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.

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: Congestion is adaptively controlled in a data center Ethernet (DCE) network. Packets are received over at least one virtual lane in the DCE network. An absolute or relative packet arrival rate is computed over a time period. The absolute or relative packet arrival rate is compared to at least a first threshold and a second threshold. If the absolute or relative packet arrival rate increases beyond the first threshold, the packet transmission rate is caused to decrease. If the absolute or relative packet arrival rate is less than a second threshold, the packet transmission rate is caused to increase.
