From 48481938b02471d505296d7557ed296eb093d496 Mon Sep 17 00:00:00 2001 From: Masami Hiramatsu Date: Mon, 12 Apr 2010 13:16:53 -0400 Subject: perf probe: Support argument name Set given names to event arguments. The syntax is same as kprobe-tracer, you can add 'NAME=' right before each argument. e.g. ./perf probe vfs_read foo=file then, 'foo' is set to the argument name as below. ./perf probe -l probe:vfs_read (on vfs_read@linux-2.6-tip/fs/read_write.c with foo) Cc: Ingo Molnar Cc: Paul Mackerras Cc: Peter Zijlstra Cc: Mike Galbraith Cc: Frederic Weisbecker LKML-Reference: <20100412171653.3790.74624.stgit@localhost6.localdomain6> Signed-off-by: Masami Hiramatsu Signed-off-by: Arnaldo Carvalho de Melo --- tools/perf/util/probe-event.h | 1 + 1 file changed, 1 insertion(+) (limited to 'tools/perf/util/probe-event.h') diff --git a/tools/perf/util/probe-event.h b/tools/perf/util/probe-event.h index 9d99fc24c4fc..10411f596321 100644 --- a/tools/perf/util/probe-event.h +++ b/tools/perf/util/probe-event.h @@ -55,6 +55,7 @@ struct perf_probe_arg_field { /* Perf probe probing argument */ struct perf_probe_arg { char *name; /* Argument name */ + char *var; /* Variable name */ struct perf_probe_arg_field *field; /* Structure fields */ }; -- cgit v1.2.3
