He put up with - plenty of silly questions and might get the post of - ambassador some day. - -and The people who donated equipment and other material to make - development of this driver possible. Donations and - sponsors for projects are appreciated. - ------No changes should be needed above this line----------------------------- - -Edit History - (should be in sync with any source control log entries) - - Never seen one of these sections before? Ok, here is how it works. - Every time you change the code, you increment the ANSI 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. - - ANSI version codes have major and minor release numbers. 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 as needed. So 3A(456) is Major release 3, Minor - release 1, Edit 456 (the equivalent in XX.XX.XX version numbering used - by certain monopolies 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 uhclem at freebsd.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-1995 Frank Durda IV uhclem at freebsd.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-1995 Frank Durda IV uhclem at freebsd.org - -<4> Rebundled debug conditionals. - 14-Feb-1995 Frank Durda IV uhclem at freebsd.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-1995 Frank Durda IV uhclem at freebsd.org - -<6> Got rid of some redundant error code by creating chk_error(). - Also built a nice generic bus-lock function. - 20-Feb-1995 Frank Durda IV uhclem at freebsd.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-1995 Frank Durda IV uhclem at freebsd.org - -<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-1995 Frank Durda IV uhclem at freebsd.org - -<9> Added some additional disk-related ioctl functions that didn't - make it into earlier versions. - 26-Feb-1995 Frank Durda IV uhclem at freebsd.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-1995 Frank Durda IV uhclem at freebsd.org - -<11> The Copyright and Use statement has been replaced in all files - with a new version. - 01-Mar-1995 Frank Durda IV uhclem at freebsd.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-1995 Frank Durda IV uhclem at freebsd.org - -<13> Added ioctls to return TOC headers and entries. - 19-Mar-1995 Frank Durda IV uhclem at freebsd.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. - - Complaints about too many comments are noted but that is all. :-) - 21-Mar-1995 Frank Durda IV uhclem at freebsd.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-1995 Frank Durda IV uhclem at freebsd.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. - 04-Apr-1995 Frank Durda IV uhclem at freebsd.org - -<17> The function matcd_toc_entries which is executed in response to - the CDIOREADTOCENTRYS ioctl didn't cope with programs that only - requested part of the TOC. This change is based on code submitted - by Doug Robson (dfr@render.com). - (This change was introduced out of order and exists in FreeBSD - 2.0.5 without the version stamp being updated. I.N.M.F.) - 01-Jun-1995 Frank Durda IV uhclem at freebsd.org - -<18> While working on the TEAC CD-ROM driver (teaccd) that is reusing - chunks of code from this driver, I discovered several functions, - arrays and other things that should have been declared 'static'. - These changes are necessary if the TEAC CD-ROM driver is to be - present at the same time as matcd. - Also fixed the residual buss vs bus symbols and strings. - There are no functional code changes in this edit. - 02-May-1995 Frank Durda IV uhclem at freebsd.org - -<19> Creative has changed the Status port slightly in their - sound boards based on the Vibra-16 (and probably the Vibra-16S) - chipset. This change masks some unused bits that were formally - on all the time and are doing different things in this design. - The changes are transparent to all other supported boards. - 20-Jun-1995 Frank Durda IV uhclem at freebsd.org - -<20> Code was added to detect non-Creative (SoundBlaster) host - interfaces, and the driver will switch to code compatible with the - detected host interface. This should add support for MediaVision, - IBM, Reveal, and other compatible adapters with split - data/status-ports. This code allows a mix of SoundBlaster (Type 0) - and non-SoundBlaster (Type 1) boards in the same system with no - special configuration. - - I also updated the attach code to display the interface type and - changed the host interface probe messages to reflect the "c" for - controller in controller-specific messages as the existing messages - were confusing when a second card was in place . The kernel -c - tables have been updated accordingly, so you now have a matcdc%d - controller to change settings on. - 24-Jun-95 Frank Durda IV uhclem at freebsd.org - -<21> Added interface handling code in two of those "this should not - happen" routines, draincmd and get_stat. Since these routines are - called by functions during probing that may not know what type - interface is out there, the code assumes that a given adapter is - both a type 0 and a type 1 adapter at the same time. Plus, - this code gets executed once in a very long time so the cost of - assuming both host adapter types is not significant. - 04-Jul-1995 Frank Durda IV uhclem at freebsd.org - -<22> Four external interface prototypes were altered by someone else. - I believe these changes are for making GCC and/or the linker shut-up - when building some other part of the system since matcd already - compiles -Wall with no warnings... - 08-Sep-1995 Frank Durda IV uhclem at freebsd.org - -<23> This change implements the ioctls for preventing media removal - and allowing media removal. - Currently, these calls will work according to the following rules: - No "l" devs opened Any "l" dev open - CDALLOW accepted always rejected always - CDPREVENT accepted always accepted always - - One refinement might be to allow CDALLOW/CDPREVENT to always - work if UID 0 issued the ioctl, but that will wait for later. - - I also made a change to the information that the toc_entry code - returns so that xcdplayer won't malfunction. (It would not play - the last track on a non-mixed mode audio CD.) Unlike cdplayer, - xcdplayer asks for track information one track at a time, and - calls for information on the lead-out track by its official - number (0xaa), rather than referring to the "after last" (n+1) track - as cdplayer does. Anyway, this change should make both players - happy. - 16-Sep-1995 Frank Durda IV uhclem at freebsd.org - -<24> In Edit 15 when the extra devs were created for selective locking, - the door locking was broken if a non-locking dev on the drive is - closed. The problem was caused by not tracking locked devs and - non-locking devs as being different partitions. The change is to - simply use the locking dev bit to flag a set of shadow partitions - when it comes to lock operations. All other operations treat the - locked and unlocked partitions as being identical. - 18-Sep-1995 Frank Durda IV uhclem at freebsd.org - -<25> During work on Edit 23, I noted that on slow and very busy systems, - sometimes the driver would go to sleep forever. The problem appears - to have been a race condition caused by doing separate timeout/sleep - calls without using SPL first. The change here is to use tsleep - which provides the equivalent of timeout/sleep timeout/tsleep if the - last paremeter is tsleep is set to the time value that would have been - given to timeout. - I also fixed some duplicate location strings in the tsleep calls. - 24-Sep-1995 Frank Durda IV uhclem at freebsd.org - -<26> Moved a function declaration that generated two warnings with - the FULLCONFIG/FULLDRIVER conditionals disabled. - Updated the igot function so that it correctly reports limited - functions when a sub-set driver is compiled. - Eliminated FULLCONFIG conditional and now set controller counts - based on the NMATCD #define produced by the config process. - Also, disable the audio-related ioctls based on the BOOTMFS - conditional to help make the boot floppy kernel smaller. - 18-Oct-1995 Frank Durda IV uhclem at freebsd.org - -<27> An unknown number of modifications were made by third parties - after edit 26, but they neglected to document everything that - was changed and why. These are known collectively as edit 27. - - All Edit 27 changes were later discarded as part of the creation - of Release 3, as some of the changes became incompatible with - FreeBSD 4.x/5.x, and some broke drive operations that used to work. - January 2003 Frank Durda IV uhclem at freebsd.org - -Begin work on Major Release 3 here - -<28> Begin work on converting the code to run on FreeBSD 5.0. This - included making the driver into a loadable kernel module, and - interfacing with the new port allocator scheme. This code is not - based off what was in 4.6, but comes from the last version I - personally submitted to the project, thus eliminating some fluff that - crept in over the years. The conditionally-compiled sections for - building on pre-FreeBSD 2.0 releases have been removed, as it was - likely not useful to anyone anymore. - - I