  1. What are out critical outcomes ?
  2. What are the most critical areas to document ?
  3. Discussion on Architecture and Requirements
  4. Timelines / Milestones ?
  5. What needs to be ported, who and when ?



Notes during the meeting:


  • Topics to discuss:
    • Architecture discussion
      • specialized HW
      • special controls
      • Sound from remote devices
        • tcp/ip
        • can connect


Architecture Diagram to start with:



  session manager able to configure dsp?


   open/ proprietary networkmanager separate!


  external (zephyr/autosar) devices reserve/create ressource




  Gateway/Portal handling ressource/ACL management. Returning ressource URI  (socket or network endpoint)


 

1) client connects using (no / invalid) token

2) service reacts with refusal and ID/Link to authority

3) client connects to authority

4) authority grants token

5) client connects to service w/ new token

6) service checks token with authority

7) authority verifies token

8) access granted


→ similar / equal to oauth/openID mechanism


Summary #1:

  • In a car we have (proprietary) network managers. The pipewire session manager needs to communicate with these and provide an API.
    • Similar for copy protection mechanisms.
    • Thus session manager cannot (shouldn't try) to abstract all of these.
    • System management might be on external hardware
  • Security provided by a gateway/portal that handles ressource managment and authoriztion.
    • Need to take HDCP/content protection in mind (e.g. videvine)


TODO: Session Manager first.


Issues:

  • static and/or default config   vs dynamic configuration  at runtime
  • handle device removal
  • graph inplemented in HW level
