1 | What: /sys/devices/platform/samsung/performance_level |
2 | Date: January 1, 2010 | |

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