6 | * (from mlord) -- minor changes to cdrom_setup() | |
7 | * -- renamed ide_dev_s to ide_drive_t, enable irq on command | |
8 | * 2.00 Nov 27, 1994 -- Generalize packet command interface; | |

13 | * Don't use SCMD_PLAYAUDIO_TI; it's not included | |
14 | * in the current version of ATAPI. | |
15 | * Try to use LBA instead of track or MSF addressing | |
16 | * when possible. | |
17 | * Don't wait for READY_STAT. | |
18 | * 2.03 Jan 10, 1995 -- Rewrite block read routines to handle block sizes | |
19 | * other than 2k and to move multiple sectors in a | |
20 | * single transaction. | |

28 | * Use HWIF and DEV_HWIF macros as in ide.c. | |
29 | * Always try to do a request_sense after | |
30 | * a failed command. | |
31 | * Include an option to give textual descriptions | |
32 | * of ATAPI errors. | |
33 | * Fix a bug in handling the sector cache which | |
34 | * showed up if the drive returned data in 512 byte | |
35 | * blocks (like Pioneer drives). Thanks to | |
36 | * Richard Hirst <srh@gpt.co.uk> for diagnosing this. | |
37 | * Properly supply the page number field in the | |
38 | * MODE_SELECT command. | |
39 | * PLAYAUDIO12 is broken on the Aztech; work around it. | |
40 | * 2.05x Aug 11, 1995 -- lots of data structure renaming/restructuring in ide.c | |

182 | * Jens Axboe <axboe@image.dk> | |
183 | * Chris Zwilling <chris@cloudnet.com> | |
184 | * | |
185 | * 4.51 Dec 23, 1998 -- Jens Axboe <axboe@image.dk> | |
186 | * - ide_cdrom_reset enabled since the ide subsystem | |
187 | * handles resets fine now. <axboe@image.dk> | |
188 | * - Transfer size fix for Samsung CD-ROMs, thanks to | |
189 | * "Ville Hallik" <ville.hallik@mail.ee>. | |
190 | * - other minor stuff. | |
191 | * | |
192 | * 4.52 Jan 19, 1999 -- Jens Axboe <axboe@image.dk> | |
193 | * - Detect DVD-ROM/RAM drives | |
194 | * | |
195 | * 4.53 Feb 22, 1999 - Include other model Samsung and one Goldstar | |
196 | * drive in transfer size limit. | |
197 | * - Fix the I/O error when doing eject without a medium | |
198 | * loaded on some drives. | |
199 | * - CDROMREADMODE2 is now implemented through | |
200 | * CDROMREADRAW, since many drives don't support | |
201 | * MODE2 (even though ATAPI 2.6 says they must). | |
202 | * - Added ignore parameter to ide-cd (as a module), eg | |
203 | * insmod ide-cd ignore='hda hdb' | |
204 | * Useful when using ide-cd in conjunction with | |
205 | * ide-scsi. TODO: non-modular way of doing the | |
206 | * same. | |
207 | * | |
208 | * 4.54 Aug 5, 1999 - Support for MMC2 class commands through the generic | |
209 | * packet interface to cdrom.c. | |
210 | * - Unified audio ioctl support, most of it. | |
211 | * - cleaned up various deprecated verify_area(). | |
212 | * - Added ide_cdrom_packet() as the interface for | |
213 | * the Uniform generic_packet(). | |
214 | * - bunch of other stuff, will fill in logs later. | |
215 | * - report 1 slot for non-changers, like the other | |
216 | * cd-rom drivers. don't report select disc for | |
217 | * non-changers as well. | |
218 | * - mask out audio playing, if the device can't do it. | |
219 | * | |
220 | * 4.55 Sep 1, 1999 - Eliminated the rest of the audio ioctls, except | |
221 | * for CDROMREADTOC[ENTRY|HEADER]. Some of the drivers | |
222 | * use this independently of the actual audio handling. | |
223 | * They will disappear later when I get the time to | |
224 | * do it cleanly. | |
225 | * - Minimize the TOC reading - only do it when we | |
226 | * know a media change has occurred. | |
227 | * - Moved all the CDROMREADx ioctls to the Uniform layer. | |
228 | * - Heiko Eißfeldt <heiko@colossus.escape.de> supplied | |
229 | * some fixes for CDI. | |
230 | * - CD-ROM leaving door locked fix from Andries | |
231 | * Brouwer <Andries.Brouwer@cwi.nl> | |
232 | * - Erik Andersen <andersen@xmission.com> unified | |
233 | * commands across the various drivers and how | |
234 | * sense errors are handled. | |
235 | * | |
236 | * 4.56 Sep 12, 1999 - Removed changer support - it is now in the | |
237 | * Uniform layer. | |
238 | * - Added partition based multisession handling. | |
239 | * - Mode sense and mode select moved to the | |
240 | * Uniform layer. | |
241 | * - Fixed a problem with WPI CDS-32X drive - it | |
242 | * failed the capabilities | |
243 | * | |
244 | * 4.57 Apr 7, 2000 - Fixed sense reporting. | |
245 | * - Fixed possible oops in ide_cdrom_get_last_session() | |
246 | * - Fix locking mania and make ide_cdrom_reset relock | |
247 | * - Stop spewing errors to log when magicdev polls with | |
248 | * TEST_UNIT_READY on some drives. | |
249 | * - Various fixes from Tobias Ringstrom: | |
250 | * tray if it was locked prior to the reset. | |
251 | * - cdrom_read_capacity returns one frame too little. | |
252 | * - Fix real capacity reporting. | |
253 | * | |
254 | * 4.58 May 1, 2000 - Clean up ACER50 stuff. | |
255 | * - Fix small problem with ide_cdrom_capacity | |
256 | * | |
257 | * 4.59 Aug 11, 2000 - Fix changer problem in cdrom_read_toc, we weren't | |
258 | * correctly sensing a disc change. | |
259 | * - Rearranged some code | |
260 | * - Use extended sense on drives that support it for | |
261 | * correctly reporting tray status -- from | |
262 | * Michael D Johnson <johnsom@orst.edu> | |
263 | * 4.60 Dec 17, 2003 - Add mt rainier support | |
264 | * - Bump timeout for packet commands, matches sr | |
265 | * - Odd stuff | |
266 | * 4.61 Jan 22, 2004 - support hardware sector sizes other than 2kB, | |
267 | * Pascal Schmidt <der.eremit@email.de> | |
