I think that means the PV interface for lapic. And yes, we can support it follow MS's interface, but x2apic still seems another story as you noted... I still don't think support x2apic here would bring us more benefits.
x2apic has the following benefit: - msr exits are faster than mmio (no page table walk, emulation) - no need to read back ICR to look at the busy bit - one ICR write instead of two - potential to support large guests once we add interrupt remapping - shared code with the Hyper-V paravirt interface -- error compiling committee.c: too many arguments to function -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
