UI and Graphic EG
AGL would evolve as a Cockpit system more?
- To be collaborated with other Operation systems.
- To support more application.

• Standard protocol Collaboration with OSs
• Virtualization support
Standard protocol Collaboration with Various Operation systems.

An OS (RTOS,
Linux,,,)
• An Operation system will be replaced by each OEM/Tiers for product
• OS will be various
• RTOS, Linux,,,,
• The way of physical will be various as well
• MOST, Ethernet, LVDS, Virtualization shmem,,,,,,
Goal: AGL distribution support standard protocol to be connected to
Other OSs easily.
Solution:
• Graphics:
• Make the logical protocol as standard in Wayland
(*) Waylanｄ is now default of Fedora. Good place to
contribute.
• Contribute Plugin to hide physical to be fit to a loadable module
on Weston, Mutter,,,,,,
CES 2017 Cluster Demo 1/2
• Share navi map between IVI and Cluster
• IVI side navi map is shared to the center of the cluster side
CES 2017 Cluster Demo 2/2

Contact me when you are interested
in joining
Listing up applications in AGL wiki
page to be announced for AGL
members.
Benefit:
- OEM/Tier easily try out application
- Application vendor to be
advertised as AGL compatible.

• Red highlighted words components are the target of development in 2017
• Have an ivestigation and discussion are needed for compositor and shell
• As 2017 activity, we should discuss and choose one
Other
OS/ECU
Waltham usecase
• 1. Display map and MM info in center display on cluster
• Navigation should create map and MM info only for cluster
• The size and other display information of cluster are sent from cluster-side ECU/OS by waltham
protocol
• Center display gets the above info and transfers surface
Center display

Waltham overview
• ivi-controller load transmitter.so
• Transmitter.so is a plugin which handle transfer surface and connection between both ECU/OS
• Reciever application directly connect to transmitter side
