515 L3 schemata file details (code and data prioritization disabled)
517 With CDP disabled the L3 schemata format is::
521 L3 schemata file details (CDP enabled via mount option to resctrl)
529 L2 schemata file details
531 CDP is supported at L2 using the 'cdpl2' mount option. The schemata

702    bits within the schemata should be "unused" according to the "bit_usage"
