There''re basically two methods to enter a given C-state: legacy (hlt + I/O read), and native(using mwait). MWAIT is always preferred when both underlying CPU and OS support, which is a more efficient way to conduct C-state transition. Xen PM relies on Dom0 to parse ACPI Cx/Px information, which involves one step to notify BIOS about a set of capabilities supported by OSPM. One capability
