x800 mode.
+ *
+ * The actual panels using this component have different names, but
+ * the code needed to set up and configure the panel will be similar,
+ * so they should all use the NT35510 driver with appropriate configuration
+ * per-panel, e.g. for physical size.
+ *
+ * This driver is for the DSI interface to panels using the NT35510.
+ *
+ * The NT35510 can also use an RGB (DPI) interface combined with an
+ * I2C or SPI interface for setting up the NT35510. If this is needed
+ * this panel driver should be refactored to also support that use
+ * case.

+ *
+ * Some of the settings provide an array of bytes, A, B C which mean:
+ * A = normal / idle off mode
+ * B = idle on mode
+ * C = partial / idle off mode
+ *
+ * Gamma correction arrays are 10bit numbers, two consecutive bytes
+ * makes out one point on the gamma correction curve. The points are
+ * not linearly placed along the X axis, we get points 0, 1, 3, 5
+ * 7, 11, 15, 23, 31, 47, 63, 95, 127, 128, 160, 192, 208, 224, 232,
+ * 240, 244, 248, 250, 252, 254, 255. The voltages tuples form
+ * V0, V1, V3 ... V255, with 0x0000 being the lowest voltage and
+ * 0x03FF being the highest voltage.
+ *
+ * Each value must be strictly higher than the previous value forming
+ * a rising curve like this:
+ *
+ * ^

  * FIFO Synchronization Registers
  *
- *  This explains the relationship between the various FIFO
- *  sync-related registers in IOSpace and in FIFO space.
- *
  *  SVGA_REG_SYNC --
  *
- *       The SYNC register can be used in two different ways by the guest:
- *
- *         1. If the guest wishes to fully sync (drain) the FIFO,
- *            it will write once to SYNC then poll on the BUSY
- *            register. The FIFO is sync'ed once BUSY is zero.
- *
- *         2. If the guest wants to asynchronously wake up the host,
- *            it will write once to SYNC without polling on BUSY.
- *            Ideally it will do this after some new commands have
- *            been placed in the FIFO, and after reading a zero
- *            from SVGA_FIFO_BUSY.
- *
- *       (1) is the original behaviour that SYNC was designed to
- *       support.  Originally, a write to SYNC would implicitly
- *       trigger a read from BUSY. This causes us to synchronously
- *       process the FIFO.
- *
- *       This behaviour has since been changed so that writing SYNC
- *       will *not* implicitly cause a read from BUSY. Instead, it
- *       makes a channel call which asynchronously wakes up the MKS
- *       thread.
- *
- *       New guests can use this new behaviour to implement (2)
- *       efficiently. This lets guests get the host's attention
- *       without waiting for the MKS to poll, which gives us much
- *       better CPU utilization on SMP hosts and on UP hosts while
- *       we're blocked on the host GPU.
- *
- *       Old guests shouldn't notice the behaviour change. SYNC was
- *       never guaranteed to process the entire FIFO, since it was
- *       bounded to a particular number of CPU cycles. Old guests will
- *       still loop on the BUSY register until the FIFO is empty.
- *
- *       Writing to SYNC currently has the following side-effects:
- *
- *         - Sets SVGA_REG_BUSY to TRUE (in the monitor)
- *         - Asynchronously wakes up the MKS thread for FIFO processing
- *         - The value written to SYNC is recorded as a "reason", for
- *           stats purposes.
- *
- *       If SVGA_FIFO_BUSY is available, drivers are advised to only
- *       write to SYNC if SVGA_FIFO_BUSY is FALSE. Drivers should set
- *       SVGA_FIFO_BUSY to TRUE after writing to SYNC. The MKS will
- *       eventually set SVGA_FIFO_BUSY on its own, but this approach
- *       lets the driver avoid sending multiple asynchronous wakeup
- *       messages to the MKS thread.
+ *       The SYNC register can be used by the guest driver to signal to the
+ *       device that the guest driver is waiting for previously submitted
+ *       commands to complete.
+ *
+ *       When the guest driver writes to the SYNC register, the device sets
+ *       the BUSY register to TRUE, and starts processing the submitted commands
+ *       (if it was not already doing so).  When all previously submitted
+ *       commands are finished and the device is idle again, it sets the BUSY
+ *       register back to FALSE.  (If the guest driver submits new commands
+ *       after writing the SYNC register, the new commands are not guaranteed
+ *       to have been procesesd.)
+ *
+ *       When guest drivers are submitting commands using the FIFO, the device
+ *       periodically polls to check for new FIFO commands when idle, which may
+ *       introduce a delay in command processing.  If the guest-driver wants
+ *       the commands to be processed quickly (which it typically does), it
+ *       should write SYNC after each batch of commands is committed to the
+ *       FIFO to immediately wake up the device.  For even better performance,
+ *       the guest can use the SVGA_FIFO_BUSY register to avoid these extra
+ *       SYNC writes if the device is already active, using the technique known
+ *       as "Ringing the Doorbell" (described below).  (Note that command
+ *       buffer submission implicitly wakes up the device, and so doesn't
+ *       suffer from this problem.)
+ *
+ *       The SYNC register can also be used in combination with BUSY to
+ *       synchronously ensure that all SVGA commands are processed (with both
+ *       the FIFO and command-buffers).  To do this, the guest driver should
+ *       write to SYNC, and then loop reading BUSY until BUSY returns FALSE.
+ *       This technique is known as a "Legacy Sync".
  *
  *  SVGA_REG_BUSY --
  *
  *       This register is set to TRUE when SVGA_REG_SYNC is written,
- *       and it reads as FALSE when the FIFO has been completely
- *       drained.
- *
- *       Every read from this register causes us to synchronously
- *       process FIFO commands. There is no guarantee as to how many
- *       commands each read will process.
+ *       and is set back to FALSE when the device has finished processing
+ *       all commands and is idle again.
  *
- *       CPU time spent processing FIFO commands will be billed to
- *       the guest.
+ *       Every read from the BUSY reigster will block for an undefined
+ *       amount of time (normally until the device finishes some interesting
+ *       work unit), or the device is idle.
  *
- *       New drivers should avoid using this register unless they
- *       need to guarantee that the FIFO is completely drained. It
- *       is overkill for performing a sync-to-fence. Older drivers
- *       will use this register for any type of synchronization.
+ *       Guest drivers can also do a partial Legacy Sync to check for some
+ *       particular condition, for instance by stopping early when a fence
+ *       passes before BUSY has been set back to FALSE.  This is particularly
+ *       useful if the guest-driver knows that it is blocked waiting on the
+ *       device, because it will yield CPU time back to the host.
  *
  *  SVGA_FIFO_BUSY --
  *
- *       This register is a fast way for the guest driver to check
- *       whether the FIFO is already being processed. It reads and
- *       writes at normal RAM speeds, with no monitor intervention.
- *
- *       If this register reads as TRUE, the host is guaranteeing that
- *       any new commands written into the FIFO will be noticed before
- *       the MKS goes back to sleep.
+ *       The SVGA_FIFO_BUSY register is a fast way for the guest driver to check
+ *       whether the device is actively processing FIFO commands before writing
+ *       the more expensive SYNC register.
  *
- *       If this register reads as FALSE, no such guarantee can be
- *       made.
+ *       If this register reads as TRUE, the device is actively processing
+ *       FIFO commands.
  *
- *       The guest should use this register to quickly determine
- *       whether or not it needs to wake up the host. If the guest
- *       just wrote a command or group of commands that it would like
- *       the host to begin processing, it should:
+ *       If this register reads as FALSE, the device may not be actively
+ *       processing commands, and the guest driver should try
+ *       "Ringing the Doorbell".
  *
- *         1. Read SVGA_FIFO_BUSY. If it reads as TRUE, no further
- *            action is necessary.
+ *       To Ring the Doorbell, the guest should:
  *
- *         2. Write TRUE to SVGA_FIFO_BUSY. This informs future guest
- *            code that we've already sent a SYNC to the host and we
- *            don't need to send a duplicate.
+ *       1. Have already written their batch of commands into the FIFO.
+ *       2. Check if the SVGA_FIFO_BUSY register is available by reading
+ *          SVGA_FIFO_MIN.
+ *       3. Read SVGA_FIFO_BUSY.  If it reads as TRUE, the device is actively
+ *          processing FIFO commands, and no further action is necessary.
+ *       4. If SVGA_FIFO_BUSY was FALSE, write TRUE to SVGA_REG_SYNC.
  *
- *         3. Write a reason to SVGA_REG_SYNC. This will send an
- *            asynchronous wakeup to the MKS thread.
+ *       For maximum performance, this procedure should be followed after
+ *       every meaningful batch of commands has been written into the FIFO.
+ *       (Normally when the underlying application signals it's finished a
+ *       meaningful work unit by calling Flush.)

