Right now in the main cases of using wake_affine to achieve better performance, processes are actually bound within one numa which is also a LLC in kunpeng920.

Probably LLC=NUMA is also true for X86 Jacobsville, Tim?

In general for x86, LLC is partitioned at the sub-numa cluster level. LLC could be divided between sub-numa cluster within a NUMA node. That said, for Jacobsville, we don't have sub-numa clusters so LLC=NUMA is true for that platform.
