Abstract: De acuerdo con una o más modalidades de la presente invención, un método implementado por computadora incluye recibir, en un control de interfaz segura de un sistema de computadora, una solicitud de acceso para una estructura de datos relacionada con una entidad segura en un dominio seguro del sistema de computadora. El control de interfaz segura puede verificar una dirección de almacenamiento virtual asociada con una ubicación de la estructura de datos. El control de interfaz segura puede solicitar una traducción de direcciones usando un espacio de dirección virtual de una entidad no segura del sistema de computadora con base en la determinación de que la ubicación de la estructura de datos se asocia con la dirección de almacenamiento virtual. El control de interfaz segura puede acceder a la estructura de datos con base en un resultado de la traducción de direcciones.

Abstract: Se ejecuta una instrucción para llevar a cabo una operación de desplazamiento y división. La ejecución incluye desplazar un valor en una dirección especificada una cantidad seleccionada para proporcionar un dividendo, la cantidad seleccionada siendo definida por el usuario. El dividendo se divide por un divisor para obtener un cociente. Al menos un subconjunto del cociente se selecciona como resultado. El resultado será utilizado en el procesamiento dentro del entorno de computación.

Abstract: Vector pack and unpack instructions are described. An instruction to perform a conversion between one decimal format and another decimal format is executed, in which the one decimal format or the other decimal format is a zoned decimal format. The executing includes obtaining a value from at least one register specified using the instruction. At least a portion of the value is converted from the one decimal format to the other decimal format different from the one decimal format to provide a converted result. A result obtained from the converted result is written into a single register specified using the instruction.

Abstract: An indication of a function to be executed is obtained, in which the function is one function of an instruction and configured to perform multiple operations. A determination is made of an operation of the multiple operations to be performed, and a set of function-specific parameters is validated using a set of values and a corresponding set of relationships. The set of values and corresponding set of relationships are based on the operation to be performed. One set of values and corresponding set of relationships are to be used for the operation to be performed, and another set of values and corresponding set of relationships are to be used for another operation of the multiple operations.

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: Saving and restoring machine state between multiple executions of an instruction. A determination is made that processing of an operation of an instruction executing on a processor has been interrupted prior to completion. Based on determining that the processing of the operation has been interrupted, current metadata of the processor is extracted. The metadata is stored in a location associated with the instruction and used to re-execute the instruction to resume forward processing of the instruction from where it was interrupted.

Abstract: A method is provided. A secure interface control in communication with an untrusted entity perform the method. In this regard, the secure interface control implements an initialization instruction to set donated storage as secure. The implementing of the initialization instruction is responsive to an instruction call issued from the untrusted entity.

Abstract: An instruction to perform a sign operation of a plurality of sign operations configured for the instruction. The instruction is executed, and the executing includes selecting at least a portion of an input operand as a result to be placed in a select location. The selecting is based on a control of the instruction, in which the control indicates a user-defined size of the input operand to be selected as the result. A sign of the result is determined based on a plurality of criteria, including a value of the result, obtained based on the control of the instruction, having a first particular relationship or a second particular relationship with respect to a selected value. The result and the sign are stored in the select location to provide a signed output to be used in processing within the computing environment.

Abstract: According to one or more embodiments of the present invention, a computer implemented method includes initiating, by a non-secure entity that is executing on a host server, a secure entity, the non-secure entity prohibited from directly accessing any data of the secure entity. The method further includes injecting, into the secure entity, an interrupt that is generated by the host server. The injecting includes adding, by the non-secure entity, information about the interrupt into a portion of non-secure storage, which is then associated with the secure entity. The injecting further includes injecting, by a secure interface control of the host server, the interrupt into the secure entity.
