Abstract

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.
