Description: Reading this file tells if the AMD Platform Management(PMF)
|
||||
Cool n Quiet Framework(CnQF) feature is enabled or not.
|
||||
|
||||
This feature is not enabled by default and gets only turned on
|
||||
if OEM BIOS passes a "flag" to PMF ACPI function (index 11 or 12)
|
||||
or in case the user writes "on".
|
||||
|
||||
To turn off CnQF user can write "off" to the sysfs node.
|
||||
Note: Systems that support auto mode will not have this sysfs file
|
||||
available.
