https://bugs.freedesktop.org/show_bug.cgi?id=49603 --- Comment #5 from Simon Farnsworth <simon.farnsworth@xxxxxxxxxxxx> 2012-05-09 02:30:15 PDT --- Created attachment 61271 --> https://bugs.freedesktop.org/attachment.cgi?id=61271 A program to stop the CPU entering low power states Trying a different route. Can you compile the attached program with "gcc -o stopsleep stopsleep.c" and leave it running while playing a video? It tells the kernel to avoid using deep sleep states when idling. If it helps, we have a clue. If it doesn't, and video decode doesn't saturate all your CPU cores, can you try running "while true ; do true ; done" in a background shell and see if that helps? The goal of both of these is to see if the problem is that we're now letting the CPU idle more than we used to, and finding that the resulting power save modes hurt. -- 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
