Right now, the SCX_WAKE_SYNC logic in rusty is very primitive. We only check to see if the waker CPU's runqueue is empty, and then migrate the wakee there if so. We'll want to expand this to be more thorough, such as: - Checking to see if prev_cpu and waker_cpu share the same LLC when determining where to migrate - Check for whether SCX_WAKE_SYNC migration helps load imbalance between cores - ... Right now all of that code is just a big blob in the middle of rusty_select_cpu(). Let's pull it into its own function to improve readability, and also add some logic to stay on prev_cpu if it shares an LLC with the waker. Signed-off-by: David Vernet <void@manifault.com> |

RUST SCHEDULERS
Introduction
This directory contains schedulers with user space rust components.
The README in each scheduler directory provides some background and describes the types of workloads or scenarios they're designed to accommodate. For more details on any of these schedulers, please see the header comment in their main.rs or *.bpf.c files.
