(Virtual) Lightning Talk: Full Workflow With West - Al Semjonovs, Google
West provides a great one place solution for building, testing, flashing, and managing repos. At Google, we've been working on new sub commands to help simplify developer workflow.  First we created the “west twister” subcommand. When working with multiple west projects, navigating to the correct path to twister can be cumbersome and sometimes the wrong one.  When you have a mismatch of code and twister from different projects, the test results will be inaccurate. The west twister command solves this problem by using west to identify the path to twister for the current project.  Second, we're working on a dependency manager for python based and native tools.  From the west manifest, we can store the current version of tools needed for the project and their dependencies.  Invoking  “west update” can query this data to install the needed changes.  Another west subcommand we're working on is "west push", which improves Zephyr Upstream workflow and pull request management when working with multiple branches that have dependencies on each other.

(Virtual) Lightning Talk: Tokenized Logging with Pigweed - Al Semjonovs, Google
For space saving, Zephyr’s logging subsystem can be enabled to provide a dictionary based logging system. This creates a JSON database file in the build directory which contains information to correctly parse log data.  This database file only works with the build it's generated with.  Other builds cannot use the same database file as strings are mapped to their address.  At Google, we’re opting to use Pigweeds (PW) tokenizer logging module.  Instead of mapping strings to addresses, PW tokenizer maps strings to a hash.  When log format strings stay the same between builds, the hash stays the same. Any new strings are appended to the hash database. Addresses are almost entirely unpredictable between builds.  This reduces friction for developers in viewing logs when making changes while also reducing image size. We’re working on making pigweed as an additional Zephyr module which can be linked in with KConfig options. The hash database will be updated and stored as an artifact of each build.

(Virtual) Shield Your Devices: The Strength of Open-Source Software and Hardware - Marouene Boubakri, NXP
The RISC-V software ecosystem is a rapidly growing community of developers and companies working to create software and tools for the RISC-V architecture. This includes operating systems, compilers, debuggers, and other software development tools, as well as libraries and middleware for specific applications. However, one limitation of the ecosystem is the lack of a fully trusted operating system for RISC-V being able to run on a Trusted Execution Environment (TEE) as companion to a features-rich operating system (rich OS), such as, Linux. This presentation aims to fill this gap by proposing a port of Open Portable Trusted Execution Environment (OP-TEE) to RISC-V with a fully compatible design and maximum reuse of existing Trusted Applications (TAs). The TA ecosystem has grown as a result of the transition from vendor-controlled, single purpose TEEs to open TEEs that host from multiple sources with various use-cases in mind. This created more robust and customized security used in a wide range of applications, varying from mobile, automotive, industrial to IoT to enabling technologies such as AI/machine learning and connectivity. This makes the project a core security project with the final goal of delivering enhanced security at a lower cost to devices based on RISC-V and Linux.

(Virtual) Debating Linux in Aerospace: Objections and Paths Forward - Steven H. VanderLeest, Boeing & Peter Brink, Underwriter Laboratories (UL)
Traditionally, safety-critical flight software used in aerospace is closed, proprietary code from a handful of commercial vendors. Although open-source software could provide several benefits, there are significant hurdles that prevent widespread adoption. First, we list some of the potential benefits of open source for safety-critical aerospace applications. Second, we present an overview of the key concepts and standards for flight software. Third, we identify the objections and concerns for using Linux as the avionics real-time operating system, which is software that generally needs the highest levels of assurance. For each objection, we suggest a possible path forward to address the concern.

(Virtual) AP Power Sequence Subsystem - Bernardo Salvador Perez Priego, Intel Corporation
This talk introduces a subsystem API in Zephyr to manage the ACPI power sleep states of a connected application processor (AP). Users of this API will be able to query and receive notifications upon AP power state transitions. The AP power sequence subsystem is built on Zephyr's State Machine Framework (SMF), providing flexibility for AP architecture, chipset, and application specific requirements. ACPI’s global state (G3) and its six sleep power states (S0, S1, S2, S3, S4, S5) are present within the state machine domain. All these ACPI states have three hierarchical levels: - Architecture: is the highest level of the hierarchy, SMF states at this level perform operations that are shared by all designs based on a specific AP CPU architecture. - Chipset: these SMF states drive the power of components and monitor power good signals that are required for a specific AP chipset. - Application: is the bottom level of the hierarchy and these SMF states are reserved for action handlers intended to address platform or application specific computations. Utility macros and functions are also provided to easily follow hierarchy early described. Allowing implementation to register state action handlers, and safely perform state transitions.

(Virtual) Distributed Embedded Systems Using Zephyr - Yuval Peress, Google
Embedded computing goes way beyond a single chip. In a given system, it’s likely that several tasks are running concurrently and interacting with each other. In most other computing disciplines these would be called micro-services. With the latest integration of Pigweed’s embedded RPC implementation, it’s now possible to imagine a similar concept in the embedded domain. In such a system design, it’ll be possible to define the task’s interface using a .proto file. During compile time, we can choose how we want the generated code to behave: local vs remote. Having this boundary enables applications to distribute computation across multiple microcontrollers.  During the talk, I’ll discuss the benefits of having a proto API boundary and the benefits of running the service locally vs remotely along with the overhead. Additionally, I’ll discuss the benefits of such a modular design on testing. Finally, we’ll walk through a sample application with 2 services. The sample will demonstrate the benefits of: 1. Being able to develop the services in parallel 2. Writing tests based on the API boundary (before writing code) 3. Being able to run the service remotely without additional engineering overhead and minimal performance/memory overhead

(Virtual) Integration of a CA Certificate Store Into Zephyr RTOS - Jared Baumann, T-Mobile USA
This presentation briefly covers a proposed CA certificate store for Zephyr RTOS. This addition to Zephyr could greatly improve the development process for IoT applications by allowing for the utilization of a large number of CA certificates in Zephyr without requiring manual management. The utility of such as system is obvious, as it would allow for the storage of many certificates for whenever they're needed, much like many modern operating systems. It should greatly improve developer experience for new developers entering the Zephyr ecosystem, particularly those with interest in IoT applications.

In connected devices with mixed-criticality deployment, virtual machine technology (i.e., hypervisor) enables secure isolation and management. Most of the existing mainstream commercial hypervisor solutions are closed-source, while the open-source Linux KVM solution is a non-real-time virtual machine. Based on ARM64 and Zephyr RTOS, we developed an embedded real-time virtual machine named ZVM (Zephyr-based Virtual Machine). We can start and run Linux OS and Zephyr RTOS in ZVM. The main functional modules for implementing ZVM include CPU virtualization, memory virtualization, interrupt virtualization, I/O virtualization, and timer virtualization. We completed the implementation, integration and optimization of each virtualization module. ZVM is an open source embedded real-time virtual machine with a good license.

(Virtual) Tutorial: Time-to-Market With Zephyr and Pigweed - Yuval Peress, Google
In my opinion, one of the greatest benefits of Zephyr is the ability to get an application up and running quickly and with little to no overhead. For fast paced start-ups this means being able to buy a Zephyr supported board off the shelf and building out a prototype. These benefits are highly synergistic with both the Pigweed library and emulated tests.  During the talk, I’ll take the audience through the process of building out an embedded application from the ground up using Zephyr + Pigweed while setting up testing infrastructure using emulators. Tooling includes: gRPC and HDLC encoding for communication Capturing events, logs, traces, and snapshots to gather information about the device on the field. Reducing image sizes with an extensible hash based string token database The audience will gain exposure to the various Pigweed tools and libraries available to them with a strong focus on features that should improve “time-to-market”.  See https://pigweed.dev/ for more information.

(Virtual) Mitigating Hackers with Hardening on Linux – An Overview for Developers, Focus on BoF (Buffer Overflow) - Kaiwan Billimoria, kaiwanTECH
Our modern society is largely an info-driven one; embedded / IoT products based on our beloved Linux thrive. There is, however, a huge gap; the need for better security on end-products. Hackers currently have a field day! This session helps participants understand why and where software vulnerabilities exist, while programming and after; what (Linux) OS and app Hardening techniques one can deploy; what tools and methodologies help prevent and mitigate security issues. This session is heavily biased toward developers working on embedded Linux on resource-constrained systems using the 'C' programming language, for both application (user) and kernel-space (drivers, custom kernel features), and the security challenges faced by them. The tutorial consists of 3 parts: Part 1: Security and Hacking Intro Part 2: Deep dive into (some) software vulnerabilities, their root causes; CPU ABI basics geared to understanding the process / thread stack layout; the working of the BoF attack vector Part 3: Modern OS Hardening Countermeasures (on Linux), for both userspace apps and kernel (drivers, custom code). To make these discussions practical, a quick code-level demo of a simple BoF vuln on an ARM VM / hardware board will be performed (with the relevant code & docs provided on GitHub).

Secure Boot: What Is It, and Do I Need It? - Fabio Tranchitella, Northern.tech
Secure boot is a term heavily used within connected devices and IoT in particular, but it can also apply for other computing devices such as laptops and smartphones. A lot of confusion exists around what “secure boot” means because some hardware vendors have named their own implementation the same, or some variation of it, even though the general term is commonly used for a more broad implementation. This makes it difficult to understand what secure boot is, and which elements can be interesting in a given context. This talk aims to clear up the confusion around secure boot, in particular covering implementations in connected devices and IoT, where secure boot is very relevant. In this talk we will: * Decompose secure boot: the different use cases and technologies involved * Demonstrate real-world threats and use cases where secure boot can prevent * Cover threats where secure boot cannot help * Provide market data on the status of implementation of secure boot in IoT * List key components that you need to worry about for supporting secure boot

Safety Certifying an Open Source Project: The Example of Xen - Stefano Stabellini, AMD & Bertrand Marquis, ARM
Safety is important to software everywhere human lives are at risk. In these environments, safety standards must be followed to minimize the risk to humans and to follow regulations. Safety standards such as ISO 26262 come with a series of requirements and processes that sometimes clash with well-established Open Source software development practices. How do we reconcile safety certifications and Open Source? This presentation will provide some insights to answer that question, using the Xen hypervisor as an example. Xen has a micro-kernel design and provides a virtualization solution for embedded and automotive while having a code base small enough to make certifications possible. This presentation will go through the changes to upstream processes that the Xen community adopted during the last 12 months to align community activities with safety-certification requirements. It will discuss any additional changes planned for the near future. The talk will also cover the latest updates from the Xen FuSa working group on MISRA C, traceability, testing, etc.

Build a Pump Monitor for Railway Applications with Zephyr OS - Oliver Völckers, BeST Berliner Sensortechnik GmbH & Jonas Remmert, Phytec Messtechnik GmbH
The system uses the nRF9160 SiP to track pump usage data and send it to the cloud via LTE-M/NB-IoT. The pump monitor features temperature, moisture, and pressure sensors, as well as an accelerometer. It performs pattern recognition to evaluate the pumping process and send an encoded assessment to a cloud server via MQTT. The system is being used by German railway operator Deutsche Bahn for monitoring wastewater tanks on high-speed trains. It currently runs maintenance-free for up to three months before battery recharge is needed.

This presentation, based on one given at the IoT-Congress Munich in October 2022, will dive deeper into the electronic and software architecture design. Furthermore it will be shown how Zephyr helped solving many challenges and offered significant advantages over other ecosystems such as vendor-exclusive SDKs. Key design decisions in hardware and firmware during the development of the system will be explained. Many of those design decisions are generally applicable in low power projects.

Going West: How We Develop and Maintain a Zephyr-based Microcontroller SDK - Carles Cufí, Nordic Semiconductor
Carles will be discussing the challenges and opportunities in developing, maintaining and distributing a Zephyr-based microcontroller SDK.

The talk will go over the work that Nordic has done over the past few years to develop a modern, scalable Software Development Kit (SDK) for all nRF microcontrollers that uses Zephyr Project's RTOS code and tools as its foundation.
In order to reach that point Nordic has made countless contributions to the Zephyr Project, both to enable the use cases that an SDK requires and also to improve the upstream project itself. Indeed part of the mission when building the SDK is also to ensure that the open source project thrives and becomes the de-facto standard for open source MCU RTOS.

A lot of work was also required downstream, where new processes had to be established within the company to make it possible to work in cooperation with the open source projects, new tooling had to be developed to deal with forks, new approaches for contribution and code review had to be defined, and all this with a small team, aptly named Vestavind (western wind in Norwegian), coordinating the interaction between the projects and the commercial offering.

