Small improvement to make the scheduler a bit more responsive, without introducing too much complexity or too much CPU overhead. This can be achieved by replacing a sleep of 1ms with a sched_yield() every time that the scheduler has finished to dispatch all the queued tasks. This also makes the code a bit smaller and easier to read. Signed-off-by: Andrea Righi <andrea.righi@canonical.com> |

scx_rlfifo
This is a single user-defined scheduler used within sched_ext, which is a Linux kernel feature which enables implementing kernel thread schedulers in BPF and dynamically loading them. Read more about sched_ext.
Overview
scx_rlfifo is a simple FIFO scheduler runs in user-space, based on the scx_rustland_core framework.
Typical Use Case
This scheduler is provided as a simple template that can be used as a baseline to test more complex scheduling policies.
Production Ready?
Definitely not. Using this scheduler in a production environment is not recommended, unless there are specific requirements that necessitate a basic FIFO scheduling approach. Even then, it's still recommended to use the kernel's SCHED_FIFO real-time class.
