What: /sys/devices/platform/*/cnqf_enable
Date: September 2022
Contact: Shyam Sundar S K <Shyam-sundar.S-k@amd.com>
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.
