    摘要: A method for switching between a first mode and a second mode of a processor is provided. According to one embodiment of the invention, a computer system includes the processor coupled to a storage device storing a number of instructions. In response to a first interrupt, a first information is stored in the storage device for switching to processing in the first mode starting at a first of the number of instructions. In response to a second interrupt occurring subsequent to the storing of the first information, said processor switches from processing in the first mode to processing in the second mode. Also in response to the second interrupt, a second information is storm in the storage device for returning to processing in the first mode starting at a second of the number of instructions. In response to said processor switching from said first mode to said second mode, said processor switches from processing in the second mode to processing in the first mode starting at the first instruction using the first information if processing starting at the first instruction is required.

    摘要: Apparatus and systems, as well as methods and articles, may operate to detect an input/output access operation associated with a configuration memory address and a first memory address bit size. The configuration memory address and associated configuration data may be combined into a packet having a second memory address bit size (e.g., 64 bits) greater than the first memory address bit size (e.g., 32 bits). The packet may be used to establish compatibility for legacy operating systems that attempt to communicate with peripheral component interconnect (PCI) interface-based peripherals, and similar platform devices, that have been integrated into the same package as the processor.
