[July 14 status update : glxgears buffer aging problem found & fixed, texture code pushed but not sure of status. Buffer swap (back to front copy) being done on CPU rather than GPU so glxgears gives ~15fps rather than ~1500. Most testing is being done on rv730/770; there were a few color problems on 6xx and RS780 last time I looked, probably still there for now. See Alex's blog entry for more details - www.botchco.com/agd5f/]

The 6xx/7xx 3D driver is starting to do useful things again after moving over to the radeon-rewrite mesa code base. As of last night, it seems to be behaving properly on 14 of the 63 tests in progs/redbook, drawing incorrectly on 24, and either not drawing or crashing on the remaining 25. Cooper found that the following tests rendered correctly : 

hello, plane, torus, list, aargb, smooth, tess, varray, tesswind, model, anti, bezcurve, picksquare, and cube.

The driver currently segfaults after running ~10 frames of glxgears - Richard is looking into that. Alex is hooking up the texture code to the new bufmgr code, and Cooper is going through the redbook tests and picking off problems as he finds them. Development and testing are primarily being done on discrete graphics cards; not sure of the current status on 760/780/790 IGP parts.

The r6xx-rewrite branch was synced up with mesa master recently, so merging it into master should be fairly straightforward. A bigger question is how and when we decide that the API to the drm is not likely to require further changes, ie when it makes sense to ask to merge the new drm ioctl support into the main kernel tree. The changes are relatively small and the chance of breaking any *other* support is extremely low, so maybe there's a chance of making 2.6.31 but we haven't had that discussion yet AFAIK.

If you want to try the latest code (with the caveat that it is *not* ready for general use), you want the r6xx-rewrite of mesa/mesa, and the r6xx-r7xx-3d branch of ~agd5f/drm. The drm code works with 2.6.28 and earlier, but has problems with 2.6.29 and higher.
