Please note that items in the matrix represent big pieces of functionality, so the matrix is updated rarely. For a better view of daily progress, please see the logs of the source code repositories.
- DONE means that developers think it is fully implemented. It may however contain bugs.
- MOSTLY means that it is mostly implemented and may have known bugs.
- WIP means that someone has started on the initial implementation.
- TODO means that someone needs to write the code. The required knowledge to write the code may or may not be known. Please ask on #nouveau if you want to get your feet wet on this.
- STALLED means that whatever code has been written is accumulating color and texture similar to that 3 week old slice of pizza in your fridge.
- BIOS means "if supported by your BIOS". No software support yet.
- SLOW means that the feature is implemented, but it is slow. Improvements may or may not be planned.
- EXTFW means that the feature is usable, but requires firmware from the binary driver.

1 NV0x family only supports swizzled textures, which we can't use for 2D stuff for various reasons. So no acceleration of XRENDER on those.
2 Note Xv, not XvMC. See the "video decoding accel" line for accelerated decoding.
3 Works, if the VBIOS gives enough memory bandwidth by default. That is, usually yes.
4 nv0x-nv2x (nv17-nv19 excluded) need an external, third-party manufactured TV encoder. Only some Chrontel branded chips are currently supported. For the rest, you cay try nvtv; make sure to set X to the right resolution first.
6 SLI or even multicard setups are very rare among developers. You should start hacking with us, if you have such a setup.
7 It's slow, because proper power management isn't finished yet.
8 nouveau_vieux supports everything that the hardware supports (except nv20 shaders), but there are some parts of OpenGL not directly supported by the hardware (e.g. glClipPlane)
9 The hardware overlay isn't used, which is suboptimal (esp on pre-NV30). Work was done in a pre-KMS driver to support hardware overlays by ArthurHuillet. This support currently exists as KMS planes, but the DDX does not take advantage of them (yet).
Note : Disable Composite on low-end cards for better XVideo performance.
