From eb853e80324fa87faf7ae7e1a763ad643f908f2d Mon Sep 17 00:00:00 2001 From: Jiri Olsa Date: Mon, 3 Feb 2014 12:44:42 +0100 Subject: perf tools: Add call-graph option support into .perfconfig Adding call-graph option support into .perfconfig file, so it's now possible use call-graph option like: [top] call-graph = fp [record] call-graph = dwarf,8192 Above options ONLY setup the unwind method. To enable perf record/top to actually use it the command line option -g/-G must be specified. The --call-graph option overloads .perfconfig setup. Assuming above configuration: $ perf record -g ls - enables dwarf unwind with user stack size dump 8192 bytes $ perf top -G - enables frame pointer unwind $ perf record --call-graph=fp ls - enables frame pointer unwind $ perf top --call-graph=dwarf,4096 ls - enables dwarf unwind with user stack size dump 4096 bytes Signed-off-by: Jiri Olsa Cc: Adrian Hunter Cc: Andi Kleen Cc: Corey Ashford Cc: David Ahern Cc: Ingo Molnar Cc: Namhyung Kim Cc: Paul Mackerras Cc: Peter Zijlstra Link: http://lkml.kernel.org/r/1391427883-13443-2-git-send-email-jolsa@redhat.com Signed-off-by: Arnaldo Carvalho de Melo --- tools/perf/perf.h | 1 + 1 file changed, 1 insertion(+) (limited to 'tools/perf/perf.h') diff --git a/tools/perf/perf.h b/tools/perf/perf.h index e84fa26bc1be..2078f334617c 100644 --- a/tools/perf/perf.h +++ b/tools/perf/perf.h @@ -257,6 +257,7 @@ enum perf_call_graph_mode { struct record_opts { struct target target; int call_graph; + bool call_graph_enabled; bool group; bool inherit_stat; bool no_buffering; -- cgit v1.2.3
