-
-1. NOTE
-This software has been successfully in alpha and beta test and is part of
-the standard kernel since kernel 1.1.8x since December 1994. It works with
-AZTECH CDA268-01A, ORCHID CDS-3110, ORCHID/WEARNES CDD110 and CONRAD TXC
-(Nr.99 31 23 -series 04) and has proven to be stable with kernel
-versions 1.0.9 and newer. But with any software there still may be bugs in it.
-So if you encounter problems, you are invited to help us improve this software.
-Please send me a detailed bug report (see chapter BUG REPORTS). You are also
-invited in helping us to increase the number of drives, which are supported.
-
-Please read the README-files carefully and always keep a backup copy of your
-old kernel, in order to reboot if something goes wrong!
-
-2. INSTALLATION
-The driver consists of a header file 'aztcd.h', which normally should reside
-in /usr/src/linux/drivers/cdrom and the source code 'aztcd.c', which normally
-resides in the same place. It uses /dev/aztcd (/dev/aztcd0 in some distri-
-butions), which must be a valid block device with major number 29 and reside
-in directory /dev. To mount a CD-ROM, your kernel needs to have the ISO9660-
-filesystem support included.
-
-PLEASE NOTE: aztcd.c has been developed in parallel to the linux kernel,
-which had and is having many major and minor changes which are not backward
-compatible. Quite definitely aztcd.c version 1.80 and newer will NOT work
-in kernels older than 1.3.33. So please always use the most recent version
-of aztcd.c with the appropriate linux-kernel.
-
-3. CONFIGURING YOUR KERNEL
-If your kernel is already configured for using the AZTECH driver you will
-see the following message while Linux boots:
- Aztech CD-ROM Init: DriverVersion=<version number> BaseAddress=<baseaddress>
- Aztech CD-ROM Init: FirmwareVersion=<firmware version id of your I/O-card>>>
- Aztech CD-ROM Init: <drive type> detected
- Aztech CD-ROM Init: End
-If the message looks different and you are sure to have a supported drive,
-it may have a different base address. The Aztech driver does look for the
-CD-ROM drive at the base address specified in aztcd.h at compile time. This
-address can be overwritten by boot parameter aztcd=....You should reboot and
-start Linux with boot parameter aztcd=<base address>, e.g. aztcd=0x320. If
-you do not know the base address, start your PC with DOS and look at the boot
-message of your CD-ROM's DOS driver. If that still does not help, use boot
-parameter aztcd=<base address>,0x79 , this tells aztcd to try a little harder.
-aztcd may be configured to use autoprobing the base address by recompiling
-it (see chapter 4.).
-
-If the message looks correct, as user 'root' you should be able to mount the
-drive by
- mount -t iso9660 -r /dev/aztcd0 /mnt
-and use it as any other filesystem. (If this does not work, check if
-/dev/aztcd0 and /mnt do exist and create them, if necessary by doing
- mknod /dev/aztcd0 b 29 0
- mkdir /mnt
-
-If you still get a different message while Linux boots or when you get the
-message, that the ISO9660-filesystem is not supported by your kernel, when
-you try to mount the CD-ROM drive, you have to recompile your kernel.
-
-If you do *not* have an Aztech/Orchid/Okano/Wearnes/TXC drive and want to
-bypass drive detection during Linux boot up, start with boot parameter aztcd=0.
-
-Most distributions nowadays do contain a boot disk image containing aztcd.
-Please note, that this driver will not work with IDE/ATAPI drives! With these
-you must use ide-cd.c instead.
-
-4. RECOMPILING YOUR KERNEL
-If your kernel is not yet configured for the AZTECH driver and the ISO9660-
-filesystem, you have to recompile your kernel:
-
-- Edit aztcd.h to set the I/O-address to your I/O-Base address (AZT_BASE_ADDR),
- the driver does not use interrupts or DMA, so if you are using an AZTECH
- CD268, an ORCHID CD-3110 or ORCHID/WEARNES CDD110 that's the only item you
- have to set up. If you have a soundcard, read chapter 4.2.
- Users of other drives should read chapter OTHER DRIVES of this file.
- You also can configure that address by kernel boot parameter aztcd=...
-- aztcd may be configured to use autoprobing the base address by setting
- AZT_BASE_ADDR to '-1'. In that case aztcd probes the addresses listed
- under AZT_BASE_AUTO. But please remember, that autoprobing always may
- incorrectly influence other hardware components too!
-- There are some other points, which may be configured, e.g. auto-eject the
- CD when unmounting a drive, tray locking etc., see aztcd.h for details.
-- If you're using a linux kernel version prior to 2.1.0, in aztcd.h
- uncomment the line '#define AZT_KERNEL_PRIOR_2_1'
-- Build a new kernel, configure it for 'Aztech/Orchid/Okano/Wearnes support'
- (if you want aztcd to be part of the kernel). Do not configure it for
- 'Aztech... support', if you want to use aztcd as a run time loadable module.
- But in any case you must have the ISO9660-filesystem included in your
- kernel.
-- Activate the new kernel, normally this is done by running LILO (don't for-
- get to configure it before and to keep a copy of your old kernel in case
- something goes wrong!).
-- Reboot
-- If you've included aztcd in your kernel, you now should see during boot
- some messages like
- Aztech CD-ROM Init: DriverVersion=<version number> BaseAddress=<baseaddress>
- Aztech CD-ROM Init: FirmwareVersion=<firmware version id of your I/O-card>
- Aztech CD-ROM Init: <drive type> detected
- Aztech CD-ROM Init: End
-- If you have not included aztcd in your kernel, but want to load aztcd as a
- run time loadable module see 4.1.
-- If the message looks correct, as user 'root' you should be able to mount
- the drive by
- mount -t iso9660 -r /dev/aztcd0 /mnt
- and use it as any other filesystem. (If this does not work, check if
- /dev/aztcd0 and /mnt do exist and create them, if necessary by doing
- mknod /dev/aztcd0 b 29 0
- mkdir /mnt
-- If this still does not help, see chapters OTHER DRIVES and DEBUGGING.
-
-4.1 AZTCD AS A RUN-TIME LOADABLE MODULE
-If you do not need aztcd permanently, you can also load and remove the driver
-during runtime via insmod and rmmod. To build aztcd as a loadable module you
-must configure your kernel for AZTECH module support (answer 'm' when con-
-figuring the kernel). Anyhow, you may run into problems, if the version of
-your boot kernel is not the same than the source kernel version, from which
-you create the modules. So rebuild your kernel, if necessary.
