This series enables shadowed CVQ to intercept Offloads commands through shadowed CVQ, update the virtio NIC device model so qemu send it in a migration, and the restore of that Offloads state in the destination. Changelog ========= v4: - refactor the commit message suggested by Eugenio in patch#4 "virtio-net: expose virtio_net_supported_guest_offloads()" - fix the wrong "cpu_to_le64()" pointed out by Eugenio in patch$5 "vdpa: Add vhost_vdpa_net_load_offloads()" - refactor the comment in patch#5 "vdpa: Add vhost_vdpa_net_load_offloads()" v3: https://lists.nongnu.org/archive/html/qemu-devel/2023-06/msg00206.html v2: https://lists.nongnu.org/archive/html/qemu-devel/2023-06/msg00044.html v1: https://lists.nongnu.org/archive/html/qemu-devel/2023-05/msg07198.html Hawkins Jiawei (6): include/hw/virtio: make some VirtIODevice const vdpa: reuse virtio_vdev_has_feature() hw/net/virtio-net: make some VirtIONet const virtio-net: expose virtio_net_supported_guest_offloads() vdpa: Add vhost_vdpa_net_load_offloads() vdpa: Allow VIRTIO_NET_F_CTRL_GUEST_OFFLOADS in SVQ hw/net/virtio-net.c | 2 +- include/hw/virtio/virtio-net.h | 1 + include/hw/virtio/virtio.h | 2 +- net/vhost-vdpa.c | 49 +++++++++++++++++++++++++++++++--- 4 files changed, 48 insertions(+), 6 deletions(-) -- 2.25.1
QE tested this series v4 on the vp_vdpa device with the following scenarios: reboot/shutdown, hotplug/unplug, nic driver load/unload, ping, vDPA control virtqueue(changed the mac address), everything are working fine. And L1 guest will not appear error messages "vdpa svq does not work with features 0x4" after applied this series of patches.

A reviewer may see this newly from an older revision. Apart from that, Reviewed-by: Eugenio Pérez <eperezma@redhat.com> Tested-by: Eugenio Pérez <eperezma@redhat.com> I tested it by tracing the value it sends at destination when the guest enable or disable hw GRO offloads with: ethtool -K rx-gro-hw off. As you point in previous series, a migration blocker needs to be conditionally added. This is done in [1]. While investigating this I discovered two related issues, it might be in handy if other reviewer wants to test the changes [2][3]. Thanks!
