Today this prevents vhost-us= er-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 contrib/libvhost-user/libvhost-user-glib.h | 2 +- contrib/libvhost-user/libvhost-user.h | 10 +++- contrib/libvhost-user/libvhost-user-glib.c | 12 +++- contrib/libvhost-user/libvhost-user.c | 66 ++++++++++++++-------- contrib/vhost-user-blk/vhost-user-blk.c | 16 +++--- contrib/vhost-user-gpu/main.c | 9 ++- contrib/vhost-user-input/main.c | 11 +++- contrib/vhost-user-scsi/vhost-user-scsi.c | 21 +++---- tests/vhost-user-bridge.c | 42 +++++++++----- docs/interop/vhost-user.rst | 21 +++---- 10 files changed, 133 insertions(+), 77 deletions(-) --=20 2.21.0
