6254670e83 Re-port over all of Atsushi Murai's 32bit support and various and sundry
improvements from 1.1.5.1.  I tried to compile a kernel without BOUNCE_BUFFERS
with the previous version for my Bt946c and it puked and died.  Bringing
these enhancements back in allows the faster controllers to DTRT while
still not messing up the older ISA/broken VLB controllers, since
bounce-buffering is still the default.  In theory, anyway.  Bt445S and Bt545S
folks should start testing this ASAP!  (actually, Bt445C and Bt545C folks
even more so!).

3f31c649d1 Redo Kernel NTP PLL support, kernel side.
This code is mostly taken from the 1.1 port (which was in turn taken from
Dave Mills's kern.tar.Z example).  A few significant differences:

1) ntp_gettime() is now a MIB variable rather than a system call.  A few
fiddles are done in libc to make it behave the same.

2) mono_time does not participate in the PLL adjustments.

3) A new interface has been defined (in <machine/clock.h>) for doing
possibly machine-dependent things around the time of the clock update.
This is used in Pentium kernels to disable interrupts, set `time', and
reset the CPU cycle counter as quickly as possible to avoid jitter in
microtime().  Measurements show an apparent resolution of a bit more than
8.14usec, which is reasonable given system-call overhead.

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()

5b7ffe398f Digicom Systems Inc, makes "softmodems". What this means is simply that
you download the microcode to the DSP everytime you power on your system.
They provide a dos-program to do so, but no other support.  This commit adds
code to the sio-driver, which implement an ioctl, which will down-load the
micro-code.

To get this functionality, you must define DSI_SOFT_MODEM.

The program to actually employ the ioctl is not included, but the entire
source looks like this:

        #include <sys/ioctl.h>
        #include <stdio.h>

        main()
        {
                unsigned char buffer[100000];
                int i;

                read(0,buffer,100000);
                if((i = ioctl(1,TIOCDSIMICROCODE,buffer)) < 0)
                    perror("ioctl");
                return i;
        }

And you use it like this:
	smload < data144b.dsi > /dev/ttyid3

You need to copy the *.DSI files from the dos-media provide with your modem.
You can see what is downloaded by issuing the ATI3 command to the modem.
DSI's scheme for what code you can run on your modem isn't violated by this.

30902edcfb ProAudioSpectrum 16 {Zilog|Ncr} 5380 based SCSI-driver.
This puppy is in good shape now.

It is a fully blown SCSI-driver, but it isn't a high performance one.  It is
implemented entirely with polled I/O, and is intended to drive CD-ROM's, not
disks and tapes.  It will run disks and tapes if asked to, but it isn't a
very good idea to do so.  Transfer-rates max out at 600-700 kbyte/sec.

There is one problem: when write-requests get over 8192 bytes, the pseudo-DMA
stalls.  This is only a problem if you dd(1) to a raw-device of some kind,
for mounting a disk it is ok.  I have circumvented this by disabling the
pseudo-DMA in those cases.

It's very unlikely that I will spend more time on improving the performance
of this driver, it can do what I want it to now: install from a CD-ROM, and I
don't see any benefit in actually adding interrupts to the driver, considering
that performance never will be better than 700 kbyte/sec anyway.

You can install it under 1.1.5 too, by adding the lines to files.i386, your
config-file and copying pas.c and ic/ncr_5380.h over.

I will fix any bugs I can get a handle on.

3e0a35fee4 Updated to final 1.1.5 version (revision 1.56).
Merged changes from 2.0 version (revisions 1.46-1.50) by hand.

Finished conversion to clists: removed flush of tty output buffer
in comflush() (most writes were truncated to 256 bytes) and restored
bypass of ttyinput() in siopoll().

Finished conversion to 2.0 types - more void *'s, less caddr_t's,
less casts, no Dev_t's.

Only these things are seriously broken now compared with 1.1.5:
waiting for output complete is impossible so ttywait() can deadlock;
sioclose() isn't called enough so sioopen() sometimes returns EBUSY
unnecessarily; input flow control is not implemented.

f0b544e99e Restore the intr_* array variables that were removed in the previous
revision.  They caused redundant redeclaration warnings because I
forgot to declare them as extern and gcc-2.6.0 treats "extern int x[];"
slightly different from "int x[];" (this is probably a bug).  The new
versions will cause RR warnings from gcc-2.4.5 because it does not
understand that the second declaration in "extern int x[]; int x[1];"
is not redundant.  The variables don't actually need to be declared
in a header file because they are used in only one C source file and
one assembler source file, but I want all public variables and
comments about them to be findable by grepping *.h.

e9d1679134 Added my ProAudioSpectum SCSI driver for cards with the 5380 SCSI-chip.
This is the slowest and most stupid of our SCSI-drivers, but it is there
and it works.  It has been tested with CD-ROM and disk.
It uses no interrupts, no DMA, just polled I/0.
Transfer-rate is <= 100Kbyte/sec.
If you set the jumpers on the board, you can change the unit-number and
you will be able to have four of these co-exist in one computer, why one
would do that is somewhat unclear though.
If I ever get my hand on the docs for this, I will improve it of course,
but for now we can install and access those CD-ROMs.

