Hello Mathieu,
[...]
A third option would be a combination of both approaches: instantiate the
device using the same name service from the remote side, as done in
rpmsg-tty. In that case, a get_config message, or a similar mechanism, would
also be needed to retrieve the port information from the remote side.
I'm not overly fond of a get_config message because it is one more thing we
have to define and maintain.
Arnaud: is there a get_config message already defined for rpmsg_tty?
No there isn't.
Regards,
Arnaud
Beleswar: Can you provide a link to a virtio device that would use a get_config
message?
Tanmaya also proposed another alternative based on reserved addresses.
At this point, I suggest letting Mathieu review the discussion and recommend
the most suitable approach.
Thanks,
Arnaud
At the end, whatever solution is implemented, my main concern is that the
Linux driver design should, if possible, avoid adding unnecessary complexity
or limitations on the remote side (for instance in openAMP project).
Yes definitely, I want the same. Feel free to let me know if this does
not suit with the OpenAMP project.
Thanks,
Beleswar
Thanks,
Arnaud
So Linux does not need to send the port idx everytime while sending a
gpio message anymore.
Thanks,
Beleswar
