Linux-2.6.12-rc2

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!

+This README belongs to release 4.2 or newer of the SoundBlaster Pro
+(Matsushita, Kotobuki, Panasonic, CreativeLabs, Longshine and Teac)
+CD-ROM driver for Linux.
+
+sbpcd really, really is NOT for ANY IDE/ATAPI drive!
+Not even if you have an "original" SoundBlaster card with an IDE interface!
+So, you'd better have a look into README.ide if your port address is 0x1F0,
+0x170, 0x1E8, 0x168 or similar.
+I get tons of mails from IDE/ATAPI drive users - I really can't continue
+any more to answer them all. So, if your drive/interface information sheets
+mention "IDE" (primary, secondary, tertiary, quaternary) and the DOS driver
+invoking line within your CONFIG.SYS is using an address below 0x230:
+DON'T ROB MY LAST NERVE - jumper your interface to address 0x170 and IRQ 15
+(that is the "secondary IDE" configuration), set your drive to "master" and
+use ide-cd as your driver. If you do not have a second IDE hard disk, use the
+LILO commands
+   hdb=noprobe hdc=cdrom
+and get lucky.
+To make it fully clear to you: if you mail me about IDE/ATAPI drive problems,
+my answer is above, and I simply will discard your mail, hoping to stop the
+flood and to find time to lead my 12-year old son towards happy computing.
+
+The driver is able to drive the whole family of "traditional" AT-style (that
+is NOT the new "Enhanced IDE" or "ATAPI" drive standard) Matsushita,
+Kotobuki, Panasonic drives, sometimes labelled as "CreativeLabs". The
+well-known drives are CR-521, CR-522, CR-523, CR-562, CR-563.
+CR-574 is an IDE/ATAPI drive.
+
+The Longshine LCS-7260 is a double-speed drive which uses the "old"
+Matsushita command set. It is supported - with help by Serge Robyns.
+Vertos ("Elitegroup Computer Systems", ECS) has a similar drive - support
+has started; get in contact if you have such a "Vertos 100" or "ECS-AT"
+drive.
+
+There exists an "IBM External ISA CD-ROM Drive" which in fact is a CR-563
+with a special controller board. This drive is supported (the interface is
+of the "LaserMate" type), and it is possibly the best buy today (cheaper than
+an internal drive, and you can use it as an internal, too - e.g. plug it into
+a soundcard).
+
+CreativeLabs has a new drive "CD200" and a similar drive "CD200F". The latter
+is made by Funai and sometimes named "E2550UA", newer models may be named
+"MK4015". The CD200F drives should fully work.
+CD200 drives without "F" are still giving problems: drive detection and
+playing audio should work, data access will result in errors. I need qualified
+feedback about the bugs within the data functions or a drive (I never saw a
+CD200).
+
+The quad-speed Teac CD-55A drive is supported, but still does not reach "full
+speed". The data rate already reaches 500 kB/sec if you set SBP_BUFFER_FRAMES
+to 64 (it is not recommended to do that for normal "file access" usage, but it
+can speed up things a lot if you use something like "dd" to read from the
+drive; I use it for verifying self-written CDs this way).
+The drive itself is able to deliver 600 kB/sec, so this needs
+work; with the normal setup, the performance currently is not even as good as
+double-speed.
+
+This driver is NOT for Mitsumi or Sony or Aztech or Philips or XXX drives,
+and again: this driver is in no way usable for any IDE/ATAPI drive. If you 
+think your drive should work and it doesn't: send me the DOS driver for your
+beast (gzipped + uuencoded) and your CONFIG.SYS if you want to ask me for help,
+and include an original log message excerpt, and try to give all information
+a complete idiot needs to understand your hassle already with your first
+mail. And if you want to say "as I have mailed you before", be sure that I
+don't remember your "case" by such remarks; at the moment, I have some 
+hundreds of open correspondences about Linux CDROM questions (hope to reduce if
+the IDE/ATAPI user questions disappear). 
+
+
+This driver will work with the soundcard interfaces (SB Pro, SB 16, Galaxy,
+SoundFX, Mozart, MAD16 ...) and with the "no-sound" cards (Panasonic CI-101P,
+LaserMate, WDH-7001C, Longshine LCS-6853, Teac ...).
