Additional early bird slots available for LPC 2019

The Linux Plumbers Conference (LPC) registration web site has been showing “sold out” recently because the cap on early bird registrations
was reached. We are happy to report that we have reviewed the registration numbers for this year’s conference and were able to open more early bird registration slots. Beyond that, regular registration will open July 1st. Please note that speakers and microconference runners get free passes to LPC, as do some microconference presenters, so that may be another way to attend the conference. Time is running out for new refereed-track and microconference proposals, so visit the CFP page soon. Topics for accepted microconferences are welcome as well.

LPC will be held in Lisbon, Portugal from Monday, September 9 through Wednesday, September 11.

We hope to see you there!

Tracing Microconference Accepted into 2019 Linux Plumbers Conference

We are pleased to announce that the Tracing Microconference has been accepted into the 2019 Linux Plumbers Conference! Its return to Linux Plumbers shows that tracing is not finished in Linux, and there continue to be challenging problems to solve.

There’s a broad list of ways to perform Tracing in Linux. From the original mainline Linux tracer, Ftrace, to profiling tools like perf, more complex customized tracing like BPF and out-of-tree tracers like LTTng, systemtap, and Dtrace. Part of the trouble with tracing within Linux is that there is so much to choose from. Each of these have their own audience, but there is a lot of overlap. This year’s theme is to find those common areas and combine them into common utilities.

There is also a lot of new work that is happening and discussions between top maintainers will help keep everyone in sync, and provide good direction for the future.

Expected topics include:

  • bpf tracing – Anything to do with BPF and tracing combined
  • libtrace – Making libraries from our tools
  • Packaging – Packaging these libraries
  • babeltrace – Anything that we need to do to get all tracers talking to each other
  • Those pesky tracepoints – How to get what we want from places where trace events are taboo
  • Changing tracepoints – Without breaking userspace
  • Function tracing – Modification of current implementation
  • Rewriting of the Function Graph tracer – Can kretprobes and function graph tracer merge as one
  • Histogram and synthetic tracepoints – Making a better interface that is more intuitive to use

Come and join us and not only learn but help direct the future progress of tracing inside the Linux kernel and beyond!

If you have another tracing topic idea, please send it to Steven Rostedt: rostedt@goodmis.org .

We hope to see you there!

RISC-V microconference accepted for the 2019 Linux Plumbers Conference

The open nature of the RISC-V ecosystem has allowed contributions from both academia and industry leading to an unprecedented number of new hardware design proposals in a very short time span. Linux support is the key to enabling these new hardware options. Since last year’s Plumbers, many kernel features were added to RISC-V. To name a few, we now have out-of-box 32-bit and eBPF support, some key issues with Linux boot process have been addressed, and hypervisor support is on its way.

Last year’s RISC-V microconference was such a success that we would like to repeat that again this year by focusing on finding solutions and discussing ideas that require kernel changes.

Topics for this year microconference are expected to cover:

  • RISC-V Platform Specification Progress, including some extensions such as power management
  • Fixing the Linux boot process in RISC-V (RISC-V now has better support for open source boot loaders like U-Boot and coreboot compared to last year. As a result of this developers can use the same boot loaders to boot Linux on RISC-V as they do in other architectures, but there’s more work to be done)
  • RISC-V hypervisor emulation
  • NOMMU Linux for RISC-V
  • Any other subject of interest

If you’re interested in participating in this microconference or have other topics to propose, please contact Atish Patra (atish.patra@wdc.com) or Palmer Dabbelt (palmer@dabbelt.com)

LPC will be held in Lisbon, Portugal from Monday, September 9 through Wednesday, September 11.

We hope to see you there!

BPF microconference accepted into 2019 Linux Plumbers Conference

We are pleased to announce that the BPF microconference has been accepted into the 2019 Linux Plumbers Conference! Last year’s BPF microconference was such a success that it will be held again this year.

BPF along with its just-in-time (JIT) compiler inside the Linux kernel allows for versatile programmability of the kernel and plays a major role in networking (XDP, tc BPF, etc.), tracing (kprobes, uprobes, tracepoints) and security (seccomp, landlock) subsystems.

Since last year’s Plumbers Conference, many of the discussed improvements have been tackled and found their way into the Linux kernel such as significant steps towards allowing for a compile-once paradigm with the help of BTF and global data support as well as considerable verifier scalability improvements to name a few. The topics proposed for this year’s event include:

– libbpf, loader unification
– Standardized BPF ELF format
– Multi-object semantics and linker-style logic for BPF loaders
– Verifier scalability work towards 1 million instructions
– Sleepable BPF programs
– BPF loop support
– Indirect calls in BPF
– Unprivileged BPF
– BPF type format (BTF)
– BPF timers
– bpftool
– LLVM BPF backend, JITs and BPF offloading
– and more

Come join us and participate in the decision making of one of the most cutting edge advancements in the Linux kernel!

See here for a detailed preview of the proposed and accepted topics. Please feel free to submit your discussion proposals to Alexei or Daniel: lpc-bpf@vger.kernel.org

We hope to see you there!

