Sponsored Session: Your Dev Environment Is Probably Slowing You Down - Ben Potter, Coder

Wednesday October 7, 2026 14:25 - 15:05 CEST

South Hall 2 A (Floor 2)

Every developer has felt it: a fresh clone that takes hours to get running, a build that only works on one machine, or a setup that's impossible for a teammate - or an AI agent - to reproduce.

As projects grow, developer environments become infrastructure in their own right. Get them wrong, and onboarding slows, builds become fragile, and "works on my machine" never really goes away.

This talk explores the patterns behind development environments that scale - from solo open source projects to large mono and multirepos. We'll look at reproducible environment definitions, dependency caching, ephemeral versus persistent environments, and where tooling should replace documentation.

You'll also learn how high-performing teams measure developer experience with metrics like time-to-first-commit and onboarding time, rather than intuition, and why the best developer platforms succeed by making the right path the easiest one.

AI agents are now consumers of your development environment too. If a new contributor can't get started quickly, neither can an agent.

Whether you maintain an open source project or build software at enterprise scale, you'll leave with practical ideas for creating faster, more reproducible development workflows that developers actually want to use.

Sponsored Session: Kubernetes Is the AI OS. Here's the Open Source Stack Running on Top of It - Jonathan Bryce, The Linux Foundation & Daniel Krook, CNCF

Wednesday October 7, 2026 15:35 - 16:15 CEST

South Hall 2 A (Floor 2)

Kubernetes has become the AI operating system (82% of container users run it in production and 66% use it for AI inference) but the real challenge is scaling inference, not training. Every prompt and every agent call runs inference, and standard Kubernetes routing is blind to the KV cache state and token dynamics that determine whether you hit your SLOs. This session covers the open stack the CNCF community is coalescing around to fix that: HAMi (now Incubating) for fractional GPU virtualization and hard accelerator isolation, Inference Gateway (GA) for model-aware traffic routing, llm-d (new CNCF Sandbox project) for cache and load-aware distributed inference, KServe (Incubating) for multi-model serving, and the KAR (Kubernetes AI Conformance Requirements) program now spanning 31 certified platforms. We’ll also cover four trends shaping the next 12 months of cloud native AI.

Your Network Is Already a Compute Platform. Time To Treat It Like One - Eleni Grosdouli & Josh Halley, Cisco

Wednesday October 7, 2026 17:25 - 18:05 CEST

South Hall 2 A (Floor 2)

Network switches and routers are no longer passive packet forwarders. They have been running containers for some time already. But managing them still requires separate tools, CLIs, and workflows, and that creates real operational friction.

Virtual Kubelet eliminates this. Network devices become Kubernetes nodes. Workloads are provisioned with standard kubectl commands. Device configuration is declared as Kubernetes resources with continuous drift detection. Telemetry flows through OpenTelemetry to any OTLP-compatible backend.

This session demonstrates how to converge network and platform operations into a single control plane. We will demonstrate live provisioning of network devices and show how the CNCF ecosystem enables observability, security, and policy enforcement for edge deployments.

Demystifying Functional Safety in Zephyr RTOS - Alexandre Bailon, BayLibre

Thursday October 8, 2026 09:05 - 09:45 CEST

South Hall 2 A (Floor 2)

There is an increasing demand for functional safety and certifying Zephyr RTOS from SoC vendors and companies wishing to make medical and automotive products. In the meantime, there is a lot of pushback from developers who believe that open source software is not compatible with the rigors and the processes required by functional safety.
Alexandre Bailon is an active Zephyr developer who had no knowledge about functional safety. After attending numerous talks, he found himself facing more questions than answers.
Alexandre Bailon will give the talk he would have expected as an open source developer. He will first explain what functional safety is and why this is a must-have for Zephyr RTOS.
Then, he will try to address developers' concerns and tackle some common misconceptions they have. In addition, he will talk about the safety working group and how it aims to minimize the burden on contributors and maintainers while meeting certification requirements.
To finish, he will discuss the current initiatives and opportunities for community involvement in advancing functional safety support in Zephyr.

Zephyr and Xen in Automotive Mixed-OS Systems: Building Safety Readiness and Upstream - Harunobu Kurokawa, Renesas Electronics Corporation

Thursday October 8, 2026 09:50 - 10:30 CEST

South Hall 2 A (Floor 2)

In automotive systems, interest is growing in OSS adoption, Software-Defined Vehicles (SDV), and mixed-criticality architectures. In initiatives such as AGL and SoDeV, configurations combining Linux, RTOSes, and hypervisors are becoming a key focus. In this context, Zephyr may be used as a small RTOS domain with a limited, well-defined role.