+
+It works with the "configurable" interface "Sequoia S-1000", too, which is 
+used on the Spea Media FX and Ensonic Soundscape sound cards. You have to
+specify the type "SBPRO 2" and the true CDROM port address with it, not the
+"configuration port" address.
+
+If you have a sound card which needs a "configuration driver" instead of
+jumpers for interface types and addresses (like Mozart cards) - those
+drivers get invoked before the DOS CDROM driver in your CONFIG.SYS, typical
+names are "cdsetup.sys" and "mztinit.sys" - let the sound driver do the
+CDROM port configuration (the leading comments in linux/drivers/sound/mad16.c
+are just for you!). Hannu Savolainen's mad16.c code is able to set up my
+Mozart card - I simply had to add
+   #define MAD16_CONF 0x06
+   #define MAD16_CDSEL 0x03
+to configure the CDROM interface for type "Panasonic" (LaserMate) and address
+0x340.
+
+The interface type has to get configured in linux/drivers/cdrom/sbpcd.h, 
+because the register layout is different between the "SoundBlaster" and the
+"LaserMate" type.
+
+I got a report that the Teac interface card "I/F E117098" is of type
+"SoundBlaster" (i.e. you have to set SBPRO to 1) even with the addresses
+0x300 and above. This is unusual, and it can't get covered by the auto
+probing scheme.
+The Teac 16-bit interface cards (like P/N E950228-00A, default address 0x2C0)
+need the SBPRO 3 setup.
+
+If auto-probing found the drive, the address is correct. The reported type
+may be wrong. A "mount" will give success only if the interface type is set
+right. Playing audio should work with a wrong set interface type, too.
+
+With some Teac and some CD200 drives I have seen interface cards which seem
+to lack the "drive select" lines; always drive 0 gets addressed. To avoid
+"mirror drives" (four drives detected where you only have one) with such
+interface cards, set MAX_DRIVES to 1 and jumper your drive to ID 0 (if
+possible).
+
+
+Up to 4 drives per interface card, and up to 4 interface cards are supported.
+All supported drive families can be mixed, but the CR-521 drives are 
+hard-wired to drive ID 0. The drives have to use different drive IDs, and each
+drive has to get a unique minor number (0...3), corresponding indirectly to 
+its drive ID.
+The drive IDs may be selected freely from 0 to 3 - they do not have to be in
+consecutive order.
+
+As Don Carroll, don@ds9.us.dell.com or FIDO 1:382/14, told me, it is possible
+to change old drives to any ID, too. He writes in this sense:
+   "In order to be able to use more than one single speed drive
+   (they do not have the ID jumpers) you must add a DIP switch
+   and two resistors. The pads are already on the board next to
+   the power connector. You will see the silkscreen for the
+   switch if you remove the top cover.
+                    1 2 3 4
+             ID 0 = x F F x             O = "on"
+             ID 1 = x O F x             F = "off"
+             ID 2 = x F O x             x = "don't care"
+             ID 3 = x O O x
+   Next to the switch are the positions for R76 (7k) and R78
+   (12k). I had to play around with the resistor values - ID 3
+   did not work with other values. If the values are not good,
+   ID 3 behaves like ID 0."
+
+To use more than 4 drives, you simply need a second controller card at a 
+different address and a second cable.
+
+The driver supports reading of data from the CD and playing of audio tracks.
+The audio part should run with WorkMan, xcdplayer, with the "non-X11" products
+CDplayer and WorkBone - tell me if it is not compatible with other software.
+The only accepted measure for correctness with the audio functions is the
+"cdtester" utility (appended) - most audio player programmers seem to be
+better musicians than programmers. ;-)
+
+With the CR-56x and the CD200 drives, the reading of audio frames is possible.
+This is implemented by an IOCTL function which reads READ_AUDIO frames of
+2352 bytes at once (configurable with the "READ_AUDIO" define, default is 0).
+Reading the same frame a second time gives different data; the frame data 
+start at a different position, but all read bytes are valid, and we always
+read 98 consecutive chunks (of 24 Bytes) as a frame. Reading more than 1 frame
+at once possibly misses some chunks at each frame boundary. This lack has to
+get corrected by external, "higher level" software which reads the same frame 
+again and tries to find and eliminate overlapping chunks (24-byte-pieces).
