MONITOR/MWAIT without VM-exits in a VMX guest

383 Views

Hi,

I'm looking for an intel CPU where VMX supports MONITOR/MWAIT on the guest without VM-exits (*). As far as I understand, my Haswell CPU does not support this feature, and I've been unable to find any source of information that can tell me which of Intel's CPU microarchitectures supports this feature.

Does such a list exist somewhere, or does anyone know when Intel CPUs started supporting this feature?

(*) I.e., bit "MONITOR exiting" can be set to zero in the "Processor-Based VM-Execution Controls", which is announced accordingly on the IA32_VMX_PROCBASED_CTLS MSR.

Thanks,

Lluís
