That patch will break any attempt to sync swaps to vblank. The right fix is more like "only enable the vblank interrupt when a buffer swap request comes in that wants it". I think this should be in rawhide and working already... can you re-test it please? OK, installed xorg-x11-drv-ati-6.6.193-2.fc8 from the development repo, but when X is running the ATI Radeon card still generates 60+ wakeups a second. I will attach the xorg.conf and Xorg.log as well if that helps. Created attachment 180081 [details]

you need a new kernel I just realised as well, this stuff is only gone upstream for 2.6.23, radeon drm 1.27 isn't new enough to support this.. OK, I upgraded to kernel-2.6.23-0.74.rc2.git1.fc8 and now the system generates about 45 wakeups/second sitting at the GDM login screen instead of well over 100. Looks a lot better! Wakeups-from-idle per second : 46.0 Top causes for wakeups: 41.4% ( 18.3) at-spi-registry : schedule_timeout (process_timeout) 30.1% ( 13.3) Xorg : do_setitimer (it_real_fn) 6.0% ( 2.7) <kernel core> : clocksource_register (clocksource_watchdog) 3.0% ( 1.3) ip : tg3_open (tg3_timer) 3.0% ( 1.3) ntpd : schedule_timeout (process_timeout) 3.0% ( 1.3) <kernel core> : queue_delayed_work_on (delayed_work_timer_fn) The next one on the list is known bug #227476. |
