Subject: [PATCH v2 0/3] vduse: add support for networking devices
Date: Tue, 4 Jul 2023 18:40:42 +0200 [thread overview]
Message-ID: <20230704164045.39119-1-maxime.coquelin@redhat.com> (raw)
This small series enables virtio-net device type in VDUSE.
With it, basic operation have been tested, both with
virtio-vdpa and vhost-vdpa using DPDK Vhost library series
adding VDUSE support using split rings layout (merged in
DPDK v23.07-rc1).
Control queue support (and so multiqueue) has also been
tested, but requires a Kernel series from Jason Wang
relaxing control queue polling [1] to function reliably,
so while Jason rework is done, a patch is added to disable
CVQ and features that depend on it (tested also with DPDK
v23.07-rc1).

=================
- Add a patch to disable CVQ (Michael)
RFC -> v1 changes:
==================
- Fail device init if it does not support VERSION_1 (Jason)
Maxime Coquelin (3):
vduse: validate block features only with block devices
