.Cd "device ace0 at vba? csr 0xffff0000 flags 0xfff80000 vector acecint acerint"
|
||||
.Sh DESCRIPTION
|
||||
The
|
||||
.Nm ace
|
||||
interface provides access to a 10 Mb/s Ethernet network through
|
||||
an
|
||||
.Tn ACC
|
||||
controller.
|
||||
.Pp
|
||||
The hardware has 32 kilobytes of dual-ported memory on the
|
||||
.Tn VERSAbus .
|
||||
This memory
|
||||
is used for internal buffering by the board, and the interface code reads
|
||||
the buffer contents directly through the
|
||||
.Tn VERSAbus .
|
||||
The address of this memory is given in the
|
||||
.Ar flags
|
||||
field
|
||||
in the configuration file.
|
||||
.Pp
|
||||
Each of the host's network addresses
|
||||
is specified at boot time with an
|
||||
.Dv SIOCSIFADDR
|
||||
.Xr ioctl 2 .
|
||||
The
|
||||
.Nm ace
|
||||
interface employs the address resolution protocol described in
|
||||
.Xr arp 4
|
||||
to dynamically map between Internet and Ethernet addresses on the local
|
||||
network.
|
||||
.Pp
|
||||
The interface normally tries to use a
|
||||
.Dq trailer
|
||||
encapsulation
|
||||
to minimize copying data on input and output.
|
||||
The use of trailers is negotiated with
|
||||
.Tn ARP .
|
||||
This negotiation may be disabled, on a per-interface basis,
|
||||
by setting the
|
||||
.Dv IFF_NOTRAILERS
|
||||
flag with an
|
||||
.Dv SIOCSIFFLAGS
|
||||
.Xr ioctl .
|
||||
.Pp
|
||||
The device implements an exponential backoff algorithm
|
||||
when notified of a collision on the cable. This algorithm utilizes
|
||||
a table of random numbers setup by the system at boot time.
|
||||
The delay is done in the controller.
|
||||
.Sh DIAGNOSTICS
|
||||
.Bl -diag
|
||||
.It "ace%d: stray xmit interrupt, xnct %d."
|
||||
An unexpected transmission complete interrupt was received;
|
||||
the interrupt is ignored.
|
||||
.It "ace%d: can't handle af%d."
|
||||
The interface was handed
|
||||
a message with addresses formatted in an unsuitable address
|
||||
family; the packet was dropped.

|
||||
.Sh BUGS
|
||||
The hardware is not capable of talking to itself. The software
|
||||
implements local sending and broadcast by sending such packets to the
|
||||
loop interface. This is a kludge.
|
||||
.Pp
|
||||
The device doesn't autoconfigure its interrupt vector; it is set
|
||||
at 0x90 + eight times the unit number.

.Sh DESCRIPTION
|
||||
When
|
||||
.Tn UNIX
|
||||
bootstraps it probes the innards of the machine it is running
|
||||
on 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.
|
||||
.Pp
|
||||
.Tn VERSAbus
|
||||
devices are located by probing to see if their control-status
|
||||
registers respond. If not, they are silently ignored. If the control
|
||||
status register responds but the device cannot be made to interrupt,
|
||||
a diagnostic warning will be printed on the console and the device
|
||||
will not be available to the system.
|
||||
.Pp
|
||||
A generic system may be built which picks its root device at boot time
|
||||
as the
|
||||
.Dq best
|
||||
available device.
|
||||
If such a system is booted with the
|
||||
.Dv RB_ASKNAME
|
||||
option of (see
|
||||
.Xr reboot 2 ) ,
|
||||
then the name of the root device is read from the console terminal at boot
|
||||
time, and any available device may be used.

