Below errors are reported with S0i3 on Yellow carp where under stress testing with 5.14.0 through 5.14.8.
[drm:amdgpu_device_ip_resume_phase2 [amdgpu]] *ERROR* resume of IP block <sdma_v5_2> failed -110
amdgpu 0000:04:00.0: amdgpu: amdgpu_device_ip_resume failed (-110).
PM: dpm_run_callback(): pci_pm_resume+0x0/0x90 returns -110
amdgpu 0000:04:00.0: PM: failed to resume async: error -110
The patch fixes this by forcing exit gfxoff for sdma resume.
The patch is in 5.15-rc4 (https://github.com/torvalds/linux/commit/26db706a6d77b9e184feb11725e97e53b7a89519)
This is requested by AMD.
[Where problems could occur]
Low risk. This only affects AMD platforms with s0ix supports. The changes repeat what is (should be) done in firmware.
