Abstract
A method for cache coherency management in multi-level cache systems includes, for occurrence of a conflict eviction from a set of a cache at a first level from the multi-level coherent system, selecting a victim line from the set of the cache for eviction. For the victim line being dirty and a second level from the multi-level coherent system having a copy of the victim line, the method includes writing data to a third level from the multi-level coherent system using a cache maintenance operation, and silently dropping the victim line without notification to the third level. The second level is a level directly lower than the first level, and the third level is a level directly higher than the first level.