+ *
+ * This start-up time can be optimized a bit more, if we start the writes
+ * over I2C after (t4+t6), but before (t4+t5) expires. But then sensor
+ * initialization over I2C may complete before (t4+t5) expires, and we must
+ * ensure that capture is not started before (t4+t5).
+ *
+ * This delay doesn't account for the power supply startup time. If needed,

+	  Say Y here if you want to enable MOST support.
+	  This driver needs at least one additional component to enable the
+	  desired access from userspace (e.g. character devices) and one that
+	  matches the network controller's hardware interface (e.g. USB).
+
+	  To compile this driver as a module, choose M here: the

- * Quad Enable Requirements (QER):
- * - 000b: Device does not have a QE bit. Device detects 1-1-4 and 1-4-4
- *         reads based on instruction. DQ3/HOLD# functions are hold during
- *         instruction phase.
- * - 001b: QE is bit 1 of status register 2. It is set via Write Status with
- *         two data bytes where bit 1 of the second byte is one.
- *         [...]
- *         Writing only one byte to the status register has the side-effect of
- *         clearing status register 2, including the QE bit. The 100b code is
- *         used if writing one byte to the status register does not modify
- *         status register 2.
- * - 010b: QE is bit 6 of status register 1. It is set via Write Status with
- *         one data byte where bit 6 is one.
- *         [...]
- * - 011b: QE is bit 7 of status register 2. It is set via Write status
- *         register 2 instruction 3Eh with one data byte where bit 7 is one.
- *         [...]
- *         The status register 2 is read using instruction 3Fh.
- * - 100b: QE is bit 1 of status register 2. It is set via Write Status with
- *         two data bytes where bit 1 of the second byte is one.
- *         [...]
- *         In contrast to the 001b code, writing one byte to the status
- *         register does not modify status register 2.
- * - 101b: QE is bit 1 of status register 2. Status register 1 is read using
- *         Read Status instruction 05h. Status register2 is read using
- *         instruction 35h. QE is set via Write Status instruction 01h with
- *         two data bytes where bit 1 of the second byte is one.

+ * DOC: The IPA Generic Software Interface
+ *
+ * The generic software interface (GSI) is an integral component of the IPA,
+ * providing a well-defined communication layer between the AP subsystem
+ * and the IPA core.  The modem uses the GSI layer as well.

