5 Performance counters are special hardware registers available on most modern
13 hardware capabilities. It provides per task and per CPU counters, counter
16 underlying hardware counters.
78 If 'raw_type' is 1, then the counter will count a hardware event
91 A counter of PERF_TYPE_HARDWARE will count the hardware event
