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.