Secure Virtualization for MCUs Using Wasm - Toni Bofarull, Midokura (Sony Group)
IoT devices have traditionally been developed using a monolithic approach, with firmware written by a single vendor and infrequent updates. With the increasing connectivity of IoT devices to the cloud, it is now possible for these devices to be customized and updated frequently. However, the current software development paradigm for IoT devices has not kept pace. We are preparing to open source Wedge, a virtualization platform for IoT devices based on WebAssembly. Wedge works together with IoT platforms, such as ThingsBoard, AWS IoT, etc, to manage the lifecycle of applications on the IoT device. Wedge also provides various primitives for apps to use, and SDKs in multiple languages. Wedge uses AoT (ahead of time) compilation, done securely in the cloud, to optimize execution. On top of Wedge, we have developed a programming paradigm called Vision Sensing Pipeline for sensor data processing at the edge. Using information gathered from the IoT platform, the cloud based Sensing Pipeline Service automatically specializes the modules for the target devices. Developers never need to care about the architecture or exact capabilities of the devices. On top of the REST API, we have also added a visual programming interface, inspired by Node-RED. A brief demo will be shown.

How Eclipse Oniro Uses Zephyr – Lessons Learned - Stefan Schmidt, Huawei Technologies
The Eclipse Oniro project is built around the premise to support different kernels. The idea to run on devices big and small does mean it supports Linux as well as RTOS systems, with Zephyr being the one most actively used. In this talk Stefan will describe the different areas where Zephyr is used in Eclipse Oniro and how. The perspective will be as a user and consumer of Zephyr with needs for integration, stability and maintenance, but also new features and bug fixes. Stefan will show the lessons learned on the following technical use cases: Building Zephyr through meta-zephyr with Yocto/OE. Usage and configuration of functionality like OpenThread, CoAP and LVGL. Running a CoAP based project with a shared code base between Zephyr and Linux. Zephyr modules to integrate technologies so far not supported in upstream (e.g. Matter, OpenHarmony). An IP compliance toolchain to allow manual audits and final SBOM generation for images. This all is being stitched together by upstreaming fixes and new functionality, reporting bugs, backporting changes to LTS releases and doing product integration as final step.

Porting an AI Powered Wearable Health Monitor to Zephyr on Open Hardware - Szymon Duchniewicz, Avanade & Jakub Duchniewicz, Tietoevry
To RTOS or not to RTOS? Szymon and Jakub will introduce obstacles they faced and decisions behind moving a closed-source single-threaded wearable health monitor to an RTOS, open-hardware based system with an AI model deployed on a Field-Programmable Gate Array (FPGA). They will share tips on how to get started with Zephyr development, when and why to build a system using an RTOS. They will also share best practices and experiences on deploying a Machine Learning model to an embedded FPGA and interacting with it from Zephyr OS.  The project dissected in this talk uses QuickLogic's and Antmicro's QuickFeather board, powered by Open Hardware EOS S3 System on Chip. The Machine Learning Model is deployed using TensorFlow Lite and then integrated using an open source FPGA toolchain. Device collects data from an SPO2 sensor that is parsed by Zephyr at runtime and finally passed to the model deployed on the FPGA for inference. The results are then returned to the Zephyr RTOS and displayed on a small OLED screen.  The model is trained using open source data pertaining to blood pressure estimation based on SPO2 levels and is tailored specifically for deployment in embedded scenarios.

System Devicetree Support in Zephyr - Marti Bolivar, Nordic Semiconductor
Zephyr's support for AMP SoCs... works, but has several well-known usability problems due to workarounds for deficiencies in our hardware support features at the following layers: - devicetree - hardware model - build system This talk will introduce the system devicetree specification and its role in solving some of these problems. System Devicetree is an extension of the standard Devicetree Specification. Its main extensions to the base specification allow simultaneous representation of multiple CPU clusters within a heterogenous SoC, along with their individual memory maps, memory partitions for different executable images, and peripheral assignments. The main goals of this talk are to define the problems being solved, the reasons why our current build system infrastructure doesn't suffice, and discuss where system devicetree can help. We will also cover the current status of ongoing work to support system devicetree in the Zephyr build system.

Building an Open Source Smartwatch Using Zephyr - Jakob Krantz, u-blox
In this talk, Jakob will speak about his open source smartwatch, ZSWatch. The project includes all parts necessary to build a smartwatch: hardware, software, and mechanical parts. Additionally, Jakob will go through his experience of realizing this using Zephyr and talk about the advantages, the struggles, and the lessons learned. Software is a big part of a smartwatch and Jakob will talk about how Zephyr makes the interaction between human and hardware easier. But with only software there is no smartwatch. Aspects such as choosing the correct components are just as important, did Zephyr influence the choice of components? There will be a showcase of the internal design to help and encourage new contributors to the project. The project is relatively new and not very mature, meaning it will likely change and Jakob will share some thoughts and ideas about the future. Jakob will also talk about the background and history of the project, he may even answer the common question, why?

Reworking the Zephyr Clock Control Subsystem - Moritz Fischer, Google
The Zephyr DT based clock description works for a subset of existing drivers that fall broadly into two categories: Those supporting input clocks with compile-time known frequencies and those that use the clock control API to configure clocks. In this panel after briefly describing the status quo, and attempts I made at fixing the status quo, I'd like to have a discussion with the community on how we can move forward unifying the API such that all drivers can work with both fixed-clocks and dynamic clocks by making Zephyr's clock control API look and behave more like Linux' clock subsystem.

Porting of a Static Partitioning Hypervisor to Arm’s Cortex-R52 - José Martins & Sandro Pinto, University of Minho
E/E architectures are evolving toward centralizing computing resources. As functions are consolidated into zonal controllers, automotive manufacturers rely on virtualization technology to provide the freedom from interference required for workloads with different safety integrity levels. Under this light, Arm unveiled Cortex-R52, the first processor to implement the MPU-based Armv8-R architecture endowed with virtualization support and specifically designed for real-time systems, which is already finding its way to several platforms on the market. The speakers will share their experience porting the Bao static partitioning hypervisor to Cortex-R52 platforms. Bao is an emerging player in the open-source hypervisor space, being specifically designed for mixed-criticality systems. This talk will first describe Armv8-R, focusing on its virtualization support, and contrast it with Armv8-A. While doing so, it will highlight the main challenges of porting Bao to this new architecture. Then, it will describe MPU-based virtualization use cases and how these are configured and set up. Finally, it will conclude with the still open issues facing such systems and a small live demo of Bao running multiple virtual machines on a Cortex-R52 platform.

brewce: Brewing Beer with Zephyr, Android and Thingsboard - Christian Hirsch
Beer is one of the oldest known cultural beverages. Its main ingredients are water, (barley) malt, hop and yeast. The process of brewing beer is well-known and in order to dissolve the starch from the malt into the water, also called mashing, the malt and water mixture is heated up to specific temperatures that need to be hold for a certain amount of time. This gives the enzymes in the malt the ability to break up the starch to dissolve it. Hobby brewers normally use home brew kits and commercially available equipment to brew their own beer. In this talk, Christian Hirsch presents brewce: a setup of home-brewed electronics for home brewing beer. brewce consists of four devices: a modified induction cooker, a temperature sensor, a pump control and a smartphone. The induction cooker was reverse engineered and equipped with some electronics which runs the Zephyr RTOS and which lets one control it via Bluetooth Low Energy (BLE).

Manifests: Project Sanity in the Ever-Changing Zephyr World - Mike Szczys, Golioth
Zephyr has a robust “manifest” system that you can use to lock each software component in your project to a specific branch, tag, or commit. At first glance it may not sound like much, but if you use it wisely, every project will build without fail whether it’s been a week, a month, a year, or a decade since you last compiled. The update cycle is (thankfully) very quick with Zephyr. Users who install one central version of Zephyr and use it for several different projects are bound to encounter version incompatibilities when those projects do not update at the same pace as the RTOS. This is the reality of any rapidly improving software ecosystem, and I’ll show how to use the manifest system so your project builds are always stable. This talk covers how to create project-level manifest files that install a dedicated copy of Zephyr and all other library dependencies. Once that's in place we'll use the manifest to pull in your own custom board definitions, out-of-tree helper files, and some other goodies that keep your firmware stable, modular, and easy to upgrade, all at the same time.

Lightning Talk: The AGL Wayland Compositor - Marius Vlad, Collabora
Automakers using Wayland compositor have been relying for some time now on weston, and particularly on ivi-shell, to provide them with the means to develop and run an IVI system.  Marius Vlad will provide a short overview about Wayland, about the Wayland compositor in AGL and how it is being used without the traditional ivi-shell.  Still based on libweston, similarly to weston, the AGL Wayland compositor instead relies on the more modern, widely adopted xdg-shell, which all major toolkits support, and in the same time, still retain the functionality required by an IVI system.

Building Highly Scalable Edge Computing with Project Akri and WebAssembly - Shivay Lamba & Rishit Dagli, University of Toronto
Edge computing is becoming increasingly popular for applications that require low latency and high bandwidth. However, building edge computing infrastructure that is both scalable and cost-effective can be challenging. In this talk, we will explore how Project Akri and WebAssembly can be used together to build highly scalable edge computing solutions. We will start by introducing Project Akri, an open-source project that provides a standard way to discover and interact with IoT devices at the edge of the network. We will then discuss how WebAssembly, a low-level bytecode format, can be used to run code at the edge of the network, providing a lightweight and portable runtime environment for edge applications. We will also cover some use cases where Project Akri and WebAssembly can be used together, such as building machine learning models that can run on edge devices or processing sensor data in real-time. Finally, we will demonstrate how to build a scalable edge computing solution using these technologies and share some best practices and lessons learned. Attendees of this talk will gain a better understanding of how Project Akri and WebAssembly can be used together to build scalable and cost-effective edge computing solutions

New USB Device Class API Introduction - Johann Fischer, Nordic Semiconductor ASA
As part of the experimental USB support, a new device stack has been added to the Zephyr RTOS since version 3.3.0. Existing implementations of the USB classes (or functions) will be ported to the new USB device support (porting should be completed by presentation time). The USB device stack itself does not provide any useful functionality. The functionality can be provided by a class implementation like CDC ACM. There are USB-IF class specifications, like CDC ACM, or third-party specifications, like the Bluetooth HCI transport layer. New USB device support has a common API to interface with class implementations. A vendor-specific class or function must also use this API. The API will be mandatory for all new implementations. The stack also has management functions, such as adding or removing a class instance to or from a configuration at runtime. Johann will give an introduction to the new USB device class API in USB support, show how to implement a simple function that supports multiple instances, and briefly describe the API. The author will also cover relevant differences and features in the new USB device support.

Lightning Talk: SWUpdate Over CAN Bus - Can It? - Stefano Babic, DENX
Embedded Linux will be more used in automotive, and even ECUs based on simpler microcontrollers are starting to be exchanged with more sophisticated processors with Linux as OS. Software is becoming complex, and the size of the firmware increases. On the other side, even if other network technologies (LTE, Wireless, etc.) are making the first steps into vehicles, the primary bus for the communication is CAN (Controller Area Network), with limitations about transfer size and low bandwidth. This talk is the description of the journey done by the author about how to implement an update mechanism using SWUpdate to upgrade an ECU over the CAN bus, showing which limitations we must face and what can be done in future.

Zephyr Onboarding in 30 Seconds - Methods and Experiments During Zephyr Training - Chris Gammell, Golioth
New users struggled with the Zephyr toolchain: this is not opinion, it is a fact borne out in many past training sessions. Getting the toolchain installed and configured is a technical hurdle at the beginning of any training. While there are talks that might propose solutions in the long term, this talk is about how to do training with Zephyr as it exists today. The wide variety of user backgrounds, environments, and target hardware makes this a challenge, and continues to prevent bringing new users into the fold. These challenges multiply if attempting to train people in remote locations. This talk will cover experiments done to improve training environments and the best practices that were discovered. These include things like containerized deployment, browser based compilation, important aspects of test hardware, training documentation needs, ways to engage remote users, and more. As an attendee of this talk, you will learn what works for new users, potential pitfalls to watch out for, and how you can train up members of your organization to become Zephyr power users.

OTA DFU Without Compromise - Brandon Satrom, Blues Wireless
Over The Air Device Firmware Update is one of the most-desired features for any IoT device management solution. In a world where all solutions are cloud-connected, DFU is a table stakes feature. But modern DFU approaches are brittle, and developers are forced to choose between either an "OS DFU" approach, in which a vendor solves the DFU problem end-to-end within the kernel, while specifying a very narrow choice of hardware, language, and IDE; or "Co-operative DFU," in which a vendor provides a cloud service to securely host firmware images and transport onto the device, but in which the "last mile" of the update process is the developer’s responsibility. Both methods can be made reliable, but are risky and can be inadvertently rendered nonfunctional by an errant 'infinite loop,' memory or flash overwrite, or bad interrupt handler. What if there was a third way? An approach for performing firmware updates "from the outside" without MCU involvement? An approach that can update firmware regardless of RTOS or language, and can even be used to switch between them? In this session, Brandon Satrom will introduce such an approach, and demonstrate how this capability allows developers more choice of host, language, and RTOS, without sacrificing the stability end-to-end DFU.

