++``boost``
++The `boost` sysfs attribute provides control over the CPU core
++performance boost, allowing users to manage the maximum frequency limitation
++of the CPU. This attribute can be used to enable or disable the boost feature
++on individual CPUs.
++
++When the boost feature is enabled, the CPU can dynamically increase its frequency
++beyond the base frequency, providing enhanced performance for demanding workloads.
++On the other hand, disabling the boost feature restricts the CPU to operate at the
++base frequency, which may be desirable in certain scenarios to prioritize power
++efficiency or manage temperature.
++
++To manipulate the `boost` attribute, users can write a value of `0` to disable the
++boost or `1` to enable it, for the respective CPU using the sysfs path
++`/sys/devices/system/cpu/cpuX/cpufreq/boost`, where `X` represents the CPU number.
++
++It is important to note that modifying the global variable
++`/sys/devices/system/cpu/amd_pstate/cpb_boost` will override the individual CPU
++settings.
++
++
+ Other performance and frequency values can be read back from
+ ``/sys/devices/system/cpu/cpuX/acpi_cppc/``, see :ref:`cppc_sysfs`.

- quirked
-
-Adjusts the report descriptor for N-Key devices to
-make the output count 0x01 which completely avoids
-the need for a block of filtering.
