Some graphics drivers such as i915 support runtime power management and if there is nothing connected at the moment they will runtime suspend to save power. At least i915 is polling for new connections every 10 seconds if the hardware does support sending PME. To allow i915 and other graphics from detect the just established DisplayPort tunnel allow the DPRX capabilities read to take up to 12 seconds.

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 reStructuredText 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.
