1 like405 views
If you heard something about Yocto, bitbake, openembedded, layers, recipes and you want to know more about that, this talk is for you. In this presentation you will be introduced to the Yocto Project build system starting from the basic concepts of metadata up to the use of the build system “tasks” in order to create your own embedded linux distribution. I will start speaking about the pros and cons of the Yocto Project compared to the other embedded linux build systems. Then we go deep into the framework components: poky, openembedded core and bitbake. The practical use of the recipes, packagegroups, images and machines files will be explained by examples. Finally an example on how to integrate an extra layer will be showed demonstrating the ease of use and the modularity of the build system.

Clay D. Montgomery, Freelance Embedded Multimedia Developer at Montgomery One, presents the "Building Complete Embedded Vision Systems on Linux—From Camera to Display" tutorial at the May 2019 Embedded Vision Summit.
There’s a huge wealth of open-source software components available today for embedding vision on the latest SoCs from suppliers such as NXP, Broadcom, TI and NVIDIA, at lower power and cost points than ever before. Testing vision algorithms is the first step, but what about the rest of your system? In this talk, Montgomery considers the best open-source components available today and explains how to select and integrate them to build complete video pipelines on Linux—from camera to display—while maximizing performance.
Montgomery examines and compares popular open-source libraries for vision, including Yocto, ffmpeg, gstreamer, V4L2, OpenCV, OpenVX, OpenCL and OpenGL. Which components do you need and why? He also summarizes the steps required to build and test complete video pipelines, common integration problems to avoid and how to work around issues to get the best performance possible on embedded systems.

Kernel Recipes 2019 - No NMI? No Problem! – Implementing Arm64 Pseudo-NMI
Kernel Recipes 2019 - No NMI? No Problem! – Implementing Arm64 Pseudo-NMIAnne Nicolas As the name would suggest, a Non-Maskable Interrupt (NMI) is an interrupt-like feature that is unaffected by the disabling of classic interrupts. In Linux, NMIs are involved in some features such as performance event monitoring, hard-lockup detector, on demand state dumping, etc… Their potential to fire when least expected can fill the most seasoned kernel hackers with dread.
AArch64 (aka arm64 in the Linux tree) does not provide architected NMIs, a consequence being that features benefiting from NMIs see their use limited on AArch64. However, the Arm Generic Interrupt Controller (GIC) supports interrupt prioritization and masking, which, among other things, provides a way to control whether or not a set of interrupts can be signaled to a CPU.
This talk will cover how, using the GIC interrupt priorities, we provide a way to configure some interrupts to behave in an NMI-like manner on AArch64. We’ll discuss the implementation, some of the complications that ensued and also some of the benefits obtained from it.

Based on practical examples, this talk intends to provide a ""getting started guide"" for newcomers in the Device Tree world: what is the Device Tree? How is it written and compiled? How do the bootloader and kernel interact? How are Device Tree bindings written and documented? What are the best practices for writing Device Trees and their bindings?

The Latest Status of CE Workgroup Shared Embedded Linux Distribution Project
The Latest Status of CE Workgroup Shared Embedded Linux Distribution ProjectYoshitake Kobayashi The CE workgroup of Linux Foundation has started a project to share the work of maintaining long-term support for an embedded distribution, by leveraging the work of the Debian and Debian LTS project. Debian gives you pre-compiled binary packages but the meta-debian layer enables to install customized packages to create similar or smaller images. If both usecases are able to share the source code, it is good to share the maintenance effort.
In this talk, Yoshitake will describe the details of meta-debian which provides a meta layer for the Poky build system. This talk will to gives the latest status, technical details and lessons learned from its development.
All source code are available on GitHub and related document also available on Github and elinux wiki.

