LINUX ALLOCATED DEVICES (2.6+ version) Maintained by Alan Cox <device@lanana.org> Last revised: 6th April 2009This list is the Linux Device List, the official registry of allocateddevice numbers and /dev directory nodes for the Linux operatingsystem.The latest version of this list is available fromhttp://www.lanana.org/docs/device-list/ orftp://ftp.kernel.org/pub/linux/docs/device-list/. This version may benewer than the one distributed with the Linux kernel.The LaTeX version of this document is no longer maintained.This document is included by reference into the Filesystem HierarchyStandard (FHS). The FHS is available from http://www.pathname.com/fhs/.Allocations marked (68k/Amiga) apply to Linux/68k on the Amigaplatform only.Allocations marked (68k/Atari) apply to Linux/68k onthe Atari platform only.The symbol {2.6} means the allocation is obsolete and scheduled forremoval once kernel version 2.6 (or equivalent) is released. Some of theseallocations have already been removed.This document is in the public domain.The author requests, however,that semantically altered versions are not distributed withoutpermission of the author, assuming the author can be contacted withoutan unreasonable effort.In particular, please don't sent patches for this list to Linus, atleast not without contacting me first.I do not have any information about these devices beyond what appearson this list. Any such information requests will be deleted withoutreply. **** DEVICE DRIVERS AUTHORS PLEASE READ THIS ****To have a major number allocated, or a minor number in situationswhere that applies (e.g. busmice), please contact me with theappropriate device information. Also, if you have additionalinformation regarding any of the devices listed below, or if I havemade 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 andcorrect in a timely manner. First of all, *please* send it to thecorrect address... <device@lanana.org>. I receive hundreds of emailmessages a day, so mail sent to other addresses may very well get lostin the avalanche. Please put in a descriptive subject, so I can findyour mail again should I need to. Too many people send me emailsaying just "device number request" in the subject.Second, please include a description of the device *in the same formatas this list*.The reason for this is that it is the only way I havefound to ensure I have all the requisite information to publish yourdevice and avoid conflicts.Third, please don't assume that the distributed version of the list isup to date. Due to the number of registrations I have to maintain itin "batch mode", so there is likely additional registrations thathaven't been listed yet.Fourth, remember that Linux now has extensive support for dynamic allocationof 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. Beforeasking for a device number make sure you actually need one.Finally, sometimes I have to play "namespace police." Please don't beoffended. I often get submissions for /dev names that would be boundto cause conflicts down the road. I am trying to avoid getting in asituation where we would have to suffer an incompatible forwardchange. Therefore, please consult with me *before* you make yourdevice names and numbers in any way public, at least to the pointwhere it would be at all difficult to get them changed.Your cooperation is appreciated. 0Unnamed devices (e.g. non-device mounts) 0 = reserved as null device numberSee block major 144, 145, 146 for expansion areas. 1 charMemory devices 1 = /dev/memPhysical memory access 2 = /dev/kmemKernel virtual memory access 3 = /dev/nullNull device 4 = /dev/portI/O port access 5 = /dev/zeroNull byte source 6 = /dev/coreOBSOLETE - replaced by /proc/kcore 7 = /dev/fullReturns ENOSPC on write 8 = /dev/randomNondeterministic random number gen. 9 = /dev/urandomFaster, less secure random number gen. 10 = /dev/aioAsynchronous I/O notification interface 11 = /dev/kmsgWrites to this come out as printk's 12 = /dev/oldmemUsed by crashdump kernels to accessthe memory of the kernel that crashed. 1 blockRAM disk 0 = /dev/ram0First RAM disk 1 = /dev/ram1Second RAM disk ...250 = /dev/initrdInitial RAM diskOlder kernels had /dev/ramdisk (1, 1) here./dev/initrd refers to a RAM disk which was preloadedby the boot loader; newer kernels use /dev/ram0 forthe initrd. 2 charPseudo-TTY masters 0 = /dev/ptyp0First PTY master 1 = /dev/ptyp1Second PTY master ...255 = /dev/ptyef256th PTY masterPseudo-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; Unix98devices are on major 128 and above and use the PTYmaster multiplex (/dev/ptmx) to acquire a PTY ondemand. 2 blockFloppy disks 0 = /dev/fd0Controller 0, drive 0, autodetect 1 = /dev/fd1Controller 0, drive 1, autodetect 2 = /dev/fd2Controller 0, drive 2, autodetect 3 = /dev/fd3Controller 0, drive 3, autodetect128 = /dev/fd4Controller 1, drive 0, autodetect129 = /dev/fd5Controller 1, drive 1, autodetect130 = /dev/fd6Controller 1, drive 2, autodetect131 = /dev/fd7Controller 1, drive 3, autodetectTo specify format, add to the autodetect device number: 0 = /dev/fd?Autodetect format 4 = /dev/fd?d3605.25" 360K in a 360K drive(1) 20 = /dev/fd?h3605.25" 360K in a 1200K drive(1) 48 = /dev/fd?h4105.25" 410K in a 1200K drive 64 = /dev/fd?h4205.25" 420K in a 1200K drive 24 = /dev/fd?h7205.25" 720K in a 1200K drive 80 = /dev/fd?h8805.25" 880K in a 1200K drive(1) 8 = /dev/fd?h12005.25" 1200K in a 1200K drive(1) 40 = /dev/fd?h14405.25" 1440K in a 1200K drive(1) 56 = /dev/fd?h14765.25" 1476K in a 1200K drive 72 = /dev/fd?h14945.25" 1494K in a 1200K drive 92 = /dev/fd?h16005.25" 1600K in a 1200K drive(1) 12 = /dev/fd?u3603.5" 360K Double Density(2) 16 = /dev/fd?u7203.5" 720K Double Density(1)120 = /dev/fd?u8003.5" 800K Double Density(2) 52 = /dev/fd?u8203.5" 820K Double Density 68 = /dev/fd?u8303.5" 830K Double Density 84 = /dev/fd?u10403.5" 1040K Double Density(1) 88 = /dev/fd?u11203.5" 1120K Double Density(1) 28 = /dev/fd?u14403.5" 1440K High Density(1)124 = /dev/fd?u16003.5" 1600K High Density(1) 44 = /dev/fd?u16803.5" 1680K High Density(3) 60 = /dev/fd?u17223.5" 1722K High Density 76 = /dev/fd?u17433.5" 1743K High Density 96 = /dev/fd?u17603.5" 1760K High Density116 = /dev/fd?u18403.5" 1840K High Density(3)100 = /dev/fd?u19203.5" 1920K High Density(1) 32 = /dev/fd?u28803.5" 2880K Extra Density(1)104 = /dev/fd?u32003.5" 3200K Extra Density108 = /dev/fd?u35203.5" 3520K Extra Density112 = /dev/fd?u38403.5" 3840K Extra Density(1) 36 = /dev/fd?CompaQCompaq 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 onlyNOTE: 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).

These special filesystems provide kernel interfaces thatcannot be provided with standard device nodes./dev/ptsdevptsPTY slave filesystem/dev/shmtmpfsPOSIX shared memory maintenance access ****TERMINAL DEVICESTerminal, or TTY devices are a special class of character devices. Aterminal device is any device that could act as a controlling terminalfor a session; this includes virtual consoles, serial ports, andpseudoterminals (PTYs).All terminal devices share a common set of capabilities known as linedisciplines; these include the common terminal line discipline as wellas SLIP and PPP modes.All terminal devices are named similarly; this section explains thenaming and use of the various types of TTYs. Note that the namingconventions include several historical warts; some of these areLinux-specific, some were inherited from other systems, and somereflect Linux outgrowing a borrowed convention.A hash mark (#) in a device name is used here to indicate a decimalnumber without leading zeroes.Virtual consoles and the console deviceVirtual consoles are full-screen terminal displays on the system videomonitor. Virtual consoles are named /dev/tty#, with numberingstarting at /dev/tty1; /dev/tty0 is the current virtual console./dev/tty0 is the device that should be used to access the system videocard on those architectures for which the frame buffer devices(/dev/fb*) are not applicable.Do not use /dev/consolefor this purpose.The console device, /dev/console, is the device to which systemmessages should be sent, and on which logins should be permitted insingle-user mode. Starting with Linux 2.1.71, /dev/console is managedby the kernel; for previous versions it should be a symbolic link toeither /dev/tty0, a specific virtual console such as /dev/tty1, or toa serial port primary (tty*, not cu*) device, depending on theconfiguration of the system.Serial portsSerial ports are RS-232 serial ports and any device which simulatesone, either in hardware (such as internal modems) or in software (suchas the ISDN driver.) Under Linux, each serial ports has two devicenames, the primary or callin device and the alternate or callout one.Each kind of device is indicated by a different letter. For anyletter 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 beexpected that multiple letters will be used; all letters will be uppercase 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 somewhatdifferent defaults than the primary devices. Their main purpose is toallow the use of serial ports with programs with no inherent or brokensupport for serial ports. Their use is deprecated, and they may beremoved from a future version of Linux.Arbitration of serial ports is provided by the use of lock files withthe names /var/lock/LCK..ttyX#. The contents of the lock file shouldbe the PID of the locking process as an ASCII number.It is common practice to install links such as /dev/modemwhich point to serial ports. In order to ensure proper locking in thepresence of these links, it is recommended that software chasesymlinks and lock all possible names; additionally, it is recommendedthat a lock file be installed with the corresponding alternatedevice. In order to avoid deadlocks, it is recommended that the locksare 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 beinstalled in the order the symlinks are resolved.Under no circumstances should an application hold a lock while waitingfor another to be released. In addition, applications which attemptto create lock files for the corresponding alternate device namesshould take into account the possibility of being used on a non-serialport TTY, for which no alternate device would exist.Pseudoterminals (PTYs)Pseudoterminals, or PTYs, are used to create login sessions or provideother capabilities requiring a TTY line discipline (including SLIP orPPP capability) to arbitrary data-generation processes. Each PTY hasa 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 byallowing each master side to be opened only once.Once the master side has been opened, the corresponding slave devicecan be used in the same manner as any TTY device. The master andslave devices are connected by the kernel, generating the equivalentof a bidirectional pipe with TTY capabilities.Recent versions of the Linux kernels and GNU libc contain support forthe System V/Unix98 naming scheme for PTYs, which assigns a commondevice, /dev/ptmx, to all the masters (opening it will automaticallygive 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 thenamespace and enables the kernel to automatically create the devicenodes for the slaves on demand using the "devpts" filesystem.
