You sent v12, so not this one for sure.
v12 triggered kbuild warnings, you need to fix them and repost.
Note that I'm on vacation from monday, so if you want this

How about implementing the wrappers along with virtqueue_dma_dev() to
see if Christoph is happy?

Commit 25266128fe16 ("virtio-net: fix race between set queues and
probe") tries to fix the race between set queues and probe by calling
_virtnet_set_queues() before DRIVER_OK is set. This violates virtio
spec. Fixing this by setting queues after virtio_device_ready().

Could we push this to the next linux version?

Userspace knows if the device has dedicated descriptor group or not
by checking this feature bit.
It's only exposed if the vdpa driver backend implements the
.get_vq_desc_group() operation callback. Userspace trying to negotiate
this feature when it or the dependent _F_IOTLB_ASID feature hasn't

Following patchset introduces dedicated group for descriptor table to
reduce live migration downtime when passthrough VQ is being switched
to shadow VQ. As this RFC set is to seek early feedback on the uAPI
and driver API part, for now there's no associated driver patch consuming
the API. As soon a
In some cases, the access to the virtqueue's descriptor table (including
the associated available and used ring for split layout) has to be
isolated from guest memory access where the buffer address contained in
vring descriptor points to. Introduce dedicated descriptor group with
driver op .get_vq
With _F_DESC_ASID backend feature, the device can now support the
VHOST_VDPA_GET_VRING_DESC_GROUP ioctl, and it may expose the descriptor
table (including avail and used ring) in a different group than the
buffers it contains. This new uAPI will fetch the group ID of the
descriptor table.
