When selecting an idle CPU for a task that has been woken up, prioritize reusing the same CPU if the waker and wakee share the same L3 cache. Otherwise, attempt to migrate the wakee to the waker's CPU, provided it is allowed by the wakee's scheduling domain. This seems to consistently improve FPS performance when the system is not operating over its full capacity. Example: $ __GL_SYNC_TO_VBLANK=0 vblank_mode=0 glxgears -geometry 800x600 - before: ~18305.77 FPS - after: ~19060.62 FPS Signed-off-by: Andrea Righi <andrea.righi@linux.dev> |

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.
