[Xen-devel] [PATCH v2 00/11] vpci: add support for SR-IOV capability

[Roger Pau Monne <roger.pau@xxxxxxxxxx>]

Hello,

The following series enables the usage of the SR-IOV capability by a PVH
Dom0. This allows Dom0 to enable virtual functions and access them as it
would do on bare metal.

No changes are needed in the Dom0 kernel in order to manage the PCIe
SR-IOV capability.

The first 10 patches are preparatory changes in order to support SR-IOV.
Patch 11 actually adds support for the capability.

The series can also be found at:

git://xenbits.xen.org/people/royger/xen.git sriov.v2

The series has been tested with a Linux PVH Dom0 and an Intel I350 nic.

Thanks, Roger.
