https://bugs.freedesktop.org/show_bug.cgi?id=28411 Summary: Output polling causes latency every 10 seconds Product: DRI Version: DRI CVS Platform: x86-64 (AMD64) OS/Version: Linux (All) Status: NEW Severity: major Priority: medium Component: General AssignedTo: dri-devel@xxxxxxxxxxxxxxxxxxxxx ReportedBy: marius.groeger@xxxxxx The output polling in drm_crtc_helper.c added in this commit: commit eb1f8e4f3be898df808e2dfc131099f5831d491d Author: Dave Airlie <airlied@xxxxxxxxxx> Date: Fri May 7 06:42:51 2010 +0000 causes drm latencies every 10 seconds. I observed them in mythtv. Apparently the dev->mode_config.mutex is held for too long; if I remove the mutex_lock/unlock for testing purposes the latencies are gone. -- Configure bugmail: https://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug. _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/dri-devel
