Abstract: A method and system for substantially avoiding loss of data and enabling continuing connection to the application during an MTU size changing operation in an active network computing device. Logic is added to the device driver, which logic provides several enhancements to the MTU size changing operation/process. Among these enhancements are: (1) logic for temporarily pausing the data coming in from the linked partner while changing the MTU size; (2) logic for returning a “device busy” status to higher-protocol transmit requests during the MTU size changing process. This second logic prevents the application from issuing new requests until the busy signal is removed; and (3) logic for enabling resumption of both flows when the MTU size change is completed. With this new logic, the device driver/adapter does not have any transmit and receive packets to process for a short period of time, while the MTU size change is ongoing.

Abstract: A method, system and computer program product for eliminating the latency in searching for contiguous memory space by an IO DMA request of a device driver. Three new application programming interfaces (APIs) are provided within the operating system (OS) code that allows the device driver(s) to (1) pre-request and pre-allocate the IO DMA address range from the OS during the IPL and maintain control of the address, (2) map a system (virtual/physical) address range to a specific pre-allocated IO DMA address range, and (3) free the pre-allocated IO DMA address space back to the kernel when the space is no longer required. Utilizing these APIs enables advanced IO DMA address mapping techniques maintained by the device drivers, and the assigned/allocated IO DMA address space is no longer fragmented, and the latency of completing the IO DMA mapping is substantially reduced/eliminated.

Abstract: A peripheral component Interconnect (PCI) switch that has at least one control logic device that is capable of changing, on-demand, widths of dedicated buses is provided. The buses are PCI Express buses and thus, are composed of lanes. The control logic device is a lane enable register (LER). Each location in the LER corresponds to a lane of a dedicated bus and is used to enable or disable the corresponding lane. Consequently, widths of dedicated buses are changed by using the switch of the invention to add or subtract one or more lanes from the buses.

Abstract: A computer implemented method, apparatus, and computer usable program code for monitoring health of a data processing system. A determination is made whether a response is received within a first time period in response to an I/O device sending a receive descriptor to the data processing system. A determination is made whether a second time period passes before the receive descriptor becomes available for sending to the data processing system in response to an unavailability of the receive descriptor for sending by the I/O device to the data processing system. A health check is performed on the data processing system if the first time period passes without receiving a response. A health check is performed on the data processing system if the second time period passes without a receive descriptor becoming available to send the data processing system.

Abstract: A plurality of data packets encoded according to a first protocol are received which encapsulate data encoded according to a second protocol. A first source address is extracted from the packets according to the first protocol, it is determined whether or not the first source address is a substantial duplicate of a known assigned address. If it is a duplicate, a second source address is extracted from the encapsulated data according to the second protocol, and the first source address and said second source address are provided in an enhanced error log so that a system administrator may correct the duplicate assigned address. Enhanced embodiments of the invention included analysis of data encapsulated by a third, fourth and subsequent protocols, and automatic determination of each protocol encoding format.
