18 ----------------------------------
19 1.00 Date Unknown -- David van Leeuwen <david@tm.tno.nl>
20 -- Initial version by David A. van Leeuwen. I don't have a detailed
23 2.00 Dec 2, 1997 -- Erik Andersen <andersee@debian.org>
24 -- New maintainer! As David A. van Leeuwen has been too busy to actively
28 -- Added (rudimentary) sysctl interface. I realize this is really weak
31 -- Modified CDROM_DISC_STATUS so that it is now incorporated into
32 the Uniform CD-ROM driver via the cdrom_count_tracks function.
37 -- Remove the calls to verify_area and only use the copy_from_user and
41 -- Major update to return codes so that errors from low-level drivers
45 -- Made it so if a function isn't implemented in a low-level driver,
48 -- Simplified some complex logic so that the source code is easier to read.
50 -- Other stuff I probably forgot to mention (lots of changes).
52 2.01 to 2.11 Dec 1997-Jan 1998
53 -- TO-DO! Write changelogs for 2.01 to 2.12.
55 2.12 Jan 24, 1998 -- Erik Andersen <andersee@debian.org>
56 -- Fixed a bug in the IOCTL_IN and IOCTL_OUT macros. It turns out that
58 of bytes not copied. I was returning whatever non-zero stuff came back from
61 2.13 July 17, 1998 -- Erik Andersen <andersee@debian.org>
62 -- Fixed a bug in CDROM_SELECT_SPEED where you couldn't lower the speed
65 -- Fixed the procfs-unload-module bug with the fill_inode procfs callback.
67 -- Fixed it so that the /proc entry now also shows up when cdrom is
70 2.14 August 17, 1998 -- Erik Andersen <andersee@debian.org>
71 -- Fixed a bug in cdrom_media_changed and handling of reporting that
74 -- Made a few things more pedanticly correct.
76 2.50 Oct 19, 1998 - Jens Axboe <axboe@image.dk>
77 -- New maintainers! Erik was too busy to continue the work on the driver,
81 2.51 Dec 20, 1998 - Jens Axboe <axboe@image.dk>
82 -- Check if drive is capable of doing what we ask before blindly changing
83 cdi->options in various ioctl.
84 -- Added version to proc entry.
86 2.52 Jan 16, 1999 - Jens Axboe <axboe@image.dk>
87 -- Fixed an error in open_for_data where we would sometimes not return
89 -- Fixed module usage count - usage was based on /proc/sys/dev
91 modules had entries in dev. Feb 02 - real bug was in sysctl.c where
95 2.53 Feb 22, 1999 - Jens Axboe <axboe@image.dk>
96 -- Fixup of several ioctl calls, in particular CDROM_SET_OPTIONS has
99 -- Added CDROM_LOCKDOOR ioctl. Locks the door and keeps it that way.
100 -- Added CDROM_RESET ioctl.
101 -- Added CDROM_DEBUG ioctl. Enable debug messages on-the-fly.
102 -- Added CDROM_GET_CAPABILITY ioctl. This relieves userspace programs
105 2.54 Mar 15, 1999 - Jens Axboe <axboe@image.dk>
106 -- Check capability mask from low level driver when counting tracks as
109 2.55 Apr 25, 1999 - Jens Axboe <axboe@image.dk>
110 -- autoclose was mistakenly checked against CDC_OPEN_TRAY instead of
112 -- proc info didn't mask against capabilities mask.
114 3.00 Aug 5, 1999 - Jens Axboe <axboe@image.dk>
115 -- Unified audio ioctl handling across CD-ROM drivers. A lot of the
118 -- First attempt at adding support for MMC2 commands - for DVD and
119 CD-R(W) drives. Only the DVD parts are in now - the interface used is
121 -- ioctl cleanups. if a drive couldn't play audio, it didn't get
123 -- Defined CDROM_CAN(CDC_XXX) for checking the capabilities.
124 -- Put in sysctl files for autoclose, autoeject, check_media, debug,
126 -- /proc/sys/dev/cdrom/info has been updated to also contain info about
127 CD-Rx and DVD capabilities.
128 -- Now default to checking media type.
129 -- CDROM_SEND_PACKET ioctl added. The infrastructure was in place for
132 3.01 Aug 6, 1999 - Jens Axboe <axboe@image.dk>
133 -- Fix up the sysctl handling so that the option flags get set
135 -- Fix up ioctl handling so the device specific ones actually get
138 3.02 Aug 8, 1999 - Jens Axboe <axboe@image.dk>
139 -- Fixed volume control on SCSI drives (or others with longer audio
141 -- Fixed a couple of DVD minors. Thanks to Andrew T. Veliath
144 DVD patches for ide-cd and while I rearranged and unified them, the
147 3.03 Sep 1, 1999 - Jens Axboe <axboe@image.dk>
148 -- Moved the rest of the audio ioctls from the CD-ROM drivers here. Only
150 -- Moved the CDROMREADxxx ioctls in here.
151 -- Defined the cdrom_get_last_written and cdrom_get_next_block as ioctls
153 -- Erik Andersen <andersen@xmission.com> modified all SCMD_ commands
156 -- Various other cleanups.
158 3.04 Sep 12, 1999 - Jens Axboe <axboe@image.dk>
159 -- Fixed a couple of possible memory leaks (if an operation failed and
160 we didn't free the buffer before returning the error).
161 -- Integrated Uniform CD Changer handling from Richard Sharman
163 -- Defined CD_DVD and CD_CHANGER log levels.
164 -- Fixed the CDROMREADxxx ioctls.
165 -- CDROMPLAYTRKIND uses the GPCMD_PLAY_AUDIO_MSF command - too few
167 -- Small modifications to accommodate opens of /dev/hdc1, required
168 for ide-cd to handle multisession discs.
169 -- Export cdrom_mode_sense and cdrom_mode_select.
170 -- init_cdrom_command() for setting up a cgc command.
172 3.05 Oct 24, 1999 - Jens Axboe <axboe@image.dk>
173 -- Changed the interface for CDROM_SEND_PACKET. Before it was virtually
175 -- Lowered stack usage in mmc_ioctl(), dvd_read_disckey(), and
177 -- Added setup of write mode for packet writing.
178 -- Fixed CDDA ripping with cdda2wav - accept much larger requests of
181 3.06 Dec 13, 1999 - Jens Axboe <axboe@image.dk>
182 -- Added support for changing the region of DVD drives.
183 -- Added sense data to generic command.
185 3.07 Feb 2, 2000 - Jens Axboe <axboe@suse.de>
186 -- Do same "read header length" trick in cdrom_get_disc_info() as
187 we do in cdrom_get_track_info() -- some drive don't obey specs and
189 -- Deleted stuff related to setting up write modes. It has a different
191 -- Clear header length in mode_select unconditionally.
192 -- Removed the register_disk() that was added, not needed here.
194 3.08 May 1, 2000 - Jens Axboe <axboe@suse.de>
195 -- Fix direction flag in setup_send_key and setup_report_key. This
197 -- Always return -EROFS for write opens
198 -- Convert to module_init/module_exit style init and remove some
200 -- Fix several dvd errors - DVD_LU_SEND_ASF should pass agid,
201 DVD_HOST_SEND_RPC_STATE did not set buffer size in cdb, and
203 did not clear a 0 sized buffer.
205 3.09 May 12, 2000 - Jens Axboe <axboe@suse.de>
206 -- Fix Video-CD on SCSI drives that don't support READ_CD command. In
210 3.10 Jun 10, 2000 - Jens Axboe <axboe@suse.de>
211 -- Fix volume control on CD's - old SCSI-II drives now use their own
