AMD PowerNow! in Xen
This patch set moves support for AMD's PowerNow! technology from
dom0 into the hypervisor, now that there is support for
transferring ACPI data to the hypervisor. It will only work for
AMD processors that support the architectural P-state driver,
such as 3rd generation Opterons, Phenoms, and Turion Ultras.
This patch creates the Architectural P-state driver inside
of the Xen hypervisor and hooks it into the Xen code. It
has been tested at AMD with a variety of para- and fully-
virtualized guests for a week without regressions.
