The Solaris cpc(3CPC) subsystem implements a number of predefined, generic performance counter events. Each generic event maps onto a single platform specific event and one or more optional attributes. Each hardware platform only need support a subset of the total set of generic events.
The defined generic events are: PAPI_br_cn
Conditional branch instructions
Branch instructions taken
Conditional branch instructions mispredicted
Conditional branch instructions not taken
Conditional branch instructions correctly predicted
Unconditional branch instructions
Cycles branch units are idle
Branch target address cache misses

Requests for cache invalidation
Requests for cache line intervention
Request for exclusive access to shared cache line
Request for cache snoop
