Hi, This is my second attempt to support event group on perf report. For basic idea and usage example, please see my original post [1].
The main difference than v1 is adding HEADER_GROUP_DESC feature and use it for regenerating group relationship on perf report. It will save actual (i.e. contains non-leader member) group information to perf header. Patch 1 is a bug fix which can be applied indenpedently. Patch 2-4 are cleanups to facilitate later changes and came from my cumulative report series [2]. You can also access it via my tree at: git://git.kernel.org/pub/scm/linux/kernel/git/namhyung/linux-perf.git perf/group-v2 Any comments are welcome, thanks, Namhyung v1 -> v2: * save group relation to header (Jiri) * rebase on top of current acme/perf/core [1] https://lkml.org/lkml/2012/7/24/81 [2] https://lkml.org/lkml/2012/9/13/81 Namhyung Kim (16): perf hists: Add missing period_* fields when collapsing a hist entry perf hists: Introduce struct he_stat perf hists: Move he->stat.nr_events initialization to a template perf hists: Add more helpers for hist entry stat perf tools: Keep group information perf evlist: Add perf_evlist__recalc_nr_groups perf header: Add HEADER_GROUP_DESC feature perf hists: Collapse group hist_entries to a leader perf hists: Maintain total periods of group members in the leader perf report: Make another loop for output resorting perf ui/hist: Add support for event group view perf ui/browser: Add support for event group view perf ui/gtk: Add support for event group view perf report: Bypass non-leader events when event group is enabled perf report: Show group description when event group is enabled perf report: Add --group option tools/perf/builtin-record.c | 6 ++ tools/perf/builtin-report.c | 29 +++++++ tools/perf/ui/browsers/hists.c | 107 ++++++++++++++++++++--- tools/perf/ui/gtk/browser.c | 70 ++++++++++++--- tools/perf/ui/hist.c | 104 +++++++++++++++++------ tools/perf/ui/stdio/hist.c | 4 +- tools/perf/util/evlist.c | 26 +++++- tools/perf/util/evlist.h | 2 + tools/perf/util/evsel.c | 25 ++++++ tools/perf/util/evsel.h | 23 +++++ tools/perf/util/header.c | 149 ++++++++++++++++++++++++++++++++ tools/perf/util/header.h | 2 + tools/perf/util/hist.c | 188 +++++++++++++++++++++++++++++++++++------ tools/perf/util/hist.h | 2 + tools/perf/util/parse-events.c | 1 + tools/perf/util/parse-events.h | 1 + tools/perf/util/parse-events.y | 4 + tools/perf/util/sort.h | 17 ++-- tools/perf/util/symbol.c | 4 + tools/perf/util/symbol.h | 3 +- 20 files changed, 683 insertions(+), 84 deletions(-) -- 1.7.11.4 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
