VIRTUAL-INTERRUPT-MODE INTERFACE AND METHOD FOR VIRTUALIZING AN INTERRUPT MODE

摘要

embodiment of the present invention is older than the new interrupt interrupt generation devices that do not have more than the old interrupt mode to continue to be used in a system that depends on the mode, to a method for virtual interrupt mode in place of the I / O device controller 702, the interrupt-generating device comprising a 706. In one embodiment of the present invention, I / O device controller, operating system, BIOS layer, and the I / O device controller 702 to communicate with other components and the interrupt mode, to provide a virtual interrupt mode, in place of such an interrupt-generating device virtualization, or virtual interrupt-mode interface to provide a PCIe switch 802, 704 or PCIe-based host bridge 804 is changed, or, or a new component is introduced.