8912c0ed61 Bruce Evans' dynamic interrupt support.
/usr/src/sys/i386/isa/clock.c:
	o Garrett's statclock changes.
	o Wire xxxintr, not Vclk.
	o Wire using register_intr(), not setidt().

/usr/src/sys/i386/isa/icu.s:
	o Garrett's statclock changes.
	o Removed unused variable high_imask.
	o Fake int 8 for rtc as well as int 0 for clk.  Required for kernel
	  profiling with statclock, harmless otherwise.

/usr/src/sys/i386/isa/isa.c:
	o Allow isdp->id_irq and other things in *isdp to be changed by
	  probes.  Changing interrupts later requires direct calls to
	  register_intr() and unregister_intr() and more care.
	  ALLOW_CONFLICT_* is brought over from 1.1.5, except
	  ALLOW_CONFLICT_IRQ is not supported.  IRQ conflict checking is
	  delayed until after probing so that drivers can change the IRQ
	  to a free one; real conflicts require more cooperation between
	  drivers to handle.
	o Too many details to list.
	o This file requires splitting and a lot more work.

/usr/src/sys/i386/isa/isa_device.h:
	o Declare more things more completely.

/usr/src/sys/i386/isa/sio.c:
	o Prepare to register interrupt handlers as fast.

/usr/src/sys/i386/isa/vector.s:
	o Generate entry code for 16 fast interrupt handlers and 16 normal
	  interrupt handlers.  Changed some constants to variables:
	  # $unit is now intr_unit[intr].  Type is int.  Someday it should
	    be a cookie suitable for the handler (e.g., a struct com_s for
	    sio).
	  # $handler is now intr_handler[intr].
	  # intrcnt_actv[id_num] is now *intr_countp[intr].  The indirection
	    is required to get a contiguous range of counters for vmstat
	    and so that the drivers depend more in the driver than on the
	    interrupt number (drivers could take turns using an interrupt
	    and the counts would remain correct).  There is a separate
	    counter for each device and for each stray interrupt.  In
	    1.1.5, stray interrupt 7 clobbers the count for device 7 or
	    something worse if there is no device 7 :-(.
	  # mask is now intr_mask[intr] (was already indirect).
	 o Entry points are now _XintrI and _XfastintrI (I = intr = 0-15),
	   not _VdevU (U = unit).
	 o Removed BUILD_VECTORS stuff.  There's a trace of it left for
	   the string table for vmstat but config now generates the
	   string in one piece because nothing more is required.
	 o Removed old handling of stray interrupts and older comments
	   about it.

Added my if_lp TCP/IP driver to lpt.c.
I have (surprise) not been able to test it on a 2.0 machine yet.  Connect the
machines with a parallel "lap-link" cable, and get rates from 35 kbyte/sec
up to 75 kbyte/sec.  (when ftp'ing foo: dev/zero -> bar:/dev/null).

The same lpt.c file should compile under 1.1.5.1 without problems.

I think we should promote this feature when we dump 2.0 on the expectant
public, because it provides a cheap and efficient way to move data to and
from notebooks &c.  It is not a replacement for ethernet, but a cheap
substitute sometimes.

	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.
	(wd.c, vm_machdep.c)
5) bogus bad block handling fixed in wd.c.
6) algorithm improvements to the pageout/pagescan daemons. It's amazing
	how well 4MB machines work now.

a4392a014c Fixed brokeness in the support of the 83C790/Elite Ultra (now that I
finally have the f**king documentation!):

1) Changed all the numeric register offsets to symbolic ones (it should
	have been this way originally).
2) If 16 bit, disable the shared memory when not using it. Apparantly
	switching between 8/16bit mode makes the Ultra unhappy unless
	this is done (i.e. it trashes the bus).

fd59ff8180 CHANGES from Bruce:
---
This list of changes is in approximately chronological order (oldest first).

