A computing device having partitions, and a method of communicating between partitions, are disclosed wherein at least one partition comprises: at least one register substantially always accessible to other partitions and capable of defining an address area; at least one address area that may be accessible to other partitions and is capable of being defined by the at least one register; and address areas other than the at least one accessible address area that are not accessible to other partitions. A method of processing interrupts comprising receiving an interrupt, assessing the origin of the interrupt, accepting, rejecting, or further assessing the interrupt, depending on its origin, when further assessing the interrupt, accepting or rejecting the interrupt depending on its contents, and forwarding accepted interrupts but not rejected interrupts to a target processor, and a device carrying out that method are also disclosed.

Methods and apparatus in a partitionable computing system. A state machine monitors the status of a partition or processor system. The security status information can be communicated to a device controller to protect a register within the device controller.
摘要:
An embodiment of a multiprocessor computer system comprises main memory, a remote processor capable of accessing the main memory, a remote cache device operative to store accesses by said remote processor to said main memory, and a filter tag cache device associated with the main memory. The filter cache device is operative to store information relating to remote ownership of data in the main memory including ownership by the remote processor. The filter cache device is operative to selectively invalidate filter tag cache entries when space is required in the filter tag cache device for new cache entries. The remote cache device is responsive to events indicating that a cache entry has low value to the remote processor to send a hint to the filter tag cache device. The filter tag cache device is responsive to a hint in selecting a filter tag cache entry to invalidate.
摘要:
A computer system, related components such as a processor agent, and related method are disclosed. In at least one embodiment, the computer system includes a first core, at least one memory device including a first memory segment, and a first memory controller coupled to the first memory segment. Further, the computer system includes a fabric and at least one processor agent coupled at least indirectly to the first core and the first memory segment, and also coupled to the fabric. A first memory request of the first core in relation to a first memory location within the first memory segment proceeds to the first memory controller by way of the at least one processor agent and the fabric.
