摘要： Input/output processing is facilitated by readily enabling access to information associated with input/output processing. This information includes status information and measurement data provided by a control unit executing input/output commands. The status and measurement data are provided in a status control block identified in a transport control word, which is further used to specify a location in memory that includes the input/output commands to be executed.

摘要： A bi-directional and full duplex facility for permitting both the IO processor and the Channel to write CCA messages on their respective queues at the same time. IOP messages to the channel are stored on the TO_CHN queue and Channel messages to the IOP on the TO_IOP queue. CCA Queues replace hardware CCAs due to increasing transmission capabilities of current IO processors and Channel processors. Even though the mechanism is similar, the present invention provides some benefits in the use of signaling. The IOP does not have to signal the Channel each time it puts something on its outbound queue. Each queue contains multiple slots. This allows the IOP and Channel to write multiple messages on the targeted queue without encountering a CCA busy signal. The actual queues are now structured in hardware system memory.
摘要翻译：双向和全双工设备，用于允许IO处理器和通道同时在其各自的队列上写入CCA消息。到该通道的IOP消息存储在TO_CHN队列上，并将通道消息存储到TO_IOP队列上的IOP。由于当前IO处理器和通道处理器的传输能力不断增加，CCA队列取代硬件CCA。即使该机制相似，本发明在使用信令方面提供了一些益处。每当它在其出站队列上放置某些东西时，IOP都不必向Channel发出信号。每个队列包含多个插槽。这允许IOP和Channel在目标队列上写入多个消息，而不会遇到CCA忙信号。实际的队列现在由硬件系统内存构成。

摘要： Processing of out-of-order data transfers is facilitated in computing environments that enable data to be directly transferred between a host bus adapter (or other adapter) and a system without first staging the data in hardware disposed between the host bus adapter and the system. An address to be used in the data transfer is determined, in real-time, by efficiently locating an entry in an address data structure that includes the address to be used in the data transfer.

摘要： A computer program product, apparatus, and method for processing a transport control channel program with chain linked branching in an I/O processing system are provided. The method includes receiving a command message at a control unit from an I/O subsystem to perform an I/O operation. The method further includes reading a chain linked flag in the command message indicating that a subsequent command message for the I/O operation follows the command message. The method also includes reading a serialization flag in the command message requesting that device status be returned to the I/O subsystem in order to select the subsequent command message. The method additionally includes executing one or more commands in the command message, and transmitting the device status to the I/O subsystem in response to executing the one or more commands in combination with the serialization flag.
