choice SCHED_ALGORITHM: Scheduler priority queue algorithm

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

• SCHED_DUMB

Choice options

• SCHED_DUMB

• SCHED_SCALABLE

• SCHED_MULTIQ
