    摘要： Method, apparatus and system for isolating input/output adapter error domains in a data processing system. Errors occurring in one input/output adapter are isolated from other input/output adapters of the data processing system by functionality in a host bridge that connects the input/output adapters to a system bus of the data processing system, thus permitting the use of low cost, industry standard switches and bridges external to the host bridge.

    摘要： An apparatus, program product and method propagate errors detected in an IO fabric element from an IO fabric that is used to couple a plurality of endpoint IO resources to processing elements in a computer. In particular, such errors are propagated to the endpoint IO resources affected by the IO fabric element in connection with recovering from the errors in the IO fabric element. By doing so, a device driver or other program code used to access each affected IO resources may be permitted to asynchronously recover from the propagated error in its associated IO resource, and often without requiring the recovery from the error in the IO fabric element to wait for recovery to be completed for each of the affected IO resources. In addition, an IO fabric may be dynamically configured to support both recoverable and non-recoverable endpoint IO resources. In particular, IO fabric elements within an IO fabric may be dynamically configured to enable machine check signaling in such IO fabric elements in response to detection that an endpoint IO resource is non-recoverable in nature. The IO fabric elements that are dynamically configured as such are disposed within a hardware path that is defined between the non-recoverable resource and a processor that accesses the non-recoverable resource.

    摘要翻译： 装置，程序产品和方法将用于将多个端点IO资源耦合到计算机中的处理元件的IO架构在IO结构元素中检测到的错误传播。 特别地，这些错误被传播到由IO结构元素影响的端点IO资源以及从IO结构元素中的错误的恢复。 通过这样做，可以允许用于访问每个受影响的IO资源的设备驱动程序或其他程序代码从其关联的IO资源中的传播错误异步恢复，并且通常不需要从IO架构元素中的错误中恢复以等待 以便为每个受影响的IO资源完成恢复。 此外，IO结构可以动态配置为支持可恢复和不可恢复的端点IO资源。 特别地，IO结构中的IO结构元素可以被动态地配置成使得在这种IO结构元素中的机器检查信令能够响应于端点IO资源在本质上是不可恢复的检测。 被动态地配置的IO结构元素被布置在在不可恢复资源和访问不可恢复资源的处理器之间定义的硬件路径中。

    摘要： Method, apparatus and system for controlling input/output adapter data flow operations in a data processing system that includes at least one of a traffic class mechanism in conjunction with virtual channel resources so as to be able to associate Load/Store and DMA flows to/from an input/output adapter, and a relaxed ordering mechanism for associating a relaxed ordering bit to Load/Store operations to an input/output adapter. Functionality for controlling the input/output adapter data flow is provided in a host bridge that connects the input/output adapter to a system bus of the data processing system.

    摘要： A method and system are provided for dynamically informing an operating system (OS) of a distributed computer system, when a (new) device is added on the network. An OS registers with the subnet administrator (SA) to be notified when a new component is added to the subnet and placed in a partition to which the OS has access. The subnet manager (SM) initializes and configures the new component that is added and, through the partition manager, associates the component to one or more partitions of the subnet. The SA then notifies the OSs with access to the partition(s) to which the component is associated and that have a right to access the new component that the new component is available to the OS. Following, the OS updates a database of available components to include the new component and establishes communication with the new component.

    摘要： A method in a network computing system for managing configuration information for a set of components in a network computing system. The configuration information is stored for the set of components in the network computing system to form stored configuration information. In the depicted examples, the components may be nodes or devices within nodes. Current configuration is obtained in response to a power cycle. The current configuration information is compared with the stored configuration information to form a comparison. The stored configuration information is updated if a difference is present in the comparison. The stored configuration information is used to configure the components when a power cycle occurs.
