Multiprocessor synchronization using region locks |
摘要 |
Disclosed is a method of synchronizing a plurality of processors accesses to at least one shared resource. One of a plurality of processors requests an exclusive region lock for a shared resource using a logical block address (LBA) of a dummy target. The LBA is defined in a region map that associates LBAs to shared resources. The exclusive region lock request is inserted as a node in a region lock tree of the dummy target. Access to the shared resource is granted based on a determination whether there is an existing region lock in the region lock tree that is overlaps with the new exclusive region lock request. |
