In some games (e.g., Elden Ring), it was observed that preemption happens much less frequently. The reason is that tasks' runtime per schedule is similar, so it does not meet the existing criteria. To alleviate the problem, the following three tunables are revised: 1) Smaller LAVD_PREEMPT_KICK_MARGIN and LAVD_PREEMPT_TICK_MARGIN help to trigger more preemption. 2) Smaller LAVD_SLICE_MAX_NS works better especially 250 or 300Hz kernels. 3) Longer LAVD_ELIGIBLE_TIME_MAX purturbes time lines less frequently.

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.
