Card is an AGP RV670. libdrm,mesa,ddx and xorg are current gits.
After the recent batch of commits to drm-radeon-testing I have a perf
problem.
It doesn't show immediately, but after running a timedemo on nexuiz
followed by openarena, further timedemos on either will have very poor
performance - 4 fps and gears may be as low as 100fps.
Nothing in dmesg during bisect (though I saw a few errors when on head -
I think they are a separate issue) and free looks OK.
Once this has happened 2D performance is also reduced a bit - menues on
seamonkey slower than before and when displaying a page with a second
counter, sometimes all rendering will glitch briefly every second - can
be seen just with key repeat in an xterm.
Git bisect came up with -
db78e27de7e29a6db6be7caf607cf803d84094aa is first bad commit
commit db78e27de7e29a6db6be7caf607cf803d84094aa
