Submission time for Linux Plumbers 2025

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.

That’s a wrap! Thanks everyone for Linux Plumbers 2024

Thank you to everyone who attended Linux Plumbers 2024 both in person and virtually!

This year we were able to accommodate huge demand for in-person participation and we were glad to see more than 700 people in the Austria Center.
As in previous years after the pandemic we also had a virtual component with more than 200 participants.

We had a lot of great content in Refereed Track, Kernel Summit, eBPF and Networking Summits and Toolchains Track and a lot of productive discussions in 24 microconferences.

There also were 25 Birds-of-a-Feather sessions, many of them were added during the event to continue a discussion that started in a microconference or in the Hallway Track.

There are recordings of live streams and we hope to have recordings of all the sessions soon.

Finally, I want to thank all those that were involved in making Linux Plumbers the best technical conference there is. This would not have happened without the hard work from the planning committee (Alice Ferrazzi, André Almeida, Christian Brauner, David Woodhouse, James Bottomley, Kate Stewart, Lorenzo Pieralisi, Shuah Khan, Song Liu, Steve Rostedt, Tim Bird), the runners of the Networking and BPF Summit tracks, the Toolchain track, Kernel Summit, and those that put together the very productive microconferences. I would also like to thank all those that presented as well as those who attended both in-person and virtually.

I want to thank our sponsors for their continued support, without them Linux Plumbers Conference would not be possible.

And a very special thanks to the Linux Foundation and their staff who did really great job behind the scenes and on-site to make this conference run smoothly. Their work is greatly appreciated by the LPC planning committee.

Sincerely,

Mike Rapoport
Linux Plumbers 2024 Conference chair

Welcome to the Android Micro-conference!

Every year the Android Micro-conference brings the upstream Linux community and the Android systems developers together at the Linux Plumbers Conference. They discuss how they can effectively engage the existing issues and collaborate on upcoming changes to the Android platform and their upstream dependencies.

This year Android MC is scheduled to start at 10am on Friday, 20th Sep at Hall L1 (Austria Center). Attending Android MC gives you a chance to contribute to the broader discussion on Android platform ecosystem and Linux kernel development. You can share your own experiences, offer feedback, and help shape the future direction of these technologies.

Discussion topics for this year include:

Android MC will be followed by a Android BoF session, which will be a audience directed discussion. It can be a follow-up of the discussions from any of the Android MC topics or a free-form discussion on Android related topics.

Registration is now reopened

It’s better late than never.

This year there was a huge demand to attend Linux Plumbers Conference in person and at last we were able to add more places and reopen the registration.

System Boot and Security Microconference CFP

The System Boot and Security Microconference has been a critical platform for enthusiasts and professionals working on firmware, bootloaders, system boot, and security. This year, the conference focuses on the challenges of upstreaming boot process improvements to the Linux kernel. Cryptography, an ever-evolving field, poses unique demands on secure elements and TPMs as newer algorithms are introduced and older ones are deprecated. Additionally, new hardware architectures with DRTM capabilities, such as ARM’s D-RTM specification and the increased use of fTPMs in innovative applications, add to the complexity of the task. This is the fifth time the conference has been held in the last six years.

Trusted Platform Modules (TPMs) for encrypting disks have become widespread across various distributions. This highlights the vital role that TPMs play in ensuring platform security. As the field of confidential computing continues to grow, virtual machine firmware must evolve to meet end-users’ demands, and Linux would have to leverage exposed capabilities to provide relevant security properties. Mechanisms like UEFI Secure Boot that were once limited to OEMs now empower end-users. The System Boot and Security Microconference aims to address these challenges collaboratively and transparently. We welcome talks on the following technologies that can help achieve this goal.

  • TPMs, HSMs, secure elements
  • Roots of Trust: SRTM and DRTM
  • Intel TXT, SGX, TDX
  • AMD SKINIT, SEV
  • ARM DRTM
  • Growing Attestation ecosystem
  • IMA
  • TrenchBoot, tboot
  • TianoCore EDK II (UEFI), SeaBIOS, coreboot, U-Boot, LinuxBoot, hostboot
  • Measured Boot, Verified Boot, UEFI Secure Boot, UEFI Secure Boot Advanced Targeting (SBAT)
  • shim
  • boot loaders: GRUB2, systemd-boot/sd-boot, network boot, PXE, iPXE
  • UKI
  • u-root
  • OpenBMC, u-bmc
  • legal, organizational, and other similar issues relevant to people interested in system boot and security.