Yocto_DevDay_Advanced_Class_Portland_2018.pptx
Yocto_DevDay_Advanced_Class_Portland_2018.pptxRajeshravi49 Bhakti (Sanskrit: भक्ति; Pali: bhatti) is a term common in Indian religions which means attachment, fondness for, devotion to, trust, homage, worship, piety, faith, or love.[1] In Indian religions, it may refer to loving devotion for a personal God (like Krishna or Devi), a formless ultimate reality (like Nirguna Brahman or the Sikh God) or for an enlightened being (like a Buddha, a bodhisattva, or a guru).[2][3][4][5][6][7] Bhakti is often a deeply emotional devotion based on a relationship between a devotee and the object of devotion.[8][9][10]
One of the earliest appearances of the term is found in the early Buddhist Theragatha (Verses of the Elders).[11] In ancient texts such as the Shvetashvatara Upanishad, the term simply means participation, devotion and love for any endeavor, while in the Bhagavad Gita, it connotes one of the possible paths of spirituality and towards moksha, as in bhakti marga.[12]
Bhakti ideas have inspired many popular texts and saint-poets in India. The Bhagavata Purana, for example, is a Krishna-related text associated with the Bhakti movement in Hinduism.[13] Bhakti is also found in other religions practiced in India,[14][15][16] and it has influenced interactions between Christianity and Hinduism in the modern era.[17][18] Nirguni bhakti (devotion to the divine without attributes) is found in Sikhism, as well as Hinduism.[19][7] Outside India, emotional devotion is found in some Southeast Asian and East Asian Buddhist traditions.[4][5][20]
The term also refers to a movement, pioneered by the Tamil Alvars and Nayanars, that developed around the gods Vishnu (Vaishnavism), Shiva (Shaivism) and Devi (Shaktism) in the second half of the 1st millennium CE.[2][3][21][22][23][24]
Devotional elements similar to bhakti have been part of various world religions throughout human history.[25] Devotional practices are found in Christianity,[25][26] Islam,[27][28] Buddhism[29][30][31] and Judaism.[25][32] Bhakti (Sanskrit: भक्ति; Pali: bhatti) is a term common in Indian religions which means attachment, fondness for, devotion to, trust, homage, worship, piety, faith, or love.[1] In Indian religions, it may refer to loving devotion for a personal God (like Krishna or Devi), a formless ultimate reality (like Nirguna Brahman or the Sikh God) or for an enlightened being (like a Buddha, a bodhisattva, or a guru).[2][3][4][5][6][7] Bhakti is often a deeply emotional devotion based on a relationship between a devotee and the object of devotion.[8][9][10]

Building Emmbedded Linux with Yocto project
Building Emmbedded Linux with Yocto projecttwcoimbatore Embedded Linux uses the Linux kernel and open source components in embedded systems. It manages hardware and provides system calls and event notification. Building embedded Linux involves challenges like placing the bootloader, configuring the kernel, choosing init programs and filesystems, and resolving dependencies. The Yocto Project provides templates, tools, and methods to build embedded images. It uses BitBake, metadata, and configurations. Recipes define how software is built, packaged, and installed into images. Hands-on examples demonstrate building a sample application, customizing an image, and making the application start at boot.
OpenEmbedded & BitBake - Denx
OpenEmbedded & BitBake - Denxyang firo OpenEmbedded and BitBake are open source tools used to build Linux distributions for embedded systems. BitBake controls the build process by executing tasks based on recipes. It collects build descriptions from recipes and dependencies to compile packages in the proper order. OpenEmbedded contains metadata like build classes, machine configurations, and recipes that define how to cross-compile, package, and install software for complete embedded Linux distributions.

Generating a Reproducible and Maintainable Embedded Linux Environment with Po...LF Events For civil infrastructure system related products, kernel and open source software included in the system requires not only industrial grade but also super long term support. We have developed a meta layer for Poky build system which can uses the Debian’s source codes to share long term maintenance effort. However, there is an issue on source code management for product development which relates on reproducibility and maintainability. We have some experiences in product maintenance phase, for example, a bug occurred more than three years later after the product was released. In such kind of case, if we can reproduce the Linux environment for any older version, it is useful to find the source of issue.
In this talk, we will explain how to manage source codes and how to generate an embedded Linux environment with Poky and Deby for long term maintenance.

