- * VERSION HISTORY
- *
- * 0.1 initial release, April/May 93, after mcd.c (Martin Harriss)
- *
- * 0.2 thek "repeat:"-loop in do_sbpcd_request did not check for
- * end-of-request_queue (resulting in kernel panic).
- * Flow control seems stable, but throughput is not better.
- *
- * 0.3 interrupt locking totally eliminated (maybe "inb" and "outb"
- * are still locking) - 0.2 made keyboard-type-ahead losses.
- * check_sbpcd_media_change added (to use by isofs/inode.c)
- * - but it detects almost nothing.
- *
- * 0.4 use MAJOR 25 definitely.
- * Almost total re-design to support double-speed drives and
- * "naked" (no sound) interface cards ("LaserMate" interface type).
- * Flow control should be exact now.
- * Don't occupy the SbPro IRQ line (not needed either); will
- * live together with Hannu Savolainen's sndkit now.
- * Speeded up data transfer to 150 kB/sec, with help from Kai
- * Makisara, the "provider" of the "mt" tape utility.
- * Give "SpinUp" command if necessary.
- * First steps to support up to 4 drives (but currently only one).
- * Implemented audio capabilities - workman should work, xcdplayer
- * gives some problems.
- * This version is still consuming too much CPU time, and
- * sleeping still has to be worked on.
- * During "long" implied seeks, it seems possible that a
- * ReadStatus command gets ignored. That gives the message
- * "ResponseStatus timed out" (happens about 6 times here during
- * a "ls -alR" of the YGGDRASIL LGX-Beta CD). Such a case is
- * handled without data error, but it should get done better.
- *
- * 0.5 Free CPU during waits (again with help from Kai Makisara).
- * Made it work together with the LILO/kernel setup standard.
- * Included auto-probing code, as suggested by YGGDRASIL.
- * Formal redesign to add DDI debugging.
- * There are still flaws in IOCTL (workman with double speed drive).
- *
- * 1.0 Added support for all drive IDs (0...3, no longer only 0)
- * and up to 4 drives on one controller.
- * Added "#define MANY_SESSION" for "old" multi session CDs.
- *
- * 1.1 Do SpinUp for new drives, too.
- * Revised for clean compile under "old" kernels (0.99pl9).
- *
- * 1.2 Found the "workman with double-speed drive" bug: use the driver's
- * audio_state, not what the drive is reporting with ReadSubQ.
- *
- * 1.3 Minor cleanups.
- * Refinements regarding Workman.
- *
- * 1.4 Read XA disks (PhotoCDs) with "old" drives, too (but only the first
- * session - no chance to fully access a "multi-session" CD).
- * This currently still is too slow (50 kB/sec) - but possibly
- * the old drives won't do it faster.
- * Implemented "door (un)lock" for new drives (still does not work
- * as wanted - no lock possible after an unlock).
- * Added some debugging printout for the UPC/EAN code - but my drives
- * return only zeroes. Is there no UPC/EAN code written?
- *
- * 1.5 Laborate with UPC/EAN code (not better yet).
- * Adapt to kernel 1.1.8 change (have to explicitly include
- * <linux/string.h> now).
- *
- * 1.6 Trying to read audio frames as data. Impossible with the current
- * drive firmware levels, as it seems. Awaiting any hint. ;-)
- * Changed "door unlock": repeat it until success.
- * Changed CDROMSTOP routine (stop somewhat "softer" so that Workman
- * won't get confused).
- * Added a third interface type: Sequoia S-1000, as used with the SPEA
- * Media FX sound card. This interface (usable for Sony and Mitsumi
- * drives, too) needs a special configuration setup and behaves like a
- * LaserMate type after that. Still experimental - I do not have such
- * an interface.
- * Use the "variable BLOCK_SIZE" feature (2048). But it does only work
- * if you give the mount option "block=2048".
- * The media_check routine is currently disabled; now that it gets
- * called as it should I fear it must get synchronized for not to
- * disturb the normal driver's activity.
- *
- * 2.0 Version number bumped - two reasons:
- * - reading audio tracks as data works now with CR-562 and CR-563. We
- * currently do it by an IOCTL (yet has to get standardized), one frame
- * at a time; that is pretty slow. But it works.
- * - we are maintaining now up to 4 interfaces (each up to 4 drives):
- * did it the easy way - a different MAJOR (25, 26, ...) and a different
- * copy of the driver (sbpcd.c, sbpcd2.c, sbpcd3.c, sbpcd4.c - only
- * distinguished by the value of SBPCD_ISSUE and the driver's name),
- * and a common sbpcd.h file.
- * Bettered the "ReadCapacity error" problem with old CR-52x drives (the
- * drives sometimes need a manual "eject/insert" before work): just
- * reset the drive and do again. Needs lots of resets here and sometimes
- * that does not cure, so this can't be the solution.
- *
- * 2.1 Found bug with multisession CDs (accessing frame 16).
- * "read audio" works now with address type CDROM_MSF, too.
