I didn't look much at perf output lately, will have to try and see if this is still an issue with latest mesa, and report back. -- Configure bugmail: https://bugzilla.kernel.org/userprefs.cgi?tab=email --- You are receiving this mail because: --- You are watching the assignee of the bug.

https://bugzilla.kernel.org/show_bug.cgi?id=33512 --- Comment #2 from Michel D?nzer 2011-08-05 07:25:50 --- My best guess is that it's page flipping related, but it would be good to confirm that, e.g. by somehow triggering a backtrace from atombios_crtc_disable. It might also be interesting to add some debugging output to atombios_crtc_disable to narrow down where it's spending so much time. But if my assumption turns out to be true that it keeps getting called on page flips, we might just need to somehow no-op repeated calls. -- Configure bugmail: https://bugzilla.kernel.org/userprefs.cgi?tab=email --- You are receiving this mail because: --- You are watching the assignee of the bug.
