598 Frequency Boost Support
610 For Intel processors it is referred to as "Turbo Boost", AMD calls it
611 "Turbo-Core" or (in technical documentation) "Core Performance Boost" and so on.
613 term "frequency boost" is used here for brevity to refer to all of those
616 The frequency boost mechanism may be either hardware-based or software-based.
623 The ``boost`` File in ``sysfs``
627 the "boost" setting for the whole system.  It is not present if the underlying
628 scaling driver does not support the frequency boost mechanism (or supports it,
632 If the value in this file is 1, the frequency boost mechanism is enabled.  This
637 permission to use the frequency boost mechanism (which still may never be used
640 If the value in this file is 0, the frequency boost mechanism is disabled and
645 Rationale for Boost Control Knob
648 The frequency boost mechanism is generally intended to help to achieve optimum

685 the global ``boost`` one.  It is used for disabling/enabling the "Core
686 Performance Boost" feature of some AMD processors.
698 ``boost`` knob is present regardless.  Thus it is always possible use the
699 ``boost`` knob instead of the ``cpb`` one which is highly recommended, as that
