Description/Purpose
Enables Adjanced cache line prefetch
feature in order to effectivelly hide
memory latency and improve application
performance.
Enables or disables Intel Virtualization
Technology (VT-x). Takes affect only
after power cycling.
Enable the power management features.
Allows processor to dynamically
transition speed and voltage states using
Enhanced Intel SpeedStep Technology.
Allows processor to make use of Intel
Turbo Boost technology. When enabled,
it dynamically changes CPU clock speed
depending on demand and current
processor's operating state and limit.
Specifies which mode of power-
performance states is applied.
In HW_ALL mode, processor is
responsible for coordinating P-State
among logical processors dependencies.
In SW_ALL the OS power manager
takes care of P-State coordination
between logical processors and must
initiate the transition on all of those
processors.
In SW_ANY mode, the OS power
manager may initiate the transition on
any of those logical processor.
Enable/Disable CPU C3(ACPI C2) report
to OS.
