摘要： A method of managing memory mapped input output operations to an alternate address space comprising: executing a first instruction directed to a first memory mapped input output alternate address space of a machine associated with a first adapter to allocate a resource associated with the first adapter to a process in accordance with a definition of a z/Architecture; wherein a selected process issues at least one of a load and a store instruction executed in a problem state of the machine to a selected address location of a selected resource. The method further includes ensuring that the selected resource corresponds with the allocated resource and determining that the selected process corresponds with the process to which the resource is allocated.

摘要： A communication port of a communications interface of an information handling system comprises a plurality of virtual ports. A first command is issued to obtain information indicating a number of images of virtual ports supportable by the communications interface. A second command is then issued requesting the communications interface to virtualize the communication port. In response to the second command, one or more virtual switches are then configured to connect to the communication port, each virtual switch including a plurality of virtual ports, such that the one or more virtual switches are configured in a manner sufficient to support the number of images of virtual ports indicated by the obtained information. Thereafter, upon request via issuance of a third command, a logical link is established between one of the virtual ports of one of the virtual switches and a communicating element of the information handling system.

摘要： A processor node of a network is provided which includes one or more processors and a virtualized channel adapter. The virtualized channel adapter is operable to reference a table to determine whether a destination of the communication is supported by the virtualized channel adapter. When the destination is supported for routing via hardware, the virtualized channel adapter is operable to route the communication via hardware to at least one of a physical port and a logical port of the virtualized channel adapter. Otherwise, when the destination is not supported for routing via hardware, the virtualized channel adapter is operable to route the communication via firmware to a virtual port of the virtualized channel adapter. A corresponding method and a recording medium having information recorded thereon for performing such method are also provided herein.

摘要： A Host Channel Adapter supporting a plurality of Logical Partitions is provided. A Subnet Manager, having an associated aliased Queue Pair, may run in a Logical Partition. A single physical subnet management Queue Pair and its associated firmware are provided for each physical port in the Host Channel Adapter. If a packet is to be routed to a Subnet Manager residing in a Logical Partition, the packet is enqueued on the physical port's send queue for transmission to the aliased Queue Pair for the Subnet Manager. The Host Channel Adapter hardware loops the packet back to the aliased Queue Pair in the appropriate Logical Partition. The aliased Queue Pair is also capable of transmitting packets that are looped back to a Hypervisor Subnet Management Agent.

摘要： A method, apparatus, and computer program product are disclosed in a data processing system for migrating data pages subject to DMA access by temporarily disabling selected DMA operations within a physical I/O adapter. A determination is made as to whether to disable data access DMA capabilities of the physical I/O adapter. An operating mode of the physical I/O adapter is set to a particular mode utilizing a mode bit according to the determination of whether to disable data access DMA capabilities. Only data access DMA capabilities of the physical I/O adapter are disabled when the mode bit is set. Administrative services operations continue to be performed by the physical I/O adapter when the data access DMA capabilities of the physical I/O adapter are disabled.