Linux Plumbers Conference 2019 Call for Bird of a Feather (BoF) Session Proposals

On the heels of the previous announcements, we are also pleased to announce the Bird of a Feather (BoF) Session Proposals for the 2019 edition of the Linux Plumbers Conference, which will be held in Lisbon, Portugal on September 9-11 in conjunction with the Linux Kernel Maintainer Summit.

BoFs are free-form get-togethers for people wishing to discuss a particular topic. As always, you only need to submit proposals for BoFs you want to hold on-site. In contrast, and again as always, informal BoFs may be held at local drinking establishments or in the “hallway track” at your convenience.

For more information on submitting a BoF session proposal, see the following:

https://www.linuxplumbersconf.org/event/4/abstracts

Please note that the submission system is the same as 2018. If you created an user account last year, you will be able to re-use the same credentials to submit and modify your proposal(s) this year.

The call for Microconferences and Refereed-Track proposals are also open, and we hope to see you in Lisbon this coming September!

Results from the 2018 LPC survey

Thank you to everyone who participated in the survey after Linux Plumbers in 2018. We had 134 responses, which, given the total number of conference participants of around 492, has provided confidence in the feedback.

Overall: 85% of respondents were positive about the event, with only 2% actually saying they were dissatisfied. Co-locating with Kernel Summit proved popular, so we will be co-locating with Kernel Summit in 2019. Co-locating with Networking Summit was also well received, so we will be doing that again this year, too. Conference participation was up from 2017 and we sold out again this year. 98% of those that registered were able to attend.

Based on feedback from last year’s survey, we videotaped all of the sessions, and the videos are now posted. There are over 100 hours of video in our YouTube channel or you can access them by visiting the detailed schedule and clicking on the video link in the presentation materials section of any given talk or discussion. The Microconferences are recorded as one long video block, but clicking on the video link of a particular discussion topic will take you to the time index in that file where the chosen discussion begins.

Venue: 67% of survey respondents considered the size of attendees to be just right, however 25% would have like to have seen more able to attend. In general, 43% of respondents considered the venue size to be a good match, but a significant portion would have preferred it to be bigger (45%) as well. The room size was considered effective for participation by 95% of the respondents, however there was a clear indication in the comments that we need to figure out a better way to allocate rooms based on expected participants, as some ended up overflowing. There is some desire for additional electrical outlets to be made available, which will be looked into for the 2019 event.

Content: In terms of track feedback, Linux Plumbers Refereed track and Kernel Summit track were indicated as very relevant by almost all respondents who attended. The Networking track had fewer participants responding on the survey, but was positively reviewed as well. Hallway track continues to be regarded as very relevant, and appreciated.

Communication: This year we had a new website, and participants were able to navigate through it and find the session needed. In the feedback, there were some requests to integrate scheduling app capabilities (and attendee room size); the committee will look into options for that.

Events: Craft Beer was the most popular event and had favorable feedback from respondents. There were some concerns expressed in the written feedback that we didn’t clarify there were non-alcoholic options available there, and we’ll take note to communicate this better in future. The final closing event venue was originally planned for conference attendance similar to the prior year; the increase of 20% to 492 attendees, impacted this event, and the perception was that it was too crowded and had insufficient food from the comments.

There were lots of great suggestions to the “what one thing would you like to see changed” question, and the program committee has been studying them to see what is possible to implement this year. Thank you again to the participants for their input and help on making the Linux Plumbers Conference better in 2019 and the future.

Linux Plumbers Conference 2019 Call for Refereed-Track Proposals

We are pleased to announce the Call for Refereed-Track talk proposals for the 2019 edition of the Linux Plumbers Conference, which will be held in Lisbon, Portugal on September 9-11 in conjunction with the Linux Kernel Maintainer Summit.

Refereed track presentations are 50 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, toolchains, container runtimes, core libraries, windowing systems, management tools, device support, 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.

For more information on submitting a Refereed-Track talk proposal, see the following:

https://www.linuxplumbersconf.org/event/4/abstracts

Please note that the submission system is the same as 2018. If you created an user account last year, you will be able to re-use the same credentials to submit and modify your proposal(s) this year.

The call for Microconferences proposals is also open, and we hope to see you in Lisbon this coming September!

Linux Plumbers Conference 2019 Call for Microconference Proposals

We are pleased to announce the Call for Microconferences for the 2019 edition of the Linux Plumbers Conference, which will be held in Lisbon, Portugal on September 9-11 in conjunction with the Linux Kernel Maintainer Summit.

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, services, UI, and so forth, but can also focus on cross-cutting concerns such as security, scaling, energy efficiency, toolchains, container runtimes, 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. For more information on submitting a microconference proposal, see the following:

https://www.linuxplumbersconf.org/event/4/abstracts

Please note that the submission system is the same as 2018. If you created an user account last year, you will be able to re-use the same credentials to submit and modify your proposal(s) this year.

Look for the upcoming call for refereed-track proposals, and we hope to see you in Lisbon this coming September!
