Zusammenfassung:	Methods and apparatuses are disclosed for direct access to cache memory. Embodiments include receiving, by a direct access manager that is coupled to a cache controller for a cache memory, a region scope zero command describing a region scope zero operation to be performed on the cache memory; in response to receiving the region scope zero command, generating a direct memory access region scope zero command, the direct memory access region scope zero command having an operation code and an identification of the physical addresses of the cache memory on which the operation is to be performed; sending the direct memory access region scope zero command to the cache controller for the cache memory; and performing, by the cache controller, the direct memory access region scope zero operation in dependence upon the operation code and the identification of the physical addresses of the cache memory.
