Abstract
A method and apparatus are provided for implementing locking of non-data page operations in a memory system. In the method for implementing locking of non-data page operations of the invention, checking for a look aside buffer invalidate request is performed. Responsive to identifying a look aside buffer invalidate request, a real address is locked for the look aside buffer invalidate request. Then checking for a non-data page operation is performed. Responsive to identifying a non-data page operation, checking for the non-data page operation to complete is performed. Responsive to identifying the completed non-data page operation, the real address is unlocked for the look aside buffer invalidate request. Only a lock is placed on the page for a non-data page operation. A look aside buffer invalidate sequence is not performed for the non-data page operation.
