[v4,0/6] Vhost-vdpa Shadow Virtqueue multiqueue support.

Message

Eugenio Perez Martin Sept. 6, 2022, 3:07 p.m. UTC

This series enables shadowed CVQ to intercept multiqueue commands through
shadowed CVQ, update the virtio NIC device model so qemu send it in a
migration, and the restore of that MQ state in the destination.

v3:
* Accept ctrl class and cmd in vhost_vdpa_net_load_cmd, so it's in charge of
  building the whole buffer
* Rename cvq_cmd_in_buffer to status.

v2:
* Add vhost_vdpa_net_load_cmd helper to avoid out buffers castings.
* Make cvq_cmd_in_buffer virtio_net_ctrl_ack type.

Eugenio Pérez (6):
  vdpa: Make VhostVDPAState cvq_cmd_in_buffer control ack type
  vdpa: extract vhost_vdpa_net_load_mac from vhost_vdpa_net_load
  vdpa: Add vhost_vdpa_net_load_mq
  vdpa: validate MQ CVQ commands
  virtio-net: Update virtio-net curr_queue_pairs in vdpa backends
  vdpa: Allow MQ feature in SVQ
