摘要： A system comprises a plurality of cache agents, a computing entity coupled to the cache agents, and a programmable mask accessible to the computing entity. The programmable mask is indicative of, for at least one memory address, those cache agents that can receive a snoop request associated with a memory address. Based on the mask, the computing entity transmits snoop requests, associated with the memory address, to only those cache agents identified by the mask as cache agents that can receive a snoop request associated with the memory address.

摘要： A method and system for migrating at least one critical resource during a migration of an operative portion of a computer system are disclosed. In at least some embodiments, the method includes (a) sending first information constituting a substantial copy of a first of the at least one critical resource via at least one intermediary between a source component and a destination component. The method further includes (b) transitioning a status of the destination component from being incapable of receiving requests to being capable of receiving requests, and (c) re-programming an abstraction block to include modified addresses so that at least one incoming request signal is forwarded to the destination component rather than to the source component.

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： 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).
