|
* - 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 |

|
* 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 |

|
* 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. |
|

|
* some fixes for CDI. |

|
* Brouwer <[email protected]> |
|
* - Erik Andersen <[email protected]> unified |
|
* commands across the various drivers and how |
|
* sense errors are handled. |

|
* 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. |
|
* |

|
* - Fix small problem with ide_cdrom_capacity |
|

|
* correctly reporting tray status -- from |
|
* Michael D Johnson <[email protected]> |
