[PATCH] drm/amdgpu: report bad status in GPU recovery

[Zhang, Hawking]

[AMD Official Use Only - AMD Internal Distribution Only]

Right, it's functional. My concern is whether the kernel message in amdgpu_ras_eeprom_check_err_threshold will be printed twice. This is the end of gpu recovery (i.e., report gpu reset failed or gpu reset succeed). Check_err_threshold was already done before reaching here.

Regards,
Hawking

I think the if condition in amdgpu_ras_eeprom_check_err_threshold is good enough, no need to update it with is_rma.
