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!

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?)