	o Many cosmetic changes - renamed comintr1 -> siointr1, moved
	  things around and fixed whitespace.
	o Reduced SLIP latency (FRAME_END hack) from 20-30 ms to 16 ms
	  at 115200 bps (you won't notice the average 10 ms improvement
	  on slow lines).  ppp seems to use only counted transfers so
	  there's no similar hack available.  It's too hard for the
	  driver to know the count.
	o Temporary #ifdefs for new and old interrupt handling
	  (OLD_INTERRUPT_HANDLING decided by setsofttty() not being
	  externally defined.
	o Don't test for the IIR_NOPEND bit being set - test for the
	  non-fifo part of the iir equalling it like the docs say to.
	  States with other IIR_NOPEND set in combination with the
	  other iir bits are undefined.  The docs may be stupid - the
	  old test would not have broken when the fifo bits were
	  introduced.
	o Noted more problems with DTR wait.
	o Rewrote console stuff.  Still some initialization and state
	  preservation problems.  Same for kgdb stuff.  The driver
	  doesn't do anything about the console close bug.  It needs
	  to be fixed entirely in i386/cons.c.  I like chmr's version
	  where the the console driver revectors the device open and
	  close routines.
	o Temporary (?) #ifdefs for references to tty buffers.
	o Noted further things to do in (2 comments about 3 places) for
	  phk's change to not touch RTS unless it is being used for flow
	  control.
	o Temporary #ifdefs for timestamp handling.  It needs fixing.
	  The microtime() call breaks the first rule of writing fast
	  interrupt handlers: NO calls to functions that might do slow
	  and bad things.  microtime() enables interrupts.  This turns
	  out to be only moderately harmful.  Also, I want the timestamp
	  copy outside of the normal interrupt handler.
	o Don't init com->tp early for the !DONT_MALLOC_TTYS case -
	  both sides are NULL.
	o Worry about com->tp == NULL in siopoll.  I don't see how you
	  survived the (incc <= 0 || !(tp->state & TS_ISOPEN)) test.
	  Perhaps early sttys or comcontrols set up the tp's for _all_
	  the ports before this code is reached.

d230622648 New interrupt code from Bruce Evans. In additional to Bruce's attached
list of changes, I've made the following additional changes:

1) i386/include/ipl.h renamed to spl.h as the name conflicts with the
   file of the same name in i386/isa/ipl.h.
2) changed all use of *mask (i.e. netmask, biomask, ttymask, etc) to
   *_imask (net_imask, etc).
3) changed vestige of splnet use in if_is to splimp.
4) got rid of "impmask" completely (Bruce had gotten rid of netmask),
   and are now using net_imask instead.
5) dozens of minor cruft to glue in Bruce's changes.

   These require changes I made to config(8) as well, and thus it must
be rebuilt.

-DG

from Bruce Evans:

sio:
	o No diff is supplied.  Remove the define of setsofttty().  I hope
	  that is enough.

*.s:
	o i386/isa/debug.h no longer exists.  The event counters became too
	  much trouble to maintain.  All function call entry and exception
	  entry counters can be recovered by using profiling kernel (the new
	  profiling supports all entry points; however, it is too slow to
	  leave enabled all the time; it also).  Only BDBTRAP() from debug.h
	  is now used.  That is moved to exception.s.  It might be worth
	  preserving SHOW_BITS() and calling it from _mcount() (if enabled).
	o T_ASTFLT is now only set just before calling trap().
	o All exception handlers set SWI_AST_MASK in cpl as soon as possible
	  after entry and arrange for _doreti to restore it atomically with
	  exiting.  It is not possible to set it atomically with entering
	  the kernel, so it must be checked against the user mode bits in
	  the trap frame before committing to using it.  There is no place
	  to store the old value of cpl for syscalls or traps, so there are
	  some complications restoring it.

Profiling stuff (mostly in *.s):
	o Changes to kern/subr_mcount.c, gcc and gprof are not supplied yet.
	o All interesting labels `foo' are renamed `_foo' and all
	  uninteresting labels `_bar' are renamed `bar'.  A small change
	  to gprof allows ignoring labels not starting with underscores.
	o MCOUNT_LABEL() is to provide names for counters for times spent
	  in exception handlers.
	o FAKE_MCOUNT() is a version of MCOUNT() suitable for exception
	  handlers.  Its arg is the pc where the exception occurred.  The
	  new mcount() pretends that this was a call from that pc to a
	  suitable MCOUNT_LABEL().
	o MEXITCOUNT is to turn off any timer started by MCOUNT().

