ABSTRACT:
A computer implemented method, an apparatus, and a computer usable program product for tracking device driver requests in a data processing system is provided. A controller receives a request from a device driver. The controller associates a timestamp and at least one pointer to the request, wherein the timestamp indicates a time the request is received by an operating system. The controller then links the request from the device driver in a queue in the operating system, wherein the pointer identifies the location of the request in the queue.
