2 LINUX ALLOCATED DEVICES
3 Maintained by H. Peter Anvin <device@lanana.org>

7 This list is the Linux Device List, the official registry of allocated
8 device numbers and /dev directory nodes for the Linux operating
11 The latest version of this list is available from
12 http://www.lanana.org/docs/device-list/ or
13 ftp://ftp.kernel.org/pub/linux/docs/device-list/. This version may be
14 newer than the one distributed with the Linux kernel.
16 The LaTeX version of this document is no longer maintained.
18 This document is included by reference into the Filesystem Hierarchy
19 Standard (FHS). The FHS is available from http://www.pathname.com/fhs/.
21 Allocations marked (68k/Amiga) apply to Linux/68k on the Amiga
22 platform only. Allocations marked (68k/Atari) apply to Linux/68k on
23 the Atari platform only.
25 The symbol {2.6} means the allocation is obsolete and scheduled for
26 removal once kernel version 2.6 (or equivalent) is released.
28 This document is in the public domain. The author requests, however,
29 that semantically altered versions are not distributed without
30 permission of the author, assuming the author can be contacted without
31 an unreasonable effort.
33 In particular, please don't sent patches for this list to Linus, at
34 least not without contacting me first.
36 I do not have any information about these devices beyond what appears
37 on this list. Any such information requests will be deleted without
41 **** DEVICE DRIVERS AUTHORS PLEASE READ THIS ****
43 THE DEVICE REGISTRY IS OFFICIALLY FROZEN FOR LINUS TORVALDS' KERNEL
44 TREE. At Linus' request, no more allocations will be made official
45 for Linus' kernel tree; the 3 June 2001 version of this list is the
46 official final version of this registry. At Alan Cox' request,
47 however, the registry will continue to be maintained for the -ac
48 series of kernels, and registrations will be accepted.
50 To have a major number allocated, or a minor number in situations
51 where that applies (e.g. busmice), please contact me with the
52 appropriate device information. Also, if you have additional
53 information regarding any of the devices listed below, or if I have
54 made a mistake, I would greatly appreciate a note.
56 I do, however, make a few requests about the nature of your report.
57 This is necessary for me to be able to keep this list up to date and
58 correct in a timely manner. First of all, *please* send it to the
59 correct address... <device@lanana.org>. I receive hundreds of email
60 messages a day, so mail sent to other addresses may very well get lost
61 in the avalanche. Please put in a descriptive subject, so I can find
62 your mail again should I need to. Too many people send me email
63 saying just "device number request" in the subject.
65 Second, please include a description of the device *in the same format
66 as this list*. The reason for this is that it is the only way I have
67 found to ensure I have all the requisite information to publish your
68 device and avoid conflicts.
70 Third, please don't assume that the distributed version of the list is
71 up to date. Due to the number of registrations I have to maintain it
72 in "batch mode", so there is likely additional registrations that
73 haven't been listed yet.
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.
83 Your cooperation is appreciated.
86 0 Unnamed devices (e.g. non-device mounts)
87 0 = reserved as null device number

108 by the boot loader; newer kernels use /dev/ram0 for
111 2 char Pseudo-TTY masters
112 0 = /dev/ptyp0 First PTY master
113 1 = /dev/ptyp1 Second PTY master
115 255 = /dev/ptyef 256th PTY master
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.
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

175 (1) Autodetectable format
176 (2) Autodetectable format in a Double Density (720K) drive only
177 (3) Autodetectable format in a High Density (1440K) drive only
179 NOTE: The letter in the device name (d, q, h or u)
180 signifies the type of drive: 5.25" Double Density (d),
181 5.25" Quad Density (q), 5.25" High Density (h) or 3.5"
182 (any model, u). The use of the capital letters D, H
183 and E for the 3.5" models have been deprecated, since
184 the drive type is insignificant for these devices.
186 3 char Pseudo-TTY slaves
187 0 = /dev/ttyp0 First PTY slave
188 1 = /dev/ttyp1 Second PTY slave
190 255 = /dev/ttyef 256th PTY slave
192 These are the old-style (BSD) PTY devices; Unix98
193 devices are on major 136 and above.
