827d45ab08 Ack!
sometime around 1.51, the check for minphys dissappeared out of
transfers for disks..
we weren't hecking that the adapter could handle a transfer of
the size we were requesting..
Peter!?

this explains the rash of failures I've seen reported recently
with "too many DMA segments" on raw devices

(added one for st as well)

b629f8ebbe Some bug fixes for the worm driver:
o  don't use polled mode after the device probe phase
o  don't biodone() a NULL buffer pointer
o  increase the timeout for scsi_read_capacity(); WORMs are slooow
o  make WORMMs known to scsiconf at all

This brings the driver in a state where it at least doesn't
immediately panic, nor hangs the controller any more.  Unfortunately,
at least the YAMAHA CDR100 i've been testing with answered my write
attempts with an "Incorrect command sequence" response.  Perhaps other
CD burners might work however.

07b1c6b3c9 Remove hard coded assumption that SCSI busses have 7 targets.
This change forces the controller drivers to allocate a scsibus_data struct
via a call to scsi_alloc_bus(), fill in the adapter_link field, and optionally
modify any other fields of the struct.  Scsi_alloc_bus() initializes all fields
to the default, so the changes in most drivers are very minimal.  For drivers
that support Wide controllers, the maxtarg field will have to be updated to
allow probing of all targets (for an example, look at the aic7xxx driver).

Scsi_attachdevs() now takes a scsibus_data* as its argument instead of an
sc_link*.  This allows us to expand the role of the scsibus_data struct for
other bus level configuration setings (max number of transactions, current
transaction opennings, etc for better tagged queuing support).

73145c38cc Change memcmp() to bcmp(). memcmp() isn't declared or implemented
for the kernel, but gcc provides an inline version of it if the
kernel is compiled with -O.

The inline memcmp() is OK for small compares and is better than
the dumb kernel bcmp() in all cases, but it has been hiding the
library memcmp() which is 4 times faster for large compares.

31acd246c0 Allow the specification of the controller bus when wiring down scsi buses.
This is performed by using a line similar to:

ffc2aaf2d8 Do not set SCSI_NOSLEEP on every tape command (the exception being during
probes).  Apart from there being no reason to set SCSI_NOSLEEP on every
tape command, this prevents controller drivers from sleeping when resources
are fully utilized causing unecessary "Oops not queued" errors.  This is
only noticed for controllers that can run out of resources like the
27/2842 adaptec controllers.  Before this fix, it is almost impossible to
perform extended tape operations if more than one scsi disk is on the
bus with the tape drive with these controllers.  This does not address a
similar problem that could occur if devices are probed while other targets
are active since SCSI_NOSLEEP will still be set in that case.

a1c6084710 Support disk slices. This involves mainly replacing inline code with

Close the device in sdsize().  Media removal could not have worked right
when unused swap devices were held open.  There may now be a problem
with used swap devices not being held open.

Fix ancient operator precedence bug in sddump().  It may have been
possible to attempt dumping to unloaded media.

Remove NetBSD ifdefs.  We're too different now, and the NetBSD driver was
already too different for them to be relevant.

Remove support for soft write protection.  There are no ioctls to set it,
and this driver never set it either.  It was used in the wd driver to
disable writing to unlabelled disk, but we want to support writing to
foreign partitions on unlabeled disks.

Calculation of 'cd->cmdscount' now as in 'sd.c' (required for ncr scsi).
CDOUTSTANDING defined as '1' (as the comment says), was '2' in fact ...
Debugger takes an (char*) argument, changed macro definition accordingly.

9aba88bf29 Rather than exclude bounce buffers support with NOBOUNCE, include it
with BOUNCE_BUFFERS. This is more intuitive, and is better for future
multiplatform support. Added BOUNCE_BUFFERS option to the GENERIC and
LINT kernel config files.

in your kernel config now).
2) Added ps ddb function from 1.1.5. Cleaned it up a bit and moved into its

3) Added \r handing in db_printf.
4) Added missing memory usage stats to statclock().
5) Added dummy function to pseudo_set so it will be emitted if there

f540b1065a Change all #includes to follow the current Berkeley style. Some of these
``changes'' are actually not changes at all, but CVS sometimes has trouble
telling the difference.

This also includes support for second-directory compiles.  This is not
quite complete yet, as `config' doesn't yet do the right thing.  You can
still make it work trivially, however, by doing the following:

rm /sys/compile
mkdir /usr/obj/sys/compile
ln -s M-. /sys/compile
cd /sys/i386/conf
config MYKERNEL
cd ../../compile/MYKERNEL
ln -s /sys @

	causing the vnode pager error 5 messages when paging from
	NFS. (pmap.c)
2) put back interrupt protection in idle_loop. Bruce didn't think
	it was necessary, John insists that it is (and I agree). (swtch.s)
3) various improvements to the clustering code (vm_machdep.c). It's
	now enabled/used by default.
4) bad disk blocks are now handled properly when doing clustered IOs.

NB: -Wtraditional will henceforth be forgotten.  This editing pass was
primarily intended to detect any constructions where the old code might
have been relying on traditional C semantics or syntax.  These were all
fixed, and the result of fixing some of them means that -Wall is now a

57594c8752 Patch from Julian Elischer:
Here is the fix for the 'hanging' bug.

This bug happenned whenever two operations were already underway on the
disk and a third (non-IO) command was requested..
in this case the process submitting the NON-IO command was requested to wait,
and a flag set so that on completion of the IO commands, the Non-io command
was given priority over any pending IO commands. (the queue is not
allowed to drain while there are pending "special" ops).

The flag that indicated this was not being reset, so further IO commands
were prohibited from that moment on.

Date: Mon, 11 Oct 1993 03:02:39 -40962758 (WST)

Some tapes won't do anything until you tell them to load.
Other tapes think that being asked to load is a great excuse to
make the next command return a "unit attention" (media changed) error.
Since we need to do the load, throw in a dummy instruction to cop the
error.

specifically for DEC DAT drives.

1/ fix bug where cd0a was unusable because it was compared against
the number of 2k blocks not the number of 512byte blocks.. gave
an error for all reads past 1/4 way through the disk (cd0d was ok).

2/ fix open code so that it now notices if a disk has been changed
and updates the disklabel.

3/ use the new error handling code from st.c

4/ start adding stuff to get ready for using cd_scsi_cmd from
cd_start (like is done in st and sd)

5/ more general cleanups including making dmesg report
sector size of disk.. (believe it or not SUN drives use 512 byte)

f03cb6c766 The scsi cd.c driver is now fully dynamic. You can change the lines
in your config file from:
device          cd0
device          cd1
...
device          cdn
to either
device          cd0
or
psuedo-device   cd0

The driver now dynamically allocates all per unit dependent structs, so it
will never run out of units (okay, so now we need 32 bit device major/minor
numbers!).  It will allocate unit numbers as it needs them.
