Remove legacy CDROM drivers
They are all broken beyond repair. Given that nobody has complained about them (most haven't worked in 2.6 AT ALL), remove them from the tree. A new mitsumi driver that actually works is in progress, it'll get added when completed. Signed-off-by: Jens Axboe <jens.axboe@oracle.com>

10 ---help---
11 If you have a CD-ROM drive that is neither SCSI nor IDE/ATAPI, say Y
12 here, otherwise N. Read the CD-ROM-HOWTO, available from
13 <http://www.tldp.org/docs.html#howto>.
14
15 Note that the answer to this question doesn't directly affect the
16 kernel: saying N will just cause the configurator to skip all
17 the questions about these CD-ROM drives. If you are unsure what you
18 have, say Y and find out whether you have one of the following
19 drives.
20
21 For each of these drivers, a <file:Documentation/cdrom/{driver_name}>
22 exists. Especially in cases where you do not know exactly which kind
23 of drive you have you should read there. Most of these drivers use a
24 file drivers/cdrom/{driver_name}.h where you can define your
25 interface parameters and switch some internal goodies.
26
27 To compile these CD-ROM drivers as a module, choose M instead of Y.
28
29 If you want to use any of these CD-ROM drivers, you also have to
30 answer Y or M to "ISO 9660 CD-ROM file system support" below (this
31 answer will get "defaulted" for you if you enable any of the Linux
32 CD-ROM drivers).

39 CD-3110, Okano or Wearnes CDD110, Conrad TXC, or CyCD-ROM CR520 or
40 CR540 CD-ROM drive. This driver -- just like all these CD-ROM
41 drivers -- is NOT for CD-ROM drives with IDE/ATAPI interfaces, such
42 as Aztech CDA269-031SE. Please read the file
43 <file:Documentation/cdrom/aztcd>.
44
45 If you say Y here, you should also say Y or M to "ISO 9660 CD-ROM

70 depends on CD_NO_IDESCSI && BROKEN_ON_SMP
71 ---help---
72 This driver supports most of the drives which use the Panasonic or
73 Sound Blaster interface. Please read the file

75
76 The Matsushita CR-521, CR-522, CR-523, CR-562, CR-563 drives
77 (sometimes labeled "Creative"), the Creative Labs CD200, the
78 Longshine LCS-7260, the "IBM External ISA CD-ROM" (in fact a CR-56x
79 model), the TEAC CD-55A fall under this category. Some other
80 "electrically compatible" drives (Vertos, Genoa, some Funai models)
81 are currently not supported; for the Sanyo H94A drive currently a
82 separate driver (asked later) is responsible. Most drives have a
83 uniquely shaped faceplate, with a caddyless motorized drawer, but
84 without external brand markings. The older CR-52x drives have a
85 caddy and manual loading/eject, but still no external markings. The
86 driver is able to do an extended auto-probing for interface
87 addresses and drive types; this can help to find facts in cases you
88 are not sure, but can consume some time during the boot process if
89 none of the supported drives gets found. Once your drive got found,
90 you should enter the reported parameters into
91 <file:drivers/cdrom/sbpcd.h> and set "DISTRIBUTION 0" there.
92
93 This driver can support up to four CD-ROM controller cards, and each
94 card can support up to four CD-ROM drives; if you say Y here, you
95 will be asked how many controller cards you have. If compiled as a
96 module, only one controller card (but with up to four drives) is
97 usable.
98

