This post is our third blog post in our series about Zephyr. You can check our previous episodes: Getting started with Zephyr and Understanding Zephyr’s Blinky Sample. In this third blog post, we will see how to implement a device driver for Zephyr, from the configuration of the build system, the code of the driver itself, to contributing the driver upstream.

On the week of September 16-20, Vienna is going the place to be for all open-source developers, with a large number of conferences taking place during this week. Being strong contributors to several key open-source projects, Bootlin will be strongly present at those conferences.
Open Source Summit Europe will take place on Sep 16-18, and its schedule has recently been published. This year, the Embedded Linux Conference part of this conference is unfortunately reduced to just 2 tracks of 2 days, but we nevertheless hope to see some interesting topics. Bootlin has contributed and will contribute to this event with:
In addition, no less than 12 Bootlin engineers will participate to this Open Source Summit Europe: Alexandre Belloni, Grégory Clement, Hervé Codina, João Marcos Costa, Kamel Bouhara, Louis Chauvet, Miquèl Raynal, Richard Genoud, Théo Lebrun, Thomas Petazzoni, Thomas Perrot and another engineer who will join our team just in time before the event to be part of the trip.
Right after the Open Source Summit, we will also be present at the Linux Plumbers conference. We have already submitted a few topics in various micro-conferences, and we’re hoping to see them accepted. Regardless of that, 8 engineers from our team will be attending Linux Plumbers: Hervé Codina, Louis Chauvet, Luca Ceresoli, Maxime Chevallier, Miquèl Raynal, Théo Lebrun, Thomas Petazzoni, Thomas Perrot.
We look forward to meeting the community, presenting our projects and ideas and learning about the work done by others! See you all in Vienna in September!
A few years ago, as part of its collaboration with ST, Bootlin developed and released buildroot-external-st, a project offering the integration of the support for ST’s STM32MP1 platform with the popular Buildroot build system, as an alternative to the Yocto Project offering provided directly by ST.
Today, Bootlin is happy to announce the openwrt-feed-st project, which in a similar way, provides integration of ST’s STM32MP1 platforms with the OpenWrt build system. This work was done by Bootlin’s OpenWrt expert Thomas Richard.

After our initial blog post on Zephyr in which we discovered how to download, build and flash Zephyr on two different boards, in this second blog post, we will dive into the code of Zephyr to understand how exactly the Blinky example works. To illustrate this, we will use the same boards as in our last blog post: an Arduino Nano 33 BLE, and a STM32L562E-DK.
We will first look at how the example application determines which LED to blink and where it’s plugged in, and then we will look at the code responsible for blinking the LED.
After a first and a second episode, our series of blog posts with our selection of talks we liked at the latest Embedded Linux Conference continues. Read on to discover the last 3 talks that we enjoyed and decided to summarize and highlight for you.

The Linux Display Next Hackfest, graciously hosted by Igalia in the beautiful city of A Coruña, was an event that brought together a diverse group of individuals from various projects and companies, all with a common interest in the world of Linux graphics.
The event was a buzzing hive of discussions, with the primary focus being on Direct Rendering Manager (DRM), compositors and an array of topics related to graphics in Linux. Representatives from Fedora, Mutter, KWin, AMD, Nvidia, Google, and many others were present, lending their expertise and insights to the conversations.

As we wrote in a previous blog post, 11 engineers from Bootlin attended the Embedded Linux Conference in Seattle in April. We have a tradition after such an event to share with you a selection of talks that we have found useful. In order to achieve this, we ask each of our engineers who participated to the conference to pick one talk they would like to highlight, and write a short summary/feedback about the talk. In this first installment of this series of blog posts, we’ll share our selection of 4 first talks.

Linux 6.9 was released last Sunday, and as usual we refer our readers to the excellent LWN.net coverage of the Linux 6.9 merge window (part 1 and part 2) to get a good overall picture of the improvements and new features brought by this release.
On our side, we contributed a total of 119 commits authored by Bootlin engineers, but we also merged a total of 95 patches from other contributors, as several Bootlin engineers as also maintainers of various drivers/subsystems in the Linux kernel.

From May 14 to May 16, Igalia is organizing the 2024 Display Next Hackfest, an event where talented developers will gather to explore the latest technologies and trends in the Linux Display Stack.
As explained on the event website:
It has an unconference format where participants propose topics for presenting, roadmapping, discussing and examining together. It aims to unblock bottlenecks, design solutions, raise pitfalls and accommodate the needs of each layer of the display stack. Participants should feel free to propose any topic which interests them. Some topics from the previous edition include: HDR and color management, frame timing and variable refresh rate (VRR), atomic flips, testing and CI, etc.
Bootlin engineer Louis Chauvet, who has started contributing to the Linux kernel VKMS driver, and is starting to work on IGT and the latest version of the Chamelium CI testing hardware, will participate to this hackfest, together with many developers from Igalia, Redhat, Intel, Google, RaspberryPi, AMD, ARM, Collabora and more. This will allow us to discuss current developments and topics, and meet the relevant developers of the Linux graphics/display community.