How I Fell in Love with Zephyr – a System Architect’s Tale - Tobias Kästner, UL Method Park & Stephan Linz, Navimatix GmbH
Tobias Kästner designs system and software architectures for medical devices for more than ten years. In this time he has seen and suffered through a lot of woes and problems, stemming from decades-old development procedures and ineffective communications within product development teams. Worse yet, many persistent beliefs about how projects ought to be run have become completely inappropriate for today's connected and ever faster moving world. Having followed Zephyr ever since its 1.10 release, the speaker has been using it in numerous projects collecting a considerable amount of experience to share. In his talk he will explain what profound impact technologies such as Kconfig or the Device tree have on the collaboration of hardware and software developers alike. Being also an advocate of model based systems engineering Tobias will use examples from his real-world projects to show how system models can inform downstream engineering activities. Thanks to Zephyr's many clever design decisions, collaboration can be made more effective and the risks of costly misunderstandings can be significantly reduced. The talk concludes with some ideas what the future might hold and what still needs to be done for the Zephyr project to succeed in the medical device and similar industries.

Open Source to the Core: The CORE-V MCU - Frédéric Desbiens, Eclipse Foundation
Open source has transformed the way we build and consume software. And yet, the computers we run our software on are the realm of proprietary technology. The recent emergence of the RISC-V instruction set was a first step to challenging the status quo. However, while the instruction set is open source, the chips that leverage it have been proprietary. That is, up to now. The CORE-V Microcontroller from the OpenHW Group changes that. Based on an open-source 32-bit four-stage RISC-V core, the MCU offers a rich set of peripherals, an embedded FPGA, and much more. In this presentation, you will learn everything there is to know about the CORE-V MCU and OpenHW Group. You will also discover how the OpenHW Group and the Eclipse Foundation are building a comprehensive RISC-V ecosystem together. Finally, you will see how to leverage RTOSes and the wider ecosystem of Eclipse IoT components on the CORE-V MCU.

having a portfolio of products with different PCBs does not necessarily mean that one needs to manage a different code base repository for each PCB. for the products in the portfolio that follow the same general functionality of sensor sampling, streaming, maybe some edge computing and transmitting of the data, one can actually build one common and configurable code base that does not care on which PCB it runs on. here is a blog i wrote on the topic: https://medium.com/augury-research-and-development/insights-on-the-re-architecting-to-a-single-firmware-codebase-running-on-different-hardwares-dbbbbcc3aaae

The Zephyr Project Security Overview, Progress, and Status - David Brown, Linaro & Flavio Ceolin, Intel
As more and more devices become connected, security of these devices is becoming more and more visible. With an increase in governmental standards regarding security of devices sold to consumers, the security of devices built using Zephyr is becoming ever more important. David and Flavio are the security chair, and architect for the Zephyr project. This talk will give an overview of our security journey, so far, what is being done now to improve the security of the project, and where we hope to go. The focus will be on the idea of a security vulnerability: what happens when a vulnerability is reported, how it gets fixed, tracked, and who is notified and when, ending with the public disclosure through the CVE system.

Keynote: Organising the Hardware Ecosystem with Open Source: Antmicro's Visual System Designer - Michael Gielda, Co-Founder, Antmicro
The landscape of hardware offers plentiful options in terms of SoCs, sensors, cameras and boards, but uneven availability, coverage in software and tools and lack of makes the experience of a product developer very unpredictable. Luckily, the Zephyr RTOS is emerging as a great equalizer of hardware, reflecting the hierarchies inherently present in hardware offerings with code, device trees and configs.

Combining this structured data with Renode, Antmicro’s open source, embedded hardware simulator, we built the Zephyr Dashboard, a massive CI testing exercise for hundreds of Zephyr targets, and Renodepedia, a portal to navigate the platforms, their components and data we have about them as well recreate the results. Systematizing this substantial amount of data lets us observe patterns that help build embedded systems more efficiently and contribute back to Zephyr to introduce even more structure and order, and we are working on expanding this to cover U-Boot and Linux.

Based entirely on open source tools, our hardware design process is also a pattern-matching and data organization exercise - and led to creating the Antmicro Open Hardware Portal, focused around and feeding our growing open source database of KiCad footprints, Blender 3D models and open hardware KiCad designs.

With all the data systematized through Renodepedia and the Open Hardware Portal, Antmicro is now developing an open source Visual System Designer platform which helps navigate the complexity of the hardware landscape by building system block diagrams from a library of well-defined components.

Visual System Designer can be described as an ultimate software/hardware resource - providing developers, product owners, business and marketing teams with a customizable, visual representation of real-world embedded platforms which can be simulated with Renode and seeded with software such as Zephyr or Linux. The tool can serve as a common interface between hardware and software teams and is already now being used to uncover even more patterns that have previously gone unnoticed.

Finding the Best Block Filesystem for Your Embedded Linux System - Michael Opdenacker, Bootlin
It can be difficult to find the most appropriate filesystem for your embedded system's eMMC or SD card storage. You can benchmark your system with each of them, but it can be time consuming. In this talk, we will compare all the actively maintained block filesystems supported in the Linux kernel: ext2, ext4, xfs, btrfs, f2fs, squashfs and erofs. Each of them will be properly introduced, with its basic design principles and main features. We will then compare each filesystem in terms of kernel module size and load time, filesystem mount time (important for boot time), filesystem size, as well as read and write performance on a few simple scenarios. We will also look for the best compression algorithms for filesystems with compression options. Performance comparisons will be run both on a 32 bit ARM board and on a 64 bit ARM one, both using a fast SD card as storage device. Filesystem performance can really depend on the benchmark, on your storage and on your CPU, so no universal results should be expected. However, you will learn what the best solution is in specific hardware configurations and testcases. No AI will be used to prepare, write this presentation and answer your questions. Only a human brain with 20 years of experience with Embedded Linux.

Reproducible System Composition Combining Linux, Xen & Zephyr on One Embedded Hardware - Philipp Ahmann & Thomas Mittelstädt, Robert Bosch GmbH
Looking at system architectures for complex embedded systems, similarities can be observed across various industries. Beside a rich OS (such as Linux), often an RTOS and virtualization or containers are involved. However, when it comes to prototyping such systems, the existing guidelines are limited and reproducing demos is hard and time consuming. The ELISA project’s systems working group focuses on creating an exemplary system architecture using Linux (like from AGL, CIP or APERTIS), Xen and Zephyr in a reproducible form. This includes step-by-step documentation for users on different expert levels and various entry points to approach these systems. The results of this activity are presented and shared as part of the talk. Additionally, an outlook to further work is provided, which includes picking up new requirements such as a system SBOM. The demand for strong interaction and collaboration among various open source projects will also be shortly addressed in this talk. Finally, the talk gets rounded up by showcasing the system implementation state. The demonstrated example is based on embedded automotive hardware and facilitates the usage of the AGL reference stack along with Xen and Zephyr.

The Resurrection of Ureadahead and Speeding up the Boot Process and Preloading Applications - Steven Rostedt, Google
The ureadahead application was created by Ubuntu to help speed up the boot process by tracing the applications during boot and seeing what they opened and using that information to preload the application's data on subsequent boots. But this ureadahead had some failings. The first of which was it relied on trace events that were rejected by the upstream Linux kernel maintainers. This meant the only way that you could use this application was to modify your running kernel. Another problem was that its main developer left Ubuntu in 2009 and very little has been done to maintain it. As time went on, it failed to do what it was meant to and was finally abandoned as it did not show any more improvement. Google has been maintaining a version in ChromeOS, and I have decided to start rewriting it and making it work with the existing trace events, removing the need for modifying the kernel. This talk will explain what ureadahead use to do as well as what I have done to improve it. Then a discussion will continue on how to use it and where it can be improved. The idea is that enough information can be shared in this talk that a good discussion on enhancements to ureadahead can carry over to the evening events.

Introducing a New Zephyr Sensing Subsystem
The Zephyr sensor driver API has existed since the very early days of the Zephyr Project and grown to over 100 driver implementations in more recent releases, supporting a variety of sensor types (accelerometers, magnetometers, temperature sensors, and more). A proposed new sensing subsystem builds upon the sensor driver API to add sensor hub functionality, arbitrating sensor configuration (sample rate, sensitivity) and managing data delivery to multiple clients in a Zephyr application. This talk will cover the architecture and design of the new sensing subsystem, as well as Intel's use-cases in client computing platforms.

Boot to Cloud Security Considerations with IoT - Kevin Townsend, Linaro
Designing secure IoT systems for resource-constrained embedded systems is a challenge, not because of the limited resources available, but because security needs to be considered from an end-to-end perspective. This means planning for: - A secure boot and firmware update process - The secure flow of data through the system - How do I know the data is trustworthy and hasn't been tampered with? - How do I know that this comes from the device it claims to? - How can I limit visibility of sensitive data? - Reliable device authentication - Secret management - Secure connectivity to public/private cloud servers Embedded developers can no longer limit themselves to one specific silo, and need to have basic skills and an understanding of the entire end-to-end, boot-to-cloud and security landscape to make the right design choices to produce a minimally secure system. This presentation tries to lay down some of those key requirements and design choices, and makes suggestions about best practices to follow based on open source software and open standards. This includes generating device-bound, storage-free private keys and UUIDs, mutual TLS, how to encode and transmit data securely and reliably, and bootstrap and X.509 certificate management requirements.

USB Device Support in Zephyr RTOS from the Application Perspective - Johann Fischer, Nordic Semiconductor ASA
Zephyr RTOS has an implementation of USB device support pretty much from the beginning. Apart from direct use in the user application, various subsystems in the Zephyr RTOS also make use of device support. Since version v.3.3.0 there is also a new device stack as part of the experimental USB support. Johann will give an overview of USB device support in the Zephyr RTOS from an application perspective. The author will also cover the differences and features in the new experimental support. The presentation will start with configuring USB device support, how to select the desired features (classes) and how to enable USB device support. Johann will give a step-by-step insight into the different USB class implementations and go into their peculiarities and how they work in or with other subsystems. Author will explain how and why some functions are described and configured via the device tree and others are not. Special attention will be given to the configuration and use of the CDC ACM class.

MediaTek Upstreaming: From Bring-up to Test Coverage - AngeloGioacchino Del Regno, Collabora
Writing Linux kernel code for new IP in new SoCs may not always be trivial. Making sure that your code complies with the high-quality standards required upstream is sometimes challenging, but ensuring that it will not create regressions on other versions of already supported hardware in the same driver is an entire story on its own.

Kernel engineers strive to provide state-of-the-art implementations and having to perform complex manual tests on multiple platforms, sometimes even for one-liners, highly affects delivery time: this is one of the reasons why downstream kernels become the preferred development route.

In this session, I will share a real-life example of how I upstreamed multiple Chromebooks (and a smartphone!) featuring different MediaTek SoCs: the scripts and tools that I used, the addition of KernelCI to my regular development workflow, how it helped me to catch bugs and save time, and why - and how - you can run ARM64 Chromebooks on the latest, bleeding-edge, linux-next kernels with Debian, ArchLinux, or even Chromium OS as the cherry on top.

- collect & analyze all file accesses: find paths of (missing?) config files and shared libraries
- get full list of all executed processes with command line, environment etc., e.g. to analyze complex shell scripts or make/build environments
- collect RT timing information, about process execution, file accesses or network traffic -- using this timing info you can reply load/access patterns you captured from real world testings/measurements.

Provisioning devices is one of the most important final steps that you need to complete before deploying your products out into the world. Fortunately Zephyr makes it simple to get devices set up with certificates, pre-shared keys and more. Specifically for this talk, we'll discuss how we provision our Nordic nRF9160 based devices across different customer projects. We'll discuss some concepts like Zephyr's shell and settings APIs. We'll also touch on writing and running utilities that interface with the device. In the end the attendee will come away with different methods that they can do to make provisioning as painless as possible.

Running Zephyr RTOS on Cadence® Tensilica® HiFi 4 DSP - Iuliana Prodan, NXP
Running Zephyr on Arm® Cortex®- A or Cortex®-M cores is widely discussed and there are many examples on how to implement it. However, many Cortex®-based MCUs and MPUs are choosing to also incorporate on-chip DSPs to offload computationally-intensive tasks. The Cadence Tensilica HiFi 4 DSP is one such example of a high-performance embedded digital signal processor (DSP) optimized for audio, voice or neural network processing. This presentation will highlight how to harness the power processing of the DSP by running Zephyr RTOS on the DSP, while running Linux® OS on the main Cortex®-A core. This presentation will cover simple and more complex examples, such as “hello_world”, IPC samples and Sound Open Firmware. Attendees will learn how to launch the application on the HiFi4 DSP, how the HiFi4 DSP and main core communicate together, how to get the output of the application and how to debug. For all the examples, existing drivers and/or frameworks from Linux® OS and Zephyr RTOS will be used. This presentation will go into detail about changes that can be made in Linux® OS and Zephyr RTOS code so that both operating systems can be jointly used across various applications.

