[RFC] pvops domain0 Cx/Px info parser patch
Hi, Jeremy
Since now the pv_ops domain0 is approaching, we are considering to port the dom0 power management related code, or more specifically, the Cx/Px ACPI info parsing code, to pv_ops domain0 tree, so that people can utilize Xen power management capability (Cx/PX) under pv_ops domain0.
