| * 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. |

| * |
| * This is a kludge so we don't need to modify end_request. |
| * We put the req we take out after INIT_REQUEST in the requests list, |
| * so that end_request will discard it. |
| * |
| * The bug could be present in other block devices, perhaps we |
| * should modify INIT_REQUEST and end_request instead, and |
| * change every block device.. |
| * |
| * Could be a race here?? Could e.g. a timer interrupt schedule() us? |
| * If so, we should copy end_request here, and do it right.. (or |
| * modify end_request and the block devices). |
| * |
| * In any case, the race here would be much small than it was, and |
| * I couldn't reproduce.. |
| * |
| * The race could be: suppose CURRENT==NULL. We put our req in the list, |
| * and we are scheduled. Other process takes over, and gets into |
| * do_sbpcd_request. It sees CURRENT!=NULL (it is == to our req), so |
| * proceeds. It ends, so CURRENT is now NULL.. Now we awake somewhere in |
| * end_request, but now CURRENT==NULL... oops! |
