| Description: Some Samsung laptops have different "performance levels" |
| that are can be modified by a function key, and by this |
| sysfs file. These values don't always make a whole lot |
| of sense, but some users like to modify them to keep |
| their fans quiet at all costs. Reading from this file |
| will show the current performance level. Writing to the |
| file can change this value. |
| Valid options: |
| "silent" |
| "normal" |
| "overclock" |
| Note that not all laptops support all of these options. |
| Specifically, not all support the "overclock" option, |
| and it's still unknown if this value even changes |
| anything, other than making the user feel a bit better. |