Bruno Verachten - The Android device farm that fits in a (cloudy) pocket
Bruno Verachten - The Android device farm that fits in a (cloudy) pocketlinuxlab_conf Android developers are facing a common problem: how to test our applications on many devices without sacrificing too much time or money? Could we use remotely all the devices inside the company with the continuous integration system? Maybe thanks to a low cost device farm that fits into a pocket?
Android developers are facing a common problem: how to test our applications on many devices without sacrificing too much time or money?
How to build and test automatically our applications for each commit? How can we find those devices inside the company, whatever its size may be? Could there be a directory somewhere that lists those available devices? Could we use a device remotely and share it with other developers as if it were in the cloud? What if you could answer all these questions with the help of a low cost device farm that fits into a pocket? A pocket full of clouds…
Poddingue, our proposal, aims to tackle this problem thanks to Docker, HypriotOS, Armbian, Gitlab CI and OpenSTF. It’s an internal solution made of OSS readily available, but it has not yet been publicly announced as a whole.
This is a feedback about an idea on its way to production, a long journey full of different feelings : horror, happiness, suspense, boredom…
Why should I come? This presentation won’t be too technical ; it is opened to anybody who has an interest into Android, exotic hardware or continuous integration, as long as you can stand a bad sense of humour. At the end of the talk, you should know how to build your own cloudy pocket farm of Android devices and how to use it to test your applications within your ci pipeline.
And as I am cheap, you will also be surprised at how little money you need to build it.
Claudio Scordino - Handling mixed criticality on embedded multi-core systems
Claudio Scordino - Handling mixed criticality on embedded multi-core systemslinuxlab_conf This talk illustrates how to use the Jailhouse hypervisor for running Linux alongside an RTOS on modern ARM multi-core SoCs, aiming at building smarter devices for the automotive market.
Recently, the industry has shown a growing interest for executing activities with different levels of criticality on the same multi-core SoC. These could consist, for example, of non-critical activities (e.g., monitoring, logging, human-machine intefaces) together with safety-critical tasks. The rationale behind this interest is the continuous need for reducing the time-to-market as well as the design and hardware costs. This is particularly suitable for the automotive market, where new infotainment functionalities might be coupled with traditional safety-critical tasks (e.g. engine/brake control). In this talk, we will present our experience (grown through the HERCULES EU project) in using the Jailhouse hypervisor for executing the Linux general-purpose OS alongside an automotive RTOS on modern ARM multi-core platforms. Besides providing useful instructions for using Jailhouse, we will illustrate a library designed for easing the communication between the two OSs as well as some mechanism for limiting the interference on shared hardware resources. Finally, a short video of a simple demo will show the effectiveness of the proposed approach.
Andrea Righi - Spying on the Linux kernel for fun and profit
Andrea Righi - Spying on the Linux kernel for fun and profitlinuxlab_conf Do you ever wonder what the kernel is doing while your code is running? This talk will explore some methodologies and techniques (eBPF, ftrace, etc.) to look under the hood of the Linux kernel and understand what it’s actually doing behind the scenes.
This talk explores methodologies that allow to take a look “live” at kernel internal operations, from a network perspective, to I/O paths, CPU usage, memory allocations, etc., using in-kernel technologies, like eBPF and ftrace. Understanding such kernel internals can be really helpful to track down performance bottlenecks, debug system failures and it can be also a very effective way to approach to kernel development.
Jacopo Mondi - Complex cameras are complex
Jacopo Mondi - Complex cameras are complexlinuxlab_conf The ‘complex camera’ user-space library is a fairly new and hot topic in the Linux kernel video community. The issue is debated and targets a real technical debt of Linux systems.
The Linux kernel video input subsystem and its APIs changed greatly in the last years to keep up with the increasing complexity and processing power embedded in modern SoCs. Namely, the biggest game-changing feature introduced already 5 years ago is the media controller subsystem and its pad oriented APIs, that allows composing pipelines of processing blocks to model the acquisition and re-processing of video and images.
While most of the media subsystem drivers in mainline Linux have been ported to fully support media-controller, the real missing component is now user space support to automate setting up and controlling the image processing pipelines.
The Video4Linux community is now tackling the issue by implementing support for “complex camera” systems by providing a user space library that aims to support the most recent use cases represented by mobile consumer devices and high end laptops.
This talks provides an overview of the in-kernel APIs of modern media-controller capable video device drivers, their userspace APIs and the challenges the currently in-development library has to face.
It also aims to provide to both driver and application developers an overview of the most modern implementation of the Linux video input stack architecture, that will likely be found in most system in next years.

