Ok, I see there's guest_cpuid_is_amd() but I'd need also family and model.
How about adding also
guest_cpuid_family(), guest_cpuid_model(), guest_cpuid_stepping()? Those
could be quite useful in other contexts maybe.
Or, I can do a single function which simply returns CPUID_1_EAX of the
guest vcpu and caller can then pick stuff apart...
Thoughts?
