Subject: [PATCH] drm/amdgpu: move vram recover into sriov full access
[what]
currently driver recover vram after full access, which may hit a corner case that meanwhile another whole gpu reset may be triggered by another VF, which will cause vram recover fail then fail the whole device reset.
[how]
move the recover vram into full access. So another bad VF will not disturb the recover sequence for this vf.
