The PMUs on the Apple M2 cores avalanche and blizzard CPU are compatible with M1 ones. As on M1 we don't know exactly what the counters count so use a distinct compatible for each micro-architecture. Apple's PMU counter description omits a counter for M2 so there is some variation on the interpretation of the counters.
