- LINUX ALLOCATED DEVICES
- Maintained by H. Peter Anvin <device@lanana.org>
- Last revised: 3 June 2001
- This list is the Linux Device List, the official registry of allocated
- device numbers and /dev directory nodes for the Linux operating
- system.
- The latest version of this list is available from
- http://www.lanana.org/docs/device-list/ or
- ftp://ftp.kernel.org/pub/linux/docs/device-list/. This version may be
- newer than the one distributed with the Linux kernel.
- The LaTeX version of this document is no longer maintained.
- This document is included by reference into the Filesystem Hierarchy
- Standard (FHS). The FHS is available from http://www.pathname.com/fhs/.
- Allocations marked (68k/Amiga) apply to Linux/68k on the Amiga
- platform only. Allocations marked (68k/Atari) apply to Linux/68k on
- the Atari platform only.
- The symbol {2.6} means the allocation is obsolete and scheduled for
- removal once kernel version 2.6 (or equivalent) is released.
- This document is in the public domain. The author requests, however,
- that semantically altered versions are not distributed without
- permission of the author, assuming the author can be contacted without
- an unreasonable effort.
- In particular, please don't sent patches for this list to Linus, at
- least not without contacting me first.
- I do not have any information about these devices beyond what appears
- on this list. Any such information requests will be deleted without
- reply.
- **** DEVICE DRIVERS AUTHORS PLEASE READ THIS ****
- THE DEVICE REGISTRY IS OFFICIALLY FROZEN FOR LINUS TORVALDS' KERNEL
- TREE. At Linus' request, no more allocations will be made official
- for Linus' kernel tree; the 3 June 2001 version of this list is the
- official final version of this registry. At Alan Cox' request,
- however, the registry will continue to be maintained for the -ac
- series of kernels, and registrations will be accepted.
- To have a major number allocated, or a minor number in situations
- where that applies (e.g. busmice), please contact me with the
- appropriate device information. Also, if you have additional
- information regarding any of the devices listed below, or if I have
- made a mistake, I would greatly appreciate a note.
- I do, however, make a few requests about the nature of your report.
- This is necessary for me to be able to keep this list up to date and
- correct in a timely manner. First of all, *please* send it to the
- correct address... <device@lanana.org>. I receive hundreds of email
- messages a day, so mail sent to other addresses may very well get lost
- in the avalanche. Please put in a descriptive subject, so I can find
- your mail again should I need to. Too many people send me email
- saying just "device number request" in the subject.
- Second, please include a description of the device *in the same format
- as this list*. The reason for this is that it is the only way I have
- found to ensure I have all the requisite information to publish your
- device and avoid conflicts.
- Third, please don't assume that the distributed version of the list is
- up to date. Due to the number of registrations I have to maintain it
- in "batch mode", so there is likely additional registrations that
- haven't been listed yet.
- Finally, sometimes I have to play "namespace police." Please don't be
- offended. I often get submissions for /dev names that would be bound
- to cause conflicts down the road. I am trying to avoid getting in a
- situation where we would have to suffer an incompatible forward
- change. Therefore, please consult with me *before* you make your
- device names and numbers in any way public, at least to the point
- where it would be at all difficult to get them changed.
- Your cooperation is appreciated.
- 0 Unnamed devices (e.g. non-device mounts)
- 0 = reserved as null device number
- 1 char Memory devices
- 1 = /dev/mem Physical memory access
- 2 = /dev/kmem Kernel virtual memory access
- 3 = /dev/null Null device
- 4 = /dev/port I/O port access
- 5 = /dev/zero Null byte source
- 6 = /dev/core OBSOLETE - replaced by /proc/kcore
- 7 = /dev/full Returns ENOSPC on write
- 8 = /dev/random Nondeterministic random number gen.
- 9 = /dev/urandom Faster, less secure random number gen.
- 10 = /dev/aio Asyncronous I/O notification interface
- block RAM disk
- 0 = /dev/ram0 First RAM disk
- 1 = /dev/ram1 Second RAM disk
- ...
- 250 = /dev/initrd Initial RAM disk {2.6}
- Older kernels had /dev/ramdisk (1, 1) here.
- /dev/initrd refers to a RAM disk which was preloaded
- by the boot loader; newer kernels use /dev/ram0 for
- the initrd.
- 2 char Pseudo-TTY masters
- 0 = /dev/ptyp0 First PTY master
- 1 = /dev/ptyp1 Second PTY master
- ...
