||||||
.Sh DESCRIPTION
|
|
||||||
This section describes the special files, related driver functions,
|
|
||||||
and networking support available in the system.
|
|
||||||
In this part of the manual, the
|
|
||||||
.Tn SYNOPSIS
|
|
||||||
section of each configurable device gives a sample specification
|
|
||||||
for use in constructing a system description for the
|
|
||||||
.Xr config 8
|
|
||||||
program.
|
|
||||||
The
|
|
||||||
.Tn DIAGNOSTICS
|
|
||||||
section lists messages which may appear on the console
|
|
||||||
and/or in the system error log
|
|
||||||
.Pa /var/log/messages
|
|
||||||
due to errors in device operation; see
|
|
||||||
.Xr syslogd 8
|
|
||||||
for more information.
|
|
||||||
.Pp
|
|
||||||
This section contains both devices which may be configured into
|
|
||||||
the system and network related information.
|
|
||||||
The networking support is introduced in
|
|
||||||
.Xr netintro 4 .
|
|
||||||
.Sh DEVICE SUPPORT
|
|
||||||
This section describes the hardware supported by
|
|
||||||
.Nx Ns /arc .
|
|
||||||
Software support for these devices comes in two forms. A hardware
|
|
||||||
device may be supported with a character or block
|
|
||||||
.Em device driver ,
|
|
||||||
or it may be used within the networking subsystem and have a
|
|
||||||
.Em network interface driver .
|
|
||||||
Block and character devices are accessed through files in the file
|
|
||||||
system of a special type; see
|
|
||||||
.Xr mknod 8 .
|
|
||||||
Network interfaces are indirectly accessed through the interprocess
|
|
||||||
communication facilities provided by the system; see
|
|
||||||
.Xr socket 2 .
|
|
||||||
.Pp
|
|
||||||
A hardware device is identified to the system at configuration time
|
|
||||||
and the appropriate device or network interface driver is then
|
|
||||||
compiled into the system. When the resultant system is booted, the
|
|
||||||
autoconfiguration facilities in the system probe for the device and,
|
|
||||||
if found, enable the software support for it. If a device does not
|
|
||||||
respond at autoconfiguration time it is not accessible at any time
|
|
||||||
afterwards. To enable a device which did not autoconfigure, the
|
|
||||||
system must be rebooted.
|
|
||||||
.Pp
|
|
||||||
The autoconfiguration system is described in
|
|
||||||
.Xr autoconf 4 .
|
|
||||||
A list of the supported devices is given below.
