Based on kernel version 4.16.1. Page generated on 2018-04-09 11:52 EST.

1	   0		Unnamed devices (e.g. non-device mounts)
2			  0 = reserved as null device number
3			See block major 144, 145, 146 for expansion areas.
4	
5	   1 char	Memory devices
6			  1 = /dev/mem		Physical memory access
7			  2 = /dev/kmem		Kernel virtual memory access
8			  3 = /dev/null		Null device
9			  4 = /dev/port		I/O port access
10			  5 = /dev/zero		Null byte source
11			  6 = /dev/core		OBSOLETE - replaced by /proc/kcore
12			  7 = /dev/full		Returns ENOSPC on write
13			  8 = /dev/random	Nondeterministic random number gen.
14			  9 = /dev/urandom	Faster, less secure random number gen.
15			 10 = /dev/aio		Asynchronous I/O notification interface
16			 11 = /dev/kmsg		Writes to this come out as printk's, reads
17						export the buffered printk records.
18			 12 = /dev/oldmem	OBSOLETE - replaced by /proc/vmcore
19	
20	   1 block	RAM disk
21			  0 = /dev/ram0		First RAM disk
22			  1 = /dev/ram1		Second RAM disk
23			    ...
24			250 = /dev/initrd	Initial RAM disk
25	
26			Older kernels had /dev/ramdisk (1, 1) here.
27			/dev/initrd refers to a RAM disk which was preloaded
28			by the boot loader; newer kernels use /dev/ram0 for
29			the initrd.
30	
31	   2 char	Pseudo-TTY masters
32			  0 = /dev/ptyp0	First PTY master
33			  1 = /dev/ptyp1	Second PTY master
34			    ...
35			255 = /dev/ptyef	256th PTY master
36	
37			Pseudo-tty's are named as follows:
38			* Masters are "pty", slaves are "tty";
39			* the fourth letter is one of pqrstuvwxyzabcde indicating
40			  the 1st through 16th series of 16 pseudo-ttys each, and
41			* the fifth letter is one of 0123456789abcdef indicating
42			  the position within the series.
43	
44			These are the old-style (BSD) PTY devices; Unix98
45			devices are on major 128 and above and use the PTY
46			master multiplex (/dev/ptmx) to acquire a PTY on
47			demand.
48	
49	   2 block	Floppy disks
50			  0 = /dev/fd0		Controller 0, drive 0, autodetect

56			130 = /dev/fd6		Controller 1, drive 2, autodetect
57			131 = /dev/fd7		Controller 1, drive 3, autodetect
58	
59			To specify format, add to the autodetect device number:

86			116 = /dev/fd?u1840	3.5"  1840K High Density(3)
87			100 = /dev/fd?u1920	3.5"  1920K High Density(1)

92	
93			 36 = /dev/fd?CompaQ	Compaq 2880K drive; obsolete?
94	
95			(1) Autodetectable format
96			(2) Autodetectable format in a Double Density (720K) drive only
97			(3) Autodetectable format in a High Density (1440K) drive only
98	
99			NOTE: The letter in the device name (d, q, h or u)
100			signifies the type of drive: 5.25" Double Density (d),
101			5.25" Quad Density (q), 5.25" High Density (h) or 3.5"
102			(any model, u).	 The use of the capital letters D, H
103			and E for the 3.5" models have been deprecated, since
104			the drive type is insignificant for these devices.
105	
106	   3 char	Pseudo-TTY slaves
107			  0 = /dev/ttyp0	First PTY slave
108			  1 = /dev/ttyp1	Second PTY slave
109			    ...
110			255 = /dev/ttyef	256th PTY slave
111	
112			These are the old-style (BSD) PTY devices; Unix98
113			devices are on major 136 and above.
114	
115	   3 block	First MFM, RLL and IDE hard disk/CD-ROM interface
116			  0 = /dev/hda		Master: whole disk (or CD-ROM)
117			 64 = /dev/hdb		Slave: whole disk (or CD-ROM)
118	
119			For partitions, add to the whole disk device number:
120			  0 = /dev/hd?		Whole disk
121			  1 = /dev/hd?1		First partition
122			  2 = /dev/hd?2		Second partition
123			    ...
124			 63 = /dev/hd?63	63rd partition
125	
126			For Linux/i386, partitions 1-4 are the primary
127			partitions, and 5 and above are logical partitions.
128			Other versions of Linux use partitioning schemes
129			appropriate to their respective architectures.
130	
131	   4 char	TTY devices
132			  0 = /dev/tty0		Current virtual console
133

142	
143			Older versions of the Linux kernel used this major
144			number for BSD PTY devices.  As of Linux 2.1.115, this
145			is no longer supported.	 Use major numbers 2 and 3.
146

148			when its not possible to create the real device nodes
149			because the root filesystem is mounted read-only.

151			   0 = /dev/root
152	
153	   5 char	Alternate TTY devices

171			Current Linux kernels no longer have a fixed mapping
172			between parallel ports and I/O addresses.  Instead,
173			they are redirected through the parport multiplex layer.
174	
175	   7 char	Virtual console capture devices
176			  0 = /dev/vcs		Current vc text contents
177			  1 = /dev/vcs1		tty1 text contents

195	
196	   8 block	SCSI disk devices (0-15)
197			  0 = /dev/sda		First SCSI disk whole disk
198			 16 = /dev/sdb		Second SCSI disk whole disk

215			 65 = /dev/st1m		Second SCSI tape, mode 2
216			    ...
217			 96 = /dev/st0a		First SCSI tape, mode 3
218			 97 = /dev/st1a		Second SCSI tape, mode 3
219			      ...
220			128 = /dev/nst0		First SCSI tape, mode 0, no rewind
221			129 = /dev/nst1		Second SCSI tape, mode 0, no rewind
222			    ...
223			160 = /dev/nst0l	First SCSI tape, mode 1, no rewind
224			161 = /dev/nst1l	Second SCSI tape, mode 1, no rewind
225			    ...

230			225 = /dev/nst1a	Second SCSI tape, mode 3, no rewind
231			    ...
232	
233			"No rewind" refers to the omission of the default
234			automatic rewind on device close.  The MTREW or MTOFFL
235			ioctl()'s can be used to rewind the tape regardless of
236			the device used to access it.
237	
238	   9 block	Metadisk (RAID) devices
239			  0 = /dev/md0		First metadisk group
240			  1 = /dev/md1		Second metadisk group
241			    ...
