ACPI 6.4 introduced a new _OSC capability used to negotiate whether the OS is supposed to use Software (native) or Firmware based Connection Manager. If the native support is granted then there are set of bits that enable/disable different tunnel types that the Software Connection Manager is allowed to tunnel. This adds support for this new USB4 _OSC accordingly. When PCIe tunneling is disabled then the driver switches security level to be "nopcie" following the security level 5 used in Firmware based Connection Manager.

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.
