Subject: [git patches] IDE updates part #3
IDE updates continued...
* ide-cd rewrite (fix few bugs, unify IRQ handlers, re-organize handling
of quirky devices, move verbose error logging / cdrom.c IOCTLs support
to separate files, remove duplicated/dead code and other improvements)
* switch IDE to use generic DMA-mapping API
* IDE probing code revamp
* trm290 host driver fixes
* amd74xx host driver cleanup
* misc stuff
[ + this update shrinks code under drivers/ide/ by almost 1400 LOC :) ]

+ * version, and my own efforts. -erik
+ * -- Fixed a stupid bug which egcs was kind enough to
+ * inform me of where "Illegal mode for this track"
+ * was never returned due to a comparison on data
+ * types of limited range.
+ * 4.12 Mar 29, 1998 -- Fixed bug in CDROM_SELECT_SPEED so write speed is
+ * now set ionly for CD-R and CD-RW drives. I had

+ * Jens Axboe <axboe@...ge.dk>
+ * Chris Zwilling <chris@...udnet.com>
+ *
+ * 4.51 Dec 23, 1998 -- Jens Axboe <axboe@...ge.dk>
+ * - ide_cdrom_reset enabled since the ide subsystem
+ * handles resets fine now. <axboe@...ge.dk>
+ * - Transfer size fix for Samsung CD-ROMs, thanks to
+ * "Ville Hallik" <ville.hallik@...l.ee>.
+ * - other minor stuff.
+ *
+ * 4.52 Jan 19, 1999 -- Jens Axboe <axboe@...ge.dk>
+ * - Detect DVD-ROM/RAM drives
+ *
+ * 4.53 Feb 22, 1999 - Include other model Samsung and one Goldstar
+ * 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@...ossus.escape.de> supplied
+ * some fixes for CDI.

+/*
+ * Many thanks to Lode Leroy <Lode.Leroy@....ibase.be>, who tested so many
+ * ALPHA patches to this driver on an EASYSTOR LS-120 ATAPI floppy drive.
+ *
+ * Ver 0.1 Oct 17 96 Initial test version, mostly based on ide-tape.c.
+ * Ver 0.2 Oct 31 96 Minor changes.
+ * Ver 0.3 Dec 2 96 Fixed error recovery bug.
+ * Ver 0.4 Jan 26 97 Add support for the HDIO_GETGEO ioctl.
+ * Ver 0.5 Feb 21 97 Add partitions support.
+ * Use the minimum of the LBA and CHS capacities.
+ * Avoid hwgroup->rq == NULL on the last irq.
+ * Fix potential null dereferencing with DEBUG_LOG.
+ * Ver 0.8 Dec 7 97 Increase irq timeout from 10 to 50 seconds.
+ * Add media write-protect detection.
+ * Issue START command only if TEST UNIT READY fails.
+ * Add work-around for IOMEGA ZIP revision 21.D.
+ * Remove idefloppy_get_capabilities().
+ * Ver 0.9 Jul 4 99 Fix a bug which might have caused the number of
+ * bytes requested on each interrupt to be zero.
+ * Thanks to <shanos@...co.nz> for pointing this out.
+ * Ver 0.9.sv Jan 6 01 Sam Varshavchik <mrsam@...rier-mta.com>
+ * Implement low level formatting. Reimplemented
+ * IDEFLOPPY_CAPABILITIES_PAGE, since we need the srfp
+ * bit. My LS-120 drive barfs on
+ * IDEFLOPPY_CAPABILITIES_PAGE, but maybe it's just me.
+ * Compromise by not reporting a failure to get this
+ * mode page. Implemented four IOCTLs in order to
+ * implement formatting. IOCTls begin with 0x4600,
+ * 0x46 is 'F' as in Format.
+ * Jan 9 01 Userland option to select format verify.
+ * Added PC_SUPPRESS_ERROR flag - some idefloppy drives
+ * do not implement IDEFLOPPY_CAPABILITIES_PAGE, and
+ * return a sense error. Suppress error reporting in
+ * this particular case in order to avoid spurious
+ * errors in syslog. The culprit is
+ * idefloppy_get_capability_page(), so move it to
+ * idefloppy_begin_format() so that it's not used
+ * unless absolutely necessary.
+ * If drive does not support format progress indication
+ * monitor the dsc bit in the status register.
+ * Also, O_NDELAY on open will allow the device to be
+ * opened without a disk available. This can be used to
+ * open an unformatted disk, or get the device capacity.
+ * Ver 0.91 Dec 11 99 Added IOMEGA Clik! drive support by
+ * <paul@...lbristow.net>
+ * Ver 0.92 Oct 22 00 Paul Bristow became official maintainer for this
+ * driver. Included Powerbook internal zip kludge.
+ * Ver 0.93 Oct 24 00 Fixed bugs for Clik! drive
+ * no disk on insert and disk change now works
+ * Ver 0.94 Oct 27 00 Tidied up to remove strstr(Clik) everywhere
+ * Ver 0.95 Nov 7 00 Brought across to kernel 2.4
+ * Ver 0.96 Jan 7 01 Actually in line with release version of 2.4.0
+ * including set_bit patch from Rusty Russell
+ * Ver 0.97 Jul 22 01 Merge 0.91-0.96 onto 0.9.sv for ac series
+ * Ver 0.97.sv Aug 3 01 Backported from 2.4.7-ac3
+ * Ver 0.98 Oct 26 01 Split idefloppy_transfer_pc into two pieces to
+ * fix a lost interrupt problem. It appears the busy
+ * bit was being deasserted by my IOMEGA ATAPI ZIP 100
+ * drive before the drive was actually ready.
+ * Ver 0.98a Oct 29 01 Expose delay value so we can play.
+ * Ver 0.99 Feb 24 02 Remove duplicate code, modify clik! detection code
+ * to support new PocketZip drives