Toolchain Options in 2023: What's New in Compilers and Libcs? - Bernhard Rosenkränzer, BayLibre
Up until not too long ago, it was clear what you had to do when building a toolchain for your new system (embedded or otherwise) -- build GNU binutils, a minimal version of gcc, then glibc, then a more full-featured version of gcc for the target. In more recent years, other options have come up and started to receive some attention: LLVM and elfutils have alternative implementations of binutils, mold is getting ready as a viable alternative to BFD ld, gold and lld, clang can replace gcc almost everywhere (and in some situations, even tcc might be sufficient), and there's numerous libc implementations to choose from. Many SoCs come with a platform SDK including a toolchain - but is that always the best option? (Spoiler: The answer is a two-letter word) This talk shows the available options, their unique advantages and drawbacks, and some pitfalls you may want to be aware of before making your choice for the toolchain used with your next embedded system.

Community Fueled OTA for Zephyr (and Other µCs) - Josef Holzmayr, Mender.io
Getting updates out to connected devices is becoming a common requirement, and there are numerous ways and solutions to archive that. When it comes to RTOS or even bare metal µC platforms, their flexibility is a key concern. Does a solution: - Encourage third party clients and extensions? - Support arbitrary architectures and payloads? - Have open interfaces for CI/CD pipeline integration? - Allow self-hosting? Taking this wishlist, Mender community member Joël Guittet set out to create an implementation for a development board he happened to have lying around: the ESP32. Just a few days later he came up with a proof of concept, and the properly documented and licensed release followed suit. Yet he didn’t stop there. “What about Zephyr?” he asked, and went back to action. It wouldn’t take long again. In early February 2023, Joël opened a new repository on GitHub. The name: “mender-stm32l4a6-zephyr-example” This presentation tells the story of community engagement, how it makes things happen, and the value of being committed to open source. And the value of opening your mind beyond what you know.

Management of IoT TinyML Devices - Mieszko Mieruński, AVSystem
As deployment of TinyML algorithms on resource-constrained embedded devices is relatively cheap in comparison to cloud based ML solutions, we experience a boom of TinyML solutions in versatile use cases including security systems, intelligent lighting, wildlife conservation, early warnings about system failure detection and many others. Despite the quickly growing number of available TinyML projects, existing solutions for MLOps are not well integrated with each other and the rest of the IoT ecosystem. As a result, IoT solution providers are required to integrate multiple communication stacks into their devices, which is challenging for resource-constrained devices. These challenges can be addressed by integration of the LwM2M communication protocol with TinyML solutions. In such a scenario, we obtain a single communication stack that multiplexes OTA updates, telemetry data collection and device management on a single network connection. Mieszko will talk about integration of Edge Impulse ML with LwM2M, how the solution can be standardized, what are the gains of the approach and showcase a demonstration of the whole TinyML operations flow based on Zephyr RTOS to detect system anomalies and failures.

Enabling Sound Open Firmware on Arm® Cortex®-a Based Devices Using Zephyr RTOS - Daniel Baluta, NXP
Sound Open Firmware is an open source audio DSP firmware that provides firmware source code, tools, and debug capabilities to enable developers to add more value and customization to their projects. While initially developed on the Cadence® Tensilica® HiFi 4 DSP, the firmware has a modular and generic codebase that can be ported to different architectures. This presentation will focus on how to move this code to newer Cortex-A devices that don’t incorporate a separate DSP. The task starts with using Jailhouse hypervisor to reserve the Arm Cortex-A core to run the Sound Open Firmware as an application inside Zephyr RTOS. This presentation will detail the general solution involving running Linux OS and Zephyr RTOS on separate ARM® Cortex- A cores with the help of Jailhouse hypervisor. The presentation will focus on the process of enabling Zephyr on a Cortex-A55 core, and then integrating Sound Open Firmware applications.

Leveraging Compiler Code Instrumentation for Zephyr Tracing & Profiling Tools - Gustavo Romero & Kevin Townsend, Linaro
Most profiling and tracing features in Zephyr today either depend on proprietary and expensive tooling, or have significant platform limitations. For instance, Segger's SystemView, which requires J-Link, or gprof, which only supports a few platforms -- often emulated -- like native_posix, and native_posix_64 platforms, with no timestamp data associated with events.

Clang and GCC compilers provide entry/exit instrumentation for functions via the -finstrumentation-functions flag. This flag allows for a specific function to be called on any function entry/exit event, which we can leverage to generate code tracing and profiling information.

In this presentation, the authors propose and demonstrate a platform, tooling, and arch-neutral subsystem based on compiler function instrumentation for Zephyr. Possible ways to display the collected data, like flame graphs, are also presented.

The new tool can be used for:

A) Tracing, meaning it can be used to generate an instrumented call graph, including timestamps, limited by the number of entry/exit events that can fit into a memory buffer. 

B) Profiling, meaning it can be used to calculate the overall runtime spent in the top 'n' functions, plus the entry/exit counts for said functions, without much concern for a memory buffer overrun.

The Hacker’s Perspective: Zephyr OS and On-Device Runtime Protection - Natali Tshuva, Sternum IoT
Most embedded engineers rely on security patching and device hardening for their devices' security, and most people believe this is what should be done to ensure proper security for devices, but in fact, this is just not enough. In most cases, physical devices are left unprotected, exposed to security threats, and potential cyber-attacks. 
To understand the gap and what should be done we need to be able to see things from the attacker’s perspective.

This session will provide a unique view of the attacker's perspective on Zephyr’s based devices from former exploit/attack experts within the IDF Unit 8200. We will review the impossible task of identifying and mitigating all relevant vulnerabilities - and demonstrate the inadequacies in current IoT security practices focused on continuous patching, static analysis, encryption, and risk controls. We will also explain how attackers can easily evade such barriers, focusing on those that can make hardware security ineffective.

The session will also explore methods to achieve embedded, on-device runtime exploits protection to immunize devices from all underlying vulnerabilities, and provide zero-day protection for Zephyr-based devices.

Braiding Wires Into the Linux Network Stack - Recent Work on Embedded Networking - Oleksij Rempel, Pengutronix e.K.
Over the last few months, Oleksij has spent some time extending the Linux kernel's network infrastructure for embedded use cases - this includes, industrial, medical and automotive devices. As usual, any driver development starts from the basics and goes to advanced topics. The driver developer starts with the default hardware settings and makes them work. For example, with a Gigabit Ethernet controller, the first use case is a 1000BaseT full duplex link. While this works for most applications, some embedded use cases have special requirements. In this talk, we will look at the following topics: - Reducing power consumption - Addressing EEE support. - Weight reduction - using only one twisted pair (SPE) instead of four (1000BaseT1, 100BaseT1, 10BaseT1S, 10BaseT1L variants) - Reducing even more cables - Integrate Ethernet power into the mainline Linux kernel. Power over Data Line (PoDL) and Power over Ethernet (PoE). - Creating diagnostics - you can never have enough of them ;) In this talk Oleksij gives a brief overview of these and related technologies and their mainline state.

The main goal of the Linux4Space.org project is to create a reference Linux distribution as an open standard based on the requirements already defined by the stakeholders in the space industry. The primary use case of the Linux4Space is an operating system dedicated to running the payload in the background, working autonomously or semi-autonomously, with typically limited user interaction. We focus on implementing all the interfaces and device drivers required typically in the declared use case. We focus on delivering a safe and reliable version of Linux, capable of operating in highly demanding environments. We are happy to propose Linux4Space YOCTO layers structure and hopefully we are going forward to have the first version of our space Linux distribution. We are open to collaborating with anyone interested in any Linux space application.

(Live Virtual) Unlocking the Power of POSIX Support in Zephyr RTOS - Alexey Brodkin, Synopsys
Zephyr RTOS is a popular open-source real-time operating system used in embedded systems. It is known for its low-power consumption, small footprint, and support for various connectivity protocols. What many developers may not know is that Zephyr RTOS has had POSIX support since version 1.9, released back in 2017. This feature enables portability of software between different platforms and operating systems, allowing developers to run software written for other systems on top of the Zephyr RTOS with minimal efforts. In this presentation, we will showcase the advantages of using POSIX support in Zephyr, including reduced development time and cost, and increased compatibility with existing software. We will provide an overview of Zephyr's POSIX implementation, highlighting the supported APIs and limitations. Real-world use cases will be presented to demonstrate how POSIX support in Zephyr can unlock new possibilities in embedded systems development. We will also discuss the challenges and considerations when implementing and/or using POSIX in Zephyr RTOS.

ThingSet + Zephyr: Transport-Agnostic Device Connectivity Within 10 Minutes - Martin Jäger, Libre Solar Technologies GmbH
ThingSet is a zero-overhead remote API for embedded devices. It allows structured device data to be accessed using the same protocol for virtually any transport layer, be it a simple serial UART, Bluetooth, CAN bus, LoRaWAN, or IP-based protocols such as MQTT or WebSockets. Well thought-out naming conventions allow applications to discover necessary metadata from the device itself, including data types, units, or access rights. This talk will introduce the concepts behind ThingSet. It will also explore the open source library and the recently released SDK for Zephyr. The ThingSet SDK leverages some of the unique features of Zephyr, such as iterable sections, and provides out-of-the-box communication services as a Zephyr module that can be easily integrated into custom applications. Exposing meaningful data through various communication interfaces can be done with literally just a few lines of code. A live demo during the presentation will show how the firmware for a connected sensor can be implemented from scratch within 10 minutes. This includes interfacing with the sensor driver using the Zephyr API, defining the structure of the exposed data using ThingSet macros, setting up serial and Bluetooth communication interfaces, and testing everything with a mobile app.

Zephyr & Visual Studio Code: How to Develop Zephyr Apps with a Modern, Visual IDE - Jonathan Beri, Golioth
Visual Studio Code (or VS Code) has become a very popular developer environment for frontend and backend projects. But increasingly, embedded developers are turning to this tool too. “How do I get started with Visual Studio Code” is the most asked question in the Zephyr community Discord server. Out of the box VS Code isn’t setup up for embedded development but by leveraging extensions, supporting tools and the right configs, it can be a powerful IDE for you to use while building Zephyr apps. This talk we’ll cover the current state of Zephyr support in VS Code and I’ll share my VS Code setup and tips 'n tricks along the way.

Accelerated Mainline Linux Development Ahead of SoC Availability - Bryan Brattlof & Praneeth Bajjuri, Texas Instruments
All the work that goes into conceptualizing and designing all the multi-media and crypto accelerators, the GPUs, PRUs, DSPs, CPUs and everything else that goes into modern chips and the complexity this brings, we would be foolish not to test the design before spending the millions of dollars needed to produce a chip. Typically this means we will have Linux booting on these (simulated) devices long before these designs are ever etched into silicon. Join Bryan as he talks about how Texas Instruments uses the time they spend on pre-silicon development and testing to begin fixing bugs and adding support to the Linux kernel for all the chips TI produces each year long before silicon arrives at our desk.

Testing and Remote Access to Embedded System DPI/LVDS Display Output - Marek Vasut
Embedded systems often come with LCD panel for visualization. Making such system available in a board farm for remote access and CI testing is a challenging task often full of compromises. Testing each software update and verifying whether a panel is still running within precise panel vendor timing specification is even harder. This led to an idea to build a device, where the content sent to the panel is captured using an FPGA and passed to a PC for analysis, including pixel-by-pixel auxiliary signal state details. First part of the talk documents the journey toward this device, which became an FPGA video and signal capture PHY and USB UVC bridge, including development issues and failed attempts. The second part of the talk explains the design, the content of the FPGA, the USB FIFO controller, and the challenges of building PCB for such a high-frequency setup in hobby project conditions. Marek built this hardware at home, and so can you. Finally, a demo shows how this tool is used to measure the precise timing of PWM and synchronization signals of the panel to verify it is running within specification from panel vendor, and the image on display is exactly as it should be.

VZLUSAT-2: CubeSat with a Linux Payload Computer - Martin Sabol & Tomas Novotny, Czech Aerospace Research Centre (VZLÚ)
The VZLUSAT-2 nanosatellite, which started the second year of its mission in space, has the primary objective of taking images of the Earth's surface and collecting scientific data from gamma-ray and X-ray measurements. It demonstrates the possibilities of image data retrieval and processing using a Linux computer built on a COTS SoC. Using an embedded computer in low Earth orbit requires a specific approach, increased resistance to radiation, temperature fluctuations, and limited cooling capabilities. The main design advantages come from using Linux and exploiting its capabilities, i.e., automation of on-board processes and the possibility to extend functionality.

