[PATCH OLK-5.10 V1] sched/fair: Scan cluster before scanning LLC in try_steal path
by Cheng Yu 07 Aug '24

07 Aug '24

If we enable the STEAL feature, when the newidle_balance fails, it will first find the busy CPU from the same smt, and then the same LLC. This patch makes the following modifications: the same cluster will be scanned before LLC. Thus, we can use more memory bandwidth.
