8 | This list is the Linux Device List, the official registry of allocated | |
9 | device numbers and /dev directory nodes for the Linux operating | |
10 | system. | |
11 | ||
12 | The latest version of this list is available from | |
13 | http://www.lanana.org/docs/device-list/ or | |
14 | ftp://ftp.kernel.org/pub/linux/docs/device-list/. This version may be | |
15 | newer than the one distributed with the Linux kernel. | |
16 | ||
17 | The LaTeX version of this document is no longer maintained. | |
18 | ||
19 | This document is included by reference into the Filesystem Hierarchy | |
20 | Standard (FHS). The FHS is available from http://www.pathname.com/fhs/. | |
21 | ||
22 | Allocations marked (68k/Amiga) apply to Linux/68k on the Amiga | |
23 | platform only. Allocations marked (68k/Atari) apply to Linux/68k on | |
24 | the Atari platform only. | |
25 | ||
26 | The symbol {2.6} means the allocation is obsolete and scheduled for | |
27 | removal once kernel version 2.6 (or equivalent) is released. Some of these | |
28 | allocations have already been removed. | |
29 | ||
30 | This document is in the public domain. The author requests, however, | |
31 | that semantically altered versions are not distributed without | |
32 | permission of the author, assuming the author can be contacted without | |
33 | an unreasonable effort. | |
34 | ||
35 | In particular, please don't sent patches for this list to Linus, at | |
36 | least not without contacting me first. | |
37 | ||
38 | I do not have any information about these devices beyond what appears | |
39 | on this list. Any such information requests will be deleted without | |
40 | reply. | |
41 | ||
42 | ||
43 | **** DEVICE DRIVERS AUTHORS PLEASE READ THIS **** | |
44 | ||
45 | To have a major number allocated, or a minor number in situations | |
46 | where that applies (e.g. busmice), please contact me with the | |
47 | appropriate device information. Also, if you have additional | |
48 | information regarding any of the devices listed below, or if I have | |
49 | made a mistake, I would greatly appreciate a note. | |
50 | ||
51 | I do, however, make a few requests about the nature of your report. | |
52 | This is necessary for me to be able to keep this list up to date and | |
53 | correct in a timely manner. First of all, *please* send it to the | |
54 | correct address... <device@lanana.org>. I receive hundreds of email | |
55 | messages a day, so mail sent to other addresses may very well get lost | |
56 | in the avalanche. Please put in a descriptive subject, so I can find | |
57 | your mail again should I need to. Too many people send me email | |
58 | saying just "device number request" in the subject. | |
59 | ||
60 | Second, please include a description of the device *in the same format | |
61 | as this list*. The reason for this is that it is the only way I have | |
62 | found to ensure I have all the requisite information to publish your | |
63 | device and avoid conflicts. | |
64 | ||
65 | Third, please don't assume that the distributed version of the list is | |
66 | up to date. Due to the number of registrations I have to maintain it | |
67 | in "batch mode", so there is likely additional registrations that | |
68 | haven't been listed yet. | |
69 | ||

70 | Fourth, remember that Linux now has extensive support for dynamic allocation |
71 | of device numbering and can use sysfs and udev to handle the naming needs. | |
72 | There are still some exceptions in the serial and boot device area. Before | |
73 | asking for a device number make sure you actually need one. | |
74 | ||
1da177e4 LT |
75 | Finally, sometimes I have to play "namespace police." Please don't be |
76 | offended. I often get submissions for /dev names that would be bound | |
77 | to cause conflicts down the road. I am trying to avoid getting in a | |
78 | situation where we would have to suffer an incompatible forward | |
79 | change. Therefore, please consult with me *before* you make your | |
80 | device names and numbers in any way public, at least to the point | |
81 | where it would be at all difficult to get them changed. | |
82 | ||
83 | Your cooperation is appreciated. | |

86 | 0 Unnamed devices (e.g. non-device mounts) | |
87 | 0 = reserved as null device number | |

