Currently, kernel shows the below values "persistence_domain":"cpu_cache" "persistence_domain":"memory_controller" "persistence_domain":"unknown" "cpu_cache" indicates no extra instructions is needed to ensure the persistence of data in the pmem media on power failure. "memory_controller" indicates cpu cache flush instructions are required to flush the data. Platform provides mechanisms to automatically flush outstanding write data from memory controler to pmem on system power loss. Based on the above use memory_controller for non volatile regions on ppc64.
