Bootlin at the ARM Kernel Summit, the Embedded Linux Conference and the Buildroot Developers Meeting

Late october will be a busy moment for all the embedded Linux developers meeting in Edinburgh, UK. The Linux Foundation is organizing a number of conferences here, including the Embedded Linux Conference Europe (October 24-25) and LinuxCon Europe (October 21-23), and many co-located other events.

Bootlin will be present at several of these events:

First, three Bootlin engineers will be present at the ARM kernel summit on October 22nd and 23rd. The ARM kernel summit is an invitation-only conference, organized in relation with the Linux Kernel Summit. Gregory Clement, Maxime Ripard and Thomas Petazzoni, engineers at Bootlin have been invited due to their participation to the ARM support in the kernel, mainly on Allwinner SOCs for Maxime and on Marvell SOCs for Gregory and Thomas. Being present at this event is an excellent opportunity to be part of the discussion that shapes the future of ARM support in Linux, and strengthen our relations with other members of this growing community.
Then, the entire technical team of Bootlin will attend the Embedded Linux Conference, on October 24th and 25th. Several talks will also be given by Bootlin engineers:
- On Thursday, 24th October at 11:40 AM, Thomas Petazzoni will give a talk titled Device Tree for dummies!, which will give an introduction to the Device Tree on ARM: what it is, how it is compiled, how it used by the kernel, how Device Tree bindings are defined, how drivers are affected by the Device Tree, etc.
- At the same time in another room, Michael Opdenacker will lead a Bird of a Feather session dedicated to Small Businesses in the embedded Linux world. Exchanging experiences, networking with other companies working in the same field, etc.
- Still on Thursday, at 3 PM, Gregory Clement will give a talk on the Linux kernel Common Clock Framework, which will be an updated version of the talk he gave at ELC earlier this year.
- On Friday, 25th October at 9:30 AM, Thomas Petazzoni will be part of the keynote panel session dedicated to a discussion on Embedded Linux build systems together with Tim Bird (Sony Mobile), Ross Burton (Intel), and Karim Yaghmour (Opersys), the panel being moderated by Jeff Osier-Mixon (Intel).
On Saturday 26th and Sunday 27th October, the Buildroot community is organizing its traditional Developers Meeting, to which Thomas Petazzoni will participate. Some of the core Buildroot developers will join for two days of discussion and work to improve this embedded Linux build system.

As you can see, this will be a very interesting and busy week, and we’re all looking forward to meeting more embedded Linux developers and learning about the latest technologies in this field.

Bootlin at Kernel Recipes, September 2013, Paris

Kernel Recipes conference logo For the second year, a company called Hupstream, located in Paris, is organizing in France a conference fully dedicated to kernel development: Kernel Recipes (French), on September 24th and 25th.

While we at Bootlin couldn’t participate to last year edition, it looked like a very interesting conference, with both useful talks and an audience grouping a significant number of kernel developers and companies interested in kernel development in France. So this year, we are very happy to participate to this conference:

Our CTO and engineer Thomas Petazzoni will be giving one talk about support for ARM processors in the Linux kernel (French), scheduled on Wednesday 25th at 10:00 AM, and he will also be giving a short lightning talk about using Buildroot for kernel developers (French).
In addition to Thomas, Bootlin CEO Michael Opdenacker will be present throughout the conference.

We are definitely looking forward to meeting some of the French kernel developers we have been in contact with over the last months (see the list of participants). It is also worth mentioning that Bootlin has an open position for a kernel or embedded Linux engineer, and that this conference is a great opportunity to meet us!

Bootlin at Linux Plumbers 2013, September 2013, New Orleans

Linux Plumbers conference logo The Linux Plumbers conference has been running since quite a few years now, and has established itself as an important event for the Linux community that takes care of the low-level aspects of the Linux system: the kernel of course, but also the related userspace low-level components. It was originally the primary goal of this conference: get the userspace developers of the low-level components and the kernel developers to meet together. Nowadays, Linux Plumbers is organized as both a set of regular talks and a set of half-day mini-conferences.

The 2013 edition will be held from September 18th to September 20th in New Orleans, United States, and will cover a wide range of topics: ACPI, power management, PCI, Android, Graphics, Automotive, Boot and Core OS, File and Storage systems, LLVM, Network virtualization, Scaling, Secure Boot, Virtualization and more.

