Task Placement in the Linux CFS Scheduler: Scenarios, Code Framework, and Energy‑Aware Scheduling

The article explains how the Linux CFS scheduler places newly created or awakened tasks—during fork, exec, or wake‑up—by using sched domains and flags to invoke select_task_rq_fair, which then chooses among energy‑aware, least‑loaded, or idle‑sibling CPUs based on capacity, energy impact, and affinity.
