* Many thanks to Lode Leroy <Lode.Leroy@www.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@es.co.nz> for pointing this out. | |
* Ver 0.9.sv Jan 6 01 Sam Varshavchik <mrsam@courier-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@paulbristow.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 | |
