| * Make VERBOSE_IDE_CD_ERRORS dump failed command again. | |
| * Dump out more information for ILLEGAL REQUEST errs. | |
| * Fix handling of errors occurring before the | |
| * packet command is transferred. | |
| * Fix transfers with odd bytelengths. | |
| * 3.03 Oct 27, 1995 -- Some Creative drives have an id of just `CD'. | |

| * patch thanks to "Eddie C. Dost" <ecd@skynet.be> | |
| * | |
| * 4.50 Oct 19, 1998 -- New maintainers! | |
| * Jens Axboe <axboe@image.dk> | |
| * Chris Zwilling <chris@cloudnet.com> | |
| * | |
| * 4.51 Dec 23, 1998 -- Jens Axboe <axboe@image.dk> | |
| * - ide_cdrom_reset enabled since the ide subsystem | |
| * handles resets fine now. <axboe@image.dk> | |
| * - Transfer size fix for Samsung CD-ROMs, thanks to | |
| * "Ville Hallik" <ville.hallik@mail.ee>. | |
| * - other minor stuff. | |
| * | |

| * - Detect DVD-ROM/RAM drives | |
| * | |

| * drive in transfer size limit. | |
| * - Fix the I/O error when doing eject without a medium | |
| * loaded on some drives. | |
| * - CDROMREADMODE2 is now implemented through | |
| * CDROMREADRAW, since many drives don't support | |
| * MODE2 (even though ATAPI 2.6 says they must). | |
| * - Added ignore parameter to ide-cd (as a module), eg | |
| * insmod ide-cd ignore='hda hdb' | |
| * Useful when using ide-cd in conjunction with | |
| * ide-scsi. TODO: non-modular way of doing the | |
| * same. | |
| * | |
| * 4.54 Aug 5, 1999 - Support for MMC2 class commands through the generic | |
| * packet interface to cdrom.c. | |
| * - Unified audio ioctl support, most of it. | |
| * - cleaned up various deprecated verify_area(). | |
| * - Added ide_cdrom_packet() as the interface for | |
| * the Uniform generic_packet(). | |
| * - bunch of other stuff, will fill in logs later. | |
| * - report 1 slot for non-changers, like the other | |
| * cd-rom drivers. don't report select disc for | |
| * non-changers as well. | |
| * - mask out audio playing, if the device can't do it. | |
| * | |
| * 4.55 Sep 1, 1999 - Eliminated the rest of the audio ioctls, except | |
| * for CDROMREADTOC[ENTRY|HEADER]. Some of the drivers | |
| * use this independently of the actual audio handling. | |
| * They will disappear later when I get the time to | |
| * do it cleanly. | |
| * - Minimize the TOC reading - only do it when we | |
| * know a media change has occurred. | |
| * - Moved all the CDROMREADx ioctls to the Uniform layer. | |
| * - Heiko Eißfeldt <heiko@colossus.escape.de> supplied | |
| * some fixes for CDI. | |
| * - CD-ROM leaving door locked fix from Andries | |
| * Brouwer <Andries.Brouwer@cwi.nl> | |
| * - Erik Andersen <andersen@xmission.com> unified | |
| * commands across the various drivers and how | |
| * sense errors are handled. | |
| * | |
| * 4.56 Sep 12, 1999 - Removed changer support - it is now in the | |
| * Uniform layer. | |
| * - Added partition based multisession handling. | |
| * - Mode sense and mode select moved to the | |
| * Uniform layer. | |
| * - Fixed a problem with WPI CDS-32X drive - it | |
| * failed the capabilities | |
| * | |
| * 4.57 Apr 7, 2000 - Fixed sense reporting. | |
| * - Fixed possible oops in ide_cdrom_get_last_session() | |
| * - Fix locking mania and make ide_cdrom_reset relock | |
| * - Stop spewing errors to log when magicdev polls with | |
| * TEST_UNIT_READY on some drives. | |
| * - Various fixes from Tobias Ringstrom: | |
| * tray if it was locked prior to the reset. | |
| * - cdrom_read_capacity returns one frame too little. | |
| * - Fix real capacity reporting. | |
| * | |
| * 4.58 May 1, 2000 - Clean up ACER50 stuff. | |
| * - Fix small problem with ide_cdrom_capacity | |
| * | |
| * 4.59 Aug 11, 2000 - Fix changer problem in cdrom_read_toc, we weren't | |
| * correctly sensing a disc change. | |
| * - Rearranged some code | |
| * - Use extended sense on drives that support it for | |
| * correctly reporting tray status -- from | |
| * Michael D Johnson <johnsom@orst.edu> | |
| * 4.60 Dec 17, 2003 - Add mt rainier support | |
| * - Bump timeout for packet commands, matches sr | |
| * - Odd stuff | |