26 HISTORY
27 V0.0 Adaption to Aztech CD268-01A Version 1.3
28 Version is PRE_ALPHA, unresolved points:
29 1. I use busy wait instead of timer wait in STEN_LOW,DTEN_LOW
30 thus driver causes CPU overhead and is very slow
31 2. could not find a way to stop the drive, when it is
32 in data read mode, therefore I had to set
33 msf.end.min/sec/frame to 0:0:1 (in azt_poll); so only one
34 frame can be read in sequence, this is also the reason for
35 3. getting 'timeout in state 4' messages, but nevertheless
36 it works
37 W.Zimmermann, Oct. 31, 1994
38 V0.1 Version is ALPHA, problems #2 and #3 resolved.
39 W.Zimmermann, Nov. 3, 1994
40 V0.2 Modification to some comments, debugging aids for partial test
41 with Borland C under DOS eliminated. Timer interrupt wait
42 STEN_LOW_WAIT additionally to busy wait for STEN_LOW implemented;
43 use it only for the 'slow' commands (ACMD_GET_Q_CHANNEL, ACMD_
44 SEEK_TO_LEAD_IN), all other commands are so 'fast', that busy
45 waiting seems better to me than interrupt rescheduling.
46 Besides that, when used in the wrong place, STEN_LOW_WAIT causes
47 kernel panic.
48 In function aztPlay command ACMD_PLAY_AUDIO added, should make
49 audio functions work. The Aztech drive needs different commands
50 to read data tracks and play audio tracks.
51 W.Zimmermann, Nov. 8, 1994
52 V0.3 Recognition of missing drive during boot up improved (speeded up).
53 W.Zimmermann, Nov. 13, 1994
54 V0.35 Rewrote the control mechanism in azt_poll (formerly mcd_poll)
55 including removal of all 'goto' commands. :-);
56 J. Nardone, Nov. 14, 1994
57 V0.4 Renamed variables and constants to 'azt' instead of 'mcd'; had
58 to make some "compatibility" defines in azt.h; please note,
59 that the source file was renamed to azt.c, the include file to
60 azt.h
61 Speeded up drive recognition during init (will be a little bit
62 slower than before if no drive is installed!); suggested by
63 Robby Schirmer.
64 read_count declared volatile and set to AZT_BUF_SIZ to make
65 drive faster (now 300kB/sec, was 60kB/sec before, measured
66 by 'time dd if=/dev/cdrom of=/dev/null bs=2048 count=4096';
67 different AZT_BUF_SIZes were test, above 16 no further im-
68 provement seems to be possible; suggested by E.Moenkeberg.
69 W.Zimmermann, Nov. 18, 1994
70 V0.42 Included getAztStatus command in GetQChannelInfo() to allow
71 reading Q-channel info on audio disks, if drive is stopped,
72 and some other bug fixes in the audio stuff, suggested by
73 Robby Schirmer.
74 Added more ioctls (reading data in mode 1 and mode 2).
75 Completely removed the old azt_poll() routine.
76 Detection of ORCHID CDS-3110 in aztcd_init implemented.
77 Additional debugging aids (see the readme file).
78 W.Zimmermann, Dec. 9, 1994
79 V0.50 Autodetection of drives implemented.
80 W.Zimmermann, Dec. 12, 1994
81 V0.52 Prepared for including in the standard kernel, renamed most
82 variables to contain 'azt', included autoconf.h
83 W.Zimmermann, Dec. 16, 1994
84 V0.6 Version for being included in the standard Linux kernel.
85 Renamed source and header file to aztcd.c and aztcd.h
86 W.Zimmermann, Dec. 24, 1994
87 V0.7 Changed VERIFY_READ to VERIFY_WRITE in aztcd_ioctl, case
88 CDROMREADMODE1 and CDROMREADMODE2; bug fix in the ioctl,
89 which causes kernel crashes when playing audio, changed
90 include-files (config.h instead of autoconf.h, removed
91 delay.h)
92 W.Zimmermann, Jan. 8, 1995
93 V0.72 Some more modifications for adaption to the standard kernel.
94 W.Zimmermann, Jan. 16, 1995
95 V0.80 aztcd is now part of the standard kernel since version 1.1.83.
96 Modified the SET_TIMER and CLEAR_TIMER macros to comply with
97 the new timer scheme.
98 W.Zimmermann, Jan. 21, 1995
99 V0.90 Included CDROMVOLCTRL, but with my Aztech drive I can only turn
100 the channels on and off. If it works better with your drive,
101 please mail me. Also implemented ACMD_CLOSE for CDROMSTART.
102 W.Zimmermann, Jan. 24, 1995
103 V1.00 Implemented close and lock tray commands. Patches supplied by
104 Frank Racis
105 Added support for loadable MODULEs, so aztcd can now also be
106 loaded by insmod and removed by rmmod during run time
107 Werner Zimmermann, Mar. 24, 95
108 V1.10 Implemented soundcard configuration for Orchid CDS-3110 drives
109 connected to Soundwave32 cards. Release for LST 2.1.
110 (still experimental)
111 Werner Zimmermann, May 8, 95
112 V1.20 Implemented limited support for DOSEMU0.60's cdrom.c. Now it works, but
113 sometimes DOSEMU may hang for 30 seconds or so. A fully functional ver-
114 sion needs an update of Dosemu0.60's cdrom.c, which will come with the
115 next revision of Dosemu.
116 Also Soundwave32 support now works.
117 Werner Zimmermann, May 22, 95
118 V1.30 Auto-eject feature. Inspired by Franc Racis (racis@psu.edu)
119 Werner Zimmermann, July 4, 95
120 V1.40 Started multisession support. Implementation copied from mcdx.c
121 by Heiko Schlittermann. Not tested yet.
122 Werner Zimmermann, July 15, 95
123 V1.50 Implementation of ioctl CDROMRESET, continued multisession, began
124 XA, but still untested. Heavy modifications to drive status de-
125 tection.
126 Werner Zimmermann, July 25, 95
127 V1.60 XA support now should work. Speeded up drive recognition in cases,
128 where no drive is installed.
129 Werner Zimmermann, August 8, 1995
130 V1.70 Multisession support now is completed, but there is still not
131 enough testing done. If you can test it, please contact me. For
132 details please read Documentation/cdrom/aztcd
133 Werner Zimmermann, August 19, 1995
134 V1.80 Modification to suit the new kernel boot procedure introduced
135 with kernel 1.3.33. Will definitely not work with older kernels.
136 Programming done by Linus himself.
137 Werner Zimmermann, October 11, 1995
138 V1.90 Support for Conrad TXC drives, thank's to Jochen Kunz and Olaf Kaluza.
139 Werner Zimmermann, October 21, 1995
140 V2.00 Changed #include "blk.h" to <linux/blk.h> as the directory
141 structure was changed. README.aztcd is now /usr/src/docu-
142 mentation/cdrom/aztcd
143 Werner Zimmermann, November 10, 95
144 V2.10 Started to modify azt_poll to prevent reading beyond end of
145 tracks.
146 Werner Zimmermann, December 3, 95
147 V2.20 Changed some comments
148 Werner Zimmermann, April 1, 96
149 V2.30 Implemented support for CyCDROM CR520, CR940, Code for CR520
150 delivered by H.Berger with preworks by E.Moenkeberg.
151 Werner Zimmermann, April 29, 96
152 V2.40 Reorganized the placement of functions in the source code file
153 to reflect the layered approach; did not actually change code
154 Werner Zimmermann, May 1, 96
155 V2.50 Heiko Eissfeldt suggested to remove some VERIFY_READs in
156 aztcd_ioctl; check_aztcd_media_change modified
157 Werner Zimmermann, May 16, 96
158 V2.60 Implemented Auto-Probing; made changes for kernel's 2.1.xx blocksize
159 Adaption to linux kernel > 2.1.0

