CDU31A/CDU33A Driver Info
-------------------------
Information on the Sony CDU31A/CDU33A CDROM driver for the Linux
kernel.
Corey Minyard (minyard@metronet.com)
Colossians 3:17
Crude Table of Contents
-----------------------
Setting Up the Hardware
Configuring the Kernel
Configuring as a Module
Driver Special Features
This device driver handles Sony CDU31A/CDU33A CDROM drives and
provides a complete block-level interface as well as an ioctl()
interface as specified in include/linux/cdrom.h). With this
interface, CDROMs can be accessed, standard audio CDs can be played
back normally, and CD audio information can be read off the drive.
Note that this will only work for CDU31A/CDU33A drives. Some vendors
market their drives as CDU31A compatible. They lie. Their drives are
really CDU31A hardware interface compatible (they can plug into the
same card). They are not software compatible.
Setting Up the Hardware
-----------------------
The CDU31A driver is unable to safely tell if an interface card is
present that it can use because the interface card does not announce
its presence in any way besides placing 4 I/O locations in memory. It
used to just probe memory and attempt commands, but Linus wisely asked
me to remove that because it could really screw up other hardware in
the system.
Because of this, you must tell the kernel where the drive interface
is, what interrupts are used, and possibly if you are on a PAS-16
soundcard.
If you have the Sony CDU31A/CDU33A drive interface card, the following
diagram will help you set it up. If you have another card, you are on
your own. You need to make sure that the I/O address and interrupt is
not used by another card in the system. You will need to know the I/O
address and interrupt you have set. Note that use of interrupts is
highly recommended, if possible, it really cuts down on CPU used.
Unfortunately, most soundcards do not support interrupts for their
CDROM interfaces. By default, the Sony interface card comes with
interrupts disabled.

JP1 sets the Base Address, using the following settings:
Address Pin 1 Pin 2
------- ----- -----
0x320 Short Short
0x330 Short Open
0x340 Open Short
0x360 Open Open
JP2 and JP3 configure the DMA channel; they must be set the same.
DMA Pin 1 Pin 2 Pin 3
--- ----- ----- -----
1 On Off On
2 Off On Off
3 Off Off On
JP4 Configures the IRQ:
IRQ Pin 1 Pin 2 Pin 3 Pin 4
--- ----- ----- ----- -----
3 Off Off On Off
4 Off Off* Off On
5 On Off Off Off
6 Off On Off Off
The documentation states to set this for interrupt
4, but I think that is a mistake.
Note that if you have another interface card, you will need to look at
the documentation to find the I/O base address. This is specified to
the SLCD.SYS driver for DOS with the /B: parameter, so you can look at
you DOS driver setup to find the address, if necessary.
Configuring the Kernel
----------------------
You must tell the kernel where the drive is at boot time. This can be
done at the Linux boot prompt, by using LILO, or by using Bootlin.
Note that this is no substitute for HOWTOs and LILO documentation, if
you are confused please read those for info on bootline configuration
and LILO.
At the linux boot prompt, press the ALT key and add the following line
after the boot name (you can let the kernel boot, it will tell you the
default boot name while booting):
cdu31a=<base address>,<interrupt>[,PAS]
The base address needs to have "0x" in front of it, since it is in
hex. For instance, to configure a drive at address 320 on interrupt 5,
use the following:
cdu31a=0x320,5
I use the following boot line:
cdu31a=0x1f88,0,PAS
because I have a PAS-16 which does not support interrupt for the
CDU31A interface.
Adding this as an append line at the beginning of the /etc/lilo.conf
file will set it for lilo configurations. I have the following as the
first line in my lilo.conf file:
append="cdu31a=0x1f88,0"
I'm not sure how to set up Bootlin (I have never used it), if someone
would like to fill in this section please do.
Configuring as a Module
-----------------------
The driver supports loading as a module. However, you must specify
the boot address and interrupt on the boot line to insmod. You can't
use modprobe to load it, since modprobe doesn't support setting
variables.
