摘要： A method, computer program product, and distributed data processing system that allows a single physical I/O adapter, such as a PCI, PCI-X, or PCI-E adapter, to validate that a direct memory access address referenced by an incoming I/O transaction that was initiated through a memory mapped I/O operation are associated with a virtual adapter or virtual resource that is referenced by the incoming memory mapped I/O operation is provided. Specifically, the present invention is directed to a mechanism for sharing conventional PCI (Peripheral Component Interconnect) I/O adapters, PCI-X I/O Adapters, PCI-Express I/O Adapters, and, in general, any I/O adapter that uses a memory mapped I/O interface for communications. A single physical I/O adapter validates that one or more direct memory access addresses referenced by an incoming I/O transaction initiated through a memory mapped I/O operation are associated with a virtual adapter or virtual resource that is referenced by the incoming memory mapped I/O operation.

摘要： A mechanism for handling event notifications or interrupts in a logically partitioned computing system having IO adapters that support adapter virtualization are provided. A virtual adapter associated with a physical IO adapter detects an event, identifies a logical partition associated with the event, and writes an event notification entry in a partition interrupt control block (PICB) of the logical partition memory space. The virtual adapter notifies shared control point logic on the physical IO adapter of the update to the PICB which may then write an entry to a logical partition manager interrupt control block (LPAR manager ICB) identifying the update to the PICB and the operating system associated with the PICB. The LPAR manager may then inform the operating system of the logical partition of the updates to the PICB which may then read the entries in the PICB, process them and inform appropriate application instances of the events.

摘要： The system I/O interface and its data structure are designed to minimize the host CPU utilization in driving an adapter. The interface is also designed to reduce the system interference in processing I/O requests. To eliminate the need of using PIO instructions, the command/status blocks for exchanging messages between the system and the adapter reside in the system memory. The data structure is designed to avoid "share write" entries in order to further minimize the overhead of maintaining each coherency when updating an entry in the cache either concurrently or sequentially by both adapter and system CPU. Further, the data structure of the control and status blocks is resided in the system memory. The system CPU uses STORE instruction to prepare control blocks and LOAD instruction to read from completion status blocks; while the adapter will rely on its DMA engine to move data to/from system memory in accessing control/status blocks.
摘要翻译：系统I / O接口及其数据结构旨在最大限度地减少驱动适配器时的主机CPU利用率。该接口还旨在减少处理I / O请求时的系统干扰。为了不需要使用PIO指令，系统和适配器之间交换消息的命令/状态块驻留在系统内存中。数据结构旨在避免“共享写入”条目，以便在适配器和系统CPU同时或顺序更新缓存中的条目时进一步最小化维护每个一致性的开销。此外，控制和状态块的数据结构驻留在系统存储器中。系统CPU使用STORE指令准备控制块和LOAD指令，从完成状态块读取; 而适配器将依靠其DMA引擎在访问控制/状态块时将数据移入/移出系统内存。

摘要： A mechanism for offloading the management of send queues in a split socket stack environment, including efficient split socket queue flow control and TCP/IP retransmission support. An Upper Layer Protocol (ULP) creates send work queue entries (SWQEs) for writing to the send work queue (SWQ). The Internet Protocol Suite Offload Engine (IPSOE) is notified of a new entry to the SWQ and it subsequently reads this entry that contains pointers to the data that is to be transmitted. After the data is transmitted and acknowledgments are received, the IPSOE creates a completion queue entry (CQE) that is written into the completion queue (CQ). The flow control between the ULP and the IPSOE is credit based. The passing of CQ credits is the only explicit mechanism required to manage flow control of both the SWQ and the CQ between the ULP and the IPSOE.

