From: Namhyung Kim <[email protected]> Add report.children config option for setting default value of callchain accumulation. It affects the report output only if perf.data contains callchain info.
A user can write .perfconfig file like below to enable accumulation by default: $ cat ~/.perfconfig [report] children = true And it can be disabled through command line: $ perf report --no-children Signed-off-by: Namhyung Kim <[email protected]> Tested-by: Arun Sharma <[email protected]> Tested-by: Rodrigo Campos <[email protected]> Cc: Frederic Weisbecker <[email protected]> Link: http://lkml.kernel.org/r/[email protected] Signed-off-by: Jiri Olsa <[email protected]> --- tools/perf/builtin-report.c | 4 ++++ 1 file changed, 4 insertions(+) diff --git a/tools/perf/builtin-report.c b/tools/perf/builtin-report.c index f27a8aa..6cac509 100644 --- a/tools/perf/builtin-report.c +++ b/tools/perf/builtin-report.c @@ -72,6 +72,10 @@ static int report__config(const char *var, const char *value, void *cb) rep->min_percent = strtof(value, NULL); return 0; } + if (!strcmp(var, "report.children")) { + symbol_conf.cumulate_callchain = perf_config_bool(var, value); + return 0; + } return perf_default_config(var, value, cb); } -- 1.8.3.1 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
