NAME
boltctl - control the thunderbolt device manager
SYNOPSIS
boltctl authorize DEVICE
boltctl config
boltctl domains
boltctl enroll DEVICE
boltctl forget DEVICE
boltctl info DEVICE
boltctl list
boltctl monitor
boltctl power
DESCRIPTION
boltctl is the command line interface to interact with boltd, the system daemon that
manages Thunderbolt 3(TM) devices. It can be used to query the state of devices as well as
manage them.
Devices can be globally identified via their unique identifier (uuid). All commands that
take a DEVICE identifier expect this unique id.
If no command is given, it is equivalent to boltctl list.
OPTIONS
--version
Print version information and exit.
-U | --uuid {full | short | alias | N}
Control how UUIDs are printed. Since they are somewhat sensitive data it is not
advisable to share them publicly in full length. Instead short or alias can and should
be used when sharing the output of boltctl.
full
Print all UUIDs in full length.
short
Truncate all UUIDs so only the first 13 characters are printed.
alias
All UUIDs are replaced by a random string that is derived from the UUID, therefore
the devices can be uniquely identified without revealing the original UUID.
N
If a integer N is specified, all UUIDs are truncated to only show up to N.
COMMANDS
authorize [-F | --first-time] DEVICE
Authorize a currently unauthorized device identified via its unique id (uuid) DEVICE. If a
key is stored in the database it will be used, given the security level of the domain
supports secure device connection. Use boltctl list to find out the uuid of a device.
-F | --first-time
Normally, when attempting to authorize an already authorized device boltctl will do
nothing and return a successful status code. When using this option, the attempt will
fail and result in a negative exit code if the device is already authorized.
config --describe [global|domain|device]
List global, domain, or all (if nothing is specified) properties. The format is 3 columns:
permission, name, description. Permission indicates if the property is only readable or
can also be written.
config KEY [VALUE]
Get or set, if VALUE is specified, a global property.
config <domain|device>.KEY TARGET [VALUE]
Get or set, if VALUE is specified, a domain or device property, where TARGET is the unique
id of the domain or the device.
domains [-v | --verbose]
List all currently active Thunderbolt domains. A Thunderbolt domain represents the
Thunderbolt controller hardware. There will be one domain (and host device) for each
Thunderbolt controller present in the system. The security property shows the security
level of the controller. If iommu support is active (see the boltd man page) it will be
indicated by a +iommu suffix for "secure" or "user" mode, or just plain iommu in case the
security level is "none" (sl0). bootacl shows the used and total slots of the boot access
control list (BootACL) and the content of all non-empty entries. NB: if BootACL is
unsupported it will show 0 for both (0/0). The online property shows if the thunderbolt
controller is currently powered by the firmware. NB: if the controller is currently
offline the BootACL list will reflect what boltd estimates the list will look like once
the controller is back online and local changes have been synchronized to the controller.
This might not be accurate if the list was modified in the meantime, e.g. from a different
installation or OS.
enroll [--policy policy] DEVICE
Authorize and record the device with the unique id DEVICE in the database. If the domain
supports secure connection a new key will be generated and stored in the database
alongside the device name and vendor name. The key, if created, will be used in the future
to securely authorize the device.
--policy {default | auto | manual}
Specify the policy to be used for the newly enrolled device.
default
Use the global default policy of the daemon; this can be changed, but is normally
also auto.
auto
Automatically authorize this device whenever it is connected.
manual
Do not automatically authorize the device; instead require manual authorization
via boltctl authorize.
forget DEVICE
Remove the information about the device with the unique id DEVICE from the database. This
includes the key, if one was previously generated. If you pass --all instead of the DEVICE
all devices are removed instead of just one.
info DEVICE
Display information about the device with the unique id DEVICE.
list [-a | --all]
List and print information about all connected and stored devices.
-a | --all
Normally, the only the device type that will be shown is peripherals. Therefore the
device that represents the host itself will be omitted. Using this option will instead
include all device types in the list.
monitor
Listen for and show changes in connected devices.
power [-t | --timeout seconds] [-q | --query]
Power up the Thunderbolt controller. If the Thunderbolt controller is not in "native
enumeration mode" it can be completely powered down by the host firmware/BIOS. On
supported systems there is an interface to "force" power the thunderbolt controller. If
supported this command will request the daemon to do so. The daemon will keep track of all
client requests and will release the force power override when the last request is
released.
-t | --timeout seconds
Release the force power request after the specified amount of seconds and exit.
-q | --query
Query the current force power status of the daemon.
