1. A method of improving efficiency of a refresh operation on a translation lookaside buffer (TLB) using an enhanced refresh PCI translation (RPCIT) operation to refresh a translation lookaside buffer (TLB), the method comprising: analyzing, by a computer processor, an enhanced RPCIT instruction block indicating a request to perform at least one RPCIT instruction for performing a series of refresh operations to purge at least one translation from the TLB; and purging, by the computer processor, the at least one translation from the TLB in response to executing the at least one RPCIT instruction, wherein the computer processor selectively sets a bit value of a synchronization bypass (SB) control bit included in the enhanced RPCIT instruction block to perform a synchronization bypass operation prior to completing the at least one RPCIT instruction such that the series of refresh operations are continuously executed without interruption until executing a final refresh operation included in the series of refresh operations, wherein the computer processer sets the SB control bit value to a first bit value to bypass the synchronization operation such that the series of refresh operations are continuously executed without interruption, and sets the SB control bit value to a second bit value to invoke the synchronization operation in response to completing the final refresh operation included in the series of refresh operations.
