Abstract: An article of manufacture, apparatus, and a method for facilitating input/output (I/O) pro-cessing for an I/O operation at a host computer system configured for communication with a control unit. The method includes the host computer system obtaining a transport command word (TCW) for an I/O operation having both input and output data. The TCW specifies a location of the output data and a location for storing the input data. The host computer system forwards the I/O operation to the control unit for execution. The host computer system gathers the output data respon-sive to the location of the output data specified by the TCW, and then forwards the output data to the control unit for use in the execution of the I/O operation. The host computer system receives the input data from the control unit and stores the input data at the location specified by the TCW.

Abstract: Systems, methods and computer program products for providing indirect data addressing at an I/O subsystem of an I/O processing system. The computer program product includes a tangible storage medium readable by a processing circuit and storing instructions for execution by the processing circuit for performing a method. The method includes receiving a control word for an I/O operation. The control word includes an indirect data address for data associated with the I/O operation. The indirect data address includes a starting location of a list of storage addresses that collectively specify the data, the list spans two or more non-contiguous storage locations. Data is gathered responsive to the list. The gathered data is transmitted to a control unit in the I/O processing system.

Abstract: A state of an input/output (I/O) operation in an I/O processing system is determined. A request for performing the I/O operation is received from an I/O operating system at a channel subsystem and forwarded to a control unit controlling an I/O device for executing the I/O operation. After a predetermined amount of time passes without receiving indication from the control unit that the I/O operation is completed, an interrogation request is received at the channel subsystem from the I/O operating system for determining the state of the I/O operation. An interrogation command is sent from the channel subsystem to the control unit. A response is received from the control unit, the response indicates a state of the I/O device executing the I/O operation, a state of the control unit controlling the I/O device executing the I/O operation, and the state of the I/O operation being executed.

Abstract: Se proporciona una instrucción para establecer diversos parámetros operacionales para un adaptador. Estos parámetros incluyen parámetros de interrupción de adaptador, parámetros de traducción de dirección de entrada/salida, reajuste de indicaciones de error, ajuste de parámetros de medición y ajuste de un control de intercepción, como ejemplos. La instrucción específica un bloque de información de función, que es una representación del programa de una entrada de tabla de dispositivo utilizada por el adaptador, para utilizarse en ciertas situaciones para establecer los parámetros. Una instrucción de almacenar también se proporciona que almacena los contenidos actuales del bloque de información de función.

Abstract: Una o más solicitudes de interrupción con señal de mensaje de uno o más adaptadores de entrada/salida, E/S (I/O = input/output) se convierten en notificaciones de evento de adaptador E/S. Cada notificación de evento de adaptador E/S incluye el ajuste de uno o más indicadores específicos en la memoria del sistema y una solicitud de interrupción, la primera de las cuales resulta en una solicitud de interrupción de adaptador E/S pendiente. Mientras que una solicitud para una interrupción de adaptador E/S está pendiente, se convierten subsecuentes solicitudes de interrupción con señal de mensaje a notificaciones de evento de adaptador E/S, pero no resultan en solicitudes adicionales para interrupciones de adaptador E/S.

Abstract: One or more message signaled interruption requests from one or more input/output (I/O) adapters are converted to I/O adapter event notifications. Each I/O adapter event notification includes the setting of one or more specific indicators in system memory and an interruption request, the first of which results in a pending I/O adapter interruption request. While a request for an I/O adapter interruption is pending, subsequent message signaled interruption requests are converted to I/O adapter event notifications, but do not result in additional requests for I/O adapter interruptions.
