Raw Blame History

From 48b28b6aec23b82c0239aee60af2a470c06dde1a Mon Sep 17 00:00:00 2001
From: Xu Wang <gesaint@linux.vnet.ibm.com>
Date: Mon, 17 Mar 2014 19:21:23 -0400
Subject: [PATCH 51/60] Parse/Store controller XML tags
Parse and store the <controller> XML tags. The generated DeviceID will
be a combination of "controller" + XML device "name" + XML Index "value".
This should be unique enough now and generates "controller:pci:0" or
"controller:usb:0" DeviceID's.
In the future, if support is added for the "<master>" XML child a new
mechanism will need to be put in place since one of those controllers is
designed to have the same name and index - what changes is the function
for the device.
