   1 Distribution
   2 ============
   3
   4 Along with the interface definitions, the following drivers, state trackers,
   5 and auxiliary modules are shipped in the standard Gallium distribution.
   6
   7 Drivers
   8 -------
   9
  10 Intel i915
  11 ^^^^^^^^^^
  12
  13 Driver for Intel i915 and i945 chipsets.
  14
  15 Identity
  16 ^^^^^^^^
  17
  18 Wrapper driver. The identity driver is a simple skeleton that passes through
  19 all of its :ref:`Context` and :ref:`Screen` methods to an underlying Context
  20 and Screen, and as such, it is an excellent starting point for new drivers.
  21
  22 LLVM Softpipe
  23 ^^^^^^^^^^^^^
  24
  25 A version of :ref:`softpipe` that uses the Low-Level Virtual Machine to
  26 dynamically generate optimized rasterizing pipelines.
  27
  28 nVidia nv30
  29 ^^^^^^^^^^^
  30
  31 Driver for the nVidia nv30 and nv40 families of GPUs.
  32
  33 nVidia nv50
  34 ^^^^^^^^^^^
  35
  36 Driver for the nVidia nv50 family of GPUs.
  37
  38 nVidia nvc0
  39 ^^^^^^^^^^^
  40
  41 Driver for the nVidia nvc0 / fermi family of GPUs.
  42
  43 VMware SVGA
  44 ^^^^^^^^^^^
  45
  46 Driver for VMware virtualized guest operating system graphics processing.
  47
  48 ATI r300
  49 ^^^^^^^^
  50
  51 Driver for the ATI/AMD r300, r400, and r500 families of GPUs.
  52
  53 ATI/AMD r600
  54 ^^^^^^^^^^^^
  55
  56 Driver for the ATI/AMD r600, r700, Evergreen and Northern Islands families of GPUs.
  57
  58 AMD radeonsi
  59 ^^^^^^^^^^^^
  60
  61 Driver for the AMD Southern Islands family of GPUs.
  62
  63 .. _softpipe:
  64
  65 Softpipe
  66 ^^^^^^^^
  67
  68 Reference software rasterizer. Slow but accurate.
  69
  70 .. _trace:
  71
  72 Trace
  73 ^^^^^
  74
  75 Wrapper driver. Trace dumps an XML record of the calls made to the
  76 :ref:`Context` and :ref:`Screen` objects that it wraps.
  77
  78 Rbug
  79 ^^^^
  80
  81 Wrapper driver. :ref:`rbug` driver used with stand alone rbug-gui.
  82
  83 .. _galahad:
  84
  85 Galahad
  86 ^^^^^^^
  87
  88 Wrapper driver. Sanity checker for the internal gallium state. Normally
  89 a driver should n't have to sanity check the input it gets from a state
  90 tracker. Any wrong state received should be perceived as a state tracker bug.
  91
  92 State Trackers
  93 --------------
  94
  95 Clover
  96 ^^^^^^
  97
  98 Tracker that implements the Khronos OpenCL standard.
  99
 100 .. _dri:
 101
 102 Direct Rendering Infrastructure
 103 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
 104
 105 Tracker that implements the client-side DRI protocol, for providing direct
 106 acceleration services to X11 servers with the DRI extension. Supports DRI1
 107 and DRI2. Only GL is supported.
 108
 109 GLX
 110 ^^^
 111
 112 MesaGL
 113 ^^^^^^
 114
 115 Tracker implementing a GL state machine. Not usable as a standalone tracker;
 116 Mesa should be built with another state tracker, such as :ref:`DRI` or
 117 :ref:`EGL`.
 118
 119 VDPAU
 120 ^^^^^
 121
 122 Tracker for Video Decode and Presentation API for Unix.
 123
 124 WGL
 125 ^^^
 126
 127 Xorg DDX
 128 ^^^^^^^^
 129
 130 Tracker for Xorg X11 servers. Provides device-dependent
 131 modesetting and acceleration as a DDX driver.
 132
 133 XvMC
 134 ^^^^
 135
 136 Tracker for X-Video Motion Compensation.
 137
 138 Auxiliary
 139 ---------
 140
 141 OS
 142 ^^
 143
 144 The OS module contains the abstractions for basic operating system services:
 145
 146 * memory allocation
 147 * simple message logging
 148 * obtaining run-time configuration option
 149 * threading primitives
 150
 151 This is the bare minimum required to port Gallium to a new platform.
 152
 153 The OS module already provides the implementations of these abstractions for
 154 the most common platforms.  When targeting an embedded platform no
 155 implementation will be provided -- these must be provided separately.
 156
 157 CSO Cache
 158 ^^^^^^^^^
 159
 160 The CSO cache is used to accelerate preparation of state by saving
 161 driver-specific state structures for later use.
 162
 163 .. _draw:
 164
 165 Draw
 166 ^^^^
 167
 168 Draw is a software :term:`TCL` pipeline for hardware that lacks vertex shaders
 169 or other essential parts of pre-rasterization vertex preparation.
 170
 171 Gallivm
 172 ^^^^^^^
 173
 174 Indices
 175 ^^^^^^^
 176
 177 Indices provides tools for translating or generating element indices for
 178 use with element-based rendering.
 179
 180 Pipe Buffer Managers
 181 ^^^^^^^^^^^^^^^^^^^^
 182
 183 Each of these managers provides various services to drivers that are not
 184 fully utilizing a memory manager.
 185
 186 Remote Debugger
 187 ^^^^^^^^^^^^^^^
 188
 189 Runtime Assembly Emission
 190 ^^^^^^^^^^^^^^^^^^^^^^^^^
 191
 192 TGSI
 193 ^^^^
 194
 195 The TGSI auxiliary module provides basic utilities for manipulating TGSI
 196 streams.
 197
 198 Translate
 199 ^^^^^^^^^
 200
 201 Util
 202 ^^^^
 203
