* Many thanks to Lode Leroy <Lode.Leroy@www.ibase.be>, who tested so many
3
* ALPHA patches to this driver on an EASYSTOR LS-120 ATAPI floppy drive.
5
* Ver 0.1 Oct 17 96 Initial test version, mostly based on ide-tape.c.
6
* Ver 0.2 Oct 31 96 Minor changes.
7
* Ver 0.3 Dec 2 96 Fixed error recovery bug.
8
* Ver 0.4 Jan 26 97 Add support for the HDIO_GETGEO ioctl.
9
* Ver 0.5 Feb 21 97 Add partitions support.
10
* Use the minimum of the LBA and CHS capacities.
11
* Avoid hwgroup->rq == NULL on the last irq.
12
* Fix potential null dereferencing with DEBUG_LOG.
13
* Ver 0.8 Dec 7 97 Increase irq timeout from 10 to 50 seconds.
14
* Add media write-protect detection.
15
* Issue START command only if TEST UNIT READY fails.
16
* Add work-around for IOMEGA ZIP revision 21.D.
17
* Remove idefloppy_get_capabilities().
18
* Ver 0.9 Jul 4 99 Fix a bug which might have caused the number of
19
* bytes requested on each interrupt to be zero.
20
* Thanks to <shanos@es.co.nz> for pointing this out.
21
* Ver 0.9.sv Jan 6 01 Sam Varshavchik <mrsam@courier-mta.com>
22
* Implement low level formatting. Reimplemented
23
* IDEFLOPPY_CAPABILITIES_PAGE, since we need the srfp
24
* bit. My LS-120 drive barfs on
25
* IDEFLOPPY_CAPABILITIES_PAGE, but maybe it's just me.
26
* Compromise by not reporting a failure to get this
27
* mode page. Implemented four IOCTLs in order to
28
* implement formatting. IOCTls begin with 0x4600,
29
* 0x46 is 'F' as in Format.
30
* Jan 9 01 Userland option to select format verify.
31
* Added PC_SUPPRESS_ERROR flag - some idefloppy drives
32
* do not implement IDEFLOPPY_CAPABILITIES_PAGE, and
33
* return a sense error. Suppress error reporting in
34
* this particular case in order to avoid spurious
35
* errors in syslog. The culprit is
36
* idefloppy_get_capability_page(), so move it to
37
* idefloppy_begin_format() so that it's not used
38
* unless absolutely necessary.
39
* If drive does not support format progress indication
40
* monitor the dsc bit in the status register.
41
* Also, O_NDELAY on open will allow the device to be
42
* opened without a disk available. This can be used to
43
* open an unformatted disk, or get the device capacity.
44
* Ver 0.91 Dec 11 99 Added IOMEGA Clik! drive support by
45
* <paul@paulbristow.net>
46
* Ver 0.92 Oct 22 00 Paul Bristow became official maintainer for this
47
* driver. Included Powerbook internal zip kludge.
48
* Ver 0.93 Oct 24 00 Fixed bugs for Clik! drive
49
* no disk on insert and disk change now works
50
* Ver 0.94 Oct 27 00 Tidied up to remove strstr(Clik) everywhere
51
* Ver 0.95 Nov 7 00 Brought across to kernel 2.4
52
* Ver 0.96 Jan 7 01 Actually in line with release version of 2.4.0
53
* including set_bit patch from Rusty Russell
54
* Ver 0.97 Jul 22 01 Merge 0.91-0.96 onto 0.9.sv for ac series
55
* Ver 0.97.sv Aug 3 01 Backported from 2.4.7-ac3
56
* Ver 0.98 Oct 26 01 Split idefloppy_transfer_pc into two pieces to
57
* fix a lost interrupt problem. It appears the busy
58
* bit was being deasserted by my IOMEGA ATAPI ZIP 100
59
* drive before the drive was actually ready.
60
* Ver 0.98a Oct 29 01 Expose delay value so we can play.
61
* Ver 0.99 Feb 24 02 Remove duplicate code, modify clik! detection code
62
* to support new PocketZip drives