Anyway, I use the following line to load my driver as a module
/sbin/insmod /lib/modules/`uname -r`/misc/cdu31a.o cdu31a_port=0x1f88
You can set the following variables in the driver:
cdu31a_port=<I/O address> - sets the base I/O. If hex, put 0x in
front of it. This must be specified.
cdu31a_irq=<interrupt> - Sets the interrupt number. Leaving this
off will turn interrupts off.
Driver Special Features
-----------------------
This section describes features beyond the normal audio and CD-ROM
functions of the drive.
2048 byte buffer mode
If a disk is mounted with -o block=2048, data is copied straight from
the drive data port to the buffer. Otherwise, the readahead buffer
must be involved to hold the other 1K of data when a 1K block
operation is done. Note that with 2048 byte blocks you cannot execute
files from the CD.
XA compatibility
The driver should support XA disks for both the CDU31A and CDU33A. It
does this transparently, the using program doesn't need to set it.
Multi-Session
A multi-session disk looks just like a normal disk to the user. Just
mount one normally, and all the data should be there. A special
thanks to Koen for help with this!
Raw sector I/O
Using the CDROMREADAUDIO it is possible to read raw audio and data
tracks. Both operations return 2352 bytes per sector. On the data
tracks, the first 12 bytes is not returned by the drive and the value
of that data is indeterminate.

This is the readme file for the driver for the Philips/LMS cdrom drive
cm206 in combination with the cm260 host adapter card.
(c) 1995 David A. van Leeuwen
Changes since version 0.99
--------------------------
- Interfacing to the kernel is routed though an extra interface layer,
cdrom.c. This allows runtime-configurable `behavior' of the cdrom-drive,
independent of the driver.
Features since version 0.33
---------------------------
- Full audio support, that is, both workman, workbone and cdp work
now reasonably. Reading TOC still takes some time. xmcd has been
reported to run successfully.
- Made auto-probe code a little better, I hope
Features since version 0.28
---------------------------
- Full speed transfer rate (300 kB/s).
- Minimum kernel memory usage for buffering (less than 3 kB).
- Multisession support.
- Tray locking.
- Statistics of driver accessible to the user.
- Module support.
- Auto-probing of adapter card's base port and irq line,
also configurable at boot time or module load time.
Decide how you are going to use the driver. There are two
options:
(a) installing the driver as a resident part of the kernel
(b) compiling the driver as a loadable module
Further, you must decide if you are going to specify the base port
address and the interrupt request line of the adapter card cm260 as
boot options for (a), module parameters for (b), use automatic
probing of these values, or hard-wire your adaptor card's settings
into the source code. If you don't care, you can choose
autoprobing, which is the default. In that case you can move on to
the next step.
Compiling the kernel
--------------------
1) move to /usr/src/linux and do a
make config
If you have chosen option (a), answer yes to CONFIG_CM206 and
CONFIG_ISO9660_FS.
If you have chosen option (b), answer yes to CONFIG_MODVERSIONS
and no (!) to CONFIG_CM206 and CONFIG_ISO9660_FS.
2) then do a
make clean; make zImage; make modules
3) do the usual things to install a new image (backup the old one, run
`rdev -R zImage 1', copy the new image in place, run lilo). Might
be `make zlilo'.
Using the driver as a module
----------------------------
If you will only occasionally use the cd-rom driver, you can choose
option (b), install as a loadable module. You may have to re-compile
the module when you upgrade the kernel to a new version.
Since version 0.96, much of the functionality has been transferred to
a generic cdrom interface in the file cdrom.c. The module cm206.o
depends on cdrom.o. If the latter is not compiled into the kernel,
you must explicitly load it before cm206.o:
insmod /usr/src/linux/modules/cdrom.o
To install the module, you use the command, as root
insmod /usr/src/linux/modules/cm206.o
You can specify the base address on the command line as well as the irq
line to be used, e.g.
insmod /usr/src/linux/modules/cm206.o cm206=0x300,11
The order of base port and irq line doesn't matter; if you specify only
one, the other will have the value of the compiled-in default. You
may also have to install the file-system module `iso9660.o', if you
didn't compile that into the kernel.
