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.
