Just as I was finishing Edit 16, I discovered that there + may be a way to cause a drive to go "offline", allowing the host + to send a command to one or more other drives on the same + interface, similar to the SCSI disconnect mechanism. The changes + to the driver to take advantage of this aren't huge, but will have + to wait until after 2.1. Too much risk of breaking something. + Unless you have multiple drives, you won't see a difference. + +2. Someone wants to switch all drivers from disklabel and + its assorted mechanisms over to disk slicing and its mechanisms, + but I was unable to find any useful documentation on how to + implement the changes for a read-only, single-partition, + removable (ie, partition can change size) device. + So this will have to wait until after 2.1. + +3. Support for reading R-W subcodes while playing audio. This would be + useful if you have any CD+G or CD+MIDI discs, but the demand for this + is pretty low, unless you like Karaoke. Someone will also have to + write a CD+G viewer for X. The code for the driver to add this is + pretty minor but there aren't any precedents on how to handle the + data transfer to the application. + +4. Support for reading the ISBN and UPC labels. The ioctl structures + for these appear to be defined but no other driver seems to do this. + +5. Multi-session support. There are two forms of this; what + Philips defined and what Kodak uses. This will be quite + complicated and will probably require changes in the filesystem + layer. The drive support for Kodak multi-session is known to work. + +6. Multiple data tracks. My vision here was to add an ioctl + that caused a track offset to be inserted into block requests, + effectively shifting the base to the specified track. Very + easy to add but not a big deal since I have only two discs + in my collection that have multiple data tracks and I mastered + one of them. + +7. A curses-based CD-Player app (ie, not X). I will probably do this + mainly for its value as a debugging tool. It was pretty annoying + not finding a single application that actually issued all the + defined ioctls, let alone any new ones. + +If you feel the urge to work on one or more of these remaining items, +please contact the author first at bsdmail@nemesis.lonestar.org +to make sure the work hasn't already been done or started. + + Frank Durda IV + diff --git a/sys/i386/isa/matcd/audio.c b/sys/i386/isa/matcd/audio.c new file mode 100644 index 0000000..837689a --- /dev/null +++ b/sys/i386/isa/matcd/audio.c @@ -0,0 +1,514 @@ +/*audio.c-------------------------------------------------------------------- + + Matsushita(Panasonic) / Creative CD-ROM Driver (matcd) + Authored by Frank Durda IV + + Copyright 1994, 1995 Frank Durda IV.

Donations and + sponsors for projects are appreciated. + + +-----No changes are allowed above this line------------------------------------ + +Edit History - (should be in sync with any source control log entries) + + Never seen one of these before? Ok, here is how it works. + Every time you change the code, you increment the edit number, + that number over there in the <%d> and in the (%d) in the + version string. You never set this number lower than it is. + Near, or preferably on lines that change, insert the edit + number. If there is a number there already, you can replace it + with a newer one. This makes searches for code changes very fast. + + In the edit history, start with the edit number, and a good + description of what changes were made. Then follow it with + the date, your name and an EMAIL address where you can be reached. + + Please follow this practice; it helps leave understandable code in + your wake. + + FYI, you have major and minor release codes. Major releases numbered + 1 thru n. Major feature additions should get a new major release + number. Minor releases start with a null and then letters + A thru Z. So 3A(456) is Major release 3, Minor release 1, + Edit 456 (in Microsoft-ese that would be 03.01.456), and 5(731) + is Major release 5, Minor release 0, Edit 731. Typically only the + author will change the major and minor release codes in small + projects. + + EDIT edit Edit HISTORY history History + +<1> This initial version is to get basic filesystem I/O working + using the SoundBlaster 16 interface. The stand-alone adapter + card doesn't work yet. + December 1994 Frank Durda IV bsdmail@nemesis.lonestar.org + +<2> Corrections to resolve a race condition when multiple drives + on the same controller was active. Fixed drive 1 & 2 swap + problem. See selectdrive(). + 21-Jan-95 Frank Durda IV