+on Loongson 2E-based systems, or the onboard memory and PCI-X controller
+found on Loongson 2F-based systems, which is a very close design, albeit
+not compatible with the original Bonito.
+.Pp
+Differences between the two models of controllers are hidden at the

+.Sh NAME
+.Nm intro
+.Nd introduction to special files and hardware support
+.Sh DESCRIPTION
+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
+.Sx SYNOPSIS
+section of
+each configurable device gives a sample specification
+for use in constructing a system description for the
+.Xr config 8
+program.
+The
+.Sx DIAGNOSTICS
+section lists messages which may appear on the console
+and/or in the system error log
+.Pa /var/log/messages
+due to errors in device operation;
+see
+.Xr syslogd 8
+for more information.
+.Pp
+This section contains both devices
+which may be configured into the system
+and network related information.
+The networking support is introduced in
+.Xr netintro 4 .
+.Sh DEVICE SUPPORT
+This section describes the hardware supported on the
+loongson platform.
+Software support for these devices comes in two forms.
+A hardware device may be supported with a character or block
+.Em device driver ,
+or it may be used within the networking subsystem and have a
+.Em network interface driver .
+Block and character devices are accessed through files in the file
+system of a special type; see
+.Xr mknod 8 .
+Network interfaces are indirectly accessed through the interprocess
+communication facilities provided by the system; see
+.Xr socket 2 .
+.Pp
+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.
+.Pp
+The autoconfiguration system is described in
+.Xr autoconf 4 .
+.Sh LIST OF DEVICES
+A complete 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
+.Xr pci 4
+man page.
+The following buses and controllers list these devices:

+.Nd memory files
+.Sh DESCRIPTION
+The file
+.Pa /dev/mem
+is an interface to the physical memory of the
+computer.
+Byte offsets in this file are interpreted as physical memory addresses.
+Reading and writing this file is equivalent to reading and writing
+memory itself.
+An error will be returned if an attempt is made to reference
+an offset outside of
+.Pa /dev/mem .
+.Pp
+Kernel virtual memory is accessed via the file
+.Pa /dev/kmem
+in the same manner as
+.Pa /dev/mem .
+Only kernel virtual addresses that are currently mapped to memory are allowed.
+.Pp
+On the loongson, physical memory is always contiguous, but can be accessed
+from two distinct physical address windows:
+.Bl -bullet -compact
+.It 
+From address
+.Ad 0x00000000
+to
+.Ad 0x0fffffff ,
+the lowest 256 megabytes of memory.
+.It
+From address
+.Ad 0x80000000
+to
+.Ad 0xffffffff ,
+the whole memory, up to 2 gigabytes.
+.El
+This layout implies that a given memory location within the first 256
+megabytes may indifferently be addressed in the
+.Ad 0x00000000 -
+.Ad 0x0fffffff
+address range or the
+.Ad 0x80000000 -
+.Ad 0x8fffffff
+address range.
+.Pp
+The kernel virtual memory begins at address
+.Ad 0xc000000000000000 .
+.Pp
+Writeability of these devices is controlled by the system
