29 | **** DEVICE DRIVERS AUTHORS PLEASE READ THIS **** |
30 | |
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. |
35 | |
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. |
39 | |
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. |
44 | |
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 |
48 | situation where we would have to suffer an incompatible forward |
49 | change. Therefore, please consult with us *before* you make your |
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. |
52 | |
53 | Your cooperation is appreciated. |
54 | |
55 | |
56 | 0 Unnamed devices (e.g. non-device mounts) |
57 | 0 = reserved as null device number |
58 | See block major 144, 145, 146 for expansion areas. |
59 | |
60 | 1 char Memory devices |
61 | 1 = /dev/mem Physical memory access |
62 | 2 = /dev/kmem Kernel virtual memory access |
63 | 3 = /dev/null Null device |
64 | 4 = /dev/port I/O port access |
65 | 5 = /dev/zero Null byte source |
66 | 6 = /dev/core OBSOLETE - replaced by /proc/kcore |
67 | 7 = /dev/full Returns ENOSPC on write |
68 | 8 = /dev/random Nondeterministic random number gen. |
69 | 9 = /dev/urandom Faster, less secure random number gen. |
70 | 10 = /dev/aio Asynchronous I/O notification interface |
71 | 11 = /dev/kmsg Writes to this come out as printk's, reads |
72 | export the buffered printk records. |
73 | 12 = /dev/oldmem OBSOLETE - replaced by /proc/vmcore |
74 | |
75 | 1 block RAM disk |
76 | 0 = /dev/ram0 First RAM disk |
77 | 1 = /dev/ram1 Second RAM disk |
78 | ... |
79 | 250 = /dev/initrd Initial RAM disk |
80 | |
81 | Older kernels had /dev/ramdisk (1, 1) here. |
82 | /dev/initrd refers to a RAM disk which was preloaded |
83 | by the boot loader; newer kernels use /dev/ram0 for |
84 | the initrd. |
85 | |
86 | 2 char Pseudo-TTY masters |
87 | 0 = /dev/ptyp0 First PTY master |
88 | 1 = /dev/ptyp1 Second PTY master |
89 | ... |
90 | 255 = /dev/ptyef 256th PTY master |
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. |
98 | |
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. |
103 | |
104 | 2 block Floppy disks |
105 | 0 = /dev/fd0 Controller 0, drive 0, autodetect |

