- What: /sys/devices/platform/samsung/performance_level
- Date: January 1, 2010
- KernelVersion: 2.6.33
- Contact: Greg Kroah-Hartman <gregkh@suse.de>
- 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.
