Preboot ACL is a mechanism that allows connecting Thunderbolt devices boot time in more secure way than the legacy Thunderbolt boot support. As with the legacy boot option, this also needs to be enabled from the BIOS before booting is allowed. Difference to the legacy mode is that the userspace software explicitly adds device UUIDs by sending a special message to the ICM firmware. Only the devices listed in the boot ACL are connected automatically during the boot. This works in both "user" and "secure" security levels. We implement this in Linux by exposing a new sysfs attribute (boot_acl) below each Thunderbolt domain. The userspace software can then update the full list as needed.

README
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.
