package TMTEST is
--
-- The following is the name used for all periods created by this test.
--
PERIOD_NAME : RTEMS.NAME;
--
-- The following is used to allow all tasks to create and start
-- their period timers before the timer is started for timing
-- the blocking case of RATE_MONOTONIC_PERIOD.
--
TASK_COUNT : RTEMS.UNSIGNED32;
--
-- 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. It also measures and
-- reports the following directive execution times:
--
-- + RATE_MONOTONIC_CREATE
-- + RATE_MONOTONIC_PERIOD the initial time
-- + RATE_MONOTONIC_PERIOD for a period's status
-- + RATE_MONOTONIC_CANCEL
-- + RATE_MONOTONIC_DELETE of a cancelled period
-- + RATE_MONOTONIC_DELETE of an active period
--
procedure INIT (
ARGUMENT : in RTEMS.TASK_ARGUMENT
);
--
-- TEST_TASK
--
-- DESCRIPTION:
--
-- The first of these RTEMS tasks starts the timer. All of these
-- tasks execute a blocking RATE_MONOTONIC_PERIOD.
--
procedure TASKS (
ARGUMENT : in RTEMS.TASK_ARGUMENT
);
--
-- TEST_TASK
--
-- DESCRIPTION:
--
-- This RTEMS task stops the timer and reports the execution
-- time for a blocking RATE_MONOTONIC_PERIOD.
--
