# MLIR Devroom @ FOSDEM'2027 Forum link: https://discourse.llvm.org/t/fosdem-2027-mlir-devroom-call-for-presentations... ## Call For Participation We are pleased to announce that MLIR will have a devroom at FOSDEM, which takes place on 30 & 31 January 2027 in Brussels, Belgium. The room is scheduled for the Sunday afternoon. This is in addition to the already popular LLVM devroom. We invite academic, industrial and hobbyist speakers to present their work on developing or using MLIR and MLIR-based projects (such as Lighthouse, Torch-MLIR, IREE,) and MLIR adjacent (such as xDSL, VeIR). We are looking for: * Keynote speakers * Technical presentations (default length of 30 minutes including questions) related to the development of MLIR technologies or use of those technologies in other projects * Tutorials * Lightning talks (default length of 5 minutes) * Demos For LLVM-specific talks, please submit to the LLVM devroom. ## Submission Please submit your proposal at https://fosdem.org/submit, clicking “Submit a proposal”, and selecting the MLIR 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. This year, FOSDEM 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 Code of Conduct — 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 this LLVM Discourse thread to discuss any issues or questions related to submitting a proposal or the organisation of the event. ## Guidance on writing a proposal for the MLIR Dev Room Please follow the LLVM guidance and look at their previous talks, starting with 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 MLIR is used and not only be about the resulting application. Tutorials on “how to use X” in MLIR (or other subproject) are greatly desired and beneficial to many developers. Entry level topics are encouraged as well. Typically a few paragraphs is sufficient. We look forward to your submissions, and to seeing you at FOSDEM in January! The MLIR devroom organizers.
