From: Erwan Yvin <erwan.yvin at stericsson.com> This driver depends on Rusty's new host virtio ring implementation, so this patch-set is based on the vringh branch in Rusty's git. with the vringh wrapper patch on top. They do not apply cleanly on top of the remoteproc virtio config patches from Sjur, but it merges fine. CAIF will use this new host virtio ring implementation. Ido,

...nnot be managed through virtio-config. So the virtio drivers must call functions exported from remoteproc for handling the host-side virtio rings. The functions rproc_virtio_get_vringh(), rproc_virtio_del_vringh(), rproc_virtio_kick_vringh() are added to remoteproc_virtio.c. The existing functions rproc_vq_interrupt() and rproc_virtio_find_vqs() are updated to handle the new vhost rings.

This patch-set introduces the CAIF Virtio Link layer. The purpose is to communicate with a remote processor (a modem) over shared memory. Virtio is used as the transport mechanism, and the Remoteproc framework provides configuration and management of the Virtio rings and devices. The modem and Linux host may be on the same SoC, or connected over a shared memory interface such as LLI. Zero-Copy
