[Qemu-devel] [PATCH 0/1] pci: allow 0 address for PCI IO/MEM regions

2014-12-23 Thread Michael Roth
This patch enables the programming of address 0 for IO/MMIO BARs for PCI devices. It was originally included as part of a series implementing PCI hotplug for pseries guests, where it is needed due to the fact that pseries guests access IO space via MMIO, and that IO space is dedicated to PCI devic
