49 CPU Performance Scaling in Linux
52 The Linux kernel supports CPU performance scaling by means of the ``CPUFreq``
53 (CPU Frequency scaling) subsystem that consists of three layers of code: the
54 core, scaling governors and scaling drivers.
57 interfaces for all platforms that support CPU performance scaling. It defines
60 Scaling governors implement algorithms to estimate the required CPU capacity.
61 As a rule, each governor implements one, possibly parametrized, scaling

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
69 In this mode the driver bypasses the scaling governors layer of ``CPUFreq`` and
70 provides its own scaling algorithms for P-state selection. Those algorithms
71 can be applied to ``CPUFreq`` policies in the same way as generic scaling
76 They are not generic scaling governors, but their names are the same as the
173 implemented by the generic ``schedutil`` scaling governor except that the
