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