Really proud to see the "sched_ext deadline server" landing upstream in Linux v7.0.
This is a big milestone for sched_ext, as it allows custom CPU schedulers to coexist with real-time tasks, making them viable for embedded & other real-time scenarios.

If you are attending LPC in Tokyo, you are welcome to join the sched_ext microconference tomorrow (Fri 12/12) at 3pm. We will cover recent developments, current status and upcoming features in the sched_ext framework.
Where: Hall B2
Schedule: lpc.events/event/19/ses...
The most noticeable feature is MCP server support, enabling AI agents such as Claude, Cursor, etc. to automate kernel development workflows, from quickly running commands/scripts inside rebuilt kernels to even performing automated bug bisection.

As a hobby project I put a neural network in the Linux kernel scheduler using sched_ext and it actually works, at least for the workload it was trained on. :)

virtme-ng v1.38 is out! This is a pretty stable update, bringing only bug fixes. Most notably, the infamous "Stale file handle" errors with virtiofsd are finally gone. If you've hit them before, you know how annoying they were, so time to update!

It was a great honor to speak at @kernelrecipes.bsky.social again this year. This conference is always a rich source of inspiration, I'm going back home full of new ideas... and lots of work to do. :)
To all kernel folk: don't miss it next year! #kr2025
Video of my opening talk at the sched_ext microconference (LPC 2025), discussing open issues and future directions for sched_ext: deadline server, hierarchical schedulers, and built-in scheduler improvements.

That was cutting-edge! ⚙️
Thanks to Andrea Righi for exploring how AI-driven logic and Rust can make kernel scheduling more intelligent.