Using the driver as part of the kernel
--------------------------------------
If you have chosen option (a), you can specify the base-port
address and irq on the lilo boot command line, e.g.:
LILO: linux cm206=0x340,11
This assumes that your linux kernel image keyword is `linux'.
If you specify either IRQ (3--11) or base port (0x300--0x370),
auto probing is turned off for both settings, thus setting the
other value to the compiled-in default.
Note that you can also put these parameters in the lilo configuration file:
# linux config
image = /vmlinuz
root = /dev/hda1
label = Linux
append = "cm206=0x340,11"
read-only
If module parameters and LILO config options don't work
-------------------------------------------------------
If autoprobing does not work, you can hard-wire the default values
of the base port address (CM206_BASE) and interrupt request line
(CM206_IRQ) into the file /usr/src/linux/drivers/cdrom/cm206.h. Change
the defines of CM206_IRQ and CM206_BASE.
Mounting the cdrom
------------------
1) Make sure that the right device is installed in /dev.
mknod /dev/cm206cd b 32 0
2) Make sure there is a mount point, e.g., /cdrom
mkdir /cdrom
3) mount using a command like this (run as root):
mount -rt iso9660 /dev/cm206cd /cdrom
4) For user-mounts, add a line in /etc/fstab
/dev/cm206cd /cdrom iso9660 ro,noauto,user
This will allow users to give the commands
mount /cdrom
umount /cdrom
If things don't work
--------------------
- Try to do a `dmesg' to find out if the driver said anything about
what is going wrong during the initialization.
- Try to do a `dd if=/dev/cm206cd | od -tc | less' to read from the
CD.
- Look in the /proc directory to see if `cm206' shows up under one of
`interrupts', `ioports', `devices' or `modules' (if applicable).
DISCLAIMER
----------
I cannot guarantee that this driver works, or that the hardware will
not be harmed, although I consider it most unlikely.
I hope that you'll find this driver in some way useful.

Goldstar R420 CD-Rom device driver README
For all kind of other information about the GoldStar R420 CDROM
and this Linux device driver see the WWW page:
http://linux.rz.fh-hannover.de/~raupach
If you are the editor of a Linux CD, you should
enable gscd.c within your boot floppy kernel. Please,
send me one of your CDs for free.
This current driver version 0.4a only supports reading data from the disk.
Currently we have no audio and no multisession or XA support.
The polling interface is used, no DMA.
Sometimes the GoldStar R420 is sold in a 'Reveal Multimedia Kit'. This kit's
drive interface is compatible, too.
Installation
------------
Change to '/usr/src/linux/drivers/cdrom' and edit the file 'gscd.h'. Insert
the i/o address of your interface card.
The default base address is 0x340. This will work for most applications.
Address selection is accomplished by jumpers PN801-1 to PN801-4 on the
GoldStar Interface Card.
Appropriate settings are: 0x300, 0x310, 0x320, 0x330, 0x340, 0x350, 0x360
0x370, 0x380, 0x390, 0x3A0, 0x3B0, 0x3C0, 0x3D0, 0x3E0, 0x3F0
Then go back to '/usr/src/linux/' and 'make config' to build the new
configuration for your kernel. If you want to use the GoldStar driver
like a module, don't select 'GoldStar CDROM support'. By the way, you
have to include the iso9660 filesystem.
Now start compiling the kernel with 'make zImage'.
If you want to use the driver as a module, you have to do 'make modules'
and 'make modules_install', additionally.
Install your new kernel as usual - maybe you do it with 'make zlilo'.
Before you can use the driver, you have to
mknod /dev/gscd0 b 16 0
to create the appropriate device file (you only need to do this once).
If you use modules, you can try to insert the driver.
Say: 'insmod /usr/src/linux/modules/gscd.o'
or: 'insmod /usr/src/linux/modules/gscd.o gscd=<address>'
The driver should report its results.
That's it! Mount a disk, i.e. 'mount -rt iso9660 /dev/gscd0 /cdrom'
Feel free to report errors and suggestions to the following address.
