Thanks you for testing! After some additional testing I've noticed I hit similar issue. My GPU just keeps running on current engine clock without reclocking. That's because I don't get VBLANK IRQ for some reason. [glxgears start] [ 80.783033] [drm] pm.planned_action = RADEON_PM_ACTION_UPCLOCK [ 81.083015] [drm] pm.vblank_callback = true [ 81.096860] [drm] radeon_pm_reclock_work_handler [ 81.096863] [drm] pm.vblank_callback = false [ 81.096867] [drm] radeon_atom_set_engine_clock 680000 KHz [ 81.103097] [drm] pm.planned_action = RADEON_PM_ACTION_NONE [glxgears stop] [ 85.585011] [drm] pm.planned_action = RADEON_PM_ACTION_DOWNCLOCK [ 85.685032] [drm] pm.planned_action = RADEON_PM_ACTION_NONE [ 87.686051] [drm] pm.planned_action = RADEON_PM_ACTION_DOWNCLOCK [ 87.986088] [drm] pm.vblank_callback = true [glxgears start] [ 209.707912] [drm] radeon_pm_reclock_work_handler I've started glxgears and this did upclock my engine. That was fine. When I stopper my PM noticed GPU is not loaded and decided to downclock it. It has set "pm.vblank_callback = true" but for some reason IRQ didn't happen (and so it didn't call reclocking function). Finally when I decided to start glxgears again VBLANK has came but it was way too late of course :| Could someone explain that IRQs issue, please? -- Rafał ------------------------------------------------------------------------------ This SF.Net email is sponsored by the Verizon Developer Community Take advantage of Verizon's best-in-class app development support A streamlined, 14 day to market process makes app distribution fast and easy Join now and get one step closer to millions of Verizon customers http://p.sf.net/sfu/verizon-dev2dev -- _______________________________________________ Dri-devel mailing list Dri-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/dri-devel
