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_SEND 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_SEND. -- 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. -- INITIALIZATION_TASKS : aliased RTEMS.INITIALIZATION_TASKS_TABLE( 1 .. 1 ) := (1=> ( RTEMS.BUILD_NAME( 'U', 'I', '1', ' ' ), -- task name 2048, -- stack size 1, -- priority RTEMS.DEFAULT_ATTRIBUTES, -- attributes TMTEST.INIT'ACCESS, -- entry point RTEMS.NO_PREEMPT, -- initial mode 0 -- argument list ) ); -- -- This is the Configuration Table for this test. -- CONFIGURATION : aliased RTEMS.CONFIGURATION_TABLE := ( RTEMS.NULL_ADDRESS, -- will be replaced by BSP 256 * 1024, -- executive RAM size 111, -- maximum # tasks 0, -- maximum # timers 0, -- maximum # semaphores 1, -- maximum # message queues 100, -- maximum # messages 0, -- maximum # partitions 0, -- maximum # regions 0, -- maximum # dp memory areas 0, -- maximum # periods 0, -- maximum # user extensions RTEMS.MILLISECONDS_TO_MICROSECONDS(10), -- # us in a tick 0 -- # ticks in a timeslice ); end TMTEST;