bsdmail@nemesis.lonestar.org + +<3> Added automatic probing and support for all Creative Labs sound + cards with the Creative/Panasonic interface and the stand-alone + interface adapters. See AUTOHUNT and FULLCONFIG conditionals + for more information. + 21-Jan-95 Frank Durda IV bsdmail@nemesis.lonestar.org + +<4> Rebundled debug conditionals. + 14-Feb-95 Frank Durda IV bsdmail@nemesis.lonestar.org + +<5> Changes needed to work on FreeBSD 2.1. Also added draincmd + since some conditions cause the drive to produce surprise data. + See setmode and draincmd + 19-Feb-95 Frank Durda IV bsdmail@nemesis.lonestar.org + +<6> Got rid of some redundant error code by creating chk_error(). + Also built a nice generic bus-lock function. + 20-Feb-95 Frank Durda IV bsdmail@nemesis.lonestar.org + +<7> Improved comments, general structuring. + Fixed a problem with disc eject not working if LOCKDRIVE was set. + Apparently the drive will reject an EJECT command if the drive + is LOCKED. + 21-Feb-95 Frank Durda IV bsdmail@nemesis.lonestar.org + +Edit number code marking begins here - earlier edits were during development. + +<8> Final device name selected and actually made to compile under + >2.0. For newer systems, it is "matcd", for older it is "mat". + 24-Feb-95 Frank Durda IV bsdmail@nemesis.lonestar.org + +<9> Added some additional disk-related ioctl functions that didn't + make it into earlier versions. + 26-Feb-95 Frank Durda IV bsdmail@nemesis.lonestar.org + +<10> Updated some conditionals so the code will compile under + 1.1.5.1, although this is not the supported platform. + Also found that some other devices probe code was changing the + settings for the port 0x302 debug board, so added code to set it + to a sane state before we use it. + 26-Feb-95 Frank Durda IV bsdmail@nemesis.lonestar.org + +<11> The Copyright and Use statement has been replaced in all files + with a new version. + 1-Mar-95 Frank Durda IV bsdmail@nemesis.lonestar.org + +<12> Added ioctls having to do with audio volume, routing and playback + speed. Also added some code I think is for dynamic loading. + 12-Mar-95 Frank Durda IV bsdmail@nemesis.lonestar.org + +<13> Added ioctls to return TOC headers and entries. + 19-Mar-95 Frank Durda IV bsdmail@nemesis.lonestar.org + +<14> More ioctls to finish out general audio support and some clean-up. + Also fixed a bug in open where CD label information would not + always be cleared after a disc change. + + Added a check to block attempts to resume audio if already playing. + The resulting sound is a cross between Kryten and Max Headroom. + But, if you *want* this "feature", enable #define KRYTEN + in options.h. + + So it is not BSD-ish enough, eh? What, too many comments? :-) + 21-Mar-95 Frank Durda IV bsdmail@nemesis.lonestar.org + +<15> LOCKDRIVE has been modified so that a new series of minor + numbers are created. When these are opened, the selected + drive will have its door locked and the device must be completely + closed to unlock the media. The EJECT ioctl will be refused + when the drive is locked this way. This is useful for + servers and other places where the media needs to remain in the + drive. Bit 7 of the minor number controls locking. + + As of this edit, the code compiles with no warnings with -Wall set. + 22-Mar-95 Frank Durda IV bsdmail@nemesis.lonestar.org + +<16> Added a new check in the probe code that looks for the drive + interface being in an idle state after issuing a reset. If this + isn't the case, then the device at this location isn't a + Matsushita CD-ROM drive. This will prevent hangs in draincmd later. + Added the tray close ioctl. This required modifications to open + to allow the character devices to be "partially" opened so that + the close ioctl could be issued when the open would otherwise fail. + Close also delays slightly after completing because the drive + doesn't update its disc and media status instantly. + Also created the capability ioctl that lets an application find out + up front what things a drive can do. + Fixed a global spelling error. + Changed matcddriver structure to simply say "matcd". The original + string "matcd interface " broke the kernel -c boot mechanism. + Updated the #includes in response to a complaint in first release. + Updated and tested conditionals so that driver will still compile + under FreeBSD 1.1.5.1 as well as 2.0 and early 2.1. + 4-Apr-95 Frank Durda IV bsdmail@nemesis.lonestar.org + +---------------------------------------------------------------------------*/ + +/*Match this format: Version_dc(d)__dd-mmm-yy */ +static char MATCDVERSION[]="Version 1(16) 4-Apr-95";
