1 | What: /sys/devices/platform/samsung/performance_level | ||

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. | ||
