2 | * 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. | |
4 | * | |
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 | |
