Automotive Grade Linux All Member Meeting Japan 2026

As software-defined vehicles become more complex, the industry needs common virtual device interfaces for faster development cycles and more reusable software assets.
This keynote highlights recent progress around VirtIO as a key enabler of open-source-based virtualization for automotive systems.
The presentation will cover industry momentum behind VirtIO, AGL’s ongoing expansion of VirtIO device support, and contributions around Unified HMI and the AGL SDV reference platform SoDeV.
It will also discuss the next step: extending virtualization beyond in-vehicle platforms by linking cloud-native development with simulated models and external systems, opening new possibilities for scalable SDV engineering and ecosystem collaboration.

2025 marked a turning point for Automotive Grade Linux (AGL) and the Japanese automotive open source community. Growing interest from the Japanese automotive industry, the launch of initiatives such as SoDeV and AGL Assessment Automation (AAA), and expanded activities targeting both the community and the industry created strong momentum for AGL in Japan.

This session looks back on the past year of the AGL Japan Community, highlighting what changed, why it mattered, and how these developments are reshaping AGL’s role in the Software Defined Vehicle era. We will review key developments in 2025, including the motivations behind SoDeV and AAA, and the evolution of community engagement through events, demos, and outreach.

Looking ahead to 2026, the session will share perspectives on where these initiatives are heading and what kinds of collaboration and contributions are needed to sustain this momentum. The goal is to clarify how companies and individual contributors can get involved and help shape the next phase of AGL together.

This session showcases how an open-source hypervisor like Xen can be analyzed and optimized in practice. By examining workload behavior in Linux guests together with Xen scheduler behavior, it highlights how an open-source stack enables informed and reliable performance tuning. The talk demonstrates Xen as a practical choice for environments where understanding, validating, and improving system behavior matter.

Unified HMI is a software-defined display virtualization platform based on VirtIO-GPU that enables such cross-SoC and cross-OS multi-display integration. Unified HMI helps developers reduce development complexity and accelerate practical multi-display HMI development on AGL.
 
This session presents the evolution of Unified HMI for 2026, focusing on dynamic layout control and easy integration for developers and integrators. We introduce updates to UHMI APIs that enable applications to be launched and dynamically moved in multi-display environments across AGL and Android, without complex configurations.

As part of the AGL SoDeV activities, we conducted an internship program linked to recruitment activities in Japanese companies, in which participants practiced contributing to open source software (OSS).

With the aim of incorporating it into the SoDeV system, we tackled the challenge of running virtio-gpio using Zephyr in a Xen environment.
The program was carried out over a two-month period, and the participants ultimately succeeded in submitting patches to the OSS community.

Through the practice of OSS activities within an internship, several challenges became apparent. These include the difficulty of defining appropriate technical tasks that fit within the limited duration of the internship, the risk caused by variations in the skill levels of participating students, the need to balance the program with recruitment objectives, and the high level of expertise required from mentors for effective OSS mentoring.

Nevertheless, the significance of this initiative is considerable. Beyond being a single case within Fujitsu, we report this practice with the expectation that it may contribute to the broader adoption of OSS-oriented internship programs among Japanese companies.

As the automotive industry rapidly transitions to Software-Defined Vehicles (SDVs), widespread SBOM usage is critical for improving transparency, security, and compliance across the supply chain. However, adoption faces significant barriers. OEMs and suppliers currently struggle with fragmented requirements, differing quality criteria, and unclear handling processes, leading to inefficiency and severe supplier fatigue.

To overcome these challenges, the OpenChain Automotive Work Group launched the Automotive SBOM Project. We are developing the "Automotive SBOM Specification" as a common guideline to ensure SBOM practices are practical, scalable, and meet shared quality criteria.

As an original proposer, I will introduce this specification's outline and share our latest community discussions on solving key adoption barriers. Most importantly, this session is a call for collaboration. I invite all stakeholders to join us. Let's work together to refine these guidelines, standardize our supply chain processes, and accelerate effective SBOM usage across the automotive ecosystem.

Introducing Arene Base, Woven by Toyota’s newly open-sourced foundational C++14 library for safety-critical automotive software, developed in line with AUTOSAR-style constraints such as avoiding exceptions and unbounded dynamic allocation. It provides non-allocating, non-throwing containers and backports of modern C++ features, including constexpr-friendly algorithms and utility types like span, optional, and variant, along with an optional partial implementation of the C++14 Standard Library to simplify integration on platforms where a suitable C++ standard library is not available.