- 255 = /dev/ptyef 256th PTY master
- Pseudo-tty's are named as follows:
- * Masters are "pty", slaves are "tty";
- * the fourth letter is one of pqrstuvwxyzabcde indicating
- the 1st through 16th series of 16 pseudo-ttys each, and
- * the fifth letter is one of 0123456789abcdef indicating
- the position within the series.
- These are the old-style (BSD) PTY devices; Unix98
- devices are on major 128 and above and use the PTY
- master multiplex (/dev/ptmx) to acquire a PTY on
- demand.

- NOTE: The letter in the device name (d, q, h or u)
- signifies the type of drive: 5.25" Double Density (d),
- 5.25" Quad Density (q), 5.25" High Density (h) or 3.5"
- (any model, u). The use of the capital letters D, H

- **** ADDITIONAL /dev DIRECTORY ENTRIES
- This section details additional entries that should or may exist in
- the /dev directory. It is preferred that symbolic links use the same
- form (absolute or relative) as is indicated here. Links are
- classified as "hard" or "symbolic" depending on the preferred type of
- link; if possible, the indicated type of link should be used.
- Compulsory links
- These links should exist on all systems:
- /dev/fd /proc/self/fd symbolic File descriptors
- /dev/stdin fd/0 symbolic stdin file descriptor
- /dev/stdout fd/1 symbolic stdout file descriptor
- /dev/stderr fd/2 symbolic stderr file descriptor
- /dev/nfsd socksys symbolic Required by iBCS-2
- /dev/X0R null symbolic Required by iBCS-2
- Note: /dev/X0R is <letter X>-<digit 0>-<letter R>.
- Recommended links
- It is recommended that these links exist on all systems:
- /dev/core /proc/kcore symbolic Backward compatibility
- /dev/ramdisk ram0 symbolic Backward compatibility
- /dev/ftape qft0 symbolic Backward compatibility
- /dev/bttv0 video0 symbolic Backward compatibility
- /dev/radio radio0 symbolic Backward compatibility
- /dev/i2o* /dev/i2o/* symbolic Backward compatibility
- /dev/scd? sr? hard Alternate SCSI CD-ROM name
- Locally defined links
- The following links may be established locally to conform to the
- configuration of the system. This is merely a tabulation of existing
- practice, and does not constitute a recommendation. However, if they
- exist, they should have the following uses.
- /dev/mouse mouse port symbolic Current mouse device
- /dev/tape tape device symbolic Current tape device
- /dev/cdrom CD-ROM device symbolic Current CD-ROM device
- /dev/cdwriter CD-writer symbolic Current CD-writer device
- /dev/scanner scanner symbolic Current scanner device
- /dev/modem modem port symbolic Current dialout device
- /dev/root root device symbolic Current root filesystem
- /dev/swap swap device symbolic Current swap device
- /dev/modem should not be used for a modem which supports dialin as
- well as dialout, as it tends to cause lock file problems. If it
- exists, /dev/modem should point to the appropriate primary TTY device
- (the use of the alternate callout devices is deprecated).
- For SCSI devices, /dev/tape and /dev/cdrom should point to the
- ``cooked'' devices (/dev/st* and /dev/sr*, respectively), whereas
- /dev/cdwriter and /dev/scanner should point to the appropriate generic
- SCSI devices (/dev/sg*).
- /dev/mouse may point to a primary serial TTY device, a hardware mouse
- device, or a socket for a mouse driver program (e.g. /dev/gpmdata).
- Sockets and pipes
- Non-transient sockets and named pipes may exist in /dev. Common entries are:
- /dev/printer socket lpd local socket
- /dev/log socket syslog local socket
- /dev/gpmdata socket gpm mouse multiplexer
- Mount points
- The following names are reserved for mounting special filesystems
- under /dev. These special filesystems provide kernel interfaces that
- cannot be provided with standard device nodes.
- /dev/pts devpts PTY slave filesystem
- /dev/shm shmfs POSIX shared memory maintenance access
- **** TERMINAL DEVICES
- Terminal, or TTY devices are a special class of character devices. A
- terminal device is any device that could act as a controlling terminal
- for a session; this includes virtual consoles, serial ports, and
- pseudoterminals (PTYs).
- All terminal devices share a common set of capabilities known as line
- diciplines; these include the common terminal line dicipline as well
- as SLIP and PPP modes.
