    摘要： An enhanced dynamic address translation facility product is created such that, in one embodiment, a virtual address to be translated and an initial origin address of a translation table of the hierarchy of translation tables are obtained. Dynamic address translation of the virtual address proceeds. In response to a translation interruption having occurred during dynamic address translation, bits are stored in a translation exception qualifier (TXQ) field to indicate that the exception was either a host DAT exception having occurred while running a host program or a host DAT exception having occurred while running a guest program. The TXQ is further capable of indicating that the exception was associated with a host virtual address derived from a guest page frame real address or a guest segment frame absolute address. The TXQ is further capable of indicating that a larger or smaller host frame size is preferred to back a guest frame.

    摘要： An enhanced dynamic address translation facility is provided. In one embodiment, a virtual address to be translated and an initial origin address of a translation table of the hierarchy of translation tables are obtained. An index portion of the virtual address is used to reference an entry in the translation table. If a format control field contained in the translation table entry is enabled, the table entry contains a frame address of a large block of data of at least 1M byte in size. The frame address is then combined with an offset portion of the virtual address to form the translated address of a small 4K byte block of data in main storage or memory.

    摘要： Aspects include a system, method and computer program product for providing a shared memory translation facility. The method includes receiving a request for access to a memory address from a requestor at a configuration, the receiving at a shared memory translation mechanism. It is determined whether the memory address refers to a shared memory object (SMO), the SMO accessible by a plurality of configurations managed in different zones of memory. Based on determining that the memory address refers to the SMO, it is determined whether the configuration has access to the SMO. Based on determining that the configuration has access to the SMO, the requestor is provided a system absolute address for the SMO and access to the SMO. In this manner direct interchange of data between the configuration and the plurality of configurations is allowed.

    摘要： What is provided is an enhanced dynamic address translation facility. In one embodiment, a virtual address to be translated is first obtained and an initial origin address of a translation table of the hierarchy of translation tables is obtained. Based on the obtained initial origin, a segment table entry is obtained. The segment table entry is configured to contain a format control and access validity fields. If the format control and access validity fields are enabled, the segment table entry further contains an access control field, a fetch protection field, and a segment-frame absolute address. Store operations are permitted only if the access control field matches a program access key provided by any one of a Program Status Word or an operand of a program instruction being emulated. Fetch operations are permitted if the program access key associated with the virtual address is equal to the segment access control field or the fetch protection field is not enabled.

    摘要翻译： 提供的是增强的动态地址转换设施。 在一个实施例中，首先获得要被翻译的虚拟地址，并且获得翻译表层级的翻译表的初始起始地址。 基于获得的初始来源，获得段表条目。 段表项被配置为包含格式控制和访问有效性字段。 如果启用格式控制和访问有效性字段，则段表条目还包含访问控制字段，提取保护字段和段帧绝对地址。 仅当访问控制字段与程序状态字或被仿真的程序指令的操作数提供的程序访问键匹配时才允许存储操作。 如果与虚拟地址相关联的程序访问密钥等于段访问控制字段或者没有启用读取保护字段，则允许获取操作。
