ABSTRACT:
A method for storing into a non-EX cache line in a multiprocessor system. Upon a store into a non-EX line the instruction execution and the processing of subsequent instructions will continue. The results of the current instruction, however, and any subsequent instruction whose decode and execution depends upon the result of the current instruction or that requires operand fetches, will not be released until the processing of the current instruction is resolved. The request to store into the non-EX line is simultaneously sent to the SCE to obtain the EX state for the line. The SCE serializes storage requests. When a request for EX state is processed, certain XI actions (e.g. XI-invalidates) may be invoked. Any instruction using fetched data XI-invalidated before the resolution of a preceding store at the same CP is considered likely to be invalid, and redone.