+ *		-------------
+ *
+ * In the above diagram, the AP and Modem represent "execution environments"
+ * (EEs), which are independent operating environments that use the IPA for
+ * data transfer.
+ *
+ * Each EE uses a set of unidirectional GSI "channels," which allow transfer
+ * of data to or from the IPA.  A channel is implemented as a ring buffer,
+ * with a DRAM-resident array of "transfer elements" (TREs) available to
+ * describe transfers to or from other EEs through the IPA.  A transfer
+ * element can also contain an immediate command, requesting the IPA perform
+ * actions other than data transfer.
+ *
+ * Each TRE refers to a block of data--also located DRAM.  After writing one
+ * or more TREs to a channel, the writer (either the IPA or an EE) writes a
+ * doorbell register to inform the receiving side how many elements have
+ * been written.
+ *
+ * Each channel has a GSI "event ring" associated with it.  An event ring
+ * is implemented very much like a channel ring, but is always directed from
+ * the IPA to an EE.  The IPA notifies an EE (such as the AP) about channel
+ * events by adding an entry to the event ring associated with the channel.
+ * The GSI then writes its doorbell for the event ring, causing the target
+ * EE to be interrupted.  Each entry in an event ring contains a pointer
+ * to the channel TRE whose completion the event represents.
+ *
+ * Each TRE in a channel ring has a set of flags.  One flag indicates whether
+ * the completion of the transfer operation generates an entry (and possibly
+ * an interrupt) in the channel's event ring.  Other flags allow transfer
+ * elements to be chained together, forming a single logical transaction.
+ * TRE flags are used to control whether and when interrupts are generated
+ * to signal completion of channel transfers.
+ *
+ * Elements in channel and event rings are completed (or consumed) strictly
+ * in order.  Completion of one entry implies the completion of all preceding
+ * entries.  A single completion interrupt can therefore communicate the
+ * completion of many transfers.
+ *
+ * Note that all GSI registers are little-endian, which is the assumed
+ * endianness of I/O space accesses.  The accessor functions perform byte
+ * swapping if needed (i.e., for a big endian CPU).

+ *
+ * This function is called whenever we learn that the GSI hardware has filled

+ * first *unfilled* event in the ring (following the last filled one).
+ *
+ * Events are sequential within the event ring, and transactions are
+ * sequential within the transaction pool.
+ *
+ * Note that @index always refers to an element *within* the event ring.

+ * DOC: GSI Registers
+ *
+ * GSI registers are located within the "gsi" address space defined by Device
+ * Tree.  The offset of each register within that space is specified by
+ * symbols defined below.  The GSI address space is mapped to virtual memory
+ * space in gsi_init().  All GSI registers are 32 bits wide.
+ *
+ * Each register type is duplicated for a number of instances of something.
+ * For example, each GSI channel has its own set of registers defining its
+ * configuration.  The offset to a channel's set of registers is computed
+ * based on a "base" offset plus an additional "stride" amount computed
+ * from the channel's ID.  For such registers, the offset is computed by a
+ * function-like macro that takes a parameter used in the computation.
+ *
+ * The offset of a register dependent on execution environment is computed

+/**
+ * DOC: GSI Transactions
+ *
+ * A GSI transaction abstracts the behavior of a GSI channel by representing
+ * everything about a related group of IPA commands in a single structure.
+ * (A "command" in this sense is either a data transfer or an IPA immediate
+ * command.)  Most details of interaction with the GSI hardware are managed
+ * by the GSI transaction core, allowing users to simply describe commands
+ * to be performed.  When a transaction has completed a callback function
+ * (dependent on the type of endpoint associated with the channel) allows
+ * cleanup of resources associated with the transaction.
+ *
+ * To perform a command (or set of them), a user of the GSI transaction
+ * interface allocates a transaction, indicating the number of TREs required
+ * (one per command).  If sufficient TREs are available, they are reserved
+ * for use in the transaction and the allocation succeeds.  This way
+ * exhaustion of the available TREs in a channel ring is detected
+ * as early as possible.  All resources required to complete a transaction
+ * are allocated at transaction allocation time.
+ *
+ * Commands performed as part of a transaction are represented in an array
+ * of Linux scatterlist structures.  This array is allocated with the
+ * transaction, and its entries are initialized using standard scatterlist
+ * functions (such as sg_set_buf() or skb_to_sgvec()).
+ *
+ * Once a transaction's scatterlist structures have been initialized, the
+ * transaction is committed.  The caller is responsible for mapping buffers
+ * for DMA if necessary, and this should be done *before* allocating
+ * the transaction.  Between a successful allocation and commit of a
+ * transaction no errors should occur.
+ *
+ * Committing transfers ownership of the entire transaction to the GSI
+ * transaction core.  The GSI transaction code formats the content of
+ * the scatterlist array into the channel ring buffer and informs the
+ * hardware that new TREs are available to process.
+ *
+ * The last TRE in each transaction is marked to interrupt the AP when the
+ * GSI hardware has completed it.  Because transfers described by TREs are
+ * performed strictly in order, signaling the completion of just the last
+ * TRE in the transaction is sufficient to indicate the full transaction
+ * is complete.
+ *
+ * When a transaction is complete, ipa_gsi_trans_complete() is called by the
+ * GSI code into the IPA layer, allowing it to perform any final cleanup
+ * required before the transaction is freed.

+ * DOC:  IPA Immediate Commands
+ *
+ * The AP command TX endpoint is used to issue immediate commands to the IPA.
+ * An immediate command is generally used to request the IPA do something
+ * other than data transfer to another endpoint.
+ *
+ * Immediate commands are represented by GSI transactions just like other
+ * transfer requests, represented by a single GSI TRE.  Each immediate
+ * command has a well-defined format, having a payload of a known length.
+ * This allows the transfer element's length field to be used to hold an
+ * immediate command's opcode.  The payload for a command resides in DRAM
+ * and is described by a single scatterlist entry in its transaction.
+ * Commands do not require a transaction completion callback.  To commit
+ * an immediate command transaction, either gsi_trans_commit_wait() or
+ * gsi_trans_commit_wait_timeout() is used.

