26 To support migration of multiple devices that might do P2P transactions between
27 themselves, VFIO migration uAPI defines an intermediate P2P quiescent state.
28 While in the P2P quiescent state, P2P DMA transactions cannot be initiated by
30 outstanding P2P transactions are guaranteed to have been completed by the time
33 All the devices that support P2P migration are first transitioned to the P2P
35 safe P2P-wise, since starting and stopping the devices is not done atomically
39 support P2P migration. Single VFIO device migration is allowed regardless of
40 P2P migration support.

149 support it is similar, except that the relevant states for precopy and P2P are
