   2  *  sbpcd.c   CD-ROM device driver for the whole family of IDE-style
   3  *            Kotobuki/Matsushita/Panasonic CR-5xx drives for
   4  *            SoundBlaster ("Pro" or "16 ASP" or compatible) cards
   5  *            and for "no-sound" interfaces like Lasermate and the
   6  *            Panasonic CI-101P.
   7  *            Also for the Longshine LCS-7260 drive.
   8  *            Also for the IBM "External ISA CD-Rom" drive.
   9  *            Also for the CreativeLabs CD200 drive (but I still need some
  10  *            detailed bug reports).
  11  *            Also for the TEAC CD-55A drive.
  12  *            Not for Sanyo drives (but sjcd is there...).
  13  *            Not for any other Funai drives than E2550UA (="CD200" with "F").
  14  *
  15  *  NOTE:     This is release 3.9.
  16  *
  17  *  VERSION HISTORY
  18  *
  19  *  0.1  initial release, April/May 93, after mcd.c (Martin Harriss)
  20  *
  21  *  0.2  the "repeat:"-loop in do_sbpcd_request did not check for
  22  *       end-of-request_queue (resulting in kernel panic).
  23  *       Flow control seems stable, but throughput is not better.  
  24  *
  25  *  0.3  interrupt locking totally eliminated (maybe "inb" and "outb"
  26  *       are still locking) - 0.2 made keyboard-type-ahead losses.
  27  *       check_sbpcd_media_change added (to use by isofs/inode.c)
  28  *       - but it detects almost nothing.
  29  *
  30  *  0.4  use MAJOR 25 definitely.
  31  *       Almost total re-design to support double-speed drives and
  32  *       "naked" (no sound) interface cards ("LaserMate" interface type).
  33  *       Flow control should be exact now.
  34  *       Don't occupy the SbPro IRQ line (not needed either); will
  35  *       live together with Hannu Savolainen's sndkit now.
  36  *       Speeded up data transfer to 150 kB/sec, with help from Kai
  37  *       Makisara, the "provider" of the "mt" tape utility.
  38  *       Give "SpinUp" command if necessary.
  39  *       First steps to support up to 4 drives (but currently only one).
  40  *       Implemented audio capabilities - workman should work, xcdplayer
  41  *       gives some problems.
  42  *       This version is still consuming too much CPU time, and
  43  *       sleeping still has to be worked on.
  44  *       During "long" implied seeks, it seems possible that a 
  45  *       ReadStatus command gets ignored. That gives the message
  46  *       "ResponseStatus timed out" (happens about 6 times here during
  47  *       a "ls -alR" of the YGGDRASIL LGX-Beta CD). Such a case is
  48  *       handled without data error, but it should get done better.
  49  *
  50  *  0.5  Free CPU during waits (again with help from Kai Makisara).
  51  *       Made it work together with the LILO/kernel setup standard.
  52  *       Included auto-probing code, as suggested by YGGDRASIL.
  53  *       Formal redesign to add DDI debugging.
  54  *       There are still flaws in IOCTL (workman with double speed drive).
  55  *
  56  *  1.0  Added support for all drive IDs (0...3, no longer only 0)
  57  *       and up to 4 drives on one controller.
  58  *       Added "#define MANY_SESSION" for "old" multi session CDs.
  59  *
  60  *  1.1  Do SpinUp for new drives, too.
  61  *       Revised for clean compile under "old" kernels (0.99pl9).
  62  *
  63  *  1.2  Found the "workman with double-speed drive" bug: use the driver's
  64  *       audio_state, not what the drive is reporting with ReadSubQ.
  65  *
  66  *  1.3  Minor cleanups.
  67  *       Refinements regarding Workman.
  68  *
  69  *  1.4  Read XA disks (PhotoCDs) with "old" drives, too (but only the first
  70  *       session - no chance to fully access a "multi-session" CD).
  71  *       This currently still is too slow (50 kB/sec) - but possibly
  72  *       the old drives won't do it faster.
  73  *       Implemented "door (un)lock" for new drives (still does not work
  74  *       as wanted - no lock possible after an unlock).
  75  *       Added some debugging printout for the UPC/EAN code - but my drives 
  76  *       return only zeroes. Is there no UPC/EAN code written?
  77  *
  78  *  1.5  Laborate with UPC/EAN code (not better yet).
  79  *       Adapt to kernel 1.1.8 change (have to explicitly include
  80  *       <linux/string.h> now).
