/* * 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 */
