Created attachment 124990 [details] [review] full dmesg output It appears that DPM support is broken in amdgpu for the XFX 290X. Here is the most interesting line from dmesg: [drm:ci_dpm_sw_init [amdgpu]] *ERROR* Invalid PCC GPIO: 13! When running on the radeon driver, I see a framerate of about 20fps (at 4k) on Unigine Heaven, while with amdgpu it's hovering around 5fps all else being equal. I'm under the impression that amdgpu/radeon performance for Sea Islands cards should be roughly equal. I've attached the whole dmesg log, but I'm happy to provide any additional info to help troubleshoot this issue.
Some additional info after finding bug 87457 and 82201: cat /sys/kernel/debug/dri/64/amdgpu_pm_info uvd disabled vce disabled power level avg sclk: 30000 mclk: 15000 GPU load: 0 % cat /sys/kernel/debug/dri/64/amdgpu_pm_info uvd disabled vce disabled power level avg sclk: 100000 mclk: 15000 GPU load: 100 % Attached xorg and vbios as well.
