This function currently has a straight-forward part which is waiting
for the thread to join and a complicated part which is doing a
qemu_file_shutdown() on the return path file.
The shutdown is tricky because all calls to qemu_file_shutdown() set
f->last_error to -EIO, which means we can never

Replace the return path retry logic with finishing and restarting the

segfault.
Currently when doing postcopy we consider that an IO error on the
return path file could be due to a network intermittency. We then keep

I used a wrong email account.
I also forgot to mention that you must update other places referring to
the Makefile. I'm aware of the following:
- root Makefile
- tests/tcg/Makefile.target
- docs/devel/tcg-plugins.rst

Move the PRE_COPY and RUNNING state checks to helper functions.
This is in preparation for adding P2P VFIO migration support, where
these helpers will also test for PRE_COPY_P2P and RUNNING_P2P states.

Now that P2P support has been added to VFIO migration, allow migration
of multiple devices if all of them support P2P migration.
Single device migration is allowed regardless of P2P migration support.

Changing the device state from STOP_COPY to STOP can take time as the
device may need to free resources and do other operations as part of the
transition. Currently, this is done in vfio_save_complete_precopy() and
therefore it is counted in the migration downtime.
To avoid this, change the

Hi all,
The first patch in this series adds a small optimization to VFIO
migration by moving the STOP_COPY->STOP transition to
vfio_save_cleanup(). Testing with a ConnectX-7 VFIO device showed that
this can reduce downtime by up to 6%.
The rest of the series adds P2P support for VFIO migration.
