Update the list with supported Arcturus chips, but disable for now until final list is confirmed. Ideally we can poll atombios for FRU support, instead of maintaining this list of chips, but this will enable serial number reading for supported ASICs for the time-being. Signed-off-by:

Uncorrectable error count printing is missed when issuing UMC UE injection. When going to the error count log function in GPU recover work thread, there is no chance to get correct error count value by last error injection and print, because the error status register is automatically cleared after reading in UMC ecc irq callback. So add such message printing in UMC ecc irq cb to be consistent with other RAS error interrupt cases. Signed-off-by:

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:
