Linux-2.6.12-rc2v2.6.12-rc2
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

+ LINUX ALLOCATED DEVICES (2.6+ version)
+
+ Maintained by Torben Mathiasen <device@lanana.org>
+
+ Last revised: 25 January 2005
+
+This list is the Linux Device List, the official registry of allocated
+device numbers and /dev directory nodes for the Linux operating
+system.
+
+The latest version of this list is available from
+http://www.lanana.org/docs/device-list/ or
+ftp://ftp.kernel.org/pub/linux/docs/device-list/. This version may be
+newer than the one distributed with the Linux kernel.
+
+The LaTeX version of this document is no longer maintained.
+
+This document is included by reference into the Filesystem Hierarchy
+Standard (FHS). The FHS is available from http://www.pathname.com/fhs/.
+
+Allocations marked (68k/Amiga) apply to Linux/68k on the Amiga
+platform only. Allocations marked (68k/Atari) apply to Linux/68k on
+the Atari platform only.
+
+The symbol {2.6} means the allocation is obsolete and scheduled for
+removal once kernel version 2.6 (or equivalent) is released. Some of these
+allocations have already been removed.
+
+This document is in the public domain. The author requests, however,
+that semantically altered versions are not distributed without
+permission of the author, assuming the author can be contacted without
+an unreasonable effort.
+
+In particular, please don't sent patches for this list to Linus, at
+least not without contacting me first.
+
+I do not have any information about these devices beyond what appears
+on this list. Any such information requests will be deleted without
+reply.
+
+
+ **** DEVICE DRIVERS AUTHORS PLEASE READ THIS ****
+
+To have a major number allocated, or a minor number in situations
+where that applies (e.g. busmice), please contact me with the
+appropriate device information. Also, if you have additional
+information regarding any of the devices listed below, or if I have
+made a mistake, I would greatly appreciate a note.
+
+I do, however, make a few requests about the nature of your report.
+This is necessary for me to be able to keep this list up to date and
+correct in a timely manner. First of all, *please* send it to the
+correct address... <device@lanana.org>. I receive hundreds of email
+messages a day, so mail sent to other addresses may very well get lost
+in the avalanche. Please put in a descriptive subject, so I can find
+your mail again should I need to. Too many people send me email
+saying just "device number request" in the subject.
+
+Second, please include a description of the device *in the same format
+as this list*. The reason for this is that it is the only way I have
+found to ensure I have all the requisite information to publish your
+device and avoid conflicts.
+
+Third, please don't assume that the distributed version of the list is
+up to date. Due to the number of registrations I have to maintain it
+in "batch mode", so there is likely additional registrations that
+haven't been listed yet.
+
+Finally, sometimes I have to play "namespace police." Please don't be
+offended. I often get submissions for /dev names that would be bound
+to cause conflicts down the road. I am trying to avoid getting in a
+situation where we would have to suffer an incompatible forward
+change. Therefore, please consult with me *before* you make your
+device names and numbers in any way public, at least to the point
+where it would be at all difficult to get them changed.
+
+Your cooperation is appreciated.
+
+
+ 0 Unnamed devices (e.g. non-device mounts)
+ 0 = reserved as null device number
+ See block major 144, 145, 146 for expansion areas.
+
+ 1 char Memory devices
+ 1 = /dev/mem Physical memory access
+ 2 = /dev/kmem Kernel virtual memory access
+ 3 = /dev/null Null device
+ 4 = /dev/port I/O port access
+ 5 = /dev/zero Null byte source
+ 6 = /dev/core OBSOLETE - replaced by /proc/kcore
+ 7 = /dev/full Returns ENOSPC on write
+ 8 = /dev/random Nondeterministic random number gen.
+ 9 = /dev/urandom Faster, less secure random number gen.
+ 10 = /dev/aio Asyncronous I/O notification interface
+ 11 = /dev/kmsg Writes to this come out as printk's
+ 1 block RAM disk
+ 0 = /dev/ram0 First RAM disk
+ 1 = /dev/ram1 Second RAM disk
+ ...
+ 250 = /dev/initrd Initial RAM disk {2.6}
+
+ Older kernels had /dev/ramdisk (1, 1) here.
+ /dev/initrd refers to a RAM disk which was preloaded
+ by the boot loader; newer kernels use /dev/ram0 for
+ the initrd.
+
+ 2 char Pseudo-TTY masters
+ 0 = /dev/ptyp0 First PTY master
+ 1 = /dev/ptyp1 Second PTY master
+ ...
+ 255 = /dev/ptyef 256th PTY master
+
+ Pseudo-tty's are named as follows:
+ * Masters are "pty", slaves are "tty";
+ * the fourth letter is one of pqrstuvwxyzabcde indicating
+ the 1st through 16th series of 16 pseudo-ttys each, and
+ * the fifth letter is one of 0123456789abcdef indicating
+ the position within the series.
+
+ These are the old-style (BSD) PTY devices; Unix98
+ devices are on major 128 and above and use the PTY
+ master multiplex (/dev/ptmx) to acquire a PTY on
+ demand.
+
+ 2 block Floppy disks