147 | |
148 | 36 = /dev/fd?CompaQ Compaq 2880K drive; obsolete? |
149 | |
150 | (1) Autodetectable format |
151 | (2) Autodetectable format in a Double Density (720K) drive only |
152 | (3) Autodetectable format in a High Density (1440K) drive only |
153 | |
154 | NOTE: The letter in the device name (d, q, h or u) |
155 | signifies the type of drive: 5.25" Double Density (d), |
156 | 5.25" Quad Density (q), 5.25" High Density (h) or 3.5" |
157 | (any model, u). The use of the capital letters D, H |
158 | and E for the 3.5" models have been deprecated, since |
159 | the drive type is insignificant for these devices. |
160 | |
161 | 3 char Pseudo-TTY slaves |
162 | 0 = /dev/ttyp0 First PTY slave |
163 | 1 = /dev/ttyp1 Second PTY slave |
164 | ... |
165 | 255 = /dev/ttyef 256th PTY slave |
166 | |
167 | These are the old-style (BSD) PTY devices; Unix98 |
168 | devices are on major 136 and above. |
169 | |
170 | 3 block First MFM, RLL and IDE hard disk/CD-ROM interface |
171 | 0 = /dev/hda Master: whole disk (or CD-ROM) |
172 | 64 = /dev/hdb Slave: whole disk (or CD-ROM) |
173 | |
174 | For partitions, add to the whole disk device number: |
175 | 0 = /dev/hd? Whole disk |
176 | 1 = /dev/hd?1 First partition |
177 | 2 = /dev/hd?2 Second partition |
178 | ... |
179 | 63 = /dev/hd?63 63rd partition |
180 | |
181 | For Linux/i386, partitions 1-4 are the primary |
182 | partitions, and 5 and above are logical partitions. |
183 | Other versions of Linux use partitioning schemes |
184 | appropriate to their respective architectures. |
185 | |
186 | 4 char TTY devices |
187 | 0 = /dev/tty0 Current virtual console |
188 | |
189 | 1 = /dev/tty1 First virtual console |
190 | ... |
191 | 63 = /dev/tty63 63rd virtual console |
192 | 64 = /dev/ttyS0 First UART serial port |
193 | ... |
194 | 255 = /dev/ttyS191 192nd UART serial port |
195 | |
196 | UART serial ports refer to 8250/16450/16550 series devices. |
197 | |
198 | Older versions of the Linux kernel used this major |
199 | number for BSD PTY devices. As of Linux 2.1.115, this |
200 | is no longer supported. Use major numbers 2 and 3. |
201 | |
202 | 4 block Aliases for dynamically allocated major devices to be used |
203 | when its not possible to create the real device nodes |
204 | because the root filesystem is mounted read-only. |
205 | |
206 | 0 = /dev/root |
207 | |
208 | 5 char Alternate TTY devices |
209 | 0 = /dev/tty Current TTY device |
210 | 1 = /dev/console System console |
211 | 2 = /dev/ptmx PTY master multiplex |
212 | 3 = /dev/ttyprintk User messages via printk TTY device |
213 | 64 = /dev/cua0 Callout device for ttyS0 |
214 | ... |
215 | 255 = /dev/cua191 Callout device for ttyS191 |
216 | |
217 | (5,1) is /dev/console starting with Linux 2.1.71. See |
218 | the section on terminal devices for more information |
219 | on /dev/console. |
220 | |
221 | 6 char Parallel printer devices |
222 | 0 = /dev/lp0 Parallel printer on parport0 |
223 | 1 = /dev/lp1 Parallel printer on parport1 |
224 | ... |
225 | |
226 | Current Linux kernels no longer have a fixed mapping |
227 | between parallel ports and I/O addresses. Instead, |
228 | they are redirected through the parport multiplex layer. |
229 | |
230 | 7 char Virtual console capture devices |
231 | 0 = /dev/vcs Current vc text contents |
232 | 1 = /dev/vcs1 tty1 text contents |
233 | ... |
234 | 63 = /dev/vcs63 tty63 text contents |
235 | 128 = /dev/vcsa Current vc text/attribute contents |
236 | 129 = /dev/vcsa1 tty1 text/attribute contents |
237 | ... |
238 | 191 = /dev/vcsa63 tty63 text/attribute contents |
239 | |
240 | NOTE: These devices permit both read and write access. |
241 | |
242 | 7 block Loopback devices |
243 | 0 = /dev/loop0 First loop device |
244 | 1 = /dev/loop1 Second loop device |
245 | ... |
246 | |
247 | The loop devices are used to mount filesystems not |
248 | associated with block devices. The binding to the |
249 | loop devices is handled by mount(8) or losetup(8). |
250 | |
251 | 8 block SCSI disk devices (0-15) |
252 | 0 = /dev/sda First SCSI disk whole disk |
253 | 16 = /dev/sdb Second SCSI disk whole disk |
254 | 32 = /dev/sdc Third SCSI disk whole disk |
255 | ... |
256 | 240 = /dev/sdp Sixteenth SCSI disk whole disk |
257 | |
258 | Partitions are handled in the same way as for IDE |
259 | disks (see major number 3) except that the limit on |
260 | partitions is 15. |
261 | |
262 | 9 char SCSI tape devices |
263 | 0 = /dev/st0 First SCSI tape, mode 0 |
264 | 1 = /dev/st1 Second SCSI tape, mode 0 |
265 | ... |
266 | 32 = /dev/st0l First SCSI tape, mode 1 |

269 | 64 = /dev/st0m First SCSI tape, mode 2 |
270 | 65 = /dev/st1m Second SCSI tape, mode 2 |
271 | ... |
272 | 96 = /dev/st0a First SCSI tape, mode 3 |
273 | 97 = /dev/st1a Second SCSI tape, mode 3 |
274 | ... |
275 | 128 = /dev/nst0 First SCSI tape, mode 0, no rewind |
276 | 129 = /dev/nst1 Second SCSI tape, mode 0, no rewind |
277 | ... |
278 | 160 = /dev/nst0l First SCSI tape, mode 1, no rewind |
279 | 161 = /dev/nst1l Second SCSI tape, mode 1, no rewind |
280 | ... |
281 | 192 = /dev/nst0m First SCSI tape, mode 2, no rewind |
282 | 193 = /dev/nst1m Second SCSI tape, mode 2, no rewind |
283 | ... |
284 | 224 = /dev/nst0a First SCSI tape, mode 3, no rewind |
285 | 225 = /dev/nst1a Second SCSI tape, mode 3, no rewind |
286 | ... |
287 | |
288 | "No rewind" refers to the omission of the default |
289 | automatic rewind on device close. The MTREW or MTOFFL |
290 | ioctl()'s can be used to rewind the tape regardless of |
291 | the device used to access it. |
292 | |
293 | 9 block Metadisk (RAID) devices |
294 | 0 = /dev/md0 First metadisk group |
295 | 1 = /dev/md1 Second metadisk group |
296 | ... |
297 | |
298 | The metadisk driver is used to span a |
299 | filesystem across multiple physical disks. |

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 |
3226 | disciplines; these include the common terminal line discipline as well |
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 |
3306 | other capabilities requiring a TTY line discipline (including SLIP or |
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 | |
3326 |
