WebSmall kernel modules to test the gpio interrupt work in a RaspberryPi computer. irqflow. The irqflow module waits for a stream of interrupt events arriving at one or more gpio pins with a regular cadence. Each event is checked for coherency with the flow; ... WebSystems often use an interrupt controller to group the device interrupts together before passing on the signal to a single interrupt pin on the CPU. This saves interrupt pins on the CPU and also gives flexibility when designing systems. The interrupt controller has mask and status registers that control the interrupts.
