From 1b6370463e88b0c1c317de16d7b962acc1dab4f2 Mon Sep 17 00:00:00 2001 From: Sjur Brændeland Date: Fri, 14 Dec 2012 14:40:51 +1030 Subject: virtio_console: Add support for remoteproc serial MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Add a simple serial connection driver called VIRTIO_ID_RPROC_SERIAL (11) for communicating with a remote processor in an asymmetric multi-processing configuration. This implementation reuses the existing virtio_console implementation, and adds support for DMA allocation of data buffers and disables use of tty console and the virtio control queue.
