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.