The controller supports only 20-bit addresses. The only way the

system can insure the controller will be able to address data
|

to be transferred
|

is to copy it into an intermediate buffer allocated in the first megabyte

.Sh DESCRIPTION
|
||||
The

interface provides access to a 10 Mb/s Ethernet network through
|
||||
a
|
||||
.Tn CMC ENP-20
|
||||
controller.
|
||||
.Pp
|
||||
The hardware has 128 kilobytes of dual-ported memory on the
|
||||
.Tn VERSAbus .
|
||||
This memory
|
||||
is used for internal buffering by the board, and the interface code reads
|
||||
the buffer contents directly through the
|
||||
.Tn VERSAbus .
|
||||
The address of this memory is derived from the address specified
|
||||
in the configuration file.
|
||||
.Pp
|
||||
Each of the host's network addresses
|
||||
is specified at boot time with an
|
||||
.Dv SIOCSIFADDR
|
||||
.Xr ioctl 2 .
|
||||
The
|
||||
.Nm enp
|
||||
interface employs the address resolution protocol described in
|
||||
.Xr arp 4
|
||||
to dynamically map between Internet and Ethernet addresses on the local
|
||||
network.
|
||||
.Pp
|
||||
The interface normally tries to use a
|
||||
.Dq trailer
|
||||
encapsulation
|
||||
to minimize copying data on input and output.
|
||||
The use of trailers is negotiated with
|
||||
.Tn ARP .
|
||||
This negotiation may be disabled, on a per-interface basis,
|
||||
by setting the
|
||||
.Dv IFF_NOTRAILERS
|
||||
flag with an
|
||||
.Dv SIOCSIFFLAGS
|
||||
.Xr ioctl .
|
||||
.Pp
|
||||
Associated with each interface is a character device which
|
||||
is used to dowload, start, and reset the firmware in the controller.
|
||||
Reading or writing the
|
||||
.Dq ram device
|
||||
reads or writes the writable
|
||||
control store in the controller. Two
|
||||
.Xr ioctl 2
|
||||
calls,
|
||||
.Dv ENPIOGO
|
||||
and
|
||||
.Dv ENPIORESET ,

are used to start and reset the

The hardware is not capable of talking to itself. The software

implements local sending and broadcast by sending such packets to the

The driver currently supports only physical
|
||||
.Tn I/O operations
|
||||
when reading and writing; this makes the device useless with
|
||||
standard Evans and Sutherland software.
|
||||
.Pp
|
||||
The interface provided by the interface is as
|
||||
.Ux Ns -like
|
||||
as possible.
|
||||
When a device is opened a
|
||||
.Tn PS300
|
||||
attach request is automatically
|
||||
performed. When a device is closed a detach is performed. Reads
|
||||
and writes result in physical
|
||||
.Tn I/O
|
||||
requests, but hide all the details
|
||||
of the physical
|
||||
.Tn I/O
|
||||
protocol. This is programming style is completely
|
||||
different from the
|
||||
.Tn VMS Ns -oriented
|
||||
qio-style interface supplied by Evans
|
||||
and Sutherland.
|
||||
.Pp
|
||||
Reads and writes to the device result in a physical
|
||||
.Tn I/O
|
||||
request
|
||||
to the
|
||||
.Tn PS300 .
|
||||
If a
|
||||
.Xr readv 2
|
||||
or
|
||||
.Xr writev 2
|
||||
call is used, each
|
||||
.Tn I/O
|
||||
request results in a single physical
|
||||
.Tn I/O
|
||||
request (i.e. the scatter-gather facilities are not supported).
|
||||
In normal operation, the address used in a physical
|
||||
.Tn I/O
|
||||
request
|
||||
is the current file offset as specified explicitly with
|
||||
.Xr lseek 2
|
||||
or implictly as a result of reading or writing the device.
|
||||
To specify an address to be used with each physical
|
||||
.Tn I/O
|
||||
request,
|
||||
the
|
||||
.Nm ik
|
||||
driver interprets the
|
||||
.Ar iov
|
||||
entries in a non-standard way. If
|
||||
.Ar iov_len
|
||||
is zero, then
|
||||
.Ar iov_base
|
||||
is interpreted as an address to be used in the physical
|
||||
.Tn I/O
|
||||
request. If the address has the
|
||||
.Dv PSIO_SYNC
|
||||
flag or-d into it,
|
||||
the physical
|
||||
.Tn I/O
|
||||
request is made as a ``write with sync''.
|
||||
All addresses and data presented to the driver should be in
|
||||
the byte order of the host; any byte swapping required to converse
|
||||
with the
|
||||
.Tn PS300
|
||||
is performed in the driver/controller.
|
||||
.Pp
|
||||
In addition to reading and writing, the following
|
||||
.Xr ioctl
|
||||
requests are available:
|
||||
.Bl -tag -width PSIOGETERROR
|
||||
.It Dv PSIOLOOKUP
|
||||
Perform a ``name lookup'' request. The
|
||||
.Ar pslookup
|
||||
structure passed indicates the symbol name to be looked up
|
||||
and contains the address returned by the
|
||||
.Tn PS300 .
|
||||
A zero
|
||||
address return indicates the symbol was undefined.
|
||||
.It Dv PSIOGETERROR
|
||||
In the event of an error, this request may be made to
|
||||
return a more detailed and, sometimes
|
||||
.Tn PS300 Ns -specific ,