As part of Bootlin strong engagement in the community, and continuous effort to ensure its engineers are up-to-date with the latest Linux developments, our engineer Maxime Ripard will attend this conference. For those attending the conference, do not hesitate to meet Maxime, who has an interesting Android experience to share thanks to the Android training course he created at Bootlin, as well has a nice ARM kernel development experience as the maintainer of the Linux kernel support for the Allwinner ARM processors.

Videos of the Embedded Linux Conference Europe 2012

With the approaching Embedded Linux Conference, to be held February 20-22 in San Francisco, we felt that it was time to finally fight with ffmpeg/libav and get the videos we had taken from the last Embedded Linux Conference Europe talks, encode them and publish them online. So here they are, as what we could consider a late Christmas gift.

There are so many talks that it might be hard to watch everything. So I’d like to share with you my preferred talks from this last ELCE (of course, I haven’t been able to see all talks, but only a third of them, so the following selection is only taken from the talks I have seen) :

For sure, the talk I have preferred is the Understanding PREEMPT_RT (The Real-Time Patch) talk from Steven Rostedt (Redhat). In an hour, Steven explained some very interesting internals of PREEMPT_RT, in a very clear way. Definitely a must see, in my opinion.
I also enjoyed the ARC Linux: From a Tumbling Toddler to a Graduating Teen talk from Vineet Gupta (Synopsys). While talking about a specific new CPU architecture that probably most of us have never used, Vineet is able to tell a very nice story by bringing you through various issues they had while porting Linux on this new CPU architecture, giving interesting and funny technical details in the process.
The talk about Regmap: The Power of Subsystems and Abstractions from Mark Brown (Wolfson Microelectronics) was also very good, in that it clearly explained the need for this new kernel subsystem, how the API works, etc. Definitely the kind of talk I’d like to see about more kernel subsystems: in an hour, you learn the philosophy of the subsystem, why it’s there, how it has been designed to solve the original problems, and the basics of its APIs. It’s often what’s missing from an API documentation: the philosophy behind it. Hour long talks that are capable of conveying this philosophy are therefore highly useful.
As usual, David Anders talk, this time about Board bringup: you, me and I2C has been very nice as well. It is a good introduction about electronics related to I2C, it doesn’t go very far for anyone having an existing experience of I2C, but is indeed a very good introduction for those who don’t. I really enjoyed the good explanation about pull-up resistors.
Finally, another talk that was great is Samuel Ortiz (Intel) talk about Near Field Communication with Linux. A bit like the Regmap talk, the great benefit of Samuel talk is that in an hour, he went through the different hardware available for NFC in Linux, the architecture of the software stack, the different software components that exist, their strenghts and weaknesses and so on. So without any prior knowledge about NFC, you get at the end of the talk a very good coverage of how this technology is supported by Linux today.

Videos of the Embedded track at FOSDEM 2012

Better late than never: we finally found the time to update our video encoding scripts, and therefore encode and upload the videos we had taken of the embedded track at FOSDEM 2012. Amongst many other interesting talks, you’ll notice two talks given by Bootlin engineers: one by Maxime Ripard on the IIO subsystem, a kernel subsystem for Industrial I/O devices, and another by Thomas Petazzoni about the usage of the Qt framework for non-graphical applications in embedded Linux systems.

Bootlin at the Libre Software Meeting

In a previous post, we detailed all the talks of the Embedded Systems and Open Hardware track of the Libre Software Meeting, taking place in Geneva in early July.

Bootlin will have a quite important presence at this event, with three talks and one tutorial given by Bootlin engineers. You’ll find below the descriptions of the talks given by Bootlin. Both my colleague Maxime Ripard and myself will be present at Libre Software Meeting, and we will be happy to meet you there to discuss Embedded Linux and Android topics!

A look through the Android Stack

Android has established itself in the past years as a major player in the mobile market, outperforming any other mobile systems.

To do so, Google relied both on well established open-source components, such as the Linux Kernel, and munching them together in a brand new userspace environment. This talk will detail the most important components of Android userspace and the interactions between them that allow developers to face a consistent API for their applications.

This talk will be given on Tuesday 9th July 2012, at 14:00, by Maxime Ripard, embedded Linux and Android engineer at Bootlin. Maxime is also teaching our newest training course on Android system development.

