H A Dp2pdma.rst9 called Peer-to-Peer (or P2P). However, there are a number of issues that
10 make P2P transactions tricky to do in a perfectly safe way.
17 only supports doing P2P when the endpoints involved are all behind the
24 memory that is used for P2P transactions needs to be backed by struct
33 In a given P2P implementation there may be three or more different
36 * Provider - A driver which provides or publishes P2P resources like
49 in that it exposes any CMB (Controller Memory Buffer) as a P2P memory
50 resource (provider), it accepts P2P memory pages as buffers in requests
56 to the P2P memory (CMB) and then to the NVMe device (and vice versa).

H A Dvfio.rst26 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.
148 supports both precopy and P2P migration. The flow for devices that don't
149 support it is similar, except that the relevant states for precopy and P2P are