- All terminal devices are named similarly; this section explains the
- naming and use of the various types of TTYs. Note that the naming
- conventions include several historical warts; some of these are
- Linux-specific, some were inherited from other systems, and some
- reflect Linux outgrowing a borrowed convention.
- A hash mark (#) in a device name is used here to indicate a decimal
- number without leading zeroes.
- Virtual consoles and the console device
- Virtual consoles are full-screen terminal displays on the system video
- monitor. Virtual consoles are named /dev/tty#, with numbering
- starting at /dev/tty1; /dev/tty0 is the current virtual console.
- /dev/tty0 is the device that should be used to access the system video
- card on those architectures for which the frame buffer devices
- (/dev/fb*) are not applicable. Do not use /dev/console
- for this purpose.
- The console device, /dev/console, is the device to which system
- messages should be sent, and on which logins should be permitted in
- single-user mode. Starting with Linux 2.1.71, /dev/console is managed
- by the kernel; for previous versions it should be a symbolic link to
- either /dev/tty0, a specific virtual console such as /dev/tty1, or to
- a serial port primary (tty*, not cu*) device, depending on the
- configuration of the system.
- Serial ports
- Serial ports are RS-232 serial ports and any device which simulates
- one, either in hardware (such as internal modems) or in software (such
- as the ISDN driver.) Under Linux, each serial ports has two device
- names, the primary or callin device and the alternate or callout one.
- Each kind of device is indicated by a different letter. For any
- letter X, the names of the devices are /dev/ttyX# and /dev/cux#,
- respectively; for historical reasons, /dev/ttyS# and /dev/ttyC#
- correspond to /dev/cua# and /dev/cub#. In the future, it should be
- expected that multiple letters will be used; all letters will be upper
- case for the "tty" device (e.g. /dev/ttyDP#) and lower case for the
- "cu" device (e.g. /dev/cudp#).
- The names /dev/ttyQ# and /dev/cuq# are reserved for local use.
- The alternate devices provide for kernel-based exclusion and somewhat
- different defaults than the primary devices. Their main purpose is to
- allow the use of serial ports with programs with no inherent or broken
- support for serial ports. Their use is deprecated, and they may be
- removed from a future version of Linux.
- Arbitration of serial ports is provided by the use of lock files with
- the names /var/lock/LCK..ttyX#. The contents of the lock file should
- be the PID of the locking process as an ASCII number.
- It is common practice to install links such as /dev/modem
- which point to serial ports. In order to ensure proper locking in the
- presence of these links, it is recommended that software chase
- symlinks and lock all possible names; additionally, it is recommended
- that a lock file be installed with the corresponding alternate
- device. In order to avoid deadlocks, it is recommended that the locks
- are acquired in the following order, and released in the reverse:
- 1. The symbolic link name, if any (/var/lock/LCK..modem)
- 2. The "tty" name (/var/lock/LCK..ttyS2)
- 3. The alternate device name (/var/lock/LCK..cua2)
- In the case of nested symbolic links, the lock files should be
- installed in the order the symlinks are resolved.
- Under no circumstances should an application hold a lock while waiting
- for another to be released. In addition, applications which attempt
- to create lock files for the corresponding alternate device names
- should take into account the possibility of being used on a non-serial
- port TTY, for which no alternate device would exist.
- Pseudoterminals (PTYs)
- Pseudoterminals, or PTYs, are used to create login sessions or provide
- other capabilities requiring a TTY line dicipline (including SLIP or
- PPP capability) to arbitrary data-generation processes. Each PTY has
- a master side, named /dev/pty[p-za-e][0-9a-f], and a slave side, named
- /dev/tty[p-za-e][0-9a-f]. The kernel arbitrates the use of PTYs by
- allowing each master side to be opened only once.
- Once the master side has been opened, the corresponding slave device
- can be used in the same manner as any TTY device. The master and
- slave devices are connected by the kernel, generating the equivalent
- of a bidirectional pipe with TTY capabilities.
- Recent versions of the Linux kernels and GNU libc contain support for
- the System V/Unix98 naming scheme for PTYs, which assigns a common
- device, /dev/ptmx, to all the masters (opening it will automatically
- give you a previously unassigned PTY) and a subdirectory, /dev/pts,
- for the slaves; the slaves are named with decimal integers (/dev/pts/#
- in our notation). This removes the problem of exhausting the
- namespace and enables the kernel to automatically create the device
- nodes for the slaves on demand using the "devpts" filesystem.