195 block First MFM, RLL and IDE hard disk/CD-ROM interface
196 0 = /dev/hda Master: whole disk (or CD-ROM)
197 64 = /dev/hdb Slave: whole disk (or CD-ROM)
199 For partitions, add to the whole disk device number:
200 0 = /dev/hd? Whole disk
201 1 = /dev/hd?1 First partition
202 2 = /dev/hd?2 Second partition
204 63 = /dev/hd?63 63rd partition
206 For Linux/i386, partitions 1-4 are the primary
207 partitions, and 5 and above are logical partitions.
208 Other versions of Linux use partitioning schemes
209 appropriate to their respective architectures.
212 0 = /dev/tty0 Current virtual console
214 1 = /dev/tty1 First virtual console
216 63 = /dev/tty63 63rd virtual console
217 64 = /dev/ttyS0 First UART serial port
219 255 = /dev/ttyS191 192nd UART serial port
221 UART serial ports refer to 8250/16450/16550 series devices.
223 Older versions of the Linux kernel used this major
224 number for BSD PTY devices. As of Linux 2.1.115, this
225 is no longer supported. Use major numbers 2 and 3.
227 5 char Alternate TTY devices
228 0 = /dev/tty Current TTY device
229 1 = /dev/console System console
230 2 = /dev/ptmx PTY master multiplex
231 64 = /dev/cua0 Callout device for ttyS0
233 255 = /dev/cua191 Callout device for ttyS191
235 (5,1) is /dev/console starting with Linux 2.1.71. See
236 the section on terminal devices for more information
239 6 char Parallel printer devices
240 0 = /dev/lp0 Parallel printer on parport0
241 1 = /dev/lp1 Parallel printer on parport1
244 Current Linux kernels no longer have a fixed mapping
245 between parallel ports and I/O addresses. Instead,
246 they are redirected through the parport multiplex layer.
248 7 char Virtual console capture devices
249 0 = /dev/vcs Current vc text contents
250 1 = /dev/vcs1 tty1 text contents
252 63 = /dev/vcs63 tty63 text contents
253 128 = /dev/vcsa Current vc text/attribute contents
254 129 = /dev/vcsa1 tty1 text/attribute contents
256 191 = /dev/vcsa63 tty63 text/attribute contents
258 NOTE: These devices permit both read and write access.
260 block Loopback devices
261 0 = /dev/loop0 First loopback device
262 1 = /dev/loop1 Second loopback device
265 The loopback devices are used to mount filesystems not
266 associated with block devices. The binding to the
267 loopback devices is handled by mount(8) or losetup(8).
269 8 block SCSI disk devices (0-15)
270 0 = /dev/sda First SCSI disk whole disk
271 16 = /dev/sdb Second SCSI disk whole disk
272 32 = /dev/sdc Third SCSI disk whole disk
274 240 = /dev/sdp Sixteenth SCSI disk whole disk
276 Partitions are handled in the same way as for IDE
277 disks (see major number 3) except that the limit on
280 9 char SCSI tape devices
281 0 = /dev/st0 First SCSI tape, mode 0
282 1 = /dev/st1 Second SCSI tape, mode 0
284 32 = /dev/st0l First SCSI tape, mode 1
285 33 = /dev/st1l Second SCSI tape, mode 1
287 64 = /dev/st0m First SCSI tape, mode 2
288 65 = /dev/st1m Second SCSI tape, mode 2
290 96 = /dev/st0a First SCSI tape, mode 3
291 97 = /dev/st1a Second SCSI tape, mode 3
293 128 = /dev/nst0 First SCSI tape, mode 0, no rewind
294 129 = /dev/nst1 Second SCSI tape, mode 0, no rewind
296 160 = /dev/nst0l First SCSI tape, mode 1, no rewind
297 161 = /dev/nst1l Second SCSI tape, mode 1, no rewind
299 192 = /dev/nst0m First SCSI tape, mode 2, no rewind
300 193 = /dev/nst1m Second SCSI tape, mode 2, no rewind
302 224 = /dev/nst0a First SCSI tape, mode 3, no rewind
303 225 = /dev/nst1a Second SCSI tape, mode 3, no rewind
306 "No rewind" refers to the omission of the default
307 automatic rewind on device close. The MTREW or MTOFFL
308 ioctl()'s can be used to rewind the tape regardless of
309 the device used to access it.
311 block Metadisk (RAID) devices
312 0 = /dev/md0 First metadisk group
313 1 = /dev/md1 Second metadisk group
316 The metadisk driver is used to span a
317 filesystem across multiple physical disks.
