1 2 LINUX ALLOCATED DEVICES (2.6+ version) 3 4 Maintained by Torben Mathiasen <device@lanana.org> 5 6 Last revised: 29 November 2006 7 8This list is the Linux Device List, the official registry of allocated 9device numbers and /dev directory nodes for the Linux operating 10system. 11 12The latest version of this list is available from 13http://www.lanana.org/docs/device-list/ or 14ftp://ftp.kernel.org/pub/linux/docs/device-list/. This version may be 15newer than the one distributed with the Linux kernel. 16 17The LaTeX version of this document is no longer maintained. 18 19This document is included by reference into the Filesystem Hierarchy 20Standard (FHS). The FHS is available from http://www.pathname.com/fhs/. 21 22Allocations marked (68k/Amiga) apply to Linux/68k on the Amiga 23platform only. Allocations marked (68k/Atari) apply to Linux/68k on 24the Atari platform only. 25 26The symbol {2.6} means the allocation is obsolete and scheduled for 27removal once kernel version 2.6 (or equivalent) is released. Some of these 28allocations have already been removed. 29 30This document is in the public domain. The author requests, however, 31that semantically altered versions are not distributed without 32permission of the author, assuming the author can be contacted without 33an unreasonable effort. 34 35In particular, please don't sent patches for this list to Linus, at 36least not without contacting me first. 37 38I do not have any information about these devices beyond what appears 39on this list. Any such information requests will be deleted without 40reply. 41 42 43 **** DEVICE DRIVERS AUTHORS PLEASE READ THIS **** 44 45To have a major number allocated, or a minor number in situations 46where that applies (e.g. busmice), please contact me with the 47appropriate device information. Also, if you have additional 48information regarding any of the devices listed below, or if I have 49made a mistake, I would greatly appreciate a note. 50 51I do, however, make a few requests about the nature of your report. 52This is necessary for me to be able to keep this list up to date and 53correct in a timely manner. First of all, *please* send it to the 54correct address... <device@lanana.org>. I receive hundreds of email 55messages a day, so mail sent to other addresses may very well get lost 56in the avalanche. Please put in a descriptive subject, so I can find 57your mail again should I need to. Too many people send me email 58saying just "device number request" in the subject. 59 60Second, please include a description of the device *in the same format 61as this list*. The reason for this is that it is the only way I have 62found to ensure I have all the requisite information to publish your 63device and avoid conflicts. 64 65Third, please don't assume that the distributed version of the list is 66up to date. Due to the number of registrations I have to maintain it 67in "batch mode", so there is likely additional registrations that 68haven't been listed yet. 69 70Finally, sometimes I have to play "namespace police." Please don't be 71offended. I often get submissions for /dev names that would be bound 72to cause conflicts down the road. I am trying to avoid getting in a 73situation where we would have to suffer an incompatible forward 74change. Therefore, please consult with me *before* you make your 75device names and numbers in any way public, at least to the point 76where it would be at all difficult to get them changed. 77 78Your cooperation is appreciated. 79 80 81 0 Unnamed devices (e.g. non-device mounts) 82 0 = reserved as null device number 83 See block major 144, 145, 146 for expansion areas. 84 85 1 char Memory devices 86 1 = /dev/mem Physical memory access 87 2 = /dev/kmem Kernel virtual memory access 88 3 = /dev/null Null device 89 4 = /dev/port I/O port access 90 5 = /dev/zero Null byte source 91 6 = /dev/core OBSOLETE - replaced by /proc/kcore 92 7 = /dev/full Returns ENOSPC on write 93 8 = /dev/random Nondeterministic random number gen. 94 9 = /dev/urandom Faster, less secure random number gen. 95 10 = /dev/aio Asynchronous I/O notification interface 96 11 = /dev/kmsg Writes to this come out as printk's 97 12 = /dev/oldmem Used by crashdump kernels to access 98 the memory of the kernel that crashed. 99 100 1 block RAM disk 101 0 = /dev/ram0 First RAM disk 102 1 = /dev/ram1 Second RAM disk 103 ... 104 250 = /dev/initrd Initial RAM disk {2.6} 105 106 Older kernels had /dev/ramdisk (1, 1) here. 107 /dev/initrd refers to a RAM disk which was preloaded 108 by the boot loader; newer kernels use /dev/ram0 for 109 the initrd. 110 111 2 char Pseudo-TTY masters 112 0 = /dev/ptyp0 First PTY master 113 1 = /dev/ptyp1 Second PTY master 114 ... 115 255 = /dev/ptyef 256th PTY master 116 117 Pseudo-tty's are named as follows: 118 * Masters are "pty", slaves are "tty"; 119 * the fourth letter is one of pqrstuvwxyzabcde indicating 120 the 1st through 16th series of 16 pseudo-ttys each, and 121 * the fifth letter is one of 0123456789abcdef indicating 122 the position within the series. 123 124 These are the old-style (BSD) PTY devices; Unix98 125 devices are on major 128 and above and use the PTY 126 master multiplex (/dev/ptmx) to acquire a PTY on 127 demand. 128 129 2 block Floppy disks 130 0 = /dev/fd0 Controller 0, drive 0, autodetect 131 1 = /dev/fd1 Controller 0, drive 1, autodetect 132 2 = /dev/fd2 Controller 0, drive 2, autodetect 133 3 = /dev/fd3 Controller 0, drive 3, autodetect 134 128 = /dev/fd4 Controller 1, drive 0, autodetect 135 129 = /dev/fd5 Controller 1, drive 1, autodetect 136 130 = /dev/fd6 Controller 1, drive 2, autodetect 137 131 = /dev/fd7 Controller 1, drive 3, autodetect 138 139 To specify format, add to the autodetect device number: 140 0 = /dev/fd?

