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 it is thought to be fully implemented. May 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 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.: The current specification for XvMC is considered not worth the amount of work required, as the XvMC interface is too limited to be useful with current video formats. Some work is happening on implementing video acceleration within Gallium3D.
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.
5 - Multicard support requires ability to cold-boot the secondary card(s), ie. initialise them without help from their Video BIOS (since it isn't run on startup). This means that you need all your secondary cards to support multicard, but you can use anything as your primary card. Primary in this context means the card that was set up as primary display by your machine's BIOS, secondary means any card that is not the primary card. Also, atm there's a bug that makes running a GPU-intensive application (mostly 3d, but some 2d also do the trick) on one GPU temporarily freeze the others...
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.
Note : there is no NV03 (riva 128 family) support, neither in progress, nor planned. NV03 differs too much from the other chips to be added to a unified driver. A separate driver for NV01/NV03 would probably be the way to go.
Note2 : disable Composite on low-end cards for better XVideo performance.
