David Greenman 3a2f7427fe Updated driver to the 1.1.5 version:
date: 1994/05/22 12:35:38;  author: joerg;  state: Exp;  lines: +6 -6
First round of floppy changes. Try making `fd' more robust.

New features:
  .  ioctl command for setting the drive type (density etc.); restricted
     to the super-user
  .  ioctl for getting/seting `drive options'; currently only option
     is FDOPT_NORETRY: inhibit the usual retries; used when verifying
     a newly formatted track

Fixes:
  .  function prototypes
  .  made all internal functions `static'
  .  cleaned up & corrected .h files
  .  restructured, to make the chaotic function sequence more rational
  .  compiled with -Wall, and cleared all warnings
  .  introduced a mirror for the (write-only) `digital output register',
     to avoid the current kludge
  .  device probing completed by seeking/recalibrating, and looking
     for track 0 being found
  .  holding the controller down in reset state while it is idle (and
     thus saving allot of headaches)
  .  make requests fail that are not a multiple of the (physical)
     sector size
  .  removed the fixed physical sector size (512 bytes), allowing for any
     size the controller could handle (128/256/512/1024 bytes)
  .  replaced some silly messages
  .  fixed the TRACE* macro usage, debugging reports should be complete
     now again (debugging output is HUGE! though)
  .  removed fd_timeout for SEEK command; seeks are always reported by
     the controller to succeed, since the `success' only refers to the
     controller's idea of success - there is no hardware line to tell about
     the seek end (other than the `track 0' line)
  .  catch SENSEI's that report about a `terminated due to READY changed'
     status - could happen after a controller reset
  .  converted ``hz / <something>'' divide operations to divisors that are
     powers of two, so gcc can optimize them into shifts
  .  write/format operations are checked against a write-protected medium
     now *prior* starting the operation
  .  error reports of `invalid command' and `wrong cylinder' will cause
     shortcuts in the retrier() now
  .  fixed a bug in the retrier() causing bogus block numbers to be reported
  .  fdformat() does care for errors now

Known Bugs:
  .  no attempts have been made (yet) to improve the performance
  .  sometimes, bogus ``seek/recalib failed'' messages are logged; this
     is still a bug in the driver, but it's not harmful since it's
     usually caught by the retrier()
