[PATCH V3 09/12] drm/amdgpu: Modify sdma block to fit for the unified ras block data and ops

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



1.Modify sdma block to fit for the unified ras block data and ops.
2.Change amdgpu_sdma_ras_funcs to amdgpu_sdma_ras, and the corresponding variable name remove _funcs suffix.
3.Remove the const flag of sdma ras variable so that sdma ras block can be able to be inserted into amdgpu device ras block link list.
4.Invoke amdgpu_ras_register_ras_block function to register sdma ras block into amdgpu device ras block link list.
5.Remove the redundant code about sdma in amdgpu_ras.c after using the unified ras block.
6.Fill unified ras block .name .block .ras_late_init and .ras_fini for all of sdma versions. If .ras_late_init and .ras_fini had been defined by the selected sdma version, the defined functions will take effect; if not defined, default fill them with amdgpu_sdma_ras_late_init and amdgpu_sdma_ras_fini.
