36 	Enable code/data prioritization in L3 cache allocations.
43 L2 and L3 CDP are controlled separately.
67 Cache resource(L3/L2)  subdirectory contains the following files

257 	This contains a set of files organized by L3 domain and by

341 On current generation systems there is one L3 cache per socket and L2
343 isn't an architectural requirement. We could have multiple separate L3

395 threads, having 50% bandwidth, each consuming 5GBps' consumes the max L3
399 has capacity, the L3 external bandwidth is fully used. Also note that
424 L3 schemata file details (code and data prioritization disabled)
426 With CDP disabled the L3 schemata format is::
428 	L3:<cache_id0>=<cbm>;<cache_id1>=<cbm>;...
430 L3 schemata file details (CDP enabled via mount option to resctrl)
432 When CDP is enabled L3 control is split into two separate resources
454 Memory b/w domain is L3 cache.
462 Memory bandwidth domain is L3 cache.
597      writing "3" to the pseudo_lock_measure file will trigger the L3 cache
