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
