A method for determining an inclusion policy includes determining a ratio of a capacity of a large cache to a capacity of a core cache in a cache subsystem of a processor and selecting an inclusive policy as the inclusion policy for the cache subsystem in response to the cache ratio exceeding an inclusion threshold. The method may further include selecting a non-inclusive policy in response to the cache ratio not exceeding the inclusion threshold and, responsive to a cache transaction resulting in a cache miss, performing an inclusion operation that invokes the inclusion policy.
