[PATCH V2 06/11] drm/amdgpu: Modify mmhub block to fit for the unified ras block data and ops

yipechai YiPeng.Chai at amd.com
Wed Dec 1 10:52:45 UTC 2021


1.Modify mmhub block to fit for the unified ras block data and ops.
2.Implement .ras_block_match function pointer for mmhub block to identify itself.
3.Change amdgpu_mmhub_ras_funcs to amdgpu_mmhub_ras, and the corresponding variable name remove _funcs suffix.
4.Remove the const flag of mmhub ras variable so that mmhub ras block can be able to be insertted into amdgpu device ras block link list.
5.Invoke amdgpu_ras_register_ras_block function to register mmhub ras block into amdgpu device ras block link list. 5.Remove the redundant code about mmhub in amdgpu_ras.c after using the unified ras block.
6.Remove the redundant code about mmhub in amdgpu_ras.c after using the unified ras block.
