Zusammenfassung:A method of operating a cache-coherent computing system includes storing first state information corresponding to a first reservation for a first exclusive access to a first memory address requested by a first thread executing on a first processor of a first plurality of processors. The method includes transmitting an output atomic response transaction indicating a status of the first reservation to a coherency interconnection in response to issuance of the first exclusive access to the coherency interconnection. The output atomic response transaction is based on first state information.
