VFIO kernel support was just merged into Linux, so I'd like to formally propose inclusion of the QEMU vfio-pci driver for QEMU 1.2. Included here is support for x86 PCI device assignment. PCI INTx is not yet enabled, but devices making use of either MSI or MSI-X work. The level irqfd and eoifd support I've proposed for KVM enable an accelerated patch for this through KVM. I'd like to get this base driver in first and enable the remaining support in-tree. I've split this version up a little from the RFC to make it a bit easier to review. Review comments from Blue Swirl and Avi are already incorporated, including Avi's requests to simplify both the PCI BAR mapping and unmapping paths.