319 10 char Non-serial mice, misc features

2592 **** ADDITIONAL /dev DIRECTORY ENTRIES
2594 This section details additional entries that should or may exist in
2595 the /dev directory. It is preferred that symbolic links use the same
2596 form (absolute or relative) as is indicated here. Links are
2597 classified as "hard" or "symbolic" depending on the preferred type of
2598 link; if possible, the indicated type of link should be used.
2603 These links should exist on all systems:
2605 /dev/fd /proc/self/fd symbolic File descriptors
2606 /dev/stdin fd/0 symbolic stdin file descriptor
2607 /dev/stdout fd/1 symbolic stdout file descriptor
2608 /dev/stderr fd/2 symbolic stderr file descriptor
2609 /dev/nfsd socksys symbolic Required by iBCS-2
2610 /dev/X0R null symbolic Required by iBCS-2
2612 Note: /dev/X0R is <letter X>-<digit 0>-<letter R>.
2616 It is recommended that these links exist on all systems:
2618 /dev/core /proc/kcore symbolic Backward compatibility
2619 /dev/ramdisk ram0 symbolic Backward compatibility
2620 /dev/ftape qft0 symbolic Backward compatibility
2621 /dev/bttv0 video0 symbolic Backward compatibility
2622 /dev/radio radio0 symbolic Backward compatibility
2623 /dev/i2o* /dev/i2o/* symbolic Backward compatibility
2624 /dev/scd? sr? hard Alternate SCSI CD-ROM name
2626 Locally defined links
2628 The following links may be established locally to conform to the
2629 configuration of the system. This is merely a tabulation of existing
2630 practice, and does not constitute a recommendation. However, if they
2631 exist, they should have the following uses.
2633 /dev/mouse mouse port symbolic Current mouse device
2634 /dev/tape tape device symbolic Current tape device
2635 /dev/cdrom CD-ROM device symbolic Current CD-ROM device
2636 /dev/cdwriter CD-writer symbolic Current CD-writer device
2637 /dev/scanner scanner symbolic Current scanner device
2638 /dev/modem modem port symbolic Current dialout device
2639 /dev/root root device symbolic Current root filesystem
2640 /dev/swap swap device symbolic Current swap device
2642 /dev/modem should not be used for a modem which supports dialin as
2643 well as dialout, as it tends to cause lock file problems. If it
2644 exists, /dev/modem should point to the appropriate primary TTY device
2645 (the use of the alternate callout devices is deprecated).
2647 For SCSI devices, /dev/tape and /dev/cdrom should point to the
2648 ``cooked'' devices (/dev/st* and /dev/sr*, respectively), whereas
2649 /dev/cdwriter and /dev/scanner should point to the appropriate generic
2650 SCSI devices (/dev/sg*).
2652 /dev/mouse may point to a primary serial TTY device, a hardware mouse
2653 device, or a socket for a mouse driver program (e.g. /dev/gpmdata).
2657 Non-transient sockets and named pipes may exist in /dev. Common entries are:
2659 /dev/printer socket lpd local socket
2660 /dev/log socket syslog local socket
2661 /dev/gpmdata socket gpm mouse multiplexer
2665 The following names are reserved for mounting special filesystems
2666 under /dev. These special filesystems provide kernel interfaces that
2667 cannot be provided with standard device nodes.
2669 /dev/pts devpts PTY slave filesystem
2670 /dev/shm shmfs POSIX shared memory maintenance access
2672 **** TERMINAL DEVICES
2674 Terminal, or TTY devices are a special class of character devices. A
2675 terminal device is any device that could act as a controlling terminal
2676 for a session; this includes virtual consoles, serial ports, and
2677 pseudoterminals (PTYs).
2679 All terminal devices share a common set of capabilities known as line
2680 diciplines; these include the common terminal line dicipline as well
2681 as SLIP and PPP modes.
2683 All terminal devices are named similarly; this section explains the
2684 naming and use of the various types of TTYs. Note that the naming
2685 conventions include several historical warts; some of these are
2686 Linux-specific, some were inherited from other systems, and some
2687 reflect Linux outgrowing a borrowed convention.
2689 A hash mark (#) in a device name is used here to indicate a decimal
2690 number without leading zeroes.
