A computer-implemented method is provided for analyzing and classifying automobile sounds. The computer-implemented method includes causing a receiver to receive an audio input, determining whether the audio input is distinct from sounds stored in a library and breaking the audio input up into constituent segments in an event the audio input is distinct from sounds stored in the library. The computer-implemented method further includes determining whether any of the constituent segments are unassociated with known sources and determining whether present conditions, which were in effect during the receiving of the audio input, are similar to prior conditions, which were in effect during a previous audio input reception, in an event constituent segments are unassociated with the known sources. In addition, the computer-implemented method includes matching those constituent segments unassociated with the known sources to remotely stored or recognized sounds in an event the present and prior conditions are similar.

A computer implemented method, apparatus, and computer usable program code for assuring data integrity is shown. A partition receives a request to execute an executable file from a source external to the partition. A memory region is created within the partition. The partition or service interface makes an authentication determination. The partition executes an executable file in the memory region based on the request, provided there is a positive authentication determination.

A computer-implemented method, apparatus, and computer usable program code are disclosed for migrating a virtual adapter from a source physical adapter to a destination physical adapter in a data processing system where multiple host computer systems share multiple adapters and communicate with those adapters through a PCI switched-fabric bus. The virtual adapter is first caused to stop processing transactions. All in-flight transactions that are associated with the virtual adapter are then captured. The configuration information that defines the virtual adapter is moved from the source physical adapter to the destination physical adapter. The in-flight transactions are then restored to their original locations on the destination virtual adapter. The virtual adapter is then restarted on the destination physical adapter such that the virtual adapter begins processing transactions.

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.

Broadcast of shared I/O fabric error messages in a multi-host environment to all affected root nodes

Routing between multiple hosts and adapters in a PCI environment is provided by a method and system. A Destination Identification (DID) field is inserted in a field of the PCI bus address (PBA) of transaction packets dispatched through PCI switches. A particular DID is associated with a particular host or system image, and thus identifies the physical or virtual end point of the packets. The method and system may track connections such that when particular host of a root node becomes connected to a specified switch, a PCI Configuration Master (PCM), residing in one of the root nodes, is operated to enter a destination identifier or DID into a table. The DID is then inserted in the PBA of packets directed through the specified switch from the particular host to one of the adapters.

Creation and management of routing table for PCI bus address based routing with integrated DID

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.

The present invention provides mechanisms that enable application instances to pass block mode storage requests directly to a physical I/O adapter without run-time involvement from the local operating system or hypervisor. In one aspect of the present invention, a mechanism is provided for handling user space creation and deletion operations for creating and deleting allocations of linear block addresses of a physical storage device to application instances. For creation, it is determined if there are sufficient available resources for creation of the allocation. For deletion, it is determined if there are any I/O transactions active on the allocation before performing the deletion. Allocation may be performed only if there are sufficient available resources and deletion may be performed only if there are no active I/O transactions on the allocation being deleted.

A mechanism is provided that enables user space middleware or applications to pass file name based storage requests directly to a physical I/O Adapter without run-time involvement from the local Operating System (OS). A mechanism is provided for using a file protection table (FPT) data structure, which may include a file name protection table (FNPT) and file extension protection table (FEPT), to control user space and out of user space Input/Output (I/O) operations. In addition, a mechanism is provided for managing the FPT based on user space operations to create, query, modify and delete entries in the FPT.

Processing user space operations directly between an application instance and an I/O adapter

Having detected an anomalous fault in a peripheral I/O slot, a processor entity may need to perform some remedial action, wherein the peripheral slot may have a fault line. First a voltage may be detected on the slot. Processor entity may set a fault if a voltage is found. A hotplug controller which may provide outputs that the processing entity may store as a fault syndrome word. The service processor or operating system, either during initial program load, or at another time, may detect that the fault could be a false fault depending on a set of predefined conditions and following the mechanism described here can then clear the fault earlier set. If an action from a previous device list is set, then there may be a clearing of the voltage fault based on determining that the action is set.
