AMDGPU Power management failure on 290X

Submitted by John-Michael Mulesa

Assigned to Default DRI bug account

Link to original bug (#96885)

Description

Created attachment 124990
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.

Patch 124990, "full dmesg output":
dmesg.log
