CPUs support APIC virtualization

CPUs support APIC virtualization

[Arthur Chunqi Li]

Hi there,

I have noticed in Intel SDM that some kinds of CPUs support APIC
virtualization (e.g. Virtual-interrupt delivery). I checked all my
Intel CPUs' MSR and found none of them support this. So do anybody
know which types of Intel CPU supports APIC virtualization? Or where
can I get related information?

Thanks,
Arthur

This article metioned that the latest Intel(R) Xeon(R) processors, such
as the Intel(R) Xeon(R) E5-2600 v2 Product Family, emulate those
activities in the hardware.
