From patchwork Thu Jun 24 04:41:05 2010 Content-Type: text/plain; charset="utf-8" MIME-Version: 1.0 Content-Transfer-Encoding: 7bit Subject: [02/15] qdev: Add a get_dev_path() function to BusInfo Date: Wed, 23 Jun 2010 18:41:05 -0000 From: Alex Williamson X-Patchwork-Id: 56743 Message-Id: <20100624044105.16168.95440.stgit@localhost.localdomain> To: qemu-devel@nongnu.org Cc: jan.kiszka@siemens.com, armbru@redhat.com, alex.williamson@redhat.com, kraxel@redhat.com, cam@cs.ualberta.ca, paul@codesourcery.com This function is meant to provide a stable device path for buses which are able to implement it. If a bus has a globally unique addresses scheme, one address level may be sufficient to provide a path. Other buses may need to recursively traverse up the qdev tree.
