Changwoo Min 24a238846e scx_lavd: optimizing deadline related tunables
The competition window was 7.5 msec, half of the targeted latency.
However, it is too wide for some workloads, so unrelated tasks may
compete with each other. Hence, it is tightened to about 1 msec with
LAVD_LAT_WEIGHT_SHIFT to avoid unnecessary competition.

Also, when a system is overloaded, now the time space is stretched more
aggressively (i.e., lat_prio^2) when a task's latency priority is low
(high value).

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.
