USB4 inter-domain spec mandates that the compatible hosts expose a new property "maxhopid" that tells the connection manager on the other side what is the maximum supported input HopID over the connection. Since this is depend on the lane adapter the cable is connected it needs to be filled in dynamically. For this reason we take a copy of the global properties and fill then for each XDomain connection upon first connect, and then keep updating it if the generation changes as services are being added/removed. We also take advantage of this copy to fill in the hostname. We also expose this maxhopid as an attribute under each XDomain device. While there drop kernel-doc entry for property_lock which seems to be left there when the structure was originally introduced. Signed-off-by: Mika Westerberg <mika.westerberg@linux.intel.com>
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.