-
-Now edit the base address of your AZTECH interface card in
-/usr/src/linux/drivers/cdrom/aztcd.h to the appropriate value.
-aztcd may be configured to use autoprobing the base address by setting
-AZT_BASE_ADDR to '-1'. In that case aztcd probes the addresses listed
-under AZT_BASE_AUTO. But please remember, that autoprobing always may
-incorrectly influence other hardware components too!
-There are also some special features which may be configured, e.g.
-auto-eject a CD when unmounting the drive etc; see aztcd.h for details.
-Then change to /usr/src/linux and do a
- make modules
- make modules_install
-After that you can run-time load the driver via
- insmod /lib/modules/X.X.X/misc/aztcd.o
-and remove it via rmmod aztcd.
-If you did not set the correct base address in aztcd.h, you can also supply the
-base address when loading the driver via
- insmod /lib/modules/X.X.X/misc/aztcd.o aztcd=<base address>
-Again specifying aztcd=-1 will cause autoprobing.
-If you do not have the iso9660-filesystem in your boot kernel, you also have
-to load it before you can mount the CDROM:
- insmod /lib/modules/X.X.X/fs/isofs.o
-The mount procedure works as described in 4. above.
-(In all commands 'X.X.X' is the current linux kernel version number)
-
-4.2 CDROM CONNECTED TO A SOUNDCARD
-Most soundcards do have a bus interface to the CDROM-drive. In many cases
-this soundcard needs to be configured, before the CDROM can be used. This
-configuration procedure consists of writing some kind of initialization
-data to the soundcard registers. The AZTECH-CDROM driver in the moment does
-only support one type of soundcard (SoundWave32). Users of other soundcards
-should try to boot DOS first and let their DOS drivers initialize the
-soundcard and CDROM, then warm boot (or use loadlin) their PC to start
-Linux.
-Support for the CDROM-interface of SoundWave32-soundcards is directly
-implemented in the AZTECH driver. Please edit linux/drivers/cdrom/aztdc.h,
-uncomment line '#define AZT_SW32' and set the appropriate value for
-AZT_BASE_ADDR and AZT_SW32_BASE_ADDR. This support was tested with an Orchid
-CDS-3110 connected to a SoundWave32.
-If you want your soundcard to be supported, find out, how it needs to be
-configured and mail me (see 6.) the appropriate information.
-
-5. KNOWN PROBLEMS, FUTURE DEVELOPMENTS
-5.1 MULTISESSION SUPPORT
-Multisession support for CD's still is a myth. I implemented and tested a basic
-support for multisession and XA CDs, but I still have not enough CDs and appli-
-cations to test it rigorously. So if you'd like to help me, please contact me
-(Email address see below). As of version 1.4 and newer you can enable the
-multisession support in aztcd.h by setting AZT_MULTISESSION to 1. Doing so
-will cause the ISO9660-filesystem to deal with multisession CDs, ie. redirect
-requests to the Table of Contents (TOC) information from the last session,
-which contains the info of all previous sessions etc.. If you do set
-AZT_MULTISESSION to 0, you can use multisession CDs anyway. In that case the
-drive's firmware will do automatic redirection. For the ISO9660-filesystem any
-multisession CD will then look like a 'normal' single session CD. But never-
-theless the data of all sessions are viewable and accessible. So with practical-
-ly all real world applications you won't notice the difference. But as future
-applications may make use of advanced multisession features, I've started to
-implement the interface for the ISO9660 multisession interface via ioctl
-CDROMMULTISESSION.
-
-5.2 STATUS RECOGNITION
-The drive status recognition does not work correctly in all cases. Changing
-a disk or having the door open, when a drive is already mounted, is detected
-by the Aztech driver itself, but nevertheless causes multiple read attempts
-by the different layers of the ISO9660-filesystem driver, which finally timeout,
-so you have to wait quite a little... But isn't it bad style to change a disk
-in a mounted drive, anyhow ?!
-
-The driver uses busy wait in most cases for the drive handshake (macros
-STEN_LOW and DTEN_LOW). I tested with a 486/DX2 at 66MHz and a Pentium at
-60MHz and 90MHz. Whenever you use a much faster machine you are likely to get
-timeout messages. In that case edit aztcd.h and increase the timeout value
-AZT_TIMEOUT.
-
-For some 'slow' drive commands I implemented waiting with a timer waitqueue
-(macro STEN_LOW_WAIT). If you get this timeout message, you may also edit
-aztcd.h and increase the timeout value AZT_STATUS_DELAY. The waitqueue has
-shown to be a little critical. If you get kernel panic messages, edit aztcd.c
-and substitute STEN_LOW_WAIT by STEN_LOW. Busy waiting with STEN_LOW is more
-stable, but also causes CPU overhead.
-
-5.3 DOSEMU's CD-ROM SUPPORT
-With release 1.20 aztcd was modified to allow access to CD-ROMS when running
-under dosemu-0.60.0 aztcd-versions before 1.20 are most likely to crash
-Linux, when a CD-ROM is accessed under dosemu. This problem has partly been
-fixed, but still when accessing a directory for the first time the system
-might hang for some 30sec. So be patient, when using dosemu's CD-ROM support
-in combination with aztcd :-) !
-This problem has now (July 1995) been fixed by a modification to dosemu's
-CD-ROM driver. The new version came with dosemu-0.60.2, see dosemu's
-README.CDROM.
-
-6. BUG REPORTS
-Please send detailed bug reports and bug fixes via EMail to
-
- Werner.Zimmermann@fht-esslingen.de
-
-Please include a description of your CD-ROM drive type and interface card,
-the exact firmware message during Linux bootup, the version number of the
-AZTECH-CDROM-driver and the Linux kernel version. Also a description of your
-system's other hardware could be of interest, especially microprocessor type,
-clock frequency, other interface cards such as soundcards, ethernet adapter,
-game cards etc..
-
-I will try to collect the reports and make the necessary modifications from
-time to time. I may also come back to you directly with some bug fixes and
-ask you to do further testing and debugging.
-
-Editors of CD-ROMs are invited to send a 'cooperation' copy of their
-CD-ROMs to the volunteers, who provided the CD-ROM support for Linux. My
-snail mail address for such 'stuff' is

-7. OTHER DRIVES
-The following drives ORCHID CDS3110, OKANO CDD110, WEARNES CDD110 and Conrad
-TXC Nr. 993123-series 04 nearly look the same as AZTECH CDA268-01A, especially
-they seem to use the same command codes. So it was quite simple to make the
-AZTECH driver work with these drives.
