RE: [PATCH V2 11/11] drm/amdgpu: Move error inject function from amdgpu_ras.c to each block

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

 



[AMD Official Use Only]

The error injection has no difference among RAS blocks except GFX and XGMI.
I agree to move the xgmi error injection to amdgpu_xgmi.c, but I don't think it's necessary to implement specific error injection functions for all other RAS blocks.

Regards,
Tao
