Subject: [PATCH 2/5] perf, tools: Add one liner warning for disabled features
Date: Wed, 18 Jan 2017 17:41:47 -0800	[thread overview]
Message-ID: <20170119014150.19218-3-andi@firstfloor.org> (raw)
In-Reply-To: <20170119014150.19218-1-andi@firstfloor.org>

From: Andi Kleen <ak@linux.intel.com>

Add a one liner warning for perf features that need to be enabled
explicitly by the user, so that they know they are missing something.
Currently enabled for XED and BABELTRACE.
