In this session, we will discuss various practical ways of building the Linux kernel in the Yocto Project. We will cover building a traditional git tree and defconfig, an out-of-tree kernel module, a linux-yocto based kernel, adding kernel fragments for additional functionality and other common workflow patterns. This session will be a combination of a talk and hands-on labs. yocto-project-summit-2022-05-18395-hands-on-kernel-lab-introduction-to-linux-yocto-kernel-config-fragments-and-common-workflow-patterns Hands on Lab /media/yocto-project-summit-2022-05/submissions/G3RWFJ/yocto-tux_IUxVIgK.png Tim Orling en The linux-yocto workflow is a powerful and flexible way to provide a consistent kernel experience across many platforms. But the use of yocto-kernel-cache metadata (a structured tree of kernel fragments) and the linux-yocto git repository often confuses newcomers to the Yocto Project. Many traditional developers prefer to use “a git tree and a defconfig” to build their kernel, so we will also cover this use case. Individual platforms will also differ in the use of bootloader, device tree and other details that involve where the kernel is installed and how it is booted. We will give hands-on practical examples of these use cases to help you on your journey to creating and working with well-behaved Yocto Project BSP layers. false YPS Kernel Lab Slides (PDF) https://pretalx.com/yocto-project-summit-2022-05/talk/G3RWFJ/ https://pretalx.com/yocto-project-summit-2022-05/talk/G3RWFJ/feedback/ Kirkstone Lightning Talk 2022-05-18T12:00:00+00:00 12:00 00:15 A quick welcome on the first day of presentations. yocto-project-summit-2022-05-18505-welcome-day-1 All Attendees Trevor Woerner en A quick welcome on the first day of presentations. false https://pretalx.com/yocto-project-summit-2022-05/talk/EPXWKE/ https://pretalx.com/yocto-project-summit-2022-05/talk/EPXWKE/feedback/ Kirkstone Talk 2022-05-18T12:20:00+00:00 12:20 00:30 Recipes and configurations are the building blocks of Yocto distributions and Bitbake is the working machine that takes these blocks and assembles them.

This is a a Yocto / OpenEmbedded layer which provides support for Mono, an "open source implementation of Microsoft's .NET Framework based on the ECMA standards for C# and the Common Language Runtime". Also, more recently, Microsoft's dotNet is supported, "a free, cross-platform, open source developer platform for building many different types of applications. With . NET, you can use multiple languages, editors, and libraries to build for web, mobile, desktop, games, and IoT" Over the years I've had quite a lot of trouble ensuring that new releases of Mono ran properly for the community. It was taking a lot of my time to build for different architectures, with different releases of Yocto, and to test and make sure things were minimally OK. I've tried some different approaches over time, including cloud build providers and my own Jenkins installations. But now I've finally come to where I've always wanted to be: With GitHub Actions workflows, leveraging self hosted runners on my own cloud hardware to build and test. When contributors create a pull request multiple builds are kicked off (qemu-x86-64 and qemu-arm). These are then run up in architecture-specic QEMU virtual machines and a set of simple tests run using the Yocto Test Environment. It makes life much easier doing some pre-qualification for contributions and makes me feel more confident that I can keep things working. false Presentation Slides (ODP) Presentation Slides (PDF) https://pretalx.com/yocto-project-summit-2022-05/talk/RFUQUB/ https://pretalx.com/yocto-project-summit-2022-05/talk/RFUQUB/feedback/ Kirkstone Talk 2022-05-18T15:25:00+00:00 15:25 00:30 Yocto/OE is a powerful tool which can cover a wide array of tasks related to generating and developing software for a wide range of devices. All that power comes with the cost which has to be paid in the form of complexities when dealing with the system. To put it simply, Yocto is not simple. One complexity one has to deal with in Yocto is managing layers and local configuration files when starting a new project. The “repo tool” and git submodules combined with a skilled use of TEMPLATECONF do alleviate some problems, but intuitive was never quite the word to describe that flow. kas adds a layer of abstraction making it much easier to share a yocto project and help you get started with a build. At the same time it doesn’t sacrifice agility to gain that simplicity. You can build the entire project with a single command. At the same time, you’re one command away from an initialized bitbake environment if you need to deep dive the classical way. In this talk we will present the basic usage of kas, explore how the tool is used and show a few convenient flows that can come from using it. yocto-project-summit-2022-05-18221-using-kas-to-make-yocto-more-manageable Alan Martinovic en This presentation will give the embedded Linux development community an alternative of how to handle Yocto based projects.

