Reading from these files on a supported 8 processor will return that cache disable index value 9 for that processor and node. Writing to one of these 10 files will cause the specificed cache index to be disabled. 11 12 Currently, only AMD Family 10h Processors support cache index 13 disable, and only for their L3 caches.
