Usually folks use rpmsg for those things. rpmsg is using shared memory as transport mechanism and virtio is providing this. rpmsg is conceptually a child of virtio: when the subsystem was proposed by TI Arnd noted that virtio has large similarities in shared memory transport and as the potential reuse for buffer handling etc was excellent virtio was used as a base for rpmsg/remoteproc work.