This session will review the general subject of Yocto Project build and runtime dependencies. It will also introduce the many tools available to developers to investigate those dependencies (as computed by bitbake) to help resolve issues when those dependencies are either broken or confusing. Finally, there will be a live demonstration of these tools to help compare and contrast the information they provide, and to show how easy they can be to use. false Taskexp_cli (ncurses-based) Dependecies presentation Dependecies presentation PDF https://pretalx.com/yocto-project-summit-2022-05/talk/UN7JWM/ https://pretalx.com/yocto-project-summit-2022-05/talk/UN7JWM/feedback/ Kirkstone Talk 2022-05-18T18:10:00+00:00 18:10 00:30 `meta-riscv` is a OpenEmbedded / Yocto layer for RISC-V based boards and it contains a BSP for it. There aren't many boards on the market with RISC-V architecture but in 2021 SBC Nezha board with Allwinner D1 chip onboard was published and available to the market. It has basic support in mainline Linux kernel, U-Boot, and OpenSBI but also specific firmware eg. boot0 SPL, but mentioned RISC-V baseboard had no support in the Yocto Project. The presentation will show you the process of integrating a specific Nezha firmware into `meta-riscv`. The idea behind it was to spread the popularity of the Nezha board in the community. yocto-project-summit-2022-05-18555-support-of-the-nezha-allwinner-d1-in-meta-riscv /media/yocto-project-summit-2022-05/submissions/JZ39EH/nezha-board_TfYxCkC.jpg Cezary Sobczak en Nezha is a development board (SBC) that is designed by an AWOL. This project uses a D1 SoC from Allwinner which is used for the first time by the general public. Probably Nezha is the first massive produced and available SBC based on RISC-V architecture. It has a reference Linux system called Tina OS (based at OpenWRT) and other popular distros like Debian and Fedora, but for some unknown reason Nezha board didn't has support in a Yocto Project, but now it has. I would like to introduce to the community what the preparation of support in Yocto looked like, and what problems I had to face. At the moment, the support of specific software packages is at the development stage, hence the creation of appropriate recipes in Yocto will also facilitate the development process. I will focus on the introduction of the SBC and meta-riscv itself, machine configuration, prepared recipes for Linux kernel, U-Boot, OpenSBI, and boot0 SPL which are specific for this board and other specific configurations. In the end, you will see a working Yocto system running at the Nezha board. false Presentation in pdf format.

While this addresses many of the issues with dependency management and packaging at the source/build level, it causes issues when several core OE features are considered: reproducibility, licensing/SBOM, offline builds, sstate/hash equivalence, etc. There are also indirect issues such as CVE management, debugability, recipe transparency, code sharing, that are sources of maintenance challenges. The approach/implementation to solving these issues are largely language specific, but have the common themes of OE fetcher integration, dependency packaging (and reuse) versus per-recipe source code management, dependency specification, etc. Balancing reuse, build performance, scalability and other issues are also challenges that remain with the different solutions. Using golang as an example, this talk will cover these issues in more detail, and use meta-virtualization's go recipes as an example of one way to solve the problem. It will also summarize the issues with other languages and discuss what should be considered when doing an OE core fetcher implementation for a given language. yocto-project-summit-2022-05-18557-oecore-features-and-challenges-packaging-modern-languages Bruce Ashfield en This presentation is a survey of the modern languages and the problems they pose to OE core functionality.

