+What: /sys/firmware/acpi/pm_profile
+Date: 03-Nov-2011
+KernelVersion: v3.2
+Contact: linux-acpi@vger.kernel.org
+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
+ 7 Performance Server
+ >7 Reserved