108 | ... | |
04c860c1 | 109 | 250 = /dev/initrd Initial RAM disk |
1da177e4 LT |
110 | |
111 | Older kernels had /dev/ramdisk (1, 1) here. | |
112 | /dev/initrd refers to a RAM disk which was preloaded | |
113 | by the boot loader; newer kernels use /dev/ram0 for | |
114 | the initrd. | |
115 | ||
116 | 2 char Pseudo-TTY masters | |
117 | 0 = /dev/ptyp0 First PTY master | |
118 | 1 = /dev/ptyp1 Second PTY master | |
119 | ... | |
120 | 255 = /dev/ptyef 256th PTY master | |
121 | ||
122 | Pseudo-tty's are named as follows: | |
123 | * Masters are "pty", slaves are "tty"; | |
124 | * the fourth letter is one of pqrstuvwxyzabcde indicating | |
125 | the 1st through 16th series of 16 pseudo-ttys each, and | |
126 | * the fifth letter is one of 0123456789abcdef indicating | |
127 | the position within the series. | |
128 | ||
129 | These are the old-style (BSD) PTY devices; Unix98 | |
130 | devices are on major 128 and above and use the PTY | |
131 | master multiplex (/dev/ptmx) to acquire a PTY on | |
132 | demand. | |

183 | ||
184 | NOTE: The letter in the device name (d, q, h or u) | |
185 | signifies the type of drive: 5.25" Double Density (d), | |
186 | 5.25" Quad Density (q), 5.25" High Density (h) or 3.5" | |
187 | (any model, u). The use of the capital letters D, H | |
188 | and E for the 3.5" models have been deprecated, since | |
189 | the drive type is insignificant for these devices. | |

201 | 0 = /dev/hda Master: whole disk (or CD-ROM) | |
202 | 64 = /dev/hdb Slave: whole disk (or CD-ROM) | |
203 | ||
204 | For partitions, add to the whole disk device number: | |
205 | 0 = /dev/hd? Whole disk | |
206 | 1 = /dev/hd?1 First partition | |
207 | 2 = /dev/hd?2 Second partition | |
208 | ... | |
209 | 63 = /dev/hd?63 63rd partition | |
210 | ||
211 | For Linux/i386, partitions 1-4 are the primary | |
212 | partitions, and 5 and above are logical partitions. | |
213 | Other versions of Linux use partitioning schemes | |
214 | appropriate to their respective architectures. | |

225 | ||
226 | UART serial ports refer to 8250/16450/16550 series devices. | |
227 | ||
228 | Older versions of the Linux kernel used this major | |
229 | number for BSD PTY devices. As of Linux 2.1.115, this | |
230 | is no longer supported. Use major numbers 2 and 3. | |

317 | "No rewind" refers to the omission of the default | |
318 | automatic rewind on device close. The MTREW or MTOFFL | |
319 | ioctl()'s can be used to rewind the tape regardless of | |

