Abstract
Storing translation lookaside buffer (TLB) entries are in a TLBat the processor. The TLBincludes 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.
