Abstract: A system for managing cache utilization includes a processor core, a lower-level cache, and a higher-level cache. In response to activating the higher-level cache, the system counts lower-level cache victims evicted from the lower-level cache.

When the count of the lower-level cache victims is greater than the threshold number, the system writes each lower-level cache victim to the higher-level cache. In this manner, if the higher-level cache is deactivated before the threshold number of lower-level cache victims is reached, the higher-level cache is empty and thus may be deactivated without flushing.
