[AMD Official Use Only - Internal Distribution Only]
Hello Guchun,
Besides this, could you please also make a patch to replace DRM_INFO with dev_info in amdgpu_ras_check_supported. Basically, we'd prefer to have device bdf as the prefix in RAS related wording in kernel message, instead of DRM pre-fix.
Please also have a review again on the other RAS wording in case there is still use DRM_INFO for the print out message. We shall let user know exactly gpu device for any RAS error information.
Regards,
Hawking

Subject: [PATCH] drm/amdgpu: add uncorrectable error count print in UMC ecc irq cb
Uncorrectable error count printing is missed when issuing UMC UE injection. When going to the error count log function in GPU recover work thread, there is no chance to get correct error count value by last error injection and print, because the error status register is automatically cleared after reading in UMC ecc irq callback. So add such message printing in UMC ecc irq cb to be consistent with other RAS error interrupt cases.