+
+The transfer rate with reading audio (1-frame-pieces) currently is very slow.
+This can be better reading bigger chunks, but the "missing" chunks possibly
+occur at the beginning of each single frame.
+The software interface possibly may change a bit the day the SCSI driver
+supports it too.
+
+With all but the CR-52x drives, MultiSession is supported.
+Photo CDs work (the "old" drives like CR-521 can access only the first
+session of a photoCD).
+At ftp.gwdg.de:/pub/linux/hpcdtoppm/ you will find Hadmut Danisch's package to
+convert photo CD image files and Gerd Knorr's viewing utility.
+
+The transfer rate will reach 150 kB/sec with CR-52x drives, 300 kB/sec with
+CR-56x drives, and currently not more than 500 kB/sec (usually less than
+250 kB/sec) with the Teac quad speed drives.
+XA (PhotoCD) disks with "old" drives give only 50 kB/sec.

+
+
+To install:
+-----------
+
+1. Setup your hardware parameters. Though the driver does "auto-probing" at a
+   lot of (not all possible!) addresses, this step is recommended for
+   everyday use. You should let sbpcd auto-probe once and use the reported
+   address if a drive got found. The reported type may be incorrect; it is
+   correct if you can mount a data CD. There is no choice for you with the
+   type; only one is right, the others are deadly wrong.
+
+   a. Go into /usr/src/linux/drivers/cdrom/sbpcd.h and configure it for your
+      hardware (near the beginning):
+      a1. Set it up for the appropriate type of interface board.
+          "Original" CreativeLabs sound cards need "SBPRO 1".
+          Most "compatible" sound cards (almost all "non-CreativeLabs" cards)
+          need "SBPRO 0".
+          The "no-sound" board from OmniCd needs the "SBPRO 1" setup.
+          The Teac 8-bit "no-sound" boards need the "SBPRO 1" setup.
+          The Teac 16-bit "no-sound" boards need the "SBPRO 3" setup.
+          All other "no-sound" boards need the "SBPRO 0" setup.
+          The Spea Media FX and Ensoniq SoundScape cards need "SBPRO 2".
+          sbpcd.c holds some examples in its auto-probe list.
+          If you configure "SBPRO" wrong, the playing of audio CDs will work,
+          but you will not be able to mount a data CD.
+      a2. Tell the address of your CDROM_PORT (not of the sound port).
+      a3. If 4 drives get found, but you have only one, set MAX_DRIVES to 1.
+      a4. Set DISTRIBUTION to 0.
+   b. Additionally for 2.a1 and 2.a2, the setup may be done during
+      boot time (via the "kernel command line" or "LILO option"):
+          sbpcd=0x320,LaserMate
+      or
+          sbpcd=0x230,SoundBlaster
+      or
+          sbpcd=0x338,SoundScape
+      or
+          sbpcd=0x2C0,Teac16bit
+      This is especially useful if you install a fresh distribution.
+      If the second parameter is a number, it gets taken as the type
+      setting; 0 is "LaserMate", 1 is "SoundBlaster", 2 is "SoundScape",
+      3 is "Teac16bit".
+      So, for example
+          sbpcd=0x230,1
+      is equivalent to
+          sbpcd=0x230,SoundBlaster
+
+2. "cd /usr/src/linux" and do a "make config" and select "y" for Matsushita
+   CD-ROM support and for ISO9660 FileSystem support. If you do not have a
+   second, third, or fourth controller installed, do not say "y" to the 
+   secondary Matsushita CD-ROM questions.
+
+3. Then make the kernel image ("make zlilo" or similar).
+
+4. Make the device file(s). This step usually already has been done by the
+   MAKEDEV script.
+   The driver uses MAJOR 25, so, if necessary, do
+        mknod /dev/sbpcd  b 25 0       (if you have only one drive)
+   and/or
+        mknod /dev/sbpcd0 b 25 0
+        mknod /dev/sbpcd1 b 25 1
+        mknod /dev/sbpcd2 b 25 2
+        mknod /dev/sbpcd3 b 25 3
+   to make the node(s).
