This is caused by the CPU\nstring saved in the mapfile.csv for this machine:\n\n ^IBM.393[12].*3\\.7.[[:xdigit:]]+$,3,cf_z16,core\n\nThis string contains the CPU Measurement facility first and second\nversion number and authorization level (3\\.7.[[:xdigit:]]+). These\nnumbers do not apply to the PAI counter facility. In fact they can be\nomitted.\n\nShorten the CPU identification string for this machine to manufacturer\nand model. This is sufficient for all PMU devices.\n\nOutput after:\n\n # perf report -i /tmp//perfout-635468 -D | grep Counter\n\tCounter:007 km_aes_128 Value:0x00000000000186a0\n\tCounter:032 kma_gcm_aes_256 Value:0x0000000000000001\n\tCounter:032 kma_gcm_aes_256 Value:0x0000000000000001\n\tCounter:032 kma_gcm_aes_256 Value:0x0000000000000001\n #\n\nFixes: b539deafbadb2fc6 (\"perf report: Add s390 raw data interpretation for PAI counters\")\nReviewed-by: Ian Rogers <irogers@google.com>\nSigned-off-by: Thomas Richter <tmricht@linux.ibm.com>\nAcked-by: Sumanth Korikkar <sumanthk@linux.ibm.com>\nCc: Heiko Carstens <hca@linux.ibm.com>\nCc: Namhyung Kim <namhyung@kernel.org>\nCc: Sven Schnelle <svens@linux.ibm.com>\nCc: Thomas Richter <tmricht@linux.ibm.com>\nCc: Vasily Gorbik <gor@linux.ibm.com>\nLink: https://lore.kernel.org/r/20240404064806.1362876-1-tmricht@linux.ibm.com\nSigned-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>\n(cherry picked from commit b74bc5a633a7d72f89141d481d835e73bda3c3ae)\nSigned-off-by: Massimiliano Pellizzer <massimiliano.pellizzer@canonical.com>\n---\n tools/perf/pmu-events/arch/s390/mapfile.csv | 2 +-\n 1 file changed, 1 insertion(+), 1 deletion(-)", "diff": "diff --git a/tools/perf/pmu-events/arch/s390/mapfile.csv b/tools/perf/pmu-events/arch/s390/mapfile.csv\nindex a918e1af77a5..b22648d12751 100644\n--- a/tools/perf/pmu-events/arch/s390/mapfile.csv\n+++ b/tools/perf/pmu-events/arch/s390/mapfile.csv\n@@ -5,4 +5,4 @@ Family-model,Version,Filename,EventType\n ^IBM.296[45].*[13]\\.[1-5].[[:xdigit:]]+$,1,cf_z13,core\n ^IBM.390[67].*[13]\\.[1-5].[[:xdigit:]]+$,3,cf_z14,core\n ^IBM.856[12].*3\\.6.[[:xdigit:]]+$,3,cf_z15,core\n-^IBM.393[12].*3\\.7.[[:xdigit:]]+$,3,cf_z16,core\n+^IBM.393[12].*$,3,cf_z16,core\n", "prefixes": [ "SRU", "J", "11/12" ] }
