| Description: These files exist in every cpu's cache index directories. |
| There are currently 2 cache_disable_# files in each |
| directory. Reading from these files on a supported |
| processor will return that cache disable index value |
| for that processor and node. Writing to one of these |
| files will cause the specificed cache index to be disabled. |
| |
| Currently, only AMD Family 10h Processors support cache index |
| disable, and only for their L3 caches. See the BIOS and |
| Kernel Developer's Guide at |
| http://www.amd.com/us-en/assets/content_type/white_papers_and_tech_docs/31116-Public-GH-BKDG_3.20_2-4-09.pdf |
| for formatting information and other details on the |
| cache index disable. |
