12ab8490af Set the return value (outb'd to the sequencer) for non zero status
interrupts to zero to start with.  This is the value we return in
most cases.  The sense code then outbs the apropriate value to cause
sense retrieval.  The return value was uninitialized before this
change (something that was an okay thing with the old sequencer code,
but not with the semantics of the new).

This problem caused us to always retrieve sense upon recieving a non
zero status byte.  This is exactly what was happening for the "target
busy" status returned by exabyte tape drives when they rewind or
power on with a tape installed.  The request sense proved fatal.
This should fix the tape problems.

a52deb6d1e Additions to support the WAITING_SCB list that the sequencer maintains.
It is the kernel driver's responsibility to do the list manipulation whenever
a selection timeout or a request sense occurs.

Print out the interrupt type that the device has been set to.  It seems that
one of the Asus motherboards botches this and David thought a diagnostic would
be nice.

Fix a bug in my diagnostic code that David found.

6ec8ee4578 Fix benign type mismatches int console functions. dev_t was assumed
to be `int' or smaller and some functions returned `int' instead
of `void'.  The first bug was detected when console functions were
defined in a place central enough for type checking to actually
work and the second bug was introduced when the interface was
changed to match what the console functions in other drivers actually
return.

929abd248d I noticed that some new -W options had been turned on the kernel compile since
I made the changes I sent you before.  In the interests of cleanliness, I made
modifications to /sys/i386/isa/tw.c to kill the warnings and make it compile
clean.  While I was at it, I also made a bunch of internal functions static.

c6baec432a Don't arbitrarily set SCSI_NOSLEEP. It is now handled correctly by the
higher level scsi code.

Spls should never be conditionalized, so don't do so here.

Restructure the get_scb routine so that we can't get into an infinite
loop if the ccbs are exhausted and we are are called with SCSI_NOSLEEP set.

Other driver maintainer's that based their scb allocation routines on Julian's
code should look at these changes and implement them for their driver.

The aic7xxx driver inspired these changes because early revs of the
aic7770 chips have so few SCBs that you can actually run out.  If you
have a rev C or aic7770 (as is reported by the driver probe) and had more
than 2 drives, you could get into an infinite loop when using up all of
the SCBs.  Since the driver will only allow two SCBs per device and I
only had two devices, I never saw this problem on my Rev C card.

Bzero only 19 bytes of the scb instead of 2k (ack!).  This was a hold
over from when a struct SCB only contained the information downloaded
to the board, but we now store kernel driver data in there as well.  This
greatly lowers the overhead for small transactions (I get ~1MB/sec for
dds with a 512 byte block size).

8da0f3b87a Make some functions static like they always should have been.
Change the interfaces of these functions to save space.  The code
that takes the least amount of space is often the opposite to what
you might expect.  E.g., it helps to waste a few bytes passing
pointers so that the compiler can't see that certain addresses
are identical (gcc likes to waste space by reloading fat constants
even when the constant is already in a register).

Rewrite getbootdev() to save 80 bytes of space and to make it less
ugly.  32 bytes were saved simply by omitting the continue statements
in the pseudo-switch.

Bruce Evans
a9ef92e638 Never pass char or short args to functions. This saves 64 bytes of
recently introduced bloat in just 2 calls to biosread(), although
very little in calls to putc() and serial_putc().  Gcc produces
amazingly bad code for unnecessary conversions.  E.g., if it has
`int x' in register %edx and wants to pass a char, then it could
simply push %edx and access only one byte in the callee.  Instead,
it sometimes unnecessarily spills %edx; it always sign extends
%edx and pushes the result.

Remove useless `extern' in function prototypes.

Remove unused declaration of `end'.

Declare pbzero() and pcpy() like the library bzero and bcopy().

Declare printf() properly.

9c6e0c69be . Make Poul's boot2 overflow warning less noisy in case the blocks
do fit, and beeping in case of an overflow.

.  Drop a comment about the ``FORCE_COMCONSOLE'' option into
   README.serial.

.  Increase the name buffer for the root directory from 100 bytes
   to 8 KB;  this is in no way ideal, but (IMHO) the best that can
   be done by now.  People did encounter problems with their root
   dir name listing overflowing the allocated buffer space.  Once
   we've got the three-stage boot, we should implement some basic
   malloc().  Swap space is already getting tight now, perhaps the
   swap should go into another 64 KB segment instead.

.  Make the keyboard probe less paranoid.  It should not give up in
   case of a keyboard that's continuously demanding RESEND's.  Even
   though the keyboard reset apparently has not been reported to be
   complete, it's at the very least proven that there IS something
   like a keyboard available.

   This solves problems with the ``Gateway-2000 AllKey programmable''
   (sp?) keyboard, that experienced a total hang with the previous
   probe.

   Thanks goes to Scott Blachowicz <scott@statsci.com> for his
   extensive testing of my various interim (debugging) bootblocks
   to get this working.
