Release Notes: Kernel Drivers

See Release Notes - Libraries for changelogs of some IEEE 1394 userspace libraries.

Release Status

The latest stable releases of Linux IEEE 1394 drivers are those in the latest released Linux 3.x kernels.

The drivers in Linux 2.4 were considered stable too but have not been updated anymore for a long time. Therefore they lack many features and compatibility updates which went into recent Linux 2.6.x and 3.x releases.

The following release notes only summarize more notable changes. A complete list of IEEE 1394 related changes is available via kernel.org git:

Linux 4.5

tentative release notes as per v4.5-rc7

snd-dice
  • Improved handling of DICE II firmware bootstrapping during device start-up.
  • Avoid time-out when PCM streaming is started.

  • Add support for TASCAM FW-1804.
snd-scs1x
  • The functionality of this driver was moved to the snd-oxfw driver, and the now obsolete snd-scs1x module has been removed.


Linux 4.4

10 January 2016

firewire-ohci
  • Work around JMicron JMB38x initialization quirk. Affected isochronous transmission, e.g. audio via FFADO or ALSA. Also fixed in v4.3.3, v4.2.8, v4.1.15, v3.14.59, v3.12.52, v3.10.95, 3.2.74.
snd-bebob
  • Fix device identifier of Mackie Onyx 1220/1620/1640 FireWire I/O card.
snd-dice
  • Fix device identifier of Mackie Onyx Blackbird and Onyx-i series.
snd-firewire-digi00x
  • New driver for Digidesign audio interfaces: Digi 002 Console, Digi 002 Rack, Digi 003 Console, Digi 003 Rack, Digi 003 Rack+. Written by Takashi Sakamoto.
snd-firewire-lib
  • numerous changes for additional device driver support
  • Handle "unexpected protocol" error with some BeBoB devices, e.g. M-Audio FireWire 1814.
snd-firewire-tascam
  • New driver for TASCAM audio interfaces: FW-1082, FW-1884. Written by Takashi Sakamoto.
snd-oxfw
  • Fix Mackie Onyx Satellite packet discontinuity when device is used in base station mode.
  • Add support for TASCAM FireOne.
  • Fix calculation of MIDI ports.
  • Fix for statically linked (i.e. non-modular) builds.


Linux 4.3

01 November 2015

No functional changes to the FireWire subsystem.


Linux 4.2

30 August 2015

snd-bebob
  • Add support for
Digidesign Mbox 2 Pro
Behringer FCA610, FCA1616
  • Improve BeBoB v3 support (PrismSound Orpheus, Behringer UFX1604, Behringer FCA610).
  • Improved clock source detection. Add SYT-Match support.
snd-firewire-lib
  • Internal changes related to packet handling.
snd-fireworks
  • Fix packet discontinuity with newer firmwares. Also fixed in v4.1.6 and v3.18.21.


Linux 4.1

21 June 2015

No functional changes to the FireWire subsystem.


Linux 4.0

12 April 2015

firewire-core
The vendor ID and model ID in the Configuration ROM root directory of Linux hosts was changed from 0xd00d1e:0x000001 to 0x001f11:0x023901. This change makes firewire-core's local Configuration ROM comply with IEEE's OUI assignment rules.
This has been made possible by Openmoko's granting a range of IDs to the Linux IEEE 1394 subsystem. See IEEE OUI Assignments for additional information. This change cannot have negative impact on any standard protocols, but developers of private protocols may need to adapt if they relied on these root directory entries instead of their own unit directory entries.
The change was also backmerged into v3.12.51.
snd-bebob
  • Fix initialization of some M-Audio devices with Linux on big-endian CPUs. Also fixed in v3.19.5 and v3.18.13.
snd-firewire-lib, snd-bebob, snd-dice, snd-fireworks
  • Fix device reference counting and shutdown. Also fixed in v3.19.2.


Linux 3.0...3.19

July 2011 – February 2015

Support of various devices and controllers was improved. IPv6 support was added to firewire-net (v3.10). New drivers ware added:

  • sbp-target lets a Linux node act as a storage device (v3.5),
  • snd-isight for audio capture through Apple iSight FireWire webcam (v3.0),
  • snd-scs1x, a MIDI driver for Stanton SCS.1d and SCS.1m FireWire DJ controllers (v3.8),
  • snd-dice for audio playback through some audio devices based on TC Applied Technologies' DICE chipset (v3.13), later also for audio capture and MIDI through basically all DICE based devices (v3.19),
  • snd-bebob for audio I/O through BridgeCo DM1000/DM1100/DM1500 based devices with BeBoB firmware (v3.16),
  • snd-fireworks for audio I/O through Echo Digital Audio Fireworks based devices (v3.16),
  • snd-oxfw for audio I/O through Oxford Semiconductor OXFW970/971 based devices (v3.19). snd-oxfw replaced snd-firewire-speakers in v3.19 and snd-scs1x in v4.5.

The audio I/O drivers are an alternative to the existing userspace drivers which the FFADO project provides. While the FFADO drivers can only be used in conjunction with JACK, the kernelspace drivers can be used with any ALSA compatible application. However, the kernelspace drivers only implement PCM streaming and MIDI streaming, whereas device control is meant to be provided by userspace applications like ffado-mixer.

See Release Notes/3.x.


Linux 2.6.30...2.6.39

June 2009 – May 2011

The older ieee1394 driver stack was removed from the kernel after it coexisted as an alternative to the current firewire drivers until kernel 2.6.36 inclusive. Many new features and fixes went into the newer firewire drivers. Some new drivers were added: firewire-net (IPv4 over 1394, replacing the eth1394 driver), nosy (a bus sniffer, formerly maintained outside of the kernel repository), and snd-firewire-speakers (for LaCie FireWire speakers and Griffin FireWave).

See Release Notes/2.6.3x.


Linux 2.6.20...2.6.29

February 2007 – March 2009

The new alternative firewire drivers were added and gradually stabilized. Since the new drivers were not yet feature-complete, the older ieee1394 stack remained preferred for production but received only few minor updates during this time frame.

See Release Notes/2.6.2x.


Linux 2.6.12...2.6.19

June 2005 – November 2006

This is a stabilization phase of the ieee1394 driver stack in Linux 2.6.

See Release Notes/2.6.1x.
