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 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 landisk 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
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. Not all supported devices are listed.
- ATAPI and SCSI CD-ROM driver
- landisk onboard I/O bus device
- PCI IDE controller driver
- power switch
- SCSI disk driver
- landisk SuperH PCI-Host Bridge
- WD100x compatible hard disk driver
- WD100x compatible hard disk controller driver
A further list of available devices is contained within the pages
describing the system buses and controllers. For example, a PCI device would
be listed in the pci(4) man page. The
following buses and controllers list these devices:
- 1-Wire bus
- introduction to PCI bus support
- introduction to Universal Serial Bus support
