A 2G/2G split is typically a good choice for a - generic Linux server with lots of RAM. - - Any potentially remaining (not permanently mapped) part of physical - memory is called 'high memory'. How much total high memory the kernel - can handle is influenced by the (next) High Memory configuration option. - - The actual amount of total physical memory will either be - autodetected or can be forced by using a kernel command line option - such as "mem=256M". (Try "man bootparam" or see the documentation of - your boot loader (lilo or loadlin) about how to pass options to the - kernel at boot time. The lilo procedure is also explained in the - SCSI-HOWTO, available from http://www.linuxdoc.org/docs.html#howto .) - Math emulation CONFIG_NWFPE Say Y to include the NWFPE floating point emulator in the kernel. diff --git a/Documentation/DocBook/Makefile b/Documentation/DocBook/Makefile index 155133a0a..368f037f7 100644 --- a/Documentation/DocBook/Makefile +++ b/Documentation/DocBook/Makefile @@ -26,8 +26,11 @@ kernel-api.sgml: kernel-api.tmpl $(TOPDIR)/arch/i386/kernel/mca.c \ $(TOPDIR)/arch/i386/kernel/mtrr.c \ $(TOPDIR)/drivers/char/misc.c \ - $(TOPDIR)/drivers/char/serial.c \ $(TOPDIR)/drivers/char/videodev.c \ + $(TOPDIR)/drivers/net/net_init.c \ + $(TOPDIR)/drivers/net/8390.c \ + $(TOPDIR)/drivers/char/serial.c \ + $(TOPDIR)/drivers/pci/pci.c \ $(TOPDIR)/drivers/sound/sound_core.c \ $(TOPDIR)/drivers/sound/sound_firmware.c \ $(TOPDIR)/drivers/net/wan/syncppp.c \ diff --git a/Documentation/DocBook/kernel-api.tmpl b/Documentation/DocBook/kernel-api.tmpl index 96dd9ecc0..f0013b011 100644 --- a/Documentation/DocBook/kernel-api.tmpl +++ b/Documentation/DocBook/kernel-api.tmpl @@ -49,7 +49,7 @@ </chapter> <chapter id="miscdev"> - <title>Miscellaneous Device</title> + <title>Miscellaneous Devices</title> !Edrivers/char/misc.c </chapter> @@ -58,6 +58,12 @@ !Edrivers/char/videodev.c </chapter> + <chapter id="netdev"> + <title>Network devices</title> +!Idrivers/net/net_init.c +!Edrivers/net/8390.c + </chapter> + <chapter id="snddev"> <title>Sound Devices</title> !Edrivers/sound/sound_core.c @@ -89,4 +95,9 @@ !Edrivers/net/wan/z85230.c </chapter> + <chapter id="pcilib"> + <title>PCI Support Library</title> +!Edrivers/pci/pci.c + </chapter> + </book> diff --git a/Documentation/devices.tex b/Documentation/devices.tex deleted file mode 100644 index f3767f5ef..000000000 --- a/Documentation/devices.tex +++ /dev/null @@ -1,2209 +0,0 @@ -\documentstyle{article} -% $Id: devices.tex,v 1.14 1998/08/10 22:39:24 hpa Exp $ -% --------------------------------------------------------------------------- -% Adopt somewhat reasonable margins, so it doesn't take a million -% pages to print... :-) If you're actually putting this in print, you -% may wish to change these. -\oddsidemargin=0in -\textwidth=6.5in -\topmargin=0in -\headheight=0.5in -\headsep=0.25in -\textheight=7.5in -\footskip=0.75in -\footheight=0.5in -% -\begin{document} -\newcommand{\file}{\tt} % Style to use for a filename -\newcommand{\url}{\it} % Style to use for an URL -\newcommand{\hex}{\tt} % Style to use for a hex number -\newcommand{\ud}{(Under development)} % Abbreviation -\newcommand{\1}{\({}^1\)} -\newcommand{\2}{\({}^2\)} -\newcommand{\3}{\({}^3\)} -\newcommand{\4}{\({}^4\)} -\newlength{\dig} -\settowidth{\dig}{0} % Get width of digits -\newcommand{\num}[2]{\makebox[#1\dig][r]{#2}} -\newcommand{\major}[4]{\num{3}{#1}#2 \> #3 \> #4 \\} -\newcommand{\minor}[3]{\> \> \num{3}{#1} \> {\file #2} \> #3 \\} -\newcommand{\minordots}{\> \> \> \dots \\} -\newenvironment{devicelist}% - {\begin{tabbing}% -000--000 \= blockxxx \= 000 \= {\file /dev/input/keyboardxxx} \= foo \kill}% - {\end{tabbing}} -\newcommand{\link}[4]{{\file #1} \> {\file #2} \> #3 \> #4 \\} -\newcommand{\vlink}[4]{{\file #1} \> {\em #2 \/} \> #3 \> #4 \\} -\newcommand{\node}[3]{{\file #1} \> #2 \> #3 \\} -\newcommand{\tum}{$''$} -\newenvironment{nodelist}% - {\begin{tabbing}% -{\file /dev/crambamboli} \= {\file /proc/self/fd/99} \= symbolicxxx \= -foo \kill}% - {\end{tabbing}} -% -% If you reformat this document, *please* make sure this information -% gets included!

