| 45 | * VERSION HISTORY |
| 46 | * |
| 47 | * 0.1 initial release, April/May 93, after mcd.c (Martin Harriss) |
| 48 | * |
| 49 | * 0.2 thek "repeat:"-loop in do_sbpcd_request did not check for |
| 50 | * end-of-request_queue (resulting in kernel panic). |
| 51 | * Flow control seems stable, but throughput is not better. |
| 52 | * |
| 53 | * 0.3 interrupt locking totally eliminated (maybe "inb" and "outb" |
| 54 | * are still locking) - 0.2 made keyboard-type-ahead losses. |
| 55 | * check_sbpcd_media_change added (to use by isofs/inode.c) |
| 56 | * - but it detects almost nothing. |
| 57 | * |
| 58 | * 0.4 use MAJOR 25 definitely. |
| 59 | * Almost total re-design to support double-speed drives and |
| 60 | * "naked" (no sound) interface cards ("LaserMate" interface type). |
| 61 | * Flow control should be exact now. |
| 62 | * Don't occupy the SbPro IRQ line (not needed either); will |
| 63 | * live together with Hannu Savolainen's sndkit now. |
| 64 | * Speeded up data transfer to 150 kB/sec, with help from Kai |
| 65 | * Makisara, the "provider" of the "mt" tape utility. |
| 66 | * Give "SpinUp" command if necessary. |
| 67 | * First steps to support up to 4 drives (but currently only one). |
| 68 | * Implemented audio capabilities - workman should work, xcdplayer |
| 69 | * gives some problems. |
| 70 | * This version is still consuming too much CPU time, and |
| 71 | * sleeping still has to be worked on. |
| 72 | * During "long" implied seeks, it seems possible that a |
| 73 | * ReadStatus command gets ignored. That gives the message |
| 74 | * "ResponseStatus timed out" (happens about 6 times here during |
| 75 | * a "ls -alR" of the YGGDRASIL LGX-Beta CD). Such a case is |
| 76 | * handled without data error, but it should get done better. |
| 77 | * |
| 78 | * 0.5 Free CPU during waits (again with help from Kai Makisara). |
| 79 | * Made it work together with the LILO/kernel setup standard. |
| 80 | * Included auto-probing code, as suggested by YGGDRASIL. |
| 81 | * Formal redesign to add DDI debugging. |
| 82 | * There are still flaws in IOCTL (workman with double speed drive). |
| 83 | * |
| 84 | * 1.0 Added support for all drive IDs (0...3, no longer only 0) |
| 85 | * and up to 4 drives on one controller. |
| 86 | * Added "#define MANY_SESSION" for "old" multi session CDs. |
| 87 | * |
| 88 | * 1.1 Do SpinUp for new drives, too. |
| 89 | * Revised for clean compile under "old" kernels (0.99pl9). |
| 90 | * |
| 91 | * 1.2 Found the "workman with double-speed drive" bug: use the driver's |
| 92 | * audio_state, not what the drive is reporting with ReadSubQ. |
| 93 | * |
| 94 | * 1.3 Minor cleanups. |
| 95 | * Refinements regarding Workman. |
| 96 | * |
| 97 | * 1.4 Read XA disks (PhotoCDs) with "old" drives, too (but only the first |
| 98 | * session - no chance to fully access a "multi-session" CD). |
| 99 | * This currently still is too slow (50 kB/sec) - but possibly |
| 100 | * the old drives won't do it faster. |
| 101 | * Implemented "door (un)lock" for new drives (still does not work |
| 102 | * as wanted - no lock possible after an unlock). |
| 103 | * Added some debugging printout for the UPC/EAN code - but my drives |
| 104 | * return only zeroes. Is there no UPC/EAN code written? |
| 105 | * |
| 106 | * 1.5 Laborate with UPC/EAN code (not better yet). |
| 107 | * Adapt to kernel 1.1.8 change (have to explicitly include |
| 108 | * <linux/string.h> now). |
| 109 | * |
| 110 | * 1.6 Trying to read audio frames as data. Impossible with the current |
| 111 | * drive firmware levels, as it seems. Awaiting any hint. ;-) |
| 112 | * Changed "door unlock": repeat it until success. |
| 113 | * Changed CDROMSTOP routine (stop somewhat "softer" so that Workman |
| 114 | * won't get confused). |
| 115 | * Added a third interface type: Sequoia S-1000, as used with the SPEA |
| 116 | * Media FX sound card. This interface (usable for Sony and Mitsumi |
| 117 | * drives, too) needs a special configuration setup and behaves like a |
| 118 | * LaserMate type after that. Still experimental - I do not have such |
| 119 | * an interface. |
| 120 | * Use the "variable BLOCK_SIZE" feature (2048). But it does only work |
| 121 | * if you give the mount option "block=2048". |
| 122 | * The media_check routine is currently disabled; now that it gets |
