Linux Real-Time Thread CPU Selection Process

The article details Linux’s real‑time thread CPU‑selection process, explaining how priorities (0‑99 for rt, 100‑139 for CFS) set the sched_class, how functions like select_task_rq_rt, find_lowest_rq, cpupri_find_fitness and __cpupri_find build a candidate CPU mask, and how the final CPU is chosen by previous affinity, domain order, wake‑up CPU or random selection, while warning that excessive rt tasks can increase power use and cause scheduling delays.
