by Sebastian Sumpf 03 Nov '25

03 Nov '25

We are happy to announce the CfP for the "Microkernel and Component-Based OS" devroom at the upcoming FOSDEM 2026. Developers and users of various free and open-source microkernel-based and component-based operating systems will meet again at FOSDEM during the weekend of January 31st and February 1st 2026 and will share a developer room. The Microkernel and Component-Based OS devroom is currently looking for your participation in the form of proposals for talks, demos and other related activities. Possible topics for the devroom include, but are not limited to: * Introduction of a specific OS or framework * Design of subsystems and the general architecture of an OS * Languages, tools and toolchains used * Enabling support for hardware architectures, devices and programming languages * Development processes, debugging * Maintenance, testing and release engineering * Safety, security and robustness * Trends and challenges * Research and open questions * Community and governance * Use cases, experiences and status updates * Best practices and lessons learned * Live demos Important Dates The deadline for submitting proposals is December 1, 2025 (23:55 CET). Please use the FOSDEM website at https://fosdem.org/submit, select the track "Microkernel and Component-Based OS" and include at least the following information: * Title of your proposal * Short abstract (one or two paragraphs) * Duration (20 - 30 minutes, including demos and Q&A) * Your full name * Your short bio The devroom schedule (with accepted talks) will be announced on the devroom website at https://fosdem.org/2026/schedule/track/microkernel by December 15, 2025. The schedule will also be posted to the devroom mailing list and the speakers will be notified via email. Like previous years, the devroom will take place as an in-person event at the ULB Campus Solbosch in Brussels, Belgium during the second half of February 1, 2026 (Sunday). Due to the high number of submissions that FOSDEM received again this year, our devroom has only been allocated half a day. Therefore, the final decision on the duration of the talks will be made by the devroom organizers based on the number of accepted proposals. Given these restrictions, eight to nine half hour slots with a speaking time of 20 to 25 minutes and 5 to 10 minutes of Q&A form the upper limit. Requirements The communication language of the devroom is English. All content must relate to free and open-source software. By participating in the event, you agree to the publication of your talk recordings, slides and other content provided under the same CC-BY license as all other FOSDEM content. All participants are expected to adhere to the Code of Conduct: https://fosdem.org/2026/practical/conduct/ Contact For the 2026 edition, the organizers of the devroom are * Sebastian Sumpf (sebastian.sumpf [at] genode-labs.com) * Josef Söntgen (josef.soentgen [at] genode-labs.com) For any comments, questions and suggestions, please do not hesitate to contact us directly or via microkernel-devroom-manager at fosdem.org. Announcements and inquiries are additionally available through the devroom mailing list https://lists.fosdem.org/listinfo/microkernel-devroom About the Devroom Since the first Microkernel OS Devroom at FOSDEM 2012, this devroom has been a part of each subsequent FOSDEM (with slight variations of the name). The focus gradually widened to include component-based and other operating systems. It has now become somewhat of a tradition for the open-source operating systems community, a kind of "extended family meeting" and it is one of the very few places where microkernel and operating-system enthusiasts meet regularly. To date, over two dozen projects have participated in one way or another. Many of the projects face similar challenges but come up with partially different solutions. Therefore, the goal of the devroom is to bring the various projects together, let them exchange ideas, cross-pollinate and socialize. As in the past, the devroom will offer the stage both to established community members and to newcomers. Our goal is to select talks in an inclusive manner and to create a balanced and unbiased schedule, while keeping the quality of the devroom as high as in previous years. About FOSDEM FOSDEM is a two-day conference organized by volunteers to promote the widespread use of free and open-source software. FOSDEM is widely recognized as one of the largest and best such events worldwide. FOSDEM covers a wide spectrum of free and open-source software and hardware projects and offers a platform for people to collaborate. To this end, FOSDEM has set up developer rooms (devrooms) where teams can meet and showcase their projects. Devrooms are a place for teams to discuss, hack and publicly present new ideas, latest results, lightning talks, news and proposals. Besides developer rooms, FOSDEM also offers main tracks, lightning talks, certification exams and project stands. In recent years, FOSDEM has been hosting more than 5000 developers annually at the ULB Solbosch Campus in Brussels, Belgium. The participation in FOSDEM is totally free and requires no registration, although the organizers gratefully accept donations and sponsorship. Devroom Dinner Over the years, it has become a tradition that devroom speakers and enthusiasts meet for dinner somewhere in Brussels after the event to continue discussions, socialize and meet old and new friends. We plan to follow that tradition in some form as well in 2026 and will inform you about the exact arrangements later. Hope to see all of you in Brussels!
