CONFIG_SCHED_DEADLINE

Enable earliest-deadline-first scheduling

Type: bool

Help

This enables a simple “earliest deadline first” scheduling mode where threads can set “deadline” deltas measured in k_cycle_get_32() units. Priority decisions within (!!) a single priority will choose the next expiring deadline and not simply the least recently added thread.

Defaults

No defaults. Implicitly defaults to n.