Be sure, I'm very happy to receive your comments!

Docs by Eric van der Maarel <H.T.M.v.d.Maarel@marin.nl>
This is the README for version 0.6 of the cdrom interface on an
ISP16, MAD16 or Mozart sound card.
The detection and configuration of this interface used to be included
in both the sjcd and optcd cdrom driver. Drives supported by these
drivers came packed with Media Magic's multi media kit, which also
included the ISP16 card. The idea (thanks Leo Spiekman)
to move it from these drivers into a separate module and moreover, not to
rely on the MAD16 sound driver, are as follows:
-duplication of code in the kernel is a waste of resources and should
be avoided;
-however, kernels and notably those included with Linux distributions
(cf Slackware 3.0 included version 0.5 of the isp16 configuration
code included in the drivers) don't always come with sound support
included. Especially when they already include a bunch of cdrom drivers.
Hence, the cdrom interface should be configurable _independently_ of
sound support.
The ISP16, MAD16 and Mozart sound cards have an OPTi 82C928 or an
OPTi 82C929 chip. The interface on these cards should work with
any cdrom attached to the card, which is 'electrically' compatible
with Sanyo/Panasonic, Sony or Mitsumi non-ide drives. However, the
command sets for any proprietary drives may differ
(and hence may not be supported in the kernel) from these four types.
For a fact I know the interface works and the way of configuration
as described in this documentation works in combination with the
sjcd (in Sanyo/Panasonic compatibility mode) cdrom drivers
(probably with the optcd (in Sony compatibility mode) as well).
If you have such an OPTi based sound card and you want to use the
cdrom interface with a cdrom drive supported by any of the other cdrom
drivers, it will probably work. Please let me know any experience you
might have).
I understand that cards based on the OPTi 82C929 chips may be configured
(hardware jumpers that is) as an IDE interface. Initialisation of such a
card in this mode is not supported (yet?).
The suggestion to configure the ISP16 etc. sound card by booting DOS and
do a warm reboot to boot Linux somehow doesn't work, at least not
on my machine (IPC P90), with the OPTi 82C928 based card.
Booting the kernel through the boot manager LILO allows the use
of some command line options on the 'LILO boot:' prompt. At boot time
press Alt or Shift while the LILO prompt is written on the screen and enter
any kernel options. Alternatively these options may be used in
the appropriate section in /etc/lilo.conf. Adding 'append="<cmd_line_options>"'
will do the trick as well.
The syntax of 'cmd_line_options' is
isp16=[<port>[,<irq>[,<dma>]]][[,]<drive_type>]
If there is no ISP16 or compatibles detected, there's probably no harm done.
These options indicate the values that your cdrom drive has been (or will be)
configured to use.
Valid values for the base i/o address are:
port=0x340,0x320,0x330,0x360
for the interrupt request number
irq=0,3,5,7,9,10,11
for the direct memory access line
dma=0,3,5,6,7
and for the type of drive
drive_type=noisp16,Sanyo,Panasonic,Sony,Mitsumi.
Note that these options are case sensitive.
The values 0 for irq and dma indicate that they are not used, and
the drive will be used in 'polling' mode. The values 5 and 7 for irq
should be avoided in order to avoid any conflicts with optional
sound card configuration.
The syntax of the command line does not allow the specification of
irq when there's nothing specified for the base address and no
specification of dma when there is no specification of irq.
The value 'noisp16' for drive_type, which may be used as the first
non-integer option value (e.g. 'isp16=noisp16'), makes sure that probing
for and subsequent configuration of an ISP16-compatible card is skipped
all together. This can be useful to overcome possible conflicts which
may arise while the kernel is probing your hardware.
The default values are
port=0x340
irq=0
dma=0
drive_type=Sanyo
reflecting my own configuration. The defaults can be changed in
the file linux/drivers/cdrom/ips16.h.
