This introduces vringh, which are generic accessors for virtio rings (host side). There's a host-side implementation in vhost, but it assumes that the rings are in userspace, and is tied to the vhost implementation. I have patches to adapt it to use vringh, but I'm pushing this in the next merge window for Sjur, who has CAIF patches which need it. This also includes a test program in

PCIe endpoint framework provides APIs to implement PCIe endpoint function. This framework allows defining various PCIe endpoint function behaviors in software. This patch extend the framework for virtio pci device. The virtio is defined to communicate guest on virtual machine and host side. Advantage of the virtio is the efficiency of data transfer and the conciseness of implementation device

...s on Rusty's new host virtio ring implementation, so this patch-set is based on the vringh branch in Rusty's git. Changes since V1: - Use the new iov helper functions, and simplify iov handling. However this triggers compile warnings, as it takes struct iov while kernel api uses struct kiov - Introduced the module_virtio_driver macro - Pass NULL as wiov to vringh_getdesc_kern() Regards, Sjur Sjur Br?ndeland (2): remoteproc: Add support for vringh (Host vrings) virtio: Add module driver macro for virtio drivers.

From: Sjur Br?ndeland <sjur.brandeland at stericsson.com> This patch-set introduces the CAIF Virtio Link layer driver. 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.
