Priority: medium Bug ID: 75719 Assignee: dri-devel@lists.freedesktop.org Summary: mplayer -vo gl consume more CPU on r200 Severity: normal Classification: Unclassified OS: Linux (All) Reporter: smoki00790@gmail.com Hardware: x86 (IA32) Status: NEW Version: XOrg CVS Component: DRM/Radeon Product: DRI
OS is current Debian Sid 32bit, card 1002:5960...
So this is on r200 i spotted playing any video file vith gl render (but also many videos in games are also affected), bisecting says it started with this code in ttm:
http://cgit.freedesktop.org/~airlied/linux/commit/?h=drm-next&id=a095c60...
And it performs the same also in 3.14-rc5 kernel :). It consume cca 40% or more CPU power after that commit... that *more* depends on video file and if it is in game or playing video file with mplayer -vo gl.
Mesa version seems doesn't metter i tried 9.2 git, 10.0 git, 10.1 git and current git master.
