PROGRAMMING ADD ONS: CDPLAY.C - APPENDIX: Source code of cdplay.c ----------------------------------------------------------------------------- - -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 - Prof. Dr. W. Zimmermann - Fachhochschule fuer Technik Esslingen - Fachbereich IT - Flandernstrasse 101 - D-73732 Esslingen - Germany - - -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. - - -10. ACKNOWLEDGMENTS -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. - -Werner Zimmermann -Fachhochschule fuer Technik Esslingen -(EMail: Werner.Zimmermann@fht-esslingen.de) -October, 1997 - ---------------------------------------------------------------------------- -APPENDIX: Source code of cdplay.c - -/* Tiny Audio CD Player - - Copyright 1994, 1995, 1996 Werner Zimmermann (Werner.Zimmermann@fht-esslingen.de) - -This program originally was written to test the audio functions of the -AZTECH.CDROM-driver, but it should work with every CD-ROM drive.

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! - - Oliver Raupach Hannover, Juni 1995 -(raupach@nwfs1.rz.fh-hannover.de) diff --git a/Documentation/cdrom/isp16 b/Documentation/cdrom/isp16 deleted file mode 100644 index cc86533..0000000 --- a/Documentation/cdrom/isp16 +++ /dev/null @@ -1,100 +0,0 @@ - -- Documentation/cdrom/isp16 - -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.

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.

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.

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.

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. |
