If I remember well, each XIVE subunit has a copy of the config registers and modifications to the CQ unit are spanned to the others.

QEMU has an avocado test : build/tests/venv/bin/avocado -t machine:pseries build/tests/avocado/boot_linux.py which hangs. More tests would be good to have.

The presenters for xive on P9 and P10 are mostly similar but the behavior can be tuned through a few CQ registers.
