  1. /*
  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
