Subject: [PATCH 15/21] perf report: Add report.children config option
Date: Tue, 24 Dec 2013 17:22:21 +0900	[thread overview]
Message-ID: <1387873347-28838-16-git-send-email-namhyung@kernel.org> (raw)
In-Reply-To: <1387873347-28838-1-git-send-email-namhyung@kernel.org>

From: Namhyung Kim <namhyung.kim@lge.com>

Add report.children config option for setting default value of
callchain accumulation.  It affects the report output only if
perf.data contains callchain info.

A user can write .perfconfig file like below to enable accumulation
by default:

  $ cat ~/.perfconfig
  [report]
  children = true

And it can be disabled through command line:

  $ perf report --no-children
