CONFIG_SCHED_DUMB
¶
Simple linked-list ready queue
Type: bool
Help¶
When selected, the scheduler ready queue will be implemented as a simple unordered list, with very fast constant time performance for single threads and very low code size. Choose this on systems with constrained code size that will never see more than a small number (3, maybe) of runnable threads in the queue at any given time. On most platforms (that are not otherwise using the red/black tree) this results in a savings of ~2k of code size.
Direct dependencies¶
