* Many thanks to Lode Leroy <[email protected]>, 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 <[email protected]> for pointing this out. |
|
* Ver 0.9.sv Jan 6 01 Sam Varshavchik <[email protected]> |
|
* 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 |
|
* <[email protected]> |
|
* 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 |