摘要： The present invention provides a method that enables application instances to pass block mode storage requests directly to a physical I/O adapter without run-time involvement from either the local operating system or hypervisor. In one aspect of the present invention, a mechanism is provided for determining whether a user space operation is a resource management operation of a work processing operation. If the user space operation is a resource management operation, appropriate functions are performed to either query, create, modify or destroy resource allocations in the I/O adapter. If the user space operation is a work processing operation, appropriate functions are performed to create work queue entries and inform the I/O adapter of the work queue entries and to retrieve completion queue entries for work queue entries whose processing has been completed by the I/O adapter.

摘要： A mechanism for offloading the management of send queues in a split socket stack environment, including efficient split socket queue flow control and TCP/IP retransmission support. As consumers initiate send operations, send work queue entries (SWQEs) are created by an Upper Layer Protocol (ULP) and written to the send work queue (SWQ). The Internet Protocol Suite Offload Engine (IPSOE) is notified of a new entry to the SWQ and it subsequently reads this entry that contains pointers to the data that is to be transmitted. After the data is transmitted and acknowledgments are received, the IPSOE creates a completion queue entry (CQE) that is written into the completion queue (CQ). After the CQE is written, the ULP subsequently processes the entry and removes it from the CQE, freeing up a space in both the SWQ and CQ. The number of entries available in the SWQ are monitored by the ULP so that it does not overwrite any valid entries. Likewise, the IPSOE monitors the number of entries available in the CQ, so as not overwrite the CQ. The flow control between the ULP and the IPSOE is credit based. The passing of CQ credits is the only explicit mechanism required to manage flow control of both the SWQ and the CQ between the ULP and the IPSOE.
摘要翻译：一种卸载分组套接字堆栈环境中发送队列管理的机制，包括高效的分裂套接字队列流控制和TCP / IP重传支持。当消费者发起发送操作时，发送工作队列条目（SWQE）由上层协议（ULP）创建并写入发送工作队列（SWQ）。互联网协议套件卸载引擎（IPSOE）被通知一个新条目到SWQ，它随后读取这个条目，其中包含指向要发送的数据的指针。在发送数据并接收到确认之后，IPSOE创建写入完成队列（CQ）的完成队列条目（CQE）。在编写CQE后，ULP随后处理该条目并将其从CQE中删除，从而释放了SWQ和CQ两者的空间。 SWQ中可用的条目数由ULP进行监视，以使其不会覆盖任何有效的条目。同样，IPSOE监视CQ中可用条目的数量，以免覆盖CQ。 ULP和IPSOE之间的流量控制是基于信用的。 CQ信用证的通过是在ULP和IPSOE之间管理SWQ和CQ两者流量控制所需的唯一明确的机制。

摘要： A system and method for establishing multiple connections using a private data field of a communication management protocol is provided. With the present invention, a Service ID identifies a specific consumer and the private data field contains a list of connection attributes for each connection that is to be established. An active side requests a connection and the passive side replies to the connection request. The active side sends the passive side a connection establishment request. This connection establishment request includes a Service ID which identifies a passive side process associated with a service. This connection establishment request also includes communication attributes of one or more connected services and datagram services associated with the Service ID. The passive passes the connection request to a process associated with the service. If the passive side process does not wish to carry out the service, a negative reply message is returned to the active side. If the passive side process does wish to carry out the service, a positive reply is returned to the active side and the reply includes the communication attributes for the connection and unreliable services associated with the Service ID used in the connection establishment request.

摘要： A method, system, and product in a data processing system are disclosed for managing data transmitted from a first end node to a second end node included in the data processing system. A logical connection is established between the first end node and the second end node prior to transmitting data between the end nodes. An instance number is associated with this particular logical connection. The instance number is included in each packet transmitted between the end nodes while this logical connection remains established. The instance number remains constant during this logical connection. The instance number is altered, such as by incrementing it, each time a logical connection between these end nodes is reestablished. Thus, each packet is associated with a particular instance of the logical connection. When a packet is received, the instance number included in the packet may be used to determine whether the packet is a stale packet transmitted during a previous logical connection between these end nodes.
