Subject: [dpdk-stable] [PATCH 00/15] Introduce Virtio vDPA driver
Date: Thu, 29 Aug 2019 09:59:45 +0200
Message-ID: <20190829080000.20806-1-maxime.coquelin@redhat.com> (raw)

vDPA allows to offload Virtio Datapath processing by supported
NICs, like IFCVF for example.

The control path has to be handled by a dedicated vDPA driver,
so that it can translate Vhost-user protocol requests to
proprietary NICs registers accesses.

This driver is the vDPA driver for Virtio devices, meaning
that Vhost-user protocol requests get translated to Virtio
registers accesses as per defined in the Virtio spec.

Basically, it can be used within a guest with a para-virtualized
Virtio-net device, or even with a full Virtio HW offload NIC
directly on host.

Amongst the main features, all currently supported Virtio spec
versions are supported (split & packed rings, but only tested
with split ring for now) and also multiqueue support is added
by implementing the cotnrol virtqueue in the driver.

The structure of this driver is heavily based on IFCVF vDPA.

Maxime Coquelin (15):
  vhost: remove vhost kernel header inclusion
  vhost: configure vDPA as soon as the device is ready
  net/virtio: move control path fonctions in virtqueue file
  net/virtio: add virtio PCI subsystem device ID declaration
  net/virtio: save notify bar ID in virtio HW struct
  net/virtio: add skeleton for virtio vDPA driver
  net/virtio: add vDPA ops to get number of queue
  net/virtio: add virtio vDPA op to get features
  net/virtio: add virtio vDPA op to get protocol features
  net/virtio: add vDPA op to configure and start the device
  net/virtio: add vDPA op to stop and close the device
  net/virtio: add vDPA op to set features
  net/virtio: add vDPA ops to get VFIO FDs
  net/virtio: add vDPA op to get notification area
  doc: add documentation for Virtio vDPA driver
