    Abstract: A method, computer program product, and a system where a secure interface control determines functionality of a secure guest based on metadata. The secure interface control ("SC") obtains metadata linked to an image of a secure guest to be started by an owner and managed by the hypervisor, where the metadata comprises control(s) that indicate whether a secure guest generated with the image is permitted to obtain a response to a particular request. The SC intercepts, from the secure guest generated with the image, during runtime, a request. The SC determines, based on the control(s), if the secure guest is permitted to obtain a response to the request. If permitted, the SC commences fulfillment of the request, within the computing system. If not permitted, the SC ignores the request.

    IPC: G06F16/903

    Abstract: An instruction is provided for performing a vector string search. The instruction to be processed is obtained, with the instruction being defined to be a string search instruction to locate occurrence of a substring within a string. The instruction is processed, with the processing including searching the string specified in one operand of the instruction using the substring specified in another operand of the instruction. Based on the searching locating a first full match of the substring within the string, a full match condition indication is returned with position of the first full match in the string, and based on the searching locating only a partial match of the substring at a termination of the string, a partial match condition indication is returned, with the position of the partial match in the string.

    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 at least one 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. The asynchronous core-nest interface (14) comprises an input/output status array (44) with multiple input/output status buffers (24).

    IPC: G06F7/491

    Abstract: An instruction to perform a shift and divide operation is executed. The executing includes shifting a value in a specified direction by a selected amount to provide a dividend, the selected amount being user-defined. The dividend is divided by a divisor to obtain a quotient. At least a subset of the quotient is selected as a result. The result is to be used in processing within the computing environment.

    Abstract: An instruction to perform a multiply and shift operation is executed. The executing includes multiplying a first value and a second value obtained by the instruction to obtain a product. The product is shifted in a specified direction by a user-defined selected amount to provide a result, and the result is placed in a selected location. The result is to be used in processing within the computing environment.
