Abstract: An address provided in a request issued by an adapter is converted to an address directly usable in accessing system memory. The address includes a plurality of bits, in which the plurality of bits includes a first portion of bits and a second portion of bits. The second portion of bits is used to index into one or more levels of address translation tables to perform the conversion, while the first portion of bits are ignored for the conversion. The first portion of bits are used to validate the address.

Abstract: Various address translation formats are available for use in obtaining system memory addresses for use by requestors, such as adapter functions, in accessing system memory. The particular address translation format to be used by a given requestor is pre-registered in a device table entry associated with that requestor.

Abstract: An adapter is enabled for use. The enabling includes assigning one or more address spaces to the adapter, based on a request. For each address space assigned to the adapter, a corresponding device table entry is assigned. When the adapter is no longer needed, it is disabled and the assigned device table entries become available.

Abstract: The conditions under which adapter interruptions are made pending are controlled. Responsive to an interruption being presented to an operating system, subsequent interruptions are suppressed on all central processing units in the configuration. The operating system processes the interruption, including examining and processing indicators of reported events until the operating system discontinues the suppression. This enables the operating system to control the number of pending interruptions and the number of processors processing those interruptions.

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.
