Key Discussion Points
Introductions and Updates:
New attendees introduced themselves, including Mujdat Soyturk from Marmara University, who shared insights about his research lab's focus on connected cars, V2X communication, and software-defined vehicles.
Unified HMI and GRPC Integration:
Unified HMI Capabilities:
Static application layers across multiple displays.
Mirroring applications on multiple displays.
Current support for Wayland Ivi-shell; GRPC integration is in progress.
Demo Scenarios:
Two proposed demo scenarios:
Switching between multiple layout patterns using buttons.
Dynamically launching applications on selected displays.
GRPC integration is critical for advanced demos.
Development Needs:
GRPC integration for AGL compositor is a priority.
Additional application development and interface work required for demos.
GRPC and Wayland Ivi-Shell Discussion:
Marius Vlad raised questions about whether to fully migrate to GRPC or maintain compatibility with Wayland Ivi-shell.
Consensus: GRPC integration is the priority, but Wayland Ivi-shell support should remain for flexibility.
Marius requested a state diagram to better understand the architecture and interactions between components like ULA, ULA Node, and Unified HMI.
Application Development:
Panasonic will provide navigation and turn-by-turn applications.
Additional development (e.g., buttons for layout switching) will require collaboration with AGL developers.
Demo Preparation Timeline:
The proposed demos are not targeted for Embedded World due to time constraints.
Focus will be on preparing for the next AGL All Member Meeting (AMM) in Berlin.
RFC and Community Feedback:
Michele Paolino provided updates on the RFC for loopback features:
Security concerns raised by the community have been addressed.
Next steps include pushing updates to the AGL repository and continuing discussions with the community.
Miscellaneous:
Discussion on hardware requirements for demos (e.g., number of boards and outputs).
Marius Vlad highlighted the need to reuse existing code for GRPC integration to save time.
Action Items
Kenta Murakami (PAS):
Upload slides to the conference page and attach the state diagram to the Jira ticket for GRPC integration.
Provide additional details or clarifications on Unified HMI architecture as requested by Marius Vlad.
Marius Vlad:
Continue prototyping GRPC integration and provide feedback on missing information or challenges.
Walt Miner:
Finalize the schedule for upcoming events and ensure alignment on demo preparation timelines.
Michele Paolino (VOSYS):
Push updates to the AGL repository regarding loopback RFC and security improvements.
All Participants:
Prepare for the next AGL All Member Meeting in Berlin, with a focus on showcasing Unified HMI demos.

Key Discussion Points:
Architecture and Development Updates:
Kenta Murakami presented a revised architecture slide, proposing that the "Unified HMI Window Manager" may not be necessary due to gRPC compatibility with Go language.
Marius Vlad emphasized the need for a test component (AGL IVI Window Manager) to validate API connections and simulate demo requirements. This component is temporary and intended for testing purposes only.
The team discussed the importance of a testbed to validate data exchange between ULA Node and the compositor before finalizing implementation in the shell.
Demo and Benchmarking:
The current demo setup uses KVM to run Zephyr and containers for Linux-based applications.
A proposal was made to explore dual architecture:
One using Xen Hypervisor.
Another using KVM and non-hypervisor solutions.
The goal is to maintain a unified interface while supporting different backend implementations.
Xen Hypervisor Considerations:
Xen Hypervisor is seen as a strong candidate for production environments, especially in automotive use cases.
Challenges with Xen include limited support for graphics output (e.g., Virtio GPU).
Collaboration with ARM, Linaro, and Renesas was suggested to leverage existing work on Xen Hypervisor.
AMM (Automotive Grade Linux All Member Meeting) Preparation:
Michele Paolino's session is currently on the waiting list. Walt Miner will review the schedule and confirm availability.
Michele was asked to prepare slides summarizing achievements for potential inclusion in the keynote or STVG session.
Discussions at AMM will focus on the future direction of hypervisor and non-hypervisor solutions.
Future Work and Action Items:
The team discussed the possibility of a dual architecture approach:
Hypervisor-based solution using Xen.
Non-hypervisor solution using containers and KVM.
The importance of balancing committee member interests and technical feasibility was highlighted.
The need to address the graphics output limitations of Xen Hypervisor was noted.
Action Items:
Michele Paolino:
Prepare slides summarizing achievements for AMM and share them with Jerry.
Include options for dual architecture (Xen and KVM) in the presentation.
Marius Vlad:
Update the architecture diagram to clarify the testing and implementation process.
Continue working on the AGL IBI Window Manager as a testbed for validating API connections.
Jerry (PAS_趙健淙):
Coordinate discussions on Xen Hypervisor and KVM at AMM, including potential collaboration with ARM, Linaro, and Renesas.
Walt Miner:
Confirm Michele's session status for AMM and finalize the schedule.
All Members:
Continue discussions on dual architecture (Xen and KVM) and finalize the approach for Phase 4.
Prepare for in-depth discussions at the AMM regarding the future direction of hypervisor and non-hypervisor solutions.