-
-Unfortunately I do not have any of these drives available, so I couldn't test
-it myself. In some installations, it seems necessary to initialize the drive
-with the DOS driver before (especially if combined with a sound card) and then
-do a warm boot (CTRL-ALT-RESET) or start Linux from DOS, e.g. with 'loadlin'.
-
-If you do not succeed, read chapter DEBUGGING. Thanks in advance!
-
-Sorry for the inconvenience, but it is difficult to develop for hardware,
-which you don't have available for testing. So if you like, please help us.
-
-If you do have a CyCDROM CR520ie thanks to Hilmar Berger's help your chances
-are good, that it will work with aztcd. The CR520ie is sold as an IDE-drive
-and really is connected to the IDE interface (primary at 0x1F0 or secondary
-at 0x170, configured as slave, not as master). Nevertheless it is not ATAPI
-compatible but still uses Aztech's command codes.
-
-
-8. DEBUGGING : IF YOU DON'T SUCCEED, TRY THE FOLLOWING
--reread the complete README file
--make sure, that your drive is hardware configured for
- transfer mode: polled
- IRQ: not used
- DMA: not used
- Base Address: something like 300, 320 ...
- You can check this, when you start the DOS driver, which came with your
- drive. By appropriately configuring the drive and the DOS driver you can
- check, whether your drive does operate in this mode correctly under DOS. If
- it does not operate under DOS, it won't under Linux.
- If your drive's base address is something like 0x170 or 0x1F0 (and it is
- not a CyCDROM CR520ie or CR 940ie) you most likely are having an IDE/ATAPI-
- compatible drive, which is not supported by aztcd.c, use ide-cd.c instead.
- Make sure the Base Address is configured correctly in aztcd.h, also make
- sure, that /dev/aztcd0 exists with the correct major number (compare it with
- the entry in file /usr/include/linux/major.h for the Aztech drive).
--insert a CD-ROM and close the tray
--cold boot your PC (i.e. via the power on switch or the reset button)
--if you start Linux via DOS, e.g. using loadlin, make sure, that the DOS
- driver for the CD-ROM drive is not loaded (comment out the calling lines
- in DOS' config.sys!)
--look for the aztcd: init message during Linux init and note them exactly
--log in as root and do a mount -t iso9660 /dev/aztcd0 /mnt
--if you don't succeed in the first time, try several times. Try also to open
- and close the tray, then mount again. Please note carefully all commands
- you typed in and the aztcd-messages, which you get.
--if you get an 'Aztech CD-ROM init: aborted' message, read the remarks about
- the version string below.
-
-If this does not help, do the same with the following differences
--start DOS before; make now sure, that the DOS driver for the CD-ROM is
- loaded under DOS (i.e. uncomment it again in config.sys)
--warm boot your PC (i.e. via CTRL-ALT-DEL)
- if you have it, you can also start via loadlin (try both).
- ...
- Again note all commands and the aztcd-messages.
-
-If you see STEN_LOW or STEN_LOW_WAIT error messages, increase the timeout
-values.
-
-If this still does not help,
--look in aztcd.c for the lines #if 0
- #define AZT_TEST1
- ...
- #endif
- and substitute '#if 0' by '#if 1'.
--recompile your kernel and repeat the above two procedures. You will now get
- a bundle of debugging messages from the driver. Again note your commands
- and the appropriate messages. If you have syslogd running, these messages
- may also be found in syslogd's kernel log file. Nevertheless in some
- installations syslogd does not yet run, when init() is called, thus look for
- the aztcd-messages during init, before the login-prompt appears.
- Then look in aztcd.c, to find out, what happened. The normal calling sequence
- is: aztcd_init() during Linux bootup procedure init()
- after doing a 'mount -t iso9660 /dev/aztcd0 /mnt' the normal calling sequence is
- aztcd_open() -> Status 2c after cold reboot with CDROM or audio CD inserted
- -> Status 8 after warm reboot with CDROM inserted
- -> Status 2e after cold reboot with no disk, closed tray
- -> Status 6e after cold reboot, mount with door open
- aztUpdateToc()
- aztGetDiskInfo()
- aztGetQChannelInfo() repeated several times
- aztGetToc()
- aztGetQChannelInfo() repeated several times
- a list of track information
- do_aztcd_request() }
- azt_transfer() } repeated several times
- azt_poll }
- Check, if there is a difference in the calling sequence or the status flags!
-
- There are a lot of other messages, eg. the ACMD-command code (defined in
- aztcd.h), status info from the getAztStatus-command and the state sequence of
- the finite state machine in azt_poll(). The most important are the status
- messages, look how they are defined and try to understand, if they make
- sense in the context where they appear. With a CD-ROM inserted the status
- should always be 8, except in aztcd_open(). Try to open the tray, insert an
- audio disk, insert no disk or reinsert the CD-ROM and check, if the status
- bits change accordingly. The status bits are the most likely point, where
- the drive manufacturers may implement changes.
-
-If you still don't succeed, a good point to start is to look in aztcd.c in
-function aztcd_init, where the drive should be detected during init. Do the
-following:
--reboot the system with boot parameter 'aztcd=<your base address>,0x79'. With
- parameter 0x79 most of the drive version detection is bypassed. After that
- you should see the complete version string including leading and trailing
- blanks during init.
- Now adapt the statement
- if ((result[1]=='A')&&(result[2]=='Z' ...)
- in aztcd_init() to exactly match the first 3 or 4 letters you have seen.
--Another point is the 'smart' card detection feature in aztcd_init(). Normally
- the CD-ROM drive is ready, when aztcd_init is trying to read the version
- string and a time consuming ACMD_SOFT_RESET command can be avoided. This is
- detected by looking, if AFL_OP_OK can be read correctly. If the CD-ROM drive
- hangs in some unknown state, e.g. because of an error before a warm start or
- because you first operated under DOS, even the version string may be correct,
- but the following commands will not. Then change the code in such a way,
- that the ACMD_SOFT_RESET is issued in any case, by substituting the
- if-statement 'if ( ...=AFL_OP_OK)' by 'if (1)'.
-
-If you succeed, please mail me the exact version string of your drive and
-the code modifications, you have made together with a short explanation.
-If you don't succeed, you may mail me the output of the debugging messages.
