25.3.3: Reporting Task Stack Usage

The application may dynamically report the stack usage for every task in the system by calling the rtems.stack_checker_report_usage routine. This routine prints a table with the peak usage and stack size of every task in the system. The following is an example of the report generated:

    ID      NAME       LOW        HIGH     AVAILABLE      USED
0x04010001  IDLE  0x003e8a60  0x003e9667       2952        200
0x08010002  TA1   0x003e5750  0x003e7b57       9096       1168
0x08010003  TA2   0x003e31c8  0x003e55cf       9096       1168
0x08010004  TA3   0x003e0c40  0x003e3047       9096       1104
0xffffffff  INTR  0x003ecfc0  0x003effbf      12160        128

Notice the last time. The task id is 0xffffffff and its name is "INTR". This is not actually a task, it is the interrupt stack.
