    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 fetching of storage keys 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 addresses, which indicates whether the fetching can continue. If fetching can continue, the restriction is ignored.

    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.

    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: A system, method and computer program product for providing a programmable quiesce filtering register. The method includes receiving a quiesce interruption request at the processor. The processor is executing in a mode. A filtering zone associated with the mode is identified. It is determined if the quiesce interruption request can be filtered by the processor. The determining is responsive to the filtering zone and to contents of a programmable filtering register for indicating exceptions to filtering performed by the receiving processor. The quiesce interruption request is filtered in response to determining that the request can be filtered.
