Subject: [dpdk-dev] [PATCH v3 0/2] Vhost-vDPA fixes
Date: Fri,  8 Jan 2021 10:41:47 +0100
Message-ID: <20210108094149.215384-1-maxime.coquelin@redhat.com> (raw)

Vhost-vDPA support in Virtio-user PMD was lacking
backend features negotiation and IOTLB batching
support, causing intialization issues with Mellanox
vDPA device managed by Kernel vDPA framework.

Changes in v3:
- Fix protocol features negotiation condition (Chenbo)
- Fixup comment in struct declaration (Chenbo)

Changes in v2:
- Add backend features negotiation (David, Jason)
- Ensure Kernel supports IOTLB MSG v2

Maxime Coquelin (2):
  net/virtio: fix missing backend features negotiation
  net/virtio: fix memory init with vDPA backend