This session views Zephyr and Xen as complementary components. Xen can provide domain isolation and resource partitioning, Linux can host high-level services and integration layers, and Zephyr can handle focused RTOS functions. It outlines role division in OSS-based automotive software.

Functional safety is also important. The Zephyr Safety WG is advancing related activities, treating safety readiness not as certification itself but as a technical foundation—requirements, tests, and documentation—that the community can build together. This session discusses how automotive stakeholders can participate and contribute upstream.

Based on Linux/AGL mixed-OS integration experience, this case study discusses what should be addressed when applying Zephyr and Xen to automotive systems and how these efforts can advance with the community.

Bringing IEC 60730 Class B Functional Safety To Zephyr - Andrej Butok, NXP Semiconductors

Thursday October 8, 2026 10:50 - 11:30 CEST

South Hall 2 A (Floor 2)

The IEC 60730 Class B standard defines safety requirements for automatic electrical controls in household appliances, mandating diagnostic mechanisms that ensure safe operation under fault conditions.
Despite its widespread adoption, IEC 60730 implementations remain fragmented and vendor-specific, typically delivered as proprietary libraries tightly coupled to individual MCUs. This approach limits portability, duplicates engineering effort, and prevents meaningful integration with modern open-source ecosystems.
This talk presents an open, reusable IEC 60730 Class B diagnostic framework built on Zephyr RTOS, demonstrating how functional safety mechanisms can be implemented in a portable and extensible way. The framework includes key diagnostics such as power-on self-tests, periodic runtime checks, watchdog supervision, and safe-state handling.
This work establishes a foundation for standardizing safety mechanisms in Zephyr and aims to catalyze community collaboration around common APIs and reference implementations for safety-critical embedded systems.
The session is targeted at embedded developers working on consumer appliances and industrial control systems.

Reverse Engineering Zephyr's Software Architecture for Safety-Critical Use - Roberto Bagnara, BUGSENG / University of Parma

Thursday October 8, 2026 11:40 - 12:20 CEST

South Hall 2 A (Floor 2)

Zephyr RTOS is increasingly relevant for safety-related and
mixed-criticality systems, where qualification and certification must
address standards such as IEC 61508 and ISO 26262. A key question is
how to provide evidence that software components are independent, that
freedom from interference is preserved, and that future changes can be
assessed without redoing unnecessary qualification work.

This session presents ongoing work on reverse engineering Zephyr's
effective software architectural constraints using static
analysis. Starting from concrete Zephyr configurations, we model
components, observe calls and data accesses, identify dependencies,
and compare the result with the project's intended layered
architecture.

The talk will show how this analysis supports safety arguments by
making software-level independence explicit and checkable. It will
also show how the same model enables Change Impact Analysis: when a
qualified Zephyr version or configuration evolves, the model helps
determine which components, assumptions, tests, and safety evidence
are affected. This is essential to make Zephyr's safety effort
sustainable over time and viable for safety-related development.

No Board, No Problem: Testing Zephyr Applications With Native_sim - Marco Widmer, bytes at work AG

Thursday October 8, 2026 13:50 - 14:30 CEST

South Hall 2 A (Floor 2)

Zephyr makes it easy to build the same code for multiple board targets. native_sim lets you run (parts of) your zephyr application and associated tests as a regular Linux process, allowing reproducible runs, easy debugging and CI integration.

In this talk, I will share what we learned structuring, testing, and debugging several real-world Zephyr applications:

* The native_sim execution model: How time is handled
* How to emulate hardware: Fake drivers, virtual bluetooth controllers, networking, PTY UART, emulators
* Examples of what can be built using these primitives:
* Connecting to the Android Emulator over BLE
* Writing Zephyr tests using the Cucumber framework
* ...
* Tooling around native_sim: twister, sanitizers, GDB, code coverage
* Integrating external binaries into twister through the pytest harness
* Designing for testability: Separating business logic from hardware-dependent software units
* When native_sim is not enough: Running tests in qemu or on real hardware

The goal of this talk is to provide a broad overview about what is possible thanks to native_sim, hopefully inspiring new ideas on how to test code without ever touching hardware.

Fake Drivers: A Practical Guide To Zephyr Test Doubles - Henrik Brix Andersen, Vestas Wind Systems A/S

Thursday October 8, 2026 14:40 - 15:20 CEST

South Hall 2 A (Floor 2)

In Zephyr, subsystems, middleware, and application components typically depend on one or more lower-level device driver APIs. For testing these upper-level subsystems in isolation, the lower-level driver dependencies must still be satisfied. A popular software design pattern for this is to use test doubles. However, how can this be achieved in Zephyr without introducing test-specific changes to the upper-level subsystem?

The solution is to use fake drivers. This presentation will explore various use cases for employing fake device drivers as test doubles, examine the structure of a fake driver implementation, and demonstrate how fake drivers can be used to not only satisfy test dependencies, but also facilitate test case isolation, driver API call inspection and instrumentation.

Stop Rewiring: Scale Embedded Hardware Testing - Franklin Cooper, Texas Instruments

Thursday October 8, 2026 15:50 - 16:30 CEST

South Hall 2 A (Floor 2)

Embedded test automation is often limited by something simple: wires. External loopback, testing another peripheral instance, validating a power domain, or connecting to external equipment can each require a different setup. As coverage grows, teams end up with custom fixtures, manual steps, fragile lab instructions, and CI systems that cannot reproduce a developer’s bench setup.

This talk presents an open source framework that uses a low-cost, off-the-shelf FPGA board as a programmable routing fabric. It sits between the device under test and the rest of the setup, routing pins to loopbacks, other peripherals, boards, or tools.

The framework is software-agnostic: it works with Zephyr, Linux, bare metal, or vendor SDK testing. Tests declare the needed connections, metadata describes the FPGA-to-device wiring, and the framework generates per-test Verilog, runs open source FPGA tools, and programs the FPGA.

The talk will cover lessons from real tests, common peripheral limits, demo and how to reproduce this setup at a desk, in a lab, or in CI.

Key benefits:
*Low-cost off-the-shelf hardware
*Open source software
*Easier developer desk testing
*More CI/CD regression coverage

ZView: Non-Intrusive Runtime Observability for Zephyr - Paulo Santos, EDGE-UFAL

Thursday October 8, 2026 16:40 - 17:20 CEST

South Hall 2 A (Floor 2)

Zephyr is a comprehensive ecosystem, but sometimes you want a better view of your system and end up reaching for shell, UART, printk, RTT, or tracing, all of which work, but all of which cost on-target code, pins, or configuration overhead, or even extra hardware.
ZView is a live, non-intrusive, low-integration-cost runtime observability tool that provides an overview of how your application behaves (threads, heaps, allocation and fragmentation, CPU usage, and more) all in a TUI, using only your debug probe via SWD.
It uses the debug access port to read kernel memory passively while the target keeps running. No instrumentation, no halt, no extra pins. ZView interprets what it reads, recognizing threads, heaps, and other kernel objects, turning raw memory into actionable runtime insights.
This talk covers what ZView is, how it works, its limits, and where it can go next. The goal is to make ZView a standard part of the Zephyr debugging toolkit, with the community's help.

Clocks in Zephyr: A Practical Guide for BSP Developers (Lesson Learned From a Real Porting) - Martin Hoff, Silicon Laboratories

Friday October 9, 2026 09:05 - 09:45 CEST

South Hall 2 A (Floor 2)

Clocks are easy to ignore until your first Zephyr BSP port — when UART, SPI, or DMA suddenly depend on device tree properties you have never touched.
This beginner-friendly talk explains how clocks work in Zephyr today: clocks as phandle-arrays (like pwms and gpios), the meaning of #clock-cells, and how DT macros connect DTS to driver code. We separate three everyday questions: enabling a clock, selecting its source, and reading its rate — mapped to clock_control_on(), clock_control_configure(), and get_rate().
We then cover practical porting decisions any SoC author faces: what to describe in device tree at boot, what to leave to runtime (for example power management), and common mistakes — wrong cells, gates versus muxes and over-modelling hardware in DT.
Finally, we look at where Zephyr is heading: RFCs for a Clock Management Subsystem propose richer clock trees and predefined clock states, closer to how silicon is wired. You will leave with a reusable mental model for today’s APIs and a map of tomorrow’s direction.
Audience: developers new to Zephyr, BSP porters, and device tree authors. No prior clock-driver experience required.

Apps, Not Firmware: A Service-Oriented Application Layer for Zephyr - Sylvio Alves, Espressif Systems

Friday October 9, 2026 09:50 - 10:20 CEST

South Hall 2 A (Floor 2)

Microcontroller firmware is monolithic: one image, one failure domain, where a bug anywhere can crash everything. Yet modern MCUs ship with memory protection (MPU, MMU, or PMP), and Zephyr already has the isolation pieces - userspace, memory domains, kernel-object capabilities, watchdogs, zbus - never assembled into an application model.

This talk presents a service-oriented application layer for Zephyr: multiple memory-isolated apps running as managed units, each reaching hardware and the network only through a capability-gated service broker, so a misbehaving app cannot corrupt, starve, or crash its neighbors.

We build the missing keystone - an app-group lifecycle and a service broker - on top of existing Zephyr, and demonstrate it live: two isolated apps share one Wi-Fi stack, each making independent network requests; one hangs and another faults, both are killed and reclaimed, while the healthy app runs on. We close with hardware lessons and upstreamable RFC targets.

Zenbedded: Bringing Ros2_control Closer To the Embedded World - Speakers to be Announced

Friday October 9, 2026 11:05 - 11:45 CEST

South Hall 2 A (Floor 2)

The Robot Operating System (ROS) is the de facto standard open-source middleware for building robot software, providing standardized messaging, tooling, and reusable components. ros2_control is a hardware-agnostic control framework focusing on the modular composition of control systems for robots, sharing of controllers as well as real-time performance.

Bringing ros2_control to embedded systems usually means bolting heavy DDS serialization and a bridge process onto microcontrollers. Zenbedded fixes this. It is a monolithic Zephyr, Zenoh, and ROS 2 framework built specifically for ros2_control. We put the transport, the RTOS client library, and the host-side hardware_interface plugin into one tight repository.
On the wire, we use a multi-tier transport that moves along a spectrum. You can choose between fully ROS-observable but slightly slower, or fully binary-encoded and fast, depending on what your control loop actually needs.
You'll leave with a pattern for running ros2_control on Zephyr-class hardware and a feel for working with ROS and ros2_control. We'll demo the stack balancing a real inverted pendulum on an ESP32, where latency is the difference between upright and toppled.

Libiio on Zephyr: A Unified API for Industrial I/O Across Linux and RTOS Targets - Maureen Helm & Pete Johanson, Analog Devices

Friday October 9, 2026 11:55 - 12:35 CEST

South Hall 2 A (Floor 2)

libiio is an open source C library developed by Analog Devices for interfacing with Industrial I/O (IIO) devices - ADCs, DACs, IMUs, RF transceivers, temperature sensors, and more. It underpins a broad ecosystem of host-side tools including Scopy, pyadi-iio, and MATLAB, all of which connect to targets over network, serial, or USB transports.

This talk walks through the architecture and practical mechanics of the port. We will cover how libiio's external backend integrates with Zephyr's device model, allowing any driver that implements the IIO device driver API to appear as a first-class IIO device. We will look at built-in bridge drivers that wrap any Zephyr ADC, DAC, or sensor device into an IIO device. We will also cover how the module integrates into the Zephyr build system using Kconfig, device tree, and snippets to enable libiio with minimal changes to an application.

We will demonstrate a Zephyr board being queried from Scopy and pyadi-iio, and close with a look at what is in progress - trigger support for deterministic sampling and streaming, and a USB transport as a complement to the existing UART and network transports.

Crash Dumps Without Cables: Live Coredump Capture Over UDP/Ethernet in Zephyr RTOS - Kedareswara Rao Appana, AMD

Friday October 9, 2026 16:00 - 16:20 CEST

South Hall 2 A (Floor 2)

When an embedded system crashes in the field, recovering the coredump often determines whether debugging takes hours or weeks. Zephyr has long supported coredumps over UART, but in modern industrial, IoT, and edge deployments the serial port is rarely accessible. Devices may be sealed in cabinets, deployed remotely, or connected only via network.

This talk introduces a new Zephyr coredump backend that streams crash data over UDP (IPv4/IPv6) at the moment of a fatal exception—no USB cable or physical access required. We will explore the design challenges of networking in the fatal path, including safely re-enabling interrupts so the NIC can transmit, and the ZCDU framing protocol used to packetize and reliably reassemble dumps from UDP datagrams. We also show how the host receiver integrates seamlessly with the existing Zephyr GDB workflow, making the switch from UART to Ethernet a simple Kconfig option. Attendees will learn how to enable fleet-scale crash capture and dramatically reduce time-to-root-cause for deployed Zephyr devices.

Our Zephyr firmware targets proFPGA systems programmed via Windows-only scripts, Protium emulators on Linux servers with J-Links on Windows machines, MAX32xxx boards on Linux, and virtual platforms. Discrete teams — hardware, virtual platform, proFPGA, Protium, bare-metal, Debugger Scripts, and Zephyr — each own a different piece on different platforms.

We built CI that unifies all of this so a developer opening a PR gets feedback from real hardware regardless of board, country, or OS. The talk covers device-specific flashing automation, reusable workflows scaling from PRs to nightly runs, observability beyond pass/fail (memory footprint tracking, runner dashboards, test analytics), and the technical interfaces between teams that make it sustainable.

Every pattern is in production today, testing across 28+ boards in multiple countries and different toolchains on every pull request.