|
||||
.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 in the system error log
|
||||
.Pa /var/log/messages
|
||||
due to errors in device operation.
|
||||
.Sh CCI DEVICE SUPPORT
|
||||
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 physio 4
|
||||
and
|
||||
.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
|
||||
on the
|
||||
.Tn VERSAbus
|
||||
and, if found, enable the software
|
||||
support for it. If a
|
||||
.Tn VERSAbus
|
||||
device does not respond at autoconfiguration
|
||||
time it is not accessible at any time afterwards. To
|
||||
enable a
|
||||
.Tn VERSAbus
|
||||
device which did not autoconfigure, the system will have to
|
||||
be rebooted.
|
||||
.Pp
|
||||
The autoconfiguration system is described in
|
||||
.Xr autoconf 4 .

||||
The devices listed below are supported in this incarnation of
|

the system. Devices are indicated by their functional interface.
|
||||
If second vendor products provide functionally identical interfaces
|
||||
they should be usable with the supplied software.

.Sh DESCRIPTION
|
||||
The special 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.
|
||||
Only offsets within the bounds of
|
||||
.Nm /dev/mem
|
||||
are allowed.
|
||||
.Pp
|
||||
Kernel virtual memory is accessed through the interface
|
||||
.Nm /dev/kmem
|
||||
in the same manner as
|
||||
.Nm /dev/mem .
|
||||
Only kernel virtual addresses that are currently mapped to memory are allowed.
|
||||
.Pp
|
||||
The file
|
||||
.Nm /dev/vmem
|
||||
allows access to the mapped portion of the
|
||||
.Tn VERSAbus
|
||||
.Tn I/O
|
||||
space. On the Tahoe the upper megabyte
|
||||
of the physical address space is accessible through
|
||||
this file (0xfff00000 through 0xffffffff).
|
||||
Accesses to the upper 64 kilobytes of
|
||||
the
|
||||
.Tn I/O
|
||||
space result in
|
||||
.Tn VERSAbus
|
||||
transfers with a
|
||||
16-bit address (the offset in this region) and a
|
||||
.Dq No non-privileged short Tn I/O
|
||||
.Tn VERSAbus
|
||||
address modifier.
|
||||
Accesses to the remainder of the mapped region,
|
||||
result in
|
||||
.Tn VERSAbus
|
||||
transfers with a 24-bit address
|
||||
and a ``non-privileged standard''
|
||||
.Tn VERSAbus
|
||||
address
|
||||
modifier. This region is actually part of the region
|
||||
between 0xfeff0000 and 0xffff0000
|
||||
which generates
|
||||
.Tn VERSAbus
|
||||
transfers with a 24-bit address.
|
||||
Accesses to the remainder of the one gigabyte
|
||||
.Tn I/O
|
||||
space
|
||||
generate transfers that utilize a 32-bit address with
|
||||
a ``non-privileged extended'' address modifier. Any
|
||||
32-bit address generated by a cpu access to this part
|
||||
of the
|
||||
.Tn I/O
|
||||
space have the upper two bits zero; thus,
|
||||
for example, an access to physical address 0xfe000000
|
||||
causes the address 0x3e000000 to be supplied in the
|
||||
resultant
|
||||
.Tn VERSAbus
|
||||
read/write cycle.
|
||||
.Pp
|
||||
On the Tahoe, the
|
||||
base address for the
|
||||
per-process data of the current process
|
||||
is virtual address 0xbffff000.

.Cd "controller vd0 at vba? csr 0xffff2000 vector vdintr"

