- * Each counter consists of the counter id, hardware thread id, and the count
- * itself; each counter can be assigned to multiple hardware threads at any
- * one time, with the returned count being an aggregate of events. A small
- * number of events are thread global, i.e. they count the aggregate of all
- * threads' events, regardless of the thread selected.
- *
- * Newer cores can store an arbitrary 24-bit number in the counter, whereas
