Embodiments relate to enhancing a refresh PCI translation (RPCIT) instruction to refresh a translation lookaside buffer (TLB). A computer processor determines a request to purge a translation for a single frame of the TLB in response to executing an enhanced RPCIT instruction. The enhanced RPCIT instruction is configured to selectively perform one of a single-frame TLB refresh operation or a range-bounded TLB refresh operation. The computer processor determines an absolute storage frame based on a translation of a PCI virtual address in response to the request to purge a translation for a single frame of the TLB. The computer processer further performs the single-frame TLB refresh operation to purge the translation for the single frame.
