Do It Faster: How We Supercharged Linux To Work With Blazing Fast ADCs for IIO - Trevor Gamblin, BayLibre

Wednesday August 27, 2025 09:00 - 09:40 CEST

Elicium 1

What does it take to support high-performance ADCs and DACs in the kernel? To get the most out of these devices, we need to make some significant overhauls to PWM and SPI subsystems, including adding pivotal new features such as SPI offload and PWM waveform to the upstream Linux kernel. This has ultimately led to adding support for dozens of ADC/DAC devices in the IIO subsystem and expanded the capabilities of those already there, allowing them to operate up to millions of samples per second without jitter. We'll give a high-level overview of how this project came about, the target hardware configurations, test equipment used, and methods to make it all happen, along with the challenges we overcame in the process. A "lessons learned" approach to this review and some possibilities for future work will round out the talk.

Powering Up: Lab Automation With Labgrid and CI - Tim Orling, Konsulko Group & Trevor Gamblin, BayLibre

Wednesday August 27, 2025 09:50 - 10:30 CEST

D201

How do you automate your day-to-day embedded software development workflow - if you do? In today's fast-moving world, automation is all-but-essential. In addition to development speed and efficiency, we need it to be confident that our changes are not breaking anything and to continuously keep up with upstream changes and security fixes. Toward this objective, we will explain how to get started with a GitLab runner for continuous integration, and combining it with Labgrid and pytest for automating testing on hardware at your desk. Our target device will be a BeaglePlay booting a Debian OS with the goal of a tight development loop for kernel drivers and devicetrees. We will also discuss how to incorporate that into a more "product" focused testing loop with the help of the Yocto Project. Most importantly, we'll explain why this is such a power-up for the developer by sharing our own experiences and how they've been improved by adopting the workflow we've described. After automating your personal development workflow, we’ll explore community initiatives like KernelCI that are using similar tools for automated builds & tests at scale.

Deploy AI in 20MB: Lightweight Containers for Open Source Developers - Miley Fu, Second State

Wednesday August 27, 2025 11:55 - 12:35 CEST

Emerald Room

Containerization has enabled powerful deployment workflows—but traditional Linux containers can be heavyweight, especially for LLMs or AI workloads on resource-restraint environments.

This session introduces WebAssembly as an alternative for deploying small, single-purpose AI functions. We’ll demonstrate how to build a simple AI service in Rust, compile it to Wasm, and compare the runtime footprint and deployment model with a traditional Python or Linux container-based equivalent. The focus will be on practical constraints: image size, memory use, startup time, and runtime isolation. We’ll also walk through running them (along open source LLMs) in sandboxed environments, even without root access, and why this matters for cross-platform efficient and secure deployment. The session is geared toward beginners who may already be familiar with Docker but are looking for faster, more portable alternatives to run open source LLMs in real-world environments.

Ideal for devs exploring open-source AI tooling, local-first agents, or edge inferencing.

How To Support Multiple Display Controllers With Different Interfaces on One SoC - Devarsh Thakkar, Texas Instruments & Aradhya Bhatia, Intel Corporation

Wednesday August 27, 2025 11:55 - 12:35 CEST

Elicium 1

Modern SoCs often integrate multiple display controllers to support advanced use-cases such as multi-display setups, content mirroring, or screen extension. These controllers typically support heterogeneous interfaces like DSI, HDMI, OLDI, or (e)DP to accommodate a wide range of panels and bridge devices. Taking TI’s AM62P SoC as an example-which includes two display controllers, a GPU, and multiple interfaces such as DSI, DPI/HDMI, and OLDI-this talk will cover the design considerations involved in enabling Linux DRM driver support for such systems. It will explore two key approaches for supporting multiple controllers: integrating both under a single DRM card versus exposing them as 2x separate DRM cards, along with their pros and cons. The talk will also highlight the architectural changes made to support dual OLDI bridges multiplexed between controllers, allowing either configurations–dual-link (from a single controller) or 2x single-link (from separate controllers). Finally, it will discuss the challenges with DSI bridge integration, particularly around crtc-encoder-bridge operation sequences, and how bridge APIs can be used to support custom sequences for bridge operations.

Thread: A Wireless IoT Networking Protocol That's Built on Open Source - Esko Dijk, IoTconsultancy.nl / Thread Group, Inc. & Saurabh Kumar, Samsung Research America

Wednesday August 27, 2025 11:55 - 12:35 CEST

Elicium 2

This talk will first introduce the audience to the Thread networking protocol: specifically designed to support Internet of Things (IoT) devices in homes and smart buildings. Thread standardizes wireless IPv6 communication between low-power, low-cost IoT devices, while also supporting end-to-end IP connectivity with other devices at home or on the Internet.

After the introduction we dive into more detail on OpenThread (https://openthread.io/), an open-source implementation of the Thread standard. Different OpenThread components are highlighted, and we’ll show what role each of these components plays: it may be from development of Thread-based consumer products, or testing new features for the Thread standard, to development of SDKs that Thread radio vendors offer. One specific component to highlight is the OpenThread Border Router, an embedded Linux based IoT device that orchestrates communication between Thread devices and other IPv6/IPv4 hosts.

