摘要： A hypervisor, during device discovery, has code which can examine the south-side management data structure in an adapter's configuration space and determine the type of device which is being configured. The hypervisor may copy the south-side management data structure to a hardware management console (HMC) and the HMC can populate the data structure with south-side data and then pass the structure to the hypervisor to replace the data structure on the adapter. In another embodiment the hypervisor may copy the data structure to the HMC and the HMC can instruct the hypervisor to fill-in the data structure, a virtual function at a time, with south-side management data associations. The administrator can assign south-side data, such as a MAC address for a virtual instance of an Ethernet device, to LPARs sharing the adapter. Thus, a standard way to manage the south-side data of virtual functions is provided.

摘要： A computer-implemented method, apparatus, and computer program product are disclosed for routing error messages in a multiple host computer system environment to only those host computer systems that are affected by the error. The environment includes multiple host computer systems that share multiple devices utilizing a switched fabric. An error is detected in one of the devices. Routing tables that are stored in fabric devices in the fabric are used to identify ones of the host computer systems that are affected by the error. An error message that identifies the error is routed to only the identified ones of the host computer systems.

摘要： Mechanisms for migration stateless virtual functions from one virtual plane to another are provided. When a migration of a source virtual function to a destination virtual function in another virtual plane is to be performed, a source single root PCI manager (SR-PCIM) is first interrupted by a multiple root PCI manager (MR-PCIM). Configuration information that defines the source virtual function is then redefined on the destination virtual function for this stateless migration. A function level reset may then be performed on the source virtual function. The destination SR-PCIM may be interrupted by the MR-PCIM with an interrupt for the destination virtual function. A function level reset may then be performed on the destination virtual function. The destination virtual function state may then be changed to an “active” state such that the migrated virtual function begins processing transactions.

摘要： Mechanisms are provided for implementing a multi-root PCI manager (MR-PCIM) in a multi-root I/O virtualization management partition (MR-IMP) to control the shared functionality of an multi-root I/O virtualization (IOV) enabled switch fabric and multi-root IOV enabled I/O adapter (IOA) through the base functions (BF) of the switches and IOAs. A hypervisor provides device-independent facilities to the code running in the I/O Virtualization Management Partition (IMP), Multi-Root (MR)-IMP and client partitions. The MR-IMP may include device specific code without the hypervisor needing to sacrifice its size, robustness, and upgradeability. The hypervisor provides the virtual intermediary functionally for the sharing and control of the switch and IOA's control functions.

摘要： A computer-implemented method, apparatus, and computer program product are disclosed for bus/device/function (BDF) translation and routing of communications packets through a fabric that utilizes PCI switches. Identifiers are included in communications packets that are routed between a host and an I/O adapter using a PCI fabric to which the host and the I/O adapter are coupled. Destination identifiers that are included in first communications packets that are received by edge switches, which are connected directly to said host or directly connected to said I/O adapter, are translated before routing the communications packets out of the edge switches. Second communications packets that are received by internal switches, which are not directly connected to the host or directly connected to the I/O adapter, are routed without translating destination identifiers that are included in the second communications packets.

摘要： Method and system for address routing in a distributed computing system, such as a distributed computing system that uses PCI Express protocol to communicate over an I/O fabric. A destination identifier is provided to identify a physical or virtual host or end point. When a physical or virtual host or end point receives a PCI data packet it compares a list of source identifiers with destination identifiers to determine if a source identifier included in the transaction packet is associated with a destination identifier included in the transaction packet to determine if the transaction packet has a valid association. If the transaction packet has a valid association, it is routed to the target device. The present invention enables each host that attaches to PCI bridges or switches and shares a set of common PCI devices to have its own PCI 64-bit address space and enables the routing of PCI transaction packets between multiple hosts and adapters, through a PCI switched-fabric bus using a destination identifier.

摘要： A method and apparatus is provided for routing error messages in a distributed computer system comprising multiple root nodes, and further comprising one or more PCI switches and one or more I/O adapters, wherein each root node includes one or more system images. In one useful embodiment, a method is provided for routing I/O error messages to root nodes respectively associated with the errors contained in the messages. The method includes detecting occurrence of an error at a specified one of the adapters, wherein the error affects one of the system images, and generating an error message at the specified adapter. The method further comprises routing the error message from the specified adapter to the particular root node that includes the affected system image. The error message is then selectively processed at the particular root node, in order to identify the affected system image. Usefully, the step of routing the error message includes using a bus/device/function number associated with the error, together with a routing table located in one of the PCI switches, to route the error message to the correct root node and system image.

摘要： A system and method for communication between host systems using a queuing system and shared memories are provided. Memory address spaces of the host systems are initialized such that endpoints may be accessible by root complexes across host systems. These memory address spaces may then be used to allow system images, and their corresponding applications, associated with these root complexes to communicate with the endpoints using a queuing system. Such a queuing system may comprise queue structures having doorbell structures for providing information about the queue entries in the queue structures. Queue elements may be generated and added to the queue structures, and the doorbell structure may be written to, in order to thereby inform an endpoint or root complex that queue elements are available for processing. DMA operations may be performed to retrieve the queue elements and the data corresponding to the queue elements.

摘要： A system and method for initializing shared memories for sharing endpoints across a plurality of root complexes is provided. In one illustrative embodiment, a multi-root PCIe manager (MR-PCIM) initializes the shared memory between root complexes and endpoints by discovering the PCIe switch fabric by traversing all the links accessible through the interconnected switches of the PCIe switch fabric. As the links are traversed, the MR-PCIM compares information obtained for each of the root complexes and endpoints to determine which endpoints and root complexes reside on the same blade. A virtual PCIe tree data structure is then generated that ties the endpoints available on the PCIe switch fabric to each root complex. The MR-PCIM, or a single-root PCIe manager (SR-PCIM), may then assign each endpoint and root complex a base and limit within the PCIe memory address space the endpoint belongs to.

摘要： System and method for managing routing of data in a distributed computing system, such as a distributed computing system that uses PCI Express protocol to communicate over an I/O fabric. A physical tree that is indicative of a physical configuration of the distributed computing system is determined, and a virtual tree is created from the physical tree. The virtual tree is then modified to change an association between at least one source device and at least one target device in the virtual tree. A validation mechanism validates the changed association between the at least one source device and the at least one target device to enable routing of data from the at least one source device to the at least one target device.