The cdrom interface can be configured at run time by loading the
initialisation driver as a module. In that case, the interface
parameters can be set by giving appropriate values on the command
line. Configuring the driver can then be done by the following
command (assuming you have iso16.o installed in a proper place):
insmod isp16.o isp16_cdrom_base=<port> isp16_cdrom_irq=<irq> \
isp16_cdrom_dma=<dma> isp16_cdrom_type=<drive_type>
where port, irq, dma and drive_type can have any of the values mentioned
above.
Have fun!

If you are using the driver as a module, you can specify your ports and IRQs
like
# insmod mcdx.o mcdx=0x300,11,0x304,5
and so on ("address,IRQ" pairs).
This will override the configuration in mcdx.h.
This driver:
o handles XA and (hopefully) multi session CDs as well as
ordinary CDs;
o supports up to 5 drives (of course, you'll need free
IRQs, i/o ports and slots);
o plays audio
This version doesn't support yet:
o shared IRQs (but it seems to be possible - I've successfully
connected two drives to the same irq. So it's `only' a
problem of the driver.)
This driver never will:
o Read digital audio (i.e. copy directly), due to missing
hardware features.

This is the README file for the Optics Storage 8000 AT CDROM device driver.
This is the driver for the so-called 'DOLPHIN' drive, with the 34-pin
Sony-compatible interface. For the IDE-compatible Optics Storage 8001
drive, you will want the ATAPI CDROM driver. The driver also seems to
work with the Lasermate CR328A. If you have a drive that works with
this driver, and that doesn't report itself as DOLPHIN, please drop me
a mail.
The support for multisession CDs is in ALPHA stage. If you use it,
please mail me your experiences. Multisession support can be disabled
at compile time.
You can find some older versions of the driver at
dutette.et.tudelft.nl:/pub/linux/
and at Eberhard's mirror
ftp.gwdg.de:/pub/linux/cdrom/drivers/optics/
Before you can use the driver, you have to create the device file once:
# mknod /dev/optcd0 b 17 0
To specify the base address if the driver is "compiled-in" to your kernel,
you can use the kernel command line item (LILO option)
optcd=0x340
with the right address.
If you have compiled optcd as a module, you can load it with
# insmod /usr/src/linux/modules/optcd.o
or
# insmod /usr/src/linux/modules/optcd.o optcd=0x340
with the matching address value of your interface card.
The driver employs a number of buffers to do read-ahead and block size
conversion. The number of buffers is configurable in optcd.h, and has
influence on the driver performance. For my machine (a P75), 6 buffers
seems optimal, as can be seen from this table:
#bufs kb/s %cpu
1 97 0.1
2 191 0.3
3 188 0.2
4 246 0.3
5 189 19
6 280 0.4
7 281 7.0
8 246 2.8
16 281 3.4
If you get a throughput significantly below 300 kb/s, try tweaking
N_BUFS, and don't forget to mail me your results!
I'd appreciate success/failure reports. If you find a bug, try
recompiling the driver with some strategically chosen debug options
(these can be found in optcd.h) and include the messages generated in
your bug report. Good luck.

20% of the work takes 80% of the time...
(Murphy's law)
Once started, training can not be stopped...
(Star Wars)
This is the README for the sjcd cdrom driver, version 1.6.
This file is meant as a tips & tricks edge for the usage of the SANYO CDR-H94A
cdrom drive. It will grow as the questions arise. ;-)
For info on configuring the ISP16 sound card look at Documentation/cdrom/isp16.
The driver should work with any of the Panasonic, Sony or Mitsumi style
CDROM interfaces.
The cdrom interface on Media Magic's soft configurable sound card ISP16,
which used to be included in the driver, is now supported in a separate module.
This initialisation module will probably also work with other interfaces
based on an OPTi 82C928 or 82C929 chip (like MAD16 and Mozart): see the
documentation Documentation/cdrom/isp16.
The device major for sjcd is 18, and minor is 0. Create a block special
file in your /dev directory (e.g., /dev/sjcd) with these numbers.
(For those who don't know, being root and doing the following should do
the trick:
mknod -m 644 /dev/sjcd b 18 0
and mount the cdrom by /dev/sjcd).
The default configuration parameters are:
base address 0x340
no irq
no dma
(Actually the CDR-H94A doesn't know how to use irq and dma.)
