-- Timing Test Suite.

package TMTEST is
--
-- 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
);
--
-- This is the Initialization Tasks Table for this test.
--
