    摘要: Method, apparatus and system for isolating input/output adapter error domains in a data processing system. Errors occurring in one input/output adapter are isolated from other input/output adapters of the data processing system by functionality in a host bridge that connects the 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: Method and apparatus for providing failover operation for a connection between a first PCIE bridge and a first input/output (IO) device are provided. A first set of bussed bits is exchanged between the first PCIE bridge and the first IO device over a first link using a first set of lanes of the first PCIE bridge. In response to detecting the failure in the first link, the first set of bussed bits is exchanged between the first PCIE bridge and the first IO device using an unused portion of a second link connecting a second PCIE bridge and a second IO device.

A first set of bussed bits is exchanged between the first PCIE bridge and the first IO device over a first link using a first set of lanes of the first PCIE bridge. In response to detecting a failure in the first link, at a PCIE bridge end, the first set of lanes is swapped with a second set of lanes of the first PCIE bridge for exchanging a second set of bussed bits between the first PCIE bridge and the first IO device over a second link using the second set of lanes, the second link connecting a second PCIE bridge with a second IO device. In response to detecting the failure in the first link, at an IO device end, the first set of lanes is switched with the second set of lanes for exchanging the second set of bussed bits between the first PCIE bridge and the first IO device over the second link using the second set of lanes.

    摘要: A data storage subsystem and method for transferring data from a storage subsystem to a connected host data processing system are described. The subsystem comprises a device controller connected to one or more direct access storage devices e.g. disk drives. The host data processing system issues data transfer commands to the subsystem to initiate transfer of data between the host processing system and the device(s) associated with the data storage subsystem. Read/write data is transferred directly from device to host via a buffer controller. For a read operation, the read command from the host data processing system specifies the data to be transferred and the start address in host memory to which the data should be sent. The device controller of the data storage subsystem is capable of respecifying or amending the start address specified by the host in the rad command. This provides a performance bonefit for split data transfers. In addition, if an error occurs during a read operation, the device controller of the data storage subsystem can specify the host address to which the replacement data should be sent.

    摘要: A method and system for controlling the display of data in a data processing system that includes a main processor, a memory subsystem, and an Input/Output subsystem which includes an I/O Channel Controller for managing traffic on an I/O bus having an attached co-processor and a plurality of I/O devices including display devices with different reserved I/O address space. The main processor can establish different display modes for displays having different reserved I/O address space, which generally indicates different display types. In one mode, a display is assigned exclusively to the main processor and attempted data transfers by the co-processor to that display are suppressed. In a second mode, a display is time-shared between processors by establishing a virtual video buffer in main memory which is written into by one processor when the other processor has control of the display device. The contents of the virtual and real buffer are swapped whenever the display is reassigned to the other processor. In the third mode, co-processor data in the virtual buffer can be "windowed" onto the display device when it is assigned to the main processor. In the fourth mode, a display assigned to the co-processor displays data being run by code that is written to the displayed on a display device with a different pel resolution. The main processor does a pel conversion operation on the data in the process of transferring the data from the virtual buffer to the real buffer.

The main processor can establish different display modes for displays having different reserved I/O address space, which generally indicates different display types. In one mode, a display is assigned exclusively to the main processor and attempted data transfers by the co-processor to that display are suppressed. The display control means is based on logic circuitry associated with the co-processor for trapping instructions having addresses within the range of those reserved for the display devices. The logic enables normal writes and reads to the video buffer to be suppressed or relocated to the virtual buffer, depending on the mode established by the main processor. A circular queue is established in memory to enable the main processor to selectively individually update the video buffer with the changes that have been made to the virtual buffer.
