60 * This module contains all RTEMS Configuration parameters.
61 *
62 * The model is to estimate the memory required for each configured item
63 * and sum those estimates.  The estimate can be too high or too low for
64 * a variety of reasons:
65 *
66 * Reasons estimate is too high:
67 *   + FP contexts (not all tasks are FP)
68 *
69 * Reasons estimate is too low:
70 *   + stacks greater than minimum size
71 *   + messages
72 *   + application must account for device driver resources
73 *   + application must account for add-on library resource requirements
74 *
75 * NOTE:  Eventually this may be able to take into account some of
76 *        the above.  This procedure has evolved from just enough to
77 *        support the RTEMS Test Suites into something that can be
78 *        used remarkably reliably by most applications.

753 *
754 * The following applies to the data space requirements
755 * of the Priority Scheduler.
756 *
757 * By reducing the number of priorities in a system,
758 * the amount of RAM required by RTEMS can be significantly
759 * reduced.  RTEMS allocates a Chain_Control structure per
760 * priority and this structure contains 3 pointers.  So
761 * the default is (256 * 12) = 3K on 32-bit architectures.
762 *
763 * This must be one less than a power of 2 between
764 * 4 and 256.  Valid values along with the application
765 * priority levels and memory saved when pointers are
766 * 32-bits in size are:
767 *
768 *   + 3,  2 application priorities, 3024 bytes saved
769 *   + 7, 5 application priorities, 2976 bytes saved
770 *   + 15, 13 application priorities, 2880 bytes saved
771 *   + 31, 29 application priorities, 2688 bytes saved
772 *   + 63, 61 application priorities, 2304 bytes saved
773 *   + 127, 125 application priorities, 1536 bytes saved
774 *   + 255, 253 application priorities, 0 bytes saved
775 *
776 * It is specified in terms of Classic API priority values.
