Subject: [PATCH v13 09/14] perf, tools: Group alias perf list by section
Date: Tue, 2 Jun 2015 10:12:09 -0700 [thread overview]
Message-ID: <1433265135-20426-10-git-send-email-sukadev@linux.vnet.ibm.com> (raw)
In-Reply-To: <1433265135-20426-1-git-send-email-sukadev@linux.vnet.ibm.com>
From: Andi Kleen <ak@linux.intel.com>
The first first element in an hardware event name defines the general
area, usually the part of the micro architecture it is refering to.
Group the perf list output by these sections by adding section headers.