1/*
2* Sony CDU-31A CDROM interface device driver.
3*
4* Corey Minyard (minyard@wf-rch.cirr.com)
5*
6* Colossians 3:17
7*
8* See Documentation/cdrom/cdu31a for additional details about this driver.
9*
10* The Sony interface device driver handles Sony interface CDROM
11* drives and provides a complete block-level interface as well as an
12* ioctl() interface compatible with the Sun (as specified in
13* include/linux/cdrom.h). With this interface, CDROMs can be
14* accessed and standard audio CDs can be played back normally.
15*
16* WARNING - All autoprobes have been removed from the driver.
17* You MUST configure the CDU31A via a LILO config
18* at boot time or in lilo.conf. I have the
19* following in my lilo.conf:
20*
21* append="cdu31a=0x1f88,0,PAS"
22*
23* The first number is the I/O base address of the
24* card. The second is the interrupt (0 means none).
25 * The third should be "PAS" if on a Pro-Audio
26 * spectrum, or nothing if on something else.
27 *
28 * This interface is (unfortunately) a polled interface. This is
29 * because most Sony interfaces are set up with DMA and interrupts
30 * disables. Some (like mine) do not even have the capability to
31 * handle interrupts or DMA. For this reason you will see a lot of
32 * the following:
33 *
34 * retry_count = jiffies+ SONY_JIFFIES_TIMEOUT;
35 * while (time_before(jiffies, retry_count) && (! <some condition to wait for))
36 * {
37 * while (handle_sony_cd_attention())
38 * ;
39 *
40 * sony_sleep();
41 * }
42 * if (the condition not met)
43 * {
44 * return an error;
45 * }
46 *
47 * This ugly hack waits for something to happen, sleeping a little
48 * between every try. it also handles attentions, which are
49 * asynchronous events from the drive informing the driver that a disk
50 * has been inserted, removed, etc.
51 *
52 * NEWS FLASH - The driver now supports interrupts but they are
53 * turned off by default. Use of interrupts is highly encouraged, it
54 * cuts CPU usage down to a reasonable level. I had DMA in for a while
55 * but PC DMA is just too slow. Better to just insb() it.
56 *
57 * One thing about these drives: They talk in MSF (Minute Second Frame) format.
58 * There are 75 frames a second, 60 seconds a minute, and up to 75 minutes on a
59 * disk. The funny thing is that these are sent to the drive in BCD, but the
60 * interface wants to see them in decimal. A lot of conversion goes on.
61 *
62 * DRIVER SPECIAL FEATURES
63 * -----------------------
64 *
65 * This section describes features beyond the normal audio and CD-ROM
66 * functions of the drive.
67 *
68 * XA compatibility
69 *
70 * The driver should support XA disks for both the CDU31A and CDU33A.
71 * It does this transparently, the using program doesn't need to set it.
72 *
73 * Multi-Session
74 *
75 * A multi-session disk looks just like a normal disk to the user.
76 * Just mount one normally, and all the data should be there.
77 * A special thanks to Koen for help with this!
78 *
79 * Raw sector I/O
80 *
81 * Using the CDROMREADAUDIO it is possible to read raw audio and data
82 * tracks. Both operations return 2352 bytes per sector. On the data
83 * tracks, the first 12 bytes is not returned by the drive and the value
84 * of that data is indeterminate.

103 * TODO:
104 * CDs with form1 and form2 sectors cause problems
105 * with current read-ahead strategy.
106 *
107 * Credits:
108 * Heiko Eissfeldt <heiko@colossus.escape.de>
109 * For finding abug in the return of the track numbers.
110 * TOC processing redone for proper multisession support.
111 *
112 *
113 * It probably a little late to be adding a history, but I guess I
114 * will start.
115 *
116 * 10/24/95 - Added support for disabling the eject button when the
117 * drive is open. Note that there is a small problem
118 * still here, if the eject button is pushed while the
119 * drive light is flashing, the drive will return a bad
120 * status and be reset. It recovers, though.
121 *
122 * 03/07/97 - Fixed a problem with timers.
123 *
124 *
125 * 18 Spetember 1997 -- Ported to Uniform CD-ROM driver by
126 * Heiko Eissfeldt <heiko@colossus.escape.de> with additional
127 * changes by Erik Andersen <andersee@debian.org>
128 *
129 * 24 January 1998 -- Removed the scd_disc_status() function, which was now
130 * just dead code left over from the port.
131 * Erik Andersen <andersee@debian.org>
132 *
133 * 16 July 1998 -- Drive donated to Erik Andersen by John Kodis
134 * <kodis@jagunet.com>. Work begun on fixing driver to
135 * work under 2.1.X. Added temporary extra printks
136 * which seem to slow it down enough to work.
137 *
138 * 9 November 1999 -- Make kernel-parameter implementation work with 2.3.x
139 * Removed init_module & cleanup_module in favor of
140 * module_init & module_exit.
141 * Torben Mathiasen <tmm@image.dk>
142 *
143 * 22 October 2004 -- Make the driver work in 2.6.X
144 * Added workaround to fix hard lockups on eject
145 * Fixed door locking problem after mounting empty drive
146 * Set double-speed drives to double speed by default
147 * Removed all readahead things - not needed anymore

