drm/amdgpu: Only check for S0ix if AMD_PMC is configured

2021-03-09T10:21:21+00:00

commit 31ada99bdd1b4d6b80462eeb87d383f374409e2a upstream. The S0ix check only makes sense if the AMD PMC driver is present. We need to use the legacy S3 pathes when the PMC driver is not present.

drm/amdgpu: Add check to prevent IH overflow

2021-03-07T11:35:52+00:00

[ Upstream commit e4180c4253f3f2da09047f5139959227f5cf1173 ] Similar to commit ("drm/amdgpu: fix IH overflow on Vega10 v2"). When an ring buffer overflow happens the appropriate bit is set in the WPTR register which is also written back to memory. But clearing the bit in the WPTR doesn't trigger another memory writeback. So what can happen is that we end up processing the buffer overflow over and over again because the bit is never cleared. Resulting in a random system lockup because of an infinite loop in an interrupt handler. Reviewed-by: Christian König Signed-off-by: Defang Bo Signed-off-by: Alex Deucher Signed-off-by: Sasha Levin