As of version 1.2, setting base address at boot time is supported
through the use of command line options: type at the "boot:" prompt:
linux sjcd=<base_address>
(where you would use the kernel labeled "linux" in lilo's configuration
file /etc/lilo.conf). You could also use 'append="sjcd=<configuration_info>"'
in the appropriate section of /etc/lilo.conf
If you're building a kernel yourself you can set your default base
i/o address with SJCD_BASE_ADDR in /usr/src/linux/drivers/cdrom/sjcd.h.
The sjcd driver supports being loaded as a module. The following
command will set the base i/o address on the fly (assuming you
have installed the module in an appropriate place).
insmod sjcd.o sjcd_base=<base_address>

README FOR LINUX SONY CDU-535/531 DRIVER
========================================
This is the Sony CDU-535 (and 531) driver version 0.7 for Linux.
I do not think I have the documentation to add features like DMA support
so if anyone else wants to pursue it or help me with it, please do.
(I need to see what was done for the CDU-31A driver -- perhaps I can
steal some of that code.)
This is a Linux device driver for the Sony CDU-535 CDROM drive. This is
one of the older Sony drives with its own interface card (Sony bus).
The DOS driver for this drive is named SONY_CDU.SYS - when you boot DOS
your drive should be identified as a SONY CDU-535. The driver works
with a CDU-531 also. One user reported that the driver worked on drives
OEM'ed by Procomm, drive and interface board were labelled Procomm.
The Linux driver is based on Corey Minyard's sonycd 0.3 driver for
the CDU-31A. Ron Jeppesen just changed the commands that were sent
to the drive to correspond to the CDU-535 commands and registers.
There were enough changes to let bugs creep in but it seems to be stable.
Ron was able to tar an entire CDROM (should read all blocks) and built
ghostview and xfig off Walnut Creek's X11R5/GNU CDROM. xcdplayer and
workman work with the driver. Others have used the driver without
problems except those dealing with wait loops (fixed in third release).
Like Minyard's original driver this one uses a polled interface (this
is also the default setup for the DOS driver). It has not been tried
with interrupts or DMA enabled on the board.
REQUIREMENTS
============
- Sony CDU-535 drive, preferably without interrupts and DMA
enabled on the card.
- Drive must be set up as unit 1. Only the first unit will be
recognized
- You must enter your interface address into
/usr/src/linux/drivers/cdrom/sonycd535.h and build the
appropriate kernel or use the "kernel command line" parameter
sonycd535=0x320
with the correct interface address.
NOTES:
======
1) The drive MUST be turned on when booting or it will not be recognized!
(but see comments on modularized version below)
2) when the cdrom device is opened the eject button is disabled to keep the
user from ejecting a mounted disk and replacing it with another.
Unfortunately xcdplayer and workman also open the cdrom device so you
have to use the eject button in the software. Keep this in mind if your
cdrom player refuses to give up its disk -- exit workman or xcdplayer, or
umount the drive if it has been mounted.
THANKS
======
Many thanks to Ron Jeppesen (ronj.an@site007.saic.com) for getting
this project off the ground. He wrote the initial release
and the first two patches to this driver (0.1, 0.2, and 0.3).
Thanks also to Eberhard Moenkeberg (emoenke@gwdg.de) for prodding
me to place this code into the mainstream Linux source tree
(as of Linux version 1.1.91), as well as some patches to make
it a better device citizen. Further thanks to Joel Katz
<joelkatz@webchat.org> for his MODULE patches (see details below),
Porfiri Claudio <C.Porfiri@nisms.tei.ericsson.se> for patches
to make the driver work with the older CDU-510/515 series, and
Heiko Eissfeldt <heiko@colossus.escape.de> for pointing out that
the verify_area() checks were ignoring the results of said checks
(note: verify_area() has since been replaced by access_ok()).
(Acknowledgments from Ron Jeppesen in the 0.3 release:)
Thanks to Corey Minyard who wrote the original CDU-31A driver on which
this driver is based. Thanks to Ken Pizzini and Bob Blair who provided
patches and feedback on the first release of this driver.