- * Bigger audio frame buffer: allows reading max. 4 frames at time; this
- * gives a significant speedup, but reading more than one frame at once
- * gives missing chunks at each single frame boundary.
- *
- * 2.2 Kernel interface cleanups: timers, init, setup, media check.
- *
- * 2.3 Let "door lock" and "eject" live together.
- * Implemented "close tray" (done automatically during open).
- *
- * 2.4 Use different names for device registering.
- *
- * 2.5 Added "#if EJECT" code (default: enabled) to automatically eject
- * the tray during last call to "sbpcd_release".
- * Added "#if JUKEBOX" code (default: disabled) to automatically eject
- * the tray during call to "sbpcd_open" if no disk is in.
- * Turn on the CD volume of "compatible" sound cards, too; just define
- * SOUND_BASE (in sbpcd.h) accordingly (default: disabled).
- *
- * 2.6 Nothing new.
- *
- * 2.7 Added CDROMEJECT_SW ioctl to set the "EJECT" behavior on the fly:
- * 0 disables, 1 enables auto-ejecting. Useful to keep the tray in
- * during shutdown.
- *
- * 2.8 Added first support (still BETA, I need feedback or a drive) for
- * the Longshine LCS-7260 drives. They appear as double-speed drives
- * using the "old" command scheme, extended by tray control and door
- * lock functions.
- * Found (and fixed preliminary) a flaw with some multisession CDs: we
- * have to re-direct not only the accesses to frame 16 (the isofs
- * routines drive it up to max. 100), but also those to the continuation
- * (repetition) frames (as far as they exist - currently set fix as
- * 16..20).
- * Changed default of the "JUKEBOX" define. If you use this default,
- * your tray will eject if you try to mount without a disk in. Next
- * mount command will insert the tray - so, just fill in a disk. ;-)
- *
- * 2.9 Fulfilled the Longshine LCS-7260 support; with great help and
- * experiments by Serge Robyns.
- * First attempts to support the TEAC CD-55A drives; but still not
- * usable yet.
- * Implemented the CDROMMULTISESSION ioctl; this is an attempt to handle
- * multi session CDs more "transparent" (redirection handling has to be
- * done within the isofs routines, and only for the special purpose of
- * obtaining the "right" volume descriptor; accesses to the raw device
- * should not get redirected).
- *
- * 3.0 Just a "normal" increment, with some provisions to do it better. ;-)
- * Introduced "#define READ_AUDIO" to specify the maximum number of
- * audio frames to grab with one request. This defines a buffer size
- * within kernel space; a value of 0 will reserve no such space and
- * disable the CDROMREADAUDIO ioctl. A value of 75 enables the reading
- * of a whole second with one command, but will use a buffer of more
- * than 172 kB.
- * Started CD200 support. Drive detection should work, but nothing
- * more.
- *
- * 3.1 Working to support the CD200 and the Teac CD-55A drives.
- * AT-BUS style device numbering no longer used: use SCSI style now.
- * So, the first "found" device has MINOR 0, regardless of the
- * jumpered drive ID. This implies modifications to the /dev/sbpcd*
- * entries for some people, but will help the DAU (german TLA, english:
- * "newbie", maybe ;-) to install his "first" system from a CD.
- *
- * 3.2 Still testing with CD200 and CD-55A drives.
- *
- * 3.3 Working with CD200 support.
- *
- * 3.4 Auto-probing stops if an address of 0 is seen (to be entered with
- * the kernel command line).
- * Made the driver "loadable". If used as a module, "audio copy" is
- * disabled, and the internal read ahead data buffer has a reduced size
- * of 4 kB; so, throughput may be reduced a little bit with slow CPUs.
- *
- * 3.5 Provisions to handle weird photoCDs which have an interrupted
- * "formatting" immediately after the last frames of some files: simply
- * never "read ahead" with MultiSession CDs. By this, CPU usage may be
- * increased with those CDs, and there may be a loss in speed.
- * Re-structured the messaging system.
- * The "loadable" version no longer has a limited READ_AUDIO buffer
- * size.
- * Removed "MANY_SESSION" handling for "old" multi session CDs.
- * Added "private" IOCTLs CDROMRESET and CDROMVOLREAD.
- * Started again to support the TEAC CD-55A drives, now that I found
- * the money for "my own" drive. ;-)
- * The TEAC CD-55A support is fairly working now.
- * I have measured that the drive "delivers" at 600 kB/sec (even with
- * bigger requests than the drive's 64 kB buffer can satisfy), but
- * the "real" rate does not exceed 520 kB/sec at the moment.
- * Caused by the various changes to build in TEAC support, the timed
- * loops are de-optimized at the moment (less throughput with CR-52x
- * drives, and the TEAC will give speed only with SBP_BUFFER_FRAMES 64).
- *
- * 3.6 Fixed TEAC data read problems with SbPro interfaces.
- * Initial size of the READ_AUDIO buffer is 0. Can get set to any size
- * during runtime.
- *
- * 3.7 Introduced MAX_DRIVES for some poor interface cards (seen with TEAC
- * drives) which allow only one drive (ID 0); this avoids repetitive
- * detection under IDs 1..3.
