| 37 | * Properly supply the page number field in the |
| 38 | * MODE_SELECT command. |

Bartlomiej Zolnierkiewicz | 0355335 | 2008-02-01 23:09:18 +0100 | [diff] [blame] | 179 | * patch thanks to "Eddie C. Dost" <ecd@skynet.be> |
| 180 | * |
| 181 | * 4.50 Oct 19, 1998 -- New maintainers! |
| 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> |
