11 | as patches to the kernel maintainers (see the SubmittingPatches document). | |
12 | Specifically explore the sections titled "CHAR and MISC DRIVERS", and | |
13 | "BLOCK LAYER" in the MAINTAINERS file to find the right maintainers | |
14 | to involve for character and block devices. | |

31 | Linux now has extensive support for dynamic allocation of device numbering |
32 | and can use sysfs and udev (systemd) to handle the naming needs. There are | |
33 | still some exceptions in the serial and boot device area. Before asking | |
34 | for a device number make sure you actually need one. | |
1da177e4 | 35 | |
ebdf4040 LW |
36 | To have a major number allocated, or a minor number in situations |
37 | where that applies (e.g. busmice), please submit a patch and send to | |
38 | the authors as indicated above. | |
1da177e4 | 39 | |
ebdf4040 LW |
40 | Keep the description of the device *in the same format |
41 | as this list*. The reason for this is that it is the only way we have | |
42 | found to ensure we have all the requisite information to publish your | |
43 | device and avoid conflicts. | |
04c860c1 | 44 | |
ebdf4040 LW |
45 | Finally, sometimes we have to play "namespace police." Please don't be |
46 | offended. We often get submissions for /dev names that would be bound | |
47 | to cause conflicts down the road. We are trying to avoid getting in a | |
1da177e4 | 48 | situation where we would have to suffer an incompatible forward |
ebdf4040 | 49 | change. Therefore, please consult with us *before* you make your |
1da177e4 LT |
50 | device names and numbers in any way public, at least to the point |
51 | where it would be at all difficult to get them changed. | |

81 | Older kernels had /dev/ramdisk (1, 1) here. | |

91 | ||
92 | Pseudo-tty's are named as follows: | |
93 | * Masters are "pty", slaves are "tty"; | |
94 | * the fourth letter is one of pqrstuvwxyzabcde indicating | |
95 | the 1st through 16th series of 16 pseudo-ttys each, and | |
96 | * the fifth letter is one of 0123456789abcdef indicating | |
97 | the position within the series. | |

99 | These are the old-style (BSD) PTY devices; Unix98 | |
100 | devices are on major 128 and above and use the PTY | |
101 | master multiplex (/dev/ptmx) to acquire a PTY on | |
102 | demand. | |

