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.
1994-03-10 21:52:07 +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

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 220512c2a8 De-ANSIfy. Move the timeout counter into struct disk. Remove unneeded args

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 060ee7dbab Clean up busy-wait code a little, and we need a special disksort() to skip
over bufs in a combined transfer.

cgd 55a9a547a2 from Soeren Schmidt <sos@login.dkuug.dk>:
Basically it does a timeout on lost interrupts, starting the operation
again and logging and error message on the console.
additionally fixes some of the (newer ending) while loops
(that made it work with two IDE disks !)
1993-12-13 10:16:56 +00:00

deraadt 80dc38edb3 documentation error 1993-07-08 08:22:17 +00:00
deraadt 9bff90a5c1 added a timeout debugging mode to wd.c so that people can see how slow
their controllers really are. Look for the WDCNDELAY_DEBUG definition.
1993-07-07 05:50:35 +00:00
deraadt d670635e8b ok, 5 second command timeouts.. 1993-07-07 01:05:42 +00:00
deraadt 86999439b2 number of changes:
1. controller reset code moved into one function, called from more places now.
2. more places now do timeouts. TIPCAT code turned on.
3. blew away the unused WDOPENLOCK test code.
4. delay is now done using WDCNDELAY repetitions of DELAY(25). Up to 2.5 second
   pause accepted from controller (some controllers have some commands that are
   actually this slow)
5. some of the old timeout code was really whacked.
1993-07-06 00:42:43 +00:00
deraadt 2cb34d6d65 added a missing {/} pair that barsoom seems to have taken out, but
which the standard 386bsd 0.1 driver did have. This is for a piece of
code in the bad block handling. found/fixed by hpeyerl.
1993-07-05 04:44:48 +00:00
deraadt 3322c7b691 all timeout code now calls DELAY() so the timeout delays are the same
length on all processors. Where possible, the controller is reset if it
times out.
1993-07-05 03:20:57 +00:00
deraadt ed61b76822 increased the timeout inside wdcommand(). Some controllers impliment some
commands very slowly.
1993-07-05 00:08:27 +00:00
cgd d1ed63195d fix the divide-by-zero problem w/old disks. this patch is ws's "fault." 1993-06-18 20:45:35 +00:00
deraadt 2adecf84f6 1. It is now possible to build a kernel that does not have a pc0 device driver.
2. "press any key to reboot" reads the key from the console.
3. wddump() still needs a non-blocking getc() routine (or flush)
1993-05-28 09:10:52 +00:00
cgd 30177b538f add rcsids to everything and clean up headers 1993-05-22 07:56:12 +00:00
deraadt e34f239662 First cut at cpu independent disklabels.
There will be niggly little details no doubt..
1993-05-20 22:48:23 +00:00
deraadt 545cc18754 This patch allows the wd device driver to tell how big the disks are on
WD1007-derived controllers. In this example, wdc0 is a WD1007-clone,
and wdc1 is a WD1003-clone. WD1007 controllers are generally ESDI
and IDE controllers.
wdc0 at 0x1f0-0x1f7 irq 14 on isa
wd0 at wdc0 targ 0: 322MB 1224 cyl, 15 head, 36 sec <disktype>
wdc1 at 0x170-0x17f irq 7 on isa
wd2 at wdc1 targ 0: (unknown size) <disktype>

deraadt 5ae997897e i thought i deleted this line before! 1993-05-09 04:25:48 +00:00
deraadt a0bcb17e60 support for making dev->id_alive be set, this is for iostat to
find disk devices. wee bit of a kludge. sub-device attach()
routines must now return 1 for successful attach(), 0 otherwise.
Other bsd's do this too..
1993-05-04 08:27:29 +00:00
deraadt e2a9eb19a4 slight code quality improvement. not related to the bug with very
old controllers or disks! :-)
1993-04-18 10:03:20 +00:00
deraadt fbecd3e987 Once more: some changes to the ioconf.c structure. It will now handle
devices hanging off controllers, any kind of controller.
A device on isa0 is called at probe(self), then attach(self)
A controller on isa0 is called at probe(self), then all it's children with
    defined unit numbers are initialized by calling attach(subdev); next all
    subdevices with unit ? are initialized by calling attach(sundev).
Almost all device entry points is now like the vax/sun model (intr being
the weird one)
1993-04-15 07:52:08 +00:00
deraadt bf6814fb30 wd driver would fail on calling wdgetctlr() for older drives and
controllers. New behaviour is that if the standard method fails, try
to recalibrate the drive. Success means the drive exists.  patch by
hpeyerl@novatel.cuc.ab.ca (who owns several of these historical
artifacts)
1993-04-15 06:39:00 +00:00
deraadt f262b564a2 new scsi subsystem.
changes also in config/mkioconf.c & sys/scsi/*
1993-04-12 08:17:23 +00:00
cgd c2176edbac have probe return size of io space on successful return, rather
than simply 1.
1993-04-09 16:25:07 +00:00
deraadt b9bd4b25de dmesg output at boottime now tries to print out information as
soon as it is available. The output looks much more like Sunos.
1993-04-08 08:26:46 +00:00
deraadt a2b4863160 ripped out a message 1993-04-06 12:09:55 +00:00
deraadt 9b67a6d7ad Mod-barsoom wd additions. config program + kernel config files changed too.
fd support had to change slightly too.
