    I think the last two major issues for getting on par with r6xx/r7xx are fixing mipmaps and stencil buffers.
    Speaking of stencil buffers, are there any news on this bug:

    https://bugs.freedesktop.org/show_bug.cgi?id=28363

    Other than that, Doom3 works perfectly on r600c. It's surprisingly effective even without dynamic shadows, but you do need them for the full experience, though.

    • Just tried out the most recent code, and I'm running into a little corruption, most reproducably in the KDE game KNetwalk when you rotate a tile.

      • difficult to say what you're running into without a screenshot.

        The kernel-patch from this bug solves some corruption issues. It hasn't been merges as of .36-rc4, so you'll need to apply it manually.

        • Ah, Christian (and Alex!), you're a lifesaver. The corruption was annoying in itself, but what I've not seen mentioned is that when corruption was occurring, crashes were proportionately more likely - usually bringing down X for me. Now, both corruption and crashes seem to be gone!

          Excellent stuff, thanks a lot.

          • So is the classic driver looking to be merged into mainline Mesa before the 7.9 window closes?

            Comment


            • As far as I know the merge window is already closed and the 5xxx driver is already merged.

              • Huh. Any idea how long ago that was? I CBFed figuring out of to build my own drivers so I've been taking advantage of the xorg-edgers repo, under the assumption that their Mesa 7.9-devel packages are up-to-date. I figured the new code hadn't been merged, since I'm still stuck with software rendering (and that insufferable aubergine stripe down the left side of my screen, that's been there since the initial modesetting support).

                • AFAIK it went straight into master the day the code was liberated by AMD. But you'll need a ddx from evergreen branch to allow for both 2D and 3D acceleration. And if you don't want any lockups and corruption you'll also need the just released kernel 2.6.36-rc5 at minimum.

                  • Ahh, sod that, then. Thanks for clearing that up.

                    • Great, I see the broken mipmap thing is now fixed.

                      • indeed, mipmaps work. Nice!

                        • Is evergreen support in xorg-edgers repository?

                          wanna try it. and I will grab latest 2.6.36.

                          • I haven't seen a repo for the evergreen-accel branch of xf86-video-ati (which you need for Evergreen accel right now). Once the evergreen-accel branch gets merged into xf86-video-ati master you should be OK.

                              I hope it gets merged soon. FGLRX doesnt work on my system period.. xf86-video-ati is my only hope..

                              • You can download and build the source yourself - it's not that hard.

                                Anyways, I think the merge should happen soon. It was waiting on a couple of things (a -ati release and some evergreen fixes) but I believe the last of those pre-requisites happened yesterday afternoon.
