Abstract

Examples of techniques for software translation prefetch instructions are described herein. An aspect includes, based on encountering a translation prefetch instruction in software that is being executed by a processor, determining whether an address translation corresponding to the translation prefetch instruction is located in a translation lookaside buffer (TLB) of the processor. Another aspect includes, based on determining that the address translation is not located in the TLB, issuing an address translation request corresponding to the translation prefetch instruction. Another aspect includes storing an address translation corresponding to the address translation request in the TLB.
