Distribution
============
Along with the interface definitions, the following drivers, state trackers,
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 :ref:`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 a2xx, a3xx, and a4xx series of GPUs.
.. _softpipe:
Softpipe
^^^^^^^^
Reference software rasterizer. Slow but accurate.
.. _trace:
Trace
^^^^^
Wrapper driver. Trace dumps an XML record of the calls made to the
:ref:`Context` and :ref:`Screen` objects that it wraps.
Rbug
^^^^
Wrapper driver. :ref:`rbug` driver used with stand alone rbug-gui.
State Trackers
--------------
Clover
^^^^^^
Tracker that implements the Khronos OpenCL standard.
.. _dri:
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
^^^^^^
Tracker implementing a GL state machine. Not usable as a standalone tracker;
Mesa should be built with another state tracker, such as :ref:`DRI` or
:ref:`EGL`.
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.
XvMC
^^^^
Tracker for X-Video Motion Compensation.
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
^^^^
Draw is a software :term:`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
^^^^