| 123 | * called as it should I fear it must get synchronized for not to |
| 124 | * disturb the normal driver's activity. |
| 125 | * |
| 126 | * 2.0 Version number bumped - two reasons: |
| 127 | * - reading audio tracks as data works now with CR-562 and CR-563. We |
| 128 | * currently do it by an IOCTL (yet has to get standardized), one frame |
| 129 | * at a time; that is pretty slow. But it works. |
| 130 | * - we are maintaining now up to 4 interfaces (each up to 4 drives): |
| 131 | * did it the easy way - a different MAJOR (25, 26, ...) and a different |
| 132 | * copy of the driver (sbpcd.c, sbpcd2.c, sbpcd3.c, sbpcd4.c - only |
| 133 | * distinguished by the value of SBPCD_ISSUE and the driver's name), |
| 134 | * and a common sbpcd.h file. |
| 135 | * Bettered the "ReadCapacity error" problem with old CR-52x drives (the |
| 136 | * drives sometimes need a manual "eject/insert" before work): just |
| 137 | * reset the drive and do again. Needs lots of resets here and sometimes |
| 138 | * that does not cure, so this can't be the solution. |
| 139 | * |
| 140 | * 2.1 Found bug with multisession CDs (accessing frame 16). |
| 141 | * "read audio" works now with address type CDROM_MSF, too. |
| 142 | * Bigger audio frame buffer: allows reading max. 4 frames at time; this |
| 143 | * gives a significant speedup, but reading more than one frame at once |
| 144 | * gives missing chunks at each single frame boundary. |
| 145 | * |
| 146 | * 2.2 Kernel interface cleanups: timers, init, setup, media check. |
| 147 | * |
| 148 | * 2.3 Let "door lock" and "eject" live together. |
| 149 | * Implemented "close tray" (done automatically during open). |
| 150 | * |
| 151 | * 2.4 Use different names for device registering. |
| 152 | * |
| 153 | * 2.5 Added "#if EJECT" code (default: enabled) to automatically eject |
| 154 | * the tray during last call to "sbpcd_release". |
| 155 | * Added "#if JUKEBOX" code (default: disabled) to automatically eject |
| 156 | * the tray during call to "sbpcd_open" if no disk is in. |
| 157 | * Turn on the CD volume of "compatible" sound cards, too; just define |
| 158 | * SOUND_BASE (in sbpcd.h) accordingly (default: disabled). |
| 159 | * |
| 160 | * 2.6 Nothing new. |
| 161 | * |
| 162 | * 2.7 Added CDROMEJECT_SW ioctl to set the "EJECT" behavior on the fly: |
| 163 | * 0 disables, 1 enables auto-ejecting. Useful to keep the tray in |
| 164 | * during shutdown. |
| 165 | * |
| 166 | * 2.8 Added first support (still BETA, I need feedback or a drive) for |
| 167 | * the Longshine LCS-7260 drives. They appear as double-speed drives |
| 168 | * using the "old" command scheme, extended by tray control and door |
| 169 | * lock functions. |
| 170 | * Found (and fixed preliminary) a flaw with some multisession CDs: we |
| 171 | * have to re-direct not only the accesses to frame 16 (the isofs |
| 172 | * routines drive it up to max. 100), but also those to the continuation |
| 173 | * (repetition) frames (as far as they exist - currently set fix as |
| 174 | * 16..20). |
| 175 | * Changed default of the "JUKEBOX" define. If you use this default, |
| 176 | * your tray will eject if you try to mount without a disk in. Next |
| 177 | * mount command will insert the tray - so, just fill in a disk. ;-) |
| 178 | * |
| 179 | * 2.9 Fulfilled the Longshine LCS-7260 support; with great help and |
| 180 | * experiments by Serge Robyns. |
| 181 | * First attempts to support the TEAC CD-55A drives; but still not |
| 182 | * usable yet. |
| 183 | * Implemented the CDROMMULTISESSION ioctl; this is an attempt to handle |
| 184 | * multi session CDs more "transparent" (redirection handling has to be |
| 185 | * done within the isofs routines, and only for the special purpose of |
| 186 | * obtaining the "right" volume descriptor; accesses to the raw device |
| 187 | * should not get redirected). |
| 188 | * |
| 189 | * 3.0 Just a "normal" increment, with some provisions to do it better. ;-) |
| 190 | * Introduced "#define READ_AUDIO" to specify the maximum number of |
| 191 | * audio frames to grab with one request. This defines a buffer size |
| 192 | * within kernel space; a value of 0 will reserve no such space and |
| 193 | * disable the CDROMREADAUDIO ioctl. A value of 75 enables the reading |
