摘要： Mechanisms for processing of communications between data processing devices are provided. With the mechanisms of the illustrative embodiments, a set of techniques that enables sustaining media speed by distributing transmit and receive-side processing over multiple processing cores is provided. In addition, these techniques also enable designing multi-threaded network interface controller (NIC) hardware that efficiently hides the latency of direct memory access (DMA) operations associated with data packet transfers over an input/output (I/O) bus. Multiple processing cores may operate concurrently using separate instances of a communication protocol stack and device drivers to process data packets for transmission with separate hardware implemented send queue managers in a network adapter processing these data packets for transmission. Multiple hardware receive packet processors in the network adapter may be used, along with a flow classification engine, to route received data packets to appropriate receive queues and processing cores for processing.

The sending hardware system includes a first memory system and a receiving hardware system which includes a second memory system with a second data buffer and a second memory region. The sending hardware system and the receiving hardware system are coupled via a non-transparent bridge unit. The method includes allocating empty memory, writing information about the empty memory, copying payload data directly from the sending hardware system to the empty memory locations, and writing information about the copied payload data to the second data buffer of the second memory system inside the receiving hardware system. A computer program product for carrying out the method is also provided.

摘要： A data processing system includes a main storage, an input/output memory management unit (IOMMU) coupled to the main storage, a peripheral component interconnect (PCI) device coupled to the IOMMU, and a mapper. The system is configured to allocate an amount of physical memory in the main storage and the IOMMU is configured to provide access to the main storage and to map a PCI address from the PCI device to a physical memory address within the main storage. The mapper is configured to perform a mapping between the allocated amount of physical memory of the main storage and a contiguous PCI address space. The IOMMU is further configured to translate PCI addresses of the contiguous PCI address space to the physical memory address within the main storage.
