.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)
|
|
.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 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

|
|
.It HS11
|
|
100 Mhz Ross Technology HyperSPARC
|
|
.It HS21
|
|
125 Mhz Ross Technology HyperSPARC
|
|
.It M151
|
|
150 Mhz Ross Technology HyperSPARC
|
|
.El
|
|
.Pp
|
|
This list is not exhaustive;
|
|
.Nx
|
|
is continuously being improved, and may well run on Mbus CPU modules
|
|
not listed here.
|
|
.Pp
|
|
There is also some support for Sun
|
|
.Tn JavaStation
|
|
computers based on the microSPARC CPU.
|
|
.Pp
|
|
.Nx
|
|
does not yet properly support multiprocessor systems,
|
|
but will run on one processor of a multiprocessor system.
|
|
.Pp
|
|
The Sun 4/400 series, and sun4d (SPARC Center 1000, 1000E, and
|
|
2000) are not supported.
|
|
.Pp
|
|
The sun4u (UltraSPARC 64-bit) architectures are supported by
|
|
.Nx Ns Tn /sparc64 .
|