(Live Virtual) Zephyr Footprint – Where Are We and Where Are We Going - Ederson de Souza, Intel Corporation
Zephyr memory usage is of interest for those who want to use it in constrained hardware, limited to a few hundred kilobytes. In this talk, audience will be taken into what Zephyr currently does to keep its footprint down – such as compiler and linker options, as well as explore different approaches that can be used in the future; for example, a look into Zephyr current APIs (Application Programming Interfaces), based on function pointers, and how a "static dispatching" mechanism could help the linker to shave some dead code and reduce Zephyr's memory usage further.

Greybus for Robotics with Zephyr RTOS - Vaishnav Achath, Texas Instruments Inc.
Greybus is an application layer protocol developed originally for Google's modular smartphone project Ara and is a part of the Linux kernel, Greybus can be thought of as an Remote Procedure Call(RPC) framework which has tight integrations within linux kernel subsystems. In the past there has been multiple attempts for using Greybus for IoT applications where a remote node running generic greybus firmware will appear on the host running Linux as virtual devices and users can hook device drivers to these virtual devices. Thus reusing existing device drivers in Linux for remote microcontroller nodes running Zephyr greybus firmware(See https://git.beagleboard.org/beagleconnect/freedom for more info). This presentation discusses the method of using the greybus for robotics applications an real-time control applications where the traditional greybus frameworks transaction delays are not practical, thus a method of record and playback is added to the RPC framework on the Zephyr remote side which helps offload real-time control applications through greybus. The presentation also will include a demonstration of running a control loop on a remote microcontroller node running Zephyr and Linux host controlling through userspace drivers without modifying remote node firmware.

Using the Thrift RPC Framework in Zephyr - Chris Friedt, Meta
The Apache Thrift Remote Procedure Call (RPC) framework was a recent addition to the Zephyr ecosystem, gaining support with Zephyr v3.3. Originally developed at Facebook in 2007, Thrift is an IDL specification, RPC framework, and code generator. It works across all major operating systems, supports 28 programming languages, 7 protocols, and 6 low-level transports. Thrift supports a rich set of types and data structures, and abstracts away transport and protocol details, which lets developers focus on application logic. This talk will highlight: * Language Features with .thrift file examples * How Thrift reduces costs (through code generation, for example) * When it makes sense to consider Thrift * Incorporating Thrift into Continuous Integration Lastly, a brief interactive demonstration will be used to showcase just how frugal developing for the Zephyr RTOS with Thrift can be.

Keynote: Outsmarting IoT Defense: The Hacker's Perspective - Natali Tshuva, Co-founder & Chief Executive Officer, Sternum IoT
Endless patching is a race that cannot be won. To build sustainable, secure IoT solutions we must change that ineffective paradigm. To appreciate what we can do differently, we should start by considering both the defender's and attacker's perspectives. This session will provide a unique view of that attacker's perspective, from former exploit/attack experts within the IDF Unit 8200. We will review the impossible task of identifying and mitigating all vulnerabilities - and will demonstrate the inadequacies of current IoT security practices focused on continuous patching, static analysis, encryption, and risk controls. We will also explain how attackers can easily evade such barriers. By contrast, the session will explore methods for achieving embedded, on-device runtime exploits protection to immunize devices from all underlying vulnerabilities, and provide zero-day protection as well. These methods, commonplace in IT endpoint detection and response, are just now finding their way into heretofore unprotected and unmanaged IoT edge devices.

Evaluation of PREEMPT_RT in Virtualized Environments - Jan Altenberg, Open Source Automation Development Lab (OSADL) eG
As we all know, Industrial devices have very specific requirements. Most important is the need for deterministic timing behavior and, as a consequence, for a real-time operating system. PREEMPT_RT is the de-facto standard for real-time with Linux and has proven to be a good choice. Another technology that is gaining more importance in the industrial sector is virtualization. This trend originated from server systems and is now turning towards embedded devices. With several container technologies, virtualization solutions such as KVM, and Open Source-hypervisors like Jailhouse, the FOSS ecosystem has already more than one answer for it. Having these facts in mind, the questions arises if both technologies, PREEMPT_RT and the different methods for virtualization, can be used together. And, if so, is it possible to achieve real-time behavior not only of the host system but even of Linux systems running as guests? This presentation will give an overview of different virtualization technologies, namely Containers, KVM and the Jailhouse hypervisor. Based on long-term measurements, the real-time behavior within the host and the guest systems will be evaluated. In addition, it will be shown how the different technologies shall be configured to achieve the best possible results.

Setting up Yocto Layers and Builds with Official Tools – 2023 Edition - Alexander Kanavin, Linutronix
The Yocto project historically has not provided tools and standards for setting up and replicating layers and build configurations in a reproducible manner, leaving that to third party projects and custom scripts. In the past few months this has been changing, and many of the pieces are now available out of the box in oe-core/poky, or are under review. This talk will give an overview of what is available and how it can be used to both write a record of layer and build configuration, and to replicate that build elsewhere with that record. It will also cover parts that still need to be added, and possible future directions for layer and configuration management.

USB on Embedded Linux Systems Deep Dive - Marcel Ziswiler, Toradex AG
USB is one of the most dominant connection technologies. While it may be connected in a plug-and-play fashion just like on a regular PC, many modern Embedded Systems also contain directly designed-in USB components like USB-to-Ethernet chips. This talk introduces the USB specification and discusses how it may be used on Embedded Systems, from the USB recovery mode of modern SoCs, to boot loaders like U-Boot, the Linux kernel, and accompanying user space. It also introduces some available USB tooling useful in the Embedded space like USB-to-serial adapters/chips, USB (CAN, logic) analysers, or USB oscilloscopes. On the plug-and-play side, it covers role switching which may be realised either via extcon or connector subsystems. It continues up the stack to discuss various options like device/host functionality using different available USB class drivers and may involve such things as configfs or udev rules. The last part concentrates on how to debug various USB-related issues one may encounter. The powerful in-kernel usbmon facility is introduced which may be used to collect traces of I/O on the USB bus and in combination with wireshark allows easy visualising USB protocol analysis. As usual, I complete my talk with a live demonstration of some real-world USB use cases.

Arduino to RTOS - A Pilgrim's Progress - TJ VanToll & Zak Fields, Blues Inc.
The gulf between the tools we use to prototype and the tools we use to scale is broad. Or is it? Over the years, the embedded world has developed a narrative that there are two types of engineers: “makers” and “real world engineers.” Makers use Arduino and Raspberry Pi, develop using Arduino Wiring/C or Python. Real world engineers use eval boards from semiconductor companies and are never found without an RTOS. The problem is, this narrative isn’t true. Engineers of all types use Arduino, the Pi, and eval boards, depending on the need. And the choice of language is often more about the problem being solved and the goal of the application being written than an engineer’s experience or skill. And yet, for many of us, the venerable Real Time Operating System (RTOS) is still an area of perceived complexity. Perhaps due to the unwieldy-sounding “Operating System” part of the name, RTOSes are still looked upon as a tool only needed for “real” applications. But they don’t have to be. In this session, TJ VanToll and Zak Fields will share their journey from the Arduino world into ZephyrRTOS while building a case for developers to embrace Zephyr for all types of applications, and to make it a primary tool in their tool belt, available for all kinds of embedded applications.

Testing a Wireless IoT Product: Things We Wish Someone Told Us Before - Andreas Müller & Reto Schneider, Gardena (Husqvarna Group)
One important aspect of a comprehensive test strategy for an IoT product is automated testing using physical devices. Hardware-based testing comes with its own set of challenges, and this is particularly true for wireless devices. Luckily, many building blocks - great open source frameworks as well as various hardware tools - are readily available. In this presentation, Andreas and Reto share their experiences from testing a Zephyr-based implementation of a proprietary sub-GHz wireless protocol. They explain how to shield a testbed from unwanted RF interference and how to re-introduce interference deterministically, discuss a few adventures with USB, which hardware tools they found useful, and when even a really cheap tool may be sufficient in place of expensive test equipment. On the software side, the presentation discusses various useful features of Zephyr, the use of pytest for testing with physical devices, as well as some other valuable open source tools, such as GNU Radio and Scapy. While testing physical products in a noisy RF-environment can be a difficult challenge, this presentation shows how various tools and open source products help make the task a lot more accessible for everyone.

Camera Sensor Drivers Compliance - Jacopo Mondi, IdeasOnBoard Oy
Camera sensors are the building block on which system integrators and designers construct their product's vision and multimedia capabilities and differentiate their solutions based on the combined capabilities of the sensor and the on-board peripherals. Considering the sharp increase in the number of features a sensor can provide and the associated complexity of the required software support, the availability of open/free drivers as reference implementation is generally more and more relevant for the selection of what component to use in a design. While the Video4Linux2 framework already provides a compliance tool to verify the correctness of the interface to userspace application a driver implement, so far there has been no coverage for the validation and enforcement of the functional requirements a driver must implement. With the adoption of libcamera as the standard consumer for the Video4Linux2 kernel API, sensor drivers are now required to implement a common set of features whose implementation should comply with the expectations of user space applications. This presentation introduces to developers and system integrators the feature-set required by libcamera and how their implementation results in a more consistent code base for sensor drivers in the Linux kernel.

Fetching, Configuring and Building Your Bitbake Project with Just One Command - Jan Kiszka, Siemens AG
The open source project kas has its roots in the frustration about how tedious setup and hand-over of Yocto projects was. Started as a configurable Python script that combined git repository fetching with bitbake configuration file management, kas was quickly extended by a reference build container. With the rise of the Debian image build system Isar, it grew beyond its original domain and became the de facto standard for this new ecosystem. Still, most kas users and a growing number of contributors are coming from the Yocto/OpenEmbedded field. In this talk, we will introduce the philosophy behind kas and compare it to OE's new create-layers-setup feature and workflow. We will show how to bundle both configuration and build environment with your bitbake project using kas and kas-container and how to distribute this to other users or CI systems. Furthermore, we will look into advanced features like configuration file includes, interactive configuration menus, or secure integrity validation for repositories.

Adding Coredumps to Your Debugging Toolkit - Eric Johnson, Memfault
Investigating root causes of device faults is difficult, particularly for deployed devices. Typically local debugging and logging subsystems are used to determine issue causes. However, these tools have limited utility in many complex scenarios. Local debugging requires physical access, lacks a similar operating environment, and is invasive by modifying operation. Logging's unstructured nature makes efficient and effect analysis difficult. Coredumps capture detailed insight into device operation at the time of the fault in a non-invasive manner. Coredumps can be used defensively to catch existing issues. This talk introduces coredumps and how to use them in practice with Zephyr. Coredump data a valueable but often underutilized debugging resource. Coredumps contain highly structured data that can be easily parsed using GDB. Coredumps are flexible regarding what data can be captured. Let your imagination run wild! Got a memory slab that needs usage monitoring? Add it to your coredump! Sensor data that causes a unique stack overflow? Add it to your coredump! Topics covered include a brief overview of Zephyr’s coredump subsystem, how to configure the subsystem for different scenarios, how to use GDB with a coredump, and some examples of coredumps in practice.

Introducing CHESTER Platform for Industrial IoT Applications - Pavel Hübner, HARDWARIO
In this talk, Pavel will introduce the CHESTER platform, which helps developers to address many industrial IoT use cases requiring LPWAN (LTE-M, NB-IoT, LoRaWAN) or satellite connectivity. CHESTER scales to many applications because of its rich hardware extension module ecosystem and multiple Zephyr RTOS mechanisms, which help developers craft a truly modular software design. HARDWARIO (the CHESTER platform vendor) provides CHESTER SDK, which imports nRF Connect SDK (NCS) from Nordic Semiconductor. This layer has multiple reference application implementations, subsystems, drivers, samples, and shields. All those additions, altogether with the Zephyr RTOS and NCS foundations, give CHESTER users (even newcomers) the super-powers to develop and deploy industrial IoT applications in a fast manner. The talk may inspire any IoT firmware engineer about the often forgotten paradigms, such as modularity, re-usability, coherency, and cross-dependency avoidance.

rtla timerlat: Debugging Real-time Linux Scheduling Latency - Daniel Bristot de Oliveira, Red Hat
Debugging real-time Linux scheduling latency is a demanding task. And the demand for debugging this metric is increasing as more and more projects depend on it. For example, Linux in automotive and industrial applications is a trend. Furthermore, as the PREEMPT_RT merges, testing for scheduling latency regressions should be part of all developers' work.

Historically, the preempt rt is tested using black box applications, but this approach has several limitations, as it does not help to find the root cause for bad latency values nor help to establish a pattern between different cases.

rtla (real-time Linux analysis) is a kernel tool that facilitates debugging for real-time kernel features by integrating the measurements into kernel tracing features. In particular, rtla timerlat simplifies the debugging of scheduling latency by measuring the latency, tracing the main factors that cause a scheduling latency, producing a standardized auto analysis, and splitting the scheduling latency problem into small independent pieces of latency, all at once with user-friendly interface.

