Patchset adds json file metric support for the hv_24x7 socket/chip level events. "hv_24x7" pmu interface events needs system dependent parameter like socket/chip/core. For example, hv_24x7 chip level events needs specific chip-id to which the data is requested should be added as part of pmu events. So to enable JSON file support to "hv_24x7" interface, patchset expose total number of sockets and chips per-socket details in sysfs files (sockets, chips) under "/sys/devices/hv_24x7/interface/". To get sockets and number of chips per sockets, patchset adds a rtas call with token "PROCESSOR_MODULE_INFO" to get these details. Patchset also handles partition migration case to re-init these system depended parameters by adding proper calls in post_mobility_fixup() (mobility.c). Patch 6 & 8 of the patchset handles perf tool plumbing needed to replace the "?" character in the metric expression to proper value and hv_24x7 json metric file for different Socket/chip resources. Patch set also enable Hz/hz prinitg for --metric-only option to print metric data for bus frequency. Applied and tested all these patches cleanly on top of jiri's flex changes patchset and made required changes. Changelog: v2 -> v3 - Remove setting event_count to 0 part in function 'h_24x7_event_read' with comment rather then adding 0 to event_count value. Suggested by: Sukadev Bhattiprolu - Apply tool side changes require to replace "?" on Jiri's flex patch series and made all require changes to make it compatible with added flex change. v1 -> v2 - Rename hv-24x7 metric json file as nest_metrics.json Kajol Jain (8): powerpc/perf/hv-24x7: Fix inconsistent output values incase multiple hv-24x7 events run powerpc/hv-24x7: Add rtas call in hv-24x7 driver to get processor details powerpc/hv-24x7: Add sysfs files inside hv-24x7 device to show processor details Documentation/ABI: Add ABI documentation for chips and sockets powerpc/hv-24x7: Update post_mobility_fixup() to handle migration perf/tools: Enhance JSON/metric infrastructure to handle "?" tools/perf: Enable Hz/hz prinitg for --metric-only option perf/tools/pmu-events/powerpc: Add hv_24x7 socket/chip level metric events .../sysfs-bus-event_source-devices-hv_24x7 | 14 +++ arch/powerpc/perf/hv-24x7.c | 104 ++++++++++++++-- arch/powerpc/platforms/pseries/mobility.c | 12 ++ arch/powerpc/platforms/pseries/pseries.h | 3 + tools/perf/arch/powerpc/util/header.c | 47 ++++++++ .../arch/powerpc/power9/nest_metrics.json | 19 +++ tools/perf/util/expr.h | 1 + tools/perf/util/expr.l | 18 ++- tools/perf/util/expr.y | 2 + tools/perf/util/metricgroup.c | 112 +++++++++++------- tools/perf/util/metricgroup.h | 1 + tools/perf/util/stat-display.c | 2 - tools/perf/util/stat-shadow.c | 6 + 13 files changed, 286 insertions(+), 55 deletions(-) create mode 100644 tools/perf/pmu-events/arch/powerpc/power9/nest_metrics.json -- 2.21.0
