FWIW the nouveau thing would probably not involve a lot of reuse... the instructions are fairly different, and a lot of the nouveau project would have to be actually figuring out what _is_ a better schedule rather than just implementing one.

Another project that I think I mentioned on IRC is to go through the ES extension list and add in all the "easy" ones (i.e. ones that are already all or mostly implemented by desktop features), of which there are a _ton_ (probably like 20). I'm just talking about the OES/EXT/KHR ones, not the vendor ones. The majority would be modifying the various paths to allow the logic to be executed in ES contexts and to modify/add piglit tests verifying that the functionality can be used in ES. Here are a bunch of differences between what the nvidia blob exposes and mesa for the same hw: http://people.freedesktop.org/~imirkin/glxinfo/glxinfo.html#p=es&b=version&g=NVIDIA%20GF1xx%20%28GeForce%20400%2C%20500%29&diff Admittedly some of those are ES3.1-only, but far from all. -ilia _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/mesa-dev