|
||||
.Sh DESCRIPTION
|
||||
This is a generic
|
||||
.Tn VERSAbus
|
||||
storage module disk driver for the
|
||||
Computer Consoles
|
||||
.Tn SMD
|
||||
.Pq Tn VDDC
|
||||
and
|
||||
.Tn SMD-E
|
||||
disk controllers.
|
||||
.Pp
|
||||
The
|
||||
.Nm vd
|
||||
driver is a fairly typical block
|
||||
.Tn I/O
|
||||
device, except
|
||||
raw block
|
||||
.Tn I/O
|
||||
counts must be a multiple of 1024 bytes,
|
||||
whether the actual sector size is 512 or 1024 bytes.
|
||||
Likewise,
|
||||
.Xr seek
|
||||
calls should specify a multiple of 1024 bytes.
|
||||
See
|
||||
.Xr physio 4 .
|
||||
.Pp
|
||||
The first sector of each disk contains a disk label
|
||||
containing geometry information and partition layouts (see
|
||||
.Xr disklabel 5 ) .
|
||||
This sector is normally write-protected, and disk-to-disk copies should
|
||||
avoid copying this sector.
|
||||
The label may be updated with
|
||||
.Xr disklabel 8 ,
|
||||
which can also be used to write-enable and write-disable the sector.
|
||||
.Sh DISK SUPPORT
|
||||
During autoconfiguration,
|
||||
as well as when a drive is opened after all partitions are closed,
|
||||
the first sector of the drive is examined for a disk label.
|
||||
If a label is found, the geometry of the drive and the partition tables
|
||||
are taken from it.
|
||||
If no label is found,
|
||||
The driver checks for a disk label on sector 0 of each drive
|
||||
during autoconfiguration.
|
||||
If no label is found,
|
||||
the driver tries to access the last track on each drive
|
||||
to determine the type of drive attached.
|
||||
The driver has default partition tables for
|
||||
seven different drives:
|
||||
.Tn CDC FSD
|
||||
(160
|
||||
.Tn MB ) ,
|
||||
.Tn CDC
|
||||
9766 (300
|
||||
.Tn MB ) ,
|
||||
.Tn CDC XFSD
|
||||
(340
|
||||
.Tn MB ) ,
|
||||
.Tn CDC
|
||||
515
|
||||
.Tn MB ,
|
||||
Fujitsu 360
|
||||
.Tn MB ,
|
||||
Fujitsu Eagle (440
|
||||
.Tn MB ) ,
|
||||
and Maxtor 340
|
||||
.Tn MB .
|
||||
If the drive is not recognized, a single small partition is created
|
||||
to allow a label to be written.
|
||||
.Pp
|
||||
The partition tables in the disk label and the
|
||||
.Pa disktab
|
||||
file specify partition offsets and sizes in sectors, which are 512 bytes
|
||||
on
|
||||
.Tn SMD
|
||||
drives and 1024 bytes on 5 1/4"
|
||||
.Tn ESDI
|
||||
drives.
|
||||
By convention,
|
||||
the ?a partition is normally used for the root file system or other small
|
||||
file system,
|
||||
and the ?b partition is used as a paging area.
|
||||
The ?c partition maps the rest of the pack,
|
||||
except the last 5 cylinders which are reserved for bad sector forwarding,
|
||||
and diagnostic use.

or
|
||||
.Tn SMDE .
|

.It vd%d: diagnostic error.
|
||||
During autoconfiguration the controller failed to respond to
|
||||
a diagnostic command.
|
||||
.Pp
|
||||
.It dk%d: unknown drive type.
|
||||
The system was unable to identify the specified drive as
|
||||
one of the drives described above; the drive will not be
|
||||
configured.
|
||||
.Pp
|
||||
.It vd%d: drive %d: config error.
|
||||
The system encountered a hard error when it tried to configure
|
||||
a drive during autoconfiguration.
|
||||
.Pp
|
||||
.It vd%d: starting drives, wait ... .
|
||||
This message indicates the system is about to tell the
|
||||
controller to ``start'' the drives attached to it.
|
||||
.Pp
|
||||
.It dk%d: %s <ntrak %d, ncyl %d, nsec %d>.
|
||||
For each drive recognized during autoconfiguration the system
|
||||
prints a message of this form. The drive type is displayed
|
||||
as well as the geometry: tracks/cylinder, cylinders, and sectors/track.
|
||||
.Pp
|
||||
.It vd%d: lost interrupt.
|
||||
The system failed to receive an interrupt from the controller after
|
||||
submitting a request.
|
||||
The system attempts to abort the current request and simulate an
|
||||
interrupt to unwedge the controller.
|
||||
During processing of the simulated interrupt, a controller error
|
||||
will be reported as described below.
|
||||
.Pp
|
||||
.It vd%d: stray interrupt.
|
||||
The system received an unexpected interrupt; it is ignored.
|
||||
.Pp
|
||||
.It dk%d%c: write locked.
|
||||
An attempt was made to write to a drive that is physically write-protected.
|
||||
.Pp
|
||||
.It "dk%d%c: controller err %sing fsbn %d [of %d-%d] (dk%d bn %d cn %d tn %d sn %d) status %b ecode %x; resetting controller... retrying."

