Distribution — The Mesa 3D Graphics Library latest documentation

# Distribution

Along with the interface definitions, the following drivers, Gallium frontends, and auxiliary modules are shipped in the standard Gallium distribution.

## Drivers

### Intel i915

Driver for Intel i915 and i945 chipsets.

### LLVM Softpipe

A version of Softpipe that uses the Low-Level Virtual Machine to dynamically generate optimized rasterizing pipelines.

### NVIDIA NV30

Driver for the NVIDIA NV30 and NV40 families of GPUs.

### NVIDIA NV50

Driver for the NVIDIA NV50 family of GPUs.

### NVIDIA NVC0

Driver for the NVIDIA NVC0 / Fermi family of GPUs.

### VMware SVGA

Driver for VMware virtualized guest operating system graphics processing.

### ATI R300

Driver for the ATI/AMD R300, R400, and R500 families of GPUs.

### ATI/AMD R600

Driver for the ATI/AMD R600, R700, Evergreen and Northern Islands families of GPUs.

### AMD RadeonSI

Driver for the AMD Southern Islands family of GPUs.

### Freedreno

Driver for Qualcomm Adreno 2xx, 3xx, and 4xx series of GPUs.

### Softpipe

Reference software rasterizer. Slow but accurate.

### Trace

Wrapper driver. Trace dumps an XML record of the calls made to the Context and Screen objects that it wraps.

## Gallium frontends

### Clover

Tracker that implements the Khronos OpenCL standard.

### Direct Rendering Infrastructure

Tracker that implements the client-side DRI protocol, for providing direct acceleration services to X11 servers with the DRI extension. Supports DRI1 and DRI2. Only GL is supported.

### GLX

### MesaGL

The Gallium frontend implementing a GL state machine. Not usable as a standalone frontend; Mesa should be built with another Gallium frontend, such as Direct Rendering Infrastructure or EGL.

### Nine

The Gallium frontend implements the Direct3D 9 API.

### VDPAU

Tracker for Video Decode and Presentation API for Unix.

### WGL

### Xorg DDX

Tracker for Xorg X11 servers. Provides device-dependent modesetting and acceleration as a DDX driver.

## Auxiliary

### OS

The OS module contains the abstractions for basic operating system services:

- memory allocation

- simple message logging

- obtaining run-time configuration option

- threading primitives

This is the bare minimum required to port Gallium to a new platform.

The OS module already provides the implementations of these abstractions for the most common platforms. When targeting an embedded platform no implementation will be provided – these must be provided separately.

### CSO Cache

The CSO cache is used to accelerate preparation of state by saving driver-specific state structures for later use.

### Draw

Draw is a software TCL pipeline for hardware that lacks vertex shaders or other essential parts of pre-rasterization vertex preparation.

### Gallivm

### Indices

Indices provides tools for translating or generating element indices for use with element-based rendering.

### Pipe Buffer Managers

Each of these managers provides various services to drivers that are not fully utilizing a memory manager.

### Remote Debugger

### Runtime Assembly Emission

### TGSI

The TGSI auxiliary module provides basic utilities for manipulating TGSI streams.

### Translate

### Util