  81  *
  82  *  1.6  Trying to read audio frames as data. Impossible with the current
  83  *       drive firmware levels, as it seems. Awaiting any hint. ;-)
  84  *       Changed "door unlock": repeat it until success.
  85  *       Changed CDROMSTOP routine (stop somewhat "softer" so that Workman
  86  *       won't get confused).
  87  *       Added a third interface type: Sequoia S-1000, as used with the SPEA
  88  *       Media FX sound card. This interface (usable for Sony and Mitsumi 
  89  *       drives, too) needs a special configuration setup and behaves like a 
  90  *       LaserMate type after that. Still experimental - I do not have such
  91  *       an interface.
  92  *       Use the "variable BLOCK_SIZE" feature (2048). But it does only work
  93  *       if you give the mount option "block=2048".
  94  *       The media_check routine is currently disabled; now that it gets
  95  *       called as it should I fear it must get synchronized for not to
  96  *       disturb the normal driver's activity.
  97  *
  98  *  2.0  Version number bumped - two reasons:
  99  *       - reading audio tracks as data works now with CR-562 and CR-563. We
 100  *       currently do it by an IOCTL (yet has to get standardized), one frame
 101  *       at a time; that is pretty slow. But it works.
 102  *       - we are maintaining now up to 4 interfaces (each up to 4 drives):
 103  *       did it the easy way - a different MAJOR (25, 26, ...) and a different
 104  *       copy of the driver (sbpcd.c, sbpcd2.c, sbpcd3.c, sbpcd4.c - only
 105  *       distinguished by the value of SBPCD_ISSUE and the driver's name),
 106  *       and a common sbpcd.h file.
 107  *       Bettered the "ReadCapacity error" problem with old CR-52x drives (the
 108  *       drives sometimes need a manual "eject/insert" before work): just
 109  *       reset the drive and do again. Needs lots of resets here and sometimes
 110  *       that does not cure, so this can't be the solution.
 111  *
 112  *  2.1  Found bug with multisession CDs (accessing frame 16).
 113  *       "read audio" works now with address type CDROM_MSF, too.
 114  *       Bigger audio frame buffer: allows reading max. 4 frames at time; this
 115  *       gives a significant speedup, but reading more than one frame at once
 116  *       gives missing chunks at each single frame boundary.
 117  *
 118  *  2.2  Kernel interface cleanups: timers, init, setup, media check.
 119  *
 120  *  2.3  Let "door lock" and "eject" live together.
 121  *       Implemented "close tray" (done automatically during open).
 122  *
 123  *  2.4  Use different names for device registering.
 124  *
 125  *  2.5  Added "#if EJECT" code (default: enabled) to automatically eject
 126  *       the tray during last call to "sbpcd_release".
 127  *       Added "#if JUKEBOX" code (default: disabled) to automatically eject
 128  *       the tray during call to "sbpcd_open" if no disk is in.
 129  *       Turn on the CD volume of "compatible" sound cards, too; just define
 130  *       SOUND_BASE (in sbpcd.h) accordingly (default: disabled).
 131  *
 132  *  2.6  Nothing new.  
 133  *
 134  *  2.7  Added CDROMEJECT_SW ioctl to set the "EJECT" behavior on the fly:
 135  *       0 disables, 1 enables auto-ejecting. Useful to keep the tray in
 136  *       during shutdown.
 137  *
 138  *  2.8  Added first support (still BETA, I need feedback or a drive) for
 139  *       the Longshine LCS-7260 drives. They appear as double-speed drives
 140  *       using the "old" command scheme, extended by tray control and door
 141  *       lock functions.
 142  *       Found (and fixed preliminary) a flaw with some multisession CDs: we
 143  *       have to re-direct not only the accesses to frame 16 (the isofs
 144  *       routines drive it up to max. 100), but also those to the continuation
 145  *       (repetition) frames (as far as they exist - currently set fix as
 146  *       16..20).
 147  *       Changed default of the "JUKEBOX" define. If you use this default,
 148  *       your tray will eject if you try to mount without a disk in. Next
 149  *       mount command will insert the tray - so, just fill in a disk. ;-)
 150  *
 151  *  2.9  Fulfilled the Longshine LCS-7260 support; with great help and
 152  *       experiments by Serge Robyns.
 153  *       First attempts to support the TEAC CD-55A drives; but still not
 154  *       usable yet.
 155  *       Implemented the CDROMMULTISESSION ioctl; this is an attempt to handle
 156  *       multi session CDs more "transparent" (redirection handling has to be
 157  *       done within the isofs routines, and only for the special purpose of
 158  *       obtaining the "right" volume descriptor; accesses to the raw device
 159  *       should not get redirected).
