This list is the successor to Rick Miller's Linux Device List, which
|
| 50 |
|
|
he stopped maintaining when he got busy with other things in 1993. It
|
| 51 |
|
|
is a registry of allocated major device numbers, as well as the
|
| 52 |
|
|
recommended {\file /dev} directory nodes for these devices.
|
| 53 |
|
|
|
| 54 |
|
|
The latest version of this list is included with the Linux kernel
|
| 55 |
|
|
sources in \LaTeX\ and ASCII form. In case of discrepancy, the
|
| 56 |
|
|
\LaTeX\ version is authoritative.
|
| 57 |
|
|
|

|
|
This document is included by reference into the Linux Filesystem
|
| 59 |
|
|
Standard (FSSTND). The FSSTND is available via FTP from
|
| 60 |
|
|
tsx-11.mit.edu in the directory {\file
|
| 61 |
|
|
/pub/linux/docs/linux-standards/fsstnd}.
|
| 62 |
|
|
|
| 63 |
|
|
To have a major number allocated, or a minor number in situations
|
| 64 |
|
|
where that applies (e.g.\ busmice), please contact me with the
|
| 65 |
|
|
appropriate device information. Also, if you have additional
|
| 66 |
|
|
information regarding any of the devices listed below, or if I have
|
| 67 |
|
|
made a mistake, I would greatly appreciate a note. When sending me
|
| 68 |
|
|
mail, please include the word ``device'' in the subject so your mail
|
| 69 |
|
|
won't accidentally get buried!
|
| 70 |
|
|
|
| 71 |
|
|
Allocations marked (68k/Amiga) apply to Linux/68k on the Amiga
|
| 72 |
|
|
platform only. Allocations marked (68k/Atari) apply to Linux/68k on
|
| 73 |
|
|
the Atari platform only.

This document is in the public domain. The author requests, however,
|
| 76 |
|
|
that semantically altered versions are not distributed without
|
| 77 |
|
|
permission of the author, assuming the author can be contacted without
|
| 78 |
|
|
an unreasonable effort.
|
| 79 |
|
|
|
| 80 |
|
|
In particular, please don't sent patches for this list to Linus, at
|
| 81 |
|
|
least not without contacting me first.
|
| 82 |
|
|
|
| 83 |
|
|
I do not have any information about these devices beyond what appears
|
| 84 |
|
|
on this list. Any such information requests will be deleted without
|
| 85 |
|
|
reply.

number 3) except that the partition limit is 15 rather than 63 per

The universal frame buffer device is currently supported only on
|
| 779 |
|
|
Linux/68k and Linux/SPARC. The plain device accesses the frame
|
| 780 |
|
|
buffer at current resolution (Linux/68k calls this file {\file
|
| 781 |
|
|
current}, e.g. {\file /dev/fb0current}); the {\file autodetect} one at
|
| 782 |
|
|
bootup (default) resolution. Minor numbers 2--23 within each frame
|
| 783 |
|
|
buffer assignment are used for specific device-dependent resolutions.
|
| 784 |
|
|
There appears to be no standard naming for these devices. Finally,
|
| 785 |
|
|
24--31 within each device are reserved for user-selected modes,
|
| 786 |
|
|
usually entered at boot time. Currently only Linux/68k uses the
|
| 787 |
|
|
mode-specific devices.

\section{Additional /dev directory entries}
|
| 1151 |
|
|
|
| 1152 |
|
|
This section details additional entries that should or may exist in the
|
| 1153 |
|
|
{\file /dev} directory. It is preferred that symbolic links use the
|
| 1154 |
|
|
same form (absolute or relative) as is indicated here. Links are
|
| 1155 |
|
|
classified as {\em hard\/} or {\em symbolic\/} depending on the
|
| 1156 |
|
|
preferred type of link; if possible, the indicated type of link should
|
| 1157 |
|
|
be used.
|
| 1158 |
|
|
|
| 1159 |
|
|
\subsection{Compulsory links}
|
| 1160 |
|
|
|
| 1161 |
|
|
These links should exist on all systems:
|
| 1162 |
|
|
|
| 1163 |
|
|
\begin{nodelist}
|
| 1164 |
|
|
\link{/dev/fd}{/proc/self/fd}{symbolic}{File descriptors}
|
| 1165 |
|
|
\link{/dev/stdin}{fd/0}{symbolic}{Standard input file descriptor}
|
| 1166 |
|
|
\link{/dev/stdout}{fd/1}{symbolic}{Standard output file descriptor}
|
| 1167 |
|
|
\link{/dev/stderr}{fd/2}{symbolic}{Standard error file descriptor}
|
| 1168 |
|
|
\link{/dev/nfsd}{socksys}{symbolic}{Required by iBCS-2}
|
| 1169 |
|
|
\link{/dev/X0R}{null}{symbolic}{Required by iBCS-2}
|
| 1170 |
|
|
\end{nodelist}
|
| 1171 |
|
|
|
| 1172 |
|
|
\noindent
|
| 1173 |
|
|
Note: The last device is: $<$letter {\tt X}$>$-$<$digit {\tt
|
| 1174 |
|
|
0}$>$-$<$letter {\tt R}$>$.
|
| 1175 |
|
|
|
| 1176 |
|
|
\subsection{Recommended links}
|
| 1177 |
|
|
|
| 1178 |
|
|
It is recommended that these links exist on all systems:
|
| 1179 |
|
|
|
| 1180 |
|
|
\begin{nodelist}
|
| 1181 |
|
|
\link{/dev/core}{/proc/kcore}{symbolic}{Backward compatibility}
|
| 1182 |
|
|
\link{/dev/ramdisk}{ram0}{symbolic}{Backward compatibility}
|
| 1183 |
|
|
\link{/dev/ftape}{rft0}{symbolic}{Backward compatibility}
|
| 1184 |
|
|
\link{/dev/scd?}{sr?}{hard}{Alternate name for CD-ROMs}
|
| 1185 |
|
|

