As possibly the largest European Open Source Conference, FOSDEM attracts more than 600 lectures and over 8000 hackers - many core contributors of 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, LLDB, Compiler-rt, MLIR, 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.

Submission:

To submit a proposal, please create an account on the FOSDEM pentabarf interface. If you already have an account from previous years, please reuse that.

Submit your proposal following FOSDEM23 - Pentabarf 0.4.5, “Create Event”.
Please make sure you select “LLVM devroom” as the "Track”.
If your talk or tutorial requires a different duration then please request this in the “Duration” field. Please note that while we will try to accommodate the requested duration, there is no guarantee that we will be able to.

Presentations will be recorded and streamed. Sending your proposal implies giving permission to be recorded.

The deadline for receiving proposals is Sunday December 4th, 2022.
Speakers will be notified of acceptance or rejection by December 15th.
Please find some advice on what constitutes a good proposal at the end of this CFP.

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.

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.

Best regards,
the LLVM @ FOSDEM organisers