 160  *
 161  *  3.0  Just a "normal" increment, with some provisions to do it better. ;-)
 162  *       Introduced "#define READ_AUDIO" to specify the maximum number of 
 163  *       audio frames to grab with one request. This defines a buffer size
 164  *       within kernel space; a value of 0 will reserve no such space and
 165  *       disable the CDROMREADAUDIO ioctl. A value of 75 enables the reading
 166  *       of a whole second with one command, but will use a buffer of more
 167  *       than 172 kB.
 168  *       Started CD200 support. Drive detection should work, but nothing
 169  *       more.
 170  *
 171  *  3.1  Working to support the CD200 and the Teac CD-55A drives.
 172  *       AT-BUS style device numbering no longer used: use SCSI style now.
 173  *       So, the first "found" device has MINOR 0, regardless of the
 174  *       jumpered drive ID. This implies modifications to the /dev/sbpcd*
 175  *       entries for some people, but will help the DAU (german TLA, english:
 176  *       "newbie", maybe ;-) to install his "first" system from a CD.
 177  *
 178  *  3.2  Still testing with CD200 and CD-55A drives.
 179  *
 180  *  3.3  Working with CD200 support.
 181  *
 182  *  3.4  Auto-probing stops if an address of 0 is seen (to be entered with
 183  *       the kernel command line).
 184  *       Made the driver "loadable". If used as a module, "audio copy" is
 185  *       disabled, and the internal read ahead data buffer has a reduced size
 186  *       of 4 kB; so, throughput may be reduced a little bit with slow CPUs.
 187  *
 188  *  3.5  Provisions to handle weird photoCDs which have an interrupted
 189  *       "formatting" immediately after the last frames of some files: simply
 190  *       never "read ahead" with MultiSession CDs. By this, CPU usage may be
 191  *       increased with those CDs, and there may be a loss in speed.
 192  *       Re-structured the messaging system.
 193  *       The "loadable" version no longer has a limited READ_AUDIO buffer
 194  *       size.
 195  *       Removed "MANY_SESSION" handling for "old" multi session CDs.
 196  *       Added "private" IOCTLs CDROMRESET and CDROMVOLREAD.
 197  *       Started again to support the TEAC CD-55A drives, now that I found
 198  *       the money for "my own" drive. ;-)
 199  *       The TEAC CD-55A support is fairly working now.
 200  *       I have measured that the drive "delivers" at 600 kB/sec (even with
 201  *       bigger requests than the drive's 64 kB buffer can satisfy), but
 202  *       the "real" rate does not exceed 520 kB/sec at the moment. 
 203  *       Caused by the various changes to build in TEAC support, the timed
 204  *       loops are de-optimized at the moment (less throughput with CR-52x
 205  *       drives, and the TEAC will give speed only with SBP_BUFFER_FRAMES 64).
 206  *
 207  *  3.6  Fixed TEAC data read problems with SbPro interfaces.
 208  *       Initial size of the READ_AUDIO buffer is 0. Can get set to any size
 209  *       during runtime.
 210  *
 211  *  3.7  Introduced MAX_DRIVES for some poor interface cards (seen with TEAC
 212  *       drives) which allow only one drive (ID 0); this avoids repetitive
 213  *       detection under IDs 1..3. 
 214  *       Elongated cmd_out_T response waiting; necessary for photo CDs with
 215  *       a lot of sessions.
 216  *       Bettered the sbpcd_open() behavior with TEAC drives.
 217  *
 218  *  3.8  Elongated max_latency for CR-56x drives.
 219  *
 220  *  3.9  Finally fixed the long-known SoundScape/SPEA/Sequoia S-1000 interface
 221  *       configuration bug.
 222  *       Now Corey, Heiko, Ken, Leo, Vadim/Eric & Werner are invited to copy
 223  *       the config_spea() routine into their drivers. ;-)
 224  *
 225  *
 226  *  TODO
 227  *
 228  *     disk change detection
 229  *     synchronize multi-activity
 230  *        (data + audio + ioctl + disk change, multiple drives)
 231  *     implement "read all subchannel data" (96 bytes per frame)
 232  *     check if CDROMPLAYMSF can cause a hang
 233  *
 234  *     special thanks to Kai Makisara (kai.makisara@vtt.fi) for his fine
 235  *     elaborated speed-up experiments (and the fabulous results!), for
 236  *     the "push" towards load-free wait loops, and for the extensive mail
 237  *     thread which brought additional hints and bug fixes.
