Thunderbolt fabric consists of one or more switches. This fabric is called domain and it is controlled by an entity called connection manager. The connection manager can be either internal (driven by a firmware running on the host controller) or external (software driver). This driver currently implements support for the latter. In order to manage switches and their properties more easily we model this domain structure as a Linux bus. Each host controller adds a domain device to this bus, and these devices are named as domainN where N stands for index or id of the current domain. We then abstract connection manager specific operations into a new structure tb_cm_ops and convert the existing tb.c to fill those accordingly. This makes it easier to add support for the internal connection manager in subsequent patches.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
