perf top: Add top.children config option
Add top.children config option for setting default value of callchain accumulation. It affects the output only if one of -g or --call-graph option is given as well. A user can write .perfconfig file like below to enable accumulation by default: $ cat ~/.perfconfig [top] children = true And it can be disabled through command line: $ perf top --no-children Signed-off-by: Namhyung Kim <namhyung@kernel.org> Tested-by: Arun Sharma <asharma@fb.com> Tested-by: Rodrigo Campos <rodrigo@sdfg.com.ar> Cc: Frederic Weisbecker <fweisbec@gmail.com> Link: http://lkml.kernel.org/r/1401335910-16832-22-git-send-email-namhyung@kernel.org Signed-off-by: Jiri Olsa <jolsa@kernel.org>
