Xming and I will probably do that once we get the git server up.
I have found that on my computer I have maxed out my video performance with Torcs racing sim on the Frosa track. I no longer get better FPS with further improvements. But I get a more responsive game. On tracks with simpler scenery the FPS seems to be still going up.
I attribute these changes to my GPU being maxed out for processing power on the Frosa track but I have more CPU cycles to do the simulation with. On tracks with simpler scenery I'm not saturating the GPU and with the CPU cycles saved I can feed the GPU more data.
I'm currently out of ideas on how to improve the KMS code path much more. I have however improved the non KMS code more and there also should be some slight improvements to r100, 300, and 500 chips do to these changes.
I'll probably have another set of patches by the this weekend.

If you set up a git repo, you may want to poke the Zen Kernel guys, as I guess Zen Kernel users are your target demographic which I assume is users looking for that extra 1% or 2% in performance.

As I understand it xming is working on setting up a public git repo

Is there any sane reason these patches are being distributed as they are instead of as commits in a cloned git repo? github is free, gitorious is free, sourceforge git is free, google code git is free...

Just got the patches, tested and working, although I don't see (subjectively) performance difference.
patch against .33-rc or radeon-testing
Patch against 20100113 (the previous patches from obscene_cnn).

tested your new set of patches, work great. I had previously performance problem with glxgears, but found the problem, it was caused by kwin desktop effect, apparently that ate so much performance compared to compiz.
Now w/o your patches glxgears runs at 2000~2100 fps, with it it runs at 2300~2370. Biggest improvement comes from ut2004, unplayable framerate to somehow more playable, I need to play more maps to judge the difference.
I have produced a bz2 which contains the 3 patchs in one, a bit easier to download and apply (cleanly to 2.6.32-drm-radeon-testing) here. Obscene_CNN, I hope you don't mind.Last edited by xming; 15 January 2010, 07:53 AM.
