I would like to know how what perf counters describe remote memory loads from other cores or nodes. The Arm Cortex A-Series, Programmer's Guide for Arm v8-a (https://cs140e.sergio.bz/docs/ARMv8-A-Programmer-Guide.pdf, would be nice to know the official link to that document too)says (at 11-7):
> For multi-core and multi-cluster systems, before performing a load from external memory, the caches of L2 or L1 caches of cores within the cluster or of other clusters might also be checked
What perf counters describe such loads?
