ELC 2011 videos

The Embedded Linux Conference 2011 took place between April, 11th and April, 13th in its now usual place, the Kabuki hotel in San Francisco, California. It was the first edition organized since the merge of the CE Linux Forum into the Linux Foundation. During three days, three parallel tracks of talks and BoFs about technical topics around embedded Linux : kernel support, power management, build systems, file systems, real-time, and more.

As usual, part of the Bootlin team was at this Embedded Linux Conference, in order to keep up with the latest developments from the embedded Linux community. Gregory Clement (left on the picture), Maxime Ripard (right on the picture) and myself (center on the picture) were present, and we recorded all talks of the conference. And just a little bit more than one month later, we are ready to announce that all videos are now available online, in 1080p high-definition, and in a lower 450p resolution, encoded with the new VP8 codec.

Amongst all the conferences below, each of us have selected the three ones we thought were the most interesting ones (note that the top three for each us is necessarily composed of distinct talks, as none of us have seen the same talks since we had to record talks from three different sessions in parallel) :

  • For Gregory Clement, the top three is: Yoshiya Hirase talk about Faster Resume For More Energy Savings on MeeGo, Arnd Bergmann talk about Optimizations For Cheap Flash Media (which follows Arnd article on the same topic in LWN) and a set of three related talks about the video infrastructure in the Linux kernel, that Gregory recommends to watch in this order: Media Controller Framework (MCF) For OMAP2+ Display Subsystem (Sumit Semwal), Video4linux: Progress, New videobuf2 Framework and the Future (Hans Verkuil) and Bringing up HDMI Display for OMAP4 Panda Board – Design, Challenges and Lessons Learned (Mythri pk).
  • For Maxime Ripard, the top three is: John Stultz talk about Android for servers, Mike Anderson talks about ARM NEON and GPU programming, Wolfram Sang talk about Helping the process
  • For myself, the top three is: Jesse Barker talks about the ARM Graphics ecosystem which gives a nice overview of the state of this topic, Hai Shalom talk about PCD (which is an original and interesting replacement for init), Dave Stewart talk about The Yocto Project and its Application Development Toolkit (because it gives details on how Yocto is supposed to be used for application development, a topic I’m interested in as a Buildroot developer)

It is also worth noting that this Embedded Linux Conference was co-located with the first edition of the Android Builders Summit, for which we will soon publish videos as well. The next embedded Linux conference will take place in Europe, in Prague from October 26th to 28th, co-located with the first edition of LinuxCon Europe and just after the Kernel Summit. Prague will really be full of Linux developers during this end of October, it’s time to book this week on your agenda as well !

Videos from the FOSDEM 2011 Embedded track

As every year, FOSDEM, the largest community-driven open source conference in Europe, took place early February in Brussels. And again, Bootlin was around with its HD camcorder, to record the conferences of interest for embedded developers. They are now available for download!

Videos from Libre Software Meeting 2010 in France

RMLL 2010The Libre Software Meeting (Rencontres Mondiales du Logiciel Libre in French) is a community-driven event that takes place every year in France, and covers a wide range of topics in the free and open source software domain. Each year, an Embedded systems and free hardware topic is proposed, which in 2010 was lead by Florian Fainelli, Pierre Ficheux and myself.

While most of the talks took place in French, a few talks were given in English and as we recoded videos from those talks, we thought it’d be a good idea to highlight them to the english readers of our blog. We found it especially important since amongst those videos, there are two particularly interesting presentations from Sarah Sharp, a kernel developer from Intel, about USB3 and its support in Linux. As usual, all our videos are published under the Creative Commons Attribution – ShareAlike Licence version 3.0 license.

Bootlin at the Embedded Linux Conference and Android Builders Summit

In just two weeks from now, the Embedded Linux Conference will start in San Francisco, followed by the Android Builders Summit, at the usual Hotel Kabuki location, where the conference is taking place for the third consecutive year.

