Subject[PATCH v2 0/7] IOMMU: Groups support
Date
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:

Thanks,

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. Thanks,

Alex