We hope to show the open source community that OpenThread offers interesting opportunities to venture into IoT: covering a range of developer skillsets, platforms and languages.

Panel Discussion: Open Source in the Dutch (Semi) Public Sector: Strategies, Challenges & Digital Sovereignty - Jonas van den Bogaard, Alliander N.V.; Boris van Hoytema, Ministry of Interior Affairs and Kindom Relations, Marlena van Ooijen, Logius; Leon R

Wednesday August 27, 2025 11:55 - 12:35 CEST

G105

As open source grows in importance, more (semi)public organizations recognize its value. However, (semi)public organizations face unique challenges in adoption.

For organizations new to open source, developing a strategic approach and ensuring internal readiness can seem overwhelming. From engineering and technical teams to legal, finance, marketing, and executive leadership, aligning stakeholders on responsible and open source participation is critical—but not always straightforward. Many organizations address this by establishing an OSPO to create policies, provide training, and share best practices for open source adoption and contribution.

This panel brings together Open Source leaders from the Dutch (semi)public sector to discuss strategies for managing open source and fostering open source readiness. Panelists will share insights from their own open source journeys, offer practical guidance, and explore best practices for building open source engagement. The discussion will also highlight the role of open source in advancing Digital Sovereignty, ensuring organizations maintain control over their digital infrastructure while leveraging the power of open collaboration.

Building a Zephyr-Native Audio Framework With Sound Open Firmware - Iuliana Prodan, NXP Semiconductors

Wednesday August 27, 2025 15:05 - 15:45 CEST

D202

In this session, we will explore the audio stack and frameworks available in Zephyr, with a particular focus on Sound Open Firmware (SOF) - an open-source audio digital signal processing (DSP) firmware and SDK that provides essential infrastructure and tools for audio and signal processing development.

With the release of SOF 2.0, the project has integrated Zephyr RTOS, simplifying and improving its codebase. However, SOF remains tightly coupled to a Linux host OS driver, making it primarily suited for MPUs.

This talk will dive into decoupling SOF from Linux to enable standalone operation on MCUs, making it the go-to audio framework for Zephyr.

Key topics will include:

• Replacing Linux-based host communication

• Modifying SOF firmware to run without Linux-driven configuration

• Leveraging Zephyr drivers for hardware control

Join us to discuss the next steps in making SOF a truly Zephyr-native audio framework.

Towards Quality SBOMs: The OpenChain Telco SBOM Guide - Marc-Etienne Vargenau, Nokia

Wednesday August 27, 2025 16:20 - 17:00 CEST

G105

OpenChain is the international standard for open source license compliance programs ; it has been created by a joined effort of the community. The OpenChain project has several work groups. The Telco work group was formed to create a recommendation for an SBOM format to be exchanged between telecommunication companies, their suppliers and customers.

The result is the "OpenChain Telco SBOM Guide" that describes what a quality SBOM should contain and how and when it should be distributed. It includes industry standard requirements like "NTIA SBOM Minimum elements" and PURL. Although developed by telcos, it is generic and can be used by other industries.

The OpenChain Telco SBOM Guide is used by Nokia as a basis for its SBOM format. The talk will discuss lessons learned from implementing the Guide at Nokia. Putting the Guide in practice has led the community to provide a minor release 1.1.

Nokia provided an open source tool to validate SBOMs against the Guide. It allows to recursively validate linked SBOMs. It is available under Apache-2.0 license.

From Radar Echoes To Real-Time Recognition: Deep Learning on Another Planet an Open Source Workflow - Viktor Somogyi, Netwerk / HUN-REN / ESA

Wednesday August 27, 2025 16:20 - 17:00 CEST

TBA

What happens when you combine real radar images of Venus, a bunch of volcanoes, and deep learning? In this talk, I’ll walk you through a fully open-source machine learning pipeline that turns extraterrestrial data into structured scientific insights. Our goal is to automatically recognize geological formations like craters, ridges, or volcanoes on radar imagery — a bit like Google Maps, but for another planet.

The workflow starts with hand-labeled GeoJSON data in QGIS, then moves through preprocessing, training, and testing using PyTorch, scikit-learn, and AWS SageMaker — all running on Linux-based cloud infrastructure. This ESA (European Space Agency) funded scientific project is coordinated by the Hungarian Research Network (HUN-REN), and every part of it is powered by open tools and services.

Zephyr & Linux Devicetree, Similarities and Differences – Practical Guide To Boards, Shields and Con - Stephan Linz, Navimatix GmbH & Tobias Kästner, inovex GmbH

With the introduction of Devicetree translation into the Zephyr build process, not only was a proven hardware description language integrated as the state of the art, but also the door to a new art of metaprogramming was opened for the first time for deep embedded programming.

After a short introduction, this talk will take a practical look at the terms commonly used in Zephyr, such as boards, shields and connectors, explain their differences to familiar build and runtime processes from the Linux world and show the limits of the abstractions that can currently be realized with Zephyr. Simple examples for daily work will be presented, but also terms such as Nexus or Shield Stack will be defined in more detail.