Embedded Linux Conference 2011

The program of the Embedded Linux Conference has been announced recently, and as usual, features a wide set of technical embedded Linux talks:

  • Filesystem/storage: Power Fail Safe FAT File System, Optimizations For Cheap Flash Media, from Arnd Bergmann, who has also recently published a very interesting article on the same topic.
  • Power management: Faster Resume For More Energy Savings on MeeGo, Powerdebug(ging): A Linaro Perspective, How to Power Tune a Device Running on a Linux Kernel for Better Suspend Battery Life, The Evolution of Tracing and Profiling for Power Management and Accelerators, Runtime PM: Upstream I/O Device Power Management
  • Real-time: Solving Real-Time Scheduling Problems with RT_PREEMPT and Deadline-Based Scheduler, Real-time Audio on Embedded Devices, Identifying Embedded Real-Time Latency Issues: I-Cache and Locks
  • Build system, with a huge number of Yocto-related talks, but no other build systems represented: State of OpenEmbedded Internal Toolchain and SDKs, Yocto Project: Practical Kernel Development Tutorial, Building Custom Embedded Images with Yocto, The Yocto Project and its Application Development Toolkit (ADT) – The Answer to Effective Embedded Application Development, Yocto Project Community BoFs, Delivering Predictability: The Yocto Project Autobuilder, Automated Sanity Testing, License Collection, and Build Statistics Tracking
  • Multimedia: Fun with QML and JavaScript, Integrating a Hardware Video Codec into Android Stagefright using OpenMAX IL, Media Controller Framework (MCF) For OMAP2+ Display Subsystem, Video4linux: Progress, New videobuf2 Framework and the Media Controller, Bringing up HDMI Display for OMAP4 Panda Board – Design, Challenges and Lessons Learned, Linux Graphics Meets the ARM Ecosystem
  • FPGA: Dynamic Co-simulation of FPGA-based Linux Systems-on-Chip, A High Performance Interface Between the OMAP3 and an FPGA
  • Networking: What Embedded Linux Developers Should Know About IPv6, Zigbee Networking & Linux
  • Debugging: Kernel Shark Tutorial and Tools and Techniques for Debugging Embedded Systems
  • Optimization: Snapshot Booting on Embedded Linux, ARM Neon Instruction Set and Why You Should Care, Controlling Memory Footprint at All Layers: Linux Kernel, Applications, Libraries and Toolchain, High-Performance Computing using GPUs, What Are and How to Find a Program’s Unused DSOs
  • Low-level: Board Bringup: Open Source Hardware and Software Tools, Working with HardIRQs: Life Beyond Static IRQ Assignments, Genie in the Bottle: Linux Drivers for the AM1808 PRU
  • And many other talks on various topics: LLVM, Clang and Embedded Linux Systems, Linaro: A Year of Change, Control, Recover and Debug Your Embedded Product with PCD, Developer’s Diary: Helping the Process, High-Level Web Interface to Low-Level Linux I/O on the Beagleboard, Linaro Automated Validation on ARM, Crowd Sourcing and Protecting the Open Source Community, Android for Servers?, Hot Multi-OS Switch: How to run Ubuntu, ChromiumOS, Android at the Same Time on an Embedded Device.

This edition will be the first one organized since the merge between the CE Linux Forum into the Linux Foundation, and will therefore be a great opportunity to see if this merge had any impact on the technical quality of the conference.

My colleagues Maxime Ripard (who joined Bootlin just a week ago) and Gregory Clement as well as myself will be present at the Embedded Linux Conference and the Android Builders Summit, and we will as usual record all talks of both of these conferences and will put them online, as we have done recently for the talks that took place during the Embedded Linux Conference Europe 2010 in Cambridge. Do not hesitate to meet us in San Francisco!

ELCE 2010 videos – Now in full HD

Videos from the Embedded Linux Conference Europe, Cambridge, UK, October 2010

Just a few weeks before the next edition of the Embedded Linux Conference in San Francisco, here are the videos from the previous edition in Europe a few months ago.

These videos took more time to process than expected, because of intense months on our side, but also because of the switch to the VP8 video codec. VP8 is the new Open Source and royalty free video codec, and is a successor to the codec that Theora was derived from. Unlike Theora which is now lagging behind, it is a very close competitor to H264, both in terms of quality and video size.

The switch to VP8 allowed us to release the videos in their original full HD resolution (we now have three full HD camcorders to shoot conference videos), with video files of about the same size.

You will probably need a recent GNU/Linux distribution (such as Ubuntu 10.10) to watch these videos. As this codec released by Google is taking off quickly, you should also find solutions to watch videos on Windows and MacOS X. Don’t hesitate to post comments here about your experience playing these files. You can even watch them on the Panda board, which can decode VP8 with its hardware video decoder.

As usual, these videos are released under the terms of the Creative Commons Attribution – ShareAlike Licence version 3.0.

