samples/rpmsg: Introduce a module parameter for message count

2019-08-27T05:10:39+00:00

The current rpmsg_client_sample uses a fixed number of messages to be sent to each instance. This is currently set at 100. Introduce an optional module parameter 'count' so that the number of messages to be exchanged can be made flexible. Signed-off-by: Suman Anna Signed-off-by: Bjorn Andersson

samples/rpmsg: Replace print_hex_dump() with print_hex_dump_debug()

2019-08-27T05:10:28+00:00

Replace the raw print_hex_dump() call in the rpmsg_sample_cb() function with the equivalent print_hex_dump_debug() better suited for dynamic debug. This switch allows flexibility of controlling this trace through dynamic debug when enabled. Signed-off-by: Suman Anna Signed-off-by: Bjorn Andersson

rpmsg: Allow callback to return errors

2016-09-09T05:15:25+00:00

Some rpmsg backends support holding on to and redelivering messages upon failed handling of them, so provide a way for the callback to report and error and allow the backends to handle this. Signed-off-by: Bjorn Andersson

rpmsg: Clean up rpmsg device vs channel naming

2016-09-09T05:15:20+00:00

The rpmsg device representing struct is called rpmsg_channel and the variable name used throughout is rpdev, with the communication happening on endpoints it's clearer to just call this a "device" in a public API. Signed-off-by: Bjorn Andersson

rpmsg: rpmsg_send() operations takes rpmsg_endpoint

2016-09-09T05:15:19+00:00

The rpmsg_send() operations has been taking a rpmsg_device, but this forces users of secondary rpmsg_endpoints to use the rpmsg_sendto() interface - by extracting source and destination from the given data structures. If we instead pass the rpmsg_endpoint to these functions a service can use rpmsg_sendto() to respond to messages, even on secondary endpoints. In addition this would allow us to support operations on multiple channels in future backends that does not support off-channel operations. Signed-off-by: Bjorn Andersson

samples/rpmsg: add support for multiple instances

2016-08-13T04:26:21+00:00

The current rpmsg_client_sample is a very simple example and is not designed to handle multiple instances. Add support for multiple instances, so that the same number of pings are sent to each instance. The instances can be on one or multiple remote processors.

rpmsg: use module_rpmsg_driver in existing drivers and examples

Existing drivers and examples are updated to use the module_rpmsg_driver helper macro. Signed-off-by: Andrew F. Davis Signed-off-by: Bjorn Andersson

rpmsg: drop owner assignment from rpmsg_drivers
