NAME
intro —
introduction to sparc special
files and hardware support
DESCRIPTION
This section describes the special files, related driver functions, and
networking support available in the system. In this part of the manual, the
SYNOPSIS section of each configurable device gives a sample specification for
use in constructing a system description for the
config(1) program. The
DIAGNOSTICS section lists messages which may appear on the console and/or in
the system error log
/var/log/messages due to errors in
device operation; see
syslogd(8) for more
information.
This section contains both devices which may be configured into the system and
network related information. The networking support is introduced in
netintro(4).
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
device driver, or it may
be used within the networking subsystem and have a
network
interface driver. Block and character devices are accessed through files
in the file system of a special type; see
mknod(8). Network interfaces
are indirectly accessed through the interprocess communication facilities
provided by the system; see
socket(2).
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.
The autoconfiguration system is described in
sparc/autoconf(4). A
list of the supported devices is given below.

SUPPORTED SYSTEMS
The following Sun SPARC system architectures and models are supported:
-
-
- sun4
- first generation SPARC systems on VMEbus:
Sun 4/100 series (14.28 MHz)
Sun 4/200 series (16.67 MHz)
Sun 4/300 series (25 MHz)
-
-
- sun4c
- desktop SPARC systems with Sbus:
SPARCstation 1 (20 MHz)
SPARCstation 1+ (25 MHz)
SPARCstation 2 (40 MHz)
SPARCstation SLC (20 MHz)
SPARCstation ELC (33 MHz)
SPARCstation IPC (25 MHz)
SPARCstation IPX (40 MHz).
-
-
- sun4m
- desktop SPARC systems with Mbus for CPUs, and Sbus:
SPARCclassic (50 MHz microSPARC I)
SPARCstation LX (50 MHz microSPARC I)
SPARCstation 4 (70 MHz microSPARC II)
SPARCstation 5 (70, 85, 110 MHz microSPARC II)
SPARCstation 5 (170 MHz TurboSPARC)
SPARCstation 10M (36 MHz SuperSPARC I)
SPARCstation 20M (50 MHz SuperSPARC I)
SPARCstation 10 (Mbus modules)
SPARCstation 20 (Mbus modules)
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).
NetBSD supports this configuration.
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.
The sun4m architecture with Mbus modules for the CPUs is supported with the
following modules with only one CPU:
-
-
- SM41
- 40 MHz SuperSPARC I with 1MB SuperCACHE
-
-
- SM51
- 50 MHz SuperSPARC I with 1MB SuperCACHE
-
-
- SM61
- 60 MHz SuperSPARC I with 1MB SuperCACHE
-
-
- SM71
- 75 MHz SuperSPARC II with 1MB SuperCACHE
-
-
- SM81
- 85 MHz SuperSPARC II with 1MB SuperCACHE
-
-
- HS11
- 100 MHz Ross Technology hyperSPARC
-
-
- HS21
- 125 MHz Ross Technology hyperSPARC
-
-
- M151
- 150 MHz Ross Technology hyperSPARC
This list is not exhaustive;
NetBSD is continuously
being improved, and may well run on Mbus CPU modules not listed here.
There is also some support for Sun JavaStation computers based on the microSPARC
CPU.
NetBSD does not yet properly support multiprocessor
systems, but will run on one processor of a multiprocessor system.
The Sun 4/400 series, and sun4d (SPARCcenter 1000, 1000E, and 2000) are not
supported.
The sun4u (UltraSPARC 64-bit) architectures are supported by
NetBSD/sparc64.
