摘要： Permits one program in one address space to obtain access to data in another address space or to call a program in another address space without invoking a supervisor, with authorization to use a storage protect key other than that specifically assigned to the program by a supervisor when in a new semi-privileged state. Programs executing in a particular address space have supervisor assigned storage protect key masks permitting the program, when authorized, to utilize a storage protect key other than the one specifically assigned by the supervisor. A second address space can be designated by a program, and when authorized, can cause transfer of data in main memory from one physical location to another associated with the different address space, and two different storage protect keys can be utilized. A calling program can provide addressability to data in its address space by combining storage protect key masks from the calling program with a key mask of a called program to permit access to data by the called program. Entering the called program causes the saving and changing of a problem/supervisor control bit and instruction address.
摘要翻译：允许一个地址空间中的一个程序获取对另一个地址空间中的数据的访问，或者调用另一个地址空间中的程序，而不调用主管，授权使用存储保护密钥，而不是由主管专门分配给程序在一个新的半特权状态。在特定地址空间中执行的程序具有管理员分配的存储保护密钥掩码，允许程序在授权时利用除了由主管专门分配的存储保护密钥之外的存储保护密钥。第二地址空间可以由程序指定，当被授权时，可能导致主存储器中的数据从一个物理位置传输到另一个与不同地址空间相关联的地址空间，并且可以利用两个不同的存储保护密钥。调用程序可以通过将调用程序的存储保护密钥掩码与被调用程序的密钥掩码相结合来提供其地址空间中的数据的可寻址性，以允许被调用程序访问数据。进入被叫程序导致保存和更改问题/管理员控制位和指令地址。

摘要： One program in one address space is permitted to obtain access to data in another address space or to call a program in another address space without invoking a supervisor. Each of a plurality of address spaces assigned an Address Space Number (ASN) has an associated set of address translation tables. A second address space can be designated by a program, and when authorized, can cause transfer of data in main memory from one physical location to another associated with the different address space. A program changeable space selection control bit controls use of two different sets of address translation tables associated with two different address spaces. Without invoking a supervisor, a particular program in an assigned address space can call a program in another address space or obtain addressability to data in another address space having an associated set of address translation tables.
摘要翻译：一个地址空间中的一个程序被允许访问另一个地址空间中的数据，或者在另一个地址空间中调用程序，而不调用主管。分配了地址空间编号（ASN）的多个地址空间中的每一个具有一组相关的地址转换表。第二个地址空间可以由程序指定，当被授权时，可能导致主存储器中的数据从一个物理位置传输到另一个与不同地址空间相关联的地址空间。程序可变空间选择控制位控制与两个不同地址空间相关联的两组不同地址转换表的使用。在不调用主管的情况下，分配的地址空间中的特定程序可以调用另一地址空间中的程序，或者获得具有相关联的地址转换表集合的另一地址空间中的数据的可寻址性。

摘要： Permits one program in one address space to obtain access to data in another address space without invoking a supervisor. Each of a plurality of address spaces assigned an Address Space Number (ASN) has an associated set of address translation tables. Addressability to a second address space may be specified by a program if authorized in accordance with the entry of an authority table associated with the second address space, the entry being designated by an authorization index associated with the program.

摘要： The embodiments relate to special controls in a processor which eliminate synonym entries in a translation lookaside buffer (DLAT) for a system which has DLAT entries that can concurrently translate virtual addresses in multiple address spaces into real main storage addresses. The controls provide a common space bit in any segment table entry (STE) or alternatively in any page table entry (PTE) in any private address space to indicate whether the segment or page, respectively, contains programs and data private to the address space or shared by all address spaces. Each DLAT entry contains a common/private storage indictor which is set to the state of the common space bit in the STE or PTE used in an address translation loaded into the DLAT entry. When the entry is read, the private/common storage indicator controls whether the DLAT can only be used by the address space identified in the DLAT, or by all address spaces.
