Does KVM *have* a concept of "maximum non-turbo frequency" of the guest that it would make sense to expose here? If so, presumably the right solution is to expose it.
KVM has the concept of a guest's invariant TSC frequency. The Maximum Non-Turbo Ratio is just some fraction of that. Sadly, the fraction is 100 MHz, 133.33MHz, or the "scalable bus frequency" from some other MSR, depending on microarchitecture. -- To unsubscribe from this list: send the line "unsubscribe linux-kselftest" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