If it 3200exists, /dev/modem should point to the appropriate primary TTY device 3201(the use of the alternate callout devices is deprecated). 3202 3203For SCSI devices, /dev/tape and /dev/cdrom should point to the 3204``cooked'' devices (/dev/st* and /dev/sr*, respectively), whereas 3205/dev/cdwriter and /dev/scanner should point to the appropriate generic 3206SCSI devices (/dev/sg*). 3207 3208/dev/mouse may point to a primary serial TTY device, a hardware mouse 3209device, or a socket for a mouse driver program (e.g. /dev/gpmdata). 3210 3211 Sockets and pipes 3212 3213Non-transient sockets and named pipes may exist in /dev.

A 3231terminal device is any device that could act as a controlling terminal 3232for a session; this includes virtual consoles, serial ports, and 3233pseudoterminals (PTYs). 3234 3235All terminal devices share a common set of capabilities known as line 3236disciplines; these include the common terminal line discipline as well 3237as SLIP and PPP modes. 3238 3239All terminal devices are named similarly; this section explains the 3240naming and use of the various types of TTYs. Note that the naming 3241conventions include several historical warts; some of these are 3242Linux-specific, some were inherited from other systems, and some 3243reflect Linux outgrowing a borrowed convention. 3244 3245A hash mark (#) in a device name is used here to indicate a decimal 3246number without leading zeroes. 3247 3248 Virtual consoles and the console device 3249 3250Virtual consoles are full-screen terminal displays on the system video 3251monitor. Virtual consoles are named /dev/tty#, with numbering 3252starting at /dev/tty1; /dev/tty0 is the current virtual console. 3253/dev/tty0 is the device that should be used to access the system video 3254card on those architectures for which the frame buffer devices 3255(/dev/fb*) are not applicable. Do not use /dev/console 3256for this purpose. 3257 3258The console device, /dev/console, is the device to which system 3259messages should be sent, and on which logins should be permitted in 3260single-user mode. Starting with Linux 2.1.71, /dev/console is managed 3261by the kernel; for previous versions it should be a symbolic link to 3262either /dev/tty0, a specific virtual console such as /dev/tty1, or to 3263a serial port primary (tty*, not cu*) device, depending on the 3264configuration of the system. 3265 3266 Serial ports 3267 3268Serial ports are RS-232 serial ports and any device which simulates 3269one, either in hardware (such as internal modems) or in software (such 3270as the ISDN driver.) Under Linux, each serial ports has two device 3271names, the primary or callin device and the alternate or callout one. 3272Each kind of device is indicated by a different letter. For any 3273letter X, the names of the devices are /dev/ttyX# and /dev/cux#, 3274respectively; for historical reasons, /dev/ttyS# and /dev/ttyC# 3275correspond to /dev/cua# and /dev/cub#. In the future, it should be 3276expected that multiple letters will be used; all letters will be upper 3277case for the "tty" device (e.g. /dev/ttyDP#) and lower case for the 3278"cu" device (e.g. /dev/cudp#). 3279 3280The names /dev/ttyQ# and /dev/cuq# are reserved for local use. 3281 3282The alternate devices provide for kernel-based exclusion and somewhat 3283different defaults than the primary devices. Their main purpose is to 3284allow the use of serial ports with programs with no inherent or broken 3285support for serial ports. Their use is deprecated, and they may be 3286removed from a future version of Linux. 3287 3288Arbitration of serial ports is provided by the use of lock files with 3289the names /var/lock/LCK..ttyX#. The contents of the lock file should 3290be the PID of the locking process as an ASCII number. 3291 3292It is common practice to install links such as /dev/modem 3293which point to serial ports. In order to ensure proper locking in the 3294presence of these links, it is recommended that software chase 3295symlinks and lock all possible names; additionally, it is recommended 3296that a lock file be installed with the corresponding alternate 3297device. In order to avoid deadlocks, it is recommended that the locks 3298are acquired in the following order, and released in the reverse: 3299 3300 1. The symbolic link name, if any (/var/lock/LCK..modem) 3301 2. The "tty" name (/var/lock/LCK..ttyS2) 3302 3. The alternate device name (/var/lock/LCK..cua2) 3303 3304In the case of nested symbolic links, the lock files should be 3305installed in the order the symlinks are resolved. 3306 3307Under no circumstances should an application hold a lock while waiting 3308for another to be released. In addition, applications which attempt 3309to create lock files for the corresponding alternate device names 3310should take into account the possibility of being used on a non-serial 3311port TTY, for which no alternate device would exist. 3312 3313 Pseudoterminals (PTYs) 3314 3315Pseudoterminals, or PTYs, are used to create login sessions or provide 3316other capabilities requiring a TTY line discipline (including SLIP or 3317PPP capability) to arbitrary data-generation processes. Each PTY has 3318a master side, named /dev/pty[p-za-e][0-9a-f], and a slave side, named 3319/dev/tty[p-za-e][0-9a-f]. The kernel arbitrates the use of PTYs by 3320allowing each master side to be opened only once. 3321 3322Once the master side has been opened, the corresponding slave device 3323can be used in the same manner as any TTY device. The master and 3324slave devices are connected by the kernel, generating the equivalent 3325of a bidirectional pipe with TTY capabilities. 3326 3327Recent versions of the Linux kernels and GNU libc contain support for 3328the System V/Unix98 naming scheme for PTYs, which assigns a common 3329device, /dev/ptmx, to all the masters (opening it will automatically 3330give you a previously unassigned PTY) and a subdirectory, /dev/pts, 3331for the slaves; the slaves are named with decimal integers (/dev/pts/# 3332in our notation). This removes the problem of exhausting the 3333namespace and enables the kernel to automatically create the device 3334nodes for the slaves on demand using the "devpts" filesystem. 3335 3336