- * drive in transfer size limit.
- * - Fix the I/O error when doing eject without a medium
- * loaded on some drives.

- * 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.

- * - 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.

- * 4.59 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@...t.edu>
- * 4.60 Dec 17, 2003 - Add mt rainier support
- * - Bump timeout for packet commands, matches sr

*
- * Many thanks to Lode Leroy <Lode.Leroy@....ibase.be>, who tested so many
- * ALPHA patches to this driver on an EASYSTOR LS-120 ATAPI floppy drive.
- *
- * Ver 0.1 Oct 17 96 Initial test version, mostly based on ide-tape.c.
- * Ver 0.2 Oct 31 96 Minor changes.
- * Ver 0.3 Dec 2 96 Fixed error recovery bug.
- * Ver 0.4 Jan 26 97 Add support for the HDIO_GETGEO ioctl.
- * Ver 0.5 Feb 21 97 Add partitions support.
- * Use the minimum of the LBA and CHS capacities.
- * Avoid hwgroup->rq == NULL on the last irq.
- * Fix potential null dereferencing with DEBUG_LOG.
- * Ver 0.8 Dec 7 97 Increase irq timeout from 10 to 50 seconds.
- * Add media write-protect detection.
- * Issue START command only if TEST UNIT READY fails.
- * Add work-around for IOMEGA ZIP revision 21.D.
- * Remove idefloppy_get_capabilities().
- * Ver 0.9 Jul 4 99 Fix a bug which might have caused the number of
- * bytes requested on each interrupt to be zero.
- * Thanks to <shanos@...co.nz> for pointing this out.
- * Ver 0.9.sv Jan 6 01 Sam Varshavchik <mrsam@...rier-mta.com>
- * Implement low level formatting. Reimplemented
- * IDEFLOPPY_CAPABILITIES_PAGE, since we need the srfp
- * bit. My LS-120 drive barfs on
- * IDEFLOPPY_CAPABILITIES_PAGE, but maybe it's just me.
- * Compromise by not reporting a failure to get this
- * mode page. Implemented four IOCTLs in order to
- * implement formatting. IOCTls begin with 0x4600,
- * 0x46 is 'F' as in Format.
- * Jan 9 01 Userland option to select format verify.
- * Added PC_SUPPRESS_ERROR flag - some idefloppy drives
- * do not implement IDEFLOPPY_CAPABILITIES_PAGE, and
- * return a sense error. Suppress error reporting in
- * this particular case in order to avoid spurious
- * errors in syslog. The culprit is
- * idefloppy_get_capability_page(), so move it to
- * idefloppy_begin_format() so that it's not used
- * unless absolutely necessary.
- * If drive does not support format progress indication
- * monitor the dsc bit in the status register.
- * Also, O_NDELAY on open will allow the device to be
- * opened without a disk available. This can be used to
- * open an unformatted disk, or get the device capacity.
- * Ver 0.91 Dec 11 99 Added IOMEGA Clik! drive support by
- * <paul@...lbristow.net>
- * Ver 0.92 Oct 22 00 Paul Bristow became official maintainer for this
- * driver. Included Powerbook internal zip kludge.
- * Ver 0.93 Oct 24 00 Fixed bugs for Clik! drive
- * no disk on insert and disk change now works
- * Ver 0.94 Oct 27 00 Tidied up to remove strstr(Clik) everywhere
- * Ver 0.95 Nov 7 00 Brought across to kernel 2.4
- * Ver 0.96 Jan 7 01 Actually in line with release version of 2.4.0
- * including set_bit patch from Rusty Russell
- * Ver 0.97 Jul 22 01 Merge 0.91-0.96 onto 0.9.sv for ac series
- * Ver 0.97.sv Aug 3 01 Backported from 2.4.7-ac3
- * Ver 0.98 Oct 26 01 Split idefloppy_transfer_pc into two pieces to
- * fix a lost interrupt problem. It appears the busy
- * bit was being deasserted by my IOMEGA ATAPI ZIP 100
- * drive before the drive was actually ready.
- * Ver 0.98a Oct 29 01 Expose delay value so we can play.
- * Ver 0.99 Feb 24 02 Remove duplicate code, modify clik! detection code
- * to support new PocketZip drives
+ * For a historical changelog see
+ * Documentation/ide/ChangeLog.ide-floppy.1996-2002
