ABSTRACT:
Provided are a method, system, and program implemented by a device driver executing in a computer for handling interrupts from an associated device, wherein the device driver is capable of interfacing with the associated device. The device driver receives a call requesting whether an interrupt received from a device is from the associated device and reads interrupt status information in memory within the computer to determine whether the associated device transmitted the interrupt, wherein the device writes the interrupt status information to the memory. If the associated device transmitted the interrupt, then the device driver requests resources from the operating system to handle the interrupt.
