sched/fair: SIS improvements and cleanups

[PATCH 0/5] sched/fair: SIS improvements and cleanups

Posted by Abel Wu 3 years, 9 months ago

The first patch ignores the new sched_feat SIS_UTIL when
there are idle cores available to make full use of cpus
as possible.

The other patches come from the SIS filter patchset [1],
since they are irrelevant to the filter.

Abel Wu (5):
  sched/fair: ignore SIS_UTIL when has idle core
  sched/fair: default to false in test_idle_cores
  sched/fair: remove redundant check in select_idle_smt
  sched/fair: avoid double search on same cpu
  sched/fair: remove useless check in select_idle_core
