[Qemu-devel] [PATCH] hw/ppc/spapr: Allow POWER9 as hot-pluggable CPU for pseries

[Qemu-devel] [PATCH] hw/ppc/spapr: Allow POWER9 as hot-pluggable CPU for pseries

[Thomas Huth]

Running "qemu-system-ppc64 -M pseries -cpu POWER9" currently does not work
yet and results in this error message:

 qemu-system-ppc64: Unable to find sPAPR CPU Core definition

Since we want to support the pseries machine with POWER9 in the future,
allow using POWER9 as hot-pluggable CPU there, too.

I'm not sure it makes sense to apply this until we have at least the
basics of the POWER9 PAPR pieces implemented in qemu.

OK, then I'll keep it in my private branch for my experiments...