------------------------------------------------------------------------------
(The following is from Joel Katz <joelkatz@webchat.org>.)
To build a version of sony535.o that can be installed as a module,
use the following command:
gcc -c -D__KERNEL__ -DMODULE -O2 sonycd535.c -o sonycd535.o
To install the module, simply type:
insmod sony535.o
or
insmod sony535.o sonycd535=<address>
And to remove it:
rmmod sony535
The code checks to see if MODULE is defined and behaves as it used
to if MODULE is not defined. That means your patched file should behave
exactly as it used to if compiled into the kernel.
I have an external drive, and I usually leave it powered off. I used
to have to reboot if I needed to use the CDROM drive. Now I don't.
Even if you have an internal drive, why waste the 96K of memory
(unswappable) that the driver uses if you use your CD-ROM drive infrequently?
This driver will not install (whether compiled in or loaded as a
module) if the CDROM drive is not available during its initialization. This
means that you can have the driver compiled into the kernel and still load
the module later (assuming the driver doesn't install itself during
power-on). This only wastes 12K when you boot with the CDROM drive off.
This is what I usually do; I leave the driver compiled into the
kernel, but load it as a module if I powered the system up with the drive
off and then later decided to use the CDROM drive.
Since the driver only uses a single page to point to the chunks,
attempting to set the buffer cache to more than 2 Megabytes would be very
bad; don't do that.

What is it ?
------------
This driver controls the BIONET-100 LAN-Adapter which connects
an ATARI ST/TT via the ACSI-port to an Ethernet-based network.
This version can be compiled as a loadable module (See the
compile command at the bottom of this file).
At load time, you can optionally set the debugging level and the
fastest response time on the command line of 'insmod'.
'bionet_debug'
controls the amount of diagnostic messages:
0 : no messages
>0 : see code for meaning of printed messages
'bionet_min_poll_time' (always >=1)
gives the time (in jiffies) between polls. Low values
increase the system load (beware!)
When loaded, a net device with the name 'bio0' becomes available,
which can be controlled with the usual 'ifconfig' command.
It is possible to compile this driver into the kernel like other
(net) drivers. For this purpose, some source files (e.g. config-files
makefiles, Space.c) must be changed accordingly. (You may refer to
other drivers how to do it.) In this case, the device will be detected
at boot time and (probably) appear as 'eth0'.
This code is based on several sources:
- The driver code for a parallel port ethernet adapter by
Donald Becker (see file 'atp.c' from the PC linux distribution)
- The ACSI code by Roman Hodek for the ATARI-ACSI harddisk support
and DMA handling.
- Very limited information about moving packets in and out of the
BIONET-adapter from the TCP package for TOS by BioData GmbH.
Theory of Operation
-------------------
Because the ATARI DMA port is usually shared between several
devices (eg. harddisk, floppy) we cannot block the ACSI bus
while waiting for interrupts. Therefore we use a polling mechanism
to fetch packets from the adapter. For the same reason, we send
packets without checking that the previous packet has been sent to
the LAN. We rely on the higher levels of the networking code to detect
missing packets and resend them.
Before we access the ATARI DMA controller, we check if another
process is using the DMA. If not, we lock the DMA, perform one or
more packet transfers and unlock the DMA before returning.
We do not use 'stdma_lock' unconditionally because it is unclear
if the networking code can be set to sleep, which will happen if
another (possibly slow) device is using the DMA controller.
The polling is done via timer interrupts which periodically
'simulate' an interrupt from the Ethernet adapter. The time (in jiffies)
between polls varies depending on an estimate of the net activity.
The allowed range is given by the variable 'bionet_min_poll_time'
for the lower (fastest) limit and the constant 'MAX_POLL_TIME'
for the higher (slowest) limit.
Whenever a packet arrives, we switch to fastest response by setting
the polling time to its lowest limit. If the following poll fails,
because no packets have arrived, we increase the time for the next
poll. When the net activity is low, the polling time effectively
stays at its maximum value, resulting in the lowest load for the
machine.
