NAME
intro_pmppc —
introduction to pmppc
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).
PMPPC DEVICE SUPPORT
This section describes the hardware supported on the Artesyn PM/PPC card.
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
autoconf(4). A list of the
supported devices is given below.
