And if anyone wants the slides:

(video recordings will appear a bit later)

So PSA we are now not allowed to add Link: tags anymore unless they add information that is not in the commit message. @axboe has the receipts.

It's ok apparently to add a link to the merge message of a Multi-Patch series.

Might want to start spreading that word...

Suggestion for the week-end: Open Source Summit Europe 2025 video binge watching.

The Linux Foundation has just released all the videos they took at the OSS EU 2025 conference in Amsterdam. They are so many of them that they are hard to count!

So, now you can attend OSS EU 2025 and the Embedded Linux Conference Europe 2025 free of charge, or if you attended, you can watch the many interesting talks that you missed.

Thanks to Ross Burton for sharing the news!

Recording (https://www.youtube.com/watch?v=O8Q8nIzEG6c ) and slides (https://static.sched.com/hosted_files/osseu2025/b3/pdx86-community-health-2025.pdf ) from Hans de Goede's #OSSEU25 talk "Creating a Healthy Vibrant [#Linux] #Kernel Subsystem Community" are now online.

From the abstract: "End 2020 I became the maintainer of the drivers/platform/x86 (pdx86) kernel subsytem. The subject of this talk is my experience in creating a friendly welcoming environment, growing the pdx86 community and how this helped me to avoid burnout by being able to delegate to community members."

Wild, it seems that a odd number of cores is a problem

It seems like for the past few weeks my phone (Pixel 8) consistently fails Anibus on lore. Anyone else having issues? No problem on my actual computer which is more important use case.

@jmorris @pdp7 unfortunately not, I'm already boarded to fly home. Hope the final day goes great!

Thanks to everyone for a great week of Linux in Amsterdam!

Hello AMS! Arrived just in time for the start of Embedded Linux Conf. "Why Won't My CPU Sleep? Debugging CPUIdle Mysteries on ARM SoCs" by @khilman of BayLibre and Dhruva Gole of TI:

Except speaking on Open Source Summit Europe (OSSE) 2025, I will also participate in Speaker Office Hours on Wednesday 10:30 AM: https://sched.co/27flt

Happy to answer some questions regarding first Linux kernel contributions, Embedded Linux Kernel, ARM64 laptops (yep, I am daily using Lenovo T14s with Qualcomm X1E SoC), Devicetree bindings / DTS or why your last patchset was not merged. :)

I once again ask you to please stop using gmail for mailing lists.

Attached is a screenshot of *just one* of the 4 nodes delivering various kernel mailing list traffic with a deferred queue of 100,000+ messages, all for gmail.

We are currently sitting on about 500,000 deferred messages, all for gmail. I am very, very close to just banning gmail addresses from large lists.

Looks like the risc-v community is learning from history! Hopefully this results in more upstream development efforts: https://riscv.org/blog/2025/07/risc-v-upstreaming/

There will be a Devicetree Microconference on Linux Plumbers in Tokyo, covering wide range of topics for Devicetree-based systems. The Call For Proposals is still open and you can submit your talk choosing "Devicetree MC" as the track. More details with examples of topics (not limited to these!): https://lpc.events/event/19/contributions/2008/

All microconferences (MCs) at LPC 2025 have been accepted! It is time to submit topics to your favorite MCs.

Please check out our latest blog post for the list of MCs, and how to create a ideal MC topic.

That talk is incredible. If you're into hardware in general, you should watch it.

Meet our awesome mascot in the colors of the 2025 edition!
Bringing that unmistakable French touch to the conference.:)

Feel free to download and use them – and keep an eye out, you might just spot them on some slides this September!

Open Source Summit Europe 2025 is coming (in August)!

I will speak about two Linux kernel topics on introductory level, so if you want to learn something practical about Devicetree or using static analysis during development in Linux kernel then please come or watch online.

If you want to come and ask questions just find me around the hall or after the talks. We can also organize Unconference Session if there are more Devicetree topics.

1. DTS 101: From Roots To Trees, Aka Devicetree for Beginners
https://sched.co/25Vsl

2. Between Building and Testing Your Linux Driver
https://sched.co/25VoV

Happy 2π day to those who celebrate it!

The first talk of the conference is Kees Cook @kees on 10 years of the Kernel Self Protection Project (KSPP).
