OTOH, it has to be long enough to enter a package idle state and stay there for a while. You would surely notice it when it kicks in on an Android device. Do you intend to use it only as a last option? One might want to keep using inefficient frequencies (P-states) if those don't cause UI lag then. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
