48 CPU Performance Scaling in Linux
51 The Linux kernel supports CPU performance scaling by means of the ``CPUFreq``
52 (CPU Frequency scaling) subsystem that consists of three layers of code: the
53 core, scaling governors and scaling drivers.
56 interfaces for all platforms that support CPU performance scaling. It defines
59 Scaling governors implement algorithms to estimate the required CPU capacity.

17 :doc:`CPU performance scaling subsystem <cpufreq>` in the Linux kernel
18 (``CPUFreq``). It is a scaling driver for the Sandy Bridge and later
50 ``sysfs`` which allows another ``CPUFreq`` scaling driver to be loaded and

73 In this mode the driver bypasses the scaling governors layer of ``CPUFreq`` and
74 provides its own scaling algorithms for P-state selection. Those algorithms
75 can be applied to ``CPUFreq`` policies in the same way as generic scaling