/usr/src/sys/i386/i386/exception.s:
	o The non-BDB BPTTRAP() macros were doing a sti even when interrupts
	  were disabled when the trap occurred.  The sti (fixed) sti is
	  actually a no-op unless you have my changes to machdep.c that make
	  the debugger trap gates interrupt gates, but fixing that would
	  make the ifdefs messier.  ddb seems to be unharmed by both
	  interrupts always disabled and always enabled (I had the branch in
	  the fix back to front for some time :-().
	o There is no known pushal bug.
	o tf_err can be left as garbage for syscalls.

/usr/src/sys/i386/i386/locore.s:
	o Fix and update BDE_DEBUGGER support.
	o ENTRY(btext) before initialization was dangerous.
	o Warm boot shot was longer than intended.

/usr/src/sys/i386/i386/machdep.c:
	o DON'T APPLY ALL OF THIS DIFF.  It's what I'm using, but may require
	  other changes.
	  Use the following:
		o Remove aston() and setsoftclock().
	  Maybe use the following:
		o No netisr.h.
		o Spelling fix.
		o Delay to read the Rebooting message.
		o Fix for vm system unmapping a reduced area of memory
		  after bounds_check_with_label() reduces the size of
		  a physical i/o for a partition boundary.  A similar
		  fix is required in kern_physio.c.
		o Correct use of __CONCAT.  It never worked here for non-
		  ANSI cpp's.  Is it time to drop support for non-ANSI?
		o gdt_segs init.  0xffffffffUL is bogus because ssd_limit
		  is not 32 bits.  The replacement may have the same
		  value :-), but is more natural.
		o physmem was one page too low.  Confusing variable names.
	  Don't use the following:
		o Better numbers of buffers.  Each 8K page requires up to
		  16 buffer headers.  On my system, this results in 5576
		  buffers containing [up to] 2854912 bytes of memory.
		  The usual allocation of about 384 buffers only holds
		  192K of disk if you use it on an fs with a block size
		  of 512.
		o gdt changes for bdb.
		o *TGT -> *IDT changes for bdb.
		o #ifdefed changes for bdb.

/usr/src/sys/i386/i386/microtime.s:
	o Use the correct asm macros.  I think asm.h was copied from Mach
	  just for microtime and isn't used now.  It certainly doesn't
	  belong in <sys>.  Various macros are also duplicated in
	  sys/i386/boot.h and libc/i386/*.h.
	o Don't switch to and from the IRR; it is guaranteed to be selected
	  (default after ICU init and explicitly selected in isa.c too, and
	  never changed until the old microtime clobbered it).

/usr/src/sys/i386/i386/support.s:
	o Non-essential changes (none related to spls or profiling).
	o Removed slow loads of %gs again.  The LDT support may require
	  not relying on %gs, but loading it is not the way to fix it!
	  Some places (copyin ...) forgot to load it.  Loading it clobbers
	  the user %gs.  trap() still loads it after certain types of
	  faults so that fuword() etc can rely on it without loading it
	  explicitly.  Exception handlers don't restore it.  If we want
	  to preserve the user %gs, then the fastest method is to not
	  touch it except for context switches.  Comparing with
	  VM_MAXUSER_ADDRESS and branching takes only 2 or 4 cycles on
	  a 486, while loading %gs takes 9 cycles and using it takes
	  another.
	o Fixed a signed branch to unsigned.

/usr/src/sys/i386/i386/swtch.s:
	o Move spl0() outside of idle loop.
	o Remove cli/sti from idle loop.  sw1 does a cli, and in the
	  unlikely event of an interrupt occurring and whichqs becoming
	  zero, sw1 will just jump back to _idle.
	o There's no spl0() function in asm any more, so use splz().
	o swtch() doesn't need to be superaligned, at least with the
	  new mcounting.
	o Fixed a signed branch to unsigned.
	o Removed astoff().

/usr/src/sys/i386/i386/trap.c:
	o The decentralized extern decls were inconsistent, of course.
	o Fixed typo MATH_EMULTATE in comments. */
	o Removed unused variables.
	o Old netmask is now impmask; print it instead.  Perhaps we
	  should print some of the new masks.
	o BTW, trap() should not print anything for normal debugger
	  traps.

/usr/src/sys/i386/include/asmacros.h:
	o DON'T APPLY ALL OF THIS DIFF.  Just use some of the null macros
	  as necessary.

/usr/src/sys/i386/include/cpu.h:
	o CLKF_BASEPRI() changes since cpl == SWI_AST_MASK is now normal
	  while the kernel is running.
	o Don't use var++ to set boolean variables.  It fails after a mere
	  4G times :-) and is slower than storing a constant on [3-4]86s.

