Also available at https://discourse.llvm.org/t/fosdem-2027-llvm-devroom-call-for-presentations... We are pleased to announce that LLVM will once again have a devroom at FOSDEM, which takes place on 30 & 31 January 2027 in Brussels, Belgium. The room is tentatively scheduled for the Sunday morning session, but this could change. Additionally, this year there will also be a room dedicated to MLIR. As possibly the largest European Open Source conference, FOSDEM attracts more than 600 lectures and over 8000 hackers - many core contributors to the world’s leading open source projects. Complementing the LLVM developer meetings, the devroom at FOSDEM provides a great opportunity for LLVM developers and the wider open source community to get together, connect and discuss. We invite academic, industrial and hobbyist speakers to present their work on developing or using LLVM, Clang, LLD, LLDB, Compiler-rt, Flang, or any of the other technologies in the LLVM project. We are looking for: - Keynote speakers - Technical presentations (default length of 30 minutes including questions) related to the development of LLVM technologies or use of those technologies in other projects - Tutorials - Lightning talks (default length of 5 minutes) - Demos For MLIR-specific talks, please submit to the MLIR devroom. # Submission Please submit your proposal at https://fosdem.org/submit , clicking "Submit a proposal", and **selecting the LLVM track**. By default we will assume you submit a proposal for a full talk, aiming for 20 minutes of presenting and 10 minutes of questions. If you propose a different kind of talk and would prefer a different length, please do clearly state so in the "Submission Notes" field. We optimize the length of individual presentations taking into account all submissions and preferred length to achieve the best possible overall program. Presentations will be recorded and streamed. Sending your proposal implies giving permission to be recorded. The devroom only accepts in-person presentations, with a live stream and live chat for remote participants. The deadline for submitting proposals is 22 November 2026. Speakers will be notified of acceptance or rejection by 7 December 2026. Please find some advice on what constitutes a good proposal at the end of this CFP # Registration FOSDEM does not require any registration and is free of charge. All participants need to follow the https://fosdem.org/2027/practical/conduct/ and https://llvm.org/docs/CodeOfConduct.html . # Important dates - 22 November 2026: Deadline for submitting proposals - 7 December 2026: Announcement of accepted presentations and final schedule - 30 & 31 January 2027: FOSDEM # Organization Please use the LLVM Discourse thread at https://discourse.llvm.org/t/fosdem-2027-llvm-devroom-call-for-presentations... to discuss any issues or questions related to submitting a proposal or the organisation of the event. # Guidance on writing a proposal for the LLVM Dev Room This is a guide to help you submit a good proposal and increase your chances of your proposal being accepted. If you have never presented at an LLVM meeting, then do not fear this process. We are actively looking for new speakers who are excited about LLVM and helping grow the community through these educational talks! You do not need to be a long time developer to submit a proposal. The programs of the FOSDEM LLVM dev room from past years can give you an impression of what an abstract can look like: https://archive.fosdem.org/2014/schedule/track/llvm/ https://archive.fosdem.org/2015/schedule/track/llvm_toolchain/ https://archive.fosdem.org/2016/schedule/track/llvm_toolchain/ https://archive.fosdem.org/2017/schedule/track/llvm_toolchain/ https://archive.fosdem.org/2018/schedule/track/llvm_toolchain/ https://archive.fosdem.org/2019/schedule/track/llvm/ https://archive.fosdem.org/2020/schedule/track/llvm/ https://archive.fosdem.org/2022/schedule/track/llvm/ https://archive.fosdem.org/2023/schedule/track/llvm/ https://archive.fosdem.org/2024/schedule/track/llvm/ https://archive.fosdem.org/2025/schedule/track/llvm/ https://archive.fosdem.org/2026/schedule/track/llvm/ # General Guidelines - It should be clear from your abstract what your topic is, who your target audience is, and what are the takeaways for attendees. The program committee does not have time to read 10-page papers for each submission. - Talks about the use of an LLVM technology should include details about how LLVM is used and not only be about the resulting application. - Tutorials on "how to use X" in LLVM (or other subproject) are greatly desired and beneficial to many developers. Entry level topics are encouraged as well. - Typically a few paragraphs is sufficient. - For MLIR-specific talks, please send the submission to the MLIR devroom. We look forward to your submissions, and to seeing you at FOSDEM in January! The LLVM devroom organizers.
