Abstract
Techniques for coherency management based on coherent hierarchical cache line tracking are disclosed. A plurality of processor cores is accessed. Each processor of the plurality of processor cores includes a local cache. A hierarchical cache is coupled to the plurality of processor cores. The hierarchical cache is shared among the plurality of processor cores. Coherency between the plurality of processor cores and the hierarchical cache is managed by a compute coherency block (CCB). A cache line directory is provided for the CCB. The cache line directory includes a core list field and a cache line present field. A cache line operation is detected. The cache line operation is detected by the CCB. The cache line operation is represented by an entry in the cache line directory. The cache line operation is performed, based on corresponding values of the core list field and the line present field.
