Hi,
Some OEM platforms containing AMD APU + AMD dGPU contain ACPI _PR3 objects that are mistakenly activating the wrong power management features.
This is fixed in mainline by the following commits that backport cleanly to 5.17.y:
commit 901e2be20dc5 ("drm/amdgpu: move PX checking into amdgpu_device_ip_early_init")
commit 85ac2021fe3ac ("drm/amdgpu: only check for _PR3 on dGPUs")
Can you please bring these to 5.17.y? They *do not* backport cleanly to earlier stable trees, and a separate backport will be submitted for those.
Thanks,
