v2: - Trickle down changes from pci_get_dma_source() to better handle PCI device reference counting in IOMMU driver patches
This depends on v2 PCI patches: http://marc.info/?l=linux-kernel&m=133840870510712 Thanks, Alex v1: These are the IOMMU related patches from the v2 IOMMU Groups + VFIO series. I've separated out PCI and VFIO to try to make progress on the foundation we need for VFIO. Patches 5 & 6 of this series depend on patches 1 & 2 of the PCI series found here: http://marc.info/?l=linux-kernel&m=133835363021384 Patch 1 adds an iommu_group pointer to struct device so that we have a place to link a device to a specific iommu group. GregKH has already acked this, so it should go in with the group support itself. Patch 2 is the core of the IOMMU group support. Patches 3 & 4 allow groups to be created on AMD-Vi and Intel VT-d systems. Patches 5 & 6 make use of the additional PCI DMA quirks and ACS support checking to make groups more secure. Patch 7 removes the iommu=group_mf option as ACS checking results in most multifunction devices being grouped already. These patches, as well as the PCI support patches and VFIO can be found in git here: git://github.com/awilliam/linux-vfio.git (iommu-group-vfio-next-20120529) Please consider these for 3.5, but I'll settle for any kind of next branch.
