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.
|
|

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.

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.

|
|

0x320 Short Short

|
|
||||||
0x340 Open Short
|
|
||||||
0x360 Open Open
|
|
||||||
|
|
||||||
JP2 and JP3 configure the DMA channel; they must be set the same.

|
|

|

||||||
3 Off Off On
|

|

JP4 Configures the IRQ:

|
|
||||||
IRQ Pin 1 Pin 2 Pin 3 Pin 4
|
|
||||||
--- ----- ----- ----- -----
|

|
|
||||||
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.

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

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

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

If you are using the driver as a module, you can specify your ports and IRQs

Sony-compatible interface. For the IDE-compatible Optics Storage 8001
|
|

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

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

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