-But remember, they are only useful, if they are exact and complete and you
-describe in detail your hardware setup and what you did (cold/warm reboot,
-with/without DOS, DOS-driver started/not started, which Linux-commands etc.)
-
-
-9. TECHNICAL HISTORY OF THE DRIVER
-The AZTECH-Driver is a rework of the Mitsumi-Driver. Four major items had to
-be reworked:
-
-a) The Mitsumi drive does issue complete status information acknowledging
-each command, the Aztech drive does only signal that the command was
-processed. So whenever the complete status information is needed, an extra
-ACMD_GET_STATUS command is issued. The handshake procedure for the drive
-can be found in the functions aztSendCmd(), sendAztCmd() and getAztStatus().
-
-b) The Aztech Drive does not have a ACMD_GET_DISK_INFO command, so the
-necessary info about the number of tracks (firstTrack, lastTrack), disk
-length etc. has to be read from the TOC in the lead in track (see function
-aztGetDiskInfo()).
-
-c) Whenever data is read from the drive, the Mitsumi drive is started with a
-command to read an indefinite (0xffffff) number of sectors. When the appropriate
-number of sectors is read, the drive is stopped by a ACDM_STOP command. This
-does not work with the Aztech drive. I did not find a way to stop it. The
-stop and pause commands do only work in AUDIO mode but not in DATA mode.
-Therefore I had to modify the 'finite state machine' in function azt_poll to
-only read a certain number of sectors and then start a new read on demand. As I
-have not completely understood, how the buffer/caching scheme of the Mitsumi
-driver was implemented, I am not sure, if I have covered all cases correctly,
-whenever you get timeout messages, the bug is most likely to be in that
-function azt_poll() around switch(cmd) .... case ACD_S_DATA.
-
-d) I did not get information about changing drive mode. So I doubt, that the
-code around function azt_poll() case AZT_S_MODE does work. In my test I have
-not been able to switch to reading in raw mode. For reading raw mode, Aztech
-uses a different command than for cooked mode, which I only have implemen-
-ted in the ioctl-section but not in the section which is used by the ISO9660.
-
-The driver was developed on an AST PC with Intel 486/DX2, 8MB RAM, 340MB IDE
-hard disk and on an AST PC with Intel Pentium 60MHz, 16MB RAM, 520MB IDE
-running Linux kernel version 1.0.9 from the LST 1.8 Distribution. The kernel
-was compiled with gcc.2.5.8. My CD-ROM drive is an Aztech CDA268-01A. My
-drive says, that it has Firmware Version AZT26801A1.3. It came with an ISA-bus
-interface card and works with polled I/O without DMA and without interrupts.
-The code for all other drives was 'remote' tested and debugged by a number of
-volunteers on the Internet.
-
-Points, where I feel that possible problems might be and all points where I
-did not completely understand the drive's behaviour or trust my own code are
-marked with /*???*/ in the source code. There are also some parts in the
-Mitsumi driver, where I did not completely understand their code.

-Without the help of P.Bush, Aztech, who delivered technical information
-about the Aztech Drive and without the help of E.Moenkeberg, GWDG, who did a
-great job in analyzing the command structure of various CD-ROM drives, this
-work would not have been possible. E.Moenkeberg was also a great help in
-making the software 'kernel ready' and in answering many of the CDROM-related
-questions in the newsgroups. He really is *the* Linux CD-ROM guru. Thanks
-also to all the guys on the Internet, who collected valuable technical
-information about CDROMs.
-
-Joe Nardone (joe@access.digex.net) was a patient tester even for my first
-trial, which was more than slow, and made suggestions for code improvement.
-Especially the 'finite state machine' azt_poll() was rewritten by Joe to get
-clean C code and avoid the ugly 'gotos', which I copied from mcd.c.
-
-Robby Schirmer (schirmer@fmi.uni-passau.de) tested the audio stuff (ioctls)
-and suggested a lot of patches for them.
-
-Joseph Piskor and Peter Nugent were the first users with the ORCHID CD3110
-and also were very patient with the problems which occurred.
-
-Reinhard Max delivered the information for the CDROM-interface of the
-SoundWave32 soundcards.
-
-Jochen Kunz and Olaf Kaluza delivered the information for supporting Conrad's
-TXC drive.
-
-Hilmar Berger delivered the patches for supporting CyCDROM CR520ie.
-
-Anybody, who is interested in these items should have a look at 'ftp.gwdg.de',
-directory 'pub/linux/cdrom' and at 'ftp.cdrom.com', directory 'pub/cdrom'.
-
-11. PROGRAMMING ADD ONs: cdplay.c
-You can use the ioctl-functions included in aztcd.c in your own programs. As
-an example on how to do this, you will find a tiny CD Player for audio CDs
-named 'cdplay.c'. It allows you to play audio CDs. You can play a specified
-track, pause and resume or skip tracks forward and backwards. If you quit the
-program without stopping the drive, playing is continued. You can also
-(mis)use cdplay to read and hexdump data disks. You can find the code in the
-APPENDIX of this file, which you should cut out with an editor and store in a
-separate file 'cdplay.c'. To compile it and make it executable, do
- gcc -s -Wall -O2 -L/usr/lib cdplay.c -o /usr/local/bin/cdplay # compiles it
- chmod +755 /usr/local/bin/cdplay # makes it executable
- ln -s /dev/aztcd0 /dev/cdrom # creates a link
- (for /usr/lib substitute the top level directory, where your include files
- reside, and for /usr/local/bin the directory, where you want the executable
- binary to reside )
-
-You have to set the correct permissions for cdplay *and* for /dev/mcd0 or
-/dev/aztcd0 in order to use it. Remember, that you should not have /dev/cdrom
-mounted, when you're playing audio CDs.
-
-This program is just a hack for testing the ioctl-functions in aztcd.c. I will
-not maintain it, so if you run into problems, discard it or have a look into
-the source code 'cdplay.c'. The program does only contain a minimum of user
-protection and input error detection. If you use the commands in the wrong
-order or if you try to read a CD at wrong addresses, you may get error messages
-or even hang your machine. If you get STEN_LOW, STEN_LOW_WAIT or segment violation
-error messages when using cdplay, after that, the system might not be stable
-any more, so you'd better reboot. As the ioctl-functions run in kernel mode,
-most normal Linux-multitasking protection features do not work. By using
-uninitialized 'wild' pointers etc., it is easy to write to other users' data
-and program areas, destroy kernel tables etc.. So if you experiment with ioctls
-as always when you are doing systems programming and kernel hacking, you
-should have a backup copy of your system in a safe place (and you also
-should try restoring from a backup copy first)!