This talk will present the rtla timerlat tool, the details of the timerlat tracer, and the tool's auto-analysis output, as well as demonstrate a strategy for debugging complex scheduling latency problems.

Why Are GPUs (Not) Fast - A Trip Through the Driver Stack - Lucas Stach, Pengutronix
GPUs are often called accelerators and everybody tells us that they are supposed to make all things graphical go really fast. So why do they sometimes fall short of expectations and is there something we can do about it? This talk will first give a brief introduction to GPU hardware and how it differs from the traditional CPU. It will then work its way up through the different parts of the GPU driver stack until reaching the user visible APIs like EGL, OpenGL and Vulkan. The audience will gain a basic understanding on how the GPU hardware and drivers work and how to best utilize them both. Understanding the driver stack below the sometimes very abstract user APIs will help attendees of this talk to avoid performance pitfalls and utilize more of the acceleration potential when writing applications using the GPU. They will also gain a understanding how the graphics stack ties into the greater Linux ecosystem.

POSIX Roadmap for LTSv3 - Chris Friedt, Meta
Why support the POSIX API in Zephyr? We will begin with a brief history of POSIX API support in Zephyr, benefits to the ecosystem, initial contributions, and maintainership. We will explain the differentiation between CONFIG_POSIX_API and CONFIG_ARCH_POSIX and what roles each of those plays in the Zephyr ecosystem and why the two are currently at odds. The current state from the user perspective will follow. What POSIX APIs are supported? This will start from a 10,000 meter view and then zoom in on particular POSIX APIs, explaining why some POSIX APIs are supported and not others. How easy is it to port a POSIX library, samples apps, and testsuite to Zephyr? Believe it or not, it's relatively easy* and there are fairly exact steps to follow. The GSoC 2022 contribution of Apache Thrift will be presented as a case study. Finally, we will look at the LTSv3 roadmap, progress, and proposals, including * Publishing which POSIX embedded profiles are supported * Providing standard feature test macros * Better network API support * Coexistence with POSIX_ARCH * Support for automatic thread stacks * Moving POSIX headers from the toolchain into Zephyr

Subsystems with Object Lifetime Issues (in the Embedded Case) - Wolfram Sang, Sang Engineering / Renesas
At LinuxPlumbers 2022, Laurent Pinchart pointed out problems with object lifetimes in combination with managed device allocations. That means, devm_kzalloc() can lead to surprising Kernel crashes and corruptions. At FOSDEM2023, Bartosz Golaszewski investigated the topic further. He found out that the problems are worse, and even independent of managed devices. This talk now gives first an easy to grasp introduction to the problem. It then extends the previous talks by investigating what subsystems are actually affected and in which ways. The focus here is on subsystems used by embedded systems. At the end, potential solutions and likeliness to reach them will be discussed.

Tweaking Device Drivers for Achieving Real-Time Performance in Embedded Systems Using Real-Time Linux - Vaishnav Achath & Vignesh Raghavendra, Texas Instrument Inc.
The usage of Linux for Real-time embedded applications is increasingly becoming popular due to the versatility and flexibility provided by the HLOS along with the Real-time capabilities provided by Real-Time Linux. Multiple embedded use cases demand real-time microcontroller like performance from Real-Time Linux systems, even though Real-Time Linux core might be able to achieve similar performance for non-embedded use cases, the underlying device drivers and subsystems might not be designed for achieving similar performance requirements. This presentation discusses about analyzing the latency at each subsystem level, interaction between subsystems and generic driver level changes made to optimize for real-time performance without any hardware improvements, a case study of multi-core communication with Serial Peripheral Interface(SPI) will be discussed where the improvements made in SPI and DMA engine subsystem helped achieve MCU-like performance in a low cost solution without dedicated DMA for SPI, addition of flow control mechanisms to existing solution also will be discussed which helps achieve deterministic performance in real-time embedded systems even during high CPU loading. The optimizations discussed will be generic in nature and can be extended for different real-time embedded use cases.

Blinky 2.0: Graphics Acceleration on Zephyr RTOS - Daniel DeGrasse, NXP Semiconductors
As embedded processors become increasingly powerful, the demand for low-power graphics applications is increasing. Zephyr already offers support for driving a range of displays, from 128x64 dot matrix controllers to full color 1280x720 HD panels. However, many modern SOCs implement graphics accelerators, enabling these chips to drive rich graphics applications. Without support for these accelerators, Zephyr leaves performance and power savings on the table.  This presentation will discuss the current state of graphics in Zephyr RTOS and propose a new subsystem to enable applications to benefit from graphics accelerators present on the SOC. Given the variety of operations supported between various accelerators and the cost of CPU rendering in a graphics pipeline, this framework must be flexible and performant. Support for graphics acceleration in Zephyr will enable it to compete in segments demanding low power with modern graphics, such as the wearables market.
There will be a BoF after the presentation.

One of these cases is a Real Time Positioning System (RTLS), whose task is to precisely track 3D positions of some objects with a tracker attached. In this presentation, Aleksander presents a open source RTLS solution based on Zephyr RTOS and Decawave's (now Qorvo) MDEK1001 Ultra-wideband devkit. The presentation begins with the generic introduction into RTLS, followed by the description of the designed system. In the second part, Aleksander shares his experience on using Zephyr as a beginner and its unique features that have enabled him to rapidly implement the software for embedded devices. Finally, he'll speak about work that needs to be done to transform the solution into a generic Zephyr module, and how Zephyr facilitates the process of making code portable to numerous hardware platforms.

Simplifying Zephyr Usage Through Linux Host Integration - Jason Kridner, BeagleBoard.org Foundation
By creating a tight connection between Linux and Zephyr, introducing new IoT devices can be done quickly. Linux and Zephyr are both great databases of well-tested, community-reviewed sensor, actuator, indicator and connectivity drivers. Linux and Zephyr code bases are very different from the multitudes of available Arduino and Micropython code with vastly diverse quality levels and no driver model for standardizing usage within an application. This presentation explores 6 different mechanisms for connecting a new peripheral device to a Zephyr host and creating an associated data/control connection through a Linux host on a private network, namely: 1) Arduino code on Zephyr 2) Micropython on Zephyr 3) Linux userspace code over Greybus network-exported interfaces 4) Linux kernel driver usage over Greybus 5) Native Zephyr driver 6) Native Zephyr driver with Greybus-based sensor transport We'll explore the pros and cons of each to build awareness of the importance of native Zephyr and Linux drivers to open source IoT development. Support of Arudino and Micropython provides rapid-prototyping, but more critically, it introduces over-the-air updates and built-in networking stacks. The benefits of the Zephyr device driver model are explained from this perspective.

20 Years Teaching Embedded Linux: Lessons I Learned from My Students - Chris Simmonds, 2net
I gave my first Embedded Linux training course in 2002 when Linux was still considered a radical choice. Since then I have seen Linux become mainstream, to the point where it dominate in many categories of device. The hardware we use has changed dramatically, as have the tools to create the software.

One thing I discovered on my journey is that as a teacher you learn from your students: their ambitions, their concerns, and their feedback. In this talk, I want to give a little feedback in the other direction, and use that to review how things have changed over the last two decades, how some things have remained the same, and perhaps draw some conclusion about directions of technology and teaching in the future.

I hope this talk will be relevant to all embedded developers as well to those teaching others. I encourage every one to spend time thinking about how they can best keep the ball rolling, even in small ways, like helping your co workers, doing mini workshops and walkthroughs.

A Current Overview of the DRM KMS Driver-Side APIs - Paul Kocialkowski, Bootlin
DRM KMS has been around for over ten years now and is the de-facto standard API for display hardware support in Linux. It has replaced the legacy fbdev API that should eventually be removed from the kernel entirely. Yet DRM KMS is a complete (and complex) framework that has evolved quite a lot over time, bringing support for modern hardware and interfaces as well as important features such as atomic configuration, zero-copy buffer sharing, fences and many more. A downside of this is the relative complexity of writing new drivers, which can sometimes feel a bit discouraging to newcomers. This talk will highlight the main aspects of the current DRM KMS kernel-side APIs and how to use them for writing such drivers. It will cover various topics such as memory management, internal pipeline configuration, bridge and panel handling as well as complex interfaces handling (such as MIPI DSI and DP). Examples from actual drivers in the tree will be presented, as well as impressions from personal experience when writing the logicvc-drm driver and working on various panel and bridge drivers.

Adding Runtime Power Management Capabilities to Device Drivers - Shreeya Patel, Collabora
Runtime Power Management Framework was first introduced in 2009, and there are still many device drivers that incorrectly use the framework. Many developers have a hard time understanding it due to it's complexity and very technical documentation. In this talk, Shreeya Patel will focus on giving information about the RPM subsystem and it's callback functions, the reference counting process, power management through the SysFS interface, and some of the important helper functions using an example device driver i.e. the LTRF216A light sensor driver. The light sensor driver will also help everyone understand how adding RPM support can reduce power consumption for the devices by putting them into a low-power state when they are idle without any noticeable changes to the user.

(Live Virtual) Implementation of a Standard Interface for SMS in Zephyr - Jared Baumann, T-Mobile
Zephyr RTOS is a real time operating system that is quickly on the rise, with many companies adopting it in place of alternatives such as FreeRTOS due to many benefits Zephyr provides. One of the largest benefits of Zephyr is the standardized interfaces it provides for many devices and protocols. As such, expanding upon these can provide great benefit. Working with T-Mobile, Jared sees utility for the Zephyr RTOS within cellular IoT applications, and as such seeks to improve functionality of cellular modems through better support of their various functions. In particular, his presentation will cover an initial concept for a standardized interface for SMS messaging for use within Zephyr.

Connecting and Managing Zephyr Devices Remotely Using LWM2M and Eclipse Leshan - Julien Vermillard, EdgeIQ
The number of Zephyr-based connected devices is rising fast, but how can these run safely and efficiently using standards? OMA Lightweight M2M is an IoT protocol for managing intelligent objects. It addresses specific IoT needs: monitoring, configuring, securing, and upgrading devices. It is bandwidth efficient and fits constrained embedded environments while providing friendly and discoverable RESTful API. Zephyr’s built-in LWM2M client can easily be coupled with Eclipse Leshan [1]—a Java library that helps write LWM2M cloud servers and manage them at scale— to build an end-to-end, secure, IoT device management infrastructure. After introducing the LWM2M standards, we will show you how to use the Zephyr LWM2M client with Eclipse Leshan to expose your device capabilities and create a server for managing a fleet of devices and collecting sensor data. We’ll conclude with some insight into what is cooking inside the Leshan project and some examples of it being used commercially within the IoT platform industry. [1] https://www.eclipse.org/leshan/

Introduce Hardware-Level Device Isolation to Zephyr - Jaxson Han & Huifeng Zhang, Arm
Most architectures in Zephyr use MMU/MPU to isolate the thread memory regions so that the system is protected from buggy or malicious code. However, MMU/MPU can only limit memory accesses from CPUs. Memory accesses such as those from DMA are not protected by MMU/MPU, which may cause critical security issues. This issue should be brought to attention because Zephyr has been adding more DMA devices to the code, while many DMA devices might be buggy or even malicious. Therefore, without taking actions, Zephyr would be under increasing security risk. RichOSes use IOMMU/SMMU to protect the device memory accesses in general, and likewise, Zephyr can mitigate the above-mentioned security issue by introducing the IOMMU/SMMU technology. Additionally, the introduction of IOMMU/SMMU makes Zephyr possible to support more PCI and DMA devices or even features such as virtualization. Because of the variety of hardware-level solutions provided by different architectures, it is necessary to add a new IOMMU/SMMU Subsys framework for Zephyr so it can be easily extended in the future. This talk will cover the Zephyr Arm SMMUv3 support based on the Subsys framework. A live demo will be presented to showcase using SMMUv3 to protect memory access from a PCI AHCI device on the Arm FVP platform.

Tim will lead this panel in discussing the current trends in the usage of Linux in space missions. Linux has been used in satellites and rockets for almost 20 years now. But the Linux4Space initiative only started last year. It is estimated that over 50% of cubesats now run Linux. At the same time, Planet and SpaceX have constellations of satellites that are running thousands of instances of Linux in low earth orbit. Tim will discuss Linux usage in space missions with a few experts from academia and the industry, to find out their thoughts on where Linux is being used effectively (or not), and what we can expect for the future of Linux in Space.

