+@item Simple Priority Scheduler - This is an alternative scheduler
+in RTEMS. It is designed to provide the same task scheduling behaviour
+as the Deterministic Priority Scheduler while being simpler in implementation
+and uses less memory for data management. It maintains a single sorted list
+of all ready threads. Thus blocking or unblocking a thread is not a
+constant time operation with this scheduler. This scheduler is appropriate
+for use in small systems where RAM is limited. This scheduler may be explicitly
+selected by defining @code{CONFIGURE_SCHEDULER_SIMPLE}.

The pluggable scheduler interface was added after the 4.10 release series