-
-A reworked and improved version called 'cdtester.c', which has yet more
-features for testing CDROM-drives can be found in
-Documentation/cdrom/sbpcd, written by E.Moenkeberg.

- CDU31A/CDU33A Driver Info
- -------------------------
-
-Information on the Sony CDU31A/CDU33A CDROM driver for the Linux
-kernel.
-

-
- 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).
-

- 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!

-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.

-This README belongs to release 4.2 or newer of the SoundBlaster Pro
-(Matsushita, Kotobuki, Panasonic, CreativeLabs, Longshine and Teac)
-CD-ROM driver for Linux.
-
-sbpcd really, really is NOT for ANY IDE/ATAPI drive!
-Not even if you have an "original" SoundBlaster card with an IDE interface!
-So, you'd better have a look into README.ide if your port address is 0x1F0,
-0x170, 0x1E8, 0x168 or similar.
-I get tons of mails from IDE/ATAPI drive users - I really can't continue
-any more to answer them all. So, if your drive/interface information sheets
-mention "IDE" (primary, secondary, tertiary, quaternary) and the DOS driver
-invoking line within your CONFIG.SYS is using an address below 0x230:
-DON'T ROB MY LAST NERVE - jumper your interface to address 0x170 and IRQ 15
-(that is the "secondary IDE" configuration), set your drive to "master" and
-use ide-cd as your driver. If you do not have a second IDE hard disk, use the
-LILO commands
- hdb=noprobe hdc=cdrom
-and get lucky.
-To make it fully clear to you: if you mail me about IDE/ATAPI drive problems,
-my answer is above, and I simply will discard your mail, hoping to stop the
-flood and to find time to lead my 12-year old son towards happy computing.
-
-The driver is able to drive the whole family of "traditional" AT-style (that
-is NOT the new "Enhanced IDE" or "ATAPI" drive standard) Matsushita,
-Kotobuki, Panasonic drives, sometimes labelled as "CreativeLabs". The
-well-known drives are CR-521, CR-522, CR-523, CR-562, CR-563.
-CR-574 is an IDE/ATAPI drive.
-
-The Longshine LCS-7260 is a double-speed drive which uses the "old"
-Matsushita command set. It is supported - with help by Serge Robyns.
-Vertos ("Elitegroup Computer Systems", ECS) has a similar drive - support
-has started; get in contact if you have such a "Vertos 100" or "ECS-AT"
-drive.
-
-There exists an "IBM External ISA CD-ROM Drive" which in fact is a CR-563
-with a special controller board. This drive is supported (the interface is
-of the "LaserMate" type), and it is possibly the best buy today (cheaper than
-an internal drive, and you can use it as an internal, too - e.g. plug it into
-a soundcard).
-
-CreativeLabs has a new drive "CD200" and a similar drive "CD200F". The latter
-is made by Funai and sometimes named "E2550UA", newer models may be named
-"MK4015". The CD200F drives should fully work.
-CD200 drives without "F" are still giving problems: drive detection and
-playing audio should work, data access will result in errors. I need qualified
-feedback about the bugs within the data functions or a drive (I never saw a
-CD200).
-
-The quad-speed Teac CD-55A drive is supported, but still does not reach "full
-speed". The data rate already reaches 500 kB/sec if you set SBP_BUFFER_FRAMES
-to 64 (it is not recommended to do that for normal "file access" usage, but it
-can speed up things a lot if you use something like "dd" to read from the
-drive; I use it for verifying self-written CDs this way).
-The drive itself is able to deliver 600 kB/sec, so this needs
-work; with the normal setup, the performance currently is not even as good as
-double-speed.
-
-This driver is NOT for Mitsumi or Sony or Aztech or Philips or XXX drives,
-and again: this driver is in no way usable for any IDE/ATAPI drive. If you
-think your drive should work and it doesn't: send me the DOS driver for your
-beast (gzipped + uuencoded) and your CONFIG.SYS if you want to ask me for help,
-and include an original log message excerpt, and try to give all information
-a complete idiot needs to understand your hassle already with your first
-mail. And if you want to say "as I have mailed you before", be sure that I
-don't remember your "case" by such remarks; at the moment, I have some
-hundreds of open correspondences about Linux CDROM questions (hope to reduce if
-the IDE/ATAPI user questions disappear).
-
-
-This driver will work with the soundcard interfaces (SB Pro, SB 16, Galaxy,
-SoundFX, Mozart, MAD16 ...) and with the "no-sound" cards (Panasonic CI-101P,
-LaserMate, WDH-7001C, Longshine LCS-6853, Teac ...).
-
-It works with the "configurable" interface "Sequoia S-1000", too, which is
-used on the Spea Media FX and Ensonic Soundscape sound cards. You have to
-specify the type "SBPRO 2" and the true CDROM port address with it, not the
-"configuration port" address.
-
-If you have a sound card which needs a "configuration driver" instead of
-jumpers for interface types and addresses (like Mozart cards) - those
-drivers get invoked before the DOS CDROM driver in your CONFIG.SYS, typical
-names are "cdsetup.sys" and "mztinit.sys" - let the sound driver do the
-CDROM port configuration (the leading comments in linux/drivers/sound/mad16.c
-are just for you!). Hannu Savolainen's mad16.c code is able to set up my
-Mozart card - I simply had to add
- #define MAD16_CONF 0x06
- #define MAD16_CDSEL 0x03
-to configure the CDROM interface for type "Panasonic" (LaserMate) and address
-0x340.
-
-The interface type has to get configured in linux/drivers/cdrom/sbpcd.h,
-because the register layout is different between the "SoundBlaster" and the
-"LaserMate" type.
-
-I got a report that the Teac interface card "I/F E117098" is of type
-"SoundBlaster" (i.e. you have to set SBPRO to 1) even with the addresses
-0x300 and above. This is unusual, and it can't get covered by the auto
-probing scheme.
-The Teac 16-bit interface cards (like P/N E950228-00A, default address 0x2C0)
-need the SBPRO 3 setup.
-
-If auto-probing found the drive, the address is correct. The reported type
-may be wrong. A "mount" will give success only if the interface type is set
-right. Playing audio should work with a wrong set interface type, too.
-
-With some Teac and some CD200 drives I have seen interface cards which seem
-to lack the "drive select" lines; always drive 0 gets addressed. To avoid
-"mirror drives" (four drives detected where you only have one) with such
-interface cards, set MAX_DRIVES to 1 and jumper your drive to ID 0 (if
-possible).
