H A Dvfio.rst70 * A ``switchover_start`` function that in the multifd mode starts a thread that
71 reassembles the multifd received data and loads it in-order into the device.
72 In the non-multifd mode this function is a NOP.
75 in the non-multifd mode.
76 In the multifd mode it just emits either a dummy EOS marker.
80 vendor driver indicates that no data remains. In the multifd mode it
83 * A ``save_complete_precopy_thread`` function that in the multifd mode
84 provides thread handler performing multifd device state transfer.