If you want to participate in this microconference and have ideas to share, please use the Call for Proposals (CFP) process. Your submissions should focus on new advancements, innovations, and solutions related to firmware, bootloader, and operating system development. It’s essential to explain clearly what will be discussed, why, and what outcomes you expect from the discussion.

Edit: The submission deadline has been updated to July 14th!

Sched-Ext: The BPF extensible scheduler class Microconference CFP

sched_ext is a Linux kernel feature which enables implementing host-wide, safe kernel thread schedulers in BPF, and dynamically loading them at runtime. sched_ext enables safe and rapid iterations of scheduler implementations, thus radically widening the scope of scheduling strategies that can be experimented with and deployed, even in massive and complex production environments.

sched_ext was first sent to the upstream list as an RFC patch set back in November 2022. Since then, the project has evolved a great deal, both technically, as well as in the significant growth of the community of sched_ext users and contributors.

This MC is the space for the community to discuss the developments of sched_ext, its impact on the community, and to outline future strategies aimed at integrating this feature into the Linux kernel and mainstream Linux distributions.

Ideas of topics to be discussed include (but are not limited to):

  • Challenges and plans to facilitate the upstream merge of sched_ext
  • User-space scheduling (offload part / all of the scheduling from kernel to user-space)
  • Scheduling for gaming and latency-sensitive workloads
  • Scheduling & cpufreq integration
  • Distro support

While we anticipate having a schedule with existing talk proposals at the MC, we invite you to submit proposals for any topic(s) you’d like to discuss. Time permitting, we are happy to readjust the schedule for additional topics that are of relevance to the sched_ext community.

Submissions are made via LPC submission system, selecting the track Sched-Ext: The BPF extensible scheduler class.

We will consider the submissions until July 12th.

In-person registration is sold out

We are giving waitlist priority to new attendees and people expected to contribute content.

Rust Microconference CFP

The Rust Microconference returns this year again. It covers both Rust in the kernel and Rust in general.

The submission deadline is July 14th. Submissions are made via the LPC submission system, selecting Rust MC for Track. Please see The Ideal Microconference Topic Session as well.

Possible Rust for Linux topics:

  • Rust in the kernel (e.g. status update, next steps).
  • Use cases for Rust around the kernel (e.g. subsystems, drivers, other modules…).
  • Discussions on how to abstract existing subsystems safely, on API design, on coding guidelines.
  • Integration with kernel systems and other infrastructure (e.g. build system, documentation, testing and CIs, maintenance, unstable
    features, architecture support, stable/LTS releases, Rust versioning, third-party crates).
  • Updates on its subprojects (e.g. klint, pinned-init).
  • Rust versioning requirements and using Linux distributions’ toolchains.

Possible Rust topics:

  • Language and standard library (e.g. upcoming features, stabilization of the remaining features the kernel needs, memory model).
  • Compilers and codegen (e.g. rustc improvements, LLVM and Rust, rustc_codegen_gcc, gccrs.
  • Other tooling and new ideas (Coccinelle for Rust, bindgen, Compiler Explorer, Cargo, Clippy, Miri).
  • Educational material.
  • Any other Rust topic within the Linux ecosystem.

Hope to see you there!

In memory of Daniel Bristot de Oliveira

It comes with great sadness that on June 24th, 2024 we lost a great contributor to the Linux Plumbers Conference and the whole of Linux generally. Daniel Bristot de Oliveira passed away unexpectedly at the age of 37. Daniel has been an active participant of Linux Plumbers since 2017. Not only has he given numerous talks, which were extremely educational, he also took leadership roles in running Microconferences. He was this year’s main Microconference runner for both the Scheduler Microconference as well as the Real-Time Microconference. This year’s conference will be greatly affected by his absence. Many have stated how Daniel made them feel welcomed at Linux Plumbers. He always had a smile, would make jokes and help developers come to a conclusion for those controversial topics. He perfectly embodied the essence of what Linux Plumbers was all about. He will be missed.
