58c2ecf20Sopenharmony_ciDescription:	Some Samsung laptops have different "performance levels"
68c2ecf20Sopenharmony_ci		that can be modified by a function key, and by this
78c2ecf20Sopenharmony_ci		sysfs file.  These values don't always make a whole lot
88c2ecf20Sopenharmony_ci		of sense, but some users like to modify them to keep
98c2ecf20Sopenharmony_ci		their fans quiet at all costs.  Reading from this file
108c2ecf20Sopenharmony_ci		will show the current performance level.  Writing to the
118c2ecf20Sopenharmony_ci		file can change this value.
128c2ecf20Sopenharmony_ci
138c2ecf20Sopenharmony_ci			Valid options:
148c2ecf20Sopenharmony_ci				- "silent"
158c2ecf20Sopenharmony_ci				- "normal"
168c2ecf20Sopenharmony_ci				- "overclock"
178c2ecf20Sopenharmony_ci
188c2ecf20Sopenharmony_ci		Note that not all laptops support all of these options.
198c2ecf20Sopenharmony_ci		Specifically, not all support the "overclock" option,
208c2ecf20Sopenharmony_ci		and it's still unknown if this value even changes
218c2ecf20Sopenharmony_ci		anything, other than making the user feel a bit better.
