| * 4.15 Aug 25, 1998 -- Updated ide-cd.h to respect mechine endianess, | ||
| * 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. | ||
| * | ||
| * 4.52 Jan 19, 1999 -- Jens Axboe <axboe@image.dk> | ||
| * - Detect DVD-ROM/RAM drives | ||
| * | ||
| * 4.53 Feb 22, 1999 - Include other model Samsung and one Goldstar | ||
| * 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 | ||
| * 4.61 Jan 22, 2004 - support hardware sector sizes other than 2kB, | ||
