A load when reservation lost instruction for performing cacheline polling is disclosed. Initially, a first process requests an action to be performed by a second process. The request is made via a store operation to a cacheable memory location. The first process then reads the cacheable memory location via a conditional load operation to determine whether or not the requested action has been completed by the second process, and the first process sets a reservation at the cacheable memory location if the requested action has not been completed by the second process. The conditional load operation of the first process is stalled until the reservation at the cacheable memory location has been lost. After the requested action has been completed, the reservation in the cacheable memory location is reset by the second process.
