Abstract

Aspects include computing devices, systems, and methods for implementing a cache maintenance or status operation for a component cache of a system cache. A computing device may generate a component cache configuration table, assign at least one component cache indicator of a component cache to a master of the component cache, and map at least one control register to the component cache indicator by a centralized control entity. The computing device may store the component cache indicator such that the component cache indicator is accessible by the master of the component cache for discovering a virtualized view of the system cache and issuing a cache maintenance or status command for the component cache bypassing the centralized control entity. The computing device may receive the cache maintenance or status command by a control register associated with a cache maintenance or status command and the component cache bypassing the centralized control entity.
