+Processor boosting control
+
+        - information for users -
+
+Quick guide for the impatient:
+--------------------
+/sys/devices/system/cpu/cpufreq/boost
+controls the boost setting for the whole system. You can read and write
+that file with either "0" (boosting disabled) or "1" (boosting allowed).
+Reading or writing 1 does not mean that the system is boosting at this
+very moment, but only that the CPU _may_ raise the frequency at it's
+discretion.
+--------------------
+
+Introduction
+-------------
+Some CPUs support a functionality to raise the operating frequency of
+some cores in a multi-core package if certain conditions apply, mostly
+if the whole chip is not fully utilized and below it's intended thermal
+budget. This is done without operating system control by a combination
+of hardware and firmware.
+On Intel CPUs this is called "Turbo Boost", AMD calls it "Turbo-Core",
+in technical documentation "Core performance boost". In Linux we use
+the term "boost" for convenience.
+
+Rationale for disable switch
+----------------------------
+
+Though the idea is to just give better performance without any user
+intervention, sometimes the need arises to disable this functionality.
+Most systems offer a switch in the (BIOS) firmware to disable the
+functionality at all, but a more fine-grained and dynamic control would
+be desirable:
+1. While running benchmarks, reproducible results are important. Since
+   the boosting functionality depends on the load of the whole package,
+   single thread performance can vary. By explicitly disabling the boost
+   functionality at least for the benchmark's run-time the system will run
+   at a fixed frequency and results are reproducible again.
+2. To examine the impact of the boosting functionality it is helpful
+   to do tests with and without boosting.
+3. Boosting means overclocking the processor, though under controlled
+   conditions. By raising the frequency and the voltage the processor
+   will consume more power than without the boosting, which may be
+   undesirable for instance for mobile users. Disabling boosting may
+   save power here, though this depends on the workload.
+
+
+User controlled switch
+----------------------
+
+To allow the user to toggle the boosting functionality, the acpi-cpufreq
+driver exports a sysfs knob to disable it. There is a file:
+/sys/devices/system/cpu/cpufreq/boost
+which can either read "0" (boosting disabled) or "1" (boosting enabled).
+Reading the file is always supported, even if the processor does not
+support boosting. In this case the file will be read-only and always
+reads as "0". Explicitly changing the permissions and writing to that
+file anyway will return EINVAL.
+
+On supported CPUs one can write either a "0" or a "1" into this file.
+This will either disable the boost functionality on all cores in the
+whole system (0) or will allow the hardware to boost at will (1).
+
+Writing a "1" does not explicitly boost the system, but just allows the
+CPU (and the firmware) to boost at their discretion. Some implementations
+take external factors like the chip's temperature into account, so
+boosting once does not necessarily mean that it will occur every time
+even using the exact same software setup.
+
+
+AMD legacy cpb switch
+---------------------
+The AMD powernow-k8 driver used to support a very similar switch to
+disable or enable the "Core Performance Boost" feature of some AMD CPUs.
+This switch was instantiated in each CPU's cpufreq directory
+(/sys/devices/system/cpu[0-9]*/cpufreq) and was called "cpb".
+Though the per CPU existence hints at a more fine grained control, the
+actual implementation only supported a system-global switch semantics,
+which was simply reflected into each CPU's file. Writing a 0 or 1 into it
+would pull the other CPUs to the same state.
+For compatibility reasons this file and its behavior is still supported
+on AMD CPUs, though it is now protected by a config switch
+(X86_ACPI_CPUFREQ_CPB). On Intel CPUs this file will never be created,
+even with the config option set.
+This functionality is considered legacy and will be removed in some future
+kernel version.
+
+More fine grained boosting control
+----------------------------------
+
+Technically it is possible to switch the boosting functionality at least
+on a per package basis, for some CPUs even per core. Currently the driver
+does not support it, but this may be implemented in the future.
