Bootlin engineer Louis Chauvet talks at XDC 2025 in Vienna

XDC 2025The X.Org Developer’s Conference (XDC) is the key annual event for developers shaping the future of Open Graphics technologies, including the Linux kernel, Mesa, DRM, Wayland, and X11. It is taking place on Sep 29, Sep 30 and Oct 1 in Vienna, Austria.

Bootlin engineer and Linux graphics specialist Louis Chauvet will be attending and giving a talk on Display Testing without Hardware: Discovering the Power of VKMS!. In this session, he will introduce VKMS, demonstrate its testing capabilities with real examples, and share details on the new features that Bootlin is actively driving upstream.

After participating in the Display Next Hackfest earlier this year, this second graphics-focused event confirms Bootlin’s involvement in the Linux graphics ecosystem. It reflects our commitment not only to staying at the cutting edge of graphics technologies, but also to contributing improvements that benefit the entire community.

If your projects involve Linux graphics and you are looking for expertise, feel free to get in touch with us to see how Bootlin can help.

Welcome to Benoît Monin and Benjamin Robin!

We’re very happy to welcome in our team Benoît Monin and Benjamin Robin.

Benoît MoninIt’s been a few months already that Benoît Monin joined our team, as he started in May, just in time to participate to our yearly company-wide team week event in June. Benoît graduated from CPE Lyon in 2002, and then spent no less than 21 years at Centum Adeneo, where he worked on a large number of embedded projects, mostly Linux-based. He supported Alstom Transport on embedded systems used in train communication and signaling, including Linux porting, hardware integration on ARM platforms, and R&D on 5G train-to-ground communication. His past experience also includes work for Airbus on measurement and noise analysis systems, and for JDSU on high-speed communication test equipment using PowerPC. Benoît is also a contributor to open-source, as he contributes to OpenStreetMap and the openSUSE project. Since his arrival at Bootlin, Benoît has been mostly focused on Linux kernel upstream work, mainly around the Mobileye platforms. Check out Benoît’s page on bootlin.com for more details.

Benjamin RobinMore recently, in late August, Benjamin Robin also joined our team. This time, he joined just in time to participate to the recent Open Source Summit Europe in Amsterdam, a great opportunity to meet almost the entire Bootlin’s team, and also the embedded Linux community. Benjamin also graduated from CPE Lyon, but in 2011. Prior to joining Bootlin, Benjamin spent 14 years at Centum T&S, where he held roles as both an embedded software engineer and an embedded Linux engineer. Benjamin has primarily worked on ARM platforms for industrial customers, always with a strong focus on low-level development close to the hardware. His expertise spans from embedded Linux system development to critical bare-metal software on constrained platforms such as ARM Cortex-M. He has developed significant expertise in building custom BSP layers using Yocto for projects involving various frameworks, including Qt. Benjamin also has experience developing Linux drivers for customer-specific hardware. His platform experience covers a wide spectrum, from Xilinx Zynq 7000, OMAP, and TI Sitara processors, to i.MX SoCs, Marvell OCTEON SoCs, and even some experience with x86-based SoCs. Beyond his professional work, Benjamin contributes to various open source projects, fixing bugs and implementing enhancements to improve functionality. He for example actively supports the French-speaking Arch Linux community. Check out Benjamin’s page on bootlin.com for more details.

We are pleased to welcome Benoît and Benjamin to our Oullins office near Lyon. Their arrival brings the Lyon team to 12 members, now equaling the headcount of our Toulouse office.

Bootlin engineer Louis Chauvet at the 2025 Display Next Hackfest

Like last year, Bootlin engineer Louis Chauvet is attending the 2025 Display Next Hackfest, taking place this week in Toronto, Canada, and hosted by AMD.

As described on the event website:

The Display Next Hackfest is an event where talented developers will gather to explore the latest technologies and trends in the Linux Display Stack. 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, backlight control, testing and CI, etc.

Attending this hackfest is especially important for Bootlin, as it allows us to stay actively involved in the upstream Linux graphics ecosystem. By participating in discussions and collaborative problem-solving sessions with key contributors and maintainers, we ensure that our expertise remains aligned with the latest developments and best practices. This also strengthens our ability to support our customers with state-of-the-art display integration and driver development, while contributing improvements and fixes back to the community.

Materials for our “Embedded Linux Networking” training released

Bootlin Embedded Linux networking trainingBack in April 2025, we announced the launch of a brand new training course titled Embedded Linux Networking. At the time, the course was still under active development, and training materials were not yet available.

Since then, Bootlin engineer and networking expert Maxime Chevallier has finalized the course and successfully delivered it to our launch customer in the US, receiving excellent participant feedback. With this first session completed, and in line with our long-standing commitment to open-source education, we are pleased to release the complete training materials under the Creative Commons BY-SA license:

Here are a few highlights from participant feedback on the first session:

The amount of information shared was incredible.

Maxime’s knowledge of the subject is outstanding. He presented the material fluently without simply reading from the slides. His English was excellent, and the content was clearly communicated.

Maxime demonstrated deep expertise and answered every question thoroughly. His passion for the topic was evident throughout.

Thank you for the training; it was very well done.

If you’re interested in joining this training, we offer several options:

We hope these freely available materials, along with the training itself, will be valuable resources for engineers tackling networking challenges in their Embedded Linux projects.

Linux 6.15 released, Bootlin contributions inside

Penguin coding, AI generatedLinux 6.15 has been released last Sunday, and we as usual encourage our readers to look at the LWN summaries of the merge window (part 1, part 2) for a good summary. CNX-Software also has a summary more oriented towards hardware support for ARM and RISC-V platforms.

On our side, we have been quite active in this release cycle, with no less than 145 commits from Bootlin engineers merged. Also, our engineers who maintain various subsystems in the Linux kernel reviewed and merged a total of 104 patches from other contributors.
