From 4f43c1ff3b8ce99de80db7c51423e5ba8b143802 Mon Sep 17 00:00:00 2001 From: Alex Williamson Date: Fri, 25 Jun 2010 11:08:59 -0600 Subject: pci: Implement BusInfo.get_dev_path() This works great for PCI since a ::. uniquely describes a global address. No need to traverse up the qdev tree. PCI segment support is a placeholder for compatibility once we support multiple segments.
