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. * */ /* * Trying to merge requests breaks this driver horribly (as in it goes * boom and apparently has done so since 2.3.41).