/usr/src/sys/i386/include/cpufunc.h:
	o DON'T APPLY ALL OF THIS DIFF.  You need mainly the include of
	  <machine/ipl.h>.  Unfortunately, <machine/ipl.h> is needed by
	  almost everything for the inlines.

/usr/src/sys/i386/include/ipl.h:
	o New file.  Defines spl inlines and SWI macros and declares most
	  variables related to hard and soft interrupt masks.

/usr/src/sys/i386/isa/icu.h:
	o Moved definitions to <machine/ipl.h>

/usr/src/sys/i386/isa/icu.s:
	o Software interrupts (SWIs) and delayed hardware interrupts (HWIs)
	  are now handled uniformally, and dispatching them from splx() is
	  more like dispatching them from _doreti.  The dispatcher is
	  essentially *(handler[ffs(ipending & ~cpl)]().
	o More care (not quite enough) is taken to avoid unbounded nesting
	  of interrupts.
	o The interface to softclock() is changed so that a trap frame is
	  not required.
	o Fast interrupt handlers are now handled more uniformally.
	  Configuration is still too early (new handlers would require
	  bits in <machine/ipl.h> and functions to vector.s).
	o splnnn() and splx() are no longer here; they are inline functions
	  (could be macros for other compilers).  splz() is the nontrivial
	  part of the old splx().

/usr/src/sys/i386/isa/ipl.h
	o New file.  Supposed to have only bus-dependent stuff.  Perhaps
	  the h/w masks should be declared here.

/usr/src/sys/i386/isa/isa.c:
	o DON'T APPLY ALL OF THIS DIFF.  You need only things involving
	  *mask and *MASK and comments about them.  netmask is now a pure
	  software mask.  It works like the softclock mask.

/usr/src/sys/i386/isa/vector.s:
	o Reorganize AUTO_EOI* macros.
	o Option FAST_INTR_HANDLER_USERS_ES for people who don't trust
	  fastintr handlers.
	o fastintr handlers need to metamorphose into ordinary interrupt
	  handlers if their SWI bit has become set.  Previously, sio had
	  unintended latency for handling output completions and input
	  of SLIP framing characters because this was not done.

/usr/src/sys/net/netisr.h:
	o The machine-dependent stuff is now imported from <machine/ipl.h>.

/usr/src/sys/sys/systm.h
	o DON'T APPLY ALL OF THIS DIFF.  You need mainly the different
	  splx() prototype.  The spl*() prototypes are duplicated as
	  inlines in <machine/ipl.h> but they need to be duplicated here
	  in case there are no inlines.  I sent systm.h and cpufunc.h
	  to Garrett.  We agree that spl0 should be replaced by splnone
	  and not the other way around like I've done.

/usr/src/sys/kern/kern_clock.c
	o splsoftclock() now lowers cpl so the direct call to softclock()
	  works as intended.
	o softclock() interface changed to avoid passing the whole frame
	  (some machines may need another change for profile_tick()).
	o profiling renamed _profiling to avoid ANSI namespace pollution.
	  (I had to improve the mcount() interface and may as well fix it.)
	  The GUPROF variant doesn't actually reference profiling here,
	  but the 'U' in GUPROF should mean to select the microtimer
	  mcount() and not change the interface.

18e494b593 Used definable status codes (some may be sharable, esp the door open codes, but
it still looks a little suspicious that so many of the status codes are missing
so I'm not going to adopt all of the existing ones yet.  Try to be more
descriptive in the use of hex constants.

068a409099 Beginning of change set for making more friendly laptop configurations.
Changes _only_ take effect if `options LAPTOP' is set.

Note:  This one is distinctly dodgy. When my IDE drive spins back up from sleep
mode, it generates this `extra interrupt' condition by spinning back up and
generating an intr, though without any particular action required.  This
message coming out every time is rather annoying, and thus disabled.
However, what I'm not at all sure of is whether or not all IDE drives will
behave in the same way, or if perhaps it needs to be done in a more complicated
fashion by detecting this more involved "I've spun up and am just saying hi"
condition.  This is a simple change and easy to back out/ammend if anybody has
any better ideas.