2692 Virtual consoles and the console device
2694 Virtual consoles are full-screen terminal displays on the system video
2695 monitor. Virtual consoles are named /dev/tty#, with numbering
2696 starting at /dev/tty1; /dev/tty0 is the current virtual console.
2697 /dev/tty0 is the device that should be used to access the system video
2698 card on those architectures for which the frame buffer devices
2699 (/dev/fb*) are not applicable. Do not use /dev/console
2702 The console device, /dev/console, is the device to which system
2703 messages should be sent, and on which logins should be permitted in
2704 single-user mode. Starting with Linux 2.1.71, /dev/console is managed
2705 by the kernel; for previous versions it should be a symbolic link to
2706 either /dev/tty0, a specific virtual console such as /dev/tty1, or to
2707 a serial port primary (tty*, not cu*) device, depending on the
2708 configuration of the system.
2712 Serial ports are RS-232 serial ports and any device which simulates
2713 one, either in hardware (such as internal modems) or in software (such
2714 as the ISDN driver.) Under Linux, each serial ports has two device
2715 names, the primary or callin device and the alternate or callout one.
2716 Each kind of device is indicated by a different letter. For any
2717 letter X, the names of the devices are /dev/ttyX# and /dev/cux#,
2718 respectively; for historical reasons, /dev/ttyS# and /dev/ttyC#
2719 correspond to /dev/cua# and /dev/cub#. In the future, it should be
2720 expected that multiple letters will be used; all letters will be upper
2721 case for the "tty" device (e.g. /dev/ttyDP#) and lower case for the
2722 "cu" device (e.g. /dev/cudp#).
2724 The names /dev/ttyQ# and /dev/cuq# are reserved for local use.
2726 The alternate devices provide for kernel-based exclusion and somewhat
2727 different defaults than the primary devices. Their main purpose is to
2728 allow the use of serial ports with programs with no inherent or broken
2729 support for serial ports. Their use is deprecated, and they may be
2730 removed from a future version of Linux.
2732 Arbitration of serial ports is provided by the use of lock files with
2733 the names /var/lock/LCK..ttyX#. The contents of the lock file should
2734 be the PID of the locking process as an ASCII number.
2736 It is common practice to install links such as /dev/modem
2737 which point to serial ports. In order to ensure proper locking in the
2738 presence of these links, it is recommended that software chase
2739 symlinks and lock all possible names; additionally, it is recommended
2740 that a lock file be installed with the corresponding alternate
2741 device. In order to avoid deadlocks, it is recommended that the locks
2742 are acquired in the following order, and released in the reverse:
2744 1. The symbolic link name, if any (/var/lock/LCK..modem)
2745 2. The "tty" name (/var/lock/LCK..ttyS2)
2746 3. The alternate device name (/var/lock/LCK..cua2)
2748 In the case of nested symbolic links, the lock files should be
2749 installed in the order the symlinks are resolved.
2751 Under no circumstances should an application hold a lock while waiting
2752 for another to be released. In addition, applications which attempt
2753 to create lock files for the corresponding alternate device names
2754 should take into account the possibility of being used on a non-serial
2755 port TTY, for which no alternate device would exist.
2757 Pseudoterminals (PTYs)
2759 Pseudoterminals, or PTYs, are used to create login sessions or provide
2760 other capabilities requiring a TTY line dicipline (including SLIP or
2761 PPP capability) to arbitrary data-generation processes. Each PTY has
2762 a master side, named /dev/pty[p-za-e][0-9a-f], and a slave side, named
2763 /dev/tty[p-za-e][0-9a-f]. The kernel arbitrates the use of PTYs by
2764 allowing each master side to be opened only once.
2766 Once the master side has been opened, the corresponding slave device
2767 can be used in the same manner as any TTY device. The master and
2768 slave devices are connected by the kernel, generating the equivalent
2769 of a bidirectional pipe with TTY capabilities.
2771 Recent versions of the Linux kernels and GNU libc contain support for
2772 the System V/Unix98 naming scheme for PTYs, which assigns a common
2773 device, /dev/ptmx, to all the masters (opening it will automatically
2774 give you a previously unassigned PTY) and a subdirectory, /dev/pts,
2775 for the slaves; the slaves are named with decimal integers (/dev/pts/#
2776 in our notation). This removes the problem of exhausting the
2777 namespace and enables the kernel to automatically create the device
2778 nodes for the slaves on demand using the "devpts" filesystem.
