Abstract
A livelock preventative measure is provided for agents in a multi-processor computing system. Livelock may occur when multiple agents each trade ownership of data in an attempt to modify it. When livelock occurs, a first agent posts a bus transaction for a data and, if a second agent posts a bus transaction for the same data, the first agent may stall the bus transaction of the second agent until the first agent has completed its operation on the data.
