[PATCH 0/7] IOMMU: Groups support

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

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


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,
