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). Second patch of the patchset adds expr_scanner_ctx object to hold user data for the expr scanner, which can be used to hold runtime parameter. Patch 9 & 11 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 with the changes done by Kan Liang for "Support metric group constraint" patchset and made required changes. Changelog: v5 -> v6 - resolve compilation issue due to rearranging patch series. - Rather then adding new function to take careof case for runtime param in metricgroup__add_metric, using metricgroup__add_metric_param itself for that work. - Address some optimization suggested like using directly file path rather then adding new macro in header.c - Change commit message on patch where we are adding "?" support by adding simple example. v4 -> v5 - Using sysfs__read_int instead of sysfs__read_ull while reading parameter value in powerpc/util/header.c file. - Using asprintf rather then malloc and sprintf Suggested by Arnaldo Carvalho de Melo - Break patch 6 from previous version to two patch, - One to add refactor current "metricgroup__add_metric" function and another where actually "?" handling infra added. - Add expr__runtimeparam as part of 'expr_scanner_ctx' struct rather then making it global variable. Thanks Jiri for adding this structure to hold user data for the expr scanner. - Add runtime param as agrugement to function 'expr__find_other' and 'expr__parse' and made changes on references accordingly. v3 -> v4 - Apply these patch on top of Kan liang changes. As suggested by Jiri. 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 Jiri Olsa (2): perf expr: Add expr_ prefix for parse_ctx and parse_id perf expr: Add expr_scanner_ctx object Kajol Jain (9): 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: Refactoring metricgroup__add_metric function 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 | 8 ++ .../arch/powerpc/power9/nest_metrics.json | 19 ++++ tools/perf/tests/expr.c | 12 +- tools/perf/util/expr.c | 25 +++-- tools/perf/util/expr.h | 19 ++-- tools/perf/util/expr.l | 37 +++++-- tools/perf/util/expr.y | 6 +- tools/perf/util/metricgroup.c | 88 +++++++++++---- tools/perf/util/metricgroup.h | 1 + tools/perf/util/stat-display.c | 2 - tools/perf/util/stat-shadow.c | 14 ++- 15 files changed, 287 insertions(+), 77 deletions(-) create mode 100644 tools/perf/pmu-events/arch/powerpc/power9/nest_metrics.json -- 2.18.1
