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.