As often in conferences, the videos were unfortunately shot is tough lighting conditions. The organizers usually turn off the lights to make it easier for the audience to read the screen. The consequence is a high contrast between the speaker and the screen, causing the speaker to appear very dark when we film her or him together with the screen. In a number of videos, we tried to solve this by using a beach mode provided by our camcorders. While the speaker now looks great, this unfortunately blurred the screen, causing more inconvenience than benefits. We gave up this mode in the last videos and will shoot ELC 2011 is the standard way, even if the speaker looks dark again. At least, with full HD videos, you will be able to read the slides directly on the screen.

The videos from the 2010 GStreamer conference will also be available in the next days, and to help you produce your own videos, we will release our new video processing scripts soon too.

Videos from FOSDEM 2010

Peter Korsgaard presenting Buildroot in the Cross build systems workshop at FOSDEM 2010

Like every year, the Free and Open Source Developer European Meeting took place early February in Brussels, and Thomas Petazzoni, from Bootlin, attended and recorded a few talks from the embedded session. However, contrary to previous years, I haven’t been able to record all talks from the embedded session, since I attended talks from other sessions which were already being recorded by others.

We also attended talks from the X.org and Coreboot developer roooms : videos for the X.org developer room can be found at http://video.fosdem.org/2010/devrooms/xorg/ and videos for the Coreboot developer room can be found at http://video.fosdem.org/2010/devrooms/coreboot/.

ELC 2010 videos

Videos from the Embedded Linux Conference in San Francisco, April 12-14, 2010.

The 2010 edition of the Embedded Linux Conference was once again a very interesting event. For embedded Linux developers, the Embedded Linux Conference is a perfect place to learn about new technologies, profit from the experience of other developers, and to meet key software developers.

For people who couldn’t attend this conference, and for single core people who didn’t manage to attend two or three talks at the same time, here are the videos that we managed to shoot. As usual, the videos are released with a Creative Commons Attribution – ShareAlike 3.0 license.

We hope it makes you feel like joining the next edition of the conference. If you can’t wait, what about going to ELC Europe in Cambridge (UK) in late October? It has a very interesting program too. Of course, the sessions will also be recorded. I hope to see you there!

ELC Europe 2010 sessions announced

List of sessions and speakers at ELC Europe in Cambridge, UK

Cambridge, UKBeing a member of the organization committee of the Embedded Linux Conference Europe, I get access to fresh news about this yearly conference. The call for presentations is now over and we have just announced the list of sessions.

Note that this list is not the final one yet. Some speakers haven’t confirmed their participation or haven’t sent their biographies yet. There are also two or three speakers added at the last minute who are not listed yet.

The conference will happen in Cambridge, UK, on October 27-28, 2010. Keep an eye on the website (or on our blog). Registration should open in a few days from now, and all practical details will be given then.

See also the agenda of the GStreamer conference which will happen at the same location on the day before.

Linux device drivers architecture talk at Libre Software Meeting

recursive device modelThomas Petazzoni gave a talk on the Linux kernel architecture for device drivers at the Libre Software Meeting in Bordeaux, France. While the talk was given in French, the materials are in English and can therefore benefit a larger audience. The talk seems to have been well-received, especially from people already having a basic Linux kernel development experience. The topics covered are part of our Linux Kernel development training, and are also usually very appreciated from the trainees already having Linux kernel experience.

The idea of the talk is to give an overview of how device drivers fit into the kernel, both to expose their functionality to upper layers (such as a network device driver exposes itself to the kernel network infrastructure) and to detect/access the hardware using the device/driver model, which is quite hard to understand from the source code only.

The talk went through the following sections :

  • First a basic introduction to device drivers: how devices are seen from userspace applications, and how a simple, raw, character driver can be implemented. It allowed to expose the principle of operations and their similarity with methods in object-oriented programming, and the principle of registration to an upper-layer infrastructure
  • Then, an introduction to what I call « kernel frameworks », i.e kernel subsystems that specialize a general device type (i.e character device) into a particular device type (i.e serial port device, framebuffer device, etc.). The talk illustrates this with the framebuffer core and the serial port core.
  • Finally, an explanation about the device model: bus drivers, adapter drivers and device drivers. I started with the example of the USB bus: being a dynamically-enumerated bus, it provides a good illustration of the device model principles. At the end, I explained how the device model works for the devices embedded into a SoC using the platform drivers/devices mechanism

The slides for this talk are no longer available, but their updates are now integrated in our Linux kernel and driver development training materials which are freely available.
