Subject: [PATCH 10/19] perf, c2c: Rework setup code to prepare for features
Date: Fri, 28 Feb 2014 12:42:59 -0500 [thread overview]
Message-ID: <1393609388-40489-11-git-send-email-dzickus@redhat.com> (raw)
In-Reply-To: <1393609388-40489-1-git-send-email-dzickus@redhat.com>
A basic patch that re-arranges some of the c2c code and adds a couple
of small features to lay the ground work for the rest of the patch
series.
Changes include:
o reworking the report path
o replace preprocess_sample with simpler calls
o rework raw output to handle separators
o remove phys id gunk
o add some generic options
There isn't much meat in this patch just a bunch of code movement and cleanups.
V2: refresh to latest upstream changes