| 194 | * of a whole second with one command, but will use a buffer of more |
| 195 | * than 172 kB. |
| 196 | * Started CD200 support. Drive detection should work, but nothing |
| 197 | * more. |
| 198 | * |
| 199 | * 3.1 Working to support the CD200 and the Teac CD-55A drives. |
| 200 | * AT-BUS style device numbering no longer used: use SCSI style now. |
| 201 | * So, the first "found" device has MINOR 0, regardless of the |
| 202 | * jumpered drive ID. This implies modifications to the /dev/sbpcd* |
| 203 | * entries for some people, but will help the DAU (german TLA, english: |
| 204 | * "newbie", maybe ;-) to install his "first" system from a CD. |
| 205 | * |
| 206 | * 3.2 Still testing with CD200 and CD-55A drives. |
| 207 | * |
| 208 | * 3.3 Working with CD200 support. |
| 209 | * |
| 210 | * 3.4 Auto-probing stops if an address of 0 is seen (to be entered with |
| 211 | * the kernel command line). |
| 212 | * Made the driver "loadable". If used as a module, "audio copy" is |
| 213 | * disabled, and the internal read ahead data buffer has a reduced size |
| 214 | * of 4 kB; so, throughput may be reduced a little bit with slow CPUs. |
| 215 | * |
| 216 | * 3.5 Provisions to handle weird photoCDs which have an interrupted |
| 217 | * "formatting" immediately after the last frames of some files: simply |
| 218 | * never "read ahead" with MultiSession CDs. By this, CPU usage may be |
| 219 | * increased with those CDs, and there may be a loss in speed. |
| 220 | * Re-structured the messaging system. |
| 221 | * The "loadable" version no longer has a limited READ_AUDIO buffer |
| 222 | * size. |
| 223 | * Removed "MANY_SESSION" handling for "old" multi session CDs. |
| 224 | * Added "private" IOCTLs CDROMRESET and CDROMVOLREAD. |
| 225 | * Started again to support the TEAC CD-55A drives, now that I found |
| 226 | * the money for "my own" drive. ;-) |
| 227 | * The TEAC CD-55A support is fairly working now. |
| 228 | * I have measured that the drive "delivers" at 600 kB/sec (even with |
| 229 | * bigger requests than the drive's 64 kB buffer can satisfy), but |
| 230 | * the "real" rate does not exceed 520 kB/sec at the moment. |
| 231 | * Caused by the various changes to build in TEAC support, the timed |
| 232 | * loops are de-optimized at the moment (less throughput with CR-52x |
| 233 | * drives, and the TEAC will give speed only with SBP_BUFFER_FRAMES 64). |
| 234 | * |
| 235 | * 3.6 Fixed TEAC data read problems with SbPro interfaces. |
| 236 | * Initial size of the READ_AUDIO buffer is 0. Can get set to any size |
| 237 | * during runtime. |
| 238 | * |
| 239 | * 3.7 Introduced MAX_DRIVES for some poor interface cards (seen with TEAC |
| 240 | * drives) which allow only one drive (ID 0); this avoids repetitive |
| 241 | * detection under IDs 1..3. |
| 242 | * Elongated cmd_out_T response waiting; necessary for photo CDs with |
| 243 | * a lot of sessions. |
| 244 | * Bettered the sbpcd_open() behavior with TEAC drives. |
| 245 | * |
| 246 | * 3.8 Elongated max_latency for CR-56x drives. |
| 247 | * |
| 248 | * 3.9 Finally fixed the long-known SoundScape/SPEA/Sequoia S-1000 interface |
| 249 | * configuration bug. |
| 250 | * Now Corey, Heiko, Ken, Leo, Vadim/Eric & Werner are invited to copy |
| 251 | * the config_spea() routine into their drivers. ;-) |
| 252 | * |
| 253 | * 4.0 No "big step" - normal version increment. |
| 254 | * Adapted the benefits from 1.3.33. |
| 255 | * Fiddled with CDROMREADAUDIO flaws. |
| 256 | * Avoid ReadCapacity command with CD200 drives (the MKE 1.01 version |
| 257 | * seems not to support it). |
| 258 | * Fulfilled "read audio" for CD200 drives, with help of Pete Heist |
| 259 | * (heistp@rpi.edu). |
| 260 | * |
| 261 | * 4.1 Use loglevel KERN_INFO with printk(). |
| 262 | * Added support for "Vertos 100" drive ("ECS-AT") - it is very similar |
| 263 | * to the Longshine LCS-7260. Give feedback if you can - I never saw |
| 264 | * such a drive, and I have no specs. |
| 265 | * |
| 266 | * 4.2 Support for Teac 16-bit interface cards. Can't get auto-detected, |
| 267 | * so you have to jumper your card to 0x2C0. Still not 100% - come |
| 268 | * in contact if you can give qualified feedback. |
| 269 | * Use loglevel KERN_NOTICE with printk(). If you get annoyed by a |