+/**
+ * DOC: IPA/GSI Configuration Data
+ *
+ * Boot-time configuration data is used to define the configuration of the
+ * IPA and GSI resources to use for a given platform.  This data is supplied
+ * via the Device Tree match table, associated with a particular compatible
+ * string.  The data defines information about resources, endpoints, and
+ * channels.
+ *
+ * Resources are data structures used internally by the IPA hardware.  The
+ * configuration data defines the number (or limits of the number) of various
+ * types of these resources.
+ *
+ * Endpoint configuration data defines properties of both IPA endpoints and
+ * GSI channels.  A channel is a GSI construct, and represents a single
+ * communication path between the IPA and a particular execution environment
+ * (EE), such as the AP or Modem.  Each EE has a set of channels associated
+ * with it, and each channel has an ID unique for that EE.  For the most part
+ * the only GSI channels of concern to this driver belong to the AP
+ *
+ * An endpoint is an IPA construct representing a single channel anywhere
+ * in the system.  An IPA endpoint ID maps directly to an (EE, channel_id)
+ * pair.  Generally, this driver is concerned with only endpoints associated
+ * with the AP, however this will change when support for routing (etc.) is
+ * added.  IPA endpoint and GSI channel configuration data are defined
+ * together, establishing the endpoint_id->(EE, channel_id) mapping.
+ *
+ * Endpoint configuration data consists of three parts:  properties that
+ * are common to IPA and GSI (EE ID, channel ID, endpoint ID, and direction);
+ * properties associated with the GSI channel; and properties associated with
+ * the IPA endpoint.

+ *
+ * A GSI channel is a unidirectional means of transferring data to or
+ * from (and through) the IPA.  A GSI channel has a ring buffer made
+ * up of "transfer elements" (TREs) that specify individual data transfers
+ * or IPA immediate commands.  TREs are filled by the AP, and control
+ * is passed to IPA hardware by writing the last written element
+ * into a doorbell register.
+ *
+ * When data transfer commands have completed the GSI generates an
+ * event (a structure of data) and optionally signals the AP with
+ * an interrupt.  Event structures are implemented by another ring
+ * buffer, directed toward the AP from the IPA.
+ *
+ * The input to a GSI channel is a FIFO of type/length/value (TLV)
+ * elements, and the size of this FIFO limits the number of TREs
+ * that can be included in a single transaction.

+/**
+ * DOC: The IP Accelerator
+ *
+ * This driver supports the Qualcomm IP Accelerator (IPA), which is a
+ * networking component found in many Qualcomm SoCs.  The IPA is connected
+ * to the application processor (AP), but is also connected (and partially
+ * controlled by) other "execution environments" (EEs), such as a modem.
+ *
+ * The IPA is the conduit between the AP and the modem that carries network
+ * traffic.  This driver presents a network interface representing the
+ * connection of the modem to external (e.g. LTE) networks.
+ *
+ * The IPA provides protocol checksum calculation, offloading this work
+ * from the AP.  The IPA offers additional functionality, including routing,
+ * filtering, and NAT support, but that more advanced functionality is not
+ * currently supported.  Despite that, some resources--including routing
+ * tables and filter tables--are defined in this driver because they must
+ * be initialized even when the advanced hardware features are not used.
+ *
+ * There are two distinct layers that implement the IPA hardware, and this
+ * is reflected in the organization of the driver.  The generic software
+ * interface (GSI) is an integral component of the IPA, providing a
+ * well-defined communication layer between the AP subsystem and the IPA
+ * core.  The GSI implements a set of "channels" used for communication
+ * between the AP and the IPA.
+ *
+ * The IPA layer uses GSI channels to implement its "endpoints".  And while
+ * a GSI channel carries data between the AP and the IPA, a pair of IPA
+ * endpoints is used to carry traffic between two EEs.  Specifically, the main
+ * modem network interface is implemented by two pairs of endpoints:  a TX
+ * endpoint on the AP coupled with an RX endpoint on the modem; and another
+ * RX endpoint on the AP receiving data from a TX endpoint on the modem.

+ *
+ * The IPA has a block of shared memory, divided into regions used for
+ * specific purposes.
+ *
+ * The regions within the shared block are bounded by an offset (relative to
+ * the "ipa-shared" memory range) and size found in the IPA_SHARED_MEM_SIZE
+ * register.
+ *
+ * Each region is optionally preceded by one or more 32-bit "canary" values.
+ * These are meant to detect out-of-range writes (if they become corrupted).
+ * A given region (such as a filter or routing table) has the same number
+ * of canaries for all IPA hardware versions.  Still, the number used is
+ * defined in the config data, allowing for generic handling of regions.
+ *
+ * The set of memory regions is defined in configuration data.  They are
+ * subject to these constraints:
+ * - a zero offset and zero size represents and undefined region
+ * - a region's offset is defined to be *past* all "canary" values
+ * - offset must be large enough to account for all canaries
+ * - a region's size may be zero, but may still have canaries
+ * - all offsets must be 8-byte aligned
+ * - most sizes must be a multiple of 8
+ * - modem memory size must be a multiple of 4
+ * - the microcontroller ring offset must be a multiple of 1024

