Subject: [PATCH 02/11] perf, tools: Only print Using CPUID message once
Date: Tue, 18 Oct 2016 16:07:40 -0700 [thread overview]
Message-ID: <1476832069-364-3-git-send-email-andi@firstfloor.org> (raw)
In-Reply-To: <1476832069-364-1-git-send-email-andi@firstfloor.org>
From: Andi Kleen <ak@linux.intel.com>
With uncore event aliases which are duplicated over multiple PMUs
the "Using CPUID" message with -v could be printed many times.
Only print it once.
