Linus Torvalds 46b407ca4a remoteproc/rpmsg: new subsystem ... This new subsystem provides a common way to talk to secondary processors on an SoC, e.g. a DSP, GPU or service processor, using virtio as the transport. In the long run, it should replace a few dozen vendor specific ways to do the same thing, which all never made it into the upstream kernel. There is a broad agreement that rpmsg is the way to go here and several vendors have started working on replacing their own subsystems. Two branches each add one virtio protocol number. Fortunately the numbers were agreed upon in advance, so there are only context changes.
