Abstract
To emulate an interrupt architecture in a data processing system, interrupt emulation code receives from an operating system a first call requesting access to a first resource in a first interrupt architecture. In response to receipt by the interrupt emulation code of the first call, the interrupt emulation code maps the first resource to a second resource in interrupt hardware of the data processing system. The mapping operation includes determining an identifier of the second resource in a different second interrupt architecture. The interrupt emulation code then initiates access to the second resource implemented by the interrupt hardware.
