INTRO(4) BSD Programmer's Manual (SPARC) INTRO(4)
intro - introduction to special files and hardware support
The manual pages in section 4 describe 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(8) program. The DIAGNOSTICS section lists messages which may ap-
pear 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 sys-
tem and network related information. The networking support is introduced
in netintro(4).
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 ac-
cessed 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 autoconfigura-
tion time it is not accessible at any time afterwards. To enable a device
which did not autoconfigure, the system will have to be rebooted.
The autoconfiguration system is described in autoconf(4). A list of the
supported devices is given below.
The devices listed below are supported in this incarnation of the system.
Pseudo-devices are not listed. Devices are indicated by their functional
interface. Not all supported devices are listed.
