2022-01-14drm/amd/pm: do not expose implementation details to other blocks out of powerEvan Quan
Those implementation details(whether swsmu supported, some ppt_funcs supported, accessing internal statistics ...)should be kept internally. It's not a good practice and even error prone to expose implementation details.

2021-04-09drm/amdgpu: split umc callbacks to ras and non-ras onesHawking Zhang

2020-04-13drm/amdgpu: refine ras related message printGuchun Chen
Prefix ras related kernel message logging with PCI device info by replacing DRM_INFO/WARN/ERROR with dev_info/warn/err. This can clearly tell user about GPU device information where ras is. And add some other ras message printing to make it more clear and friendly as well.

2020-04-13drm/amdgpu: add uncorrectable error count print in UMC ecc irq cbGuchun Chen
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.
