The support is very basic - Each component that needs to handle IRQs inherits from InterruptHandler class. When the InterruptHandler constructor is called it registers itself in a SharedInterruptHandler. When an IRQ is fired, the SharedInterruptHandler is invoked, then it iterates through a list of the registered InterruptHandlers. Also, InterruptEnabler class was created to provide a way to enable IRQ handling temporarily, similar to InterruptDisabler (in CPU.h, which does the opposite). In addition to that a PCI::Device class has been added, that inherits from InterruptHandler.
