[v2,0/6] Vhost-vdpa Shadow Virtqueue multiqueue support.

Message

Eugenio Perez Martin Aug. 24, 2022, 6:35 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.

It needs to be applied on top of [1].

[1] https://lists.gnu.org/archive/html/qemu-devel/2022-08/msg02965.html

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_out_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 feture in SVQ

(Typo here).

Looks good, let's wait for confirmation from Si Wei. Then I can queue
this series.

Thanks