3154 | **** ADDITIONAL /dev DIRECTORY ENTRIES |
3155 | ||
3156 | This section details additional entries that should or may exist in | |
3157 | the /dev directory. It is preferred that symbolic links use the same | |
3158 | form (absolute or relative) as is indicated here. Links are | |
3159 | classified as "hard" or "symbolic" depending on the preferred type of | |
3160 | link; if possible, the indicated type of link should be used. | |
3161 | ||
3162 | ||
3163 | Compulsory links | |
3164 | ||
3165 | These links should exist on all systems: | |
3166 | ||
3167 | /dev/fd /proc/self/fd symbolic File descriptors | |
3168 | /dev/stdin fd/0 symbolic stdin file descriptor | |
3169 | /dev/stdout fd/1 symbolic stdout file descriptor | |
3170 | /dev/stderr fd/2 symbolic stderr file descriptor | |
3171 | /dev/nfsd socksys symbolic Required by iBCS-2 | |
3172 | /dev/X0R null symbolic Required by iBCS-2 | |
3173 | ||
3174 | Note: /dev/X0R is <letter X>-<digit 0>-<letter R>. | |
3175 | ||
3176 | Recommended links | |
3177 | ||
3178 | It is recommended that these links exist on all systems: | |
3179 | ||
3180 | /dev/core /proc/kcore symbolic Backward compatibility | |
3181 | /dev/ramdisk ram0 symbolic Backward compatibility | |
3182 | /dev/ftape qft0 symbolic Backward compatibility | |
3183 | /dev/bttv0 video0 symbolic Backward compatibility | |
3184 | /dev/radio radio0 symbolic Backward compatibility | |
3185 | /dev/i2o* /dev/i2o/* symbolic Backward compatibility | |
3186 | /dev/scd? sr? hard Alternate SCSI CD-ROM name | |
3187 | ||
3188 | Locally defined links | |
3189 | ||
3190 | The following links may be established locally to conform to the | |
3191 | configuration of the system. This is merely a tabulation of existing | |
3192 | practice, and does not constitute a recommendation. However, if they | |
3193 | exist, they should have the following uses. | |
3194 | ||
3195 | /dev/mouse mouse port symbolic Current mouse device | |
3196 | /dev/tape tape device symbolic Current tape device | |
3197 | /dev/cdrom CD-ROM device symbolic Current CD-ROM device | |
3198 | /dev/cdwriter CD-writer symbolic Current CD-writer device | |
3199 | /dev/scanner scanner symbolic Current scanner device | |
3200 | /dev/modem modem port symbolic Current dialout device | |
3201 | /dev/root root device symbolic Current root filesystem | |
3202 | /dev/swap swap device symbolic Current swap device | |
3203 | ||
3204 | /dev/modem should not be used for a modem which supports dialin as | |
3205 | well as dialout, as it tends to cause lock file problems. If it | |
3206 | exists, /dev/modem should point to the appropriate primary TTY device | |
3207 | (the use of the alternate callout devices is deprecated). | |
3208 | ||
3209 | For SCSI devices, /dev/tape and /dev/cdrom should point to the | |
3210 | ``cooked'' devices (/dev/st* and /dev/sr*, respectively), whereas | |
3211 | /dev/cdwriter and /dev/scanner should point to the appropriate generic | |
3212 | SCSI devices (/dev/sg*). | |
3213 | ||
3214 | /dev/mouse may point to a primary serial TTY device, a hardware mouse | |
3215 | device, or a socket for a mouse driver program (e.g. /dev/gpmdata). | |
3216 | ||
3217 | Sockets and pipes | |
3218 | ||
3219 | Non-transient sockets and named pipes may exist in /dev. Common entries are: | |
3220 | ||
3221 | /dev/printer socket lpd local socket | |
3222 | /dev/log socket syslog local socket | |
3223 | /dev/gpmdata socket gpm mouse multiplexer | |
3224 | ||
3225 | Mount points | |
3226 | ||
3227 | The following names are reserved for mounting special filesystems | |
3228 | under /dev. These special filesystems provide kernel interfaces that | |
3229 | cannot be provided with standard device nodes. | |
3230 | ||
3231 | /dev/pts devpts PTY slave filesystem | |
3232 | /dev/shm tmpfs POSIX shared memory maintenance access | |
3233 | ||
3234 | **** TERMINAL DEVICES | |
3235 | ||
3236 | Terminal, or TTY devices are a special class of character devices. A | |
3237 | terminal device is any device that could act as a controlling terminal | |
3238 | for a session; this includes virtual consoles, serial ports, and | |
3239 | pseudoterminals (PTYs). | |
3240 | ||
3241 | All terminal devices share a common set of capabilities known as line | |
fff9289b | 3242 | disciplines; these include the common terminal line discipline as well |
1da177e4 LT |
3243 | as SLIP and PPP modes. |
3244 | ||
3245 | All terminal devices are named similarly; this section explains the | |
3246 | naming and use of the various types of TTYs. Note that the naming | |
3247 | conventions include several historical warts; some of these are | |
3248 | Linux-specific, some were inherited from other systems, and some | |
3249 | reflect Linux outgrowing a borrowed convention. | |
3250 | ||
3251 | A hash mark (#) in a device name is used here to indicate a decimal | |
3252 | number without leading zeroes. | |
3253 | ||
3254 | Virtual consoles and the console device | |
3255 | ||
3256 | Virtual consoles are full-screen terminal displays on the system video | |
3257 | monitor. Virtual consoles are named /dev/tty#, with numbering | |
