Current Status of Gallium3D Pipes and State Trackers

This table lists the current combinations of state trackers and pipe drivers.

Explanation:

  • d3d1x: Direct 3D 10/11
  • g3dvl: Generic GPU-Accelerated Video Decoding
  • vega: OpenVG - The Standard for Vector Graphics Acceleration
  • egl: Windowing system trackers similar to dri of EGL standard.
  • wgl: Windowing system trackers similar to dri for MS Windows.

Unlisted drivers:

  • identity: This is a skeleton driver, used for passthrough and wrapping of pipes.
  • nouveau: This is not actually a driver, but a set of routines common to all nv pipes.
  • trace: This is a passthrough driver that traces Gallium library calls.

State tracker conformance tests:

  • mesa: tri, gears, piglit. tri and gears must render correctly and not crash; piglit must pass.
  • vega: None.
  • exa: rendercheck. This should be a goal for improving exa, drivers bound to exa, and rendercheck.
  • g3dvl: None.
  • dri: glxinfo. Must say that direct rendering is enabled.
  • xorg: Xorg. X server must come up. Input drivers do not matter.
  • egl: eglinfo, eglscreen, egltri. egltri must render correctly.
  • wgl: None.

What do these mean?

  • "DONE" means that it is implemented and passes the state-tracker-specific conformance test.
  • "MOSTLY" means that it is implemented but does not pass the conformance test.
  • "WIP" means that the implementation is being worked on, but should not be considered ready for general testing.
  • "SLOW" means that the feature is DONE, but not performant due to known deficiencies in the code.
  • "TODO" means that the implementation is incomplete and nobody is working on it.
  • "UNKNOWN" means that the current status of this item isn't known.

If you're the maintainer of any of this code, please update these when you can, especially UNKNOWN slots.
