Submission deadline for LPC refereed track proposals extended by a week

The deadline for submitting refereed track proposals for the 2024 Linux Plumbers Conference has been extended until 23 June.

If you have already submitted a proposal, thank you very much! For the rest of you, there is one additional week in which to get your proposal submitted. We very much look forward to seeing what you all come up with.

Registration for LPC 2024 is open

We’re happy to announce that registration for LPC 2024 is now open. To register please go to our attend page.

To try to prevent the instant sellout we had in previous years we are keeping our cancellation policy of no refunds, only transfers of registrations. You will find more details during the registration process. LPC 2024 follows the Linux Foundation’s health & safety policy.

As usual we expect to sell our rather quickly so don’t delay your registration for too long!

Update on the Microconference situation

Unfortunately we still do not know the total cost of the 4th track yet. We are still in the process of looking at the costs of adding another room, but we do not want to delay the acceptance of topics to Microconferences any further. We have decided to accept all pending Microconferences with one caveat. That is, we are not accepting the rest as full Microconferences. The Microconferences being accepted now will become one of the following at Linux Plumbers 2024:

  • A full 3 hour Microconference
  • A 1 and a half hour Microconference (Nanoconference)
  • A full 3 hour Microconference but without normal Audio/Video

That last one is another option we are looking at. The main cost to having a 4th track is the manned AV operations. But we could add the 4th track without normal AV. Instead, these would get a BBB room where an Owl video camera (or the like) and a Jabra speaker will be in place. The quality of the AV will not be as good as having a fully manned room, but this would be better than being rejected from the conference, or having half the time of a full microconference.

Even with a 4th track, two still need to become Nanoconferences.

In the mean time, we will be accepting the rest of the Microconferences so that they can start putting together content. How they are presented at Linux Plumbers is still to be determined.

Note that this also means we will likely be dropping the 3 free passes that a Microconference usually gets down to only 2 passes.

The accepted Microconferences (as full, half or no A/V) are:

  • Sched_ext
  • Containers and Checkpoint/Restore
  • Confidential Computing
  • Real-Time
  • Build Systems
  • RISC-V
  • Compute Express Link
  • X86
  • VFIO/IOMMU/PCI
  • System Boot and Security
  • Zone Storage
  • Internet of Things
  • Embedded
  • Complex Cameras
  • Power Management and Thermal Control
  • Kernel <-> Userspace/Init/System Management Boundaries and APIs

Awesome amount of Microconference submissions!

The Call-for-Proposals for Microconferences has come to a close, and with that, this year’s list of Microconferences is to be decided. A Microconference is a 3 and a half hour session with a half hour break (giving a total of 3 hours of content). Linux Plumbers has three Microconference tracks running per day, with each track having two Microconferences (one in the morning and one in the afternoon). Linux Plumbers runs for three days allowing for 18 Microconferences total (2 per track, with 3 tracks a day for 3 days).

This year we had a total of 26 quality submissions! Linux Plumbers is known as the conference that gets work done, and its success is proof of that. But sometimes success brings its own problems. How can we accept 26 Microconferences when we only have 18 slots to place them? Two of the Microconferences have agreed to merge as one bringing the total down to just 25. But that still is 7 more than we can handle.

We want to avoid rejecting 7 microconferences, but to do so, we need to make compromises. The first idea we have is to add a 4th Microconference track. But that still only gives us 6 more slots. As it will also require more A/V and manpower, the cost will increase and may not be within the budget to do so.

Pros to a 4 track are:

  • Have 24 full Microconferences and reject one (or 23 and keep 2 as per the next option).

Cons to a 4 track are:

  • Increased costs.
  • Having 4 Microconference tracks running simultaneously will cause more conflicts in the schedule. People have complained in the past about conflicts between sessions with just 3 tracks, having 4 will exacerbate the situation.
  • Still may need to reject 1 Microconference.

Another solution is to create a half Microconference (Nanoconference?). That is an hour and a half session, run the same as the full sessions, with the 30 minute break between two Nanoconferences. Doing so will allow for 11 full Microconferences and 14 Nanoconferences which will allow for all submissions to be accepted and fit within the 3 tracks.

