[RFC PATCH] Exporting ACPI Pxx/Cxx states to other kernel subsystems (v1).
Hello,
The following patches are a solution to a problem we have encountered
when using the Xen hypervisor:
- Need Pxx/Cxx states to save on power consumption when using Xen (we
do want those datacenters to consume less power!),
- Also need to figure out the Turbo mode so that the scheduler can properly
boost a core for CPU bound guests.
In essence the Xen hypervisor requires that
