Can you please consider to provide an example of such counters being
used, i.e. with a simple C synthetic test that causes these events to
take place, then run it via 'perf stat' to show that indeed, they are
being programmed and read correctly?

Ideally for all of them, but if that becomes too burdensome, for a few
of them?

Thanks,

- Arnaldo
