Abstract (en)
[origin: GB2450516A] A method of servicing interrupts in a computing device having multiple interrupt controllers for receiving interrupt events. An application programming interface (API) includes a first function that is operable to interact with interrupts on two or more of the interrupt controllers. When the first function is invoked for interacting with an interrupt event on a specific one of the interrupt controllers, the first function invokes a second function where the second function can only interact with interrupt events on that specific one of the interrupt controllers. The interrupt controllers may be arranged in a tree, and the second function can invoke a third function on a further interrupt controller. The API may include a fourth function that simulates interaction with a dummy interrupt, such that when the first function is invoked for interacting with a dummy event, it invokes the fourth function.
