Abstract: Ein Datenverarbeitungssystem (210) und ein Verfahren zur Handhabung einer Eingabe-/ Ausgabe-Speicheranweisung (30), das ein Systemnest (18) aufweist, welches durch einen Eingabe-/Ausgabebuscontroller (20) mit mindestens einem Eingabe-/Ausgabebus (22) verbunden ist. Eine Datenverarbeitungseinheit (216) ist über einen Aggregationspuffer (16) mit dem Systemnest (18) verbunden. Ein Systemnest (18) ist so konfiguriert, dass es Daten aus/in mindestens einer externen Einheit (214) asynchron lädt und/oder speichert. Die Datenverarbeitungseinheit (216) ist so konfiguriert, dass sie die Eingabe-/Ausgabe-Speicheranweisung (30) abschließt, bevor eine Ausführung der Eingabe-/Ausgabe-Speicheranweisung (30) in dem Systemnest (18) abgeschlossen ist. Eine asynchrone Kern-Nest-Schnittstelle (14) weist ein Eingabe-/Ausgabe-Statusarray (44) mit mehreren Eingabe-/ Ausgabe-Statuspuffern (24) auf. Eine System-Firmware (10) weist einen Wiederholungspuffer (52) auf, und der Kern (12) weist eine Analyse- und Wiederholungslogik (54) auf.

Abstract: A Load to Block Boundary instruction is provided that loads a variable number of bytes of data into a register while ensuring that a specified memory boundary is not crossed. The boundary may be specified a number of ways, including, but not limited to, a variable value in the instruction text, a fixed instruction text value encoded in the opcode, or a register based boundary.

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 input/output store instruction is handled. A data processing system includes a system nest coupled to at least one input/output bus by an input/output bus controller. The data processing system further includes at least a data processing unit including a core, system firmware and an asynchronous core-nest interface. The data processing unit is coupled to the system nest via an aggregation buffer. The system nest is configured to asynchronously load from and/or store data to at least one external device which is coupled to the at least one input/output bus. The data processing unit is configured to complete the input/output store instruction before an execution of the input/output store instruction in the system nest is completed. The asynchronous core-nest interface includes an input/output status array with multiple input/output status buffers.

Abstract: A facility is provided for collecting time-slice-instrumentation information during processing unit execution. The facility counts, at least in part, occurrence of a specified processing unit event during a time-slice of processing unit execution. The counted events occurring during a first interval of execution and a second interval of execution of the time-slice are retained. The first interval of execution is earlier in the time-slice than the second interval of execution, and the counted events facilitate adjusting performance of the processing unit. In an embodiment, the time-slice is a contiguous period of time of processing unit execution, and the specified processing unit event includes a cache event. The processing unit may interleave processing of multiple different units of work across multiple contiguous time-slices, and during a single time-slice, a single unit of work of the multiple different units of work is processed by the processing unit.

Abstract: A Sort Lists instruction is provided to perform a sort and/or a merge operation. The instruction is an architected machine instruction of an instruction set architecture and is executed by a general-purpose processor of the computing environment. The executing includes sorting a plurality of input lists to obtain one or more sorted output lists, which are output.

Abstract: A guarded storage facility sets up a boundary indicating a range of addresses to be guarded or protected. When a program attempts to access an address in a guarded section defined by the boundary, a guarded storage event occurs. Use of this facility facilitates performance of certain tasks within a computing environment, including storage reclamation.

Abstract: A computing environment facility is provided to extend a hold of a cache line in private (or local) cache exclusively after processing a storage operand request. The facility includes determining whether a storage operand request to a storage location shared by multiple processing units of the computing environment is designated hold. In addition, a determination is made whether a state of the corresponding cache line in private cache used for processing the storage operand request is owned exclusively. Based on determining that the storage operand request is designated hold, and that the state of the corresponding cache line in private cache used for processing the storage operand request is owned exclusively, continuing to hold the corresponding cache line in the private cache exclusively after completing processing of the storage operand request. The continuing to hold may include initiating a counter to facilitate the continuing hold for a desired, set interval.
