Linux Process Scheduling

1. Scheduler overview

   Index of kernel scheduler documents covering fair, real-time and deadline classes.

2. CFS design

   Completely Fair Scheduler virtual runtime, red-black tree runqueue, nice weights and scheduling classes.

3. EEVDF scheduler

   Earliest Eligible Virtual Deadline First with lag, eligibility, virtual deadlines and slice length.

4. Scheduling domains

   Sched domains and groups used for multi-core and NUMA load balancing.

5. Deadline scheduler

   SCHED_DEADLINE runtime, deadline and period parameters, constant bandwidth server and admission control.

6. Real-time group scheduling

   SCHED_FIFO and SCHED_RR bandwidth limits for control groups.

7. CFS bandwidth control

   cpu.cfs_quota_us and period throttling of CPU time per cgroup.

8. Energy aware scheduling

   Energy model driven task placement on heterogeneous CPUs.

9. Capacity-aware scheduling

   CPU capacity, utilization and misfit tasks on asymmetric systems.

10. Scheduler statistics

    Per-CPU and per-domain schedstat counters in /proc/schedstat.

11. sched_ext extensible scheduler

    Writing BPF-defined schedulers with dispatch queues and ops callbacks.
