Abstract
A method includes monitoring, at a cache coherence directory, states of cachelines stored in a cache hierarchy of a data processing system using a plurality of entries of the cache coherence directory. Each entry of the cache coherence directory is associated with a corresponding cache page of a plurality of cache pages, and each cache page representing a corresponding set of contiguous cachelines. The method further includes selectively evicting cachelines from a first cache of the cache hierarchy based on cacheline utilization densities of cache pages represented by the corresponding entries of the plurality of entries of the cache coherence directory.
