drm/amdgpu: fix a GPU hang issue when remove device

2021-01-06T21:17:27Z

When GFXOFF is enabled and GPU is idle, driver will fail to access some registers. Therefore change to disable power gating before all access registers with MMIO. Dmesg log is as following: amdgpu 0000:03:00.0: amdgpu: amdgpu: finishing device. amdgpu: cp queue pipe 4 queue 0 preemption failed amdgpu 0000:03:00.0: amdgpu: failed to write reg 2890 wait reg 28a2 amdgpu 0000:03:00.0: amdgpu: failed to write reg 1a6f4 wait reg 1a706 amdgpu 0000:03:00.0: amdgpu: failed to write reg 2890 wait reg 28a2 amdgpu 0000:03:00.0: amdgpu: failed to write reg 1a6f4 wait reg 1a706 Signed-off-by: Dennis Li Reviewed-by: Hawking Zhang Signed-off-by: Alex Deucher

drm/amdgpu: add judgement for suspend/resume sequence

2020-12-15T16:32:46Z

S0ix only makes sense on APUs since they are part of the platform, so only when the ASIC is APU should set amdgpu_acpi_is_s0ix_supported flag to deal with the related situation. Signed-off-by: Likun Gao Reviewed-by: Alex Deucher Signed-off-by: Alex Deucher

drm/amdgpu: update amdgpu device suspend/resume sequence for s0i3 support

2020-11-13T22:29:45Z

- Need skip the RLC/CP/GFX disable for let GFXOFF enter during suspend period. - For s0i3 suspend only need suspend DCE and each IP interrupt. - Before VBIOS POSTed check and atom HW INT need set the GPU power status change to D0 in the resume period, otherwise the HW will be mess up and see the SDMA hang. - Need handle the GPU reset path during amdgpu device suspend.
