From 5cfe2c82f3eb6876cf4b55e99decea0bd015d6b8 Mon Sep 17 00:00:00 2001 From: Jiri Olsa Date: Mon, 9 Dec 2013 11:02:49 +0100 Subject: perf report: Add --header/--header-only options Currently the perf.data header is always displayed for stdio output, which is no always useful. Disabling header information by default and adding following options to control header output: --header - display header information (old default) --header-only - display header information only w/o further processing, forces stdio output Signed-off-by: Jiri Olsa Acked-by: David Ahern Cc: Corey Ashford Cc: David Ahern Cc: Frederic Weisbecker Cc: Ingo Molnar Cc: Namhyung Kim Cc: Paul Mackerras Cc: Peter Zijlstra Cc: Stephane Eranian Link: http://lkml.kernel.org/r/1386583370-1699-2-git-send-email-jolsa@redhat.com [ Added single line explaining talking about the new --header* options, to address David Ahern comment; better man page entry for the new options, from Namhyung Kim ] Signed-off-by: Arnaldo Carvalho de Melo --- tools/perf/Documentation/perf-report.txt | 9 +++++++++ 1 file changed, 9 insertions(+) (limited to 'tools/perf/Documentation') diff --git a/tools/perf/Documentation/perf-report.txt b/tools/perf/Documentation/perf-report.txt index 10a279871251..8eab8a4bdeb8 100644 --- a/tools/perf/Documentation/perf-report.txt +++ b/tools/perf/Documentation/perf-report.txt @@ -237,6 +237,15 @@ OPTIONS Do not show entries which have an overhead under that percent.
