Processing incoming write-back and replacement messages

On write-back or replacement messages, the directory transitions to state DIRWRB. These accesses call Dir_Cohe in order to make changes to the state of the line. If any pending REQUESTs are waiting on this write-back or replacement message, those are marked as being ready for processing.
