*Scheduler priority queue algorithm*

Type: ``bool``

Help
====

The kernel can be built with with several choices for the
ready queue implementation, offering different choices between
code size, constant factor runtime overhead and performance
scaling when many threads are added.

Default
=======

- \ :option:`SCHED_DUMB <CONFIG_SCHED_DUMB>`

Choice options
==============

- \ :option:`SCHED_DUMB <CONFIG_SCHED_DUMB>`
- \ :option:`SCHED_SCALABLE <CONFIG_SCHED_SCALABLE>`
- \ :option:`SCHED_MULTIQ <CONFIG_SCHED_MULTIQ>`
