The following series of patches enable KVM to exploit the hardware
hypervisor mode on 64-bit Power ISA Book3S machines.  At present,
POWER7 and PPC970 processors are supported.  (Note that the PPC970
processors in Apple G5 machines don't have a usable hypervisor mode
and are not supported by these patches.)
I have a Maple board (dual PPC970FX). Will this patchset work on it?
Should I add any additional changes to add support for this platform?

Thanks!

Provided the firmware gives you control in hypervisor mode, yes it
should work, and I don't know of any extra changes you would need.
I don't recall what firmware the Maple boards had on them, though.

I think it's more specifically whether the FW of the service processor
configure the mode rings of the 970 to "Apple" mode or not.

Cheers,

On my board I have a PIBS firmware which programs all PPC970 registers
with special script. I think one of the scripts bears "hypervisor" settings,
so I'll try to give this patchset a try.
