INTRO(4) NetBSD/dreamcast Kernel Interfaces Manual INTRO(4)
NAME
intro -- introduction to dreamcast 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(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 sys-
tem and network related information. The networking support is intro-
duced in netintro(4).
DEVICE SUPPORT
This section describes the hardware supported on the Dreamcast platform.
Software support for these devices come 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 must be rebooted.
The autoconfiguration system is described in autoconf(4). A list of the
supported devices is given below.
LIST OF DEVICES
The devices listed below are supported in this incarnation of the system.
Devices are indicated by their functional interface. Not all supported
devices are listed.
Standard builtin devices:
g2bus ``G2'' internal I/O bus
gapspci PCI bridge used in expansion port peripherals
gdrom Builtin GD-ROM optical disc drive
pvr Framebuffer device using the builtin NEC PVR graphics sub-
system
aica Builtin AICA sound system
Controller port peripherals are supported though the dreamcast/maple(4)
bus and associated device drivers.
Network interfaces:
rtk Ethernet driver for the HIT-0400 Broadband Adapter
mbe Ethernet driver for the HIT-0300 LAN Adapter
