The hv_24×7 feature in IBM® POWER9™ processor-based servers provide the facility to continuously collect large numbers of hardware performance metrics efficiently and accurately. This patch adds hv_24x7 json metric file for different Socket/chip resources. Result: power9 platform: command:# ./perf stat --metric-only -M Memory_RD_BW_Chip -C 0 -I 1000 sleep 1 time MB Memory_RD_BW_Chip_0 MB Memory_RD_BW_Chip_1 MB 1.000192635 0.4 0.0 1.001695883 0.0 0.0 Signed-off-by: Kajol Jain <redacted> --- .../arch/powerpc/power9/hv_24x7_metrics.json | 19 +++++++++++++++++++ 1 file changed, 19 insertions(+) create mode 100644 tools/perf/pmu-events/arch/powerpc/power9/hv_24x7_metrics.jsondiff --git a/tools/perf/pmu-events/arch/powerpc/power9/hv_24x7_metrics.json b/tools/perf/pmu-events/arch/powerpc/power9/hv_24x7_metrics.json new file mode 100644 index 000000000000..ac38f5540ac6 --- /dev/null +++ b/tools/perf/pmu-events/arch/powerpc/power9/hv_24x7_metrics.json
Better to have it as nest_metrics.json instead. Rest looks fine Reviewed-by: Madhavan Srinivasan <maddy@linux.ibm.com>
