Refereed Track Presentations Proposals (OPEN)
Submissions close: 11:59PM UTC on Wednesday, September 10, 2025.
Decision Notifications: September 28, 2025.
The Call for Refereed Presentation Proposals for the 2025 edition of the Linux Plumbers Conference (LPC) is now open. We plan to hold LPC in Tokyo, Japan on December 11-13, 2025.
Submitters should ideally be able to give their presentation in person, although presenting remotely will be possible if necessary. Expectation is that the presentation will be done live in either case, to maximize audience interaction. Please see our website or social media for regular updates.
Refereed Presentations are 45 minutes in length and should focus on a specific aspect of the “plumbing” in a Linux system. Examples of Linux plumbing include core kernel subsystems, init systems, core libraries, windowing systems, management tools, device support, media creation/playback, testing, and so on. The best presentations are not about finished work, but rather problem statements, proposals, or proof of-concept solutions that require face-to-face discussions and debate.
BOFs will also be accepted on Refereed track and be recorded, if submitted while the CFP is open.
The Refereed Presentations track will be running throughout all three days of the conference.
Linux Plumbers Conference Program Committee members will be reviewing all submitted proposals. High-quality submissions that cannot be accepted due to the limited number of slots will be forwarded to organizers of suitable Linux Plumbers Microconferences for further consideration.
Submissions are due on or before 11:59PM UTC on Wednesday, September 10, 2025.
Microconference Proposals (new Microconferences: OPEN)
Submissions close: June 29, 2025 - MC leads notified: from June 30, 2025
A microconference contains several sessions based on the same general topic. Each session will be between 15 to 30 minutes in length and be discussion oriented. A microconference submission should explain the topic that will be discussed in these sessions and give a few examples of what those sessions would discuss.
In past years, Microconferences were organized around topics such as security, scalability, energy efficiency, toolchains, containers, printing, system boot, Android, scheduling, filesystems, tracing, or real-time. The LPC Microconference track is open to a wide variety of topics as long as it is focused, concerned with interesting problems, and is related to open source and the wider Linux ecosystem.
The Microconference submission should not only describe the overall topic and some examples of what discussion topics would be about, it should also list the key people who need to attend to make sure that the discussions can be followed through with action.
Microconferences that have been at previous LPCs should list results and accomplishments from those previous sessions in the submission as well as cover follow-up work and new topics.
Kernel Summit Presentations Proposals (OPEN)
Submissions were due on or before 11:59PM UTC on Wednesday, September 10, 2025.
The goal of the Kernel Summit track will be to provide a forum to discuss specific technical issues. The program committee will also consider "information sharing" topics if they are clearly of interest to the wider development community (i.e., advanced training in topics that would be useful to kernel developers).
In addition to submitting proposals here, please also send an e-mail for each submission to the ksummit@lists.linux.dev mailing list with the subject prefix [TECH TOPIC].
We will be reserving roughly half the Kernel Summit slots for last-minute discussions that will be scheduled during the week of Plumber's, in an "unconference style".
