87 * The model is to estimate the memory required for each configured item
88 * and sum those estimates.  The estimate can be too high or too low for
89 * a variety of reasons:
90 *
91 * Reasons estimate is too high:
92 *   + FP contexts (not all tasks are FP)
93 *
94 * Reasons estimate is too low:
95 *   + stacks greater than minimum size
96 *   + messages
97 *   + application must account for device driver resources
98 *   + application must account for add-on library resource requirements
99 *
100 * NOTE:  Eventually this may be able to take into account some of
101 *        the above.  This procedure has evolved from just enough to
102 *        support the RTEMS Test Suites into something that can be
103 *        used remarkably reliably by most applications.

643 * @brief Maximum priority configuration.
644 *
645 * This configures the maximum priority value that
646 * a task may have.
647 *
648 * The following applies to the data space requirements
649 * of the Priority Scheduler.
650 *
651 * By reducing the number of priorities in a system,
652 * the amount of RAM required by RTEMS can be significantly
653 * reduced.  RTEMS allocates a Chain_Control structure per
654 * priority and this structure contains 3 pointers.  So
655 * the default is (256 * 12) = 3K on 32-bit architectures.
656 *
657 * This must be one less than a power of 2 between
658 * 4 and 256.  Valid values along with the application
659 * priority levels and memory saved when pointers are
660 * 32-bits in size are:
661 *
662 *   + 3,  2 application priorities, 3024 bytes saved
663 *   + 7, 5 application priorities, 2976 bytes saved
664 *   + 15, 13 application priorities, 2880 bytes saved
665 *   + 31, 29 application priorities, 2688 bytes saved
666 *   + 63, 61 application priorities, 2304 bytes saved
667 *   + 127, 125 application priorities, 1536 bytes saved
668 *   + 255, 253 application priorities, 0 bytes saved
669 *
670 * It is specified in terms of Classic API priority values.
