Power aware scheduling needs the cpu topology information to improve the cpu scheduler decision making.
It's not only power aware scheduling. The scheduler already uses topology and cache sharing when CONFIG_SCHED_MC and/or CONFIG_SCHED_SMT are enable. So you should also add these configs for arm64 so the scheduler can use it
Just for my knowledge, I thought power aware using SCHED_MC/SMT was removed. I see commit 8e7fbcbc22c12414bcc9dfdd683637f58fb32759 "sched: Remove stale power aware scheduling remnants and dysfunctional knobs" I may be missing something here.
