[PATCH 5/5] sched: SIS_CORE to disable idle core search

2018-06-28 Thread subhra mazumdar
Use SIS_CORE to disable idle core search. For some workloads select_idle_core becomes a scalability bottleneck, removing it improves throughput. Also there are workloads where disabling it can hurt latency, so need to have an option. Signed-off-by: subhra mazumdar --- kernel/sched/fair.c | 8 +++