3138 | **** ADDITIONAL /dev DIRECTORY ENTRIES |
3139 | ||
3140 | This section details additional entries that should or may exist in | |
3141 | the /dev directory. It is preferred that symbolic links use the same | |
3142 | form (absolute or relative) as is indicated here. Links are | |
3143 | classified as "hard" or "symbolic" depending on the preferred type of | |
3144 | link; if possible, the indicated type of link should be used. | |
3145 | ||
3146 | ||
3147 | Compulsory links | |
3148 | ||
3149 | These links should exist on all systems: | |
3150 | ||
3151 | /dev/fd /proc/self/fd symbolic File descriptors | |
3152 | /dev/stdin fd/0 symbolic stdin file descriptor | |
3153 | /dev/stdout fd/1 symbolic stdout file descriptor | |
3154 | /dev/stderr fd/2 symbolic stderr file descriptor | |
3155 | /dev/nfsd socksys symbolic Required by iBCS-2 | |
3156 | /dev/X0R null symbolic Required by iBCS-2 | |
3157 | ||
3158 | Note: /dev/X0R is <letter X>-<digit 0>-<letter R>. | |
3159 | ||
3160 | Recommended links | |
3161 | ||
3162 | It is recommended that these links exist on all systems: | |
3163 | ||
3164 | /dev/core /proc/kcore symbolic Backward compatibility | |
3165 | /dev/ramdisk ram0 symbolic Backward compatibility | |
3166 | /dev/ftape qft0 symbolic Backward compatibility | |
3167 | /dev/bttv0 video0 symbolic Backward compatibility | |
3168 | /dev/radio radio0 symbolic Backward compatibility | |
3169 | /dev/i2o* /dev/i2o/* symbolic Backward compatibility | |
3170 | /dev/scd? sr? hard Alternate SCSI CD-ROM name | |
3171 | ||
3172 | Locally defined links | |
3173 | ||
3174 | The following links may be established locally to conform to the | |
3175 | configuration of the system. This is merely a tabulation of existing | |
3176 | practice, and does not constitute a recommendation. However, if they | |
3177 | exist, they should have the following uses. | |
3178 | ||
3179 | /dev/mouse mouse port symbolic Current mouse device | |
3180 | /dev/tape tape device symbolic Current tape device | |
3181 | /dev/cdrom CD-ROM device symbolic Current CD-ROM device | |
3182 | /dev/cdwriter CD-writer symbolic Current CD-writer device | |
3183 | /dev/scanner scanner symbolic Current scanner device | |
3184 | /dev/modem modem port symbolic Current dialout device | |
3185 | /dev/root root device symbolic Current root filesystem | |
3186 | /dev/swap swap device symbolic Current swap device | |
3187 | ||
3188 | /dev/modem should not be used for a modem which supports dialin as | |
3189 | well as dialout, as it tends to cause lock file problems. If it | |
3190 | exists, /dev/modem should point to the appropriate primary TTY device | |
3191 | (the use of the alternate callout devices is deprecated). | |
3192 | ||
3193 | For SCSI devices, /dev/tape and /dev/cdrom should point to the | |
3194 | ``cooked'' devices (/dev/st* and /dev/sr*, respectively), whereas | |
3195 | /dev/cdwriter and /dev/scanner should point to the appropriate generic | |
3196 | SCSI devices (/dev/sg*). | |
3197 | ||
3198 | /dev/mouse may point to a primary serial TTY device, a hardware mouse | |
3199 | device, or a socket for a mouse driver program (e.g. /dev/gpmdata). | |
3200 | ||
3201 | Sockets and pipes | |
3202 | ||
3203 | Non-transient sockets and named pipes may exist in /dev. Common entries are: | |
3204 | ||
3205 | /dev/printer socket lpd local socket | |
3206 | /dev/log socket syslog local socket | |
3207 | /dev/gpmdata socket gpm mouse multiplexer | |
3208 | ||
3209 | Mount points | |
3210 | ||
3211 | The following names are reserved for mounting special filesystems | |
3212 | under /dev. These special filesystems provide kernel interfaces that | |
3213 | cannot be provided with standard device nodes. | |
3214 | ||
3215 | /dev/pts devpts PTY slave filesystem | |
3216 | /dev/shm tmpfs POSIX shared memory maintenance access | |
3217 | ||
3218 | **** TERMINAL DEVICES | |
3219 | ||
3220 | Terminal, or TTY devices are a special class of character devices. A | |
3221 | terminal device is any device that could act as a controlling terminal | |
3222 | for a session; this includes virtual consoles, serial ports, and | |
3223 | pseudoterminals (PTYs). | |
3224 | ||
3225 | All terminal devices share a common set of capabilities known as line | |
fff9289b | 3226 | disciplines; these include the common terminal line discipline as well |
1da177e4 LT |
3227 | as SLIP and PPP modes. |
3228 | ||
3229 | All terminal devices are named similarly; this section explains the | |
3230 | naming and use of the various types of TTYs. Note that the naming | |
3231 | conventions include several historical warts; some of these are | |
3232 | Linux-specific, some were inherited from other systems, and some | |
3233 | reflect Linux outgrowing a borrowed convention. | |
3234 | ||
3235 | A hash mark (#) in a device name is used here to indicate a decimal | |
3236 | number without leading zeroes. | |
3237 | ||
3238 | Virtual consoles and the console device | |
3239 | ||
3240 | Virtual consoles are full-screen terminal displays on the system video | |
3241 | monitor. Virtual consoles are named /dev/tty#, with numbering | |
