.. title:: SCHED_DEADLINE

.. option:: 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``.
