VirtualLink standard extends the DisplayPort Alt Mode by utilizing also the USB 2 pins on the USB Type-C connector. It uses the same messages as DisplayPort, but not the DP SVID. At the time of writing, USB IF has not assigned a Standard ID (SID) for VirtualLink, so the manufacturers of VirtualLink adapters use their Vendor IDs as the SVID. Since the SVID specific communication is exactly the same as with DisplayPort alternate mode, there is no need to implement separate driver for VirtualLink. We'll handle the current VirtualLink adapters with probe drivers, and once there is SVID assigned for it, we add it to the displayport alt mode driver. To support probing drivers, exporting the probe and remove functions, and also changing the DP_HEADER helper macro to use the SVID of the alternate mode device instead of the DisplayPort alt mode SVID.

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.
