[AMD Official Use Only] +static void umc_query_error_status_helper(struct amdgpu_device *adev, + uint64_t mc_umc_status, uint32_t umc_reg_offset) Might be better keep umc_v6_7 naming style. Call it umc_v6_7_query_mca_status. Apart from that, the patch is Reviewed-by: Hawking Zhang <Hawking.Zhang@xxxxxxx> Regards, Hawking -----Original Message----- From: Stanley.Yang <Stanley.Yang@xxxxxxx> Sent: Friday, April 8, 2022 16:10 To: amd-gfx@xxxxxxxxxxxxxxxxxxxxx; Zhang, Hawking <Hawking.Zhang@xxxxxxx>; Zhou1, Tao <Tao.Zhou1@xxxxxxx>; Li, Candice <Candice.Li@xxxxxxx> Cc: Yang, Stanley <Stanley.Yang@xxxxxxx> Subject: [PATCH Review 1/1] drm/amdgpu: add umc query error status function In order to debug ras error, driver will print IPID/SYND/MISC0 register value if detect correctable or uncorrectable error. Provide umc_query_error_status_helper function to reduce code redundancy.