A Bridle for Your Kite - Best Practices for Downstream Development with Zephyr - Stephan Linz, Navimatix GmbH & Tobias Kästner, UL Method Park GmbH
With west and the CMake build system Zephyr already offers a lot to address many of the challenges of embedded software development. Rooted in the Open/Closed principle, many of these tools and subsystems can be extended to increase productivity. The Bridle open source project aims to serve as a comprehensive blueprint for the development of embedded software. Teams can use it as a scaffold to implement product specific applications, subsystems and test suites as well as hardware descriptions and documentation. Making use of the available extension points Bridle implements strategies to efficiently migrate to newer upstream versions, prepare contributions for upstream while making sure that those parts meant to be kept private remain so during the entire product lifecycle. Using examples from the Bridle project the talk will explain how to add useful west commands for downstream tasks and how to extend to tailor document generation for downstream needs. The talk will also show how to extend Zephyr's CMake system with downstream modules and how even a project specific package can be created. In the talk's last section the presented possibilities will be compared to typical project requirements encountered in regulated environments such as the medical industry.

Building Embedded Systems with AOSP - Why You Should Consider, Best Practices and Pitfalls - Anna-Lena Marx, inovex GmbH
In our community, building embedded systems based on Linux, e.g. with Yocto or buildroot, is standard and well known. Considering Android, respectively the AOSP as a base system feels strange at the beginning as it is a huge ecosystem that implies high system requirements. Of course, embedded Android is not a solution for each issue. Nevertheless, the AOSP provides a sophisticated base platform which is packed with a - modern UI stack - robust media and camera implementation - modern AI runtime - well known abstraction between system and app development - energy optimization and lots of other helpful infrastructure. This makes AOSP an interesting approach for building more complex embedded systems. A first goal of this talk is to show in which situations choosing AOSP over a plain Linux system really adds value and where not. But where to start and how are the best workflows? The AOSP is a massive and complex code base with a few hundred GB of source code. Navigating the sources, finding the right place to do changes and working with several code repositories at once is a tough task at the beginning. Thus, the second goal of this talk is to share best practices and hints to avoid lots of pitfalls from 8 years of doing embedded Android projects in different setups and sizes.

Kernel CI – How Far Can It Go? - Nikolai Kondrashov, Red Hat
Over the years, we've seen multiple kernel-testing systems emerge, which make results available to maintainers and developers: 0day, Syzbot, KernelCI, LKFT, CKI, and so on. However, their impact remains uneven, and limited: only some subsystems have test requirements for contributions, an even smaller number have pre-merge CI, and testing of the rest is opportunity-based.
Maintainers and developers are generally cautious of automated test results: they often reproduce issues unrelated to the change in question, and fail due to framework, infrastructure, and test code problems. This is a chicken-and-egg problem: unreliable test results can't be used for gating, but they are not improving much until they are. The current feedback loop is just too weak and slow. Let's discuss possible ways to improve this, and how far we can possibly go.
The KCIDB project, being developed by Linux Foundation's KernelCI, is aggregating and sharing data coming from various Kernel testing systems and building unified dashboards and a notification system for maintainers and developers. Eight systems of various sizes are contributing already, with more working on joining. We are going to share some ideas we're working on together with testing systems for improving the testing side of the equation.

SEAPATH: Configuring and Testing an Industrial-Grade Linux Platform for Critical Real-Time Applications in the Energy Sector - Aurélien Watare, RTE & Eloi Bail, Savoir-Faire Linux
The energy sector is following the telecommunications field by moving towards virtualization for increased flexibility and cost reduction. This leads to an IT/OT convergence where critical applications, previously hosted on specific hardware, become virtual machines. However, these applications require high availability, real-time performance, and cybersecurity. SEAPATH is a project under the LF Energy umbrella that provides a solution for building a real-time virtualization industrial-grade platform based on Yocto or Debian. The technology behind SEAPATH includes the use of Ceph storage, Linux RT, Pacemaker for high availability, Open vSwitch (OVS) for network virtualization, SR-IOV for hardware acceleration, KVM for virtualization, and PTP synchronization for accurate timekeeping. This presentation focuses on the infrastructure-as-code dimension using Ansible, and also describes the continuous integration (CI) process that enables the running of tests on dedicated hardware to validate cybersecurity, deployment, performance, and other key factors.

Coding Guidelines – to Comply or Not Comply – Some Myth Busting - Nicole Pappler, AlektoMetis & Philipp Ahmann, Robert Bosch GmbH
While adhering to certain coding styles is a good practice in software projects, adhering to coding guidelines for safety critical applications is still something rather exotic in open source projects. As open source projects now more and more start to address the needs of functional safety applications, considering coding guidelines preferred by existing functional safety projects seems to become necessary. The most used rules for coding guidelines in the safety critical context are MISRA rules. While applying these can be quite beneficial for most applications, there is a significant number of exceptions where blindly following these rules causes more problems than it solves. With this talk the authors discuss the most common coding guidelines, best practices and arguments when following the MISRA rules conflicts with the expectations of the project. Acceptance criteria for non-compliance cases along with examples of acceptable deviations will be presented. This talk is not contra coding guidelines, but illustrates how coding guidelines are beneficial for a project, what to consider when designing a project’s coding guidelines and how the lessons learned by the application of MISRA rule sets can be applied to languages that are not (yet?) covered by widely accepted rule sets.

A Developer's Diary: The Trials and Triumphs of Maintaining Devboards in AOSP - Amit Pundir, Linaro
One of the most important aspect of supporting a device in a big project like AOSP, is to keep up with the always churning changes, be it the AOSP or the target Linux kernel version or any external project (eg Mesa), depending on the level of features being supported on that device. In this session we will look into the realities of AOSP devboard development and maintenance from a developer's perspective. As an Android ecosystem influencer, Linaro plays an important role of keeping its share of devboards up-to-date in AOSP. The usage of AOSP devboards is not just limited to testing latest and greatest version of upstream projects. They have also been used as proof-of-concept or prototype devices to develop or work on new AOSP features like Android GKI, DMA BUF heaps to name a few. But maintaining them in AOSP is a pain, just like any other Linux distro. In this session, Amit will share his struggles and stories of: * Subtle AOSP and upstream breakages, * AOSP bring up on newer SoCs with minimal (headless) config, * Booting AOSP with software rendering support, * Updating AOSP external projects to keep them in sync with their upstream development or release branches, * Chasing never ending boot image header version mandates from AOSP et al.

Automated Testing and Continuous Integration/Delivery: Lessons Learned - Marcel Ziswiler, Toradex AG
Three years ago we set out to build a modern automated testing and continuous integration/delivery (CI/CD) pipeline with the goal to deliver more and better-tested software. Given our open source focus our entire source code was already managed in GitLab which is a great advancement from regular Git adding features like CI/CD. We put GitLab CI in place to check and build any major BSP source code we touch. Another building block is our Jenkins infrastructure able to do complete nightly builds of our entire Embedded Linux stacks (Yocto Project based). Artifactory manages the build artefacts with full over-the-air update integration. To allow testing on real hardware we set up LAVA infrastructure which manages an entire board farm of currently 47 devices and allows automatic regression testing of complete Embedded Linux images on real hardware. For this purpose, we built entire shelves of up to seven carrier boards each holding various different SoMs. Various interfaces either connect to real-life devices like SD cards and USB memory sticks or are looped back for testing. This talk introduces all the components and concepts both on the hardware as well as software side, the orchestration thereof, and discusses various things we learned on our journey to successful CI/CD.

Efficient and Practical Capturing of Crash Data on Embedded Systems - John Ogness, Linutronix GmbH
The core dump facility of Linux can be a powerful tool for developers to investigate why their application crashed. When active, it can store a snapshot of an application's memory at the time of a crash. This allows for detailed inspection of stack traces and data contents. However, this facility is rarely used on production systems because of the space required to save the core dump files. This is particularly true for embedded systems, where read-write space is often very limited or non-existent. The minicoredumper project [0] was created to make core dumps viable for even embedded systems. It does this by providing a set of userspace tools to extend the Linux core dump facility and allow fine-grained control over what exactly is saved when an application crashes. Using the minicoredumper, very useful core dumps for applications can be reduced to 4KB of space, making them very attractive even for embedded systems. This presentation introduces the minicoredumper project, explores some of the details as to how it works, and provides some scenarios showing how it can be used in embedded systems.

Kernel Locking Engineering - Daniel Vetter, Intel
Engineering a kernel locking design for a new driver or subsystem is hard, especially when it should be maintainable, easy to evolve and also correct. This talk will present a few principles, common pitfalls and then develop a hierarchy of locking and data protection and access schemes for concurrent code in the linux kernel, starting from the simplest to understand and easiest to maintain, to the trickiest and hardest to implement correctly. The focus is on a set of patterns and recipe style approach to help make the right design decisions in both common and rare cases. These locking engineering patterns have been extracted from over a decade of driver subsystem maintainer experience extracting the good from the bad designs, so that you don't have to repeat the same old mistakes.

The AOSP Build System - Chris Simmonds, 2net
AOSP has multiple build systems: Soong, Kati, Make and Bazel. Unfortunately you need to know all of them if you want to develop AOSP modules and debug build errors. In this 90 minute workshop I will take time to show the parts that each has to play in creating Android device images and other artefacts. I will begin with the overall architecture, from parsing recipes to writing the Ninja manifests, through to executing the tasks. I will look at log files to show how thing progress and the kind of things that can go wrong. Next, I will look at Soong and the Soong recipe language, Blueprint. I will show how to write Android.bp files for various tasks. Then comes the legacy Makefiles and the Makefile parser, Kati. The intention was to replace Makefiles with Blueprint (or so I believe) but after 6 release, Makefiles are still here, especially in the low level definition of a device. I will show you the important parts Finally, I will address the new kid on the block: Bazel. Currently used to build the kernel, we are given to understand that Bazel will eventually take over There will be live demos!

The End of the Paved Road: Maintaining Linux Kernel 4.4 Beyond LTS - Ulrich Hecht
They said it's pointless. They said it can't be done. Here's how the Civil Infrastructure Platform is doing it. And why. In its mission to provide a software base for industrial and civil infrastructure projects, the Linux Foundation's Civil Infrastructure Platform project (CIP) is committed to maintaining their Super Long Term Support (SLTS) kernels in both their regular and real-time versions for a minimum of ten years from the time of release. When a kernel is brand-new that is a rather straightforward task. For several years much of the work is done by the Linux stable kernel maintainers as they provide maintenance for Long Term Support (LTS) kernels. But there inevitably comes a time for any kernel version at which it is discontinued. That is the time the CIP kernel maintainers have to get out of the back seat and take the wheel, because giving up is not an option. That time is now. The retirement of LTS kernel 4.4 marks the first time in the CIP project's existence that their kernel maintainers have to go it alone. Ulrich Hecht, current maintainer of the SLTS 4.4 kernel, will tell you how the CIP project intends to keep 4.4 (and its future SLTS kernels) alive for as long as it takes.

Open-Source Interoperability Toolkit for Integration of Distributed Energy Storage and Other Flexibility Resources: Project InterSTORE - David Trafela, Sunesis & Nikolaj Candellari, CyberGrid
The overall vision of InterSTORE project is to deploy and demonstrate a set of Open-Source Interoperability Toolkit to integrate Distributed Energy Storage and other Distributed Energy Resources, to enable the hybridization, utilization and monetization of power flexibility. Seven high impact use cases will be demonstrated in four pilots.

The goal of developing interoperability and seamless data sharing is very ambitious and lies at the technical and methodological advances: (a) protocol based on the IEEE 2030.5 standard (b) use of NATS connective technology that powers modern distributed systems (c) implementation of connected data spaces.

To ensure the development and maintenance will continue after the end of the project an active community will be established, hopefully with the support of international organizations such as Linux Foundation Energy. A special effort will be placed on making sure that the work done within this project will be considered by on-going standardization activities. Partners will release Open-Source Interoperability Toolkit with GNU Lesser General Public License (LGPL) 3 open-source license to help the software to become a standard reference protocol.

wolfBoot: Open Source Secure Boot and Remote Firmware Updates in Safety-critical Embedded Systems - Daniele Lacamera, wolfSSL Inc.
Secure boot has become a key requirement for modern embedded systems that rely on frequent and reliable firmware updates. The bootloader is a critical component playing a key role in the process of verification of the authenticity and integrity of the firmware installed on the device, and the subsequent updates.

wolfBoot is an Open Source, highly portable, secure bootloader that has been developed on the basis of RFC 9019 recommendations, with a specific focus to reducing the attack surface and mitigating several types of well-known attacks, including glitches and fault injections. Initially designed for ARM Cortex-M microcontrollers, it has been successfully ported to many architectures, including RISC-V, ARM Cortex-A, PowerPC, x86 and even Intel TigerLake, as a safety-oriented replacement for SlimBoot.

wolfBoot relies on wolfCrypt for the implementation of cryptography algoritms. The crypto components included in wolfCrypt have been successfully certified for use in DO-178C systems, up to DAL-A.

Moreover, wolfBoot design imposes predictible execution flows, no interrupts in the bootloader stage, no dynamic memory allocation and a very low line count. These characteristics are in general a very good match for the requirements for embedded systems in safety critical domains.