reclaimed Major device 46 for matcd - it was dropped from the 5.0 - "majors" file - but as of this date it has not been reassigned to - some other device. - 10-Jan-2003 Frank Durda IV uhclem at freebsd.org - -<29> Work to adapt to the new way of passing key settings around between - functions and calls to the driver that seems to be forced on loadable - drivers or perhaps all drivers. This required substantial debugging - as the port addresses identified during probing were not reaching - all the functions that needed that information. - 14-Jan-2003 Frank Durda IV uhclem at freebsd.org - -<30> Work continues, and matcd successfully loads and unloads itself and - creates and cleans up its devs on repeated kldload/kldunloads. - Notice: Because the dev_depends() kernel call for internally linking - multiple devs to a master dev does not appear to exist prior to 5.0 - (was not present in 4.6 or 4.7 releases), the dev create/cleanup - code may not link on older versions, not without commenting out - parts of that section of the driver. See matcd_attach. - 09-Feb-2003 Frank Durda IV uhclem at freebsd.org - -<31> Open() now does everything it is supposed to, and completes - successfully. It isn't clear if disable_intr/enable_intr is - definitely going to prevent the drive commands from being issued - within 10msec, but this seems to be the calls to now use in place - of spl(7)/splx(). - 13-Feb-2003 Frank Durda IV uhclem at freebsd.org - -<32> Strategy code changed to deal with the newer mechanisms for handling - request queues that exists in 5.0. The driver will now mount and - read an ISO filesystem. - 17-Feb-2003 Frank Durda IV uhclem at freebsd.org - -<33> A sweep through the code to eliminate compiler warnings. The code now - produces just one warning in the timeout() call, and so far this one - evades elimination. This edit also started to remove some now-dead - code, unneccessary includes and debug code inserted during the - previous two edits while trying to get basic functions working again. - 22-Feb-2003 Frank Durda IV uhclem at freebsd.org - -<34> Removal of the DIAGPORT code. Although very useful during original - development and for troubleshooting some problems found by others, it - is no longer practical to keep, partly due to the way port allocation - is now handled in FreeBSD, but mostly because of how few motherboards - still have slots that will accomodate these diagnostic cards, most - of which were ISA. This presence of this code, even though ifdef-ed - out in all earlier finished FreeBSD releases, still drove some of - the other developers nuts for unclear reasons, but they should be - happy now... :-) - 02-Mar-2003 Frank Durda IV uhclem at freebsd.org - -<35> Work to make the FULLDRIVER conditional build still compile. This - inserts the audio and special ioctls not needed to be able to perform - simple single-session filesystem mounts, and was used to keep the - boot floppy kernel size down. This work was mainly just re-working - the way our internal data was passed around between functions (See - edit 29), and tracking down declarations that have moved from one - include file to another. Since all the code for talking to the - actual drives worked previously, only the interface back to the rest - of the kernel and calling apps needs any modernization. - 09-Mar-2003 Frank Durda IV uhclem at freebsd.org - -<36> Once work was complete on getting the FULLDRIVER audio functions - compiling again, suddenly we could not mount filesystems anymore. - This was eventually traced to a previously-not-performed-ioctl-call, - now made by some other part of the kernel immediately after an open() - call succeeds. This ioctl reads the TOC for all tracks on the disc. - Who is making this ioctl call (and what the answers are good for) - is not immediately apparent. - - However, when FULLDRIVER wasn't present, this ioctl code was not - available and the driver returned an error to the ioctl, but the mount - succeeded anyway and the filesystem could be used with no issues. - When the ioctl code was there (as a result of FULLDRIVER build), it - was returning the information requested in MSF format, and this was - confusing the caller. - - When matcd was originally written, returning MSF was all that the - original CD audio players ever wanted, but this new mount-time - query wants the answers in LBA format. So the READTOC call has been - updated to return either MSF or LBA formats. Having implemented - that, filesystems can be mounted again. - 16-Mar-2003 