+          This ACPI processor uploads Power Management information to the Xen
+          hypervisor.
+
+          To do that the driver parses the Power Management data and uploads
+          said information to the Xen hypervisor. Then the Xen hypervisor can
+          select the proper Cx and Pxx states. It also registers itslef as the
+          SMM so that other drivers (such as ACPI cpufreq scaling driver) will
+          not load.