563ac84861 Added more status bytes for the mitsumi drive. This is only an ugly
hack in the moment for testing purposes and to get the drive going
again.
0x20 means empty drive.
0x30 means closed drive with CDROM inserted.
0x80 means drive pulled out, but door closed.
0xa0 means drive pulled out and door open.
Luckily none of these values are the same as that reported for Ethernet
cards ( 0 for WD8003E, 0x40 for WD8013EPC, 0x60 for NE2000).
The bad part is, the probe code gets the WD8003E so hosed, that it is
no longer usable after it. No problem with the WD8013EPC.

my previous fix too (using wdp_heads controller value) and check
0 heads case too.

Other fixes from Bruce:
2) Fix dk_timeout from 2 to about 4 seconds.
3) wdcontrol not retried on internal error.
4) wdwait return check changed ( "!=0" to "<0" into wdsetctlr,
"<0" to "!=0" into wdgetctlr).

79bdab6c87 Ttys structures are now allocated dynamically via ttymalloc/ttyfree.
This inetrface should be used from now on.
pseudo device pty xx still keeps its meaning: a maximum of
xx ptys is allowed.
A ringbuffer is now 2040 bytes long, per Garrett Wollman's request.
The changes are inspired by the way NetBSD did it (thanks for that!),
though I made it slihghtly different, including the interface so
at least 75% of the allocated space is deallocated when the tty is
closed.
Note further that it is easy to modify the ringbuffer length runtime.
This will have to wait untill some later date...

768e8947c6 From: bde@kralizec.zeta.org.au (Bruce Evans)
o merged and fixed timeout code from sos.
	o merged DOS partition support from sos.
	o fixed "extra" interrupts.
	o check if malloc retuns NULL :-(.
	o print drive size as in NetBSD
	o after an error, return the residual count, not 0.
	o give up early for > 16 heads.
	o cleaned up the old-drive detection in wdgetctlr().
	o rewrote wddump().  I'd been putting this off because
	  I'd had the dump disabled since 0.0 and had no idea
	  if even the standard version worked.  It didn't:
	  (0) syscons' sgetc() interface broke some keyboard
	  stuff.
	  (1) CADDR1 is mapped using pmap() and pmap got a NULL
	  pointer trap (at least when I got to wddump() using
	  call diediedie from ddb) because the pte for CADDR1
	  is only supposed to be hacked on directly (e.g. in
	  physcopyseg()).
	  (2) bad144 handling was not done.
	  (3) it was slooow (3600 sectors/minute) because my
	  controller doesn't cache writes.
	o miscellaneous other cleanups, e.g., removed scattered
	  patchkit/terry dates.
	o lots of reformatting.

To be done:
	o Merge/fix TIH/NetBSD bad144 code (doesn't belong in any
	  particular driver.  Why aren't we using i386/dkbad.c?).
	o Merge/fix Dyson/NetBSD clustering code (large parts
	  should be shared).
	o Fix/extend the partition in use bits.  Support extended
	  partitions.  This should be shared by all disk drivers.  Swap
	  to a DOS partition so that the swap space can be shared with
	  linux.
	o Don't use polling except for initialization.  Need to
	  reorganise the state machine.  Then "extra" interrupts
	  shouldn't happen (except maybe one for initialization).
	o Fix disklabel, boot and driver inconsistencies with
	  bad144 in standard versions.
	o Look at latest linux clustering methods.  Our disksort()
	  gets in the way of clustering.
	o cleaned up the ATA changes (needs more work.  I think
	  the ATA specs say that the only thing really wrong with
	  the original version of wx is that there was no test
	  for drive-ready before some commands.  400 nsec delay
	  suffices for almost everything and 400 nsec delay is
	  usually "free").

6df720041a 1) Set ipending back to 4, because (16 + 4) bit not in
netmask or impmask.

2) Fixes from Bruce:
	o Changed name of schedsoftcom() to setsofttty() to match
	  setsoftclock()
	o Bool_t isn't used.
	o tx_fifo_size is 1 for chips without fifos, 16 for 16550's, to
	  help to output more efficiently for 16550's (LSR_TXRDY means
	  that the fifo is empty, not that it has space for one char).
	o Changed name of softsio1() to siopoll() and merged compoll()
	  into siopoll().
	o The probe forgot to clear com_mcr after it failed.  This is
	  harmful for 4 single serial ports on 2 interrupts.  It makes
	  partial misconfigurations worse.
	o Don't bother initializing static variables that are 0 (bidir
	  stuff).
	o Only initialize t_oflag to TTYDEF_OFLAG if unit == COMCONSOLE,
	  not if COMCONSOLE is defined.
	o Don't call siointr() from comparam() if there is no output in
	  progress.  For the call from sioopen(), there's no output in
	  progress, and siointr() often saw silo overflows for stale
	  input because it was called before sioopen() discarded the
	  input.
	o Let ttselect() do the work for select(), so that the fixes for
	  ttselect() don't have to be duplicated in zillions of drivers.