19History:
20 Started 25 jan 1994. Waiting for documentation...
21 22 feb 1995: 0.1a first reasonably safe polling driver.
22 Two major bugs, one in read_sector and one in
23 do_cm206_request, happened to cancel!
24 25 feb 1995: 0.2a first reasonable interrupt driven version of above.
25 uart writes are still done in polling mode.
26 25 feb 1995: 0.21a writes also in interrupt mode, still some
27 small bugs to be found... Larger buffer.
28 2 mrt 1995: 0.22 Bug found (cd-> nowhere, interrupt was called in
29 initialization), read_ahead of 16. Timeouts implemented.
30 unclear if they do something...
31 7 mrt 1995: 0.23 Start of background read-ahead.
32 18 mrt 1995: 0.24 Working background read-ahead. (still problems)
33 26 mrt 1995: 0.25 Multi-session ioctl added (kernel v1.2).
34 Statistics implemented, though separate stats206.h.
35 Accessible through ioctl 0x1000 (just a number).
36 Hard to choose between v1.2 development and 1.1.75.
37 Bottom-half doesn't work with 1.2...
38 0.25a: fixed... typo. Still problems...
39 1 apr 1995: 0.26 Module support added. Most bugs found. Use kernel 1.2.n.
40 5 apr 1995: 0.27 Auto-probe for the adapter card base address.
41 Auto-probe for the adaptor card irq line.
42 7 apr 1995: 0.28 Added lilo setup support for base address and irq.
43 Use major number 32 (not in this source), officially
44 assigned to this driver.
45 9 apr 1995: 0.29 Added very limited audio support. Toc_header, stop, pause,
46 resume, eject. Play_track ignores track info, because we can't
47 read a table-of-contents entry. Toc_entry is implemented
48 as a `placebo' function: always returns start of disc.
49 3 may 1995: 0.30 Audio support completed. The get_toc_entry function
50 is implemented as a binary search.
51 15 may 1995: 0.31 More work on audio stuff. Workman is not easy to
52 satisfy; changed binary search into linear search.
53 Auto-probe for base address somewhat relaxed.
54 1 jun 1995: 0.32 Removed probe_irq_on/off for module version.
55 10 jun 1995: 0.33 Workman still behaves funny, but you should be
56 able to eject and substitute another disc.
57
58 An adaptation of 0.33 is included in linux-1.3.7 by Eberhard Moenkeberg
59
60 18 jul 1995: 0.34 Patch by Heiko Eissfeldt included, mainly considering
61 verify_area's in the ioctls. Some bugs introduced by
62 EM considering the base port and irq fixed.
63
64 18 dec 1995: 0.35 Add some code for error checking... no luck...
65
66 We jump to reach our goal: version 1.0 in the next stable linux kernel.
67
68 19 mar 1996: 0.95 Different implementation of CDROM_GET_UPC, on
69 request of Thomas Quinot.
70 25 mar 1996: 0.96 Interpretation of opening with O_WRONLY or O_RDWR:
71 open only for ioctl operation, e.g., for operation of
72 tray etc.
73 4 apr 1996: 0.97 First implementation of layer between VFS and cdrom
74 driver, a generic interface. Much of the functionality
75 of cm206_open() and cm206_ioctl() is transferred to a
76 new file cdrom.c and its header ucdrom.h.
77
78 Upgrade to Linux kernel 1.3.78.
79
80 11 apr 1996 0.98 Upgrade to Linux kernel 1.3.85
81 More code moved to cdrom.c
82
83 0.99 Some more small changes to decrease number
84 of oopses at module load;
85
86 27 jul 1996 0.100 Many hours of debugging, kernel change from 1.2.13
87 to 2.0.7 seems to have introduced some weird behavior
88 in (interruptible_)sleep_on(&cd->data): the process
89 seems to be woken without any explicit wake_up in my own
90 code. Patch to try 100x in case such untriggered wake_up's
91 occur.
92
93 28 jul 1996 0.101 Rewriting of the code that receives the command echo,
94 using a fifo to store echoed bytes.
95
96 Branch from 0.99:
97
98 0.99.1.0 Update to kernel release 2.0.10 dev_t -> kdev_t
99 (emoenke) various typos found by others. extra
100 module-load oops protection.
101
102 0.99.1.1 Initialization constant cdrom_dops.speed
103 changed from float (2.0) to int (2); Cli()-sti() pair
104 around cm260_reset() in module initialization code.
105
106 0.99.1.2 Changes literally as proposed by Scott Snyder
107 <snyder@d0sgif.fnal.gov> for the 2.1 kernel line, which
108 have to do mainly with the poor minor support i had. The
109 major new concept is to change a cdrom driver's
110 operations struct from the capabilities struct. This
111 reflects the fact that there is one major for a driver,
112 whilst there can be many minors whith completely
113 different capabilities.
114
115 0.99.1.3 More changes for operations/info separation.
116
117 0.99.1.4 Added speed selection (someone had to do this
118 first).
119
120 23 jan 1997 0.99.1.5 MODULE_PARMS call added.
121
122 23 jan 1997 0.100.1.2--0.100.1.5 following similar lines as
123 0.99.1.1--0.99.1.5. I get too many complaints about the
124 drive making read errors. What't wrong with the 2.0+
125 kernel line? Why get i (and othe cm206 owners) weird
126 results? Why were things good in the good old 1.1--1.2
127 era? Why don't i throw away the drive?
128
129 2 feb 1997 0.102 Added `volatile' to values in cm206_struct. Seems to
130 reduce many of the problems. Rewrote polling routines
131 to use fixed delays between polls.
132 0.103 Changed printk behavior.
133 0.104 Added a 0.100 -> 0.100.1.1 change
134
13511 feb 1997 0.105 Allow auto_probe during module load, disable
136 with module option "auto_probe=0". Moved some debugging
137 statements to lower priority. Implemented select_speed()
138 function.
139
14013 feb 1997 1.0 Final version for 2.0 kernel line.
141
142 All following changes will be for the 2.1 kernel line.
143
14415 feb 1997 1.1 Keep up with kernel 2.1.26, merge in changes from
145 cdrom.c 0.100.1.1--1.0. Add some more MODULE_PARMS.
146
14714 sep 1997 1.2 Upgrade to Linux 2.1.55. Added blksize_size[], patch
148 sent by James Bottomley <James.Bottomley@columbiasc.ncr.com>.
149
15021 dec 1997 1.4 Upgrade to Linux 2.1.72.
151
15224 jan 1998 Removed the cm206_disc_status() function, as it was now dead
153 code. The Uniform CDROM driver now provides this functionality.
154
1559 Nov. 1999 Make kernel-parameter implementation work with 2.3.x
156 Removed init_module & cleanup_module in favor of
157 module_init & module_exit.
158 Torben Mathiasen <tmm@image.dk>
159 *
160 * Parts of the code are based upon lmscd.c written by Kai Petzke,
161 * sbpcd.c written by Eberhard Moenkeberg, and mcd.c by Martin
162 * Harriss, but any off-the-shelf dynamic programming algorithm won't
163 * be able to find them.
164 *
165 * The cm206 drive interface and the cm260 adapter card seem to be
166 * sufficiently different from their cm205/cm250 counterparts
167 * in order to write a complete new driver.
168 *
169 * I call all routines connected to the Linux kernel something
170 * with `cm206' in it, as this stuff is too series-dependent.
171 *
172 * Currently, my limited knowledge is based on:
173 * - The Linux Kernel Hacker's guide, v. 0.5, by Michael K. Johnson
174 * - Linux Kernel Programmierung, by Michael Beck and others
175 * - Philips/LMS cm206 and cm226 product specification
176 * - Philips/LMS cm260 product specification

25/* Revision history
26
27
28 14-5-95 v0.0 Plays sound tracks. No reading of data CDs yet.
29 Detection of disk change doesn't work.
30 21-5-95 v0.1 First ALPHA version. CD can be mounted. The
31 device major nr is borrowed from the Aztech
32 driver. Speed is around 240 kb/s, as measured
33 with "time dd if=/dev/cdrom of=/dev/null \
34 bs=2048 count=4096".
35 24-6-95 v0.2 Reworked the #defines for the command codes
36 and the like, as well as the structure of
37 the hardware communication protocol, to
38 reflect the "official" documentation, kindly
39 supplied by C.K. Tan, Optics Storage Pte. Ltd.
40 Also tidied up the state machine somewhat.
41 28-6-95 v0.3 Removed the ISP-16 interface code, as this
42 should go into its own driver. The driver now
43 has its own major nr.
44 Disk change detection now seems to work, too.
45 This version became part of the standard
46 kernel as of version 1.3.7
47 24-9-95 v0.4 Re-inserted ISP-16 interface code which I
48 copied from sjcd.c, with a few changes.
49 Updated README.optcd. Submitted for
50 inclusion in 1.3.21
51 29-9-95 v0.4a Fixed bug that prevented compilation as module
52 25-10-95 v0.5 Started multisession code. Implementation
53 copied from Werner Zimmermann, who copied it
54 from Heiko Schlittermann's mcdx.
55 17-1-96 v0.6 Multisession works; some cleanup too.
56 18-4-96 v0.7 Increased some timing constants;
57 thanks to Luke McFarlane. Also tidied up some
58 printk behaviour. ISP16 initialization
59 is now handled by a separate driver.
60
61 09-11-99 Make kernel-parameter implementation work with 2.3.x
62 Removed init_module & cleanup_module in favor of
63 module_init & module_exit.

