Files (use right click "save as..." or use wget to get the files):
Be carefull before running an rtai aplication: check that there is no infinite
loop, check that you free all ressources you allocate.
Trace tools do not scale very good. To correctly visualyze your system, use
"printk" primitive and dmesg to see the kernel log.
Remember to make screen copy for your report.
Primitive rt_preempt_always()(see doc) permits to be sure that a task will always be preempted instantaneously by an higher priority task.
To avoid task execution on several processors, you can use
int rt_task_int_cpuid(RT_TASK *task, void(*rt_thread)(int), int data, int stack_size, int priority, int uses_fpu, void(*signal)(void), unsigned int cpuid) instead of
rt_task_init with value 0 for the last argument (cpuid).
