Does current Git master work better? At least some of the Gallium code was not detecting the endianness of this architecture correctly. Created attachment 50365 [details]

Hi Michel, Sorry for the very late reply! But it was worth waiting for it: I just finished recompiling current Git master (Mesa 7.12-devel (git-ccecc08)). As you can see in the attached screenshot, glxgears now renders correctly :-) I don't know though if 3D hardware acceleration is fully working: I get no particular warning/error in dmesg or Xorg.0.log, but glxgears FPS seem very low to me (~85 FPS).

As the glxgears output explains, it synchronizes to the refresh rate by default, so that may be okay. Check the glxinfo output, and maybe try vblank_mode=0 glxgears to disable synchronization.

I also gave ioQuake3-based Debian "Wheezy" Testing quake3 a try. Ran flawlessly. |
