摘要： In one embodiment, a computer-implemented method for creating redundant system configurations is presented. The computer-implemented method creates a set of virtual function path authorization tables, and receives a request from a requester to provide requested data from a virtual function wherein the virtual function is performed by a single root or a multi-root peripheral component interconnect device. Further a receive buffer is created in a selected address range in a set of addresses ranges as well as a virtual function work queue entry for the virtual function containing an address of the receive buffer in the selected address range. Responsive to a determination that the virtual function is authorized, writing the requested data into the receive buffer of the selected address range in the one or more systems, and responsive to writing the requested data, issuing a notice of completion to the requester.

摘要： Mechanisms for differentiating traffic types in a multi-root PCI Express environment are provided. The mechanisms generate a first mapping data structure that, for each single-root virtual hierarchy in the multi-root data processing system, associates a plurality of traffic classes with a plurality of priority groups and maps each traffic class in the plurality of traffic classes to a corresponding virtual channel in a plurality of virtual channels. Moreover, a second mapping data structure is generated that maps each virtual channel in the plurality of virtual channels to corresponding virtual link in a plurality of virtual links of the multi-root data processing system. Traffic of a particular priority group is routed from a single-root virtual hierarchy to a particular virtual link in the plurality of the virtual links based on the first mapping data structure and second mapping data structure.

摘要： Mechanisms for splitting responsibilities for communicating with an endpoint between a device driver and device driver services are provided. With these mechanisms, the device driver is responsible for managing queues for communicating requests between applications in a logical partition and the endpoint. The device driver further invokes memory management via device driver services. The device driver services are responsible for managing memory accessible by the endpoint, including the address translation and protection table (ATPT) or a root complex and the address translation caches (ATCs) of the endpoint. The device driver services may associate untranslated addresses for data structures used to communicate between a system image and the endpoint. The endpoint may request translations of the untranslated addresses and may cache the translations in the ATCs.

摘要： Mechanisms for communicating with an I/O device or endpoint using a queue data structure and pre-translated addresses associated with the queue data structure are provided. With the mechanisms, a device driver invokes device driver services for initializing address translation and protection table (ATPT) entries in a root complex for the queue data structure. The device driver services return untranslated addresses to the device driver which are in turn provided to the I/O device or endpoint. The I/O device or endpoint may then request a translation of these untranslated addresses and store them in the I/O device or endpoint prior to receiving an I/O operation targeting the queue data structure. The cached translation may be used to directly access the queue data structure from the I/O device or endpoint by bypassing the root complex's address translation facilities.
摘要翻译：提供了使用队列数据结构和与队列数据结构相关联的预翻译地址与I / O设备或端点进行通信的机制。通过这些机制，设备驱动程序调用设备驱动程序服务，用于初始化队列数据结构的根组合中的地址转换和保护表（ATPT）条目。设备驱动程序服务将未翻译的地址返回到设备驱动程序，这些地址依次提供给I / O设备或端点。然后，I / O设备或端点可以在接收到针对队列数据结构的I / O操作之前请求这些非翻译地址的转换并将其存储在I / O设备或端点中。缓存的转换可以用于通过绕过根复合体的地址转换设施直接从I / O设备或端点访问队列数据结构。

摘要： The system and method address the situation where an input/output (I/O) fabric is shared by more than one logical partition (LPAR) and where each LPAR can share with the other LPARs an I/O adapter (IOA). In particular, each LPAR is assigned its own separate address space to access a virtual function (VF) assigned to it such that each LPAR's perception is that it has its own independent IOA. Each VF may be shared across multiple LPARs. Facilities are provided for management of the shared resources of the IOA via a Physical Function (PF) of the IOA by assignment of that PF to an I/O Virtualization Management Partition (IMP). The code running in the IMP acts as a virtual intermediary to the VFs for fully managing the VF error handling, VF reset, and configuration operations. The IMP also acts as an interface to the PF for accessing common VF functionality. Furthermore, the functions of resource assignment and management relative to the VFs and the client partitions that use those VFs, which might normally be done by an entity like a hypervisor, are implemented by this IMP.

摘要： A method, mechanism and computer usable medium is provided for distributing I/O fabric errors to the appropriate root nodes in a multi-root environment. The case where the I/O fabric is attached to more than one root node and where each root can potentially share with the other roots the I/O adapter (IOA) resources which are attached to the I/O is addressed. Additionally, a method, mechanism and computer usable medium is provided by which errors detected in an I/O fabric may be routed to all root nodes which may be affected by the error, while not being reported to the root nodes that will not be affected by those errors. In particular, distributed computing system which uses the PCI Express protocol to communicate over the I/O fabric is addressed.

摘要： A method for communicating with an input/output (I/O) adapter configured to communicate with a locally attached I/O device are provided using cached address translations. With the method, in response to receiving a storage transaction request, a queue element is created in a command queue specifying an untranslated buffer address. The queue element may be retrieved by the I/O adapter and a determination may be made as to whether the queue element contains a read operation command. If so, a translation request may be sent from the I/O adapter to a root complex at substantially a same time as the read operation command is sent to a locally attached external I/O device. The translated address corresponding to the untranslated address of the queue element may be returned and stored in the I/O adapter prior to receiving the data read from the external I/O device.

摘要： A computer-implemented method, apparatus, and computer program product are disclosed in a data processing environment that includes host computer systems that are coupled to adapters utilizing a switched fabric for routing packets between the host computer systems and the adapters. A unique destination identifier is assigned to one of the host computer systems. A portion of a standard format packet destination address is selected. Within a particular packet, the portion is set equal to the unique identifier that is assigned to the host computer system. The particular packet is then routed through the fabric to the host computer system using the unique destination identifier.

摘要： A system and method for migration of single root stateless virtual functions are provided. A Single-Root PCI Configuration Manager (SR-PCIM) provides a system image (SI) with possible virtual function (VF) migration scenarios supported by the endpoint (EP). The SR-PCIM may be instructed that a stateless migration of a VF and its associated application(s) from one SI to another is required. Outstanding requests to the VF are completed and any applications associated with the VF are removed from the SI and the VF is detached from its associated physical function (PF). The SWI may then attach the VF to a target PF which may be in the same or a different EP. The SWI makes the VF available to the SI with which the VF is now associated and the SI configures the VF thereby making it available for use by associated applications.