TuxSuite uses TuxBake and Kas to do the builds in the cloud. TuxBake is an open source project from Linaro for doing reliable YP builds in a containerized environment. Kas is an open source project from Siemens for working with YP. TuxSuite YP builds use sstate caching and download caching to speed up the build process. TuxBake includes its own template definition, which makes it easy for users to define the many layers and configurations required for their custom YP build. The template allows developers to easily share their builds with others. The developers may easily replicate locally the build with containerized build environments. Tuxbake provides various OS distribution containers for developers to test their Yocto development on various Linux distros. TuxSuite forms the backbone for building kernels for LKFT Project(https://lkft.linaro.org/about/) and ClangbuiltLinux Project(https://github.com/ClangBuiltLinux/continuous-integration2).

These devices would be in operation for years without their software ever being touched again. But in today's connected world, users expect updates to be delivered to their devices in the field for a number of reasons, like new features, bug fixes, and security updates. The natural reaction for many software developers is to come up with a “quick and simple” solution for this requirement, often in the form of a homebrew shell script. Yet like most “it is just a couple of lines”-approaches, this creates massive technical debt, usually for the whole life cycle of the product in question. This should be avoided by proper planning early in the development process. By integrating Mender into the Yocto build pipeline, developers can free resources from maintaining custom solutions and use a robust mechanism for software distribution across the whole development and maintenance period. The end-to-end approach removes the need to learn and manage multiple components, and gives back time to the developers, helping them to do what they love: create good software. false Slides - preliminary https://pretalx.com/yocto-project-summit-2022-05/talk/J9NENV/ https://pretalx.com/yocto-project-summit-2022-05/talk/J9NENV/feedback/ Kirkstone Product Showcase 2022-05-19T13:30:00+00:00 13:30 00:30 Today's connected device fleets are getting larger and the ability to monitor individual devices within a fleet is required for troubleshooting, optimization, and general fleet maintenance.

We will also prepare a reference implementation in a Yocto layer that can be implemented in various Yocto setups, paired with a cloud-based fleet monitoring web interface. false Presentation Slides https://pretalx.com/yocto-project-summit-2022-05/talk/H93PRZ/ https://pretalx.com/yocto-project-summit-2022-05/talk/H93PRZ/feedback/ Kirkstone Product Showcase 2022-05-19T14:05:00+00:00 14:05 00:30 Wind River and the power of Yocto Project for commercial releases yocto-project-summit-2022-05-18421-wind-river-and-yocto-project Product Showcase /media/yocto-project-summit-2022-05/submissions/JW3ZVH/RGB_-_WNDRVR-Logo-Black-Teal_408mxow.png David ReynaJay Kruemcke en Wind River would like to share how adoption, compatibility, and contributions to Yocto Project has made strong product for their customers, and has also helped Wind River develop multiple strategic initiatives. false Commercial support for Yocto Project with Wind River Linux https://pretalx.com/yocto-project-summit-2022-05/talk/JW3ZVH/ https://pretalx.com/yocto-project-summit-2022-05/talk/JW3ZVH/feedback/ Kirkstone Product Showcase 2022-05-19T14:40:00+00:00 14:40 00:30 Oniro project is an Eclipse Foundation project which aims high at trying to unify production-targeted features across kernels and domains. We, at Huawei, as one of the main contributors to the project, want to provide our vision on how this approach can build on top of existing open-source projects to level up real integration of components, devices, products, brands, ecosystems, etc. yocto-project-summit-2022-05-18666-oniro-project-a-yocto-based-product-ready-distribution Product Showcase Andrei Gherzan en Oniro is currently focusing on the development of core components that we consider any IoT-based device should feature: cross-kernel support, system/application updates, opinionated security defaults, flexible development process etc. We do all that using Yocto/bitbake as the final layer of aggregation - the build system of choice in the project. With those horizontal functional aims, the project builds MVP (minimum viable products) verticals that can be seen as product blueprints. We actually call them “blueprints”, a way to showcase the capabilities of the platform and how an interested entity would be able to build its own production-ready use-case on top of Oniro. false Oniro Project - A Yocto-based product-ready distribution https://pretalx.com/yocto-project-summit-2022-05/talk/FCQDYV/ https://pretalx.com/yocto-project-summit-2022-05/talk/FCQDYV/feedback/ Kirkstone Talk 2022-05-19T15:25:00+00:00 15:25 00:30 This talk will provide an update and status of the changes made to Kirkstone regarding changing variables, functions and files to use more inclusive language.

