Hi Rorie, Antony,
Note that there are corresponding QEMU patches that will be shipped
along
with this patch (see vfio-ap: Report vfio-ap configuration changes)
that
will pick up the eventfd signal.
How this patch is synchronized with the mentioned QEMU series?
What is the series status, especially with the comment from Cédric Le
Goater [1]?

Thanks!
Hey Alex, sorry for the long delay. This patch is synchronized with
the QEMU series by registering an event notifier handler to process AP
configuration
change events. This is done by queuing the event and generating a CRW.
The series status is currently going through a v2 RFC after
implementing changes
requested by Cedric and Tony.
Let me know if there's anything else you're concerned with
Thanks!
I don't think that is what Alex was asking. I believe he is asking how
the QEMU and kernel patch series are going to be synchronized.
Given the kernel series changes a value in vfio.h which is used by QEMU,
the two series need to be coordinated since the vfio.h file
used by QEMU can not be updated until the kernel code is available. So
these two sets of code have
to be merged upstream during a merge window. which is different for the
kernel and QEMU. At least I think that is what Alex is asking.
