摘要： A method and apparatus are provided for implementing peripheral component interconnect (PCI) combining function for PCI bridges. A programmable boundary for a combined operation is selected. A write request is received. Responsive to the write request, checking for a combined operation hit is performed. Responsive to an identified combined operation hit, a combined operation is accepted. Checking for the selected programmable boundary for the combined operation is performed. Responsive to identifying the programmable boundary for the combined operation, the combined operation is launched to a destination bus. A programmable timer is identified for the combined operation. Responsive to the programmable timer expiring, the combined operation is launched to a destination bus. The programmable boundary for a combined operation is selected responsive to reading an adapter type and one of combining with a 128-byte boundary, combining with a 256-byte boundary, combining with a 512-byte boundary, or a posted memory write (PMW) is selected.

摘要： A computer-implemented method, apparatus, and computer program product are disclosed for migrating data from a source physical page to a destination physical page. A migration process is begun to migrate data from the source physical page to the destination physical page which causes a host bridge to enter a first state. The host bridge then suspends processing of direct memory access operations when the host bridge is in the first state. The data is migrated from the source physical page to the destination physical page while the host bridge is in the first state.

摘要： A mechanism for temporarily stalling selected Direct Memory Access (DMA) operations in a physical input/output (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 I/O 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 I/O adapter is temporarily stalled while other DMA operations from other I/O adapters to other physical pages in system memory are allowed to continue.
摘要翻译：用于暂时停止物理输入/输出（I / O）适配器中选定的直接内存访问（DMA）操作的机制，以便允许在物理I / O适配器访问的物理页之间迁移数据。当从I / O适配器接收到对系统存储器中的物理页面的DMA的请求时，检查指向物理页面的翻译控制条目（TCE）中正在进行的迁移（MIP）位，其中MIP位指示TCE中引用的物理页面迁移到系统内存中的另一个位置是否正在进行中。如果MIP位指示物理页面的迁移正在进行中，则允许来自I / O适配器的DMA暂时停止，而允许从其他I / O适配器到系统内存中其他物理页面的其他DMA操作继续。

摘要： A method, apparatus, and computer program product are disclosed in a shared processor data processing system for coordinating error reporting for and resetting of a physical I/O adapter that supports virtualization. The physical I/O adapter is virtualized by generating virtual I/O adapters that each represent a portion of the physical I/O adapter. Each one of the virtual I/O adapters is assigned to a different one of client logical partitions. A determination is made regarding whether the physical I/O adapter may have experienced an error. If the physical I/O adapter has experienced an error, all of the client logical partitions are notified about the error and a recovery of the physical I/O adapter is coordinated among all of the client logical partitions by waiting for each client logical partition to acknowledge the error notification before the physical I/O adapter is reset.

摘要： Described is a technique for transferring data between a device controller and a device in a data storage subsystem. The controller has a data buffer through which passes data being transferred to and from the device. The controller communicates with the device by means of low level multi sector Read/Write orders and the data requested by the controller is transferred between device and controller in the form of 32, 64 or 128 byte packets. The device has a relatively small data buffer which can store one packet of data at a time. While one order is executing on the device, the controller is able to issue subsequent orders. One of these orders is an EXTEND order which orders the device to continue reading beyond the data specified in the read order currently executing on the device. The EXTEND order also allows implementation of `back to back` writes.

摘要： An enhanced fibre channel adapter with multiple queues for use by different server processors or partitions. For a non-partitioned server, the OS owns the adapter, controls the adapter queues, and updates the queue table(s). An OS operator can obtain information from the fibre channel network about the fibre channel storage data zones available to the physical fibre channel adapter port and can specify that one or more zones 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 zone or zones of storage data. This queue is given a new World Wide Port Name or new N-Port ID Virtualization identifier, to differentiate this queue from another queue that might have access to a different storage data zone or zones. For a partitioned server, one partition owns the adapter, controls the adapter queues, and updates the queue table(s). The partition management tool can obtain information from the fibre channel network about the fibre channel storage data zones available. A system operator can assign one or more storage zones under a fibre channel storage adapter to a partition. Each partition that has access to a zone or zones under an adapter is given an adapter queue to access the zone or zones. This queue is given a new World Wide Port Name or new N-Port ID Virtualization identifier, to differentiate this queue from another queue that might have access to a different storage data zone or zones.
