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.
