Are these in a branch somewhere? If not I'll try apply the mbox from patchwork.freedesktop.org

This patch set cleans up and attempts to make runtime pm more
reliable in radeon and amdgpu on PX systems. If you have a PX
system that requires setting the runpm=0 module parameter for
stability, please try this patch set.
The main fix is that a minimum of 200ms of delay is required between
a dGPU power down and a power up.
This patch also properly handles the detection of the ATPX dGPU
power control method properly and handles dGPU power control for
platforms that do not support the ATPX dGPU power control method.