3579d8917b Patch from dcjm@cs.ed.ac.uk (Dave Matthews)...
Yes, I know that IFADDR ioctl is supposed to be deprecated... Note
that the patch was modified by me to fit better into the driver. -DG

...

While porting CAP to 386bsd/pk0.2.4 and now to FreeBSD Release 1.0
I found a couple of bugs associated with the packet filter. Here
are the fixes.  I'm posting them here because they apply to
FreeBSD and 386bsd/pk0.2.4 and possibly to other *BSD.

The first occurs when using the packet filter to write raw
ethernet packets.  The header consisting of the sender and
destination addresses and the protocol is removed and later
added back on, but with the byte order of the protocol reversed.
The fix ensures that the byte order in the protocol field is
swapped when it is removed.

The second fix ensures that SIOCGIFADDR works for BPF as claimed
in the man pages, by adding it to the ed driver.  Similar fixes
will be needed for other ethernet drivers.

d6eb591433 Patch from Brian Smith (modified a little by me) to allow kernel config
file override to disable fifo on 16550s:

I bought a board with two 16550's, but one of those ports has a mouse
on it.  The sio driver always enables the fifo, which is a bad thing
for mice and X.  The mouse is jerky and hard to use.  The simple thing
is be to treat one of the ports as a non-fifo'ed UART, and I use the
flags option in my config file.

So, my config file has:
device      sio0    at isa? port "IO_COM1" tty irq 4 flags 0x2 vector siointr
device      sio1    at isa? port "IO_COM2" tty irq 3 vector siointr

	Don't force HUPCL for bidirectional case.
From bde:
	Use bit (1 << (16 + 4)) in schedsoftcom() to avoid clash with
	non-serial h/w on IRQ4.
	Allow FIFO_TRIGGER in config.
	Clear com->mcr_image when clearing mcr for init of 4port.  The

	Drain fifo more carefully.
	Don't hang up if debugging.
	Rearrange siointr() -> siointr1() for multiport case for speed,

	Use suser() to check perms.
	Provide missing splx() after failed perms checks.

4aba964ef1 New wd driver, based on Bruce Evans 'wx/altwd' driver which has passed
enough tests to be considered more stable than current driver.

Lots of work by Bruce, David G., and Guido have gone into this version, and
more is to come in the future.

Support for multiple controllers is in, but doesn't work correctly with
different controllers (IDE AND MFM), but multiple alike controllers appears
to work.

Most of the stray interrupts problems should be fixed, although you will
get a couple 'extra interrupts' when disklabeling and on startup.

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

8b4d35c5ee wt.c - version 1.3
from:
Sergey Ryzhkov, Serge Vakulenko
E-mail: <sir@kiae.su>, <vak@zebub.msk.su>

This is the streamer tape driver for 386bsd and FreeBSD, which
supports Wangtek and Archive compatible QIC-02/QIC-36 controllers.
It was developed as a replacement of the old Wangtek tape driver from CMU.

In comparison with the CMU driver, this version has the following enhancements:
1) Support for Archive SC402 and SC499 tape controllers added.
2) Support for up to three tape controllers on the same machine.
3) Support for BSD-style ioctls MTIOCGET, MTIOCTOP.
   Mt command now works adequately with this driver.
2) Asynchronous REWIND and FSF operations, close() will not wait
   until they finish.  The next open() will wait for it instead.
4) Use of WTQICMD ioctl is limited to ERASE and RETENS operations.
   This prevents the user from locking the tape driver by strange
   tape operations.
5) Tape density switching added.
6) The status of the process, blocked on the tape operation,
   is displayed at the WCHAN column of the `ps' command as:

	wtread    reading data from the tape
	wtwrite   writing data to the tape
	wtrfm     reading the tape marker
	wtwfm     writing the tape marker
	wtrew     rewinding the tape
	wterase   doing WTQICMD ERASE operation
	wtretens  doing WTQICMD RETENS operation
	wtorew    doing MTIOCTOP REW/OFFL operation
	wtorfm    doing MTIOCTOP FSF operation
	wtowfm    doing MTIOCTOP WEOF operation

7) It's possible to use the tape with "default density",
   useful for devices which don't support density switching
   or do automatic format determination.
8) Some controllers support only 1024 block length.
   Setting WT_BSIZE bit in device minor number turns on this mode.