+
+   The "first found" drive gets MINOR 0 (regardless of its jumpered ID), the
+   "next found" (at the same cable) gets MINOR 1, ...
+   
+   For a second interface board, you have to make nodes like
+        mknod /dev/sbpcd4 b 26 0
+        mknod /dev/sbpcd5 b 26 1
+   and so on. Use the MAJORs 26, 27, 28.
+
+   If you further make a link like
+        ln -s sbpcd /dev/cdrom
+   you can use the name /dev/cdrom, too.
+
+5. Reboot with the new kernel.
+
+You should now be able to do
+              mkdir /CD
+and 
+              mount -rt iso9660 /dev/sbpcd /CD
+or
+              mount -rt iso9660 -o block=2048 /dev/sbpcd /CD
+and see the contents of your CD in the /CD directory.
+To use audio CDs, a mounting is not recommended (and it would fail if the
+first track is not a data track).
+
+
+Using sbpcd as a "loadable module":
+-----------------------------------
+
+If you do NOT select "Matsushita/Panasonic CDROM driver support" during the
+"make config" of your kernel, you can build the "loadable module" sbpcd.o.
+
+If sbpcd gets used as a module, the support of more than one interface
+card (i.e. drives 4...15) is disabled.
+
+You can specify interface address and type with the "insmod" command like:
+ # insmod /usr/src/linux/modules/sbpcd.o sbpcd=0x340,0
+or
+ # insmod /usr/src/linux/modules/sbpcd.o sbpcd=0x230,1
+or
+ # insmod /usr/src/linux/modules/sbpcd.o sbpcd=0x338,2
+where the last number represents the SBPRO setting (no strings allowed here).
+
+
+Things of interest:
+-------------------
+
+The driver is configured to try the LaserMate type of interface at I/O port
+0x0340 first. If this is not appropriate, sbpcd.h should get changed
+(you will find the right place - just at the beginning).
+
+No DMA and no IRQ is used.
+
+To reduce or increase the amount of kernel messages, edit sbpcd.c and play
+with the "DBG_xxx" switches (initialization of the variable "sbpcd_debug").
+Don't forget to reflect on what you do; enabling all DBG_xxx switches at once
+may crash your system, and each message line is accompanied by a delay.
+
+The driver uses the "variable BLOCK_SIZE" feature. To use it, you have to
+specify "block=2048" as a mount option. Doing this will disable the direct
+execution of a binary from the CD; you have to copy it to a device with the
+standard BLOCK_SIZE (1024) first. So, do not use this if your system is
+directly "running from the CDROM" (like some of Yggdrasil's installation
+variants). There are CDs on the market (like the German "unifix" Linux
+distribution) which MUST get handled with a block_size of 1024. Generally,
+one can say all the CDs which hold files of the name YMTRANS.TBL are defective;
+do not use block=2048 with those.
+
+Within sbpcd.h, you will find some "#define"s (e.g. EJECT and JUKEBOX). With
+these, you can configure the driver for some special things.
+You can use the appended program "cdtester" to set the auto-eject feature
+during runtime. Jeff Tranter's "eject" utility can do this, too (and more)
+for you.
+
+There is an ioctl CDROMMULTISESSION to obtain with a user program if
+the CD is an XA disk and - if it is - where the last session starts. The
+"cdtester" program illustrates how to call it.
+
+
+Auto-probing at boot time:
+--------------------------
+
+The driver does auto-probing at many well-known interface card addresses,
+but not all:
+Some probings can cause a hang if an NE2000 ethernet card gets touched, because
+SBPCD's auto-probing happens before the initialization of the net drivers.
+Those "hazardous" addresses are excluded from auto-probing; the "kernel 
+command line" feature has to be used during installation if you have your 
+drive at those addresses. The "module" version is allowed to probe at those
+addresses, too.
+
+The auto-probing looks first at the configured address resp. the address
+submitted by the kernel command line. With this, it is possible to use this
+driver within installation boot floppies, and for any non-standard address,
+too.
