    摘要： A data processing system includes a plurality of communication links and a plurality of processing units including a local master processing unit. The local master processing unit includes interconnect logic that couples the processing unit to one or more of the plurality of communication links and an originating master coupled to the interconnect logic. The originating master originates an operation by issuing a write-type request on at least one of the one or more communication links, receives from a snooper in the data processing system a destination tag identifying a route to the snooper, and, responsive to receipt of the combined response and the destination tag, initiates a data transfer including a data payload and a data tag identifying the route provided within the destination tag.

    摘要： A data processing system includes a plurality of processing units each having a respective point-to-point communication link with each of multiple others of the plurality of processing units but fewer than all of the plurality of processing units. Each of the plurality of processing units includes interconnect logic, coupled to each point-to-point communication link of that processing unit, that broadcasts requests received from one of the multiple others of the plurality of processing units to one or more of the plurality of processing units. The interconnect logic includes a partial response data structure including a plurality of entries each associating a partial response field with a plurality of flags respectively associated with each processing unit containing a snooper from which that processing unit will receive a partial response. The interconnect logic accumulates partial responses of processing units by reference to the partial response field to obtain an accumulated partial response, and when the plurality of flags indicate that all processing units from which partial responses are expected have returned a partial response, outputs the accumulated partial response.

    摘要： In a data processing system, a plurality of agents communicate operations therebetween. Each operation includes a request and a combined response representing a system-wide response to the request. Within data storage in the data processing system, a data structure indicates a duration of a protection window extension for each of the plurality of agents. Each protection window extension is a period following receipt of a combined response during which an associated one of the plurality of agents protects transfer of coherency ownership of a data granule between agents. Each of the plurality of agents is configured with a duration of a protection window extension by reference to the data structure, and at least two of the agents have protection window extensions of differing durations. The plurality of agents thereafter employ the configured protection window extensions.

    摘要： A data processing system includes at least a first processing node having an input/output (I/O) controller and a second processing including a memory controller for a memory. The memory controller receives, in order, pipelined first and second DMA write operations from the I/O controller, where the first and second DMA write operations target first and second addresses, respectively. In response to the second DMA write operation, the memory controller establishes a state of a domain indicator associated with the second address to indicate an operation scope including the first processing node. In response to the memory controller receiving a data access request specifying the second address and having a scope excluding the first processing node, the memory controller forces the data access request to be reissued with a scope including the first processing node based upon the state of the domain indicator associated with the second address.

    摘要： A cache coherent data processing system includes at least first and second coherency domains coupled for communication. The first and second coherency domains each include a respective one of first and second cache memories. A master in the first coherency domain selects a scope of an initial broadcast of an operation from among a first scope including only the first coherency domain and a second scope including both the first and second coherency domains based, at least in part, upon a type of the operation. The master then performs an initial broadcast of the operation within the cache coherent data processing system utilizing the selected scope.

    摘要： A data processing system includes a plurality of processing units coupled by a plurality of communication links for point-to-point communication such that at least some of the communication between multiple different ones of the processing units is transmitted via intermediate processing units among the plurality of processing units. The communication includes operations having a request and a combined response representing a system response to the request. At least each intermediate processing unit includes one or more masters that initiate first operations, a snooper that receives at least second operations initiated by at least one other of the plurality of processing units, a physical queue that stores master tags of first operations initiated by the one or more masters within that processing unit, and a ticketing mechanism that assigns to second operations observed at the intermediate processing unit a ticket number indicating an order of observation with respect to other second operations observed by the intermediate processing unit. The ticketing mechanism provides the ticket number assigned to an operation to the snooper for processing with a combined response of the operation.
