Bootlin talks at Open Source Summit Europe 2024: slides and videos

João Marcos Costa giving his talk at Open Source Summit Europe 2024No less than 13 Bootlin engineers attended the Open Source Summit Europe 2024 in Vienna earlier this month, and two Bootlin engineers gave talks at this conference, keeping with Bootlin’s long standing tradition of sharing knowledge with our peers of the broader embedded Linux community.

In this blog post, we’re happy to share the slides and videos of the two talks we have during this event: Linux Power Management Features, Their Relationships and Interactions and Inspecting and Optimizing Memory Usage in Linux

Bootlin at Kernel Recipes 2024

Kernel Recipes 2024Just after the busy week of Open Source Summit Europe and Linux Plumbers in Vienna, the Kernel Recipes conference is starting in Paris, as it takes place on Sep 23-25.

With its single-track format, high-profile speakers, small audience and friendly atmosphere, Kernel Recipes is quite unique in the landscape of open-source conferences, and has therefore become very popular over the past 10 years.

This year again, Bootlin engineers are attending this event, with this year 5 of our engineers participating: Jérémie Dautheribes, Alexis Lothoré, Romain Gantois, Louis Chauvet and Bastien Curutchet.

Do not hesitate to get in touch with the Bootlin engineers at the event to discuss Linux kernel and/or embedded Linux topics!

Bootlin topics at Linux Plumbers conference in Vienna, Sep 18-20

Linux Plumbers conference 2024Next week is going to be a busy week in Vienna, with the Open Source Summit Europe followed by the Linux Plumbers conference. As we had already published in a previous blog post, Bootlin will have a very strong presence at those events: 13 Bootlin engineers will participate to the Open Source Summit and 2 will give talks, and 8 Bootlin engineers will participate to Linux Plumbers.

Regarding Linux Plumbers, we also proposed 3 discussion topics that got accepted:

  • Representing the front-facing ports of Ethernet interfaces, a discussion proposed by Bootlin engineer Maxime Chevallier. This is a topic that Maxime has been working on for quite some time, mainly as part of customer projects at Bootlin. The first step of this effort recently got merged in the Linux kernel, and the ethtool part is being reviewed, but what got merged is only the first step, and additional developments are needed and will be discussed at Plumbers.
  • Runtime hotplug on non-discoverable busses with device tree overlays, a discussion proposed by Bootlin engineers Luca Ceresoli and Hervé Codina. Both Luca and Hervé have been working over the past year or so on projects that involve using Device Tree overlays. Luca on a project where a part of the hardware, with non-discoverable busses (I2C, DSI, etc.) is connected/disconnected at runtime, and Hervé on a project where a PCI device is a full SoC with numerous peripherals that already have drivers in the kernel. Several patch series have been proposed on the mailing lists already, and we hope this discussion at Plumbers will help move the topic forward.
  • Hotplug DRM pipeline components on non-discoverable video busses, a discussion proposed by Bootlin engineer Luca Ceresoli is also related to the previous project, but this discussion focuses on the DRM aspect. Indeed, one of the non-discoverable bus that gets connected/disconnected in our use-case is DSI, so we need to make it hotpluggable, which isn’t supported by Linux currently. We made some proposals on the mailing lists on this topic, and discussion is on-going. We hope a face to face discussion at Plumbers can help moving this other topic forward.

Meet us next week in Vienna, either at the Open Source Summit and/or at Linux Plumbers!

Bootlin at Open Source Summit Europe and Linux Plumbers in Vienna, Sep 16-20

On the week of September 16-20, Vienna is going the place to be for all open-source developers, with a large number of conferences taking place during this week. Being strong contributors to several key open-source projects, Bootlin will be strongly present at those conferences.

Open Source Summit Europe 2024

Open Source Summit Europe will take place on Sep 16-18, and its schedule has recently been published. This year, the Embedded Linux Conference part of this conference is unfortunately reduced to just 2 tracks of 2 days, but we nevertheless hope to see some interesting topics. Bootlin has contributed and will contribute to this event with:

In addition, no less than 12 Bootlin engineers will participate to this Open Source Summit Europe: Alexandre Belloni, Grégory Clement, Hervé Codina, João Marcos Costa, Kamel Bouhara, Louis Chauvet, Miquèl Raynal, Richard Genoud, Théo Lebrun, Thomas Petazzoni, Thomas Perrot and another engineer who will join our team just in time before the event to be part of the trip.

Linux Plumbers 2024Right after the Open Source Summit, we will also be present at the Linux Plumbers conference. We have already submitted a few topics in various micro-conferences, and we’re hoping to see them accepted. Regardless of that, 8 engineers from our team will be attending Linux Plumbers: Hervé Codina, Louis Chauvet, Luca Ceresoli, Maxime Chevallier, Miquèl Raynal, Théo Lebrun, Thomas Petazzoni, Thomas Perrot.

We look forward to meeting the community, presenting our projects and ideas and learning about the work done by others! See you all in Vienna in September!

Back from the Embededded Linux Conference: selection of talks #1

As we wrote in a previous blog post, 11 engineers from Bootlin attended the Embedded Linux Conference in Seattle in April. We have a tradition after such an event to share with you a selection of talks that we have found useful. In order to achieve this, we ask each of our engineers who participated to the conference to pick one talk they would like to highlight, and write a short summary/feedback about the talk. In this first installment of this series of blog posts, we’ll share our selection of 4 first talks.

Bootlin engineer Louis Chauvet at Linux Display hackfest

2024 Display Next HackfestFrom May 14 to May 16, Igalia is organizing the 2024 Display Next Hackfest, an event where talented developers will gather to explore the latest technologies and trends in the Linux Display Stack.

As explained on the event website:

It has an unconference format where participants propose topics for presenting, roadmapping, discussing and examining together. It aims to unblock bottlenecks, design solutions, raise pitfalls and accommodate the needs of each layer of the display stack. Participants should feel free to propose any topic which interests them. Some topics from the previous edition include: HDR and color management, frame timing and variable refresh rate (VRR), atomic flips, testing and CI, etc.

Bootlin engineer Louis Chauvet, who has started contributing to the Linux kernel VKMS driver, and is starting to work on IGT and the latest version of the Chamelium CI testing hardware, will participate to this hackfest, together with many developers from Igalia, Redhat, Intel, Google, RaspberryPi, AMD, ARM, Collabora and more. This will allow us to discuss current developments and topics, and meet the relevant developers of the Linux graphics/display community.

Our talks at Embedded Open Source Summit 2024

Bootlin at Open Source Experience and SIDO in Paris, Dec 6-7

Paris will be hosting next week-end a combined event composed of the Open Source Experience and SIDO, the first dedicated to open-source technologies, and the second to IoT, AI, digital infrastructure and cybersecurity.

Open Source Experience

Thomas Petazzoni, Bootlin CEO, will be representing Bootlin at these events, and will also be participating to the round table Embedded systems security: a technical and organizational approach on December 7, at 2:30 PM UTC+1. The abstract of the round table is:

Security is a major issue. Embedded systems are increasingly complex and connected, making them more vulnerable. The aim of this round table is to discuss best practices for guaranteeing security

Thomas will be speaking with Daniel Fages (Freelance), Eloi Bail (Savoir Faire Linux) and Jean-Charles Verdié (Canonical), and the round table will be moderated by Cédric Ravalec (Smile).

If you’re interested in discussing career, business or partnership opportunities with Bootlin, do not hesitate to contact Thomas Petazzoni ahead of the event to schedule a meeting.
