摘要： A plurality of address spaces are assigned to an adapter. To select a particular address space for the adapter, a requestor identifier and address space identifier provided in a request by the adapter are used. Each address space may have a different address translation mechanism associated therewith.
摘要翻译：多个地址空间被分配给适配器。为了选择适配器的特定地址空间，使用在适配器的请求中提供的请求者标识符和地址空间标识符。每个地址空间可以具有与其相关联的不同的地址转换机制。

摘要： A request to perform an operation, such as a remote direct memory access (RDMA) write operation or a send operation that writes to memory, is sent from a sending input/output (I/O) adapter (e.g., an RDMA-capable adapter) to a receiving I/O adapter. The receiving I/O adapter receives the request and initiates performance of the operation, but delays sending an acknowledgment for the operation. The acknowledgment is delayed until the operation is complete (i.e., until the memory is updated and the data is visible to the remote processor), as determined by a read operation initiated and performed by the receiving I/O adapter transparent to the sending I/O adapter.
摘要翻译：从发送输入/输出（I / O）适配器（例如，支持RDMA的适配器）发送执行诸如远程直接存储器访问（RDMA）写入操作或写入存储器的发送操作之类的操作的请求）到接收I / O适配器。接收I / O适配器接收请求并发起操作的性能，但延迟发送操作的确认。确认被延迟，直到操作完成（即，直到存储器被更新并且数据对于远程处理器可见），由接收I / O适配器发起和执行的读操作确定，该读操作对发送I / O适配器。

摘要： An address controller includes a bit selector that receives a first portion of a requester id and selects a bit from a vector that identifies whether a requesting function is an SR-IOV device or a standard PCIe device. The controller also includes a selector coupled to the bit selector that forms an output comprised of either a second portion of the RID or a first portion of the address portion based on an input received from the selector and an address control unit that receives the first portion of the RID and the output and determines the LPAR that owns the requesting function based thereon, the address control unit providing the corrected memory request to the memory.
摘要翻译：地址控制器包括位选择器，其接收请求者id的第一部分，并从标识请求功能是SR-IOV设备还是标准PCIe设备的向量中选择一个位。控制器还包括耦合到比特选择器的选择器，其基于从选择器接收的输入形成由RID的第二部分或地址部分的第一部分组成的输出，以及接收第一部分的地址控制单元的RID和输出，并且基于此来确定拥有请求功能的LPAR，地址控制单元向存储器提供校正的存储器请求。

摘要： One or more message signaled interruption requests from one or more input/output (I/O) adapters are converted to I/O adapter event notifications. Each I/O adapter event notification includes the setting of one or more specific indicators in system memory and an interruption request, the first of which results in a pending I/O adapter interruption request. While a request for an I/O adapter interruption is pending, subsequent message signaled interruption requests are converted to I/O adapter event notifications, but do not result in additional requests for I/O adapter interruptions.
摘要翻译：一个或多个来自一个或多个输入/输出（I / O）适配器的信号中断请求被转换为I / O适配器事件通知。每个I / O适配器事件通知包括系统内存中的一个或多个特定指示符的设置和中断请求，其中第一个会导致挂起的I / O适配器中断请求。当I / O适配器中断的请求处于待处理状态时，后续的消息信号中断请求将转换为I / O适配器事件通知，但不会导致对I / O适配器中断的其他请求。

摘要： Communication over a computer network with a node having a first port with a point-to-point link connection to a second node having a second port. The first port transmits to the second port a reliable link layer (RLL) packet over the link. The RLL packet comprises a first RLL header and a first data packet, the first RLL header preceding the first data packet, the first RLL header comprising an RLL start-of-frame (SOF) character and an RLL packet sequence number (PSN). If the first port receives an RLL acknowledgment control packet from the link, it acknowledges receipt of the first data packet, and the first port does not retain the first data packet in the buffer. If the first port does not receive the RLL acknowledgment packet from the link, acknowledging receipt of the first data packet, the first port re-transmits from the buffer the first data packet.

摘要： Send queues provided in an InfiniBand hardware adapter receive a single transmission from a connected computer system which includes work request information, address vector, and message data. This information is sufficient for the adapter to generate packet header information and to send the requested message, thereby providing a low latency sending mechanism. The system stores completion information in tables each dedicated to one of the send queues.
摘要翻译： InfiniBand硬件适配器中提供的发送队列从连接的计算机系统接收单个传输，其中包括工作请求信息，地址向量和消息数据。该信息足以使适配器产生分组报头信息并发送所请求的消息，从而提供低延迟发送机制。系统将完成信息存储在专用于发送队列之一的表中。

摘要： An instruction is provided to establish various operational parameters for an adapter. These parameters include adapter interruption parameters, input/output address translation parameters, resetting error indications, setting measurement parameters, and setting an interception control, as examples. The instruction specifies a function information block, which is a program representation of a device table entry used by the adapter, to be used in certain situations in establishing the parameters. A store instruction is also provided that stores the current contents of the function information block.
