2018-12-14Simpler handling of binding subscriptionsRomain Forlot1-46/+39
Don't use a child class for subscription, only use one because there isn't other different subscriptions type to be implemented about now and if so then we could split again. Remove functions no longer useful and move afb events and afb subscriptions part to low-can-subscription Change-Id: Ie3e4255961ac557465098cdb48730098a950461a Signed-off-by: Romain Forlot <romain.forlot@iot.bzh>

2018-12-14CAN FD implementationRomain Forlot1-33/+30
Add a flag to CAN message definitions which set the message as using FD protocol if true. Use a new generated file with the new FD flag field on the message definitions. Change BCM socket "struct" using an union to store the CAN frames either using the FD struct or the classic non FD struct. A BCM socket can only one frame type once configured. Use as much as possible the "struct canfd_frame" in the binding and only make a difference before writing or reading the socket. From a memory point of view both struct are identical and only the last member differ and could hold more data with messages of 64 bytes long. So the canfd_frame is compatible with the can_frame and can be differentiated by a flag set in the can_id member. Remove now unused code processing can_frame. Keep the diagnostic manager using the classic CAN frame. Set the maximum number of frames that a BCM socket can handle to 257.

2018-04-17Detect engine state and use it during diagnostic messages subscriptionsJonathan Aillet1-3/+28
Get engine state recurringly by requesting a permanent diagnostic messages request. Use these information to warn that diagnostic request won't have any responses at the moment of subscription if engine is off.

2018-04-17Add possibility to subscribe to a recurring request permanentlyJonathan Aillet1-8/+17
Add possibility to subscribe to a recurring request that won't be deleted when no subscriber is detected. For now, this functionnality is implemented for internal use only.

2018-03-15Change subscribed signals search to check filters as wellJonathan Aillet1-3/+2
When a new subscription is made, search in existing subscription for a combination of a signal and a filter instead of searching for just a signal. In this way, each subscription will receive signals according to their requesting filter.
