    Yuppy, an awesome news for everyone who needs 32bit mesa:

    Multiarch xserver/mesa is in the process of being uploaded to natty and oneiric, this transition will take some time to work out and it's advised not to use the PPA if you are using proprietary drivers.

    SNA is now enabled for all generations.

    Default Updates

    Mesa
    • my packages now include the glsl-to-tgsi branch. See this Phoronix article for more info
    • mesa 7.11 was branched, the packages still use master branch which will become 7.12/8.0
    • mesa improvements: r600g improvements, WebGL support on Firefox 6

    pls use -O2 if you build intel graphics driver. it gives 20%performance boost in eg lightsmark 2008. radeon does not benefit much from that optimisations, but intel igps run some opengl parts on software. even sandybridge i guess. so pls use the standard mesa compiler options for building

    Someone even uses -O3 with intel.

    Interesting. Since 7.12~git1107040958.39fecd I reverted to -O2. Let me know if it improves performance, or if there are other things slowing it (e.g. --enable-debug flag or glsl-to-tgsi branch).

    You might want to add -fno-builtin-memcmp. Supposedly a big boost, but in my tests I saw no measurable difference. Could be more useful in an app swapping shaders more often.

    I read the thread on mesa-dev about it (summary here), but I think it's better to wait a bit for an upstream solution rather than workaround it in my packages. I may add it in the following days if upstream doesn't address it.

    its abit better. now got 35 instead of 30 fps. self compiled gives 36 fps. so it seems ok. but there is a generel regression. was 40 fps before. but could be my fault. thx for switching to -O2

    Nice job on the drivers. Xorg-edgers is being retarded as of late, so been using this for a while now.
