[PATCH 3/3] sched, fair: Stop searching for tasks in newidle balance if there are runnable tasks

2014-04-23 Thread Jason Low
It was found that when running some workloads (such as AIM7) on large systems with many cores, CPUs do not remain idle for long. Thus, tasks can wake/get enqueued while doing idle balancing. In this patch, while traversing the domains in idle balance, in addition to checking for pulled_task, we

Commit e5fc6611 can potentially cause rq->max_idle_balance_cost to not be updated, even when load_balance(NEWLY_IDLE) is attempted and the per-sd max cost value is updated. In this patch, we update the rq->max_idle_balance_cost regardless of whether or not a task has been enqueued while browsing
