v3:
- Incorporate feedback from Anthony, Avi, and Jan (Thank you!)
I've also added a new tag to my github tree, so those who have
already reviewed can check the delta by comparing:
git://github.com/awilliam/qemu-vfio.git
tags/vfio-pci-for-qemu-1.2
tags/vfio-pci-for-qemu-1.2-v2
tags/vfio-pci-for-qemu-1.2-v3
Blue Swirl already offered an Ack-by for previous version, I'll
hope, but won't assume that carries forward. Original description
below with updated tag. Thanks,
Alex
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.
This series is also available at:

Thanks,
Alex
