I acked the remaining patch.
Alex, will you take it?

If that's what you prefer, yes.  Thanks,

Alex

[Qemu-devel] [PATCH 0/4] vfio-pci: pass the aer error to guest, part1

[Cao jin]

From: Chen Fan 

this patchset are splited out from my aer series patches,
this part of aer patches is harmless, and have been reviewed-by.
In order to avoid blocking it to merge, so I send it out independently
as part1. the part2 is under discussion. Thanks

Chen Fan (4):
  pcie: modify the capability size assert
  vfio: make the 4 bytes aligned for capability size
  aer: impove pcie_aer_init to support vfio device
  pcie_aer: expose pcie_aer_msg() interface

[Qemu-devel] [PATCH 0/4] VFIO

[Alex Williamson]

This series implements the core VFIO infrastructure, documentation,
an IOMMU backend suitable for x86 usage, and a PCI device driver.
These patches are based on the previous v2 IOMMU Groups + VFIO
patches and are dependent on the previously sent out PCI and IOMMU
groups series found here:

http://marc.info/?l=linux-kernelm=133835363021384
http://marc.info/?l=linux-kernelm=133835480021716

As noted in previous postings and the included documentation, VFIO
provides secure, IOMMU protected, userspace access to I/O devices
for use by things like PCI device assignment to virtual machines
in Qemu.  This driver is meant to replace existing KVM device
assignment and hopefully take over much of what UIO does today.

I'm looking for suggestions not only on the code, but on the best
way to get this upstream.  If we can get some initial blessing for
this driver I'd be happy to host a next branch for it or submit it
as a staging driver.  I think Bjorn and Joerg would probably
appreciate and kind of nod that this driver has legs in order to
include the PCI and IOMMU backend support.  Alexey Kardashevskiy
has already posted an initial draft of POWER support for VFIO
giving some validation as a cross architecture solution.

These patches, as well as the PCI support patches and IOMMU group
infrastructure can be found in git here:

git://github.com/awilliam/linux-vfio.git (iommu-group-vfio-next-20120529)

A qemu tree including a vfio-pci driver capable of assigning PCI
devices to Qemu guests can be found here:

git://github.com/awilliam/qemu-vfio.git (iommu-group-vfio)

Thanks, 
Alex
