It's trivial to recalculate in a user-space tool, and the Is it trivial to recalculate that in a userspace tool? I thought the only way to properly calculate that in the first place was to use cpuid_eax() in the calculation, which is only available at hypervisor level (hence much of this thread).

Unfortunately, due to the design of components I don't control, my application does not have the luxury of waiting for an MSR write event. (Has my MSR mem_event patch been acknowledged? Or was this already work in progress? I had to patch my Xen source code to be able to get MSR events...) > I'll take a proper look at this thread tomorrow and see if I can suggest > anything more helpful. Thank you, I appreciate the reply, and your time.
