Subject: [dpdk-dev] [PATCH v3 0/8] virtio-user: introduce vhost-vdpa backend
Date: Tue, 29 Sep 2020 18:13:56 +0200
Message-ID: <20200929161404.124580-1-maxime.coquelin@redhat.com> (raw)

vhost-vDPA is a new vhost backend type introduced by vDPA kernel
framework, which provides abstruction to the vDPA devices and
exposes to userspace a unified control interface through char devs.

This patch set adds vhost-vdpa backend type to the virtio_user.
A set of vhost-vdpa specific ops callbacks are attached to the
virtio_user according to the runtime dynamic check result of the
backend type. DMA memory map/unmap callbacks are added to both
vdev bus driver and virtio_user pmd to support address mapping.
In addition, minor fixes to existing virtio control path are also
implemented to make the new backend work.

This is a collaborative work done with Patrick Fu from Intel and
Adrian Moreno from Red Hat. Thanks to them for their contributions.

The series has been tested with vdpasim and Intel IFC Kernel vDPA
drivers, and more lightly with Mellanox mlx5_vdpa on ConnectX-6 Dx.

Changes in v3:
--------------
 * Fix 32bit builds (CI & Chenbo)
 * Fix checkpatch

Changes in v2:
--------------
 * Split backend-type patch (Adrian)
 * Fix get_status size (Chenbo)
 * Various minro fixes (Chenbo)