-
-
-Up to 4 drives per interface card, and up to 4 interface cards are supported.
-All supported drive families can be mixed, but the CR-521 drives are
-hard-wired to drive ID 0. The drives have to use different drive IDs, and each
-drive has to get a unique minor number (0...3), corresponding indirectly to
-its drive ID.
-The drive IDs may be selected freely from 0 to 3 - they do not have to be in
-consecutive order.
-
-As Don Carroll, don@ds9.us.dell.com or FIDO 1:382/14, told me, it is possible
-to change old drives to any ID, too. He writes in this sense:
- "In order to be able to use more than one single speed drive
- (they do not have the ID jumpers) you must add a DIP switch
- and two resistors. The pads are already on the board next to
- the power connector. You will see the silkscreen for the
- switch if you remove the top cover.
- 1 2 3 4
- ID 0 = x F F x O = "on"
- ID 1 = x O F x F = "off"
- ID 2 = x F O x x = "don't care"
- ID 3 = x O O x
- Next to the switch are the positions for R76 (7k) and R78
- (12k). I had to play around with the resistor values - ID 3
- did not work with other values. If the values are not good,
- ID 3 behaves like ID 0."
-
-To use more than 4 drives, you simply need a second controller card at a
-different address and a second cable.
-
-The driver supports reading of data from the CD and playing of audio tracks.
-The audio part should run with WorkMan, xcdplayer, with the "non-X11" products
-CDplayer and WorkBone - tell me if it is not compatible with other software.
-The only accepted measure for correctness with the audio functions is the
-"cdtester" utility (appended) - most audio player programmers seem to be
-better musicians than programmers. ;-)
-
-With the CR-56x and the CD200 drives, the reading of audio frames is possible.
-This is implemented by an IOCTL function which reads READ_AUDIO frames of
-2352 bytes at once (configurable with the "READ_AUDIO" define, default is 0).
-Reading the same frame a second time gives different data; the frame data
-start at a different position, but all read bytes are valid, and we always
-read 98 consecutive chunks (of 24 Bytes) as a frame. Reading more than 1 frame
-at once possibly misses some chunks at each frame boundary. This lack has to
-get corrected by external, "higher level" software which reads the same frame
-again and tries to find and eliminate overlapping chunks (24-byte-pieces).
-
-The transfer rate with reading audio (1-frame-pieces) currently is very slow.
-This can be better reading bigger chunks, but the "missing" chunks possibly
-occur at the beginning of each single frame.
-The software interface possibly may change a bit the day the SCSI driver
-supports it too.
-
-With all but the CR-52x drives, MultiSession is supported.
-Photo CDs work (the "old" drives like CR-521 can access only the first
-session of a photoCD).
-At ftp.gwdg.de:/pub/linux/hpcdtoppm/ you will find Hadmut Danisch's package to
-convert photo CD image files and Gerd Knorr's viewing utility.
-
-The transfer rate will reach 150 kB/sec with CR-52x drives, 300 kB/sec with
-CR-56x drives, and currently not more than 500 kB/sec (usually less than
-250 kB/sec) with the Teac quad speed drives.
-XA (PhotoCD) disks with "old" drives give only 50 kB/sec.
-
-This release consists of
-- this README file
-- the driver file linux/drivers/cdrom/sbpcd.c
-- the stub files linux/drivers/cdrom/sbpcd[234].c
-- the header file linux/drivers/cdrom/sbpcd.h.
-
-
-To install:
------------
-
-1. Setup your hardware parameters. Though the driver does "auto-probing" at a
- lot of (not all possible!) addresses, this step is recommended for
- everyday use. You should let sbpcd auto-probe once and use the reported
- address if a drive got found. The reported type may be incorrect; it is
- correct if you can mount a data CD. There is no choice for you with the
- type; only one is right, the others are deadly wrong.
-
- a. Go into /usr/src/linux/drivers/cdrom/sbpcd.h and configure it for your
- hardware (near the beginning):
- a1. Set it up for the appropriate type of interface board.
- "Original" CreativeLabs sound cards need "SBPRO 1".
- Most "compatible" sound cards (almost all "non-CreativeLabs" cards)
- need "SBPRO 0".
- The "no-sound" board from OmniCd needs the "SBPRO 1" setup.
- The Teac 8-bit "no-sound" boards need the "SBPRO 1" setup.
- The Teac 16-bit "no-sound" boards need the "SBPRO 3" setup.
- All other "no-sound" boards need the "SBPRO 0" setup.
- The Spea Media FX and Ensoniq SoundScape cards need "SBPRO 2".
- sbpcd.c holds some examples in its auto-probe list.
- If you configure "SBPRO" wrong, the playing of audio CDs will work,
- but you will not be able to mount a data CD.
- a2. Tell the address of your CDROM_PORT (not of the sound port).
- a3. If 4 drives get found, but you have only one, set MAX_DRIVES to 1.
- a4. Set DISTRIBUTION to 0.
- b. Additionally for 2.a1 and 2.a2, the setup may be done during
- boot time (via the "kernel command line" or "LILO option"):
- sbpcd=0x320,LaserMate
- or
- sbpcd=0x230,SoundBlaster
- or
- sbpcd=0x338,SoundScape
- or
- sbpcd=0x2C0,Teac16bit
- This is especially useful if you install a fresh distribution.
- If the second parameter is a number, it gets taken as the type
- setting; 0 is "LaserMate", 1 is "SoundBlaster", 2 is "SoundScape",
- 3 is "Teac16bit".
- So, for example
- sbpcd=0x230,1
- is equivalent to
- sbpcd=0x230,SoundBlaster
-
-2. "cd /usr/src/linux" and do a "make config" and select "y" for Matsushita
- CD-ROM support and for ISO9660 FileSystem support. If you do not have a
- second, third, or fourth controller installed, do not say "y" to the
- secondary Matsushita CD-ROM questions.
-
-3. Then make the kernel image ("make zlilo" or similar).
-
-4. Make the device file(s). This step usually already has been done by the
- MAKEDEV script.
- The driver uses MAJOR 25, so, if necessary, do
- mknod /dev/sbpcd b 25 0 (if you have only one drive)
- and/or
- mknod /dev/sbpcd0 b 25 0
- mknod /dev/sbpcd1 b 25 1
- mknod /dev/sbpcd2 b 25 2
- mknod /dev/sbpcd3 b 25 3
- to make the node(s).
