| |
Resource control group's "schemata" file represents the cache portion bit map (XXXX), parsed from buffer with "L3:0=XXXX" format. Now, with the introduction of priority control, "schemata" file format has changed to "L3:0=XXXX,X", where cpbm (XXXX) is split from priority mask(X) using using delimiter ",".
With this change, CPBM is properly fetched from schemata file when priority partition support is present.
