Linux Power Management Features & Their Interactions, Part 2 - Théo Lebrun, Bootlin

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

Elicium 2

Over time, many features have been introduced into the Linux kernel to tackle various Power Management related needs. Most features rely upon the device model to provide its features, making each feature in isolation have rather understandable behavior and straight forward APIs. Complexity can creep in however when those various features interact with each other.

Breadths is so wide that it takes two talk to cover features. This is a continuation talk expanding on last year's.

Topics targeted are system-wide suspend wakeup sources, device & generic power domains, the concept of latency tolerance (QoS), async PM and others.

A Journey To the Secure World of OPTEE From the Non-secure World of Linux - Manorit Chawdhry & Keerthy Jagadeesh, Texas Instruments

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

Elicium 2

OP-TEE is a Trusted Execution Environment (TEE) that serves as a companion to a non-secure Linux kernel running on an Arm processor. It operates on the secure side of ARM TrustZone and is one of several open-source operating systems compatible with it.

In this talk, we will explore

- Basics of TrustZone and basic introduction of OP-TEE

- Different types of trusted applications(TA) that OP-TEE provides

- Example usecases of TAs and which one to use for different usecases.

- Interaction of TAs ( and optee in general ) with the Linux

The talk will explain all this using an example application that allows writing and reading to/from the one-time programmable(OTP) efuses on Texas Instruments K3 platforms.

Modernizing Resource Management in Embedded Systems Using eBPF - Michał Wilczyński, Samsung Electronics

Wednesday August 27, 2025 11:00 - 11:40 CEST

Elicium 2

Embedded systems must carefully balance limited resources. This presentation shows how we used eBPF to improve resource management in TizenOS through two solutions: a new low-memory detection system and a dynamic cache tuner. Our eBPF-based low-memory detector significantly reduced false alarms while identifying problems earlier than traditional approaches. The cache tuner successfully improved I/O performance during disk-heavy workloads while automatically reducing memory pressure. Both solutions use eBPF to collect data with minimal overhead. Ill share implementation details, code examples, and test results to help others apply similar approaches to their embedded systems, contributing reusable patterns that can strengthen resource management across the embedded Linux ecosystem.

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.

Easily Generating Debian-Based Embedded Systems - Clara Kowalsky & Felix Mößbauer, Siemens AG

Wednesday August 27, 2025 14:10 - 14:50 CEST

Elicium 2

Debian ensures long-term stability and offers a wide range of packages that simplify software development. However, it lacks tools to efficiently create reproducible and customizable images as provided by Yocto. In this talk, we give an update on the open source build system Isar, which has been around since 2017 and combines the strengths of Debian and Yocto to create images for various x86, ARM64 and RISC-V boards.

Using the RPi4b as an example, we walk you through setting up the build environment, adding your application and flashing the image to the hardware. We illustrate new Isar features, such as the integration of the sstate cache. Furthermore, we give an outlook on enhancing your system with Secure Boot and Over-the-Air (OTA) firmware updates with swupdate, using the Isar layer from the LF Civil Infrastructure Platform project.

Setting up Real-time Ethernet and TSN With Linux: A 10-step Guide - Jan Altenberg, Open Source Automation Development Lab (OSADL) eG

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

Elicium 2

The Ethernet real-time evolution, partly driven by TSN standards, may represent an important step for building an open ecosystem for fieldbus communication. With more TSN capable hardware supported by Free and Open Source Software, this ecosystem seems to be almost complete – but still not very much in use. One reason may be the lack of support and the complexity of choosing and configuring the software. This presentation addresses this gap and presents a guide of how to set up real-time Ethernet communication on a Linux system. It includes a list of software components, configuration details of the network devices, routing of critical traffic and timely processing by the Linux kernel.

Software Defined Hardware on Heterogeneous SoCs Using OpenAMP - Peter Fecher, PHYTEC Messtechnik GmbH

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

Elicium 2

The growing complexity of modern embedded systems requires innovative approaches to make hardware more flexible and efficient to use. A concept for the software-controlled emulation of interfaces using technologies like Bit-banging, NXPs FlexIO or similar will be presented. The presented approach utilizes the integrated coprocessor of a heterogeneous SoC to achieve maximum efficiency and fulfil the corresponding real-time requirements.

With Zephyr RTOS and OpenAMP, seamless inter-processor communication is realized, allowing easy and modular integration into Linux. The prototype developed shows how software-defined approaches can improve flexibility of hardware adaptation in embedded systems.
