[PATCH OLK-5.10 1/2] sched/dynamic_affinity: fix preffered_cpu offline problem
by Xiangwei Li 23 Apr '25

23 Apr '25

From: He Yujie <coka.heyujie(a)huawei.com> Offering: HULK hulk inclusion category: bugfix bugzilla: 190373 -------------------------------- After the preferred_cpu goes offline, the core selection of dynamic affinity does not check whether the preferred_cpu is valid. As a result, related dynamic affinity processes are concentrated on a shared_cpu. This patch resolves this problem to checks whether the preferred_cpu is valid and compares only the usage threshold of the valid preferred_cpu.