3242 | starting at /dev/tty1; /dev/tty0 is the current virtual console. | |
3243 | /dev/tty0 is the device that should be used to access the system video | |
3244 | card on those architectures for which the frame buffer devices | |
3245 | (/dev/fb*) are not applicable. Do not use /dev/console | |
3246 | for this purpose. | |
3247 | ||
3248 | The console device, /dev/console, is the device to which system | |
3249 | messages should be sent, and on which logins should be permitted in | |
3250 | single-user mode. Starting with Linux 2.1.71, /dev/console is managed | |
3251 | by the kernel; for previous versions it should be a symbolic link to | |
3252 | either /dev/tty0, a specific virtual console such as /dev/tty1, or to | |
3253 | a serial port primary (tty*, not cu*) device, depending on the | |
3254 | configuration of the system. | |
3255 | ||
3256 | Serial ports | |
3257 | ||
3258 | Serial ports are RS-232 serial ports and any device which simulates | |
3259 | one, either in hardware (such as internal modems) or in software (such | |
3260 | as the ISDN driver.) Under Linux, each serial ports has two device | |
3261 | names, the primary or callin device and the alternate or callout one. | |
3262 | Each kind of device is indicated by a different letter. For any | |
3263 | letter X, the names of the devices are /dev/ttyX# and /dev/cux#, | |
3264 | respectively; for historical reasons, /dev/ttyS# and /dev/ttyC# | |
3265 | correspond to /dev/cua# and /dev/cub#. In the future, it should be | |
3266 | expected that multiple letters will be used; all letters will be upper | |
3267 | case for the "tty" device (e.g. /dev/ttyDP#) and lower case for the | |
3268 | "cu" device (e.g. /dev/cudp#). | |
3269 | ||
3270 | The names /dev/ttyQ# and /dev/cuq# are reserved for local use. | |
3271 | ||
3272 | The alternate devices provide for kernel-based exclusion and somewhat | |
3273 | different defaults than the primary devices. Their main purpose is to | |
3274 | allow the use of serial ports with programs with no inherent or broken | |
3275 | support for serial ports. Their use is deprecated, and they may be | |
3276 | removed from a future version of Linux. | |
3277 | ||
3278 | Arbitration of serial ports is provided by the use of lock files with | |
3279 | the names /var/lock/LCK..ttyX#. The contents of the lock file should | |
3280 | be the PID of the locking process as an ASCII number. | |
3281 | ||
3282 | It is common practice to install links such as /dev/modem | |
3283 | which point to serial ports. In order to ensure proper locking in the | |
3284 | presence of these links, it is recommended that software chase | |
3285 | symlinks and lock all possible names; additionally, it is recommended | |
3286 | that a lock file be installed with the corresponding alternate | |
3287 | device. In order to avoid deadlocks, it is recommended that the locks | |
3288 | are acquired in the following order, and released in the reverse: | |
3289 | ||
3290 | 1. The symbolic link name, if any (/var/lock/LCK..modem) | |
3291 | 2. The "tty" name (/var/lock/LCK..ttyS2) | |
3292 | 3. The alternate device name (/var/lock/LCK..cua2) | |
3293 | ||
3294 | In the case of nested symbolic links, the lock files should be | |
3295 | installed in the order the symlinks are resolved. | |
3296 | ||
3297 | Under no circumstances should an application hold a lock while waiting | |
3298 | for another to be released. In addition, applications which attempt | |
3299 | to create lock files for the corresponding alternate device names | |
3300 | should take into account the possibility of being used on a non-serial | |
3301 | port TTY, for which no alternate device would exist. | |
3302 | ||
3303 | Pseudoterminals (PTYs) | |
3304 | ||
3305 | Pseudoterminals, or PTYs, are used to create login sessions or provide | |
fff9289b | 3306 | other capabilities requiring a TTY line discipline (including SLIP or |
1da177e4 LT |
3307 | PPP capability) to arbitrary data-generation processes. Each PTY has |
3308 | a master side, named /dev/pty[p-za-e][0-9a-f], and a slave side, named | |
3309 | /dev/tty[p-za-e][0-9a-f]. The kernel arbitrates the use of PTYs by | |
3310 | allowing each master side to be opened only once. | |
3311 | ||
3312 | Once the master side has been opened, the corresponding slave device | |
3313 | can be used in the same manner as any TTY device. The master and | |
3314 | slave devices are connected by the kernel, generating the equivalent | |
3315 | of a bidirectional pipe with TTY capabilities. | |
3316 | ||
3317 | Recent versions of the Linux kernels and GNU libc contain support for | |
3318 | the System V/Unix98 naming scheme for PTYs, which assigns a common | |
3319 | device, /dev/ptmx, to all the masters (opening it will automatically | |
3320 | give you a previously unassigned PTY) and a subdirectory, /dev/pts, | |
3321 | for the slaves; the slaves are named with decimal integers (/dev/pts/# | |
3322 | in our notation). This removes the problem of exhausting the | |
3323 | namespace and enables the kernel to automatically create the device | |
3324 | nodes for the slaves on demand using the "devpts" filesystem. | |
3325 |
