Hi, over the last week I implemented a handler for the kqueue()/kevent() syscalls and added a counter, that counts the occurred interrupts, to the driver [1]. Furthermore I wrote user space utilities [2] in order to test the kqueue()/kevent() syscalls and to retrieve respectively reset the counter value. I also wrote an utility that outputs a random bit sequence on a specific pin. During this week I am going to write the second part of the long-term test: An utility that detects the interrupts delivered by the gpiointr driver in user space and evaluates them by replaying the same PRNG as the source. I also start to implement distinction of the single configured pins within a single gpiointr device.
