At the moment, "schemata" file contains information about cache portion bitmap (CPBM), and memory bandwidth allocation (MBA) in the following format. MB:0=0100 L3:0=ffff Lets' update the "schemata" file to accommodate information about priority partition control that indicates downstream priority value. For instance: L3:0=ffff,f CPBM is separated from downstream priority value using delimiter ",".
