I get the same error messages (write error: Invalid argument) when echoing the values into power_dpm_force_performance_level. During idle (XFCE with or without composite), it remains on power level 2: # cat /sys/kernel/debug/dri/0/radeon_pm_info uvd vclk: 0 dclk: 0 power level 2 sclk: 87500 mclk: 120000 vddc: 1200 vddci: 1100 (Temperature is around 48C) When playing a video, the states change (card gets cooler): # cat /sys/kernel/debug/dri/64/radeon_pm_info uvd vclk: 50000 dclk: 40000 power level 1 sclk: 40000 mclk: 90000 vddc: 950 vddci: 1100 # cat /sys/kernel/debug/dri/64/radeon_pm_info uvd vclk: 50000 dclk: 40000 power level 2 sclk: 40000 mclk: 90000 vddc: 950 vddci: 1100 # cat /sys/kernel/debug/dri/64/radeon_pm_info uvd vclk: 50000 dclk: 40000 power level 0 sclk: 40000 mclk: 90000 vddc: 950 vddci: 1100 (Temperature is around 44C) The Windows driver brings the temperature down to 37C in idle. -- You are receiving this mail because: You are watching the assignee of the bug. _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/dri-devel