Recently the class has gained a new JSON-based output format and a possibility to report recipes without any known security issues. The Eclipse Oniro project team has also worked on fixing issues when running a 'world' build when using multiple layers. In this talk, Marta is going to explain reasons behind those features and how you can benefit from them. She will also describe issues the team encountered and their solutions. yocto-project-summit-2022-05-18442-cve-checking-an-entire-distribution Marta RYBCZYNSKA, Ygreky en Yocto/OpenEmbedded offers a possibility to check for known security vulnerabilities (CVEs, https://www.cve.org/) in a given image or configuration. The core of the functionality is the cve-check class, which functions verifies a package version against the data in the National Vulnerability Database (NVD, https://nvd.nist.gov/). Until recently, the only output format has been a text file. While easy to understand for a human, it is not designed for machine processing. The recent work has been to add another, JSON-based output, while keeping the old one for compatibility reasons. The new format allows easy machine processing, generation of statistics and the like. The talk will include: the introduction of the cve-check, descriptions of the text and JSON output formats, example tools for post-processing and various lessons learned while enabling a CVE-check for a complete Eclipse Oniro distribution. false Presentation slides https://pretalx.com/yocto-project-summit-2022-05/talk/KPHFNE/ https://pretalx.com/yocto-project-summit-2022-05/talk/KPHFNE/feedback/ Kirkstone Talk 2022-05-19T16:35:00+00:00 16:35 00:30 Upstream Python has deprecated ‘distulils’ and is moving towards ‘pyproject.toml’ instead of ‘setup.py’. In this talk you will learn what changed in the Yocto Project classes and recipes for Python packages in the 4.0 ‘kirkstone’ release. You will also learn about how to look at an upstream ‘pyproject.toml’ and determine which of the new classes to use instead of ‘setuptools3’. We will also discuss recipes for packages that add Rust extensions for Python. yocto-project-summit-2022-05-18397-where-did-my-setup-py-go-changes-in-python-recipes-in-yocto-project-4-0-kirkstone-release /media/yocto-project-summit-2022-05/submissions/3KCYHQ/yocto-python_J71f1Bp.png Tim OrlingRoss Burton en Upstream never stops moving and we need to ride the wave of change. With the deprecation of ‘distutils’ in Python 3.10 (slated for removal in Python 3.12), we need to understand how to use ‘setuptools’ instead. As if that wasn’t enough, with the implementation of PEP-517 and related changes comes the new ‘pyproject.toml’ standard as a replacement for ‘setup.py’. Python packages are no longer distributed as “eggs”, but are now only distributed as ‘sdist’ (source tarball) or ‘wheel’ (installable packages). Meanwhile C-extensions are not the only kid in town, Rust extensions are beginning to be implemented, such as in ‘python3-cryptography’, Hold onto your seats while we take a quick tour of the new world of Python recipes in Yocto Project! false YPS Python Changes Slides (PDF) https://pretalx.com/yocto-project-summit-2022-05/talk/3KCYHQ/ https://pretalx.com/yocto-project-summit-2022-05/talk/3KCYHQ/feedback/ Kirkstone Lightning Talk 2022-05-19T17:35:00+00:00 17:35 00:15 In this talk we will discuss how sstate-cache works and in which scenarios it shines.

There is also an effort to create and support a reference package feed as part of the outputs of the project. This presentation will introduce the components that underpin package capabilities, and show how they work together to enable workflows based on binary artifacts. Package feed extension, and target update will be discussed, as well as how containers can be used in a 'docker build' like manner to package and deploy applications. It will then give an overview and status update on the "5 Year" planning and binary distribution effort. Distinctions between core project capabilities, and what can be leveraged from the wider ecosystem will also be discussed as part of this presentation. yocto-project-summit-2022-05-18556-the-yocto-project-reference-binary-distro-effort Bruce Ashfield en This presentation is an overview of the various workflows and components that make up a modern package/container based distribution.
