> This patch series submits an initial version of the AVP PMD from Wind River
> Systems.  The series includes shared header files, driver implementation,
> and changes to documentation files in support of this new driver.  The AVP
> driver is a shared memory based device.  It is intended to be used as a PMD
> within a virtual machine running on a Wind River virtualization platform.
> See: http://www.windriver.com/products/titanium-cloud/

> It enables optimized packet throughput without requiring any packet
> processing in qemu. This allowed us to provide our customers with a
> significant performance increase for both DPDK and non-DPDK applications
> in the VM.   Since our AVP implementation supports VM live-migration it
> is viewed as a better alternative to PCI passthrough or PCI SRIOV since
> neither of those support VM live-migration without manual intervention
> or significant performance penalties.
>
> Since the initial implementation of AVP devices, vhost-user has become part
> of the qemu offering with a significant performance increase over the
> original virtio implementation.  However, vhost-user still does not achieve
> the level of performance that the AVP device can provide to our customers
> for DPDK based guests.
>
> A number of our customers have requested that we upstream the driver to
> dpdk.org.