Emanuele Faranda - Creating network overlays with IoT devices using N2N
Emanuele Faranda - Creating network overlays with IoT devices using N2Nlinuxlab_conf When building a network of communicating IoT devices, it is compulsory to ensure that all the devices are reachable regardless of their IP address and location. This talk is about an open source software named n2n that enables secure communication over a lightweight and secure p2p network overlay.
When building a network of IoT devices, communication topology can be a problem as some of them might be behind a NAT, and some others might be reachable only from certain network nodes. Furthermore the advent of mobile and automotive computing with non persistent addressing will make all this even more challenging. To address all this, usually people use a centralised cloud-based topology that makes the network weak and not optimal, as all the devices have to communicate though this central point instead, when possible, to talk directly. However the cloud does not address privacy and security, in particular when IoT devices are used and developers and not fully aware of security issues: this can be addressed by a network overlay that tackles this problem at network instead that at application level This talk is about an open source, lightweight network overlay software named n2n ( https://github.com/ntop/n2n ) [available for Linux, BSD, MacOS, Windows] developed by the authors, that enables the creation of a persistent network that promotes secure communications even on environments where security is an option, or some communications are prevented by NATs or firewall devices.

This talk will introduce some common exploits and techniques, showing the mitigations employed by the kernel. By focusing on the major threats that affects modern Linux boxes, we will see which are the main features that can give problems to the system administator and how a preliminary penetration test can be done, ensuring that the system is in a sane state. The talk will also focus on problematics of embedded/IoT Unix systems, showing how some recent attacks gained control over a big network of devices and how a simple embedded system can be analyzed, hunting for bugs. Talk outline: Penetration testing, Linux, netfilter/bpf, memory corruption, ASLR, Spectre/Meltdown.
Luca Abeni - Real-Time Virtual Machines with Linux and kvm
Luca Abeni - Real-Time Virtual Machines with Linux and kvmlinuxlab_conf This talk describes how to use some available technologies (the SCHED_DEADLINE scheduling policy, the PREEMPT_RT patchset, etc…) to execute real-time applications in kvm-based virtual machines while still providing performance guarantees to the virtualized applications.
In recent years, there has been a growing interest in supporting virtualized services even in embedded and real-time systems. However, executing real-time applications (characterized by temporal constraints) in virtual machines is not straightforward and presents some non-trivial challenges. This talk will describe how to use some technologies already available in the Linux kernel (the SCHED_DEADLINE scheduling policy, the PREEMPT_RT patchset, etc…) to execute real-time applications in kvm-based virtual machines while still providing performance guarantees to the virtualized applications. After presenting the problem (and providing a quick summary about real-time scheduling), it will be shown how to configure the host and guest kernels and the virtual machine, and how to schedule the VM threads in order to achieve predictable response times and to provide real-time guarantees.

TestMigrationsInPy: A Dataset of Test Migrations from Unittest to Pytest (MSR...Andre Hora Unittest and pytest are the most popular testing frameworks in Python. Overall, pytest provides some advantages, including simpler assertion, reuse of fixtures, and interoperability. Due to such benefits, multiple projects in the Python ecosystem have migrated from unittest to pytest. To facilitate the migration, pytest can also run unittest tests, thus, the migration can happen gradually over time. However, the migration can be timeconsuming and take a long time to conclude. In this context, projects would benefit from automated solutions to support the migration process. In this paper, we propose TestMigrationsInPy, a dataset of test migrations from unittest to pytest. TestMigrationsInPy contains 923 real-world migrations performed by developers. Future research proposing novel solutions to migrate frameworks in Python can rely on TestMigrationsInPy as a ground truth. Moreover, as TestMigrationsInPy includes information about the migration type (e.g., changes in assertions or fixtures), our dataset enables novel solutions to be verified effectively, for instance, from simpler assertion migrations to more complex fixture migrations. TestMigrationsInPy is publicly available at: https://github.com/altinoalvesjunior/TestMigrationsInPy.

