Summary
•
Inter Display protocol is really mandatory for near
feature to collaborate with ECUs.
•
Wayland/Weston community is the best place to
be upstreamed.
–
Define Inter Display protocol
–
Reference implementation to share physical memory
needs to be adapted for each users preferable.
–
At first, Linux <-> Linux environment.
•
To be proposed to SAT
as AGL activity.
•
TODO:
collaboration with Security framework.
This overview delves into the standardization of the Inter-Display Protocol using Wayland/Weston, focusing on sharing surfaces between ECUs and OSs. It explores the definition of the protocol at Wayland, receiver daemon, HMI transmitter plugin, Weston core, backend, adaptation plugins, and implementation of reference protocols like RTP, LVDS, and Ethernet AVB.
