Re: [EXTERNAL] Re: [RFC PATCH v1] powerpc/prom_init: disable XIVE in Secure VM.

**** BTW: I figured, I dont need this intermin patch to disable xive for
secure VM.  Just doing "svm=on xive=off" on the kernel command line is
sufficient for now. *****

No it is not. If the hypervisor doesn't propose XIVE (ie. ic-mode=xive
on the QEMU command line), the kernel simply ignores "xive=off".

If I am correct, with the option ic-mode=xive, the hypervisor will 
propose only 'xive' in OV5 and not both 'xive' and 'xics'. But the
result is the same because xive can not be turned off and "xive=off" 
is ignored.

Anyway, it's not the most common case of usage of the QEMU command
like. I think it's OK to use "xive=off" on the kernel command line 
for now.