+/**
+ * DOC: AP/Modem QMI Handshake
+ *
+ * The AP and modem perform a "handshake" at initialization time to ensure
+ * both sides know when everything is ready to begin operating.  The AP
+ * driver (this code) uses two QMI handles (endpoints) for this; a client
+ * using a service on the modem, and server to service modem requests (and
+ * to supply an indication message from the AP).  Once the handshake is
+ * complete, the AP and modem may begin IPA operation.  This occurs
+ * only when the AP IPA driver, modem IPA driver, and IPA microcontroller
+ * are ready.
+ *
+ * The QMI service on the modem expects to receive an INIT_DRIVER request from
+ * the AP, which contains parameters used by the modem during initialization.
+ * The AP sends this request as soon as it is knows the modem side service
+ * is available.  The modem responds to this request, and if this response
+ * contains a success result, the AP knows the modem IPA driver is ready.
+ *
+ * The modem is responsible for loading firmware on the IPA microcontroller.
+ * This occurs only during the initial modem boot.  The modem sends a
+ * separate DRIVER_INIT_COMPLETE request to the AP to report that the
+ * microcontroller is ready.  The AP may assume the microcontroller is
+ * ready and remain so (even if the modem reboots) once it has received
+ * and responded to this request.
+ *
+ * There is one final exchange involved in the handshake.  It is required
+ * on the initial modem boot, but optional (but in practice does occur) on
+ * subsequent boots.  The modem expects to receive a final INIT_COMPLETE
+ * indication message from the AP when it is about to begin its normal
+ * operation.  The AP will only send this message after it has received
+ * and responded to an INDICATION_REGISTER request from the modem.
+ *
+ * So in summary:
+ * - Whenever the AP learns the modem has booted and its IPA QMI service
+ *   is available, it sends an INIT_DRIVER request to the modem.  The
+ *   modem supplies a success response when it is ready to operate.
+ * - On the initial boot, the modem sets up the IPA microcontroller, and
+ *   sends a DRIVER_INIT_COMPLETE request to the AP when this is done.
+ * - When the modem is ready to receive an INIT_COMPLETE indication from
+ *   the AP, it sends an INDICATION_REGISTER request to the AP.
+ * - On the initial modem boot, everything is ready when:
+ *	- AP has received a success response from its INIT_DRIVER request
+ *	- AP has responded to a DRIVER_INIT_COMPLETE request
+ *	- AP has responded to an INDICATION_REGISTER request from the modem
+ *	- AP has sent an INIT_COMPLETE indication to the modem
+ * - On subsequent modem boots, everything is ready when:
+ *	- AP has received a success response from its INIT_DRIVER request
+ *	- AP has responded to a DRIVER_INIT_COMPLETE request
+ * - The INDICATION_REGISTER request and INIT_COMPLETE indication are
+ *   optional for non-initial modem boots, and have no bearing on the
+ *   determination of when things are "ready"

+/**
+ * DOC: IPA Registers
+ *
+ * IPA registers are located within the "ipa-reg" address space defined by
+ * Device Tree.  The offset of each register within that space is specified
+ * by symbols defined below.  The address space is mapped to virtual memory
+ * space in ipa_mem_init().  All IPA registers are 32 bits wide.
+ *
+ * Certain register types are duplicated for a number of instances of
+ * something.  For example, each IPA endpoint has an set of registers
+ * defining its configuration.  The offset to an endpoint's set of registers
+ * is computed based on an "base" offset, plus an endpoint's ID multiplied
+ * and a "stride" value for the register.  For such registers, the offset is
+ * computed by a function-like macro that takes a parameter used in the
+ * computation.
+ *
+ * Some register offsets depend on execution environment.  For these an "ee"
+ * parameter is supplied to the offset macro.  The "ee" value is a member of
+ * the gsi_ee enumerated type.
+ *
+ * The offset of a register dependent on endpoint id is computed by a macro
+ * that is supplied a parameter "ep".  The "ep" value is assumed to be less
+ * than the maximum endpoint value for the current hardware, and that will
+ * not exceed IPA_ENDPOINT_MAX.
+ *
+ * The offset of registers related to filter and route tables is computed
+ * by a macro that is supplied a parameter "er".  The "er" represents an
+ * endpoint ID for filters, or a route ID for routes.  For filters, the
+ * endpoint ID must be less than IPA_ENDPOINT_MAX, but is further restricted
+ * because not all endpoints support filtering.  For routes, the route ID
+ * must be less than IPA_ROUTE_MAX.
+ *
+ * The offset of registers related to resource types is computed by a macro
+ * that is supplied a parameter "rt".  The "rt" represents a resource type,
+ * which is is a member of the ipa_resource_type_src enumerated type for
+ * source endpoint resources or the ipa_resource_type_dst enumerated type
+ * for destination endpoint resources.
+ *
+ * Some registers encode multiple fields within them.  For these, each field
+ * has a symbol below defining a field mask that encodes both the position
+ * and width of the field within its register.
+ *
+ * In some cases, different versions of IPA hardware use different offset or
+ * field mask values.  In such cases an inline_function(ipa) is used rather
+ * than a MACRO to define the offset or field mask to use.
+ *
+ * Finally, some registers hold bitmasks representing endpoints.  In such
+ * cases the @available field in the @ipa structure defines the "full" set
+ * of valid bits for the register.

+/**
+ * DOC: IPA SMP2P communication with the modem
+ *
+ * SMP2P is a primitive communication mechanism available between the AP and
+ * the modem.  The IPA driver uses this for two purposes:  to enable the modem
+ * to state that the GSI hardware is ready to use; and to communicate the
+ * state of the IPA clock in the event of a crash.
+ *
+ * GSI needs to have early initialization completed before it can be used.
+ * This initialization is done either by Trust Zone or by the modem.  In the
+ * latter case, the modem uses an SMP2P interrupt to tell the AP IPA driver
+ * when the GSI is ready to use.
+ *
+ * The modem is also able to inquire about the current state of the IPA
+ * clock by trigging another SMP2P interrupt to the AP.  We communicate
+ * whether the clock is enabled using two SMP2P state bits--one to
+ * indicate the clock state (on or off), and a second to indicate the
+ * clock state bit is valid.  The modem will poll the valid bit until it
+ * is set, and at that time records whether the AP has the IPA clock enabled.
+ *
+ * Finally, if the AP kernel panics, we update the SMP2P state bits even if
+ * we never receive an interrupt from the modem requesting this.

