drm/amdgpu: Move umc ras block init to gmc ras sw_init2023-03-13T21:27:48ZHawking Zhang2023-03-11T09:36:11Zurn:sha1:a6dcf9a7ccfed57abd44c24cc505b559281d44b9
Initialize umc ras block only when umc ip block
supports ras. Driver queries ras capabilities after
early_init, ras block init needs to be moved to
sw_init.

Don't need to query error count and error address on harvest umc nodes.
v2: Fix code bug, use active_mask instead of harvsest_config
and remove unnecessary argument in LOOP macro.
v3: Leave adev->gmc.num_umc unchanged.

drm/amdgpu: move convert_error_address out of umc_ras2022-10-17T21:41:21ZHawking Zhang2022-10-14T07:17:43Zurn:sha1:6c0ca748205dc815505c6de79ecf565953390b66
RAS error address translation algorithm is common
across dGPU and A + A platform as along as the SOC
integrates the same generation of UMC IP.
UMC RAS is managed by x86 MCA on A + A platform,
umc_ras in GPU driver is not initialized at all on
A + A platform. In such case, any umc_ras callback
implemented for dGPU config shouldn't be invoked
from A + A specific callback.
The change moves convert_error_address out of dGPU
umc_ras structure and makes it share between A + A
and dGPU config.
