Abstract: A data processing apparatus is provided, that includes communication configured for receiving, from an origin Peripheral Component Interconnect Express (PCIe) device, a translated PCIe packet comprising a destination field that comprises a physical address of a destination PCIe device.

Abstract: The present disclosure provides a system and methods for transferring data across an interconnect. One method includes, at a request node, receiving, from a source high speed serial controller, a write request from a source, dividing the write request into sequences of smaller write requests each having a last identifier, and sending, to a home node, the sequences of smaller write requests; and, at the home node, sending, to a destination high speed serial controller, the sequences of smaller write requests for assembly into intermediate write requests that are transmitted to a destination. Each sequence of smaller write requests is assembled into an intermediate write request based on the last identifier.

Abstract: In one embodiment, a processor includes at least one core to execute instructions, one or more thermal sensors associated with the at least one core, and a power controller coupled to the at least one core. The power controller has a control logic to receive temperature information regarding the processor and dynamically determine a maximum allowable average power limit based at least in part on the temperature information. The control logic may further maintain a static maximum base operating frequency of the processor regardless of a value of the temperature information. Other embodiments are described and claimed.

Abstract: Peripheral components, data processing systems and methods of operating such peripheral components and data processing systems are disclosed. The systems comprise an interconnect comprising a system cache, a peripheral component coupled to the interconnect, and a memory coupled to the interconnect. The peripheral component has a memory access request queue for queuing memory access requests in a receipt order. Memory access requests are issued to the interconnect in the receipt order. A memory read request is not issued to the interconnect until a completion response for all older memory write requests has been received from the interconnect. The peripheral component is responsive to receipt of a memory read request to issue a memory read prefetch request comprising a physical address to the interconnect and the interconnect is responsive to the memory read prefetch request to cause data associated with the physical address in the memory to be cached in the system cache.

The power management logic is to receive temperature data from a plurality of dies within a package that includes the processor, and determine a smallest temperature control margin of a plurality of temperature control margins.

Abstract: An apparatus and method are provided for processing flush requests within a packet network. The apparatus comprises a requester device within the packet network arranged to receive a flush request generated by a remote agent requesting that one or more data items be flushed to a point of persistence. The requester device translates the flush request into a packet-based flush command conforming to a packet protocol of the packet network. A completer device within the packet network that is coupled to a persistence domain incorporating the point of persistence is arranged to detect receipt of the packet-based flush command, and then trigger a flush operation within the persistence domain to flush the one or more data items to the point of persistence. This provides a fast, hardware-based, mechanism for performing a flush operation within a persistence domain without needing to trigger software in the persistence domain to handle the flush to the point of persistence.
