Hi. I wonder if a handler of interrupt handling and the other handler of real-time periodic task coexist in a module I tested above case like the following. int init_module( ){ request_RTirq(...) ; rt_task_init(...) ; rt_task_make_periodic(...) ; return 1 ; } Of course, I have the handlers for both respectively. However, my system worked improperly. Only the trial handler which displays some characters on the screen worked continually and forever!!, on the other hand, the interrupt handler seemed not to work( I couldn't verify it ). Indeed, all system but the periodic task handler stoped. Is the coexistence impossible?
