Agenda: 

  • Topic 1: VirtIO-loopback RFC

  • Topic 2: Unified HMI Application Discussion

  • Topic 2: Unified HMI GRPC I/F

Minutes

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:

        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.

    • 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

  1. 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.

  2. Marius Vlad:

    • Continue prototyping GRPC integration and provide feedback on missing information or challenges.

  3. Walt Miner:

    • Finalize the schedule for upcoming events and ensure alignment on demo preparation timelines.

  4. Michele Paolino (VOSYS):

    • Push updates to the AGL repository regarding loopback RFC and security improvements.

  5. All Participants:

    • Prepare for the next AGL All Member Meeting in Berlin, with a focus on showcasing Unified HMI demos.
