|
|
* 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.

|
|
|
|
|
* 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
