Version 2 incorporating acks and feedback from v1. The PCI DMA quirk and ACS check are reworked, sysfs iommu groups ABI Documentation added as well as numerous other fixes, including patches from Alexey Kardashevskiy towards supporting POWER usage of VFIO and IOMMU groups. This series can be found here on top of 3.4: git://github.com/awilliam/linux-vfio.git iommu-group-vfio-20120521 The Qemu tree has also been updated to Qemu 1.1 and can be found here: git://github.com/awilliam/qemu-vfio.git iommu-group-vfio I'd really like to make a push to get this in for 3.5, so let's talk about how to do that across iommu, pci, and new driver. Joerg, are you sufficiently happy with the IOMMU group concept and code? We'll also need David Woodhouse buyin on the intel-iommu changes in patches 3 & 6. Who needs to approve VFIO as a new driver, GregKH? Bjorn, I'd be happy to send the PCI changes as a series for you, but I wonder if it makes sense to collect acks for them if you approve and bundle them in with the associated code that needs them so you're not left with unused code. Let me know which you prefer. If there are better ways to do it, please let me know.
