From 74395567a3011a07f51cf959be96c1eecb3e6df8 Mon Sep 17 00:00:00 2001 From: Thomas Richter Date: Mon, 13 Mar 2023 09:01:56 +0100 Subject: [PATCH] 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 Acked-by: Ian Rogers Acked-By: Sumanth Korikkar Cc: Heiko Carstens Cc: Sven Schnelle Cc: Vasily Gorbik Link: https://lore.kernel.org/r/20230313080201.2440201-1-tmricht@linux.ibm.com Signed-off-by: Arnaldo Carvalho de Melo --- tools/perf/pmu-events/arch/s390/cf_z13/transaction.json | 15 +++++++++++++++ tools/perf/pmu-events/arch/s390/cf_z14/transaction.json | 15 +++++++++++++++ tools/perf/pmu-events/arch/s390/cf_z15/transaction.json | 15 +++++++++++++++ tools/perf/pmu-events/arch/s390/cf_z16/transaction.json | 15 +++++++++++++++ 4 files changed, 60 insertions(+) diff --git a/tools/perf/pmu-events/arch/s390/cf_z13/transaction.json b/tools/perf/pmu-events/arch/s390/cf_z13/transaction.json index 1a0034f..86bf83b 100644 --- a/tools/perf/pmu-events/arch/s390/cf_z13/transaction.json +++ b/tools/perf/pmu-events/arch/s390/cf_z13/transaction.json @@ -3,5 +3,20 @@ "BriefDescription": "Transaction count", "MetricName": "transaction", "MetricExpr": "TX_C_TEND + TX_NC_TEND + TX_NC_TABORT + TX_C_TABORT_SPECIAL + TX_C_TABORT_NO_SPECIAL" + }, + { + "BriefDescription": "Cycles per Instruction", + "MetricName": "cpi", + "MetricExpr": "CPU_CYCLES / INSTRUCTIONS" + }, + { + "BriefDescription": "Problem State Instruction Ratio", + "MetricName": "prbstate", + "MetricExpr": "(PROBLEM_STATE_INSTRUCTIONS / INSTRUCTIONS) * 100" + }, + { + "BriefDescription": "Level One Miss per 100 Instructions", + "MetricName": "l1mp", + "MetricExpr": "((L1I_DIR_WRITES + L1D_DIR_WRITES) / INSTRUCTIONS) * 100" } ] diff --git a/tools/perf/pmu-events/arch/s390/cf_z14/transaction.json b/tools/perf/pmu-events/arch/s390/cf_z14/transaction.json index 1a0034f..86bf83b 100644 --- a/tools/perf/pmu-events/arch/s390/cf_z14/transaction.json +++ b/tools/perf/pmu-events/arch/s390/cf_z14/transaction.json @@ -3,5 +3,20 @@ "BriefDescription": "Transaction count", "MetricName": "transaction", "MetricExpr": "TX_C_TEND + TX_NC_TEND + TX_NC_TABORT + TX_C_TABORT_SPECIAL + TX_C_TABORT_NO_SPECIAL" + }, + { + "BriefDescription": "Cycles per Instruction", + "MetricName": "cpi", + "MetricExpr": "CPU_CYCLES / INSTRUCTIONS" + }, + { + "BriefDescription": "Problem State Instruction Ratio", + "MetricName": "prbstate", + "MetricExpr": "(PROBLEM_STATE_INSTRUCTIONS / INSTRUCTIONS) * 100" + }, + { + "BriefDescription": "Level One Miss per 100 Instructions", + "MetricName": "l1mp", + "MetricExpr": "((L1I_DIR_WRITES + L1D_DIR_WRITES) / INSTRUCTIONS) * 100" } ] diff --git a/tools/perf/pmu-events/arch/s390/cf_z15/transaction.json b/tools/perf/pmu-events/arch/s390/cf_z15/transaction.json index 1a0034f..86bf83b 100644 --- a/tools/perf/pmu-events/arch/s390/cf_z15/transaction.json +++ b/tools/perf/pmu-events/arch/s390/cf_z15/transaction.json @@ -3,5 +3,20 @@ "BriefDescription": "Transaction count", "MetricName": "transaction", "MetricExpr": "TX_C_TEND + TX_NC_TEND + TX_NC_TABORT + TX_C_TABORT_SPECIAL + TX_C_TABORT_NO_SPECIAL" + }, + { + "BriefDescription": "Cycles per Instruction", + "MetricName": "cpi", + "MetricExpr": "CPU_CYCLES / INSTRUCTIONS" + }, + { + "BriefDescription": "Problem State Instruction Ratio", + "MetricName": "prbstate", + "MetricExpr": "(PROBLEM_STATE_INSTRUCTIONS / INSTRUCTIONS) * 100" + }, + { + "BriefDescription": "Level One Miss per 100 Instructions", + "MetricName": "l1mp", + "MetricExpr": "((L1I_DIR_WRITES + L1D_DIR_WRITES) / INSTRUCTIONS) * 100" } ] diff --git a/tools/perf/pmu-events/arch/s390/cf_z16/transaction.json b/tools/perf/pmu-events/arch/s390/cf_z16/transaction.json index 1a0034f..86bf83b 100644 --- a/tools/perf/pmu-events/arch/s390/cf_z16/transaction.json +++ b/tools/perf/pmu-events/arch/s390/cf_z16/transaction.json @@ -3,5 +3,20 @@ "BriefDescription": "Transaction count", "MetricName": "transaction", "MetricExpr": "TX_C_TEND + TX_NC_TEND + TX_NC_TABORT + TX_C_TABORT_SPECIAL + TX_C_TABORT_NO_SPECIAL" + }, + { + "BriefDescription": "Cycles per Instruction", + "MetricName": "cpi", + "MetricExpr": "CPU_CYCLES / INSTRUCTIONS" + }, + { + "BriefDescription": "Problem State Instruction Ratio", + "MetricName": "prbstate", + "MetricExpr": "(PROBLEM_STATE_INSTRUCTIONS / INSTRUCTIONS) * 100" + }, + { + "BriefDescription": "Level One Miss per 100 Instructions", + "MetricName": "l1mp", + "MetricExpr": "((L1I_DIR_WRITES + L1D_DIR_WRITES) / INSTRUCTIONS) * 100" } ] -- 2.7.4
