It doesn't look like any of the composite ports actually map directly to the counters?

Can you clarify what you mean by this? As in differentiating between different microarchitectures on the same platform? I don't believe there is any support for doing that currently. There also isn't any support for CPU affinity masks either, but https://github.com/llvm/llvm-project/pull/85168 might get the ball rolling on that.
