Hands-On Kernel Lab: Introduction to linux-yocto, kernel config fragments and common workflow patterns

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.

Bitbake 101, running the Yocto Project workflow

What does Bitbake do, what are Bitbake's job responsibilities, and how does Bitbake achieve what it does? Keeping the basics in mind can improve the work experience a lot since it will help avoid working against a black box. In this talk we take a look at what we feed into Bitbake's generic task execution engine, and explore together the way source-code takes when it gets transformed into packages and binaries for your Yocto Linux distribution.

Quentin will first talk about :append, :remove, +=, ?= and other operators, with the hope of shedding light on some surprising behaviors, in which context they should be used and how they differ from each other. Then, the OVERRIDES mechanism will be on the menu, with the different scenario it can be used in and some important gotchas will be presented. A couple of hints will also be given to debug variables. Quentin will present the topic from the perspective of a Yocto user. This is an update of a talk given at Yocto Project Summit 2021.05, with new override syntax and some corrections.

Breaking down the BitBake build on the process level

In this talk we will discuss detailed analysis of the Yocto build on the resource-per-tool level. Understanding where the time goes in a build and what are the bottlenecks in your implementation can help with choosing the right sizing for your build machine or build grid. Using the example of an Automotive Grade Linux build, We will analyze actual CPU time spent on compiling, packaging and performing other common tasks, gaining insights on what makes builds take as much as they do, which build-time resource constraints exist, and how they could be alleviated.

Yocto Layer CI Build and Test with GitHub Actions

I've been maintaining meta-mono for some years now. 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.

Survey of 3rd party Yocto tooling

The Yocto project provides excellent tooling for building Embedded Linux distributions; however many users have found a need to extended the project with extra tooling to achieve specific goals related to the build environment setup, additional layer management, and build configuration management. Many of these tools have been developed by various parties over the years, and Joshua will attempt to impartially describe some of the options available to you, what they do, and why you many want to use them in your setup. Tools covered will include: combo-layer, git submodules, git subtrees, crops, pyrex, whisk, kas, and others TBD.

YP Dependency Issues: Tools and Techniques

Dependency issues in bitbake builds can be rare, but when they happen you need tools that are easy to access and use to resolve those issues quickly, especially when the problem appears to be a needle in a haystack. 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.

Support of the Nezha Allwinner D1 in meta-riscv.

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.

Building Yocto Project at scale with TuxSuite

TuxSuite can run thousands of builds in parallel, allowing for faster build validation across a variety of Yocto Project build settings, depending on the user's needs. 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). Every day, TuxSuite receives roughly 8000 requests for Linux Kernel builds. TuxSuite also has an API endpoint for testing Linux kernels on Qemu for multiple architectures. These success stories fueled TuxSuite's decision to add support for building YP.

Showcase - Mender, an end-to-end OTA solution for Yocto

In traditional software development for embedded devices, compiling and handing the resulting artifact off to manufacturing was the final step. 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.

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.

CVE checking an entire distribution

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.

Where did my setup.py go? Changes in Python Recipes in Yocto Project 4.0 ‘kirkstone’ Release

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!
