Testing the amdgpu-powerplay brandh I have several issues.
The first and possibly the cause of others (so for now I won't do separate bugs) is on boot I see -
Can't find requested voltage id in vdd_dep_on_sclk table!
Testing Games/demos all is good and perf is as expected.
Testing UVD however and perf is way worse than before powerplay.
I see in dmesg -
[ 1818.011402] Failed to send Message. [ 1818.011407] Failed to send Previous Message.
After doing this I also may no longer get good perf from gamed/demos.
Trying to force high for the uvd test doesn't help and I notice another issue -
/sys/class/drm/card0/device/power_dpm_force_performance_level
is auto to start with, if I echo high > it works = GPU gets hotter, but I can't change it back. If I echo auto > ... then cat it, it will still say high and GPU remains hot.
Separately when I quit X I may get some new errors in dmesg
