Subject: [PATCH 0/7] IOMMU: Groups support
Date: Tue, 29 May 2012 23:10:01 -0600 [thread overview]
Message-ID: <20120530045150.1543.73660.stgit@bling.home> (raw)
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
