LINUX ALLOCATED DEVICES (2.6+ version)
|
|
|
|
Maintained by Alan Cox <device@lanana.org>
|
|
|
|
Last revised: 6th April 2009
|
|
|
|
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The LaTeX version of this document is no longer maintained.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The symbol {2.6} means the allocation is obsolete and scheduled for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. Some of these
|
|
allocations have already been removed.
|
|
|
|
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 ****
|
|
|
|
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.
|
|
|
|
Fourth, remember that Linux now has extensive support for dynamic allocation
|
|
of device numbering and can use sysfs and udev to handle the naming needs.
|
|
There are still some exceptions in the serial and boot device area. Before
|
|
asking for a device number make sure you actually need one.
|
|
|
|
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
|
|
See block major 144, 145, 146 for expansion areas.
|
|
|
|
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 Asynchronous I/O notification interface
|
|
11 = /dev/kmsg Writes to this come out as printk's
|
|
12 = /dev/oldmem Used by crashdump kernels to access
|
|
the memory of the kernel that crashed.
|
|
|
|
1 block RAM disk
|
|
0 = /dev/ram0 First RAM disk
|
|
1 = /dev/ram1 Second RAM disk
|
|
...
|
|
250 = /dev/initrd Initial RAM disk
|
|
|
|
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.
|
|
|
|
2 block Floppy disks
|
|
0 = /dev/fd0 Controller 0, drive 0, autodetect
|
|
1 = /dev/fd1 Controller 0, drive 1, autodetect

130 = /dev/fd6 Controller 1, drive 2, autodetect
|
|
131 = /dev/fd7 Controller 1, drive 3, autodetect
|
|
|
|
To specify format, add to the autodetect device number:
|
|
0 = /dev/fd? Autodetect format
|
|
4 = /dev/fd?d360 5.25" 360K in a 360K drive(1)
|

