I gave a talk about my new CPU scheduler, named LAVD. While the recorded audio is not great, I hope it is still understandable.
"Using sched_ext to improve frame rates on the SteamDeck: Ideas behind the LAVD scheduler" in the sched_ext MC at the #linuxplumbers 2024, Vienna.
The Linux Plumbers Conference (LPC) is a developer conference for the open source community. The LPC brings together the top developers working on the plumbing of Linux - kernel subsystems, core libraries, windowing systems, etc. - and gives them three days to work together on core design problems. The conference is divided into several working sessions focusing on different plumbing topics, as well as a general paper track.
Extensible scheduler class, or sched_ext, is hot! I wrote a blog post about the design and architecture of the sched_ext framework. After reading the blog post, you will be able to read and understand each scx scheduler code.

This is the second blog post about the sched_ext, a BPF-based extensible scheduler class. In this blog post, I briefly update what has been happening in sched_ext, then introduce the scheduler architecture and the sched_ext API. After reading this, you should have a good understanding of the sched_ext architecture and be ready to read the source code of any sched_ext schedulers.

You may wonder if a process scheduler is still an interesting topic. Yes, it is indeed hot recently.
One of the most recent advances is making a scheduler extensible with sched_ext, which I am working on at @igalia.
Please learn more in my blog post. This blog post will give you more details about my work and sched_ext, a cool extensible scheduler framework.

This blog post introduces sched_ext, a recently proposed extensible scheduler class. sched_ext allows you to write and run your custom process scheduler optimized for your target workloads and hardware architectures using BPF programs. In the rest of the post, I recap the concept of a scheduler at the high level and go over the default schedulers in Linux kernel. Then, I introduce why an extensible scheduler framework, sched_ext, is necessary, how to use it, and provide a BPF scheduler example.
