摘要： A technique is provided for monitoring a value without repeated storage access. A processing circuit processes an instruction of a program that specifies a memory address of a memory location to be monitored. The processing circuit configures a monitor station for monitoring the memory location. The memory location includes a state descriptor for the program. The processing circuit receives a cross-invalidate request from a memory controller. The cross-invalidate request indicates to the monitor station that content of the memory location has been changed by another processing circuit.

摘要： Storing translation lookaside buffer (TLB) entries are in a TLB1 at the processor. The TLB1 includes entries associated with main storage accesses of programs executing in a guest mode in a current zone and entries associated with main storage accesses of firmware executing in a host mode. A quiesce interruption request is received at the processor that includes a requesting zone indicator. The processor is either executing in the host mode and has no zone or in the guest mode with the current zone. The requesting zone indicator and the contents of a programmable filtering register that indicates exceptions to filtering performed by the processor is used to determine if filtering should be performed. The quiesce interruption request may be filtered based on the requesting zone indicator even after the mode switches from the guest mode to the host mode.

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： 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.
