摘要： An apparatus, program product and method in which a memory address space is allocated non-uniformly to IO resources in a memory mapped IO fabric based upon the locations of individual IO endpoints to which such IO resources are coupled. In a PCI-based environment, for example, PCI adapters are allocated memory address ranges in a PCI bus address space based upon the locations of the particular slots within which the PCI adapters are mounted.

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： Methods, systems, and articles of manufacture for communicating with an I/O processor (IOP) are provided. Polling of message queue pointers is utilized to detect the occurrence of certain message queue related events, rather than rely on interrupts generated by the IOP. The polling may decrease the disruptive effects of IOP generated interrupts. In an effort to minimize the latency associated with detecting IOP related events, the polling may be initiated frequently by an operating system task dispatcher. In an effort to minimize context switches, the task dispatcher may schedule the processing of upstream messages detected while polling to coincide with naturally occurring task swaps.

摘要： A method, which may be embodied upon a computer readable medium and executed by a processor, for PCI IO using PCI device memory mapping in a logically partitioned system. The method may include the steps of detecting PCI devices in a bus walk initialization process, and associating a pseudonym address range with each PCI device detected in the bus walk initialization process. The method may further include updating PCI device IO resources for each PCI device detected with the associated pseudonym address range, and accessing the detected PCI devices with a device driver using the pseudonym address range stored in the PCI device IO resources.

摘要： An apparatus, system and method permitting a variety of reset procedures and corresponding reset states. A device reset control register is provided for each I/O device adapter in single function or multifunction devices. The device reset control registers permit a greater degree of control over single function devices, multifunction device as a whole and individual device functions within a multifunction device. A device immediate status register synchronizes the various reset procedures. A logical power on reset procedure, a directed unit reset procedure and a directed interface reset procedure utilize the greater degree of control that the device reset control registers provide to force the I/O device adapter, single function device or multifunction device into a corresponding logical power on reset state, a directed unit reset state or a directed interface reset state. Each of these reset states is well-defined and has the advantage of predictable behavior during and after execution of the corresponding reset procedure. A built-in self-test procedure is also defined that sequentially examines each function associated within a multifunction device connected to the local bus to coordinate the initiation, execution and completion of built in self-tests.

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： A partition manager includes an I/O reconfiguration mechanism and a logical partition suspend/resume mechanism that work together to perform autonomic I/O reconfiguration in a logically partitioned computer system. When I/O reconfiguration is required, the affected logical partitions are suspended, the I/O is reconfigured, and the affected logical partitions are resumed. Because the logical partitions are suspended during I/O reconfiguration, any ghost packet that may occur when the I/O is reconfigured is ignored.
