2017-07-14rpmsg.txt: standardize document formatMauro Carvalho Chehab1-144/+204
Each text file under Documentation follows a different format. Some doesn't even have titles! Change its representation to follow the adopted standard, using ReST markups for it to be parseable by Sphinx: - mark document and chapter titles; - mark notes; - mark literal blocks; - adjust identation.

2016-05-06rpmsg: drop owner assignment from rpmsg_driversAndrew F. Davis1-1/+0
An rpmsg_driver does not need to set an owner, it will be populated by the driver core. Signed-off-by: Andrew F. Davis <afd@ti.com> Signed-off-by: Bjorn Andersson <bjorn.andersson@linaro.org>
2013-01-04Documentation: remove __dev* attributes.Greg Kroah-Hartman1-2/+2
CONFIG_HOTPLUG is going away as an option. As a result, the __dev* markings need to be removed. This change removes the use of __devinit, __devexit_p, __devinitdata, __devinitconst, and __devexit from the kernel documentation. Based on patches originally written by Bill Pemberton, but redone by me in order to handle some of the coding style issues better, by hand.

2012-02-09rpmsg: add virtio-based remote processor messaging busOhad Ben-Cohen1-0/+293
Add a virtio-based inter-processor communication bus, which enables kernel drivers to communicate with entities, running on remote processors, over shared memory using a simple messaging protocol. Every pair of AMP processors share two vrings, which are used to send and receive the messages over shared memory. The header of every message sent on the rpmsg bus contains src and dst addresses, which make it possible to multiplex several rpmsg channels on the same vring. Every rpmsg channel is a device on this bus. When a channel is added, and an appropriate rpmsg driver is found and probed, it is also assigned a local rpmsg address, which is then bound to the driver's callback. When inbound messages carry the local address of a bound driver, its callback is invoked by the bus. This patch provides a kernel interface only; user space interfaces will be later exposed by kernel users of this rpmsg bus. Designed with Brian Swetland <swetland@google.com>.
