interrupt handler

HI, ALL! now i use this mode for interrupt in rtems status = rtems_interrupt_handler_install( STM32F4_IRQ_USART2, "SP2", RTEMS_INTERRUPT_UNIQUE, (rtems_interrupt_handler) USART2_handler, NULL ); for usart i must to make function O0 to make it work well

ere is additional question. I think that CPU time percentage using "cpuuse" is CPU time consuming value except interrupt handler consuming time. Is it correct ? No, the interrupt processing time counts as execution time of the executing thread. Best Regards, Thomas 2018-01-12

le device interrupt handler. Is there any method for checking CPU load about multiple device interrupt handlers ? The is limited support for this. You can try to use enable the profiling option: cpukit/sapi/include/rtems/profiling.h For interrupt profiling a BSP support is necessary. I think

Dear Sir, As I checked until now, thread(task, pthread) cpu load analysis method using "cpuuse" is perfect ! At this time, I am doing multiple device interrupt hander stress testing. but, there is not CPU load anaysis method about multiple device interrupt handler. Is there any
