Could you elaborate on what you mean by "cluster based event"?

I assume you mean something like events for a cluster-affine shared
resource like some level of cache?

If so, there's a standard pattern for supporting such system/uncore
PMUs, see drivers/perf/qcom_l2_pmu.c and friends for examples.

Thanks,
