Bug ID: 97403
Summary: AMDGPU/Iceland DPM not properly working on 4.9-wip
Product: DRI
Version: unspecified
Hardware: x86-64 (AMD64)
OS: Linux (All)
Status: NEW
Severity: normal
Priority: medium
Component: DRM/AMDgpu
Assignee: dri-devel at lists.freedesktop.org
Reporter: krejzi at email.com
4.9-wip branch should have proper DPM support for Iceland. However, this
doesn't seem to work. I can't manually force "high" performance by issuing:
# echo high > /sys/class/drm/card1/device/power_dpm_force_performance_level
bash: echo: write error: Invalid argument
dmesg has one weird note, and that is:
[ 20.998755] VI should always have 2 performance levels