-
- The "first found" drive gets MINOR 0 (regardless of its jumpered ID), the
- "next found" (at the same cable) gets MINOR 1, ...
-
- For a second interface board, you have to make nodes like
- mknod /dev/sbpcd4 b 26 0
- mknod /dev/sbpcd5 b 26 1
- and so on. Use the MAJORs 26, 27, 28.
-
- If you further make a link like
- ln -s sbpcd /dev/cdrom
- you can use the name /dev/cdrom, too.
-
-5. Reboot with the new kernel.
-
-You should now be able to do
- mkdir /CD
-and
- mount -rt iso9660 /dev/sbpcd /CD
-or
- mount -rt iso9660 -o block=2048 /dev/sbpcd /CD
-and see the contents of your CD in the /CD directory.
-To use audio CDs, a mounting is not recommended (and it would fail if the
-first track is not a data track).
-
-
-Using sbpcd as a "loadable module":
------------------------------------
-
-If you do NOT select "Matsushita/Panasonic CDROM driver support" during the
-"make config" of your kernel, you can build the "loadable module" sbpcd.o.
-
-If sbpcd gets used as a module, the support of more than one interface
-card (i.e. drives 4...15) is disabled.
-
-You can specify interface address and type with the "insmod" command like:
- # insmod /usr/src/linux/modules/sbpcd.o sbpcd=0x340,0
-or
- # insmod /usr/src/linux/modules/sbpcd.o sbpcd=0x230,1
-or
- # insmod /usr/src/linux/modules/sbpcd.o sbpcd=0x338,2
-where the last number represents the SBPRO setting (no strings allowed here).
-
-
-Things of interest:
--------------------
-
-The driver is configured to try the LaserMate type of interface at I/O port
-0x0340 first. If this is not appropriate, sbpcd.h should get changed
-(you will find the right place - just at the beginning).
-
-No DMA and no IRQ is used.
-
-To reduce or increase the amount of kernel messages, edit sbpcd.c and play
-with the "DBG_xxx" switches (initialization of the variable "sbpcd_debug").
-Don't forget to reflect on what you do; enabling all DBG_xxx switches at once
-may crash your system, and each message line is accompanied by a delay.
-
-The driver uses the "variable BLOCK_SIZE" feature. To use it, you have to
-specify "block=2048" as a mount option. Doing this will disable the direct
-execution of a binary from the CD; you have to copy it to a device with the
-standard BLOCK_SIZE (1024) first. So, do not use this if your system is
-directly "running from the CDROM" (like some of Yggdrasil's installation
-variants). There are CDs on the market (like the German "unifix" Linux
-distribution) which MUST get handled with a block_size of 1024. Generally,
-one can say all the CDs which hold files of the name YMTRANS.TBL are defective;
-do not use block=2048 with those.
-
-Within sbpcd.h, you will find some "#define"s (e.g. EJECT and JUKEBOX). With
-these, you can configure the driver for some special things.
-You can use the appended program "cdtester" to set the auto-eject feature
-during runtime. Jeff Tranter's "eject" utility can do this, too (and more)
-for you.
-
-There is an ioctl CDROMMULTISESSION to obtain with a user program if
-the CD is an XA disk and - if it is - where the last session starts. The
-"cdtester" program illustrates how to call it.
-
-
-Auto-probing at boot time:
---------------------------
-
-The driver does auto-probing at many well-known interface card addresses,
-but not all:
-Some probings can cause a hang if an NE2000 ethernet card gets touched, because
-SBPCD's auto-probing happens before the initialization of the net drivers.
-Those "hazardous" addresses are excluded from auto-probing; the "kernel
-command line" feature has to be used during installation if you have your
-drive at those addresses. The "module" version is allowed to probe at those
-addresses, too.
-
-The auto-probing looks first at the configured address resp. the address
-submitted by the kernel command line. With this, it is possible to use this
-driver within installation boot floppies, and for any non-standard address,
-too.
-
-Auto-probing will make an assumption about the interface type ("SBPRO" or not),
-based upon the address. That assumption may be wrong (initialization will be
-o.k., but you will get I/O errors during mount). In that case, use the "kernel
-command line" feature and specify address & type at boot time to find out the
-right setup.
-
-For everyday use, address and type should get configured within sbpcd.h. That
-will stop the auto-probing due to success with the first try.
-
-The kernel command "sbpcd=0" suppresses each auto-probing and causes
-the driver not to find any drive; it is meant for people who love sbpcd
-so much that they do not want to miss it, even if they miss the drives. ;-)
-
-If you configure "#define CDROM_PORT 0" in sbpcd.h, the auto-probing is
-initially disabled and needs an explicit kernel command to get activated.
-Once activated, it does not stop before success or end-of-list. This may be
-useful within "universal" CDROM installation boot floppies (but using the
-loadable module would be better because it allows an "extended" auto-probing
-without fearing NE2000 cards).
-
-To shorten the auto-probing list to a single entry, set DISTRIBUTION 0 within
-sbpcd.h.
-
-
-Setting up address and interface type:
---------------------------------------
-
-If your I/O port address is not 0x340, you have to look for the #defines near
-the beginning of sbpcd.h and configure them: set SBPRO to 0 or 1 or 2, and
-change CDROM_PORT to the address of your CDROM I/O port.
-
-Almost all of the "SoundBlaster compatible" cards behave like the no-sound
-interfaces, i.e. need SBPRO 0!
-
-With "original" SB Pro cards, an initial setting of CD_volume through the
-sound card's MIXER register gets done.
-If you are using a "compatible" sound card of types "LaserMate" or "SPEA",
-you can set SOUND_BASE (in sbpcd.h) to get it done with your card, too...
-
-
-Using audio CDs:
-----------------
-
-Workman, WorkBone, xcdplayer, cdplayer and the nice little tool "cdplay" (see
-README.aztcd from the Aztech driver package) should work.
-
-The program CDplayer likes to talk to "/dev/mcd" only, xcdplayer wants
-"/dev/rsr0", workman loves "/dev/sr0" or "/dev/cdrom" - so, make the
-appropriate links to use them without the need to supply parameters.
