5 ``intel_pstate`` CPU Performance Scaling Driver
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