|
%\link{/dev/fd?E*}{fd?D*}{hard}{Compatible floppy formats}
|
| 1187 |
|
|
%\link{/dev/fd?E*}{fd?H*}{hard}{Compatible floppy formats}
|
| 1188 |
|
|
\end{nodelist}
|
| 1189 |
|
|
|
| 1190 |
|
|
\subsection{Locally defined links}
|
| 1191 |
|
|
|
| 1192 |
|
|
The following links may be established locally to conform to the
|
| 1193 |
|
|
configuration of the system. This is merely a tabulation of existing
|
| 1194 |
|
|
practice, and does not constitute a recommendation. However, if they
|
| 1195 |
|
|
exist, they should have the following uses.
|
| 1196 |
|
|
|
| 1197 |
|
|
\begin{nodelist}
|
| 1198 |
|
|
\vlink{/dev/mouse}{mouse port}{symbolic}{Current mouse device}
|
| 1199 |
|
|
\vlink{/dev/tape}{tape device}{symbolic}{Current tape device}
|
| 1200 |
|
|
\vlink{/dev/cdrom}{CD-ROM device}{symbolic}{Current CD-ROM device}
|
| 1201 |
|
|
\vlink{/dev/cdwriter}{CD-writer}{symbolic}{Current CD-writer device}
|
| 1202 |
|
|
\vlink{/dev/scanner}{scanner device}{symbolic}{Current scanner device}
|
| 1203 |
|
|
\vlink{/dev/modem}{modem port}{symbolic}{Current dialout device}
|
| 1204 |
|
|
\vlink{/dev/root}{root device}{symbolic}{Current root filesystem}
|
| 1205 |
|
|
\vlink{/dev/swap}{swap device}{symbolic}{Current swap device}
|
| 1206 |
|
|
\end{nodelist}
|
| 1207 |
|
|
|
| 1208 |
|
|
\noindent
|
| 1209 |
|
|
{\file /dev/modem} should not be used for a modem which supports
|
| 1210 |
|
|
dialin as well as dialout, as it tends to cause lock file problems.
|
| 1211 |
|
|
If it exists, {\file /dev/modem} should point to the appropriate
|
| 1212 |
|
|
dialout (alternate) device.
|
| 1213 |
|
|
|
| 1214 |
|
|
For SCSI devices, {\file /dev/tape} and {\file /dev/cdrom} should
|
| 1215 |
|
|
point to the ``cooked'' devices ({\file /dev/st*} and {\file
|
| 1216 |
|
|
/dev/sr*}, respectively), whereas {\file /dev/cdwriter} and {\file
|
| 1217 |
|
|
/dev/scanner} should point to the appropriate generic SCSI devices
|
| 1218 |
|
|
({\file /dev/sg*}.)
|
| 1219 |
|
|
|
| 1220 |
|
|
{\file /dev/mouse} may point to a primary serial TTY device, a
|
| 1221 |
|
|
hardware mouse device, or a socket for a mouse driver program
|
| 1222 |
|
|
(e.g. {\file /dev/gpmdata}.)
|
| 1223 |
|
|
|
| 1224 |
|
|
\subsection{Sockets and pipes}
|
| 1225 |
|
|
|
| 1226 |
|
|
Non-transient sockets or named pipes may exist in {\file /dev}.
|
| 1227 |
|
|
Common entries are:
|
| 1228 |
|
|
|
| 1229 |
|
|
\begin{nodelist}
|
| 1230 |
|
|
