Feedback from Embedded Recipes 2026

Group picture of all Bootlin attendees For the fifth time, the Bootlin team attended the Embedded Recipes conference to meet and share with the embedded community. This year, like last year, it was in the beautiful city of Nice. We were also proud to be a Chef Sponsor of the event.

Participation from Bootlin was again strong, with no less than 19 engineers attending: Alexandre Belloni, Antonin Godard, Benjamin Robin, Benoit Monin, Hervé Codina, Jérémie Dautheribes, João Marcos Costa, Köry Maincent, Louis Chauvet, Luca Ceresoli, Mathieu Dubois-Briand, Miguel Gazquez, Paul Louvel, Richard Genoud, Romain Gantois, Théo Lebrun, Thomas Bonnefille, Thomas Petazzoni, Thomas Richard.

As usual, here is a blog post with summaries of a few talks. You can find the full schedule here, and video recordings are now available for day 1 and day 2.

Display Next Hackfest 2026

From May 29 to May 31, 2026, the Linux Display Next Hackfest convened in the vibrant city of Nice, France, just after Embedded Recipes 2026. This time the event was hosted by Collabora. This annual gathering has established itself as a cornerstone event for the Linux Graphics community, bringing together a dynamic mix of kernel developers, compositor maintainers and hardware vendor to push the boundaries of Linux Graphics innovation.

For the third consecutive year, Bootlin was proud to participate, this time with a team of three: Köry Maincent, Luca Ceresoli, and Louis Chauvet. Our involvement in this event is more than just attendance, that’s a way to build a bridge between our customers needs and the Linux community.

This year’s Hackfest was particularly rich in discussions, covering a broad spectrum of topics such as MST bandwidth allocation, Native DisplayID, tiled monitors, color operations, Variable Refresh Rate, and High Dynamic Range. We presented four critical areas for which we aim at bringing improved upstream support, to meet the needs of our customers:

Link training and firmware update issues on DisplayPort
DRM bridge hotplug support
Backlight configuration
DisplayPort status properties

Back from Display Next Hackfest 2025

This year, the Linux Display Next Hackfest was hosted by AMD in Toronto. The event brought together a diverse group of contributors from a wide range of projects and companies, all united by a shared interest in advancing Linux Graphics. Participants included kernel developers, compositor maintainers, hardware vendors, and others deeply involved in the graphics stack. For the second year in a row, I had the opportunity to attend in person—an important step for Bootlin, as staying closely engaged with the latest developments in the Linux Graphics Stack is key to delivering upstream-friendly, cutting-edge support for our customers.

As usual, a wide range of topics were discussed: commit failure feedback, backlight API, adaptive backlight management, testing, pageflip, scheduling, variable refresh rate (VRR), atomic commits, and others. What made this edition especially noteworthy was the presence of two color experts: a full day was dedicated to exploring HDR—what it is, how it works, and how we can support it properly in Linux.

You can read the notes for this event on Harry’s blog, or from Xaver Hugl, more will probably be posted later by other participants.
