The Embedded Linux Conference Europe took place online last week. While we definitely missed the experience of an in-person event, we strongly participated to this conference with no less than 7 talks on various topics showing Bootlin expertise in different fields: Linux kernel development in networking, multimedia and storage, but also build systems and tooling. We’re happy to be publishing now the slides and videos of our talks.
In these times of COVID19, pretty much all of the existing conferences have moved to an online format. For example, the Embedded Linux Conference Europe is going to take place next week, online, and Bootlin will significantly contribute to the event with no less than 7 talks on a wide range of topics.
But this trend for online conferences has also spurred the creation of new events. And specifically, we’re happy to announce the creation of a new conference oriented towards our favorite topic of embedded systems: Live Embedded Event. It will take place online on December 3 and will have a broader range of topics covered than ELC typically has, as Live Embedded Event is open to non-Linux embedded topics, hardware platform and interfaces discussions, and more.
The event is mainly organized by four French companies specialized in embedded systems, and we expect the contents to be a mix of talks in English and in French. Speaking of contents, the Call For Papers is open until November 10, so you can have the chance to share your knowledge about embedded topics, show your expertise, and meet new users and customers. And of course, you can also simply register as an attendee: the event is free !
The schedule for the next Embedded Linux Conference Europe has been recently published, and Bootlin will once again be strongly present at this (virtual) event by giving a number of presentations. The registration for ELC-E is open, and due to the virtual nature of the event, the registration cost is only $50, which makes is accessible to pretty much everybody.
- From the Camera Sensor to the User, the Journey of a Video Frame. In this talk, Bootlin engineer Maxime Chevallier will share his experience working in the Video4Linux subsystem, implementing support for the Rockchip camera interface controller, and a PAL/NTSC decoder used as the input source. Talk on Monday October 26 at 18:30 GMT.
- Yocto Project and OpenEmbedded: A Collection of Best Practices. In this talk, Bootlin engineer, and Yocto Project expert and trainer Alexandre Belloni will share his experience of using Yocto Project and OpenEmbedded through a collection of best practices. There are indeed numerous ways of using OpenEmbedded and the Yocto Project, but some ways and solutions are better than others! Talk on Tuesday October 27 at 13:00 GMT.
- Building Embedded Debian and Ubuntu Systems with ELBE. In this talk, Köry Maincent will share his experience using the ELBE build system, which can be used to automate the process of creating embedded Linux systems based on Debian or Ubuntu. Köry has contributed to ELBE the support for building Ubuntu systems, and has used ELBE on two different projects. This is an interesting alternative to the traditional cross-compilation approach taken by Yocto Project, OpenEmbedded or Buildroot. Talk on Tuesday October 27 at 15:15 GMT.
- Using Visual Studio Code for Embedded Development. In this talk, Michael Opdenacker will share his experiments of using VS Code for embedded Linux development, which extensions are available to help navigate in the code, build and debug code, from kernel-space and user-space. Talk on Tuesday October 27 at 17:15 GMT.
- Precision Time Protocol (PTP) and Packet Timestamping in Linux. Antoine Ténart has implemented PTP support in both an Ethernet switch driver, and an Ethernet PHY driver, both in the upstream Linux kernel. He will share his experience about PTP, its support in Linux, and its offloading at the MAC and PHY level. Talk on Tuesday October 27 at 19:30 GMT.
- Supporting Hardware-Accelerated Video Encoding with Mainline. After working on the HW-accelerated video decoding on Allwinner platforms as part of our crowdfunded effort, Paul Kocialkowski recently worked on HW-accelerated video encoding on Rockchip platforms. In this talk, he will share the issues encountered, and what needs to be resolved to create a useful kernel to userspace interface to properly support stateless video encoders. Talk on Wednesday October 28 at 16:15 GMT.
- Understand ECC Support for NAND Flash Devices in Linux. Miquèl Raynal, the Linux kernel NAND subsystem maintainer, has recently worked on improving support for various strategies to handle ECC for NAND flash devices. He will share some background information on ECC, why they are needed, how and where ECC are typically handled, and how the Linux kernel deals with the different possibilities. Talk on Wednesday October 28 at 18:30 GMT.
In addition to contributing talks, Bootlin CTO Thomas Petazzoni is also a member of the ELC-E program committee: he reviewed, ranked all talk submitted for the conference and participated with the rest of the committee to the selection of the talks that are now scheduled for the event.
Even though we once again won’t have the chance to meet our fellow members of the embedded Linux community in person, we look forward to attending a set of great talks, and have interesting discussions during the Q&A and through the instant messaging platform that will be available around the conference.
Bootlin has been a participant at the Embedded Linux Conference for many years, and despite the special conditions this year, we will again be participating to this online event, from June 29 to July 1.
- Bootlin engineer Alexandre Belloni and Bootlin’s audio expert will give a talk ASoC: supporting Audio on an Embedded Board, which presents how audio complex in embedded devices are typically supported by the Linux kernel ALSA System-on-Chip framework. This talk takes place on June 29 at 2:05 PM UTC-5.
- Bootlin engineer and CTO Thomas Petazzoni will give his usual Buildroot: what’s new ? talk, giving an update on the latest developments and improvements of the Buildroot project. This talk takes place on July 1 at 11:15 AM UTC-5.
- The vast majority of the Bootlin engineering team will be attending many of talks proposed during the event. Bootlin has been offering to all its engineers the participation to two conferences a year: with the Embedded Linux Conference going virtual, we’ve simply allowed all our engineers to participate, with no restriction. This is part of Bootlin’s policy to ensure our engineers stay as up to date as possible with embedded Linux technologies.
- Bootlin CTO Thomas Petazzoni was once again part of the program committee for this edition of the Embedded Linux Conference, as part of this committee he reviewed and selected the different talks that were submitted.
We are interested in seeing how this virtual version of the Embedded Linux Conference will compare to the traditional physical event. For many old timers to these conferences, the most useful part of a conference is the hallway track and all the side discussions, meetings and dinners with members of the embedded Linux community, and a virtual version makes such interactions more challenging.
In any case, we hope you’ll enjoy the conference! Don’t hesitate to join us in the Q&A session after our talks, or on the 2-track-embedded-linux room of the Slack workspace set up for the event by the Linux Foundation.
This week-end takes place one of the biggest and most important free and open-source software conference in Europe: FOSDEM. It will once again feature a very large number of talks, organized in several main tracks and developer rooms.
Bootlin CTO Thomas Petazzoni will participate to the FOSDEM conference, of course attending many of the talks from the Embedded, Mobile and Automative Devroom, to which he participated to the talk review and selection. Do not hesitate to get in touch with Thomas if you want to discuss career or business opportunities with Bootlin.
In addition, Thomas will also participate to the 3-day Buildroot Developers meeting which takes place in Brussels right after the FOSDEM conference, kindly hosted by Google. During 3 days, some of the core Buildroot developers will work together to discuss the future of Buildroot, as well as review and discuss pending patches and proposals.