+
+Auto-probing will make an assumption about the interface type ("SBPRO" or not),
+based upon the address. That assumption may be wrong (initialization will be
+o.k., but you will get I/O errors during mount). In that case, use the "kernel
+command line" feature and specify address & type at boot time to find out the
+right setup.
+
+For everyday use, address and type should get configured within sbpcd.h. That
+will stop the auto-probing due to success with the first try.
+
+The kernel command "sbpcd=0" suppresses each auto-probing and causes
+the driver not to find any drive; it is meant for people who love sbpcd
+so much that they do not want to miss it, even if they miss the drives. ;-)  
+
+If you configure "#define CDROM_PORT 0" in sbpcd.h, the auto-probing is
+initially disabled and needs an explicit kernel command to get activated.
+Once activated, it does not stop before success or end-of-list. This may be
+useful within "universal" CDROM installation boot floppies (but using the 
+loadable module would be better because it allows an "extended" auto-probing
+without fearing NE2000 cards).
+
+To shorten the auto-probing list to a single entry, set DISTRIBUTION 0 within
+sbpcd.h.
+
+
+Setting up address and interface type:
+--------------------------------------
+
+If your I/O port address is not 0x340, you have to look for the #defines near
+the beginning of sbpcd.h and configure them: set SBPRO to 0 or 1 or 2, and
+change CDROM_PORT to the address of your CDROM I/O port.
+
+Almost all of the "SoundBlaster compatible" cards behave like the no-sound
+interfaces, i.e. need SBPRO 0! 
+
+With "original" SB Pro cards, an initial setting of CD_volume through the
+sound card's MIXER register gets done.
+If you are using a "compatible" sound card of types "LaserMate" or "SPEA",
+you can set SOUND_BASE (in sbpcd.h) to get it done with your card, too...
+
+
+Using audio CDs:
+----------------
+
+Workman, WorkBone, xcdplayer, cdplayer and the nice little tool "cdplay" (see
+README.aztcd from the Aztech driver package) should work.
+
+The program CDplayer likes to talk to "/dev/mcd" only, xcdplayer wants
+"/dev/rsr0", workman loves "/dev/sr0" or "/dev/cdrom" - so, make the 
+appropriate links to use them without the need to supply parameters.
+
+
+Copying audio tracks:
+---------------------
+
+The following program will copy track 1 (or a piece of it) from an audio CD
+into the file "track01":
+
+/*=================== begin program ========================================*/
+/*
+ * read an audio track from a CD
+ *
+ * (c) 1994 Eberhard Moenkeberg <emoenke@gwdg.de>
+ *          may be used & enhanced freely
+ *
+ * Due to non-existent sync bytes at the beginning of each audio frame (or due
+ * to a firmware bug within all known drives?), it is currently a kind of
+ * fortune if two consecutive frames fit together.
+ * Usually, they overlap, or a little piece is missing. This happens in units
+ * of 24-byte chunks. It has to get fixed by higher-level software (reading
+ * until an overlap occurs, and then eliminate the overlapping chunks). 
+ * ftp.gwdg.de:/pub/linux/misc/cdda2wav-sbpcd.*.tar.gz holds an example of
+ * such an algorithm.
+ * This example program further is missing to obtain the SubChannel data
+ * which belong to each frame.
+ *
+ * This is only an example of the low-level access routine. The read data are
+ * pure 16-bit CDDA values; they have to get converted to make sound out of
+ * them.
+ * It is no fun to listen to it without prior overlap/underlap correction!

+At ftp.gwdg.de:/pub/linux/misc/cdda2wav-sbpcd.*.tar.gz is an adapted version of
+Heiko Eissfeldt's digital-audio to .WAV converter (the original is there, too).
+This is preliminary, as Heiko himself will care about it.
+
+
+Known problems:
+---------------
+
+Currently, the detection of disk change or removal is actively disabled.
+
+Most attempts to read the UPC/EAN code result in a stream of zeroes. All my
+drives are mostly telling there is no UPC/EAN code on disk or there is, but it
+is an all-zero number. I guess now almost no CD holds such a number.
+
+Bug reports, comments, wishes, donations (technical information is a donation,
+too :-) etc. to emoenke@gwdg.de.
+
+SnailMail address, preferable for CD editors if they want to submit a free
