Add a perf PMU to access the CPU-measurement counter facility CPUM CF.
CPUM CF provides multiple counter sets for measuring generic,
problem-state, and crypto activaties. Also an extended counter set for
the IBM System z10 and IBM z196 mainframes is available.
Counters from the basic and problem-state counter set are mapped to
generic perf hardware events. Other counters are accessible through
raw events.
For a list of available counter sets and counters, see:
- The Load-Program-Parameter and the CPU-Measurement Facilities (SA23-2260)
- The CPU-Measurement Facility Extended Counters Definition for
z10 and z196 (SA23-2261)
