Is: drivers/cpufreq/cpufreq-xen.c Was:Re: [PATCH 2 of 2] linux-xencommons: Load processor-passthru
...at you are suggesting is that to write a driver in drivers/cpufreq/
that gets either started before the other ones (if built-in) or if as
a module gets
loaded from xencommons. That driver would then make the call
to acpi_processor_preregister_performance(),
acpi_processor_register_performance() and acpi_processor_notify_smm().
It would function as a cpufreq-scaling driver but
in reality all calls to it from cpufreq gov-* drivers would end up with nop.
Dave, would you be Ok with a driver like that in your tree?

[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
