The kernel's sched_setattr interface allows for more control over a processes scheduling attributes as the previously used sched_setscheduler interface. Using sched_setattr is also the prerequisite for support of utilization clamping (UCLAMP [1], see #26705) and allows to set sched_runtime. The latter, sched_runtime, will probably become a relevant scheduling parameter of the EEVDF scheduler [2, 3], and therefore will not only apply to processes scheduled via SCHED_DEADLINE, but also for processes scheduled via SCHED_OTHER/SCHED_BATCH (i.e., most processes). 1: https://docs.kernel.org/next/scheduler/sched-util-clamp.html 2: https://lwn.net/Articles/969062/ 3: https://lwn.net/ml/linux-kernel/20240405110010.934104715@infradead.org/
