While working on a paravirt cpuidle driver for KVM guests, I noticed a number of small logic errors in the menu governor code.
These patches should get rid of some artifacts that can break the logic in the menu governor under certain corner cases, and make idle state selection work better on CPUs with long C1 exit latencies. I have not seen any adverse effects with them in my (quick) tests. As expected, they do not seem to do much on systems with many power states and very low C1 exit latencies and target residencies. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
