1447673Scael.Sh DESCRIPTION
1530147SmckusickThis section describes the special files, related driver functions,
1630147Smckusickand networking support
1730147Smckusickavailable in the system.
1847673ScaelIn this part of the manual, the
1947673Scael.Tn SYNOPSIS
2047673Scaelsection of
2130147Smckusickeach configurable device gives a sample specification
2230147Smckusickfor use in constructing a system description for the
2347673Scael.Xr config 8
2430147Smckusickprogram.
2547673ScaelThe
2647673Scael.Tn DIAGNOSTICS
2747673Scaelsection lists messages which may appear on the console
2830147Smckusickand in the system error log
2947673Scael.Pa /var/log/messages
3030147Smckusickdue to errors in device operation.
3147673Scael.Sh CCI DEVICE SUPPORT
3247673ScaelSoftware support for these devices comes in two forms.  A hardware
3347673Scaeldevice may be supported with a character or block
3447673Scael.Em device driver ,
3547673Scaelor it may be used within the networking subsystem and have a
3647673Scael.Em network interface driver .
3747673ScaelBlock and character devices are accessed through files in the file
3847673Scaelsystem of a special type; see
3947673Scael.Xr physio 4
4047673Scaeland
4147673Scael.Xr mknod 8 .
4247673ScaelNetwork interfaces are indirectly accessed through the interprocess
4347673Scaelcommunication facilities provided by the system; see
4447673Scael.Xr socket 2 .
4547673Scael.Pp
4630147SmckusickA hardware device is identified to the system at configuration time
4730147Smckusickand the appropriate device or network interface driver is then compiled
4830147Smckusickinto the system.  When the resultant system is booted, the
4930147Smckusickautoconfiguration facilities in the system probe for the device
5047673Scaelon the
5147673Scael.Tn VERSAbus
5247673Scaeland, if found, enable the software
5347673Scaelsupport for it.  If a
5447673Scael.Tn VERSAbus
5547673Scaeldevice does not respond at autoconfiguration
5630147Smckusicktime it is not accessible at any time afterwards.  To
5747673Scaelenable a
5847673Scael.Tn VERSAbus
5947673Scaeldevice which did not autoconfigure, the system will have to
6030147Smckusickbe rebooted.
6147673Scael.Pp
6230147SmckusickThe autoconfiguration system is described in
6347673Scael.Xr autoconf 4 .

6930147SmckusickThe devices listed below are supported in this incarnation of
7030147Smckusickthe system.  Devices are indicated by their functional interface.
7130147SmckusickIf second vendor products provide functionally identical interfaces
7230147Smckusickthey should be usable with the supplied software.
