[Regression][Bisected] Forcing a specific mclk pstate on Navi10 causes system hang
The changes for Navi 14 in this commit cause my system running a Radeon rx 5700XT to hang when I attempt to force my GPU into the maximum mclk pstate via the following commands with amdgpu.ppfeaturemask=0xffffffff
set
echo "manual" > /sys/class/drm/card0/device/power_dpm_force_performance_level
echo "3" > /sys/class/drm/card0/device/pp_dpm_mclk
This does not occur prior to this commit, and locking the GPU to the highest pstate works as expected.
