And a method for the synthesis system interrupt source extensions and interrupt controller

摘要

Synthetic interrupt source interrupt expansion control device (AIC), to provide richer interrupt information (or "synthetic interrupt," "SI") the various embodiments of the present invention relates to the (SIS). SIS AIC and provides an efficient means to transmit and receive interrupt interrupt is transmitted and received by the virtual machine in particular. In particular, regarding interrupt controller that was extended to receive additional information related to the input interrupt, and distributes some of these embodiments. In certain embodiments of such a memory map of the extended interrupt controller includes a data structure that is charged with additional information as part of the interrupt delivery. Some of the embodiments described in the specification, are disclosed in the context of a virtual machine system, the invention disclosed in the specification (no virtualization layer) can be similarly applied to a conventional computer system I can be.