| 270 | * flood of unwanted messages and the accompanied delay, try to read |
| 271 | * my documentation. Especially the Linux CDROM drivers have to do an |
| 272 | * important job for the newcomers, so the "distributed" version has |
| 273 | * to fit some special needs. Since generations, the flood of messages |
| 274 | * is user-configurable (even at runtime), but to get aware of this, one |
| 275 | * needs a special mental quality: the ability to read. |
| 276 | * |
| 277 | * 4.3 CD200F does not like to receive a command while the drive is |
| 278 | * reading the ToC; still trying to solve it. |
| 279 | * Removed some redundant verify_area calls (yes, Heiko Eissfeldt |
| 280 | * is visiting all the Linux CDROM drivers ;-). |
| 281 | * |
| 282 | * 4.4 Adapted one idea from tiensivu@pilot.msu.edu's "stripping-down" |
| 283 | * experiments: "KLOGD_PAUSE". |
| 284 | * Inhibited "play audio" attempts with data CDs. Provisions for a |
| 285 | * "data-safe" handling of "mixed" (data plus audio) Cds. |
| 286 | * |
| 287 | * 4.5 Meanwhile Gonzalo Tornaria <tornaria@cmat.edu.uy> (GTL) built a |
| 288 | * special end_request routine: we seem to have to take care for not |
| 289 | * to have two processes working at the request list. My understanding |
| 290 | * was and is that ll_rw_blk should not call do_sbpcd_request as long |
| 291 | * as there is still one call active (the first call will care for all |
| 292 | * outstanding I/Os, and if a second call happens, that is a bug in |
| 293 | * ll_rw_blk.c). |
| 294 | * "Check media change" without touching any drive. |
| 295 | * |
| 296 | * 4.6 Use a semaphore to synchronize multi-activity; elaborated by Rob |
| 297 | * Riggs <rriggs@tesser.com>. At the moment, we simply block "read" |
| 298 | * against "ioctl" and vice versa. This could be refined further, but |
| 299 | * I guess with almost no performance increase. |
| 300 | * Experiments to speed up the CD-55A; again with help of Rob Riggs |
| 301 | * (to be true, he gave both, idea & code. ;-) |
| 302 | * |
| 303 | * 4.61 Ported to Uniform CD-ROM driver by |
| 304 | * Heiko Eissfeldt <heiko@colossus.escape.de> with additional |
| 305 | * changes by Erik Andersen <andersee@debian.org> |
| 306 | * |
| 307 | * 4.62 Fix a bug where playing audio left the drive in an unusable state. |
| 308 | * Heiko Eissfeldt <heiko@colossus.escape.de> |
| 309 | * |
| 310 | * November 1999 -- Make kernel-parameter implementation work with 2.3.x |
| 311 | * Removed init_module & cleanup_module in favor of |
| 312 | * module_init & module_exit. |
| 313 | * Torben Mathiasen <tmm@image.dk> |
| 314 | * |
| 315 | * 4.63 Bug fixes for audio annoyances, new legacy CDROM maintainer. |
| 316 | * Annoying things fixed: |
| 317 | * TOC reread on automated disk changes |
| 318 | * TOC reread on manual cd changes |
| 319 | * Play IOCTL tries to play CD before it's actually ready... sometimes. |
| 320 | * CD_AUDIO_COMPLETED state so workman (and other playes) can repeat play. |
| 321 | * Andrew J. Kroll <ag784@freenet.buffalo.edu> Wed Jul 26 04:24:10 EDT 2000 |
| 322 | * |
| 323 | * 4.64 Fix module parameters - were being completely ignored. |
| 324 | * Can also specify max_drives=N as a setup int to get rid of |
| 325 | * "ghost" drives on crap hardware (aren't they all?) Paul Gortmaker |
| 326 | * |
| 327 | * TODO |
| 328 | * implement "read all subchannel data" (96 bytes per frame) |
| 329 | * remove alot of the virtual status bits and deal with hardware status |
| 330 | * move the change of cd for audio to a better place |
| 331 | * add debug levels to insmod parameters (trivial) |
| 332 | * |
| 333 | * special thanks to Kai Makisara (kai.makisara@vtt.fi) for his fine |
| 334 | * elaborated speed-up experiments (and the fabulous results!), for |
| 335 | * the "push" towards load-free wait loops, and for the extensive mail |
| 336 | * thread which brought additional hints and bug fixes. |

| 4814 | * change every block device.. |
| 4815 | * |
| 4816 | * Could be a race here?? Could e.g. a timer interrupt schedule() us? |

| 4818 | * modify end_request and the block devices). |

| 4824 | * and we are scheduled. Other process takes over, and gets into |
| 4825 | * do_sbpcd_request. It sees CURRENT!=NULL (it is == to our req), so |
| 4826 | * proceeds. It ends, so CURRENT is now NULL.. Now we awake somewhere in |
