   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 Cell
  11 ^^^^
  12
  13 Simple driver for the IBM Cell architecture. Runs faster than :ref:`softpipe`
  14 on Cell-based machines.
  15
  16 Failover
  17 ^^^^^^^^
  18
  19 Broken and deprecated.
  20
  21 Intel i915
  22 ^^^^^^^^^^
  23
  24 Driver for Intel i915 and i945 chipsets.
  25
  26 Intel i965
  27 ^^^^^^^^^^
  28
  29 Highly experimental driver for Intel i965 chipsets.
  30
  31 Identity
  32 ^^^^^^^^
  33
  34 Wrapper driver. The identity driver is a simple skeleton that passes through
  35 all of its :ref:`Context` and :ref:`Screen` methods to an underlying Context
  36 and Screen, and as such, it is an excellent starting point for new drivers.
  37
  38 LLVM Softpipe
  39 ^^^^^^^^^^^^^
  40
  41 A version of :ref:`softpipe` that uses the Low-Level Virtual Machine to
  42 dynamically generate optimized rasterizing pipelines.
  43
  44 nVidia nvfx
  45 ^^^^^^^^^^^
  46
  47 Driver for the nVidia nv30 and nv40 families of GPUs.
  48
  49 nVidia nv50
  50 ^^^^^^^^^^^
  51
  52 Driver for the nVidia nv50 family of GPUs.
  53
  54 VMware SVGA
  55 ^^^^^^^^^^^
  56
  57 Driver for VMware virtualized guest operating system graphics processing.
  58
  59 ATI r300
  60 ^^^^^^^^
  61
  62 Driver for the ATI/AMD r300, r400, and r500 families of GPUs.
  63
  64 .. _softpipe:
  65
  66 Softpipe
  67 ^^^^^^^^
  68
  69 Reference software rasterizer. Slow but accurate.
  70
  71 Trace
  72 ^^^^^
  73
  74 Wrapper driver. Trace dumps an XML record of the calls made to the
  75 :ref:`Context` and :ref:`Screen` objects that it wraps.
  76
  77 Rbug
  78 ^^^^
  79
  80 Wrapper driver. :ref:`rbug` driver used with stand alone rbug-gui.
  81
  82 State Trackers
  83 --------------
  84
  85 .. _dri:
  86
  87 Direct Rendering Infrastructure
  88 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  89
  90 Tracker that implements the client-side DRI protocol, for providing direct
  91 acceleration services to X11 servers with the DRI extension. Supports DRI1
  92 and DRI2. Only GL is supported.
  93
  94 .. _egl:
  95
  96 EGL
  97 ^^^
  98
  99 Tracker for the Khronos EGL standard, used to set up GL and GLES contexts
 100 without extra knowledge of the underlying windowing system.
 101
 102 GLX
 103 ^^^
 104
 105 MesaGL
 106 ^^^^^^
 107
 108 Tracker implementing a GL state machine. Not usable as a standalone tracker;
 109 Mesa should be built with another state tracker, such as :ref:`DRI` or
 110 :ref:`EGL`.
 111
 112 Python
 113 ^^^^^^
 114
 115 OpenVG
 116 ^^^^^^
 117
 118 WGL
 119 ^^^
 120
 121 Xorg/XFree86 DDX
 122 ^^^^^^^^^^^^^^^^
 123
 124 Tracker for XFree86 and Xorg X11 servers. Provides device-dependent
 125 modesetting and acceleration as a DDX driver.
 126
 127 Auxiliary
 128 ---------
 129
 130 OS
 131 ^^
 132
 133 The OS module contains the abstractions for basic operating system services:
 134
 135 * memory allocation
 136 * simple message logging
 137 * obtaining run-time configuration option
 138 * threading primitives
 139
 140 This is the bare minimum required to port Gallium to a new platform.
 141
 142 The OS module already provides the implementations of these abstractions for
 143 the most common platforms.  When targeting an embedded platform no
 144 implementation will be provided -- these must be provided separately.
 145
 146 CSO Cache
 147 ^^^^^^^^^
 148
 149 The CSO cache is used to accelerate preparation of state by saving
 150 driver-specific state structures for later use.
 151
 152 .. _draw:
 153
 154 Draw
 155 ^^^^
 156
 157 Draw is a software :term:`TCL` pipeline for hardware that lacks vertex shaders
 158 or other essential parts of pre-rasterization vertex preparation.
 159
 160 Gallivm
 161 ^^^^^^^
 162
 163 Indices
 164 ^^^^^^^
 165
 166 Indices provides tools for translating or generating element indices for
 167 use with element-based rendering.
 168
 169 Pipe Buffer Managers
 170 ^^^^^^^^^^^^^^^^^^^^
 171
 172 Each of these managers provides various services to drivers that are not
 173 fully utilizing a memory manager.
 174
 175 Remote Debugger
 176 ^^^^^^^^^^^^^^^
 177
 178 Runtime Assembly Emission
 179 ^^^^^^^^^^^^^^^^^^^^^^^^^
 180
 181 TGSI
 182 ^^^^
 183
 184 The TGSI auxiliary module provides basic utilities for manipulating TGSI
 185 streams.
 186
 187 Translate
 188 ^^^^^^^^^
 189
 190 Util
 191 ^^^^
 192
