  sched_ext: a BPF-extensible scheduler class (Part 1)

  18 December 2023 by Changwoo Min

  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.
