ABSTRACT:
A method and apparatus for fencing the execution of commands. A fence command and an executable command are received in succession. The executable command is enqueued in a first queue together with an indication that the executable command succeeded the fence command. A synchronization value is enqueued in a second queue. The executable command is then delayed from being dequeued from the first queue until the synchronization value is advanced to the head of the second queue.