Frank Durda IV uhclem at freebsd.org - -<37> Related to Edit 36, when the various ioctls were updated to return - the offset information that was requested in either LBA or MSF - format, that broke the cdcontrol utility, which will request - information (via the "stat" command) in LBA or MSF based on the last - setting of the "set" command, but cdcontrol displays bogus results if - LBA results are returned when cdcontrol asked for them. An - examination of the behavior of the IDE CD-ROM driver shows that for - SUBQ data, the IDE driver ignores the format type in the request and - always returns MSF format, and that seems to be what cdcontrol really - wants, never mind what it asked for. Subsequently, a conditional - (SUBQRETREQUESTED) has been added which will direct the driver to - always return MSF in response to SUBQ queries (default), or to return - what the caller actually asked for. This probably should not be - activated until all other CD-ROM drivers and cdcontrol are fixed - on this point. - 22-Mar-2003 Frank Durda IV uhclem at freebsd.org - -<38> A revisit of the compiler warning on timeout() that just refuses to go - away. A review of other drivers using timeout() suggests that the - way timeout() is used within the kernel has been changed from - traditional calling and passed parameters. This call has no man page - (apparently not even a reference in an include file exists) which - makes confirmation difficult. Further, as the timeout is not used - predictably by the driver (sometimes needed, sometimes not), testing a - change in this area will take some stress/duration testing. - 26-Mar-2003 Frank Durda IV uhclem at freebsd.org - -<39> Two hardware failure conditions were identified when a eight-drive, - two controller configuration was tested. Some types of cable - failure are now detected and reported by the driver. Other failure - modes are documented here for reference: - 1. If the firmware version string displayed during the driver - probing process (normally of the form) "[CR-NNNN.NN]" is - displayed as "[]", or "[ ]" indicates that two or - more drives are jumpered with the same drive select. This - condition may be accompanied by other strange random messages. - - 2. A firmware Version string "[^A^A^A^A^A^A^A^A^A^A]" indicates - that the cable used on the Matsushita drive appears to be - an IDE cable which has a pin pulled out of it (when this is - done, it is usually in the key position). A fully-pinned - cable must be used. A cable with shorts to ground or opens - on numerous lines can also cause this symptom. - - 3. If the driver refuses to go into Idle state, this indicates - a bad cable OR a power-supply under-volt condition. The - drives appear to stay in a Data or Status phase indefinitely - if the supply voltages are below +5 and +12 VDC. The drive - BUSY light may also remain lit continuously or the eject - button may be ignored. - - The rest of this edit was more clean-up and removal of some debug - messages. - 02-Apr-2003 Frank Durda IV uhclem at freebsd.org - -<40> Replaced Copyright text section in all files with the new revisionist - (and vague) one currently required. Everybody should be happy. :-) - 03-Apr-2003 Frank Durda IV uhclem at freebsd.org - -<41> Rebuilt on a stock 5.0-RELEASE platform to look for any issues - that crept in since the late 2002 snapshot I had been using and - to verify functionality on a dual-processor system. - - Changed the ioctl for eject so that it would work when there was - no media in the drive. The way it was seemed obviously wrong, but no - one had said anything about this behavior in all the years it has - worked that way. - - Also discovered that some of the ioctls failed to lock the device - prior to issuing commands, and this could cause other operations - to that same drive to not start and hang forever. Example, - "strings /dev" on one process while another issues an eject. Yes, - the "strings" will end up getting an error, but that is what should - happen, not having "strings" simply stop and never come back. - 18-Apr-2003 Frank Durda IV uhclem at freebsd.org - -<42> Changes to make matcd.c compile again on a 6-May-2003 pre-Beta 5.1 - cvsup, as the deck chairs continue to shift. - o Dropped tests for DIOCWLABEL on reads, which is now undefined. - o bioqdisksort() in the kernel depths changed its name from 5.0.* - o bounds_check_with_label() kernel call disappeared since 5.0 - with no apparent replacement.* - o The way the cdevsw structure is done has changed for the nth - time.
