Subject: [Qemu-devel] [PATCH v2 0/4] libvhost-user: VHOST_USER_PROTOCOL_F_MQ support
Date: Wed, 26 Jun 2019 08:48:11 +0100 [thread overview]
Message-ID: <20190626074815.19994-1-stefanha@redhat.com> (raw)
v2:
* Add missing dev->max_queues = max_queues assignment in vu_init() [dgilbert]
* Folded in Marc-André's Reviewed-By
Sebastien Boeuf <sebastien.boeuf@intel.com> pointed out that libvhost-user
doesn't advertise VHOST_USER_PROTOCOL_F_MQ. Today this prevents vhost-user-net
multiqueue from working.
In virtio-fs we also want to support multiqueue so I'm sending patches to add
this. It's free to advertise VHOST_USER_PROTOCOL_F_MQ for all devices so we
can do it unconditionally in libvhost-user.
Several related improvements are included:
Patch 1 - clean up duplicated and risky VhostUserMsg reply building code
Patch 2 - remove hardcoded 8 virtqueue limit in libvhost-user
Patch 4 - clarify vhost-user multiqueue specification
Stefan Hajnoczi (4):
libvhost-user: add vmsg_set_reply_u64() helper
libvhost-user: support many virtqueues
libvhost-user: implement VHOST_USER_PROTOCOL_F_MQ
docs: avoid vhost-user-net specifics in multiqueue section