45 * VERSION HISTORY
46 *
47 * 0.1 initial release, April/May 93, after mcd.c (Martin Harriss)
48 *
49 * 0.2 thek "repeat:"-loop in do_sbpcd_request did not check for
50 * end-of-request_queue (resulting in kernel panic).
51 * Flow control seems stable, but throughput is not better.
52 *
53 * 0.3 interrupt locking totally eliminated (maybe "inb" and "outb"
54 * are still locking) - 0.2 made keyboard-type-ahead losses.
55 * check_sbpcd_media_change added (to use by isofs/inode.c)
56 * - but it detects almost nothing.
57 *
58 * 0.4 use MAJOR 25 definitely.
59 * Almost total re-design to support double-speed drives and
60 * "naked" (no sound) interface cards ("LaserMate" interface type).
61 * Flow control should be exact now.
62 * Don't occupy the SbPro IRQ line (not needed either); will
63 * live together with Hannu Savolainen's sndkit now.
64 * Speeded up data transfer to 150 kB/sec, with help from Kai
65 * Makisara, the "provider" of the "mt" tape utility.
66 * Give "SpinUp" command if necessary.
67 * First steps to support up to 4 drives (but currently only one).
68 * Implemented audio capabilities - workman should work, xcdplayer
69 * gives some problems.
70 * This version is still consuming too much CPU time, and
71 * sleeping still has to be worked on.
72 * During "long" implied seeks, it seems possible that a
73 * ReadStatus command gets ignored. That gives the message
74 * "ResponseStatus timed out" (happens about 6 times here during
75 * a "ls -alR" of the YGGDRASIL LGX-Beta CD). Such a case is
76 * handled without data error, but it should get done better.
77 *
78 * 0.5 Free CPU during waits (again with help from Kai Makisara).
79 * Made it work together with the LILO/kernel setup standard.
80 * Included auto-probing code, as suggested by YGGDRASIL.
81 * Formal redesign to add DDI debugging.
82 * There are still flaws in IOCTL (workman with double speed drive).
83 *
84 * 1.0 Added support for all drive IDs (0...3, no longer only 0)
85 * and up to 4 drives on one controller.
86 * Added "#define MANY_SESSION" for "old" multi session CDs.
87 *
88 * 1.1 Do SpinUp for new drives, too.
89 * Revised for clean compile under "old" kernels (0.99pl9).
90 *
91 * 1.2 Found the "workman with double-speed drive" bug: use the driver's
92 * audio_state, not what the drive is reporting with ReadSubQ.
93 *
94 * 1.3 Minor cleanups.
95 * Refinements regarding Workman.
96 *
97 * 1.4 Read XA disks (PhotoCDs) with "old" drives, too (but only the first
98 * session - no chance to fully access a "multi-session" CD).
99 * This currently still is too slow (50 kB/sec) - but possibly
100 * the old drives won't do it faster.
101 * Implemented "door (un)lock" for new drives (still does not work
102 * as wanted - no lock possible after an unlock).
103 * Added some debugging printout for the UPC/EAN code - but my drives
104 * return only zeroes. Is there no UPC/EAN code written?
105 *
106 * 1.5 Laborate with UPC/EAN code (not better yet).
107 * Adapt to kernel 1.1.8 change (have to explicitly include
108 * <linux/string.h> now).
109 *
110 * 1.6 Trying to read audio frames as data. Impossible with the current
111 * drive firmware levels, as it seems. Awaiting any hint. ;-)
112 * Changed "door unlock": repeat it until success.
113 * Changed CDROMSTOP routine (stop somewhat "softer" so that Workman
114 * won't get confused).
115 * Added a third interface type: Sequoia S-1000, as used with the SPEA
116 * Media FX sound card. This interface (usable for Sony and Mitsumi
117 * drives, too) needs a special configuration setup and behaves like a
118 * LaserMate type after that. Still experimental - I do not have such
119 * an interface.
120 * Use the "variable BLOCK_SIZE" feature (2048). But it does only work
121 * if you give the mount option "block=2048".
122 * The media_check routine is currently disabled; now that it gets
123 * called as it should I fear it must get synchronized for not to
124 * disturb the normal driver's activity.
125 *
126 * 2.0 Version number bumped - two reasons:
127 * - reading audio tracks as data works now with CR-562 and CR-563. We
128 * currently do it by an IOCTL (yet has to get standardized), one frame
129 * at a time; that is pretty slow. But it works.
130 * - we are maintaining now up to 4 interfaces (each up to 4 drives):
131 * did it the easy way - a different MAJOR (25, 26, ...) and a different
132 * copy of the driver (sbpcd.c, sbpcd2.c, sbpcd3.c, sbpcd4.c - only
133 * distinguished by the value of SBPCD_ISSUE and the driver's name),
134 * and a common sbpcd.h file.
135 * Bettered the "ReadCapacity error" problem with old CR-52x drives (the
136 * drives sometimes need a manual "eject/insert" before work): just
137 * reset the drive and do again. Needs lots of resets here and sometimes
138 * that does not cure, so this can't be the solution.
139 *
140 * 2.1 Found bug with multisession CDs (accessing frame 16).
141 * "read audio" works now with address type CDROM_MSF, too.
142 * Bigger audio frame buffer: allows reading max. 4 frames at time; this
143 * gives a significant speedup, but reading more than one frame at once
144 * gives missing chunks at each single frame boundary.
145 *
146 * 2.2 Kernel interface cleanups: timers, init, setup, media check.
147 *
148 * 2.3 Let "door lock" and "eject" live together.
149 * Implemented "close tray" (done automatically during open).
150 *
151 * 2.4 Use different names for device registering.
152 *
153 * 2.5 Added "#if EJECT" code (default: enabled) to automatically eject
154 * the tray during last call to "sbpcd_release".
155 * Added "#if JUKEBOX" code (default: disabled) to automatically eject
156 * the tray during call to "sbpcd_open" if no disk is in.
157 * Turn on the CD volume of "compatible" sound cards, too; just define
158 * SOUND_BASE (in sbpcd.h) accordingly (default: disabled).
159 *
160 * 2.6 Nothing new.
161 *
162 * 2.7 Added CDROMEJECT_SW ioctl to set the "EJECT" behavior on the fly:
163 * 0 disables, 1 enables auto-ejecting. Useful to keep the tray in
164 * during shutdown.
165 *
166 * 2.8 Added first support (still BETA, I need feedback or a drive) for
167 * the Longshine LCS-7260 drives. They appear as double-speed drives
168 * using the "old" command scheme, extended by tray control and door
169 * lock functions.
170 * Found (and fixed preliminary) a flaw with some multisession CDs: we
171 * have to re-direct not only the accesses to frame 16 (the isofs
172 * routines drive it up to max. 100), but also those to the continuation
173 * (repetition) frames (as far as they exist - currently set fix as
174 * 16..20).
175 * Changed default of the "JUKEBOX" define. If you use this default,
176 * your tray will eject if you try to mount without a disk in. Next
177 * mount command will insert the tray - so, just fill in a disk. ;-)
178 *
179 * 2.9 Fulfilled the Longshine LCS-7260 support; with great help and
180 * experiments by Serge Robyns.
181 * First attempts to support the TEAC CD-55A drives; but still not
182 * usable yet.
183 * Implemented the CDROMMULTISESSION ioctl; this is an attempt to handle
184 * multi session CDs more "transparent" (redirection handling has to be
185 * done within the isofs routines, and only for the special purpose of
186 * obtaining the "right" volume descriptor; accesses to the raw device
187 * should not get redirected).
188 *
189 * 3.0 Just a "normal" increment, with some provisions to do it better. ;-)
190 * Introduced "#define READ_AUDIO" to specify the maximum number of
