摘要： A system, method and computer program product for translations in a computer system. The system includes a general purpose register containing a base address of an address translation table. The system also includes a millicode accessible special displacement register configured to receive a plurality of elements to be translated. The system further includes a multiplexer for selecting a particular one of the plurality of elements from the millicode accessible special displacement register and for generating a displacement or offset value. The system further includes an address generator for creating a combined address containing the base address from the general purpose register and the generated displacement or offset value.

摘要： A command is issued to reset one or more pending interrupt indicators and arbitrate for ownership of the interrupt. Responsive to a processor receiving the command, a check is made of a selected pending interrupt indicator. If the selected pending interrupt indicator is not set, another pending interrupt indicator is checked, instead of providing a negative response and reissuing the command. In this way, one dequeue command can replace multiple dequeue commands and the overhead of leaving and re-entering the interrupt handler is reduced. A negative response is reserved for those situations in which there are no pending interrupt indicators to be reset.
摘要翻译：发出命令以重置一个或多个待处理的中断指示符并仲裁中断的所有权。响应于接收到该命令的处理器，检查所选待处理的中断指示符。如果未设置所选待处理的中断指示符，则会检查另一个未决中断指示符，而不是提供否定响应并重新发出命令。以这种方式，一个出队命令可以取代多个出队命令，减少了离开和重新进入中断处理程序的开销。对于没有待复位的待处理中断指示符的情况，保留一个否定的响应。

摘要： Input/output (I/O) operation requests from pageable storage mode guests are interpreted without host intervention. In a pageable mode virtual environment, requests issued by pageable storage mode guests are processed by one or more processors of the environment absent intervention from one or more hosts of the environment. Processing of the requests includes manipulating, by at least one processor on behalf of the guests, buffer state information stored in host storage. The manipulating is performed via instructions initiated by the guests and processed by one or more of the processors.

摘要： Input/output (I/O) operation requests from pageable storage mode guests are interpreted without host intervention. In a pageable mode virtual environment, requests issued by pageable storage mode guests are processed by one or more processors of the environment absent intervention from one or more hosts of the environment. Processing of the requests includes manipulating, by at least one processor on behalf of the guests, buffer state information stored in host storage. The manipulating is performed via instructions initiated by the guests and processed by one or more of the processors.

摘要： An apparatus is disclosed for operating a symmetric cipher engine (SCE) in cipher-block chaining (CBC) mode, the apparatus comprises a crypto operation hardware comprising said SCE, an XOR stage, an apparatus for storing a chaining value comprising a state register of said SCE, an input latch supplying said crypto operation hardware with data, and an output latch. The data may be reordered for decipher operations. Furthermore, a method is disclosed for operating a SCE in CBC mode, wherein the method involves a crypto operation hardware that comprises said SCE and an XOR stage supplied with data. The method may also comprise using a state register of said SCE to apply a chaining value. Said method may comprise reordering data supplied to said crypto operation hardware for decipher operations.
