Abstract: Management of storage used by pageable guests of a computing environment is facilitated. An enhanced suppression-on-protection facility is provided that enables the determination of which level of protection (host or guest) caused a fault condition, in response to an attempted storage access.

Abstract: A program (e.g., an operating system) is provided a warning that it has a grace period in which to perform a function, such as cleanup (e.g., complete, stop and/or move a dispatchable unit). The program is being warned, in one example, that it is losing access to its shared resources. For instance, in a virtual environment, a guest program is warned that it is about to lose its central processing unit resources, and therefore, it is to perform a function, such as cleanup.

Abstract: A system and method of implementing a modified priority routing of an input/output (I/O) interruption. The system and method determines whether the I/O interruption is pending for a core and whether any of a plurality of guest threads of the core is enabled for guest thread processing of the interruption in accordance with the determining that the I/O interruption is pending. Further, the system and method determines whether at least one of the plurality of guest threads enabled for guest thread processing is in a wait state and, in accordance with the determining that the at least one of the plurality of guest threads enabled for guest thread processing is in the wait state, routes the I/O interruption to a guest thread enabled for guest thread processing and in the wait state.

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.

Abstract: Un método de gestión de peticiones de interrupción en un entorno informático, caracterizado por comprender los pasos de: en respuesta a ejecutar una operación de interrupciones de registro de instrucción Modificar los Controles de Función de PCI (MPFC) que especifica un gestor de función de un adaptador, especificar (601) en una tabla localizada en un centro de entrada/salida (I/O) acoplado al adaptador, una ubicación en la memoria del sistema de un vector de bit de interrupción de adaptador (AIBV) del adaptador, el AIBV incluido en una formación de uno o más AIBV y una ubicación en la memoria del sistema de un bit de resumen de interrupción de adaptador (AISB) de una formación de AISB; recibir (603) desde el adaptador una petición de interrupción; y en respuesta a la petición recibida, fijar (605) por el centro de I/O un indicador en el AIBV que indica un tipo de evento desde el adaptador y fijar (606) el AISB que indica que un indicador está fijado en el AIBV.
