This in term can reduce sampling overhead and the size of the perf.data. Changes since V1: - Break up V1 patches into three patches(parse option changes, partial time support and partial callgraph support). - Use strings 'fp,dwarf,lbr,no' to identify callchains - Add test case in parse-events.c Changes since V2: - Rebase on 60cd37eb10 Changes since V3: - Replace OPT_CALLBACK_SET by current existing callback mechanism. - Using perf_evsel__set_sample_bit if possible - Change the expression "partial" to "per event" - Using global variable to indicate if 'time' is set per event. If 'time' is not set, enable it by default for perf record. Changes since V4: - Fix issue of setting callgraph_set Changes since V5: - per-event settings over global settings in general - support for event post configuration structure Changes since V6: - Add error infor for per-event time - rename the option to call-graph and stacl-size - refine parse/config callchain functions, and reuse them for per-event callgraph setting - Modify perf test Jiri Olsa (2): perf tools: Add support for event post configuration perf tools: Force period term to overload global settings Kan Liang (5): perf,tools: introduce callgraph_set for callgraph option perf,tools: per-event time support perf,tools: refine parse/config callchain functions perf,tools: per-event callgraph support perf,tests: Add tests to callgraph and time parse tools/perf/Documentation/perf-record.txt | 10 ++- tools/perf/builtin-record.c | 11 +++- tools/perf/perf.h | 1 + tools/perf/tests/parse-events.c | 50 ++++++++++++++- tools/perf/util/callchain.c | 14 ++--- tools/perf/util/callchain.h | 2 +- tools/perf/util/evsel.c | 105 +++++++++++++++++++++++++++++-- tools/perf/util/evsel.h | 26 ++++++++ tools/perf/util/parse-events.c | 94 +++++++++++++++++++++++---- tools/perf/util/parse-events.h | 3 + tools/perf/util/parse-events.l | 3 + tools/perf/util/pmu.c | 3 +- 12 files changed, 289 insertions(+), 33 deletions(-) -- 1.8.3.1 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
