Abstract: A measurement facility is provided for capturing and presenting fine-grained usage information for adapter functions in an input/output subsystem. Adapter specific input/output traffic is tracked on a per function basis and the results are dynamically presented to the user. This information is useful for performance tuning, load balancing and usage based charging, as examples.

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: 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: 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: 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.
