* Chris Zwilling <chris@cloudnet.com> | |
* | |
* 4.51 Dec 23, 1998 -- Jens Axboe <axboe@image.dk> | |

* 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 | |