+ 112 = /dev/fd?u3840 3.5" 3840K Extra Density(1)
+
+ 36 = /dev/fd?CompaQ Compaq 2880K drive; obsolete?
+
+ (1) Autodetectable format
+ (2) Autodetectable format in a Double Density (720K) drive only
+ (3) Autodetectable format in a High Density (1440K) drive only
+
+ NOTE: The letter in the device name (d, q, h or u)
+ signifies the type of drive: 5.25" Double Density (d),
+ 5.25" Quad Density (q), 5.25" High Density (h) or 3.5"
+ (any model, u). The use of the capital letters D, H
+ and E for the 3.5" models have been deprecated, since
+ the drive type is insignificant for these devices.
+
+ 3 char Pseudo-TTY slaves
+ 0 = /dev/ttyp0 First PTY slave
+ 1 = /dev/ttyp1 Second PTY slave
+ ...
+ 255 = /dev/ttyef 256th PTY slave
+
+ These are the old-style (BSD) PTY devices; Unix98
+ devices are on major 136 and above.
+
+ 3 block First MFM, RLL and IDE hard disk/CD-ROM interface
+ 0 = /dev/hda Master: whole disk (or CD-ROM)
+ 64 = /dev/hdb Slave: whole disk (or CD-ROM)
+
+ For partitions, add to the whole disk device number:
+ 0 = /dev/hd? Whole disk
+ 1 = /dev/hd?1 First partition
+ 2 = /dev/hd?2 Second partition
+ ...
+ 63 = /dev/hd?63 63rd partition
+
+ For Linux/i386, partitions 1-4 are the primary
+ partitions, and 5 and above are logical partitions.
+ Other versions of Linux use partitioning schemes
+ appropriate to their respective architectures.
+
+ 4 char TTY devices
+ 0 = /dev/tty0 Current virtual console
+
+ 1 = /dev/tty1 First virtual console
+ ...
+ 63 = /dev/tty63 63rd virtual console
+ 64 = /dev/ttyS0 First UART serial port
+ ...
+ 255 = /dev/ttyS191 192nd UART serial port
+
+ UART serial ports refer to 8250/16450/16550 series devices.
+
+ Older versions of the Linux kernel used this major
+ number for BSD PTY devices. As of Linux 2.1.115, this
+ is no longer supported. Use major numbers 2 and 3.
+
+ 4 block Aliases for dynamically allocated major devices to be used
+ when its not possible to create the real device nodes
+ because the root filesystem is mounted read-only.
+
+ 0 = /dev/root

+ ...
+ 255 = /dev/cua191 Callout device for ttyS191
+
+ (5,1) is /dev/console starting with Linux 2.1.71. See
+ the section on terminal devices for more information
+ on /dev/console.
+
+ 6 char Parallel printer devices
+ 0 = /dev/lp0 Parallel printer on parport0
+ 1 = /dev/lp1 Parallel printer on parport1
+ ...
+
+ Current Linux kernels no longer have a fixed mapping
+ between parallel ports and I/O addresses. Instead,
+ they are redirected through the parport multiplex layer.
+
+ 7 char Virtual console capture devices
+ 0 = /dev/vcs Current vc text contents
+ 1 = /dev/vcs1 tty1 text contents
+ ...
+ 63 = /dev/vcs63 tty63 text contents
+ 128 = /dev/vcsa Current vc text/attribute contents
+ 129 = /dev/vcsa1 tty1 text/attribute contents

+
+ NOTE: These devices permit both read and write access.
+
+ 7 block Loopback devices
+ 0 = /dev/loop0 First loopback device
+ 1 = /dev/loop1 Second loopback device
+ ...
+
+ The loopback devices are used to mount filesystems not
+ associated with block devices. The binding to the
+ loopback devices is handled by mount(8) or losetup(8).
+
+ 8 block SCSI disk devices (0-15)
+ 0 = /dev/sda First SCSI disk whole disk
+ 16 = /dev/sdb Second SCSI disk whole disk
+ 32 = /dev/sdc Third SCSI disk whole disk
+ ...
+ 240 = /dev/sdp Sixteenth SCSI disk whole disk
+
+ Partitions are handled in the same way as for IDE
+ disks (see major number 3) except that the limit on
+ partitions is 15.
+
+ 9 char SCSI tape devices
+ 0 = /dev/st0 First SCSI tape, mode 0
+ 1 = /dev/st1 Second SCSI tape, mode 0
+ ...
+ 32 = /dev/st0l First SCSI tape, mode 1

+ 97 = /dev/st1a Second SCSI tape, mode 3
+ ...
+ 128 = /dev/nst0 First SCSI tape, mode 0, no rewind
+ 129 = /dev/nst1 Second SCSI tape, mode 0, no rewind
+ ...
+ 160 = /dev/nst0l First SCSI tape, mode 1, no rewind

+ ...
+ 224 = /dev/nst0a First SCSI tape, mode 3, no rewind
+ 225 = /dev/nst1a Second SCSI tape, mode 3, no rewind
+ ...
+
+ "No rewind" refers to the omission of the default
+ automatic rewind on device close. The MTREW or MTOFFL
+ ioctl()'s can be used to rewind the tape regardless of
+ the device used to access it.
+
+ 9 block Metadisk (RAID) devices
+ 0 = /dev/md0 First metadisk group
+ 1 = /dev/md1 Second metadisk group
+ ...
+
+ The metadisk driver is used to span a

+
+ **** ADDITIONAL /dev DIRECTORY ENTRIES
+
+This section details additional entries that should or may exist in
+the /dev directory. It is preferred that symbolic links use the same
+form (absolute or relative) as is indicated here. Links are
+classified as "hard" or "symbolic" depending on the preferred type of
+link; if possible, the indicated type of link should be used.
+
+
+ Compulsory links
+
+These links should exist on all systems:
+
+/dev/fd /proc/self/fd symbolic File descriptors
+/dev/stdin fd/0 symbolic stdin file descriptor
+/dev/stdout fd/1 symbolic stdout file descriptor
+/dev/stderr fd/2 symbolic stderr file descriptor
+/dev/nfsd socksys symbolic Required by iBCS-2
+/dev/X0R null symbolic Required by iBCS-2
+
+Note: /dev/X0R is <letter X>-<digit 0>-<letter R>.
+
+ Recommended links
+
+It is recommended that these links exist on all systems:
+
+/dev/core /proc/kcore symbolic Backward compatibility
+/dev/ramdisk ram0 symbolic Backward compatibility
+/dev/ftape qft0 symbolic Backward compatibility
+/dev/bttv0 video0 symbolic Backward compatibility
+/dev/radio radio0 symbolic Backward compatibility
+/dev/i2o* /dev/i2o/* symbolic Backward compatibility
+/dev/scd? sr? hard Alternate SCSI CD-ROM name
+
+ Locally defined links
+
+The following links may be established locally to conform to the
+configuration of the system. This is merely a tabulation of existing
+practice, and does not constitute a recommendation. However, if they
+exist, they should have the following uses.
+
+/dev/mouse mouse port symbolic Current mouse device
+/dev/tape tape device symbolic Current tape device
+/dev/cdrom CD-ROM device symbolic Current CD-ROM device
+/dev/cdwriter CD-writer symbolic Current CD-writer device
+/dev/scanner scanner symbolic Current scanner device
+/dev/modem modem port symbolic Current dialout device
+/dev/root root device symbolic Current root filesystem
+/dev/swap swap device symbolic Current swap device
+
+/dev/modem should not be used for a modem which supports dialin as
+well as dialout, as it tends to cause lock file problems. If it
+exists, /dev/modem should point to the appropriate primary TTY device
+(the use of the alternate callout devices is deprecated).
+
+For SCSI devices, /dev/tape and /dev/cdrom should point to the
+``cooked'' devices (/dev/st* and /dev/sr*, respectively), whereas
+/dev/cdwriter and /dev/scanner should point to the appropriate generic
+SCSI devices (/dev/sg*).
+
+/dev/mouse may point to a primary serial TTY device, a hardware mouse
+device, or a socket for a mouse driver program (e.g. /dev/gpmdata).
+
+ Sockets and pipes
+
+Non-transient sockets and named pipes may exist in /dev. Common entries are:
+
+/dev/printer socket lpd local socket
+/dev/log socket syslog local socket
+/dev/gpmdata socket gpm mouse multiplexer
+
+ Mount points
+
+The following names are reserved for mounting special filesystems
+under /dev. These special filesystems provide kernel interfaces that
+cannot be provided with standard device nodes.
+
+/dev/pts devpts PTY slave filesystem
+/dev/shm tmpfs POSIX shared memory maintenance access
+
+ **** TERMINAL DEVICES
+
+Terminal, or TTY devices are a special class of character devices. A
+terminal device is any device that could act as a controlling terminal
+for a session; this includes virtual consoles, serial ports, and
+pseudoterminals (PTYs).
+
+All terminal devices share a common set of capabilities known as line
+diciplines; these include the common terminal line dicipline as well
+as SLIP and PPP modes.
+
+All terminal devices are named similarly; this section explains the
+naming and use of the various types of TTYs. Note that the naming
+conventions include several historical warts; some of these are
+Linux-specific, some were inherited from other systems, and some
+reflect Linux outgrowing a borrowed convention.
+
+A hash mark (#) in a device name is used here to indicate a decimal
