Subject: [PATCH 1/4] drm/amdgpu: Add Runtime Bad Page message definitions for
VFs
Currently VFs rely on poison consumption interrupt from HW to kick off the bad
page retirement process. Part of this process includes a VF reset.
This patch adds the following:
1) Host Bad Pages notification message.
2) Guest request bad pages message.
When combined, VFs are able to reserve the pages early, and potentially avoid
future poison consumption that will disrupt user services from consequent FLR.
