Our resulting images, called balenaOS, include a container runtime and some tooling to connect to balenaCloud, allowing for remote management of the devices. Keeping up with just one BSP layer is hard enough, let alone the many Arm SoC families and their corresponding BSP layers that our customers make use of. Let’s talk about our use-case, the process we use to build and version these OS’es, chat about some challenges we face, and gather feedback from the community to improve the overall experience. yocto-project-summit-2021-10160-yocto-at-balena-building-70-unique-os-es-for-iot-devices Intermediate Track David Tischler en 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. false Slide Deck https://pretalx.com/yocto-project-summit-2021/talk/NALT3Q/ https://pretalx.com/yocto-project-summit-2021/talk/NALT3Q/feedback/ Presentation Room Talk 2021-05-25T12:50:00+00:00 12:50 00:30 OpenWrt is an open source project for Linux-based operating systems, mainly used on embedded devices to direct network traffic. Its development environment and build system, known together as OpenWrt Buildroot, are based on a heavily modified Buildroot system. However, it is possible to prepare an OpenWrt system using the Yocto Project and meta-openwrt. In my presentation, I would like to provide an overview of this layer. yocto-project-summit-2021-10214-building-openwrt-with-the-yocto-project Intermediate Track Tomasz Żyjewski en 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.

At its core, is a Git-like content-addressed object store with branches (or "refs") to track complete filesystem trees. And one of its big advantages is on implementing an update system, since it provides transactional (atomic) and delta-based upgrades with rollback support. It has been used in modern package management systems like Flatpak and rpm-ostree, and Linux distributions like Apertis, Endless OS, Fedora CoreOS/Silverblue/IoT and GNOME OS. In this talk, we will dig deeper into how OSTree works, taking a hands-on approach to learn how to designing an OSTree based embedded Linux systems using the meta-updater layer. yocto-project-summit-2021-10142-designing-ostree-based-embedded-linux-systems-with-the-yocto-project Intermediate Track Sergio Prado en In this talk, I will cover: 1.

It aims to provide convenient and portable interfaces to hardware security in the programming language of your choice. Parsec is being integrated into the meta-security layer of Yocto Project. This is an opportunity to learn more about Parsec and the value it can bring to your Yocto-based deployment. yocto-project-summit-2021-10121-parsec-the-platform-abstraction-for-security Intermediate Track /media/yocto-project-summit-2021/submissions/3L3HGT/ARM1007_PARSEC_Logo_ST2_RGB_Stacked_Colour_zfZF4GP.png Paul HowardAnton Antonov en 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 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. false Slides https://pretalx.com/yocto-project-summit-2021/talk/PRYUYZ/ https://pretalx.com/yocto-project-summit-2021/talk/PRYUYZ/feedback/ Presentation Room Talk 2021-05-26T18:45:00+00:00 18:45 00:30 An overview of Gitlab CI and a number of different ways it can be used for building and testing layers in Yocto Project/OpenEmbedded yocto-project-summit-2021-10163-gitlab-ci-for-dummies Intermediate Track Jon MasonBruce Ashfield en 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. false slides https://pretalx.com/yocto-project-summit-2021/talk/XHZQRT/ https://pretalx.com/yocto-project-summit-2021/talk/XHZQRT/feedback/ Presentation Room Talk 2021-05-26T19:20:00+00:00 19:20 00:30 The linux-yocto reference kernel is part of OE core and provides a stable and tested set of targets (simulated and hardware) as part of each release. This talk will discuss why the reference kernel is important (even in an environment of many vendor, board and custom kernels) and what it provides to the project. Additionally, the tooling and workflows that have been developed since the reference was first introduced will be presented. Specific attention will be paid to how both production builds and development/extension of the kernel are supported. How the tooling eases maintenance and security of 6 architectures over 12+ BSPs and multiple releases will be illustrated through examples and workflow descriptions. Finally, Kernel configuration management and auditing will be covered as a topic as part of workflow discussions and how they can be used across many kernels/versions and for developing consistent/new BSPs. yocto-project-summit-2021-10193-linux-yocto-reference-kernel-maintenance-and-kernel-workflows Intermediate Track Bruce Ashfield en 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. false session slides https://pretalx.com/yocto-project-summit-2021/talk/NYYGMV/ https://pretalx.com/yocto-project-summit-2021/talk/NYYGMV/feedback/ Presentation Room Talk 2021-05-26T19:55:00+00:00 19:55 00:05 It's wrap! yocto-project-summit-2021-10296-closing-talk All Attendees Trevor Woerner en It's wrap! false https://pretalx.com/yocto-project-summit-2021/talk/SDBQRE/ https://pretalx.com/yocto-project-summit-2021/talk/SDBQRE/feedback/