+number without leading zeroes.
+
+ Virtual consoles and the console device
+
+Virtual consoles are full-screen terminal displays on the system video
+monitor. Virtual consoles are named /dev/tty#, with numbering
+starting at /dev/tty1; /dev/tty0 is the current virtual console.
+/dev/tty0 is the device that should be used to access the system video
+card on those architectures for which the frame buffer devices
+(/dev/fb*) are not applicable. Do not use /dev/console
+for this purpose.
+
+The console device, /dev/console, is the device to which system
+messages should be sent, and on which logins should be permitted in
+single-user mode. Starting with Linux 2.1.71, /dev/console is managed
+by the kernel; for previous versions it should be a symbolic link to
+either /dev/tty0, a specific virtual console such as /dev/tty1, or to
+a serial port primary (tty*, not cu*) device, depending on the
+configuration of the system.
+
+ Serial ports
+
+Serial ports are RS-232 serial ports and any device which simulates
+one, either in hardware (such as internal modems) or in software (such
+as the ISDN driver.) Under Linux, each serial ports has two device
+names, the primary or callin device and the alternate or callout one.
+Each kind of device is indicated by a different letter. For any
+letter X, the names of the devices are /dev/ttyX# and /dev/cux#,
+respectively; for historical reasons, /dev/ttyS# and /dev/ttyC#
+correspond to /dev/cua# and /dev/cub#. In the future, it should be
+expected that multiple letters will be used; all letters will be upper
+case for the "tty" device (e.g. /dev/ttyDP#) and lower case for the
+"cu" device (e.g. /dev/cudp#).
+
+The names /dev/ttyQ# and /dev/cuq# are reserved for local use.
+
+The alternate devices provide for kernel-based exclusion and somewhat
+different defaults than the primary devices. Their main purpose is to
+allow the use of serial ports with programs with no inherent or broken
+support for serial ports. Their use is deprecated, and they may be
+removed from a future version of Linux.
+
+Arbitration of serial ports is provided by the use of lock files with
+the names /var/lock/LCK..ttyX#. The contents of the lock file should
+be the PID of the locking process as an ASCII number.
+
+It is common practice to install links such as /dev/modem
+which point to serial ports. In order to ensure proper locking in the
+presence of these links, it is recommended that software chase
+symlinks and lock all possible names; additionally, it is recommended
+that a lock file be installed with the corresponding alternate
+device. In order to avoid deadlocks, it is recommended that the locks
+are acquired in the following order, and released in the reverse:
+
+ 1. The symbolic link name, if any (/var/lock/LCK..modem)
+ 2. The "tty" name (/var/lock/LCK..ttyS2)
+ 3. The alternate device name (/var/lock/LCK..cua2)
+
+In the case of nested symbolic links, the lock files should be
+installed in the order the symlinks are resolved.
+
+Under no circumstances should an application hold a lock while waiting
+for another to be released. In addition, applications which attempt
+to create lock files for the corresponding alternate device names
+should take into account the possibility of being used on a non-serial
+port TTY, for which no alternate device would exist.
+
+ Pseudoterminals (PTYs)
+
+Pseudoterminals, or PTYs, are used to create login sessions or provide
+other capabilities requiring a TTY line dicipline (including SLIP or
+PPP capability) to arbitrary data-generation processes. Each PTY has
+a master side, named /dev/pty[p-za-e][0-9a-f], and a slave side, named
+/dev/tty[p-za-e][0-9a-f]. The kernel arbitrates the use of PTYs by
+allowing each master side to be opened only once.
+
+Once the master side has been opened, the corresponding slave device
+can be used in the same manner as any TTY device. The master and
+slave devices are connected by the kernel, generating the equivalent
+of a bidirectional pipe with TTY capabilities.
+
+Recent versions of the Linux kernels and GNU libc contain support for
+the System V/Unix98 naming scheme for PTYs, which assigns a common
+device, /dev/ptmx, to all the masters (opening it will automatically
+give you a previously unassigned PTY) and a subdirectory, /dev/pts,
+for the slaves; the slaves are named with decimal integers (/dev/pts/#
+in our notation). This removes the problem of exhausting the
+namespace and enables the kernel to automatically create the device
+nodes for the slaves on demand using the "devpts" filesystem.
