Subject: [PATCH 1/6] tools/perf/json: Add common metrics for s390
Date: Mon, 13 Mar 2023 09:01:56 +0100 [thread overview]
Message-ID: <20230313080201.2440201-1-tmricht@linux.ibm.com> (raw)
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:
https://www.ibm.com/support/pages/system/files/inline-files/CPU%20MF%20Formulas%20including%20z16%20-%20May%202022_1.pdf
Outpuf after:
# ./perf stat -M cpi -- dd if=/dev/zero of=/dev/null bs=1M count=10K