3258 | starting at /dev/tty1; /dev/tty0 is the current virtual console. | |
3259 | /dev/tty0 is the device that should be used to access the system video | |
3260 | card on those architectures for which the frame buffer devices | |
3261 | (/dev/fb*) are not applicable. Do not use /dev/console | |
3262 | for this purpose. | |
3263 | ||
3264 | The console device, /dev/console, is the device to which system | |
3265 | messages should be sent, and on which logins should be permitted in | |
3266 | single-user mode. Starting with Linux 2.1.71, /dev/console is managed | |
3267 | by the kernel; for previous versions it should be a symbolic link to | |
3268 | either /dev/tty0, a specific virtual console such as /dev/tty1, or to | |
3269 | a serial port primary (tty*, not cu*) device, depending on the | |
3270 | configuration of the system. | |
3271 | ||
3272 | Serial ports | |
3273 | ||
3274 | Serial ports are RS-232 serial ports and any device which simulates | |
3275 | one, either in hardware (such as internal modems) or in software (such | |
3276 | as the ISDN driver.) Under Linux, each serial ports has two device | |
3277 | names, the primary or callin device and the alternate or callout one. | |
3278 | Each kind of device is indicated by a different letter. For any | |
3279 | letter X, the names of the devices are /dev/ttyX# and /dev/cux#, | |
3280 | respectively; for historical reasons, /dev/ttyS# and /dev/ttyC# | |
3281 | correspond to /dev/cua# and /dev/cub#. In the future, it should be | |
3282 | expected that multiple letters will be used; all letters will be upper | |
3283 | case for the "tty" device (e.g. /dev/ttyDP#) and lower case for the | |
3284 | "cu" device (e.g. /dev/cudp#). | |
3285 | ||
3286 | The names /dev/ttyQ# and /dev/cuq# are reserved for local use. | |
3287 | ||
3288 | The alternate devices provide for kernel-based exclusion and somewhat | |
3289 | different defaults than the primary devices. Their main purpose is to | |
3290 | allow the use of serial ports with programs with no inherent or broken | |
3291 | support for serial ports. Their use is deprecated, and they may be | |
3292 | removed from a future version of Linux. | |
3293 | ||
3294 | Arbitration of serial ports is provided by the use of lock files with | |
3295 | the names /var/lock/LCK..ttyX#. The contents of the lock file should | |
3296 | be the PID of the locking process as an ASCII number. | |
3297 | ||
3298 | It is common practice to install links such as /dev/modem | |
3299 | which point to serial ports. In order to ensure proper locking in the | |
3300 | presence of these links, it is recommended that software chase | |
3301 | symlinks and lock all possible names; additionally, it is recommended | |
3302 | that a lock file be installed with the corresponding alternate | |
3303 | device. In order to avoid deadlocks, it is recommended that the locks | |
3304 | are acquired in the following order, and released in the reverse: | |
3305 | ||
3306 | 1. The symbolic link name, if any (/var/lock/LCK..modem) | |
3307 | 2. The "tty" name (/var/lock/LCK..ttyS2) | |
3308 | 3. The alternate device name (/var/lock/LCK..cua2) | |
3309 | ||
3310 | In the case of nested symbolic links, the lock files should be | |
3311 | installed in the order the symlinks are resolved. | |
3312 | ||
3313 | Under no circumstances should an application hold a lock while waiting | |
3314 | for another to be released. In addition, applications which attempt | |
3315 | to create lock files for the corresponding alternate device names | |
3316 | should take into account the possibility of being used on a non-serial | |
3317 | port TTY, for which no alternate device would exist. | |
3318 | ||
3319 | Pseudoterminals (PTYs) | |
3320 | ||
3321 | Pseudoterminals, or PTYs, are used to create login sessions or provide | |
fff9289b | 3322 | other capabilities requiring a TTY line discipline (including SLIP or |
1da177e4 LT |
3323 | PPP capability) to arbitrary data-generation processes. Each PTY has |
3324 | a master side, named /dev/pty[p-za-e][0-9a-f], and a slave side, named | |
3325 | /dev/tty[p-za-e][0-9a-f]. The kernel arbitrates the use of PTYs by | |
3326 | allowing each master side to be opened only once. | |
3327 | ||
3328 | Once the master side has been opened, the corresponding slave device | |
3329 | can be used in the same manner as any TTY device. The master and | |
3330 | slave devices are connected by the kernel, generating the equivalent | |
3331 | of a bidirectional pipe with TTY capabilities. | |
3332 | ||
3333 | Recent versions of the Linux kernels and GNU libc contain support for | |
3334 | the System V/Unix98 naming scheme for PTYs, which assigns a common | |
3335 | device, /dev/ptmx, to all the masters (opening it will automatically | |
3336 | give you a previously unassigned PTY) and a subdirectory, /dev/pts, | |
3337 | for the slaves; the slaves are named with decimal integers (/dev/pts/# | |
3338 | in our notation). This removes the problem of exhausting the | |
3339 | namespace and enables the kernel to automatically create the device | |
3340 | nodes for the slaves on demand using the "devpts" filesystem. | |
3341 |
