From 535aeaae7de821ba5d43ee2a204ee667ca95aae4 Mon Sep 17 00:00:00 2001 From: Jiri Olsa Date: Mon, 25 Aug 2014 16:45:42 +0200 Subject: [PATCH] perf script: Add period data column Adding period data column to be displayed in perf script. It's possible to get period values using -f option, like: $ perf script -f comm,tid,time,period,ip,sym,dso :26019 26019 52414.329088: 3707 ffffffff8105443a native_write_msr_safe ([kernel.kallsyms]) :26019 26019 52414.329088: 44 ffffffff8105443a native_write_msr_safe ([kernel.kallsyms]) :26019 26019 52414.329093: 1987 ffffffff8105443a native_write_msr_safe ([kernel.kallsyms]) :26019 26019 52414.329093: 6 ffffffff8105443a native_write_msr_safe ([kernel.kallsyms]) ls 26019 52414.329442: 537558 3407c0639c _dl_map_object_from_fd (/usr/lib64/ld-2.17.so) ls 26019 52414.329442: 2099 3407c0639c _dl_map_object_from_fd (/usr/lib64/ld-2.17.so) ls 26019 52414.330181: 1242100 34080917bb get_next_seq (/usr/lib64/libc-2.17.so) ls 26019 52414.330181: 3774 34080917bb get_next_seq (/usr/lib64/libc-2.17.so) ls 26019 52414.331427: 1083662 ffffffff810c7dc2 update_curr ([kernel.kallsyms]) ls 26019 52414.331427: 360 ffffffff810c7dc2 update_curr ([kernel.kallsyms]) Signed-off-by: Jiri Olsa Acked-by: David Ahern Cc: "Jen-Cheng(Tommy) Huang" Cc: Andi Kleen Cc: Corey Ashford Cc: David Ahern Cc: Frederic Weisbecker Cc: Ingo Molnar Cc: Jen-Cheng(Tommy) Huang Cc: Namhyung Kim Cc: Paul Mackerras Cc: Peter Zijlstra Cc: Stephane Eranian Link: http://lkml.kernel.org/r/1408977943-16594-9-git-send-email-jolsa@kernel.org Signed-off-by: Arnaldo Carvalho de Melo --- tools/perf/Documentation/perf-script.txt | 2 +- tools/perf/builtin-script.c | 12 +++++++++++- 2 files changed, 12 insertions(+), 2 deletions(-) diff --git a/tools/perf/Documentation/perf-script.txt b/tools/perf/Documentation/perf-script.txt index 5a0160d..2149480 100644 --- a/tools/perf/Documentation/perf-script.txt +++ b/tools/perf/Documentation/perf-script.txt @@ -115,7 +115,7 @@ OPTIONS -f:: --fields:: Comma separated list of fields to print.
