Submissions for the Refereed Track and Microconferences are now open. Linux Plumbers will be held this year in Tokyo from December 11th – 13th (Note, the 13th is on a Saturday).

The Refereed presentations are 45 minutes in length and should focus on a specific aspect of the “plumbing” in a Linux ecosystem. Examples of Linux plumbing include core kernel subsystems, init systems, core libraries, toolchains, 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.

The Microconferences are 3 and a half hours of technical discussion, broken up into 15 to 30 minute subtopics. The only presentations allowed are those that are needed to bring the audience up to speed and should not last more than half the allotted time for the subtopic. To submit a Microconference, provide a topic, some examples of subtopics to be discussed and a list of key people that should be present to have meaningful discussions. For Microconferences that have been to Linux Plumbers in the past, they should provide a list of accomplishments that were a direct result of the discussions from their previous sessions (with links to patches and such).

Presentations and Microconference subtopic leads should ideally be physically present at the conference. Remote presentations may be available but are strongly discouraged.

The Refereed submissions end at 11:59PM UTC on Wednesday, September 10, 2025.
The Microconference submissions end at 11:59PM UTC on Sunday, June 29, 2025.

Go ahead and submit your Refereed track presentation or Microconference topic. We are looking forward to seeing the great content that is submitted that makes Linux Plumbers the best technical conference there is.
