    摘要: Method, apparatus and system for isolating input/output adapter interrupt domains in a data processing system. The data processing system includes a plurality of input/output adapters, and isolation of interrupt resources available to the input/output adapters is controlled by functionality in a host bridge that connects the plurality of 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: A mechanism for temporarily stalling selected Direct Memory Access (DMA) operations in a physical I/O adapter in order to permit migration of data between physical pages that are subject to access by the physical I/O adapter. When a request for a DMA to a physical page in system memory is received from an input/output adapter, a migration in progress (MIP) bit in a translation control entry (TCE) pointing to the physical page is examined, wherein the MIP bit indicates whether migration of the physical page referenced in the TCE to another location in system memory is currently in progress. If the MIP bit indicates a migration of the physical page is in progress, the DMA from the input/output adapter is temporarily stalled while other DMA operations from other input/output adapters to other physical pages in system memory are allowed to continue.

    摘要: An enhanced SCSI storage adapter with multiple queues for use by different server processors or partitions. For a non-partitioned server, the operating system (OS) owns the SCSI storage adapter, controls the adapter queues, both creation of and changes to the queues, and updates the queue table(s) in the storage adapter with queue address information, device list, message signaled interrupt (MSI) information and optional queue priorities. An OS operator can specify that one or more SCSI devices can be accessed by a specific processor or group of processors. The processor or group of processors is given an adapter queue to access the SCSI device or devices. For a partitioned server, one partition, which may be a hosting partition, owns the SCSI storage adapter, controls the adapter queues, both creation of and changes to the queues, and updates the queue table(s) in the storage adapter with queue address information, device list, message signaled interrupt (MSI) information and optional queue priorities. A system operator can assign one or more SCSI devices under a storage adapter to a partition. Each partition that has access to a SCSI device(s) under a SCSI adapter is given an adapter queue to access the device(s).

    摘要: A mechanism that allows a single physical I/O adapter, such as a PCI, PCI-X, or PCI-E adapter, to perform I/O transactions using the PCI host bus, device, and function numbers to validate that an I/O transaction originated from the proper host is provided. Additionally, a method for facilitating identification of a transaction source partition is provided. An input/output transaction that is directed to a physical adapter is originated from a system image of a plurality of system images. The host data processing system adds an identifier of the system image to the input/output transaction. The input/output transaction is then conveyed to the physical adapter for processing of the input/output transaction.
