POWER9 support will come with QEMU 2.10. Sam, could you please confirm which commit IDs, if any, are needed for this feature? I think that maybe in this case it is just a set of KVM patches actually that provides all the needed support for POWER9. ------- Comment From [email protected] 2017-05-23 12:23 EDT------- (In reply to comment #5) > Hi, > especially for new features I assume that you'll do the testing, but some > sort of extra info on ... > > a) what it does XICS is the interrupt controler on POWER8. So, if you are using a guest on POWER8-compat mode, it will use XICS instead of XIVE (the POWER9 interrupt controller).