+/**
+ * DOC: IPA Filter and Route Tables
+ *
+ * The IPA has tables defined in its local shared memory that define filter
+ * and routing rules.  Each entry in these tables contains a 64-bit DMA
+ * address that refers to DRAM (system memory) containing a rule definition.
+ * A rule consists of a contiguous block of 32-bit values terminated with
+ * 32 zero bits.  A special "zero entry" rule consisting of 64 zero bits
+ * represents "no filtering" or "no routing," and is the reset value for
+ * filter or route table rules.  Separate tables (both filter and route)
+ * used for IPv4 and IPv6.  Additionally, there can be hashed filter or
+ * route tables, which are used when a hash of message metadata matches.
+ * Hashed operation is not supported by all IPA hardware.
+ *
+ * Each filter rule is associated with an AP or modem TX endpoint, though
+ * not all TX endpoints support filtering.  The first 64-bit entry in a
+ * filter table is a bitmap indicating which endpoints have entries in
+ * the table.  The low-order bit (bit 0) in this bitmap represents a
+ * special global filter, which applies to all traffic.  This is not
+ * used in the current code.  Bit 1, if set, indicates that there is an
+ * entry (i.e. a DMA address referring to a rule) for endpoint 0 in the
+ * table.  Bit 2, if set, indicates there is an entry for endpoint 1,
+ * and so on.  Space is set aside in IPA local memory to hold as many
+ * filter table entries as might be required, but typically they are not
+ * all used.
+ *
+ * The AP initializes all entries in a filter table to refer to a "zero"
+ * entry.  Once initialized the modem and AP update the entries for
+ * endpoints they "own" directly.  Currently the AP does not use the
+ * IPA filtering functionality.
+ *

+ * The set of available route rules is divided about equally between the AP

+ * DOC:  The IPA embedded microcontroller
+ *
+ * The IPA incorporates a microcontroller that is able to do some additional
+ * handling/offloading of network activity.  The current code makes
+ * essentially no use of the microcontroller, but it still requires some
+ * initialization.  It needs to be notified in the event the AP crashes.
+ *
+ * The microcontroller can generate two interrupts to the AP.  One interrupt
+ * is used to indicate that a response to a request from the AP is available.
+ * The other is used to notify the AP of the occurrence of an event.  In
+ * addition, the AP can interrupt the microcontroller by writing a register.
+ *
+ * A 128 byte block of structured memory within the IPA SRAM is used together
+ * with these interrupts to implement the communication interface between the
+ * AP and the IPA microcontroller.  Each side writes data to the shared area
+ * before interrupting its peer, which will read the written data in response
+ * to the interrupt.  Some information found in the shared area is currently
+ * unused.  All remaining space in the shared area is reserved, and must not
+ * be read or written by the AP.
+ */

+ * @rx: boolean from ethtool struct ethtool_pauseparam rx_pause member
+ *
+ * Configure the advertised Pause and Asym_Pause bits according to the
+ * capabilities of provided in @tx and @rx.
+ *
+ * We convert as follows:
+ *  tx rx  Pause AsymDir
+ *  0  0   0     0
+ *  0  1   1     1
+ *  1  0   0     1
+ *  1  1   1     0
+ *
+ * Note: this translation from ethtool tx/rx notation to the advertisement
+ * is actually very problematical. Here are some examples:
+ *
+ * For tx=0 rx=1, meaning transmit is unsupported, receive is supported:
+ *
+ *  Local device  Link partner
+ *  Pause AsymDir Pause AsymDir Result
+ *    1     1       1     0     TX + RX - but we have no TX support.
+ *    1     1       0     1	Only this gives RX only
+ *
+ * For tx=1 rx=1, meaning we have the capability to transmit and receive
+ * pause frames:
+ *
+ *  Local device  Link partner
+ *  Pause AsymDir Pause AsymDir Result
+ *    1     0       0     1     Disabled - but since we do support tx and rx,
+ *				this should resolve to RX only.
+ *
+ * Hence, asking for:
+ *  rx=1 tx=0 gives Pause+AsymDir advertisement, but we may end up
+ *            resolving to tx+rx pause or only rx pause depending on
+ *            the partners advertisement.
+ *  rx=0 tx=1 gives AsymDir only, which will only give tx pause if
+ *            the partners advertisement allows it.
+ *  rx=1 tx=1 gives Pause only, which will only allow tx+rx pause
+ *            if the other end also advertises Pause.

+ * &electric_1/motor-1/electric and &spin_ctrl_1/electric are the same node:

  *
  * Thus the property "rpm_avail" in each fragment will

  * This will result in an error and the overlay apply
  * will fail.
+ *
+ * The previous version of this test did not include the extra
+ * level of node 'electric'.  That resulted in the 'rpm_avail'
+ * property being located in the pre-existing node 'motor-1'.
+ * Modifying a property results in a WARNING that a memory leak
+ * will occur if the overlay is removed.  Since the overlay apply
+ * fails, the memory leak does actually occur, and kmemleak will
+ * further report the memory leak if CONFIG_DEBUG_KMEMLEAK is
+ * enabled.  Adding the overlay node 'electric' avoids the
+ * memory leak and thus people who use kmemleak will not
+ * have to debug this non-problem again.

