- See IEEE 1212 for semantic definitions.
- config_rom
- Contents of the Configuration ROM register.
- Binary attribute; an array of host-endian u32.

- Description:
- IEEE 1394 node device attribute.
- Read-only. Mutable during the node device's lifetime.
- See IEEE 1212 for semantic definitions.
- units
- Summary of all units present in an IEEE 1394 node.
- Contains space-separated tuples of specifier_id and
- version of each unit present in the node. Specifier_id
- and version are hexadecimal string representations of
- u24 of the respective unit directory entries.
- Specifier_id and version within each tuple are separated
- by a colon.

- Description:
- IEEE 1394 node device attribute.
- Read-only and immutable.
- Values: 1: The sysfs entry represents a local node (a controller card).
- 0: The sysfs entry represents a remote node.

- Description:
- IEEE 1394 unit device attributes.
- Read-only. Immutable during the unit device's lifetime.
- See IEEE 1212 for semantic definitions.
- modalias
- Same as MODALIAS in the uevent at device creation.
- rom_index
- Offset of the unit directory within the parent device's
- (node device's) Configuration ROM, in quadlets.
- Decimal string representation.

- Description:
- Attributes common to IEEE 1394 node devices and unit devices.
- Read-only. Mutable during the node device's lifetime.
- Immutable during the unit device's lifetime.
- See IEEE 1212 for semantic definitions.
- These attributes are only created if the root directory of an
- IEEE 1394 node or the unit directory of an IEEE 1394 unit
- actually contains according entries.
- hardware_version
- Hexadecimal string representation of an u24.
- hardware_version_name
- Contents of a respective textual descriptor leaf.
- model
- Hexadecimal string representation of an u24.
- model_name
- Contents of a respective textual descriptor leaf.
- specifier_id
- Hexadecimal string representation of an u24.
- Mandatory in unit directories according to IEEE 1212.
- vendor
- Hexadecimal string representation of an u24.
- Mandatory in the root directory according to IEEE 1212.
- vendor_name
- Contents of a respective textual descriptor leaf.
- version
- Hexadecimal string representation of an u24.
- Mandatory in unit directories according to IEEE 1212.

- Description:
- SCSI target port identifier and logical unit identifier of a
- logical unit of an SBP-2 target. The identifiers are specified
- in SAM-2...SAM-4 annex A. They are persistent and world-wide
- unique properties the SBP-2 attached target.
- Read-only attribute, immutable during the target's lifetime.
- Format, as exposed by firewire-sbp2 since 2.6.22, May 2007:
- Colon-separated hexadecimal string representations of
- u64 EUI-64 : u24 directory_ID : u16 LUN
- without 0x prefixes, without whitespace. The former sbp2 driver
- (removed in 2.6.37 after being superseded by firewire-sbp2) used
- a somewhat shorter format which was not as close to SAM.
- Users: udev rules to create /dev/disk/by-id/ symlinks
