Crafting a Linux kernel scheduler in Rust

In the realm of operating systems, the heart of performance lies in the CPU scheduler: a critical component responsible for managing the execution of tasks on a system.
Playing around with CPU scheduling policies has always been a dream for many kernel hackers and OS enthusiasts. However, such material typically remains within the domain of a few core kernel developers with extensive years of experience.
What if we could bring this dream to life and make it really accessible, thanks to sched-ext, eBPF and Rust?

Abstract

In the realm of operating systems, the heart of performance lies in the CPU scheduler: a critical component responsible for managing the execution of tasks on a system.

Playing around with CPU scheduling policies has always been a dream for many kernel hackers and OS enthusiasts. However, such material typically remains within the domain of a few core kernel developers with extensive years of experience.

What if we could bring this dream to life and make it really accessible, thanks to sched-ext, eBPF and Rust?

This talk will cover the design and implementation details of scx_rustland: a fully functional Linux scheduler written in Rust, that runs entirely in user-space.
