That sounds cool, I like the idea of exposing this using virtio.

I've looked at that restriction a few times and I believe this is an
artificial limit, but I do not have the history behind it.

I have not seen any such patches, nor heard of people trying to use
remoteproc like you suggest; but I like it!


Please do write up a patch making the vring array of rproc_vdev
dynamically sized (1) and drop the restriction check and we will review
that.

(1) Preferably using a zero-length array at the end of the rproc_vdev
struct.
