Subject: [dpdk-dev] [PATCH 08/40] net/virtio: force IOVA as VA mode for Virtio-user
Date: Sun, 20 Dec 2020 22:13:33 +0100
Message-ID: <20201220211405.313012-9-maxime.coquelin@redhat.com> (raw)
In-Reply-To: <20201220211405.313012-1-maxime.coquelin@redhat.com>

At least Vhost-user backend of Virtio-user PMD requires
IOVA as VA mode. Until now, it was implemented as a hack
by forcing to use mbuf's buf_addr field instead of buf_iova.

This patcv removes all this logic and just fails probing
if IOVA as VA mode is not selected. It simplifies the
code overall, and removes some bus-specific logic from
generic virtio_ethdev.c.
