Linux-2.6.12-rc2v2.6.12-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!

+ *
+ * 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.
