drm/amdgpu: introduce vram lost for reset (v2)

2019-08-29T20:52:32Z

for SOC15/vega10 the BACO reset & mode1 would introduce vram lost in high end address range, current kmd's vram lost checking cannot catch it since it only check very ahead visible frame buffer v2: cover NV as well Signed-off-by: Monk Liu Reviewed-by: Alex Deucher Signed-off-by: Alex Deucher

drm/amdgpu: simplify and cleanup setting the dma mask

2019-08-15T15:51:01Z

Use dma_set_mask_and_coherent to set both masks in one go, and remove the no longer required fallback, as the kernel now always accepts larger than required DMA masks. Fail the driver probe if we can't set the DMA mask, as that means the system can only support a larger mask. Reviewed-by: Christian König Signed-off-by: Christoph Hellwig Signed-off-by: Alex Deucher

drm/amdgpu: put the SMC into the proper state on reset/unload

2019-07-31T04:24:44Z

When doing a GPU reset or unloading the driver, we need to put the SMU into the apprpriate state for the re-init after the reset or unload to reliably work. I don't think this is necessary for BACO because the SMU actually controls the BACO state to it needs to be active. For suspend (S3), the asic is put into D3 so the SMU would be powered down so I don't think we need to put the SMU into any special state. Reviewed-by: Evan Quan Signed-off-by: Alex Deucher

drm/amdgpu: add an asic callback to determine the reset method

2019-07-31T04:23:44Z

Sometimes the driver may have to behave differently depending on the method we are using to reset the GPU. Reviewed-by: Evan Quan Signed-off-by: Alex Deucher
