Abstract
Managing hardware function requests incurring variable response latencies is provided. A request for a hardware function is received from a requesting program. The requested hardware function is expected to incur a variable response latency and is implemented as a main hardware function and a retry hardware function. The main hardware function is executed. It is determined whether a fixed response latency of the main hardware function has been exceeded. A response is returned with a retry flag to the requesting program. The retry flag directs the requesting program to issue a request for the retry hardware function after an interval of time. A unique identifier corresponding to the main hardware function is provided to the requesting program.
