rusty: Add debug! logging to load_balance.rs
We removed the debug!() output that was previously present in main.rs. Let's
add more debug!() output that helps debug the current LB hierarchy.

SCHED_EXT SCHEDULERS

Introduction

This directory contains the repo's schedulers.

Some of these schedulers are simply examples of different types of schedulers that can be built using sched_ext. They can be loaded and used to schedule on your system, but their primary purpose is to illustrate how various features of sched_ext can be used.

Other schedulers are actually performant, production-ready schedulers. That is, for the correct workload and with the correct tuning, they may be deployed in a production environment with acceptable or possibly even improved performance. Some of the examples could be improved to become production schedulers.

Please see the following README files for details on each of the various types of schedulers:

  • rust describes all of the schedulers with rust user space components. All of these schedulers are production ready.
  • c describes all of the schedulers with C user space components. All of these schedulers are production ready.

Note on syncing

Note that there is a sync-to-kernel.sh script in this directory. This is used to sync any changes to the specific schedulers with the Linux kernel tree. If you've made any changes to a scheduler in please use the script to synchronize with the sched_ext Linux kernel tree:

$ ./sync-to-kernel.sh /path/to/kernel/tree
