2024-10-24drm/amdkfd: sever xgmi io link if host driver has disable sharingJonathan Kim
Host drivers can create partial hives per guest by disabling xgmi sharing between certain peers in the main hive. Typically, these partial hives are fully connected per guest session. In the event that the host makes a mistake by adding a non-shared node to a guest session, have the KFD reflect sharing disabled by severing the IO link.
