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: https://www.ibm.com/support/pages/system/files/inline-files/CPU%20MF%20Formulas%20including%20z16%20-%20May%202022_1.pdf Output after: # ./perf stat -M cpi -- dd if=/dev/zero of=/dev/null bs=1M count=10K 10240+0 records in 10240+0 records out 10737418240 bytes (11 GB, 10 GiB) copied, 1.30151 s, 8.2 GB/s Performance counter stats for 'dd if=/dev/zero of=/dev/null .....': 6,779,778,802 CPU_CYCLES # 1.96 cpi 3,461,975,090 INSTRUCTIONS 1.306873021 seconds time elapsed 0.001034000 seconds user 1.305677000 seconds sys # Signed-off-by: Thomas Richter <tmricht@linux.ibm.com> Acked-by: Ian Rogers <irogers@google.com> Acked-By: Sumanth Korikkar <sumanthk@linux.ibm.com> Cc: Heiko Carstens <hca@linux.ibm.com> Cc: Sven Schnelle <svens@linux.ibm.com> Cc: Vasily Gorbik <gor@linux.ibm.com> Link: https://lore.kernel.org/r/20230313080201.2440201-1-tmricht@linux.ibm.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
