.Sh DESCRIPTION
When

on which it is running
and locates controllers, drives, and other devices, printing out
what it finds on the console. This procedure is driven by a system
configuration table which is processed by
.Xr config 8
and compiled into each kernel.
Devices which exist in the machine but are not configured into the
kernel are not detected.
.Sh DIAGNOSTICS

You tried to boot a

.Sh NAME
.Nm clmpcc
.Nd Cirrus Logic CD2400/CD2401 Communications Controller
.Sh SYNOPSIS
.Cd "clmpcc0 at pcctwo? ipl 4"
.Pp
.Sh DESCRIPTION
The
.Nm
driver provides support for the Cirrus Logic CD2401 Multi-protocol
Communications Controller found on Motorola MVME167 and MVME177
single-board computers.
.Pp
The chip integrates four serial channels in one package,
with each channel being completely independent and capable of
running in Async (with optional DMA control), Bisync, HDLC/SDLC and
X.21 modes. Each channel has 32 bytes of FIFO, split into 16 bytes
for the Tx side and 16 bytes for the Rx side.
.Pp
At the present time, the
.Nm
driver supports the non-DMA Async mode of operation, utilising the
channel FIFOs to maximize throughput with minimal interrupt overhead.
.Pp
The Motorola MVME1x7 boards provide a 20MHz master clock to the device,
which allows the Tx and Rx side to be independently set to any
baud rate in the range 50 to 57600.
The device should be capable of running at
a baud rate of 115200, however it is not a rate documented in the
device's datasheet for Async. mode so is not recommended.

.Sh SYNOPSIS
.Cd "clock0 at pcc? ipl 5"

.Sh DESCRIPTION
The

.Nm pcctwo
driver to provide two independent hardware clocks for use by the

.Sh NAME
.Nm intro
.Nd introduction to special files and hardware support
.Sh DESCRIPTION
This section describes the special files, related driver functions,
and networking support
available in the system.
In this part of the manual, the
.Tn SYNOPSIS
section of
each configurable device gives a sample specification
for use in constructing a system description for the
.Xr config 8
program.
The
.Tn 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 MVME68K DEVICE SUPPORT
This section describes the hardware supported on the
.Tn Motorola
MVME68K series of single board computers .
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 .
A list of the supported devices is given below.
.Sh LIST OF DEVICES
The devices listed below are supported in this incarnation of
the system.
Devices are indicated by their functional interface.

.Sh DESCRIPTION
The file
.Nm /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
.Nm /dev/mem .
.Pp
Kernel virtual memory is accessed via the file
.Nm /dev/kmem
in the same manner as
.Nm /dev/mem .
Only kernel virtual addresses that are currently mapped to memory are allowed.
.Pp
On the
.Tn Motorola
MVME series of single board computers,
physical memory may be discontiguous;
kernel virtual memory begins at
.Ad 0x00008000 .

.Sh SYNOPSIS
.Cd "ncrsc0 at pcctwo? ipl 2"
.Sh DESCRIPTION
The
.Nm
driver provides an abstraction layer between the SCSI hardware
fitted to
.Tn Motorola
MVME167 and MVME177 single board computers (NCR73C710),
and the machine independent SCSI drivers described in
.Xr scsibus 4 .
.Pp
In addition to sending the required SCSI commands to
target devices on the SCSI bus, the
.Nm
driver deals with DMA, device interrupts, sync/async negotiation
and target disconnects/reconnects.
.Sh DIAGNOSTICS
Too many to mention!
.Sh SEE ALSO
.Xr scsibus 4 ,
.Xr pcctwo 4
.Sh BUGS
The current
.Nm
driver should be obsoleted and replaced with a machine independent
version.

Negotiation of Synchronous SCSI data transfers has been
deliberately disabled in the MVME147's
.Nm
driver as it has proved extremely difficult to make it
work reliably in this mode.
.Pp
The
.Nm
driver does not respond well to exceptional conditions
caused by poor SCSI cabling and/or termination. In those
instances the machine is likely to require a hard reset
to recover.
.Pp
The current
.Nm
driver should be blown away and replaced with a machine independent
version.
