    摘要: Selected units of storage, such as segments of storage or regions of storage, are invalidated. The invalidation is facilitated by the setting of invalidation indicators located in data structure entries corresponding to the units of storage to be invalidated. Additionally, buffer entries associated with the invalidated units of storage or other chosen units of storage are cleared. An instruction is provided to perform the invalidation and/or clearing. Moreover, buffer entries associated with a particular address space are cleared, without any invalidation. This is also performed by the instruction. The instruction can be implemented in software, hardware, firmware or some combination thereof, or it can be emulated.

    摘要: Processing restrictions of a computing environment are filtered and blocked, in certain circumstances, such that processing continues despite the restrictions. One restriction includes an indication that address translation is prohibited, in response to a buffer miss. When a processing unit of the computing environment is met with this restriction, it performs a comparison of page indices, which indicates whether the address translation can continue. If address translation can continue, the restriction is ignored. The processing unit includes a processor or a pageable entity, as examples.

    摘要: Processing within a computing environment is facilitated by filtering requests of the computing environment. A processing unit that receives a request determines whether it is to perform the request. This determination is made by, for instance, comparing an identifier of the request with an identifier of the processing unit making the determination. If there is a mismatch, then the request is blocked. Other processing within the computing environment is also facilitated by selectively using buffer entries. The selection criteria is based, for instance, on identifier information.