The difference between a Nanoconference and a BOF is that a Nanoconference still has all the rules of a Microconference. That is, all sessions should be strictly discussion focus. If presentations are needed, they should be submitted as Refereed talks (the CFP for them are still open). A BOF is usually focused on a single issue. A Nanoconference should still be broken up into small discussions about different issues with sessions lasting 15 to 20 minutes each.

Pros for Nanoconferences are:

  • Can accommodate all submitted Microconferences.

Cons for Nanoconferences are:

  • Shortened time for Microconferences, even for topics in the past that had filled a full Microconference may now only get half the time.

Note, as BOFs will be in a separate track, a Nanoconference may be able to still submit for topics there (BOF submissions are still open).

Currently, we also give out 3 free passes to each Microconference that can be handed to anyone in their session. For 18 Microconferences, that is 54 passes. This will not be feasible to give out 3 passes to 25 Microconferences (totaling 75 passes), thus one solution is to drop it down to 2 free passes. The problem with passes is still an issue with the Nanoconference approach, as you can not give out 1 and a half passes. Thus, the Nanoconferences may only get 1 pass each, or perhaps have both the Microconferences and Nanoconferences all get just 2 passes each.

Anyway, since the above solutions still allow for 11 full Microconferences, we have accepted 9 so far. They are:

  • Android
  • KVM
  • Kernel Memory Management
  • Scheduling
  • Rust
  • Kernel Testing and Dependability
  • Graphics and DRM
  • Safe Systems with Linux
  • Tracing / Perf events (This is the merged Microconference)

We are still weighing our options so stay tuned for updates on the situation, and thank you to all the Microconference submitters that make
Linux Plumbers the best technical conference around!

Networking Track

Linux Plumbers Conference 2024 is pleased to host the Networking Track!

LPC Networking track is an in-person manifestation of the netdev mailing list, bringing together developers, users and vendors to discuss topics related to Linux networking. Relevant topics span from proposals for kernel changes, through user space tooling, netdev testing and CI, to presenting interesting use cases, new protocols or new, interesting problems waiting for a solution.

The goal is to allow gathering early feedback on proposals, reach consensus on long running mailing list discussions and raise awareness of interesting work and use cases.

After four years of co-locating BPF & Networking Tracks together this year we separated the two, again. Please submit to the track which feels suitable, the committee will transfer submissions between tracks as it deems necessary.

Please come and join us in the discussion. We hope to see you there!

eBPF Track

Linux Plumbers Conference 2024 is pleased to host the eBPF Track!

After four years in a row of co-locating eBPF & Networking Tracks together, this year we separated the two in order to allow for both tracks to grow further individually as well as to bring more diversity into LPC by attracting more developers from each community.

The eBPF Track is going to bring together developers, maintainers, and other contributors from all around the globe to discuss improvements to the Linux kernel’s BPF subsystem and its surrounding user space ecosystem such as libraries, loaders, compiler backends, and other related low-level system tooling.

The gathering is designed to foster collaboration and face to face discussion of ongoing development topics as well as to encourage bringing new ideas into the development community for the advancement of the BPF subsystem.

Proposals can cover a wide range of topics related to BPF covering improvements in areas such as (but not limited to) BPF infrastructure and its use in tracing, security, networking, scheduling and beyond, as well as non-kernel components like libraries, compilers, testing infra and tools.

Please come and join us in the discussion. We hope to see you there!

Toolchains Track

Linux Plumbers Conference 2024 is pleased to host the Toolchains Track!

The aim of the Toolchains track is to fix particular toolchain issues which are of the interest of the kernel and, ideally, find solutions in situ, making the best use of the opportunity of live discussion with kernel developers and maintainers. In particular, this is not about presenting research nor abstract/miscellaneous toolchain work.

The track will be composed of activities, of variable length depending on the topic being discussed. Each activity is intended to cover a particular topic or issue involving both the Linux kernel and one or more of its associated toolchains and development tools. This includes compiling, linking, assemblers, debuggers and debugging formats, ABI analysis tools, object manipulation, etc. Few slides shall be necessary, and most of the time shall be devoted to actual discussion, brainstorming and seeking agreement.

Please come and join us in the discussion. We hope to see you there!
