-- -- TMTEST / SPECIFICATION -- -- DESCRIPTION: -- -- This package is the specification for Test 13 of the RTEMS -- Timing Test Suite. -- -- DEPENDENCIES: -- -- -- -- COPYRIGHT (c) 1989-1997. -- On-Line Applications Research Corporation (OAR). -- Copyright assigned to U.S. Government, 1994. -- -- The license and distribution terms for this file may in -- the file LICENSE in this distribution or at -- http://www.OARcorp.com/rtems/license.html. -- -- $Id$ -- with TIMER_DRIVER; with RTEMS; package TMTEST is -- -- Buffer Record similar to that used by RTEMS 3.2.1. Using this -- avoids changes to the test. -- type BUFFER is record FIELD1 : RTEMS.UNSIGNED32; -- TEMPORARY UNTIL VARIABLE LENGTH FIELD2 : RTEMS.UNSIGNED32; FIELD3 : RTEMS.UNSIGNED32; FIELD4 : RTEMS.UNSIGNED32; end record; -- -- The following is the ID of the message queue used for timing operations. -- QUEUE_ID : RTEMS.ID; -- -- The following variable is set to the execution time returned -- by the timer. -- END_TIME : RTEMS.UNSIGNED32; -- -- INIT -- -- DESCRIPTION: -- -- This RTEMS task initializes the application. -- procedure INIT ( ARGUMENT : in RTEMS.TASK_ARGUMENT ); -- -- TEST_INIT -- -- DESCRIPTION: -- -- This subprogram performs test initialization. As each application -- task is created and started, it will preempt this task and -- perform a blocking MESSAGE_QUEUE_RECEIVE. Once all of the -- initialization is completed, the timer is started and the first -- preemptive MESSAGE_QUEUE_URGENT is executed. -- procedure TEST_INIT ( ARGUMENT : in RTEMS.TASK_ARGUMENT ); -- -- HIGH_TASK -- -- DESCRIPTION: -- -- This RTEMS task is the highest priority task in the system. -- It performs a blocking blocking MESSAGE_QUEUE_RECEIVE. It is -- the last test task created and started. Thus it is the last -- task to be enqueued waiting for a message and the last task -- to receive the message. Once it receives the message, it -- stops the timer and reports the execution time for a -- preemptive MESSAGE_QUEUE_URGENT. -- procedure HIGH_TASK ( ARGUMENT : in RTEMS.TASK_ARGUMENT ); -- -- MIDDLE_TASKS -- -- DESCRIPTION: -- -- As each of these RTEMS tasks is created and started, it preempts -- the initialization task and perform a blocking MESSAGE_QUEUE_RECEIVE. -- procedure MIDDLE_TASKS ( ARGUMENT : in RTEMS.TASK_ARGUMENT ); end TMTEST;
