Until then, the QEMU support will have some documentation on the
hcalls and on the device tree.
I am still struggling with CAS on QEMU. POWER9 supports both the
legacy XICS model and the newer one, XIVE, and we can switch from
one another depending on the guest kernel. This is a serious
headache for the model as the ICS/ICP objects are chosen after
the guest has booted.
That will be a topic for some discussion on the qemu-ppc mailing
list. Hopefully soon.
