      1. Switching between multiple layout patterns using buttons.

      2. 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.

Key Discussion Points:

1. 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.

2. 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.

3. 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.

4. 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.

5. 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.