191 * audio frames to grab with one request. This defines a buffer size
192 * within kernel space; a value of 0 will reserve no such space and
193 * disable the CDROMREADAUDIO ioctl. A value of 75 enables the reading
194 * of a whole second with one command, but will use a buffer of more
195 * than 172 kB.
196 * Started CD200 support. Drive detection should work, but nothing
197 * more.
198 *
199 * 3.1 Working to support the CD200 and the Teac CD-55A drives.
200 * AT-BUS style device numbering no longer used: use SCSI style now.
201 * So, the first "found" device has MINOR 0, regardless of the
202 * jumpered drive ID. This implies modifications to the /dev/sbpcd*
203 * entries for some people, but will help the DAU (german TLA, english:
204 * "newbie", maybe ;-) to install his "first" system from a CD.
205 *
206 * 3.2 Still testing with CD200 and CD-55A drives.
207 *
208 * 3.3 Working with CD200 support.
209 *
210 * 3.4 Auto-probing stops if an address of 0 is seen (to be entered with
211 * the kernel command line).
212 * Made the driver "loadable". If used as a module, "audio copy" is
213 * disabled, and the internal read ahead data buffer has a reduced size
214 * of 4 kB; so, throughput may be reduced a little bit with slow CPUs.
215 *
216 * 3.5 Provisions to handle weird photoCDs which have an interrupted
217 * "formatting" immediately after the last frames of some files: simply
218 * never "read ahead" with MultiSession CDs. By this, CPU usage may be
219 * increased with those CDs, and there may be a loss in speed.
220 * Re-structured the messaging system.
221 * The "loadable" version no longer has a limited READ_AUDIO buffer
222 * size.
223 * Removed "MANY_SESSION" handling for "old" multi session CDs.
224 * Added "private" IOCTLs CDROMRESET and CDROMVOLREAD.
225 * Started again to support the TEAC CD-55A drives, now that I found
226 * the money for "my own" drive. ;-)
227 * The TEAC CD-55A support is fairly working now.
228 * I have measured that the drive "delivers" at 600 kB/sec (even with
229 * bigger requests than the drive's 64 kB buffer can satisfy), but
230 * the "real" rate does not exceed 520 kB/sec at the moment.
231 * Caused by the various changes to build in TEAC support, the timed
232 * loops are de-optimized at the moment (less throughput with CR-52x
233 * drives, and the TEAC will give speed only with SBP_BUFFER_FRAMES 64).
234 *
235 * 3.6 Fixed TEAC data read problems with SbPro interfaces.
236 * Initial size of the READ_AUDIO buffer is 0. Can get set to any size
237 * during runtime.
238 *
239 * 3.7 Introduced MAX_DRIVES for some poor interface cards (seen with TEAC
240 * drives) which allow only one drive (ID 0); this avoids repetitive
241 * detection under IDs 1..3.
242 * Elongated cmd_out_T response waiting; necessary for photo CDs with
243 * a lot of sessions.
244 * Bettered the sbpcd_open() behavior with TEAC drives.
245 *
246 * 3.8 Elongated max_latency for CR-56x drives.
247 *
248 * 3.9 Finally fixed the long-known SoundScape/SPEA/Sequoia S-1000 interface
249 * configuration bug.
250 * Now Corey, Heiko, Ken, Leo, Vadim/Eric & Werner are invited to copy
251 * the config_spea() routine into their drivers. ;-)
252 *
253 * 4.0 No "big step" - normal version increment.
254 * Adapted the benefits from 1.3.33.
255 * Fiddled with CDROMREADAUDIO flaws.
256 * Avoid ReadCapacity command with CD200 drives (the MKE 1.01 version
257 * seems not to support it).
258 * Fulfilled "read audio" for CD200 drives, with help of Pete Heist
259 * (heistp@rpi.edu).
260 *
261 * 4.1 Use loglevel KERN_INFO with printk().
262 * Added support for "Vertos 100" drive ("ECS-AT") - it is very similar
263 * to the Longshine LCS-7260. Give feedback if you can - I never saw
264 * such a drive, and I have no specs.
265 *
266 * 4.2 Support for Teac 16-bit interface cards. Can't get auto-detected,
267 * so you have to jumper your card to 0x2C0. Still not 100% - come
268 * in contact if you can give qualified feedback.
269 * Use loglevel KERN_NOTICE with printk(). If you get annoyed by a
270 * flood of unwanted messages and the accompanied delay, try to read
271 * my documentation. Especially the Linux CDROM drivers have to do an
272 * important job for the newcomers, so the "distributed" version has
273 * to fit some special needs. Since generations, the flood of messages
274 * is user-configurable (even at runtime), but to get aware of this, one
275 * needs a special mental quality: the ability to read.
276 *
277 * 4.3 CD200F does not like to receive a command while the drive is
278 * reading the ToC; still trying to solve it.
279 * Removed some redundant verify_area calls (yes, Heiko Eissfeldt
280 * is visiting all the Linux CDROM drivers ;-).
281 *
282 * 4.4 Adapted one idea from tiensivu@pilot.msu.edu's "stripping-down"
283 * experiments: "KLOGD_PAUSE".
284 * Inhibited "play audio" attempts with data CDs. Provisions for a
285 * "data-safe" handling of "mixed" (data plus audio) Cds.
286 *
287 * 4.5 Meanwhile Gonzalo Tornaria <tornaria@cmat.edu.uy> (GTL) built a
288 * special end_request routine: we seem to have to take care for not
289 * to have two processes working at the request list. My understanding
290 * was and is that ll_rw_blk should not call do_sbpcd_request as long
291 * as there is still one call active (the first call will care for all
292 * outstanding I/Os, and if a second call happens, that is a bug in
293 * ll_rw_blk.c).
294 * "Check media change" without touching any drive.
295 *
296 * 4.6 Use a semaphore to synchronize multi-activity; elaborated by Rob
297 * Riggs <rriggs@tesser.com>. At the moment, we simply block "read"
298 * against "ioctl" and vice versa. This could be refined further, but
299 * I guess with almost no performance increase.
300 * Experiments to speed up the CD-55A; again with help of Rob Riggs
301 * (to be true, he gave both, idea & code. ;-)
302 *
303 * 4.61 Ported to Uniform CD-ROM driver by
304 * Heiko Eissfeldt <heiko@colossus.escape.de> with additional
305 * changes by Erik Andersen <andersee@debian.org>
306 *
307 * 4.62 Fix a bug where playing audio left the drive in an unusable state.
308 * Heiko Eissfeldt <heiko@colossus.escape.de>
309 *
310 * November 1999 -- Make kernel-parameter implementation work with 2.3.x
311 * Removed init_module & cleanup_module in favor of
312 * module_init & module_exit.
313 * Torben Mathiasen <tmm@image.dk>
314 *
315 * 4.63 Bug fixes for audio annoyances, new legacy CDROM maintainer.
316 * Annoying things fixed:
317 * TOC reread on automated disk changes
318 * TOC reread on manual cd changes
319 * Play IOCTL tries to play CD before it's actually ready... sometimes.
320 * CD_AUDIO_COMPLETED state so workman (and other playes) can repeat play.
321 * Andrew J. Kroll <ag784@freenet.buffalo.edu> Wed Jul 26 04:24:10 EDT 2000
322 *
323 * 4.64 Fix module parameters - were being completely ignored.
324 * Can also specify max_drives=N as a setup int to get rid of
325 * "ghost" drives on crap hardware (aren't they all?) Paul Gortmaker
326 *
327 * TODO
328 * implement "read all subchannel data" (96 bytes per frame)
329 * remove alot of the virtual status bits and deal with hardware status
330 * move the change of cd for audio to a better place
331 * add debug levels to insmod parameters (trivial)
332 *
333 * special thanks to Kai Makisara (kai.makisara@vtt.fi) for his fine
334 * elaborated speed-up experiments (and the fabulous results!), for
335 * the "push" towards load-free wait loops, and for the extensive mail
336 * thread which brought additional hints and bug fixes.

