摘要： Techniques are provided for allocating a plurality of resources on a chip to a plurality of partitions in a partitionable computer system. In one embodiment, a resource allocated to a first partition generates a physical address in an address space allocated to the first partition. A partition identification value identifies the first partition. The first partition identification value is stored in the first physical address to produce a partition-identifying address, which may be transmitted to a system fabric. In another embodiment, a transaction is received which includes a source terminus identifier identifying a source device which transmitted the transaction. It is determined, based on the source terminus identifier, whether the source device is allocated to the same partition as any of the plurality of resources. If the source device is so allocated, the transaction is transmitted to a resource that is allocated to the same partition as the source device.

摘要： Systems, methodologies, media, and other embodiments associated with external virtualization are described. One exemplary system embodiment includes an emulation logic located external to an integrated circuit to which it may be operably connected. The example emulation logic may include a virtualization logic that is configured to virtualize a portion of a function performed by the integrated circuit. The portion may be identifiable by an address associated with the portion. The example emulation logic may also include a data store that is operably connected to the virtualization logic and that is configured to store a state data associated with virtualizing the portion of the function.

摘要： Systems, methodologies, media, and other embodiments associated with a system configured with a trap mode register, multiple interrupt vector address registers, and multiple interrupt vector tables are described. One exemplary system embodiment includes a logic for initializing the trap mode register, for initializing interrupt vector address registers, and for initializing interrupt vector tables. When a trap occurs in a computer configured with the exemplary system, the trap mode register may select, based, for example, on the trap type or a trap data, an associated interrupt vector address register to provide an address of an interrupt vector table through which a trap handler can be invoked.

摘要： A system and method for achieving one or more protected regions within a computer system having multiple partitions are disclosed. In at least some embodiments, the system includes an intermediary device for use within the computer system having the multiple partitions. The intermediary device includes a fabric device, and a first firewall device capable of limiting communication of a signal based upon at least one of a source of the signal and an intended destination of the signal, the first firewall device being at least indirectly coupled to the fabric device. The intermediary device further includes a first conversion device that is one of integrated with the first firewall device and distinct from the first firewall device, and that is capable of converting between a processor address and a fabric address for use by the fabric device. In some embodiments, the various devices each include Control and Status Registers (CSRs).