- * Elongated cmd_out_T response waiting; necessary for photo CDs with
- * a lot of sessions.
- * Bettered the sbpcd_open() behavior with TEAC drives.
- *
- * 3.8 Elongated max_latency for CR-56x drives.
- *
- * 3.9 Finally fixed the long-known SoundScape/SPEA/Sequoia S-1000 interface
- * configuration bug.
- * Now Corey, Heiko, Ken, Leo, Vadim/Eric & Werner are invited to copy
- * the config_spea() routine into their drivers. ;-)
- *
- * 4.0 No "big step" - normal version increment.
- * Adapted the benefits from 1.3.33.
- * Fiddled with CDROMREADAUDIO flaws.
- * Avoid ReadCapacity command with CD200 drives (the MKE 1.01 version
- * seems not to support it).
- * Fulfilled "read audio" for CD200 drives, with help of Pete Heist
- * (heistp@rpi.edu).
- *
- * 4.1 Use loglevel KERN_INFO with printk().
- * Added support for "Vertos 100" drive ("ECS-AT") - it is very similar
- * to the Longshine LCS-7260. Give feedback if you can - I never saw
- * such a drive, and I have no specs.
- *
- * 4.2 Support for Teac 16-bit interface cards. Can't get auto-detected,
- * so you have to jumper your card to 0x2C0. Still not 100% - come
- * in contact if you can give qualified feedback.
- * Use loglevel KERN_NOTICE with printk(). If you get annoyed by a
- * flood of unwanted messages and the accompanied delay, try to read
- * my documentation. Especially the Linux CDROM drivers have to do an
- * important job for the newcomers, so the "distributed" version has
- * to fit some special needs. Since generations, the flood of messages
- * is user-configurable (even at runtime), but to get aware of this, one
- * needs a special mental quality: the ability to read.
- *
- * 4.3 CD200F does not like to receive a command while the drive is
- * reading the ToC; still trying to solve it.
- * Removed some redundant verify_area calls (yes, Heiko Eissfeldt
- * is visiting all the Linux CDROM drivers ;-).
- *
- * 4.4 Adapted one idea from tiensivu@pilot.msu.edu's "stripping-down"
- * experiments: "KLOGD_PAUSE".
- * Inhibited "play audio" attempts with data CDs. Provisions for a
- * "data-safe" handling of "mixed" (data plus audio) Cds.
- *
- * 4.5 Meanwhile Gonzalo Tornaria <tornaria@cmat.edu.uy> (GTL) built a
- * special end_request routine: we seem to have to take care for not
- * to have two processes working at the request list. My understanding
- * was and is that ll_rw_blk should not call do_sbpcd_request as long
- * as there is still one call active (the first call will care for all
- * outstanding I/Os, and if a second call happens, that is a bug in
- * ll_rw_blk.c).
- * "Check media change" without touching any drive.
- *
- * 4.6 Use a semaphore to synchronize multi-activity; elaborated by Rob
- * Riggs <rriggs@tesser.com>. At the moment, we simply block "read"
- * against "ioctl" and vice versa. This could be refined further, but
- * I guess with almost no performance increase.
- * Experiments to speed up the CD-55A; again with help of Rob Riggs
- * (to be true, he gave both, idea & code. ;-)
- *
- * 4.61 Ported to Uniform CD-ROM driver by
- * Heiko Eissfeldt <heiko@colossus.escape.de> with additional
- * changes by Erik Andersen <andersee@debian.org>
- *
- * 4.62 Fix a bug where playing audio left the drive in an unusable state.
- * Heiko Eissfeldt <heiko@colossus.escape.de>
- *
- * November 1999 -- Make kernel-parameter implementation work with 2.3.x
- * Removed init_module & cleanup_module in favor of
- * module_init & module_exit.
- * Torben Mathiasen <tmm@image.dk>
- *
- * 4.63 Bug fixes for audio annoyances, new legacy CDROM maintainer.
- * Annoying things fixed:
- * TOC reread on automated disk changes
- * TOC reread on manual cd changes
- * Play IOCTL tries to play CD before it's actually ready... sometimes.
- * CD_AUDIO_COMPLETED state so workman (and other playes) can repeat play.
- * Andrew J. Kroll <ag784@freenet.buffalo.edu> Wed Jul 26 04:24:10 EDT 2000
- *
- * 4.64 Fix module parameters - were being completely ignored.
- * Can also specify max_drives=N as a setup int to get rid of
- * "ghost" drives on crap hardware (aren't they all?) Paul Gortmaker
- *
- * TODO
- * implement "read all subchannel data" (96 bytes per frame)
- * remove alot of the virtual status bits and deal with hardware status
- * move the change of cd for audio to a better place
- * add debug levels to insmod parameters (trivial)
- *
- * special thanks to Kai Makisara (kai.makisara@vtt.fi) for his fine
- * elaborated speed-up experiments (and the fabulous results!), for
- * the "push" towards load-free wait loops, and for the extensive mail
- * thread which brought additional hints and bug fixes.