4487 * so that end_request will discard it.

4492 *
4493 * Could be a race here?? Could e.g. a timer interrupt schedule() us?
4494 * If so, we should copy end_request here, and do it right.. (or
4495 * modify end_request and the block devices).
4496 *
4497 * In any case, the race here would be much small than it was, and
4498 * I couldn't reproduce..
4499 *
4500 * The race could be: suppose CURRENT==NULL. We put our req in the list,
4501 * and we are scheduled. Other process takes over, and gets into
4502 * do_sbpcd_request. It sees CURRENT!=NULL (it is == to our req), so
4503 * proceeds. It ends, so CURRENT is now NULL.. Now we awake somewhere in

6 * Attention! This file contains user-serviceable parts!
7 * I recommend to make use of it...
8 * If you feel helpless, look into Documentation/cdrom/sbpcd
9 * (good idea anyway, at least before mailing me).
10 *
11 * The definitions for the first controller can get overridden by
12 * the kernel command line ("lilo boot option").
13 * Examples:
14 * sbpcd=0x300,LaserMate
15 * or
16 * sbpcd=0x230,SoundBlaster
17 * or
18 * sbpcd=0x338,SoundScape
19 * or
20 * sbpcd=0x2C0,Teac16bit
21 *
22 * If sbpcd gets used as a module, you can load it with
23 * insmod sbpcd.o sbpcd=0x300,0
24 * or
25 * insmod sbpcd.o sbpcd=0x230,1
26 * or
27 * insmod sbpcd.o sbpcd=0x338,2

32
33/*
34 * define your CDROM port base address as CDROM_PORT
35 * and specify the type of your interface card as SBPRO.
36 *
37 * address:
38 * ========
39 * SBPRO type addresses typically are 0x0230 (=0x220+0x10), 0x0250, ...
40 * LASERMATE type (CI-101P, WDH-7001C) addresses typically are 0x0300, ...
41 * SOUNDSCAPE addresses are from the LASERMATE type and range. You have to
42 * specify the REAL address here, not the configuration port address. Look
43 * at the CDROM driver's invoking line within your DOS CONFIG.SYS, or let
44 * sbpcd auto-probe, if you are not firm with the address.
45 * There are some soundcards on the market with 0x0630, 0x0650, ...; their
46 * type is not obvious (both types are possible).
47 *
48 * example: if your SBPRO audio address is 0x220, specify 0x230 and SBPRO 1.
49 * if your soundcard has its CDROM port above 0x300, specify
50 * that address and try SBPRO 0 first.
51 * if your SoundScape configuration port is at 0x330, specify
52 * 0x338 and SBPRO 2.
53 *
54 * interface type:
55 * ===============
56 * set SBPRO to 1 for "true" SoundBlaster card
57 * set SBPRO to 0 for "compatible" soundcards and
58 * for "poor" (no sound) interface cards.
59 * set SBPRO to 2 for Ensonic SoundScape or SPEA Media FX cards
60 * set SBPRO to 3 for Teac 16bit interface cards
61 *
62 * Almost all "compatible" sound boards need to set SBPRO to 0.
63 * If SBPRO is set wrong, the drives will get found - but any
64 * data access will give errors (audio access will work).
65 * The "OmniCD" no-sound interface card from CreativeLabs and most Teac
66 * interface cards need SBPRO 1.
67 *
68 * sound base:
69 * ===========
70 * The SOUND_BASE definition tells if we should try to turn the CD sound
71 * channels on. It will only be of use regarding soundcards with a SbPro
72 * compatible mixer.
73 *
74 * Example: #define SOUND_BASE 0x220 enables the sound card's CD channels
75 * #define SOUND_BASE 0 leaves the soundcard untouched

