Abstract
An apparatus includes an input/output (I/O) address verification unit that determines whether an I/O address received from a processor is protected. An interrupt generator is coupled to the I/O address verification unit. The interrupt generator generates an interrupt if the I/O address is protected. An interrupt recorder is coupled to the address verification unit. The interrupt recorder records a cause of the interrupt.