It is also available separately -from {\url ftp://ftp.kernel.org/pub/linux/docs/device-list/}. In case -of discrepancy between the text and \LaTeX\ versions, the \LaTeX\ -version is authoritative. - -This document is included by reference into the Linux Filesystem -Standard (FSSTND). The FSSTND is available from -{\url ftp://tsx-11.mit.edu/pub/linux/docs/linux-standards/fsstnd/}. - -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. - -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. - -\section{How to submit a device entry} - -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 two 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, {\em please\/} include the -word ``device'' in the subject so your mail won't accidentally get -buried! I receive hundreds of email messages a day, so mail sent with -other subjects may very well get lost in the avalanche. - -Second, please include a description of the device {\em 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. - -Your cooperation is appreciated. -

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 in all cases used here to -indicate a decimal number without leading zeroes. - -\subsection{Virtual consoles and the console device} - -Virtual consoles are full-screen terminal displays on the system video -monitor. Virtual consoles are named {\file /dev/tty$\#$}, with -numbering starting at {\file /dev/tty1}; {\file /dev/tty0} is the -current virtual console. {\file /dev/tty0} is the device that should -be used to access the system video card on those architectures for -which the frame buffer devices ({\file /dev/fb*}) are not applicable. -Do not use {\file /dev/console} for this purpose. - -The {\em console device\/}, {\file /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, {\file -/dev/console} is managed by the kernel; for previous versions it -should be a symbolic link to either {\file /dev/tty0}, a specific -virtual console such as {\file /dev/tty1}, or to a serial port primary -({\file tty*}, not {\file cu*}) device, depending on the configuration -of the system. - -\subsection{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 {\file /dev/tty${X\#}$} and -{\file /dev/cu${x\#}$}, respectively; for historical reasons, {\file -/dev/ttyS$\#$} and {\file /dev/ttyC$\#$} correspond to {\file -/dev/cua$\#$} and {\file /dev/cub$\#$}. In the future, it should be -expected that multiple letters will be used; all letters will be upper -case for the {\file tty} device (e.g. {\file /dev/ttyDP$\#$} and lower -case for the {\file cu} device (e.g. {\file /dev/cudp$\#$}. - -The use of the callout devices is deprecated. - -The names {\file /dev/ttyQ$\#$} and {\file /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 {\file /var/lock/LCK..tty${X\#}$}. 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 {\file /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: -\begin{itemize} -\item{The symbolic link name, if any ({\file /var/lock/LCK..modem})} -\item{The {\file tty} name ({\file /var/lock/LCK..ttyS2})} -\item{The alternate device name ({\file /var/lock/LCK..cua2})} -\end{itemize} -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. - -\subsection{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 {\em master\/} side, named {\file /dev/pty[p-za-e][0-9a-f]\/}, and a -{\em slave\/} side, named {\file /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 {\file /dev/ptmx\/} to all the masters (opening it will -automatically give you a previously unassigned PTY) and a subdirectory -{\file /dev/pts\/} for the slaves; the slaves are named with decimal -integers ({\file /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 {\file devpts\/} filesystem. - -\end{document} diff --git a/Documentation/devices.txt b/Documentation/devices.txt index c17b77188..6332b478e 100644 --- a/Documentation/devices.txt +++ b/Documentation/devices.txt @@ -1,7 +1,7 @@ LINUX ALLOCATED DEVICES Maintained by H.
