| 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. |
| |
| Identity |
| ^^^^^^^^ |
| |
| Wrapper driver. The identity driver is a simple skeleton that passes through |
| all of its :ref:`Context` and :ref:`Screen` methods to an underlying Context |
| and Screen, and as such, it is an excellent starting point for new drivers. |
| |
| LLVM Softpipe |
| ^^^^^^^^^^^^^ |
| |
| A version of :ref:`softpipe` that uses the Low-Level Virtual Machine to |
| dynamically generate optimized rasterizing pipelines. |
| |
| nVidia nvfx |
| ^^^^^^^^^^^ |
| |
| Driver for the nVidia nv30 and nv40 families of GPUs. |
| |
| nVidia nv50 |
| ^^^^^^^^^^^ |
| |
| Driver for the nVidia nv50 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. |
| |
| .. _softpipe: |
| |
| Softpipe |
| ^^^^^^^^ |
| |
| Reference software rasterizer. Slow but accurate. |
| |
| 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. |
| |
| .. _galahad: |
| |
| Galahad |
| ^^^^^^^ |
| |
| Wrapper driver. Sanity checker for the internal gallium state. Normally |
| a driver should n't have to sanity check the input it gets from a state |
| tracker. Any wrong state received should be perceived as a state tracker bug. |
| |
| State Trackers |
| -------------- |
| |
| .. _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. |
| |
| .. _egl: |
| |
| EGL |
| ^^^ |
| |
| Tracker for the Khronos EGL standard, used to set up GL and GLES contexts |
| without extra knowledge of the underlying windowing system. |
| |
| 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`. |
| |
| Python |
| ^^^^^^ |
| |
| OpenVG |
| ^^^^^^ |
| |
| WGL |
| ^^^ |
| |
| Xorg/XFree86 DDX |
| ^^^^^^^^^^^^^^^^ |
| |
| Tracker for XFree86 and 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 |
| ^^^^ |
| |
| 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 |
| ^^^^ |
| |
