摘要： A system and method is disclosed for performing error recovery in a data processing system that supports multiple processing partitions. One or more processors and I/O modules, as well as a portion of the address space of a main memory, is allocated to each partition. In this type of configuration, requests generated by units of multiple partitions are processed by the same queue and state logic of the main memory. When a failure occurs within one processing partition, one or more units are identified as being directly affected by the fault. All requests and responses from, and to, the affected units, as well as any logical residue of these requests and responses are removed from the shared memory queue and state logic in a manner that allows the other partition to continue issuing requests and responses to the memory in a normal manner that does not involve recovery operations.

摘要： A system and method for managing memory data within a data processing system is disclosed. A main memory is provided to store data signals. When the main memory receives a request to read data signals, the main memory determines whether an updated copy of the requested data signals may be stored within some other storage device within the system. If so, the main memory issues a snoop request to this other storage device to cause any updated copy of the requested data to be returned to the main memory. In addition, the main memory reads the requested data signals from its data store. This data will be used to satisfy the read request if an updated copy of the data signals is not returned to the main memory in response to the snoop request. Otherwise, the updated copy is provided to fulfill the request.
