Linux 6.10 released, Bootlin contributions inside

Linux 6.10 was released last Sunday, following its now well-known release cadence. As usual, head over to LWN.net to have some good summary of the important features merged in this kernel release: part 1 and part 2.

LWN also published an article on statistics of the 6.10 release cycle, and Bootlin shows up in the most active employers by changed lines, with 7746 lines changed by Bootlin engineers. According to ths Kernel Patch Statistics site, we contributed 110 changes, putting us as the 19th contributing company (counting “Unknown” and “Hobbyists” as companies).

Also, in addition to the 110 patches we contributed, some of our engineers are also maintainers of different subsystems, and as such they review/merge patches contributed by others:

  • Alexandre Belloni reviewed/merged 19 patches for the I3C and RTC subsystems which he maintains
  • Grégory Clement reviewed/merged 14 patches for the Marvell ARM and ARM64 platforms that he maintains
  • Miquèl Raynal reviewed/merged 12 patches for the MTD subsystem, which he co-maintains

Bootlin at Open Source Summit Europe and Linux Plumbers in Vienna, Sep 16-20

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 2024

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.

Linux Plumbers 2024Right 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!

Bootlin releases OpenWrt support for STM32MP1 platforms

OpenWrt logoA 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.

Back from the Embededded Linux Conference: selection of talks #1

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.

Bootlin engineer Louis Chauvet at Linux Display hackfest

2024 Display Next HackfestFrom 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.

Yocto 5.0 Scarthgap released, Bootlin contributions inside

Yocto Project SummitThe latest release of the Yocto Project, version 5.0, code named Scarthgap has been published a few days ago. The release notes provide the best summary of what’s new in this release. Being a Long Term Support (LTS) release, it will be maintained during 4 years with bug fixes and security updates, which makes this release particularly important for a large number of embedded Linux projects and products.

At Bootlin, we are using Yocto for a large fraction of the Linux Board Support Packages that we develop, maintain and upgrade for our customers. But we’re not only users of Yocto: we’re also contributors and maintainers. In this blog post, we’ll highlight our contributions to this release, which take various forms.
