74 * This module contains all RTEMS Configuration parameters.

76 * The model is to estimate the memory required for each configured item
77 * and sum those estimates.  The estimate can be too high or too low for
78 * a variety of reasons:
79 *
80 * Reasons estimate is too high:
81 *   + FP contexts (not all tasks are FP)
82 *
83 * Reasons estimate is too low:
84 *   + stacks greater than minimum size
85 *   + messages
86 *   + application must account for device driver resources
87 *   + application must account for add-on library resource requirements
88 *
89 * NOTE:  Eventually this may be able to take into account some of
90 *        the above.  This procedure has evolved from just enough to
91 *        support the RTEMS Test Suites into something that can be
92 *        used remarkably reliably by most applications.

632 * @brief Maximum priority configuration.
633 *
634 * This configures the maximum priority value that
635 * a task may have.
636 *
637 * The following applies to the data space requirements
638 * of the Priority Scheduler.
639 *
640 * By reducing the number of priorities in a system,
641 * the amount of RAM required by RTEMS can be significantly
642 * reduced.  RTEMS allocates a Chain_Control structure per
643 * priority and this structure contains 3 pointers.  So
644 * the default is (256 * 12) = 3K on 32-bit architectures.
645 *
646 * This must be one less than a power of 2 between
647 * 4 and 256.  Valid values along with the application
648 * priority levels and memory saved when pointers are
649 * 32-bits in size are:
650 *
651 *   + 3,  2 application priorities, 3024 bytes saved
652 *   + 7, 5 application priorities, 2976 bytes saved
653 *   + 15, 13 application priorities, 2880 bytes saved
654 *   + 31, 29 application priorities, 2688 bytes saved
655 *   + 63, 61 application priorities, 2304 bytes saved
656 *   + 127, 125 application priorities, 1536 bytes saved
657 *   + 255, 253 application priorities, 0 bytes saved
658 *
659 * It is specified in terms of Classic API priority values.
