Configure the minimum demand of big sync waker task. Scheduler places small wakee tasks woken up by big sync waker on the waker's cluster. +*** 7.19 sched_prefer_sync_wakee_to_waker + +Appears at: /proc/sys/kernel/sched_prefer_sync_wakee_to_waker + +Default value: 0 + +The default sync wakee policy has a preference to select an idle CPU in the +waker cluster compared to the waker CPU running only 1 task. By selecting +an idle CPU, it eliminates the chance of waker migrating to a different CPU +after the wakee preempts it. This policy is also not susceptible to the +incorrect "sync" usage i.e the waker does not goto sleep after waking up +the wakee. + +However LPM exit latency associated with an idle CPU outweigh the above +benefits on some targets.
