LINUX ALLOCATED DEVICES (4.x+ version)
|
||
|
|
|
||
|
|
This list is the Linux Device List, the official registry of allocated
|
||
|
|
device numbers and /dev directory nodes for the Linux operating
|
||
|
|
system.
|
||
|

The LaTeX version of this document is no longer maintained, nor is
|
||
|
|
the document that used to reside at lanana.org. This version in the
|
||
|
|
mainline Linux kernel is the master document. Updates shall be sent
|
||
|
|
as patches to the kernel maintainers (see the SubmittingPatches document).
|
||
|
|
Specifically explore the sections titled "CHAR and MISC DRIVERS", and
|
||
|
|
"BLOCK LAYER" in the MAINTAINERS file to find the right maintainers
|
||
|
|
to involve for character and block devices.

**** DEVICE DRIVERS AUTHORS PLEASE READ THIS ****
|
||
|
|
|
||
|
|
Linux now has extensive support for dynamic allocation of device numbering
|
||
|
|
and can use sysfs and udev (systemd) 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.
|
||
|
|
|
||
|
|
To have a major number allocated, or a minor number in situations
|
||
|
|
where that applies (e.g. busmice), please submit a patch and send to
|
||
|
|
the authors as indicated above.
|
||
|
|
|
||
|
|
Keep the description of the device *in the same format
|
||
|
|
as this list*. The reason for this is that it is the only way we have
|
||
|
|
found to ensure we have all the requisite information to publish your
|
||
|
|
device and avoid conflicts.
|
||
|
|
|
||
|
|
Finally, sometimes we have to play "namespace police." Please don't be
|
||
|
|
offended. We often get submissions for /dev names that would be bound
|
||
|
|
to cause conflicts down the road. We are trying to avoid getting in a
|
||
|
|
situation where we would have to suffer an incompatible forward
|
||
|
|
change. Therefore, please consult with us *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.

|
|
10 = /dev/aio Asynchronous I/O notification interface
|

||
|
|
...
|
||
|
|
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.

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.

These are the old-style (BSD) PTY devices; Unix98
|
||
|
|
devices are on major 136 and above.

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.

|
|
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.

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.

|
|
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).
|

|
||
|
|
...
|
||
|
|
|
||
|
|
"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 EVMS driver uses a layered, plug-in model to provide
|
||
|
|
unparalleled flexibility and extensibility in managing
|
||
|
|
storage. This allows for easy expansion or customization
|
||
|
|
of various levels of volume management. Requested by
|
||
|
|
Mark Peloquin (peloquin at us.ibm.com).
|
||
|
|
|
||
|
|
Note: EVMS populates and manages all the devnodes in
|
||
|
|
/dev/evms.

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.

|
|
exist, they should have the following uses.
|
||
|
|
|
||
|
|
/dev/mouse mouse port symbolic Current mouse device

/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).
|
||
|
|
|
||

**** 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.
|
||
|
