Abstract: The invention relates to a method for providing an interrupt signal to a first guest operating system. A bus attachment device receives an interrupt signal from a bus connected module with an interrupt target ID identifying a processor assigned for use by the guest operating system as a target processor for handling the interrupt signal. The bus attachment device checks whether the target processor is scheduled for usage by the guest operating system. If the target processor is not scheduled for usage, the bus attachment device forwards the interrupt signal using broadcasting and updates a forwarding vector entry stored in a memory section assigned to a second guest operating system hosting the first guest operating system. The update is used for indicating to the first operating system that there is a first interrupt signal addressed to the interrupt target ID to be handled.

Abstract: A data processing system (210) and a method for handling an input/output store instruction (30), comprising a system nest (18) communicatively coupled to at least one input/output bus (22) by an input/output bus controller (20). The data processing system (210) further comprises at least a data processing unit (216) comprising a core (12), a system firmware (10) and an asynchronous core-nest interface (14). The data processing unit (216) is communicatively coupled to the system nest (18) via an aggregation buffer (16). The system nest (18) is configured to asynchronously load from and/or store data to an external device (214) which is communicatively coupled to the input/output bus (22). The data processing unit (216) is configured to complete the input/output store instruction (30) before an execution of the input/output store instruction (30) in the system nest (18) is completed.

Abstract: An interrupt signal is provided to a target processor. An interrupt signal is received with an interrupt target ID identifying a processor as a target processor for handling the interrupt signal. The interrupt signal is forwarded to the target processor for handling. A translation of the interrupt target ID to a logical processor ID of the target processor is used to address the target processor directly. The bus attachment device updates a directed interrupt signal indicator of a directed interrupt signal vector assigned to the target processor in order to indicate that there is an interrupt signal addressed to the respective interrupt target ID to be handled.
