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/ (cherry picked from commit 016e9d8d08ce66f5e81b42e0a0db398afc17336a) (cherry picked from commit fb7ec285c98d9eeaa69d1efda3e450e6f7207e57) (cherry picked from commit 02e50f7a4b53e56b051889b982fa43118c577493) (cherry picked from commit fc96019babd5658b140ea2f45bfda5fd101434c7)
