+Description: 	The ACPI pm_profile sysfs interface exports the platform
+		power management (and performance) requirement expectations
+		as provided by BIOS. The integer value is directly passed as
+		retrieved from the FADT ACPI table.
+Values:         For possible values see ACPI specification:
+		5.2.9 Fixed ACPI Description Table (FADT)
+		Field: Preferred_PM_Profile
+
+		Currently these values are defined by spec:
+		0 Unspecified
+		1 Desktop
+		2 Mobile
+		3 Workstation
+		4 Enterprise Server
+		5 SOHO Server
+		6 Appliance PC
