| 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. |