|
|
|
|
36 = /dev/fd?CompaQ Compaq 2880K drive; obsolete?
|
|
|
|
(1) Autodetectable format
|
|
(2) Autodetectable format in a Double Density (720K) drive only
|
|
(3) Autodetectable format in a High Density (1440K) drive only
|
|
|
|
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
|
|
and E for the 3.5" models have been deprecated, since
|
|
the drive type is insignificant for these devices.
|
|
|
|
3 char Pseudo-TTY slaves
|
|
0 = /dev/ttyp0 First PTY slave
|
|
1 = /dev/ttyp1 Second PTY slave
|
|
...
|
|
255 = /dev/ttyef 256th PTY slave
|
|
|
|
These are the old-style (BSD) PTY devices; Unix98
|
|
devices are on major 136 and above.
|
|
|
|
3 block First MFM, RLL and IDE hard disk/CD-ROM interface
|
|
0 = /dev/hda Master: whole disk (or CD-ROM)
|
|
64 = /dev/hdb Slave: whole disk (or CD-ROM)
|
|
|
|
For partitions, add to the whole disk device number:
|
|
0 = /dev/hd? Whole disk
|
|
1 = /dev/hd?1 First partition
|
|
2 = /dev/hd?2 Second partition
|
|
...
|
|
63 = /dev/hd?63 63rd partition
|
|
|
|
For Linux/i386, partitions 1-4 are the primary
|
|
partitions, and 5 and above are logical partitions.
|
|
Other versions of Linux use partitioning schemes
|
|
appropriate to their respective architectures.
|
|
|
|
4 char TTY devices
|
|
0 = /dev/tty0 Current virtual console
|
|
|
|
1 = /dev/tty1 First virtual console
|
|
...
|
|
63 = /dev/tty63 63rd virtual console
|
|
64 = /dev/ttyS0 First UART serial port
|
|
...
|
|
255 = /dev/ttyS191 192nd UART serial port
|
|
|
|
UART serial ports refer to 8250/16450/16550 series devices.
|
|
|
|
Older versions of the Linux kernel used this major
|
|
number for BSD PTY devices. As of Linux 2.1.115, this
|
|
is no longer supported. Use major numbers 2 and 3.
|
|
|
|
4 block Aliases for dynamically allocated major devices to be used
|
|
when its not possible to create the real device nodes
|
|
because the root filesystem is mounted read-only.
|
|
|
|
0 = /dev/root
|
|
|
|
5 char Alternate TTY devices
|
|
0 = /dev/tty Current TTY device
|
|
1 = /dev/console System console
|
|
2 = /dev/ptmx PTY master multiplex
|
|
64 = /dev/cua0 Callout device for ttyS0
|
|
...
|
|
255 = /dev/cua191 Callout device for ttyS191
|
|
|
|
(5,1) is /dev/console starting with Linux 2.1.71. See
|
|
the section on terminal devices for more information
|
|
on /dev/console.
|
|
|
|
6 char Parallel printer devices
|
|
0 = /dev/lp0 Parallel printer on parport0
|
|
1 = /dev/lp1 Parallel printer on parport1
|
|
...
|
|
|
|
Current Linux kernels no longer have a fixed mapping
|
|
between parallel ports and I/O addresses. Instead,
|
|
they are redirected through the parport multiplex layer.
|
|
|
|
7 char Virtual console capture devices
|
|
0 = /dev/vcs Current vc text contents
|
|
1 = /dev/vcs1 tty1 text contents
|
|
...
|
|
63 = /dev/vcs63 tty63 text contents
|
|
128 = /dev/vcsa Current vc text/attribute contents
|
|
129 = /dev/vcsa1 tty1 text/attribute contents
|
|
...
|
|
191 = /dev/vcsa63 tty63 text/attribute contents
|
|
|
|
NOTE: These devices permit both read and write access.
|
|
|
|
7 block Loopback devices
|
|
0 = /dev/loop0 First loop device
|
|
1 = /dev/loop1 Second loop device
|
|
...
|
|
|
|
The loop devices are used to mount filesystems not
|
|
associated with block devices. The binding to the
|
|
loop devices is handled by mount(8) or losetup(8).
|
|
|
|
8 block SCSI disk devices (0-15)
|
|
0 = /dev/sda First SCSI disk whole disk
|
|
16 = /dev/sdb Second SCSI disk whole disk
|
|
32 = /dev/sdc Third SCSI disk whole disk
|
|
...
|
|
240 = /dev/sdp Sixteenth SCSI disk whole disk
|
|
|
|
Partitions are handled in the same way as for IDE
|
|
disks (see major number 3) except that the limit on
|
|
partitions is 15.
|
|
|
|
9 char SCSI tape devices
|
|
0 = /dev/st0 First SCSI tape, mode 0
|
|
1 = /dev/st1 Second SCSI tape, mode 0
|
|
...
|
|
32 = /dev/st0l First SCSI tape, mode 1
|
|
33 = /dev/st1l Second SCSI tape, mode 1
|
|
...
|
|
64 = /dev/st0m First SCSI tape, mode 2
|
|
65 = /dev/st1m Second SCSI tape, mode 2
|
|
...
|
|
96 = /dev/st0a First SCSI tape, mode 3
|
|
97 = /dev/st1a Second SCSI tape, mode 3
|
|
...
|
|
128 = /dev/nst0 First SCSI tape, mode 0, no rewind
|
|
129 = /dev/nst1 Second SCSI tape, mode 0, no rewind
|
|
...
|
|
160 = /dev/nst0l First SCSI tape, mode 1, no rewind
|
|
161 = /dev/nst1l Second SCSI tape, mode 1, no rewind
|
|
...
|
|
192 = /dev/nst0m First SCSI tape, mode 2, no rewind
|
|
193 = /dev/nst1m Second SCSI tape, mode 2, no rewind
|
|
...
|
|
224 = /dev/nst0a First SCSI tape, mode 3, no rewind
|
|
225 = /dev/nst1a Second SCSI tape, mode 3, no rewind
|
|
...
|
|
|
|
"No rewind" refers to the omission of the default
|
|
automatic rewind on device close. The MTREW or MTOFFL
|
|
ioctl()'s can be used to rewind the tape regardless of
|
|
the device used to access it.
|
|
|
|
9 block Metadisk (RAID) devices
|
|
0 = /dev/md0 First metadisk group
|
|
1 = /dev/md1 Second metadisk group
|
|
...
|
|
|
|
The metadisk driver is used to span a
|
|
filesystem across multiple physical disks.
|
|

This number is intended for use in sample code, as

should never be used for a device driver that is being

|
distributed; either obtain an official number or use

the local/experimental range. The sudden addition or

removal of a driver with this number should not cause

ill effects to the system (bugs excepted.)

IN PARTICULAR, ANY DISTRIBUTION WHICH CONTAINS A
|

to mounting filesystems over the net, swapping over

The OnStream SC-x0 SCSI tapes do not support the
|
|
standard SCSI SASD command set and therefore need
|
|
their own driver "osst". Note that the IDE, USB (and
|
|
maybe ParPort) versions may be driven via ide-scsi or
|
|
usb-storage SCSI emulation and this osst device and
|
|
driver as well. The ADR-x0 drives are QIC-157
|
|
compliant and don't need osst.

**** 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 tmpfs 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
|
|
disciplines; these include the common terminal line discipline 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 discipline (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.
