Subject: [PATCH V2 14/21] vhost-vdpa: prepare for the multiqueue support
Date: Fri, 3 Sep 2021 17:10:24 +0800 [thread overview]
Message-ID: <20210903091031.47303-15-jasowang@redhat.com> (raw)
In-Reply-To: <20210903091031.47303-1-jasowang@redhat.com>
Unlike vhost-kernel, vhost-vdpa adapts a single device multiqueue
model. So we need to simply use virtqueue index as the vhost virtqueue
index. This is a must for multiqueue to work for vhost-vdpa.