3 * Sanyo CD-ROM device driver implementation, Version 1.6

10 *
11 * This driver is based on pre-works by Eberhard Moenkeberg (emoenke@gwdg.de);
12 * it was developed under use of mcd.c from Martin Harriss, with help of
13 * Eric van der Maarel (H.T.M.v.d.Maarel@marin.nl).
14 *
15 * It is planned to include these routines into sbpcd.c later - to make
16 * a "mixed use" on one cable possible for all kinds of drives which use
17 * the SoundBlaster/Panasonic style CDROM interface. But today, the
18 * ability to install directly from CDROM is more important than flexibility.

33 *
34 * History:
35 * 1.1 First public release with kernel version 1.3.7.
36 * Written by Vadim Model.
37 * 1.2 Added detection and configuration of cdrom interface
38 * on ISP16 soundcard.
39 * Allow for command line options: sjcd=<io_base>,<irq>,<dma>
40 * 1.3 Some minor changes to README.sjcd.
41 * 1.4 MSS Sound support!! Listen to a CD through the speakers.
42 * 1.5 Module support and bugfixes.
43 * Tray locking.
44 * 1.6 Removed ISP16 code from this driver.
45 * Allow only to set io base address on command line: sjcd=<io_base>
46 * Changes to Documentation/cdrom/sjcd
47 * Added cleanup after any error in the initialisation.
48 * 1.7 Added code to set the sector size tables to prevent the bug present in
49 * the previous version of this driver. Coded added by Anthony Barbachan
50 * from bugfix tip originally suggested by Alan Cox.
51 *
52 * November 1999 -- Make kernel-parameter implementation work with 2.3.x
53 * Removed init_module & cleanup_module in favor of
54 * module_init & module_exit.
55 * Torben Mathiasen <tmm@image.dk>

2 * Sony CDU-535 interface device driver
3 *
4 * This is a modified version of the CDU-31A device driver (see below).
5 * Changes were made using documentation for the CDU-531 (which Sony
6 * assures me is very similar to the 535) and partial disassembly of the
7 * DOS driver. I used Minyard's driver and replaced the CDU-31A
8 * commands with the CDU-531 commands. This was complicated by a different
9 * interface protocol with the drive. The driver is still polled.
10 *
11 * Data transfer rate is about 110 Kb/sec, theoretical maximum is 150 Kb/sec.
12 * I tried polling without the sony_sleep during the data transfers but
13 * it did not speed things up any.
14 *
15 * 1993-05-23 (rgj) changed the major number to 21 to get rid of conflict
16 * with CDU-31A driver. This is the also the number from the Linux
17 * Device Driver Registry for the Sony Drive. Hope nobody else is using it.
18 *
19 * 1993-08-29 (rgj) remove the configuring of the interface board address
20 * from the top level configuration, you have to modify it in this file.
21 *
22 * 1995-01-26 Made module-capable (Joel Katz <Stimpson@Panix.COM>)
23 *
24 * 1995-05-20
25 * Modified to support CDU-510/515 series
26 * (Claudio Porfiri<C.Porfiri@nisms.tei.ericsson.se>)
27 * Fixed to report verify_area() failures
28 * (Heiko Eissfeldt <heiko@colossus.escape.de>)
29 *
30 * 1995-06-01
31 * More changes to support CDU-510/515 series
32 * (Claudio Porfiri<C.Porfiri@nisms.tei.ericsson.se>)
33 *
34 * November 1999 -- Make kernel-parameter implementation work with 2.3.x
35 * Removed init_module & cleanup_module in favor of
36 * module_init & module_exit.
37 * Torben Mathiasen <tmm@image.dk>
38 *
39 * September 2003 - Fix SMP support by removing cli/sti calls.
40 * Using spinlocks with a wait_queue instead.
41 * Felipe Damasio <felipewd@terra.com.br>
42 *
43 * Things to do:
44 * - handle errors and status better, put everything into a single word
45 * - use interrupts (code mostly there, but a big hole still missing)
46 * - handle multi-session CDs?
47 * - use DMA?
48 *
49 * Known Bugs:

59 * Sony CDROM interface device driver.
60 *
61 * Corey Minyard (minyard@wf-rch.cirr.com) (CDU-535 complaints to Ken above)
62 *
63 * Colossians 3:17
64 *
65 * The Sony interface device driver handles Sony interface CDROM
66 * drives and provides a complete block-level interface as well as an
67 * ioctl() interface compatible with the Sun (as specified in
68 * include/linux/cdrom.h). With this interface, CDROMs can be
69 * accessed and standard audio CDs can be played back normally.
70 *
71 * This interface is (unfortunately) a polled interface. This is
72 * because most Sony interfaces are set up with DMA and interrupts
73 * disables. Some (like mine) do not even have the capability to
74 * handle interrupts or DMA. For this reason you will see a bit of
75 * the following:
76 *
77 * snap = jiffies;
78 * while (jiffies-snap < SONY_JIFFIES_TIMEOUT)
79 * {
80 * if (some_condition())
81 * break;
82 * sony_sleep();
83 * }
84 * if (some_condition not met)
85 * {
86 * return an_error;
87 * }
88 *
89 * This ugly hack waits for something to happen, sleeping a little
90 * between every try. (The conditional is written so that jiffies
91 * wrap-around is handled properly.)
92 *
93 * One thing about these drives: They talk in MSF (Minute Second Frame) format.
94 * There are 75 frames a second, 60 seconds a minute, and up to 75 minutes on a
95 * disk. The funny thing is that these are sent to the drive in BCD, but the
96 * interface wants to see them in decimal. A lot of conversion goes on.
