.Sh NAME
|
||||
.Nm intro
|
||||
.Nd introduction to special files and hardware support
|
||||
.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 on the SPARC
|
||||
platform.
|
||||
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.

.Sh SUPPORTED SYSTEMS
|
||||
The following Sun SPARC system architectures and models are supported:
|
||||
.Bl -tag -width speaker
|
||||
.It sun4
|
||||
first generation SPARC systems on VMEbus:
|
||||
.br
|
||||
Sun 4/100 series (14.28 MHz)
|
||||
.br
|
||||
Sun 4/200 series (16.67 MHz)
|
||||
.br
|
||||
Sun 4/300 series (25 MHz)
|
||||
.br
|
||||
Sun 4/400 series (33 MHz)
|
||||
.It sun4c
|
||||
desktop SPARC systems with Sbus:
|
||||
.br
|
||||
SPARCstation 1 (20 MHz)
|
||||
.br
|
||||
SPARCstation 1+ (25 MHz)
|
||||
.br
|
||||
SPARCstation 2 (40 MHz)
|
||||
.br
|
||||
SPARCstation SLC (20 MHz)
|
||||
.br
|
||||
SPARCstation ELC (33 MHz)
|
||||
.br
|
||||
SPARCstation IPC (25 MHz)
|
||||
.br
|
||||
SPARCstation IPX (40 MHz).
|
||||
.It sun4m
|
||||
desktop SPARC systems with Mbus for CPUs, and Sbus:
|
||||
.br
|
||||
SPARC Classic (50 Mhz microSPARC I)
|
||||
.br
|
||||
SPARC LX (50 MHz microSPARC I)
|
||||
.br
|
||||
SPARCstation 4 (70 Mhz microSPARC II)
|
||||
.br
|
||||
SPARCstation 5 (70, 85, 110 MHz microSPARC II)
|
||||
.br
|
||||
SPARCstation 5 (170 MHz TurboSPARC)
|
||||
.br
|
||||
SPARCstation 10M (36 MHz SuperSPARC I)
|
||||
.br
|
||||
SPARCstation 20M (50 MHz SuperSPARC I)
|
||||
.br
|
||||
SPARCstation 10 (Mbus modules)
|
||||
.br
|
||||
SPARCstation 20 (Mbus modules)
|
||||
.El
|
||||
.Pp
|
||||
The SPARCstation 2 and IPX can be upgraded with a Weitek PowerUP CPU
|
||||
that is clock-doubled (i.e. internally it runs at 80 MHz).
|
||||
.Nx
|
||||
supports this configuration.
|
||||
.Pp
|
||||
Hardware level clones of these systems from other manufacturers
|
||||
will likely work (e.g. Xerox, Tatung, Axil, Cycle);
|
||||
other systems which have a SPARC CPU but do not
|
||||
use Sun's hardware architecture (e.g. Solbourne) will likely not work.
|
||||
.Pp
|
||||
The sun4d (SPARC Center 1000, 1000E, and 2000),
|
||||
and sun4u (UltraSPARC) architectures are not yet supported.
|
||||
.Pp
|
||||
The sun4m architecture with Mbus modules for the CPUs is supported
|
||||
with the following modules with only one CPU:
|
||||
.Bl -tag -width speaker
|
||||
.It SM41
|
||||
40 Mhz SuperSPARC I with 1MB SuperCACHE
|
||||
.It SM51
|
||||
50 Mhz SuperSPARC I with 1MB SuperCACHE
|
||||
.It SM61
|
||||
60 Mhz SuperSPARC I with 1MB SuperCACHE
|
||||
.It SM71
|
||||
75 Mhz SuperSPARC II with 1MB SuperCACHE
|
||||
.El
|
||||
.Pp
|
||||
.Nx
|
||||
does not yet support multiprocessor systems.
|
||||
