introduction to luna68k 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(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).
This section describes the hardware supported on the luna68k 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 will have to be rebooted.
The autoconfiguration system is described in
luna68k/autoconf(4).
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.
