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. C.
