[Detail] Big task rotation swap current task between big cores and little cores, it could upgrade multi-core scores. If conform following condition, start big task rotation: 1. Enable big task rotation 2. little core has misfit task 3. find same capacity core fit this misfit task 4. number of misfit rq >= 4 Enable big task rotation: echo 1 > /proc/sys/kernel/sched_big_task_rotation MTK-Commit-Id: 62bb741cc5c6fc43540681f8b54e32dc652d99de Change-Id: Iebe785359a63ae06b8412cb54150fa58d8ebe160 CR-Id:ALPS04201050 Feature:Energy Aware Scheduling Plus (EAS+) Signed-off-by: Jing-Ting Wu <jing-ting.wu@mediatek.com> (cherry-pick from 4f80d6239e8179e3f64ff8551cae411c15fdad51)