How Valletta helped healthcare SaaS to transform QA and compliance to grow wi...Egor Kaleynik This case study explores how we partnered with a mid-sized U.S. healthcare SaaS provider to help them scale from a successful pilot phase to supporting over 10,000 users—while meeting strict HIPAA compliance requirements.
Faced with slow, manual testing cycles, frequent regression bugs, and looming audit risks, their growth was at risk. Their existing QA processes couldn’t keep up with the complexity of real-time biometric data handling, and earlier automation attempts had failed due to unreliable tools and fragmented workflows.
We stepped in to deliver a full QA and DevOps transformation. Our team replaced their fragile legacy tests with Testim’s self-healing automation, integrated Postman and OWASP ZAP into Jenkins pipelines for continuous API and security validation, and leveraged AWS Device Farm for real-device, region-specific compliance testing. Custom deployment scripts gave them control over rollouts without relying on heavy CI/CD infrastructure.
The result? Test cycle times were reduced from 3 days to just 8 hours, regression bugs dropped by 40%, and they passed their first HIPAA audit without issue—unlocking faster contract signings and enabling them to expand confidently. More than just a technical upgrade, this project embedded compliance into every phase of development, proving that SaaS providers in regulated industries can scale fast and stay secure.
Scaling GraphRAG: Efficient Knowledge Retrieval for Enterprise AI
Scaling GraphRAG: Efficient Knowledge Retrieval for Enterprise AIdanshalev If we were building a GenAI stack today, we'd start with one question: Can your retrieval system handle multi-hop logic?
Trick question, b/c most can’t. They treat retrieval as nearest-neighbor search.
Today, we discussed scaling #GraphRAG at AWS DevOps Day, and the takeaway is clear: VectorRAG is naive, lacks domain awareness, and can’t handle full dataset retrieval.
GraphRAG builds a knowledge graph from source documents, allowing for a deeper understanding of the data + higher accuracy.
Exceptional Behaviors: How Frequently Are They Tested? (AST 2025)
Exceptional Behaviors: How Frequently Are They Tested? (AST 2025)Andre Hora Exceptions allow developers to handle error cases expected to occur infrequently. Ideally, good test suites should test both normal and exceptional behaviors to catch more bugs and avoid regressions. While current research analyzes exceptions that propagate to tests, it does not explore other exceptions that do not reach the tests. In this paper, we provide an empirical study to explore how frequently exceptional behaviors are tested in real-world systems. We consider both exceptions that propagate to tests and the ones that do not reach the tests. For this purpose, we run an instrumented version of test suites, monitor their execution, and collect information about the exceptions raised at runtime. We analyze the test suites of 25 Python systems, covering 5,372 executed methods, 17.9M calls, and 1.4M raised exceptions. We find that 21.4% of the executed methods do raise exceptions at runtime. In methods that raise exceptions, on the median, 1 in 10 calls exercise exceptional behaviors. Close to 80% of the methods that raise exceptions do so infrequently, but about 20% raise exceptions more frequently. Finally, we provide implications for researchers and practitioners. We suggest developing novel tools to support exercising exceptional behaviors and refactoring expensive try/except blocks. We also call attention to the fact that exception-raising behaviors are not necessarily “abnormal” or rare.

Who Watches the Watchmen (SciFiDevCon 2025)
Who Watches the Watchmen (SciFiDevCon 2025)Allon Mureinik Tests, especially unit tests, are the developers’ superheroes. They allow us to mess around with our code and keep us safe.
We often trust them with the safety of our codebase, but how do we know that we should? How do we know that this trust is well-deserved?
Enter mutation testing – by intentionally injecting harmful mutations into our code and seeing if they are caught by the tests, we can evaluate the quality of the safety net they provide. By watching the watchmen, we can make sure our tests really protect us, and we aren’t just green-washing our IDEs to a false sense of security.

Explaining GitHub Actions Failures with Large Language Models Challenges, In...ssuserb14185 GitHub Actions (GA) has become the de facto tool that developers use to automate software workflows, seamlessly building, testing, and deploying code. Yet when GA fails, it disrupts development, causing delays and driving up costs. Diagnosing failures becomes especially challenging because error logs are often long, complex and unstructured. Given these difficulties, this study explores the potential of large language models (LLMs) to generate correct, clear, concise, and actionable contextual descriptions (or summaries) for GA failures, focusing on developers’ perceptions of their feasibility and usefulness. Our results show that over 80% of developers rated LLM explanations positively in terms of correctness for simpler/small logs. Overall, our findings suggest that LLMs can feasibly assist developers in understanding common GA errors, thus, potentially reducing manual analysis. However, we also found that improved reasoning abilities are needed to support more complex CI/CD scenarios. For instance, less experienced developers tend to be more positive on the described context, while seasoned developers prefer concise summaries. Overall, our work offers key insights for researchers enhancing LLM reasoning, particularly in adapting explanations to user expertise.
