摘要： A method, computer program product, and distributed data processing system that allows a single physical I/O adapter, such as a PCI, PCI-X, or PCI-E adapter, to track performance and reliability statistics per virtual upstream and downstream port, thereby allowing a system and network management to be performed at finer granularity than what is possible using conventional physical port statistics, is provided. Particularly, a mechanism of managing per-virtual port performance metrics in a logically partitioned data processing system including allocating a subset of resources of a physical adapter to a virtual adapter of a plurality of virtual adapters is provided. The subset of resources includes a virtual port having an identifier assigned thereto. The identifier of the virtual port is associated with an address of a physical port. A metric table is associated with the virtual port, wherein the metric table includes metrics of operations that target the virtual port.

摘要： A method, computer program product, and distributed data processing system that allows a single physical I/O adapter, such as a PCI, PCI-X, or PCI-E adapter, to validate that a direct memory access address referenced by an incoming I/O transaction that was initiated through a memory mapped I/O operation are associated with a virtual adapter or virtual resource that is referenced by the incoming memory mapped I/O operation is provided. Specifically, the present invention is directed to a mechanism for sharing conventional PCI (Peripheral Component Interconnect) I/O adapters, PCI-X I/O Adapters, PCI-Express I/O Adapters, and, in general, any I/O adapter that uses a memory mapped I/O interface for communications. A single physical I/O adapter validates that one or more direct memory access addresses referenced by an incoming I/O transaction initiated through a memory mapped I/O operation are associated with a virtual adapter or virtual resource that is referenced by the incoming memory mapped I/O operation.

摘要： A mechanism for handling event notifications or interrupts in a logically partitioned computing system having IO adapters that support adapter virtualization are provided. A virtual adapter associated with a physical IO adapter detects an event, identifies a logical partition associated with the event, and writes an event notification entry in a partition interrupt control block (PICB) of the logical partition memory space. The virtual adapter notifies shared control point logic on the physical IO adapter of the update to the PICB which may then write an entry to a logical partition manager interrupt control block (LPAR manager ICB) identifying the update to the PICB and the operating system associated with the PICB. The LPAR manager may then inform the operating system of the logical partition of the updates to the PICB which may then read the entries in the PICB, process them and inform appropriate application instances of the events.

摘要： An apparatus and method for reordering data at a data destination is provided. The apparatus and method provides dynamic, adaptive management of receive buffers in a host channel adapter while recovering on the fly the order of data sent over a medium that does not preserve order. In an exemplary embodiment, the method and apparatus provides a method and apparatus of reordering data of a data transmission received from a source device. The method and apparatus receives, in a data transfer buffer, a data packet transmitted over a connection associated with the source device and determines if the connection requires reordering of data packets. If the connection requires reordering of data packets, the data packet is transferred from the data transfer buffer to a reorder buffer and a reorder state cache is updated to reflect the transfer of the data packet to the reorder buffer. In response to receipt of a request to transfer data from the reorder buffer to the host memory, a next data packet sequence number is fetched from the reorder state cache and a position in the reorder buffer of the data associated with the next data packet sequence number entry is identified. The data is at this identified position is then transferred to the host memory.

摘要： A method, system and program for controlling access to memory areas within a computer are provided. The invention comprises placing a first Bind Work Queue Element (WQE) at the head of a work queue, wherein the first Bind WQE defines parameters associated with a first Memory Window. A set of Work Requests is then placed on the work queue, behind the first Bind WQE wherein the work requests invoke operations that access the first Memory Window. A second Bind WQE is then placed on the work queue, behind the first set of Work Requests. This second Bind WQE defines parameters associated with a second Memory Window. A second set of Work Requests is placed on the work queue behind the second Bind WQE and invoke operations that access the second memory window. The Memory Windows can be associated with a common Memory Region and have different addresses and lengths or different access rights. In another embodiment, the first and second Memory Windows can be associated with different Memory Regions.
