Abstract
An aspect includes a method for operating on translation look-aside buffers (TLBs) in a multiprocessor environment including a plurality of logical partitions as zones. The method includes concurrently receiving a first quiesce request from a first processor of a first zone to quiesce processors of a first set of zones including the first zone and receiving a second quiesce request from a second processor of a second zone to quiesce processors of a second set of zones including the second zone. The second set of zones consists of separate zones from the first set of zones. Based on receiving the first quiesce request, only processors of the first set of zones are quiesced. Based on the processors of the first set of zones being quiesced, a first operation is performed on the TLBs. Based on the first operation being performed, the processors of the first set of zones are un-quiesced.
