INTRO(4)             NetBSD/x68k Kernel Interfaces Manual             INTRO(4)


NAME

     intro - introduction to x68k 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 specifi-
     cation for use in constructing a system description for the config(8)
     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 sys-
     tem and network related information.  The networking support is intro-
     duced in netintro(4).

X68k DEVICE SUPPORT
     This section describes the hardware supported on the x68k 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 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.
