Birds of a Feather (BoF) proposals - Open

BoF sessions have been very popular at LPC. These are free-form get-togethers for people wishing to discuss a particular topic. Please submit proposals for BoFs you wish to hold online through the LPC 2021 platform. This year informal BoFs that might been have held at local drinking establishments or in the “hallway track” will not be possible, due to the virtual nature of the conference. So submit your proposal to make your BoF part of LPC 2021.

Now that the official CFP workflow is closed. If you would like to submit a last minute both during LPC 2021, please email your idea to

Microconference topics proposals - Closed

Submissions close: (16 September) - Speakers notified: (16 September)

This year again, microconference topics can be submitted using the LPC CfP process embedded inside the LPC web platform.

To suggest a topic for a microconference, please follow the Refereed-track proposal instructions and select the microconference topic as the track you wish to submit to.

Kernel summit track proposals - Closed

Submissions close: (now 2 July) - Speakers notified: (now 23 July)

[Edited to extend the deadlines by 1 week]

Kernel summit sessions are 45 minutes in length. The goal of the Kernel Summit track will be to provide a forum to discuss specific technical issues that would be easier to resolve in person than over e-mail. 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 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". The Kernel Summit program committee is comprised of: Jens Axboe, Arnd Bergmann, Jon Corbet, Greg Kroah-Hartman, and Ted Ts'o.

Networking and BPF track proposals - Closed

Submissions close: (13 August) - Speakers notified: (20 August)

The track will be composed of talks, 40 minutes in length (including Q&A discussion). Topics will be advanced Linux networking and/or BPF related.

This year's Networking and BPF track technical committee is comprised of: David S. Miller, Jakub Kicinski, Eric Dumazet, Alexei Starovoitov, Daniel Borkmann, and Andrii Nakryiko.

The track committee is therefore seeking proposals of 40 minutes in length (including Q&A discussion), optionally accompanied by papers of 2 to 10 pages in length.

GNU Tools track proposals - Closed

Submissions close: (31 August) - Speakers notified: (5 September)

The purpose of this virtual meeting is to gather all GNU tools developers, discuss current/future work, coordinate efforts, exchange reports on ongoing efforts, discuss development plans for the next 12 months, developer tutorials and any other related discussions.

The format of the meeting will be different to accommodate its virtual nature, talks and discussions will be shorter to allow us to fit in as many speakers/discussions as possible. However we may not be able to include every proposal.

We are inviting every developer working in the GNU tool chain: GCC, GDB, binutils, runtimes, etc. In particular this is an opportunity for participation by members of the community who are not able to travel to our regular GNU Tools Cauldron.

Make sure you read the instructions for the GNU Tools Track at the top of the Submission Form

Microconference proposals - (Closed)

Submissions close: (12 June) - MC Runners Notified: (26 June)

A microconference is a collection of collaborative sessions focused on problems in a particular area of the Linux plumbing, which includes the kernel, libraries, utilities, UI, and so forth, but can also focus on cross-cutting concerns such as security, scaling, energy efficiency, or a particular use case. Good microconferences result in solutions to these problems and concerns, while the best microconferences result in patches that implement those solutions.

Linux Plumbers Conference Program Committee members will work with the authors of microconference proposals to help shape them into an acceptable submission. Microconferences will be accepted in the order of when their submissions reach a level of quality, and while microconference time slots are available.

Requirements of a microconference submission:

  • Title - One line summary of for the category of topics
  • Description - describe the category in a way other developers know what is expected at the microconference.
  • List of possible topics to discuss and description of what those topics are (links to sites, email archives, etc that help the audience understand the issue and help be able to join the discussions).
  • List of key people that need to attend the microconference to make sure all decisions made can be implemented without a veto from upstream.

Refereed-track talk proposals - Closed

Submissions close: (2 July) - Speakers notified: (now 02 August)

Refereed track presentations are 45 minutes in length (which includes time for questions and discussion) and should focus on a specific aspect of the "plumbing" in the Linux system. Examples of Linux plumbing include core kernel subsystems, core libraries, windowing systems, management tools, device support, container run-times, media creation/playback, and so on. The best presentations are not about finished work, but rather problems, proposals, or proof-of-concept solutions that require face-to-face discussions and debate.

Linux Plumbers Conference Program Committee members will be reviewing all submitted proposals. High-quality submission that cannot be accepted due to the limited number of slots will be forwarded to the Microconference leads for further consideration. We also encourage submitters to consider BoF sessions and the unconference.

The call for proposals is closed.
