Abstract:
An apparatus, method, system, and computer-readable medium are disclosed. In one embodiment the apparatus is a processor. The processor includes thread remapping logic that is capable of tracking hardware thread interrupt equivalence information for a first hardware thread and a second hardware thread. The processor also includes logic to receive an interrupt issued from a device, wherein the interrupt has an affinity tied to the first hardware thread. The processor also includes logic to redirect the interrupt to the second hardware thread when the hardware thread interrupt equivalence information validates the second hardware thread is capable of handling the interrupt.
