Yocto at Balena: Building ~70 Unique OS’es for IoT Devices

The Yocto Project enables us at balena to (relatively) easily build support for about 70 or so single board computers and small devices, intended to be used as IoT endpoints running containerized workloads. The resulting output of our build is called balenaOS, and it is of course a minimal linux distribution, targeting devices such as the Raspberry Pi series, Beagleboards, Jetson products, Intel NUC’s, and other similar systems. In the spirit of Yocto, balenaOS is also open source, and there is a community of developers who contribute board support, patches, fixes, etc. This session is intended to be a dialogue and conversation. I’ll cover the use-case, process, and challenges we face, but I am also very interested in getting to know the community better, fielding questions, soliciting feedback, and gathering ideas on how to improve our outcomes.

Building OpenWrt with the Yocto Project

The purpose of this presentation is to show how to prepare an OpenWrt system with Yocto. In the beginning, the build system dedicated to OpenWrt - OpenWrt Buildroot will be briefly described. Then, a thorough analysis of the meta-openwrt layer will be performed. In addition to the functionalities it provides, it will also describe open issues and the level of compatibility with the current OpenWrt release. The presentation will end with a short useful demo, consisting of launching the OpenWrt system built with the use of meta-openwrt on the Raspberry Pi 4 platform.

Demystifying the OVERRIDES mechanism and Bitbake operators

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.

Multiconfig is a power feature of bitbake that allows multiple distinct configurations to be defined and built simultaneously. In this hands-on, you will implement some multiconfig examples to learn some of the ways it can be used to create complex systems.

Parsec - The Platform Abstraction For Security

More and more compute workloads are migrating from the cloud to the edge, where they can be executed in closer proximity to sensor devices, avoiding expensive backhaul of data volumes to the cloud. Developers are used to deploying workloads with cloud-native tools and technologies, where APIs are portable and decoupled from physical platform details. But the threat landscape of edge computing is different from that of the cloud. It demands hardware security protection for private assets such as keys. A variety of hardware security solutions exist in the highly-diverse ecosystem of the edge. Using these requires knowledge of specialised APIs, which can be difficult to consume, and are not always portable. Parsec creates abstractions for hardware security, providing interfaces that are portable, and creating ergonomic developer experiences in multiple programming languages. This year, Parsec recipes are being added to the meta-security Yocto layer, making it possible for developers and systems integrators to gain the advantages of Parsec in their Yocto-based deployments. In this talk, we present a high-level overview of the Parsec project. We will describe its architecture and talk about the project status and roadmap. We will also talk about our experiences of integrating this Rust-based security project into the meta-security layer.

Surfing on an Interactive Kiosk

The Yocto Project and OpenEmbedded are often used for building custom GNU/Linux distributions for powering interactive kiosk and displaying HTML5 content. Although Chromium is the most popular choice for a web browser, it is infamous for the long build time. In this presentation you will see a practical alternative approach using the surf web browser. Surf is a simple minimalist web browser based on WebKit2/GTK+ with interface that does not include any graphical control elements. It a perfect fit for a kiosk. The presentation will offer the exact steps how to build a minimal GNU/Linux distribution with systemd, X11, openbox window manager and the Surf web browser. Furthermore, we will discuss practical examples for software over air updates of this simple distribution. Raspberry Pi 4 will be used as a reference hardware for all demonstrations. This presentation is suitable for beginners. It will demonstrate a practical use of the Yocto Project/OpenEmbedded for a common use case, some tips and tricks as well as examples for selection systemd as init system and software over the air mechanism.

Using rust with bitbake and meta-rust

This session will discuss using the Rust programming language in Yocto-based projects. We will cover how to enable Rust cross-compiler infrastructure using meta-rust. By the end of the session participants will have information on building a Rust-based application with bitbake. We will also cover the advantages of using Rust and how it compares to other modern programming languages. Participants will be equipped to know where Rust will be most effective and what trade-off exist in its use. The ideal audience is anyone who is curious about the Rust programming language, or new languages in general, with some familiarity of the Yocto project. Assumes no existing knowledge about Rust.

Runtime Package Management: When, Why & How

Runtime package management is a controversial topic in the embedded Linux community. It is a known attack vector for hijacking consumer devices and can result in inconsistent states or even bricking when relied on for OTA updates. We will look at what conveniences runtime package management offers software development teams and which stages of the product development cycle does it make the most sense.

Case Study: Yocto / OpenEmbedded in All Scenarios OS

We are about six months in from kicking off All Scenarios OS (former OpenHarmony), and Yocto/OpenEmbedded was a core building block from the start. We consider today to be an excellent time to sit down and look at what we are currently using and our plans for the future. The project aims at unifying various OS, BSP and software stacks layers under the same ecosystem dealing with interoperability and scalability. On the Linux side, working on a poky-based distro, using dunfell for the build meta-data layers is a pretty typical setup. The more exciting parts will be using musl as the libc provider and llvm as the default toolchain. Besides the building infrastructure for Linux, we also do it for Zephyr and FreeRTOS through their relevant layers. In our CI system, we run every merge request through an IP compliance toolchain which feeds back into our needs for the included layers and recipes. That puts governance in a central position as part of our development cycles. When starting this journey, we had a broad range of experiences, from not exposed to Yocto/OE to being a very experienced layer maintainer. Combining the project's bring-up feedback with some of the more unique requirements will result in a list of topics we want to discuss in the second part of the presentation. Hopefully, these topics will provide helpful feedback for the project by unwrapping the pain points we stumbled on.

While the Yocto Project has the autobuilder, individual layers do not have access to this. With Gitlab CI, corporations and individual developers have the ability to have something similar. In this session, we will go into detail about the individual parts of a Gitlab CI configuration, how some users are using it, and how an individual might set it up and run it for their own layer.

This presentation can be considered "a week in the life of kernel maintenance". It's goals are to uncover the how/when/why things are done as they are, and to shed light on some of the tooling and techniques that are used to maintain kernels at scale. It will also show how the existing infrastructure and tooling can be used to develop new BSPs and share/leverage knowledge of other developers. It will be suitable for the begginer user and integrator. Experienced kernel developers with their own workflows may also be interested.
