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. |

540 | * |

541 | * This configures the maximum priority value that |

542 | * a task may have. |
---|
543 | * |
---|
544 | * The following applies to the data space requirements |
---|
545 | * of the Priority Scheduler. |
---|
546 | * |
---|
547 | * By reducing the number of priorities in a system, |
---|
548 | * the amount of RAM required by RTEMS can be significantly |
---|
549 | * reduced. RTEMS allocates a Chain_Control structure per |
---|
550 | * priority and this structure contains 3 pointers. So |
---|
551 | * the default is (256 * 12) = 3K on 32-bit architectures. |
---|
552 | * |
---|
553 | * This must be one less than a power of 2 between |
---|
554 | * 4 and 256. Valid values along with the application |
---|
555 | * priority levels and memory saved when pointers are |
---|
556 | * 32-bits in size are: |
---|
557 | * |
---|
558 | * + 3, 2 application priorities, 3024 bytes saved |
---|
559 | * + 7, 5 application priorities, 2976 bytes saved |
---|
560 | * + 15, 13 application priorities, 2880 bytes saved |
---|
561 | * + 31, 29 application priorities, 2688 bytes saved |
---|
562 | * + 63, 61 application priorities, 2304 bytes saved |
---|
563 | * + 127, 125 application priorities, 1536 bytes saved |
---|
564 | * + 255, 253 application priorities, 0 bytes saved |
---|
565 | * |
---|
