[PATCH 0/5] PCI: Prep for VFIO and IOMMU Groups

From: Alex Williamson
Date: Wed May 30 2012 - 00:50:49 EST


These are the PCI related patches from the previously submitted
v2 IOMMU Groups + VFIO series. I've updated them with Don's
comments and split them off on their own so that we can hopefully
make some progress getting these in. Patches are against 20120529
linux-next tree.

Patches 1 & 2 provide DMA quirking and ACS checking which will be
used by IOMMU drivers supporting IOMMU groups. Patch 3 enables the
set of pci user config access functions to be called from other
modules, which will be used by VFIO-pci. Patch 4 enables a common
translation of pcibios errors into errno for returning to userspace,
also to be used by VFIO-pci. Patch 5 adds additional PCI register
definitions so we can more easily parse config space for devices in
VFIO-pci.

These patches, as well as IOMMU group support 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
