Wake on WLAN(wowlan) is a feature which allows devices to be woken up from suspend state through wlan events. When user enables wowlan feature and then let the device enter suspend state, wowlan firmware will be loaded by the driver and periodically monitors wifi packets. Power consumption of wifi chip will be reduced in this state. If wowlan firmware detects that specific wlan event happens, it will issue wakeup signal to trigger resume process. Driver will load normal firmware and let wifi chip return to the original state. Currently supported wlan events include receiving magic packet, rekey packet and deauth packet, and disconnecting from AP.

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.
