drm/amdgpu: restrict debugfs register access under SR-IOV

2020-04-13T16:01:04Z

Under bare metal, there is no more else to take care of the GPU register access through MMIO. Under Virtualization, to access GPU register is implemented through KIQ during run-time due to world-switch. Therefore, under SR-IOV user can only access debugfs to r/w GPU registers when meets all three conditions below. - amdgpu_gpu_recovery=0 - TDR happened - in_gpu_reset=0 v2: merge amdgpu_virt_can_access_debugfs() into amdgpu_virt_enable_access_debugfs() v3: drop ret variable in amdgpu_virt_enable_access_debugfs() and directly return result Signed-off-by: Yintian Tao Acked-by: Alex Deucher Signed-off-by: Alex Deucher
