Linux中常见硬件设备的文件名

  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
                  0 = /dev/fd0          Controller 0, drive 0, autodetect
                  1 = /dev/fd1          Controller 0, drive 1, autodetect
                  2 = /dev/fd2          Controller 0, drive 2, autodetect
                  3 = /dev/fd3          Controller 0, drive 3, autodetect
                128 = /dev/fd4          Controller 1, drive 0, autodetect
                129 = /dev/fd5          Controller 1, drive 1, autodetect

                131 = /dev/fd7          Controller 1, drive 3, autodetect

                To specify format, add to the autodetect device number:
                  0 = /dev/fd?          Autodetect format
                  4 = /dev/fd?d360      5.25"  360K in a 360K  drive(1)
                 20 = /dev/fd?h360      5.25"  360K in a 1200K drive(1)
                 48 = /dev/fd?h410      5.25"  410K in a 1200K drive

                 24 = /dev/fd?h720      5.25"  720K in a 1200K drive
                 80 = /dev/fd?h880      5.25"  880K in a 1200K drive(1)
                  8 = /dev/fd?h1200     5.25" 1200K in a 1200K drive(1)
                 40 = /dev/fd?h1440     5.25" 1440K in a 1200K drive(1)
                 56 = /dev/fd?h1476     5.25" 1476K in a 1200K drive
                 72 = /dev/fd?h1494     5.25" 1494K in a 1200K drive
                 92 = /dev/fd?h1600     5.25" 1600K in a 1200K drive(1)

                 12 = /dev/fd?u360      3.5"   360K Double Density(2)

                 52 = /dev/fd?u820      3.5"   820K Double Density
                 68 = /dev/fd?u830      3.5"   830K Double Density

                 28 = /dev/fd?u1440     3.5"  1440K High Density(1)
                124 = /dev/fd?u1600     3.5"  1600K High Density(1)
                 44 = /dev/fd?u1680     3.5"  1680K High Density(3)
                 60 = /dev/fd?u1722     3.5"  1722K High Density
                 76 = /dev/fd?u1743     3.5"  1743K High Density
                 96 = /dev/fd?u1760     3.5"  1760K High Density
                116 = /dev/fd?u1840     3.5"  1840K High Density(3)
                100 = /dev/fd?u1920     3.5"  1920K High Density(1)
                 32 = /dev/fd?u2880     3.5"  2880K Extra Density(1)
                104 = /dev/fd?u3200     3.5"  3200K Extra Density
                108 = /dev/fd?u3520     3.5"  3520K Extra Density
                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

  5 char        Alternate TTY devices
                  0 = /dev/tty          Current TTY device
                  1 = /dev/console      System console
                  2 = /dev/ptmx         PTY master multiplex
                 64 = /dev/cua0         Callout device for ttyS0
                    ...
                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
                    ...
                191 = /dev/vcsa63       tty63 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
                 33 = /dev/st1l         Second SCSI tape, mode 1
                    ...
                 64 = /dev/st0m         First SCSI tape, mode 2
                 65 = /dev/st1m         Second SCSI tape, mode 2
                    ...
                 96 = /dev/st0a         First SCSI tape, mode 3
                 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
                161 = /dev/nst1l        Second SCSI tape, mode 1, no rewind
                    ...
                192 = /dev/nst0m        First SCSI tape, mode 2, no rewind
                193 = /dev/nst1m        Second SCSI tape, mode 2, 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
                filesystem across multiple physical disks.

 10 char        Non-serial mice, misc features
                  0 = /dev/logibm       Logitech bus mouse
                  1 = /dev/psaux        PS/2-style mouse port

                  4 = /dev/amigamouse   Amiga mouse (68k/Amiga)
                  5 = /dev/atarimouse   Atari mouse
                  6 = /dev/sunmouse     Sun mouse
                  7 = /dev/amigamouse1  Second Amiga mouse
                  8 = /dev/smouse       Simple serial mouse driver

                 11 = /dev/vrtpanel     Vr41xx embedded touch panel
                 13 = /dev/vpcmouse     Connectix Virtual PC Mouse
                 14 = /dev/touchscreen/ucb1x00  UCB 1x00 touchscreen
                 15 = /dev/touchscreen/mk712    MK712 touchscreen
                128 = /dev/beep         Fancy beep device
                129 = /dev/modreq       Kernel module load request {2.6}