Buildroot: a nice, simple and efficient embedded Linux build system

Started in late 2001 by uClibc developers, Buildroot has grown over its 10 years history from a testing tool for the uClibc C library to a complete, vendor-neutral, embedded Linux build system. Until early 2009, the project was mostly unmaintained and the quality slowly decreased, frustrating many Buildroot users. Fortunately, since early 2009, Peter Korsgaard took over the maintainership of Buildroot, and the project has considerably evolved since then: stable releases are published every three months, the user and developer community has grown significantly, the existing features have been cleaned up, many other new features have been added, the project is no longer uClibc-specific and the quality has been vastly improved. Buildroot now offers a nice, simple and efficient mechanism to build small to medium sized embedded Linux systems, such as the ones found in many industrial systems or highly dedicated systems. Many users are amazed about how easy it is to get started with Buildroot, especially compared to other build systems. This presentation will show how Buildroot can be used to build embedded Linux systems, highlighting the new features and improvements made over the last few years, and detailing how the simplicity of Buildroot allows you to focus on developing the applications for your system. A quick overview of the future Buildroot developments will also be provided.

This talk will take place on Wednesday 10th July at 17:00 and will be given by Thomas Petazzoni, embedded Linux engineer at Bootlin, and long time Buildroot contributor.

Linux kernel on ARM: consolidation work

In Spring 2011, Linus Torvalds asked the ARM Linux maintainers to clean up the contents of arch/arm/ in the Linux kernel code by doing more consolidation between ARM sub-architectures.

More than a year later, a lot of work has been accomplished in this area, especially thanks to the introduction of the device tree for the ARM architecture, the pinctrl subsystem and the clock framework into the Linux kernel.

Through this talk, we will present the challenges the ARM architecture creates in terms of Linux kernel support, and then describe from a technical point of view how the device tree, the pinctrl subsystem and the clock subsystem work and how they can improve the consolidation between different ARM sub-architectures.

The talk will be designed to be accessible to an audience having only a moderate knowledge of kernel programming and internals, and will therefore provide enough context for such audience to understand the issues that those different mechanisms are striving to solve.

This talk will take place on Thursday 11th July at 10:00 and will be given by Thomas Petazzoni, embedded Linux engineer at Bootlin.

Tutorial on using Buildroot, a nice, simple and efficient embedded Linux build system

This workshop follows the Buildroot presentation proposed in the same topic. During one half-day participants will be introduced on how to efficiently use Buildroot for their own projects:

Basic usage of Buildroot: generate the first system, boot it on a hardware platform
Add packages to Buildroot
Customize Buildroot for real-life projects: how to integrate project specific patches, configuration and customization

Participants are invited to come with their own laptop, installed with a sufficiently recent GNU/Linux distribution. Participants are recommended to attend the Buildroot talk by the same speaker before attending the workshop, as the talk will give an overall introduction on Buildroot.

This tutorial will take place on Thursday 11th July from 14:00 to 17:00 and will be given by Thomas Petazzoni, embedded Linux engineer at Bootlin, and long time Buildroot contributor.

Embedded Linux Conference 2012 videos

The 2012 edition of the Embedded Linux Conference took place on February 15-17th 2012 at Redwood Shores near San Francisco in California. Three engineers of Bootlin attended this conference, and we reported every day our impressions about the talks, see our blog posts for day 1, day 2 and day 3. We have now taken the time to encode all the videos we have recorded during this event, and are proud to distribute them today.

It is worth noting that for the first time, the Linux Foundation was also recording videos of the talks, the Linux Foundation videos are available from video.linux.com, and we included links to these videos below for the different talks.

We hope that those of you who couldn’t attend the conference will enjoy those videos, with many great talks on technical embedded Linux topics.

Android Builders Summit 2012 videos

On February 13-14th 2012, the second edition of the Android Builders Summit took place in Redwood Shores, near San Francisco in California. While Bootlin was not officially in charge of video recording for this conference, we recorded the talks we attended and that we are glad to share below. The Linux Foundation has also recorded those talks (except a few of them for which they had technical issues), and we provide those additional links below. You can also follow our reports from day 1 and day 2 of this conference.

You’ll find below our videos of the main talks we recorded, and also the videos of the lightning talks that took place on the evening of the first day of the conference. Enjoy!
