The following commit has been merged into the sched/core branch of tip: Commit-ID: ed74cc4995d314ea6cbf406caf978c442f451fa5 Gitweb: https://git.kernel.org/tip/ed74cc4995d314ea6cbf406caf978c442f451fa5 Author: Peter Zijlstra <peterz@infradead.org> AuthorDate: Fri, 07 Jul 2023 15:57:05 -07:00 Committer: Peter Zijlstra <peterz@infradead.org> CommitterDate: Thu, 13 Jul 2023 15:21:53 +02:00 sched/debug: Dump domains' sched group flags There have been a case where the SD_SHARE_CPUCAPACITY sched group flag in a parent domain were not set and propagated properly when a degenerate domain is removed. Add dump of domain sched group flags of a CPU to make debug easier in the future. Usage: cat /debug/sched/domains/cpu0/domain1/groups_flags to dump cpu0 domain1's sched group flags.
