in this particular case we can clearly separate the two workloads though: CPU-overload (Ken's benchmark) vs. half-load (3-task tbench). So by checking for migration target/source idleness we can have a hard separator for wakeup balancing. (whether it works out for both types of workloads remains to be seen) Ingo - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