|
||||
.It "dk%d%c: drive err %sing fsbn %d [of %d-%d] (dk%d bn %d cn %d tn %d sn %d) status %b ecode %x; resetting drive... retrying."
|
||||
An attempted transfer resulted in a controller or drive error.
|
||||
The controller or drive is reset, and the transfer is attempted
|
||||
a second time.
|
||||
.Pp
|
||||
.It "dk%d%c: hard error %sing fsbn %d [of %d-%d] (dk%d bn %d cn %d tn %d sn %d) status %b ecode %x."
|
||||
An unrecoverable error was encountered. The filesystem block number reported
|
||||
is a logical sector number on the indicated partition;
|
||||
it is expressed using 1024-byte sectors.
|
||||
If the transfer involved multiple blocks, the block range is printed as well.
|
||||
The parenthesized fields list the actual disk sector number
|
||||
relative to the beginning of the drive
|
||||
(in 512- or 1024-byte blocks, as appropriate),
|
||||
as well as the cylinder, track and sector number of the block.
|
||||
The error status field of the device control
|
||||
block is printed in hexadecimal followed by a symbolic description.
|
||||
If this is an
|
||||
.Tn SMDE
|
||||
controller, the error code is also displayed.
|
||||
.Pp
|
||||
.It "dk%d%c: soft error %sing fsbn %d [of %d-%d] (dk%d bn %d cn %d tn %d sn %d) status %b ecode %x."
|
||||
A recoverable error was detected by the controller.
|
||||
The fields are interpreted in the same way as those for hard errors.
|
||||
.Pp
|
||||
.It "dk%d%c: soft ecc %sing fsbn %d [of %d-%d] (dk%d bn %d cn %d tn %d sn %d)."
|
||||
A recoverable
|
||||
.Tn ECC
|
||||
error was detected and corrected by the controller
|
||||
during the indicated transfer.
|
||||
.Pp
|
||||
.It vd%d: drive %d: couldn't reset.
|
||||
The system was unable to reconfigure a drive during a controller reset.
|
||||
.Pp
|
||||
.It vd%d: controller timeout.
|
||||
The controller failed to complete an operation within a reasonable
|
||||
time. This message is usually followed by another message indicating
|
||||
what operation timed out; e.g. ``during config'' for a configuration
|
||||
command.

.It VIOC-BOP no. %d at %x.
|
||||
The system identified a vioc supporting the bit oriented protocol.
|
||||
The number
|
||||
.Em %d
|
||||
is the board number assigned by the system
|
||||
while the address
|
||||
.Em %x
|
||||
is the address of the command control
|
||||
block for the vioc.
|
||||
.It vx%d: unknown type %x.
|
||||
The system encountered a vioc of unknown type during autoconfiguration.
|
||||
.It vx%d: didn't respond to LIDENT.
|
||||
The device did not respond to the configuration command that
|
||||
sets the interrupt vectors and port configuration.
|
||||
.It vx%d: %s%s, ports %d-%d.
|
||||
This is informatory message printed during autoconfiguration
|
||||
indicating the type of hardware present the port configuration.
|
||||
.It vx%d: no buffers.
|
||||
All the command buffers were in use; this indicates the device
|
||||
is constipated for some reason.
|
||||
.It vx%d: setq overflow.
|
||||
An attempt to append a command to an existing command buffer
|
||||
failed because the buffer was full or the hardware doesn't
|
||||
support this facility.
|
||||
.It vx%d: cmd q overflow.
|
||||
An attempt to place a new command on the command queue failed
|
||||
because it was full. The device is either overloaded or hung
|
||||
up for some reason. If this happens, the system tries to
|
||||
reset the device to unwedge it.
|
||||
.It vx%d INTR ERR type %x v_dcd %x.
|
||||
An error was returned by the device in response to some command.
|
||||
The command identifier and data carrier detect mask are printed
|
||||
followed by the contents of the command buffer in error.
|
||||
.It vx%d: vcmdrsp interrupt.
|
||||
A command response interrupt was received from a bop (bit oriented
|
||||
protocol) vioc. This should not happen.
|
||||
.It vx%d: cmdresp debug.
|
||||
.Pp
|
||||
.It vx%d: vunsol from
|
||||
.Tn BOP .
|
||||
An unsolicited interrupt was received from a bop vioc. This should
|
||||
not happen.
|
||||
.It vx%d: interrupt q overflow.
|
||||
The queue of pending interrupts to be delivered to the vioc is
|
||||
full. This is probably due to the vioc being wedged. The system
|
||||
resets the vioc if this occurs.
|
||||
.It vx%d: reset....
|
||||
The system attempted to reset the vioc.
