@ -73,3 +73,23 @@ Description:
This sysfs entry tells us whether the channel is a local
server channel that is announced (values are either
true or false).
What: /sys/bus/rpmsg/devices/.../driver_override
Date: April 2018
KernelVersion: 4.18
Contact: Bjorn Andersson <[email protected]>
Description:
Every rpmsg device is a communication channel with a remote
processor. Channels are identified by a textual name (see
/sys/bus/rpmsg/devices/.../name above) and have a local
("source") rpmsg address, and remote ("destination") rpmsg
address.
The listening entity (or client) which communicates with a
remote processor is referred as rpmsg driver. The rpmsg device
and rpmsg driver are matched based on rpmsg device name and
rpmsg driver ID table.
This sysfs entry allows the rpmsg driver for a rpmsg device
to be specified which will override standard OF, ID table
and name matching.
