ABSTRACT:
A method and apparatus for efficiently posting entries to a queue within the data processing system. Entries are posted by first processor with the entries being handled by second processor in the data processing system. The interrupt state associated with the queue is checked by the first processor. If the interrupt state is clear, then the entry is posted to the queue. This interrupt state is cleared only when all entries have been cleared from the queue by the second processor. In this manner, an efficient posting of entries to the queue may be accomplished.
