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.
