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
|

for formatting information and other details on the
|
|
cache index disable.