-
-
-Copying audio tracks:
----------------------
-
-The following program will copy track 1 (or a piece of it) from an audio CD
-into the file "track01":
-
-/*=================== begin program ========================================*/
-/*
- * read an audio track from a CD
- *
- * (c) 1994 Eberhard Moenkeberg <emoenke@gwdg.de>
- * may be used & enhanced freely
- *
- * Due to non-existent sync bytes at the beginning of each audio frame (or due
- * to a firmware bug within all known drives?), it is currently a kind of
- * fortune if two consecutive frames fit together.
- * Usually, they overlap, or a little piece is missing. This happens in units
- * of 24-byte chunks. It has to get fixed by higher-level software (reading
- * until an overlap occurs, and then eliminate the overlapping chunks).
- * ftp.gwdg.de:/pub/linux/misc/cdda2wav-sbpcd.*.tar.gz holds an example of
- * such an algorithm.
- * This example program further is missing to obtain the SubChannel data
- * which belong to each frame.
- *
- * This is only an example of the low-level access routine. The read data are
- * pure 16-bit CDDA values; they have to get converted to make sound out of
- * them.
- * It is no fun to listen to it without prior overlap/underlap correction!

-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>
-
-
-Have fun!

- 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.
-
-Ken Pizzini
-ken@halcyon.com
-
-------------------------------------------------------------------------------
-(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.

-Notes:
-
-The major number for SLM printers is 28 (like ACSI), but as a character
-device, not block device. The minor number is the number of the printer (if
-you have more than one SLM; currently max. 2 (#define-constant) SLMs are
-supported). The device can be opened for reading and writing. If reading it,
-you get some status infos (MODE SENSE data). Writing mode is used for the data
-to be printed. Some ioctls allow to get the printer status and to tune printer
-modes and some internal variables.
-
-A special problem of the SLM driver is the timing and thus the buffering of
-the print data. The problem is that all the data for one page must be present
-in memory when printing starts, else --when swapping occurs-- the timing could
-not be guaranteed. There are several ways to assure this:
-
- 1) Reserve a buffer of 1196k (maximum page size) statically by
- atari_stram_alloc(). The data are collected there until they're complete,
- and then printing starts. Since the buffer is reserved, no further
- considerations about memory and swapping are needed. So this is the
- simplest method, but it needs a lot of memory for just the SLM.
-
- An striking advantage of this method is (supposed the SLM_CONT_CNT_REPROG
- method works, see there), that there are no timing problems with the DMA
- anymore.
-
- 2) The other method would be to reserve the buffer dynamically each time
- printing is required. I could think of looking at mem_map where the
- largest unallocted ST-RAM area is, taking the area, and then extending it
- by swapping out the neighbored pages, until the needed size is reached.
- This requires some mm hacking, but seems possible. The only obstacle could
- be pages that cannot be swapped out (reserved pages)...
-
- 3) Another possibility would be to leave the real data in user space and to
- work with two dribble buffers of about 32k in the driver: While the one
- buffer is DMAed to the SLM, the other can be filled with new data. But
- to keep the timing, that requires that the user data remain in memory and
- are not swapped out. Requires mm hacking, too, but maybe not so bad as
- method 2).

-/* bionet.c BioNet-100 device driver for linux68k.
- *
- * Version: @(#)bionet.c 1.0 02/06/96
- *
- * Author: Hartmut Laue <laue@ifk-mp.uni-kiel.de>
- * and Torsten Narjes <narjes@ifk-mp.uni-kiel.de>
- *
- * Little adaptions for integration into pl7 by Roman Hodek
- *
- * Some changes in bionet_poll_rx by Karl-Heinz Lohner
- *
- 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.

-/* atari_pamsnet.c PAMsNet device driver for linux68k.
- *
- * Version: @(#)PAMsNet.c 0.2ß 03/31/96
- *
- * Author: Torsten Lang <Torsten.Lang@ap.physik.uni-giessen.de>
- * <Torsten.Lang@jung.de>
- *
- * This driver is based on my driver PAMSDMA.c for MiNT-Net and
- * on the driver bionet.c written by
- * Hartmut Laue <laue@ifk-mp.uni-kiel.de>
- * and Torsten Narjes <narjes@ifk-mp.uni-kiel.de>
- *
- * Little adaptions for integration into pl7 by Roman Hodek
- *
- What is it ?
- ------------
- This driver controls the PAMsNet 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'.
-
- 'pamsnet_debug'
- controls the amount of diagnostic messages:
- 0 : no messages
- >0 : see code for meaning of printed messages
-
- 'pamsnet_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 'eth?' 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'.
-
- 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.

- * Definitions of commands understood by the PAMs DMA adaptor.
- *
- * In general the DMA adaptor uses LUN 0, 5, 6 and 7 on one ID changeable
- * by the PAM's Net software.
- *
- * LUN 0 works as a harddisk. You can boot the PAM's Net driver there.
- * LUN 5 works as a harddisk and lets you access the RAM and some I/O HW
- * area. In sector 0, bytes 0x38-0x3d you find the ethernet HW address
- * of the adaptor.
- * LUN 6 works as a harddisk and lets you access the firmware ROM.
- * LUN 7 lets you send and receive packets.
- *
- * Some commands like the INQUIRY command work identical on all used LUNs.
- *
- * UNKNOWN1 seems to read some data.
- * Command length is 6 bytes.
- * UNKNOWN2 seems to read some data (command byte 1 must be !=0). The
- * following bytes seem to be something like an allocation length.
- * Command length is 6 bytes.
- * READPKT reads a packet received by the DMA adaptor.
- * Command length is 6 bytes.
- * WRITEPKT sends a packet transferred by the following DMA phase. The length
- * of the packet is transferred in command bytes 3 and 4.
- * The adaptor automatically replaces the src hw address in an ethernet
- * packet by its own hw address.
- * Command length is 6 bytes.
- * INQUIRY has the same function as the INQUIRY command supported by harddisks
- * and other SCSI devices. It lets you detect which device you found
- * at a given address.
- * Command length is 6 bytes.
- * START initializes the DMA adaptor. After this command it is able to send
- * and receive packets. There is no status byte returned!
- * Command length is 1 byte.
- * NUMPKTS gives back the number of received packets waiting in the queue in
- * the status byte.
- * Command length is 1 byte.
- * UNKNOWN3
- * UNKNOWN4 Function of these three commands is unknown.
- * UNKNOWN5 The command length of these three commands is 1 byte.
- * DESELECT immediately deselects the DMA adaptor. May important with interrupt
- * driven operation.
- * Command length is 1 byte.
- * STOP resets the DMA adaptor. After this command packets can no longer
- * be received or transferred.
- * Command length is 6 byte.
