When user presses Fn-F5, the driver automatically changes throttle thermal policy (or fan boost mode, depending on laptop model). It would be convenient for userspace software to be able to poll on corresponding sysfs variable. For example, to show a notification about mode change. Note that there is currently no way to handle Fn-F5 from userspace directly, driver does not pass it.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
