Bootlin back from Kernel Recipes!

As announced previously, we participated to the Kernel Recipes conference in September in Paris. Three people from Bootlin attended the event: Grégory Clement who gave a talk about SD/eMMC, Boris Brezillon and Mylène Josserand.
Unfortunately, we were not able to attend the Embedded Recipes conference but we hope to catch up next year!

Overview of SD/eMMC, their high speed modes and Linux support, by Grégory Clément

Here is the video of Grégory’s presentation:

You can find the slides on our website.

KernelShark 1.0; What’s new and what’s coming, by Steven Rostedt – VMware

The first day, one of the most enjoyable talk was “KernelShark 1.0; What’s new and what’s coming”. One reason is the speaker itself, Steven Rostedt, who is very experienced in presenting. He always knows very well the approached subject and does a few jokes during the talk: all of these lead to a very pleasant talk.

From my point of view, the talk itself presents two interesting subjects: the process of developing a tool’s front end (with trace-cmd being the example) and then a presentation of this GUI.

Atomic explosion: evolution and use of relaxed concurrency primitives, by Will Deacon – ARM

On the second day, Will Deacon talked about an interesting topic “Atomic explosion: evolution and use of relaxed concurrency primitives”. As usual with Will, the technical level is high and seeing the video a second time is recommended to really put the multiple pieces of information together.

Besides the explanations on the atomic operation and their meaning from the point of view of the CPUs, Will also presented his new API, how and when we should use it.

Coccinelle: 10 Years of Automated Evolution in the Linux Kernel, by Julia Lawall – INRIA/LIP6

Happy birthday, Coccinelle!
It has been 10 years that this project is helping kernel developers to track bugs or clean the kernel up. For this event, Julia did a retrospective and a “what’s new” of this project.

Initially used only by Coccinelle developers, it was quickly adopted by all the kernel community. It was interesting to have the history, feedback and also updates on this project that is more and more used now.

Meltdown and Spectre: seeing through the magician’s tricks, by Paolo Bonzini – Red Hat

Paolo Bonzini did a great presentation about Meltdown and Spectre with a detailed description of the different mechanisms taken advantage of by these two issues: branch prediction, memory mapping, paging, etc.
It was a great overview and well explained.

The end word

As usual at Kernel Recipes, Frank Tizzoni is in the room to draw sketches of attendees and speakers! Have a look at all the sketches! Some of them are really funny 🙂

It is the first time we attended the Kernel Recipes and this conference is as good as the feedback we received from people who were in the previous editions.
The major points are the high quality of the talks, the interaction between the speaker and the audience but also the social events around it.

Boris and Grégory

It is the second time that I attended Kernel Recipes and I am still convinced that this conference is really nice.
The talks, the audience, the format (limited to 100 people) and all social events are great!
My only regret is that I was not able to attend Embedded Recipes to enjoy a bit more the ambiance around these two conferences.
I hope to register in time next year! 😉