+ *   a - EC timebase, sensor event
+ *   b - EC timebase, IRQ
+ *   c - AP timebase, IRQ
+ *   a' - what we want: sensor even in AP timebase
+ *
+ * While a and b are recorded at accurate times (due to the EC real time
+ * nature); c is pretty untrustworthy, even though it's recorded the
+ * first thing in ec_irq_handler(). There is a very good change we'll get
+ * added lantency due to:
+ *   other irqs
+ *   ddrfreq
+ *   cpuidle
+ *
+ * Normally a' = c - b + a, but if we do that naive math any jitter in c
+ * will get coupled in a', which we don't want. We want a function
+ * a' = cros_ec_sensor_ring_ts_filter(a) which will filter out outliers in c.
+ *
+ * Think of a graph of AP time(b) on the y axis vs EC time(c) on the x axis.
+ * The slope of the line won't be exactly 1, there will be some clock drift
+ * between the 2 chips for various reasons (mechanical stress, temperature,
+ * voltage). We need to extrapolate values for a future x, without trusting
+ * recent y values too much.
+ *
+ * We use a median filter for the slope, then another median filter for the
+ * y-intercept to calculate this function:
+ *   dx[n] = x[n-1] - x[n]
+ *   dy[n] = x[n-1] - x[n]
+ *   m[n] = dy[n] / dx[n]
+ *   median_m = median(m[n-k:n])
+ *   error[i] = y[n-i] - median_m * x[n-i]
+ *   median_error = median(error[:k])
+ *   predicted_y = median_m * x + median_error
+ *
+ * Implementation differences from above:
+ * - Redefined y to be actually c - b, this gives us a lot more precision
+ * to do the math. (c-b)/b variations are more obvious than c/b variations.
+ * - Since we don't have floating point, any operations involving slope are
+ * done using fixed point math (*M_PRECISION)
+ * - Since x and y grow with time, we keep zeroing the graph (relative to
+ * the last sample), this way math involving *x[n-i] will not overflow
+ * - EC timestamps are kept in us, it improves the slope calculation precision

+
+	  The implementation of this in Linux currently only exposes this to

+ * This driver has been reverse-engineered by parsing the DSDT of the Surface 3
+ * and looking at the registers of the chips.
+ *
+ * The DSDT allowed to find out that:
+ * - the driver is required for the ACPI BAT0 device to communicate to the chip
+ *   through an operation region.
+ * - the various defines for the operation region functions to communicate with
+ *   this driver
+ * - the DSM 3f99e367-6220-4955-8b0f-06ef2ae79412 allows to trigger ACPI
+ *   events to BAT0 (the code is all available in the DSDT).
+ *
+ * Further findings regarding the 2 chips declared in the MSHW0011 are:
+ * - there are 2 chips declared:
+ *   . 0x22 seems to control the ADP1 line status (and probably the charger)
+ *   . 0x55 controls the battery directly
+ * - the battery chip uses a SMBus protocol (using plain SMBus allows non
+ *   destructive commands):
+ *   . the commands/registers used are in the range 0x00..0x7F
+ *   . if bit 8 (0x80) is set in the SMBus command, the returned value is the
+ *     same as when it is not set. There is a high chance this bit is the
+ *     read/write
+ *   . the various registers semantic as been deduced by observing the register
+ *     dumps.

+ * Cherry Trail SoC + TI PMIC,     DMI_BOARD_NAME: "827C" or "82F4"
+ *
+ * The variants with the AXP288 PMIC are all kinds of special:
+ *
+ * 1. All variants use a Type-C connector which the AXP288 does not support, so
+ * when using a Type-C charger it is not recognized. Unlike most AXP288 devices,
+ * this model actually has mostly working ACPI AC / Battery code, the ACPI code
+ * "solves" this by simply setting the input_current_limit to 3A.
+ * There are still some issues with the ACPI code, so we use this native driver,
+ * and to solve the charging not working (500mA is not enough) issue we hardcode
+ * the 3A input_current_limit like the ACPI code does.
+ *
+ * 2. If no charger is connected the machine boots with the vbus-path disabled.
+ * Normally this is done when a 5V boost converter is active to avoid the PMIC
+ * trying to charge from the 5V boost converter's output. This is done when
+ * an OTG host cable is inserted and the ID pin on the micro-B receptacle is
+ * pulled low and the ID pin has an ACPI event handler associated with it
+ * which re-enables the vbus-path when the ID pin is pulled high when the
+ * OTG host cable is removed. The Type-C connector has no ID pin, there is
+ * no ID pin handler and there appears to be no 5V boost converter, so we
+ * end up not charging because the vbus-path is disabled, until we unplug
+ * the charger which automatically clears the vbus-path disable bit and then
+ * on the second plug-in of the adapter we start charging. To solve the not
+ * charging on first charger plugin we unconditionally enable the vbus-path at
+ * probe on this model, which is safe since there is no 5V boost converter.

  * Description:
  *   This file is the core OMAP support for the generic, Linux
- *   PWM driver / controller, using the OMAP's dual-mode timers.
+ *   PWM driver / controller, using the OMAP's dual-mode timers
+ *   with a timer counter that goes up. When it overflows it gets
+ *   reloaded with the load value and the pwm output goes up.
+ *   When counter matches with match register, the output goes down.
+ *   Reference Manual: http://www.ti.com/lit/ug/spruh73q/spruh73q.pdf
+ *
+ * Limitations:
+ * - When PWM is stopped, timer counter gets stopped immediately. This
+ *   doesn't allow the current PWM period to complete and stops abruptly.
+ * - When PWM is running and changing both duty cycle and period,
+ *   we cannot prevent in software that the output might produce
+ *   a period with mixed settings. Especially when period/duty_cyle
+ *   is updated while the pwm pin is high, current pwm period/duty_cycle
+ *   can get updated as below based on the current timer counter:
+ *   	- period for current cycle =  current_period + new period
+ *   	- duty_cycle for current period = current period + new duty_cycle.
+ * - PWM OMAP DM timer cannot change the polarity when pwm is active. When
+ *   user requests a change in polarity when in active state:
+ *	- PWM is stopped abruptly(without completing the current cycle)
+ *	- Polarity is changed
+ *	- A fresh cycle is started.

