+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.
