This scheduler may be explicitly selected by defining @code{CONFIGURE_SCHEDULER_PRIORITY}. +@findex CONFIGURE_SCHEDULER_SIMPLE +@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}. + @end itemize The pluggable scheduler interface was added after the 4.10 release series |