Cross-platform UI Engines Rendering Performance - Andy Wingo, Igalia
Why would Signal have chosen to make completely separate apps for Android and iOS?  Is there any hope for making high-performance mobile apps in an open source, cross-platform way?
In this talk, we first take a step back and try to characterize the state of the field: how is it that people make good-performing, pleasing apps these days for Android, for iOS, and in a cross-platform way?  Having extracted some lessons from the state of the art, we apply them to identify opportunities and to predict the future.
Coming at the topic from a compilers perspective, this talk focuses on the mechanisms at work in modern app development frameworks: the platform-specific SwiftUI and Jetpack Compose but also the cross-platform React Native, Flutter, and other JavaScript-based cross-platform frameworks.  We identify a number of commonalities but also note that the field is in a phase of recomposition, coming out of the world where the only answer was "write it once in Java and then again in Objective C".
Topics discussed: ahead-of-time and just-in-time compilation, declarative programming models, the relationship between language design and performance, WebAssembly, JavaScript, TypeScript, Kotlin, Swift, Rust, garbage collection, concurrency, standardization, the web, among many others.

Designing to the Worst Case Scenario - Practical System Call Filtering with Seccomp - Simon Goda, Doulos Ltd
In this talk we look at how we can protect our embedded Linux systems by running potentially vulnerable applications (e.g. those that require user input or open files) with system call filtering in place. The kernel’s Seccomp feature and the corresponding user space LibSeccomp library can be used to limit and control the system calls a process can make. If the application is compromised in some way and attempts to do something undesirable it can be stopped in its tracks! We will look at how to do this directly by launching application as a child process. We’ll also see how these filters can be put in place at a system level using SystemD or in an isolated execution environment using (for example) LXC containers. This talk extends an earlier short presentation “Confining Linux Applications with LibSeccomp” which was presented at the IoT Security Foundation 8th Annual Conference in October 2022.

Learn How to Support Your SoC and ISP in Libcamera - Laurent Pinchart, Ideas on Board
libcamera is the only open-source camera framework for Linux systems that supports ISP-based cameras. Thanks to its integration with other key multimedia frameworks such as GStreamer or PipeWire, libcamera's adoption is increasing across all market segments, from embedded devices to desktops. More and more ISP and SoC vendors are exploring how to add support for their platforms to the project. Yet, while libcamera's goals, design, architecture and application API have been presented in multiple conferences over the last years, little has been said of how to support a new platform. This talk will dive in the libcamera's internals, and explain, with real life examples, how to support a new platform. The audience will learn how to implement a pipeline handler, write image processing algorithms to control the ISP, and use the compliance test suite to validate the result.

RT Linux in Safety-Critical Systems: The Potential and the Challenges - Elana Copperman, Mobileye & Shuah Khan, The Linux Foundation
The Real Time Linux (RTL) collaborative project was established to help coordinate the efforts around mainlining Preempt RT and ensuring that the maintainers have the ability to continue development work, long-term support and future research of RT. The RTL project has been active in adding Preempt RT features in to the mainline kernel. It is time for a closer look on how these features can be used in Safety-Critical Systems. In this talk, we provide a brief overview of Real Time Linux and potential usage in Safety-Critical systems. In addition, we will discuss how these features may be relevant to support system safety. We will go over the following areas that are most relevant: 1. Tools for analysis of system workload resource usage and performance impact. 2. Kernel configs, guidelines on usage. 3. Relevant system parameters, generic and architecture specific. 4. Test frameworks and how they may be used to investigate and demonstrate safety features.

Do the Time Warp – the Rocky Horror PTP Show: Verification of Network Time Synchronization in the Real World - Johannes Zink, Pengutronix e.K.
Many realtime network applications require tight time synchronizations between the different nodes in a network. The Precision Time Protocol PTP can provide clock synchronization down to the nanosecond range. In order to achieve such tight synchronization, hardware timestamping of PTP packets is used, for which the Linux kernel provides the kernel PTP hardwareclock infrastructure, while linuxptp implements the PTP protocol stack in userspace. Proper configuration of the components involved and the setup of the PTP daemons and hardware can be a difficult task, because even minor configuration issues have a huge impact on the overall performance. After a short introduction into PTP and synchronization of PTP hardware clocks, this talk introduces different methods for measuring clock synchronization and compares their advantages and disadvantages. Using examples from real world projects, this talk will show common pitfalls when starting to set up new PTP projects and how to avoid them. Last but not least, this talk will show misleading software debug outputs, time jumping back and forth, and many more fun effects you can encounter when setting up PTP in your network for the first time and how to debug these issues.

Threads in Embedded Linux- 6 Easy Pieces - Loïc Domaigné, Doulos
Processes, Light-weight processes, (green) threads, fibers, co-routines, tasks, you named it. All these names refer to programming models for implementing concurrent processing efficiently. In this talk, Loïc is going to provide you a map of how to navigate the threads landscape on Linux. The talk starts with a brief review of the clone(2) system call, and how this translates to processes and threads at user-space level. It then reviews the thread life cycle (creation, joining, detaching, exiting), followed by a focus on the thread stack and size and illustrates how glibc and musl differ in that regard. Loïc then discusses memory synchronization, mutexes and condition variables and shows typical use. The talk concludes by looking at threads and signal delivery. This is a practical hands-on talk, so we'll demo (broken-) code, look under the hood what's going on using tools like pmap, strace, ltrace,.. and possibly will have a peek at some musl or glibc code implementation! Featuring: Help, compiling with "-pthread" breaks my non-threaded code! When threads strike and refuse starting. Did you say stack size? Aren't mutex just binary semaphore? What's the condition in condition variable? There was once a happy bunch of threads in a process, suddenly a signal is delivered…

Using Linux as an Embedded OS for the Space Industry - Pierre Ficheux, Smile
Most of the time, the space industry uses dedicated OS (such as RTEMS, LithOS or PikeOS) for which a qualification process following ECSS rules has been performed or even “bare metal” software for the missions.  Nevertheless, Linux has been used for some missions such as the SpaceX Falcon9 which uses a redundant system based on several x86 Linux computers.  In 2020, the CNES and some major European players of the space industry started a study in order to define and build a Linux distribution that would meet a wide range of needs encountered in space missions (spacecrafts and payloads).  The first version of the distribution was delivered in June 2022 and the evolution is expected to be handled by an open source community sharing experiment, software components, documentation or tutorials. During the conference we will start with a state of the art of the use of Linux in space missions, then we will focus on the main steps studied during the project. Taking in account the needs of the space industry  - Security, safety and certification - Footprint - Space standards support such as SpaceWire - Partitioning (using an hypervisor) - Setting up and managing the community source repository (binary images, tutorials, etc.)

A Tour of USB Device Controller (UDC) in Linux - Hervé Codina, Bootlin
This talk is a presentation of the USB Device Controller (UDC) subsystem in Linux. It will focus on USB 2.0 devices but the topics presented will also be relevant for USB3. A USB Device Controller (UDC) is one component of a USB Gadget. A USB gadget is made of one or more USB functions exposed through one UDC. The USB functions are in charge of the functionalities and the UDC handles the transfers on the USB Endpoints involved in the USB gadget and drives the hardware to perform such transfers. In this talk, we will first give an introduction to the USB 2.0 standard. We will highlight the different types of transfers, the available standard control requests and the standard device states. Then, based on the USB 2.0 standard introduction, we will describe the goal of the UDCs and how they are implemented in the Linux kernel with a particular focus on the USB EP0 control handling involved in the USB enumeration process. The last part will present a tool available and several pre-composed USB gadgets that can be used to test a UDC.

How Much Is Tracing? Measuring the Overhead Caused by the Tracing Infrastructure - Andreas Klinger, IT-Klinger
When using tracing facilities like ftrace in realtime systems it's uncertain how well one can rely on the absolute timing values delivered in the output. By measuring we are also always affecting the measuring object. Andreas investigated the effects of tracing on the target system. He created a kernel driver which is toggling a gpio output all the time in a tight loop and monitored it with the oscilloscope. By applying kernels with different configuration on this measurement setup one can easily see the difference and thus calculate the overhead. Measured kernel configurations include some different tracing configurations, with and without kernel preemption as well as the realtime preemption patch. On the tracing techniques side he examined tracing events, kernel probes, user probes, trace markers and eBPF events.

ELISA Status and Outlook: Advancing Open Source Safety-Critical Systems - Philipp Ahmann, Robert Bosch GmbH
These days, open source software can be found in almost every reasonably complex product running software. It runs in medical devices, robots, vehicles, and even outer space. In the underlying industry sectors, certification and safety integrity standards play an important role which at first glance seem at odds with the use of pre-existing open source software, not developed strictly in accordance with industry standards. In this talk recent ELISA project deliverables in the field of elements, processes, and tools are highlighted. These include system theoretic process analysis, workload tracing, call-tree visualization on kernel level, and reproducible example use-cases from the field of medical devices and automotive. Their role in reducing the burden for companies to build and certify open source based safety-critical applications is shown. Additionally, an overview of upcoming ELISA activities in 2023 is provide and how cross project collaboration is established, as the ELISA work streams include interaction with e.g. the Zephyr, Xen, AGL, yocto, and SPDX community. A few statements on the overall challenges of safety-critical use cases using free open-source software will help to pick up those audience which is new to safety-critical or open-source software development.

Linux Power! (from the Perspective of a PMIC Vendor) - Matti Vaittinen, ROHM Semiconductor
Powering-up a modern SOC can require a few different stable power sources. Also, a run-time control for voltages is often required to enable optimal power usage and power-savings – or to mitigate heating issues. In many cases some more advanced features like RTC, Watchdog or battery-chargers are tightly coupled with power input. This talk aims to give a generic overview on what a Power Management Integrated Circuit (a PMIC) is and what kind of drivers may be required. From this very generic overview the talk will dive deep into providing functional-safety related notifiers via the Linux regulator framework. The talk attempts to shed some light on how to inform abnormal conditions like over-/under [voltage, current, temperature] via the notifiers – while asking from the audience about any experience on using these notifiers.

The Xenomai Project : Current and Future - Pierre Ficheux, Smile
Using Linux for RT applications is always an issue. PREEMPT_RT is the official way for Linux RT. It is quite simple to configure (and to use) because it’s based on the mainline kernel. It’s mostly architecture independent and uses the same API as the standard kernel. Xenomai is based on another technology. Instead of patching the Linux kernel to improve real-time scheduling, Xenomai uses a real-time co-kernel running as a Linux kernel module. Most of the time, it leads to (much) better performances because the co-kernel approach (initially based on I-pipe) is more efficient than a PREEMPT_RT kernel. Xenomai is currently maintained by a group of enthusiasts including Jan Kiszka and Philippe Gerum. The current developments focus on Dovetail which is an I-pipe replacement for recent kernels. The current version of Xenomai uses Dovetail or I-pipe dependending on the kernel version. During the conference, we will describe the Xenomai architecture and how to build and use it. Then we will talk about the migration from the I-pipe approach to Dovetail. Finally we will introduce the EVL project which is a new real-time core and the base of the future Xenomai 4. The conference includes a comparison of the performances between Xenomai and PREEMPT_RT (demo)

Tracking Vulnerabilities with Buildroot and Yocto - Arnout Vandecappelle, Mind
When an embedded product is released, it is certain to contain vulnerabilities that can allow threat actors to abuse the device. A responsible provider proactively tracks and fixes these vulnerabilities before they are abused. Vulnerability databases, like CVE, publish them, but it would take an unrealistic amount of time to track every entry in the CVE database. Fortunately, embedded build systems provide some tools that make tracking of vulnerabilities easier. Arnout has used both Buildroot and OpenEmbedded (yocto) to develop products. This talk explains the various tools that either of them provide to track vulnerabilities, and what this means from a practical perspective as a product developer. Shortcomings in the flow are highlighted, with ideas of how the build systems and other tools can be improved to make life easier for the embedded developer.

Camera Applications with Libcamera and PipeWire - Daniel Scally, Ideas on Board Oy
libcamera support is growing rapidly. With support from PipeWire, desktop integrations and convergent applications can run on laptops and mobile alike. WebRTC has gained support for using the PipeWire Camera Portal, allowing browsers and conference applications to talk to PipeWire, to manage a complex camera through libcamera. But video is not the only use case for cameras through libcamera. Platform agnostic camera photography applications are being developed and supported including Gnome-Camera, and Harbour-Pinhole which can run on a Desktop PC, small board computers, or supported mobile phones running PostmarketOS or a custom Linux distribution. This talk continues from the previous talk "Application Support with libcamera" given at ELCE-2022, and will explore the progress being made with browser integration for the camera portal and how that will bring conference calling features expected by Linux users with complex cameras back into the 21st century, and further look at how libcamera can be used for photography use cases with mobile devices using standard applications. Demos will be made with the latest implementations.
