mycroft 5f478330e8 Remove now-bogus casts. 1994-05-05 08:31:00 +00:00
cgd a0a7429482 lots of changes: prototype migration, move lots of variables, definitions,
and structure elements around.  kill some unnecessary type and macro
definitions.  standardize clock handling.  More changes than you'd want.

mycroft 8ccc7bdffb Turn off the timeout debugging info by default. 1994-03-30 04:58:32 +00:00
mycroft 592ec61b17 Updates for new autoconfig. 1994-03-29 04:35:37 +00:00
mycroft fe3d0b99c3 Prefix the busy-wait messages with `ignore this:' so people stop reporting
it as a bug.
1994-03-12 22:36:40 +00:00
mycroft 9ab5683dc7 Fix problem with reading the disk label if it's not at the beginning of the
disk.
1994-03-12 22:32:48 +00:00
mycroft 15d758c39a Remove backward compatibility hacks for config(8), as they are no longer
useful.
1994-03-12 03:45:03 +00:00
mycroft d884f7c425 Update to match config(8). 1994-03-12 03:34:02 +00:00
mycroft 119f3ea688 Various:
Put WDF_ERROR in the wdc_softc, to avoid gratuitously forcing non-active drives
into single-sector mode on the next transfer.  Arrange to wait for an interrupt
after wdsetctlr(); this avoids long busy-wait delays, and gets rid of the
`extra interrupt' messages (except for one immediately after autoconfig on some
machines).  Replace some uses of wdsetctlr() with simply lowering wd->sc_state;
no point in forcing this immediately.  Allow control operations to time out.
Enable the warnings for long busy-wait delays by default.  Some other minor
things not worth mentioning.
1994-03-11 23:29:12 +00:00
mycroft 99dbc0692d Add a heuristic for detecting old config(8)s. This is very temporary. 1994-03-10 22:30:06 +00:00
mycroft 390f5990bb Now that the disk probe routines are actually called, they need to return
something.

mycroft 0c19458c6f More updates for new config. 1994-03-10 20:05:30 +00:00
mycroft aa45779df7 Update for new config. 1994-03-10 19:57:20 +00:00
mycroft e4102b8797 Cleanup to fit standard coding conventions, and *many* bugs fixed. 1994-03-10 05:18:33 +00:00
mycroft 5a17003403 Some changes inspired by Bruce Evans's driver:
Consolidate error reporting in one function.  Actually use the dk_status and
dk_error fields, and pass around only the error bit to avoid lots of unneeded
assignments and tests.  No functional differences.
1994-03-07 05:54:44 +00:00
mycroft 991225bfc8 Remove DKFL_QUIET. 1994-03-07 03:18:35 +00:00
mycroft 0c082bcaf8 DELAY() --> delay(). This is not a macro. 1994-03-06 17:18:43 +00:00
mycroft 87ed28e74e Move the drive select and various other things into wdcommand(), to avoid
duplicating code.
1994-03-05 08:17:06 +00:00
mycroft 3e02952c52 Make sure we clear the interrupt when necessary. Why this isn't needed on
my hardware is a mystery.
1994-03-04 23:43:14 +00:00
mycroft 652712272f Add another missing splx(). 1994-03-04 17:51:10 +00:00
mycroft 0f92f76ceb Remember to splx() on some error conditions. 1994-03-04 17:45:22 +00:00
mycroft ef3c1bf7e6 Start the timeout loop *after* we've decided there is a disk there. 1994-03-04 04:15:24 +00:00
mycroft 220512c2a8 De-ANSIfy. Move the timeout counter into struct disk. Remove unneeded args
to wd[gs]etctlr().  Other minor changes.
1994-03-04 03:43:48 +00:00

minor cleanup.

mycroft 21118b1bc4 Don't busy-wait for read or write completion. 1994-03-02 22:07:00 +00:00
mycroft e9326b3ba7 Make wdc_wait() do an implicit wait_for_unbusy(). Pass structure pointers
rahter than unit numbers where appropriate.  Fix conflict if two drives have
I/O pending at the same time.  Add some more sanity checks.  Some other minor
cleanup.
1994-03-02 21:42:31 +00:00
mycroft 8ba740e6ab Get the residual count right. 1994-02-26 19:49:25 +00:00
mycroft 060ee7dbab Clean up busy-wait code a little, and we need a special disksort() to skip
over bufs in a combined transfer.
