Subject: [PATCH] drm/amdgpu: Direct ret in ras_reset_err_cnt on VF
Date: Thu, 3 Apr 2025 10:40:16 -0400 [thread overview]
Message-ID: <20250403144016.30030-1-yunru.pan@amd.com> (raw)
With adding sriov_vf check, we directly return EOPNOTSUPP in
ras_reset_error_count as we should not do anything on VF to reset RAS error
count.
This also fixes the issue that loading guest driver causes register
violations.
