Summary: r600 kms, massave slowdown with latest drm-radeon-testing Product: DRI Version: XOrg CVS Platform: x86-64 (AMD64) OS/Version: Linux (All) Status: NEW Severity: normal Priority: medium Component: DRM/Radeon AssignedTo: dri-devel@lists.freedesktop.org ReportedBy: chainsawbike@gmail.com
ive bisected to this commit: http://git.kernel.org/?p=linux/kernel/git/airlied/drm-2.6.git;a=commitdiff;h...
odd thing i noted: if i run compiz with vblank_mode=0 and run glxgears it reports a frame-rate of about 1500 fps ( being the same as i get when running the previous revision kernel) but its still looks as slow as molasses if i unset vblank_mode then run it it reports about 5 fps but looks the same as before
