perf vendor events s390: Add common metrics
Add 3 metrics for s390 machines:
- Cycles per instruction: Amount of CPU cycles used per instructions,
named cpi.
- Problem state ratio: Ratio of instructions executed in problem state
compared to total number of instructions, named prbstate.
- Level one instruction and data cache misses per 100 instructions,
named l1mp.
For details about the formulas see this documentation:
