How V4L2 Transformed To Support Embedded Cameras - Laurent Pinchart, Ideas on Board

Tuesday August 26, 2025 11:00 - 11:40 CEST

Elicium 1

Cameras in today's embedded devices are made of increasingly complex hardware. The V4L2 API has constantly evolved since its birth nearly 25 years ago to support the needs of this ever-changing landscape. What has however not changed much is the impression that V4L2 is the same today as it was 10 years ago, and that it can't adapt to modern devices.

This talk will rectify this misconception by presenting all the recent features of the V4L2 API relevant to cameras in embedded systems. We will cover raw image sensors with complex processing features (such as HDR or NPU), streams multiplexing, powerful ISPs, complex pipelines of serializers and deserializers, multi-context image processing, and more. Examples will focus not just on wishful thinking for the future, but on open solutions that are developed and ship today.

Attendees will see how to support embedded cameras on Linux with mainline kernels and without closed-source stacks, learn which APIs they need for their use cases and how to use them, and hear about ongoing V4L2 developments and where the API is heading for the future.

Securing Europe's Open Source Infrastructure: A Technical Case for an EU-Wide Sovereign Tech Fund - Nick Gates, OpenForum Europe & Felix Reda, GitHub

Tuesday August 26, 2025 11:00 - 11:40 CEST

Auditorium

This session examines the proposed EU Sovereign Tech Fund (EU-STF), a mechanism inspired by Germany's Sovereign Tech Agency to address critical maintenance gaps in open source components underpinning European digital infrastructure.

Technical findings from a June 2025 feasibility study will be surveyed, which reveal the economic, legal, and political arguments for implementing an EU-wide Sovereign Tech Fund. Then, expert panelists will unpack the technical architecture of this maintenance crisis, demonstrating how the proposed EU-STF creates practical mechanisms for collaborative public-private efforts, as well as key use cases.

Attendees will learn implementation models that bridge the gap between how developers understand maintenance challenges (technical debt, security vulnerabilities, dependency management) and how policymakers frame these issues (resilience, sovereignty, compliance). They will gain actionable insights into:

-- How public FOSS funds need to be designed to reach critical but under-resourced components

-- Aligning the goals of FOSS maintenance funding to the needs of developers and policymakers

-- How to help make the EU-STF a reality

ManaTEE: Enabling Verifiable AI Transparency With Confidential Computing - Dayeol Lee & Mingshen Sun, TikTok

Tuesday August 26, 2025 11:55 - 12:35 CEST

TBA

ManaTEE is an open-source framework that enables private data analytics for public research using Trusted Execution Environments (TEEs). In this talk, we show how ManaTEE supports verifiable AI transparency, especially for proprietary models where open inspection is not feasible. TEEs allow sensitive model evaluation and data analysis in isolated, secure environments with cryptographic attestation, ensuring the integrity of both the model and data. This enables external researchers and auditors to assess AI systems without direct access to the model or sensitive data. ManaTEE simplifies this process with a secure, interactive Jupyter Notebook interface where users can load benchmarks, write evaluation code, and analyze results—preserving data confidentiality and model secrecy. We will demo how ManaTEE evaluates a closed-source AI model in a reproducible and auditable way, helping balance the need for transparency with confidentiality.

The Power of the Device Mapper - From Dm-cache To Dm-zoned - Werner Fischer, Thomas-Krenn.AG

Tuesday August 26, 2025 11:55 - 12:35 CEST

G102-103

The device mapper has been part of the Linux kernel since kernel version 2.6. It allows the creation of virtual block devices by mapping their address space to other block devices or special functions. In this way, it can map physical block devices such as hard disks or SSDs to higher-level virtual block devices. It is the basis for the Logical Volume Manager (LVM), Linux software RAIDs and dm-crypt encryption, and provides additional features such as file system snapshots.

However, the use of Device Mapper targets is not limited to that. Many other targets offer often unknown features. Most of these are intended for production use. However, there are also some targets designed specifically for debugging.

In this talk, Werner gives a full overview of all Device Mapper targets.

For production use these are: dm-cachd, dm-clone, dm-crypt, dm-ebs, dm-era, dm-integrity, dm-linear, dm-mirror, dm-raid, dm-stripe, dm-switch, dm-thin, dm-unstripe, dm-verity, dm-vdo, dm-writecache and dm-zoned.

For debugging: dm-delay, dm-dust, dm-flakey and dm-zero.

He also briefly shows drbd, md (RAID) and bcache, which, like device mapper targets, can work as devices "on top" of normal block devices.

No Internet - No Problem? Air-Gapped Kubernetes on Bare Metal - Christian Bendieck & Carolin Dohmen, BWI GmbH

Tuesday August 26, 2025 14:10 - 14:50 CEST

G001-002

What do you do when connectivity isn’t just flaky – it’s nonexistent? In this talk, we’ll take you through our experience deploying fully automated, air-gapped Kubernetes clusters on bare metal servers – without internet access, without a pre-existing registry, and minimal reliance on datacenter services such as NTP.

As the IT provider for the German Armed Forces, we operate in environments where isolation isn't optional – it's mandatory. Whether due to strict security requirements or the literal ocean between hardware and surface.

At the heart of our setup is a purpose built origin node based on NixOS – which provides all necessary external services to bootstrap the cluster leveraging Talos OS.

This session will cover the technical architecture, the automation stack, and some of the challenges we faced, including:

- Bootstrapping from air-gapped nothingness

- Pitfalls and amazement of Nix and NixOS

- Talos quirks such as image caching limitations

- The joys of automating server setup by accessing BMCs with the Redfish API

- Considerations of NeoNephos projects for further development

You'll leave with practical insights for spinning up fully disconnected Kubernetes clusters.

Server Partitioning Without VMs - for Flexibility and Performance - Antti Kervinen, Intel & Feruzjon Muyassarov, Ericsson Software Technology

Tuesday August 26, 2025 14:10 - 14:50 CEST

Emerald Room

Efficient use of servers with tens or hundreads of CPUs most often requires partitioning it so that only a fraction of CPUs is disclosed to a set of containers. This improves performance, hardware utilization, and mitigates the noisy neighbor problem.

In this session, you will learn about very flexible CPU and memory partitioning that enables squeezing maximum performance from the server. For instance, you will see how to arrange containers into dynamically growing and shrinking CPU sets. How to group containers into CPU sets based on their names, labels, QoS classes, or namespaces. How to pre-allocate isolated CPUs for latency critical containers. How to let containers burst outside their partitions if there are free CPUs. And without forgetting observability, how to view existing partitions in the cluster in detail, including exact CPUs and containers in each partition.

We use NRI plugins and the balloons policy for demonstrating this, without limitations of Kubernetes CPU manager, or overhead of VMs. That said, this partitioning makes sense inside large VMs, too.

Extending Container Performance Isolation: Regulating Memory Bandwidth & Cache in the Kernel - Jonathan Perry, Unvariance

Tuesday August 26, 2025 14:10 - 14:50 CEST

G102-103

While containers provide isolation for CPU cycles and memory capacity, they offer limited protection against performance interference through shared CPU caches and memory bandwidth. Such contention was shown to increase application response times by 4-13x. The Linux resctrl infrastructure provides monitoring and control mechanisms, but has limitations for controlling real-world applications.

For example, child processes do not inherit their parent's resctrl groups, leaving any application that forks improperly monitored and controlled. Additionally, the current filesystem-based interface makes it difficult to build a controller that can monitor and adjust quickly enough to keep up with frequently changing application memory behavior.

This talk introduces the memory interference problem and presents new kernel mechanisms to address these limitations. A new collector enables effective control by capturing per-container measurements of cache and memory bandwidth usage at millisecond frequencies. We'll cover how the solution combines Intel RDT, AMD QoS, high-resolution timers, perf counters, and cgroups to achieve this. We'll discuss future work and opportunities for collaboration.

More Effective Approach To Detecting Potential Deadlocks, DEPT(DEPendency Tracker) - Byungchul Park, SK hynix

Tuesday August 26, 2025 15:05 - 15:45 CEST

G104

Lockdep is a tool in the Linux kernel designed to detect potential deadlocks by tracking the order in which locks are acquired. However, deadlocks can occur not only due to incorrect lock acquisition order, but also from waits that cannot be resolved. For more effective deadlock detection, it is crucial to track the waits and events themselves, rather than focusing on lock acquisition order. This is where DEPT (DEPendency Tracker) comes in. DEPT accurately identifies conditions that can lead to deadlocks by tracking waits and events. Let me introduce DEPT and explain how it works.

Zero Trust at the Edge: Bridging Industrial Systems With Verifiable Credentials and OpenZiti - Shane Deconinck, Howest University of Applied Sciences

Tuesday August 26, 2025 16:20 - 17:00 CEST

TBA

Industrial environments depend on secure collaboration among internal employees and external technicians. Traditional centralized identity systems like LDAP fall short when managing external parties, while industrial constraints prevent modifying legacy equipment.

This session presents a pragmatic architecture using open-source tools - including OpenZiti and W3C Verifiable Credentials (VCs) - to enforce Zero Trust precisely at the application level. By combining decentralized identity management for external supplier technicians with corporate OIDC for internal staff, we demonstrate how to achieve secure, identity-aware communication flows without rewriting legacy MQTT hardware.

Attendees will learn how application-level binding ensures that only explicitly authorized actions occur, preventing any unauthorized bypass even in constrained industrial setups. The approach not only strengthens security in today’s complex environments but also boosts the value and potential of these emerging technologies through practical integration.
