Subject: [PATCH 0262/1110] drm/amdgpu: always repost cards that support SR-IOV
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Generally a good idea between VM sessions. We need a way to
detect VM pass-through in general and always run asic_init in
that case.
