摘要： In a computer system, an I/O adapter comprises at least one I/O request mailbox for receiving I/O requests and data from a CPU. The mailbox is connected to at least one I/O request queue storage for storing a plurality of I/O requests and related data or main memory addresses received by the mailbox. A credit register is provided for storing the filling state of the queue storage. A connection network is designed and operated to transfer the contents of the credit register to the CPU for checking the filling state of the queue storage, to transfer an I/O request and related data to a queue of a selected request mailbox, and to activate a doorbell apparatus for signalling to the I/O adapter to process the I/O request including an access to the main memory by the I/O adapter if required.

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.

摘要： A system and method for multicore 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.
摘要翻译：提供了一种用于数据处理设备之间的通信的多核处理的系统和方法。利用说明性实施例的机制，提供了一组通过在多个处理核上分发发送和接收侧处理来维持媒体速度的技术。此外，这些技术还可以设计出多线程网络接口控制器（NIC）硬件，可有效地隐藏通过输入/输出（I / O）总线传输数据分组的直接存储器访问（DMA）操作的延迟。多个处理核心可以使用通信协议栈和设备驱动程序的单独实例同时运行，以处理用于传输的数据分组，其中单独的硬件实现了处理这些数据分组以进行传输的网络适配器中的发送队列管理器。可以使用网络适配器中的多个硬件接收分组处理器以及流分类引擎将接收到的数据分组路由到适当的接收队列和处理核心进行处理。