-A laundry list of things that need looking at, most of which will
-require more work than the average checkpatch cleanup...
-
-Note that some of these entries may not be bugs - they're things
-that need to be looked at, and *possibly* fixed.
-
-Clean up the ffsCamelCase function names.
-
-Fix (thing)->flags to not use magic numbers - multiple offenders
-
-Sort out all the s32/u32/u8 nonsense - most of these should be plain int.
-
-exfat_core.c - ffsReadFile - the goto err_out seem to leak a brelse().
-same for ffsWriteFile.
-
-All the calls to fs_sync() need to be looked at, particularly in the
-context of EXFAT_DELAYED_SYNC. Currently, if that's defined, we only
-flush to disk when sync() gets called.  We should be doing at least
-metadata flushes at appropriate times.
-
-ffsTruncateFile -  if (old_size <= new_size) {
-That doesn't look right. How did it ever work? Are they relying on lazy
-block allocation when actual writes happen? If nothing else, it never
-does the 'fid->size = new_size' and do the inode update....
-
-ffsSetAttr() is just dangling in the breeze, not wired up at all...
-
-Convert global mutexes to a per-superblock mutex.
-
-Right now, we load exactly one UTF-8 table. Check to see
-if that plays nice with different codepage and iocharset values
-for simultanous mounts of different devices
-
-exfat_rmdir() checks for -EBUSY but ffsRemoveDir() doesn't return it.
-In fact, there's a complete lack of -EBUSY testing anywhere.
-
-There's probably a few missing checks for -EEXIST
-
-check return codes of sync_dirty_buffer()
-
-Why is remove_file doing a num_entries++??
-
-Double check a lot of can't-happen parameter checks (for null pointers for
-things that have only one call site and can't pass a null, etc).
-
-All the DEBUG stuff can probably be tossed, including the ioctl(). Either
-that, or convert to a proper fault-injection system.
-
-exfat_remount does exactly one thing.  Fix to actually deal with remount
-options, particularly handling R/O correctly.  For that matter, allow
-R/O mounts in the first place.
-
-Figure out why the VFAT code used multi_sector_(read|write) but the
-exfat code doesn't use it. The difference matters on SSDs with wear leveling.
-
-exfat_fat_sync(), exfat_buf_sync(), and sync_alloc_bitmap()
-aren't called anyplace....
-
-Create helper function for exfat_set_entry_time() and exfat_set_entry_type()
-because it's sort of ugly to be calling the same functionn directly and
-other code calling through the fs_func struc ponters...
-
-clean up the remaining vol_type checks, which are of two types:
-some are ?: operators with magic numbers, and the rest are places
-where we're doing stuff with '.' and '..'.

-** hp100.c
-** HP CASCADE Architecture Driver for 100VG-AnyLan Network Adapters
-**
-** $Id: hp100.c,v 1.58 2001/09/24 18:03:01 perex Exp perex $
-**
-** Based on the HP100 driver written by Jaroslav Kysela <perex@jcu.cz>
-** Extended for new busmaster capable chipsets by
-** Siegfried "Frieder" Loeffler (dg1sek) <floeff@mathematik.uni-stuttgart.de>
-**
-** Maintained by: Jaroslav Kysela <perex@perex.cz>
-**
-** This driver has only been tested with
-** -- HP J2585B 10/100 Mbit/s PCI Busmaster
-** -- HP J2585A 10/100 Mbit/s PCI
-** -- HP J2970A 10 Mbit/s PCI Combo 10base-T/BNC
-** -- HP J2973A 10 Mbit/s PCI 10base-T
-** -- HP J2573  10/100 ISA
-** -- Compex ReadyLink ENET100-VG4  10/100 Mbit/s PCI / EISA
-** -- Compex FreedomLine 100/VG  10/100 Mbit/s ISA / EISA / PCI
-**
-** but it should also work with the other CASCADE based adapters.
-**
-** TODO:
-**       -  J2573 seems to hang sometimes when in shared memory mode.
-**       -  Mode for Priority TX
-**       -  Check PCI registers, performance might be improved?
-**       -  To reduce interrupt load in busmaster, one could switch off
-**          the interrupts that are used to refill the queues whenever the
-**          queues are filled up to more than a certain threshold.
-**       -  some updates for EISA version of card
-**
-**
-**
-** 1.57c -> 1.58
-**   - used indent to change coding-style
-**   - added KTI DP-200 EISA ID
-**   - ioremap is also used for low (<1MB) memory (multi-architecture support)
-**
-** 1.57b -> 1.57c - Arnaldo Carvalho de Melo <acme@conectiva.com.br>
-**   - release resources on failure in init_module
-**
-** 1.57 -> 1.57b - Jean II
-**   - fix spinlocks, SMP is now working !
-**
-** 1.56 -> 1.57
-**   - updates for new PCI interface for 2.1 kernels
-**
-** 1.55 -> 1.56
-**   - removed printk in misc. interrupt and update statistics to allow
-**     monitoring of card status
-**   - timing changes in xmit routines, relogin to 100VG hub added when
-**     driver does reset
-**   - included fix for Compex FreedomLine PCI adapter
-**
-** 1.54 -> 1.55
-**   - fixed bad initialization in init_module
-**   - added Compex FreedomLine adapter
-**   - some fixes in card initialization
-**
-** 1.53 -> 1.54
-**   - added hardware multicast filter support (doesn't work)
-**   - little changes in hp100_sense_lan routine
-**     - added support for Coax and AUI (J2970)
-**   - fix for multiple cards and hp100_mode parameter (insmod)
-**   - fix for shared IRQ
-**
-** 1.52 -> 1.53
-**   - fixed bug in multicast support

-		In bridge applications, such as strain gauges and load cells,
-		the bridge itself consumes the majority of the current in the

-		the bridge can be disconnected (when it is not being used
-		using the bridge_switch_en attribute.

+The driver is deprecated and scheduled for removal by the end

+In order to prevent removal the following actions would have to
+be taken:
+
+- clean up the code
+- convert to the vb2 framework
+- fix the disconnect and free-on-last-user handling (i.e., add
+  a release callback for struct v4l2_device and rework the code