Minor number structure:
	0bfffuuu
Fields:
	uuu   - Unit number. It's possible to install
		up to three tape controllers on the same machine,
		using DRQs 1..3.  Hence, unit number can lie
		in range 0..2.
	fff   - Tape format number:
		0 - /dev/rwt0  - default density (auto select)
		1 - /dev/rwt0a - QIC 11 (obsolete)
		2 - /dev/rwt0b - QIC 24 (60 megabytes)
		3 - /dev/rwt0c - QIC 120 (120 megabytes)
		4 - /dev/rwt0d - QIC 150 (150 megabytes)
		5 - /dev/rwt0e - QIC 300 (300 megabytes?)
		6 - /dev/rwt0f - QIC 600 (600 megabytes?)
	b     - Long block size flag.  With this bit set,
		the driver will perform all i/o operations
		with the controller using 1024-byte
		blocks, instead of 512 ones.
		Some controllers need it (CMS for example).
		If you Wangtek controller does not stream well,
		you can try to use /dev/rWt0 device instead
		of /dev/rwt0 (uncomment needed lines in /dev/MAKEDEV
		to create it).

Block interface (writing blocks less than 2048 bytes) is not functioning
pwoperly.  Use raw interface instead.

Thanks to all who helped to test it on the following hardware:

16111ced9f Reset fdc during probe.
From: <dec@lazarus.nrtc.northrop.com>
   Changes between EPSILON and RELEASE of FreeBSD have again caused
the kernel to not see my floppy disk drives.  I don't know what happened,
'cause I don't see any changes to fd.c, but here is an old fix that
I have applied to the probe routine which will solve the problem (at
least for me).  Since this is a rather brute-force solution - I understand
if you want to ignore it...

Subject: IDE-disk hangs - solution/patches NetBSD/FreeBSD
Summary: fixes for lost interrupts with IDE disks
Keywords: hanging-disk, IDE-disk, lost-interrupt


Due to "popular" demand I'm posting these patches to NetBSD/FreeBSD
instead of mailing them around the world :-)

As many have found out there is a problem when using IDE disks on
FreeBSD. Following is a patch that fixes the problem with lost intterrupts.
Both fixes is based on a patch posted here some month ago by
Stefan Behrens?? (sorry I've lost the original article). But anyway it
works (for me :-).
Basically it does a timeout on lost interrupts, starting the operation
again and logging and error message on the console.

It additionally makes the allready present while loop timeouts
independent of CPU speed, and adds minor numbers for easy access to
dos partitions.

3) replaced some hardcoded constants with cpp defines (such as
	PDESIZE and others)
4) aligned all comments to the same column to make them easier to
	read
5) moved macro definitions for ENTRY, ALIGN, NOP, etc. to
	/sys/i386/include/asmacros.h
6) added #ifdef BDE_DEBUGGER around all of Bruce's debugger code
7) added new global '_KERNend' to store last location+1 of kernel
8) cleaned up zeroing of bss so that only bss is zeroed
9) fix zeroing of page tables so that it really does zero them all
	- not just if they follow the bss.
10) rewrote page table initialization code so that 1) works correctly
	and 2) write protects the kernel text by default
11) properly initialize the kernel page directory, upages, p0stack PT,
	and page tables. The previous scheme was more than a bit
	screwy.
12) change allocation of virtual area of IO hole so that it is
	fixed at KERNBASE + 0xa0000. The previous scheme put it
	right after the kernel page tables and then later expected
	it to be at KERNBASE +0xa0000
13) change multiple bogus settings of user read/write of various
	areas of kernel VM - including the IO hole; we should never
	be accessing the IO hole in user mode through the kernel
	page tables
14) split kernel support routines such as bcopy, bzero, copyin,
	copyout, etc. into a seperate file 'support.s'
15) split swtch and related routines into a seperate 'swtch.s'
16) split routines related to traps, syscalls, and interrupts
	into a seperate file 'exception.s'
17) remove some unused global variables from locore that got
	inserted by Garrett when he pulled them out of some .h
	files.

i386/isa/icu.s:
1) clean up global variable declarations
2) move in declaration of astpending and netisr

i386/i386/pmap.c:
1) fix calculation of virtual_avail. It previously was calculated
	to be right in the middle of the kernel page tables - not
	a good place to start allocating kernel VM.
2) properly allocate kernel page dir/tables etc out of kernel map
	- previously only took out 2 pages.

i386/i386/machdep.c:
1) modify boot() to print a warning that the system will reboot in
	PANIC_REBOOT_WAIT_TIME amount of seconds, and let the user
	abort with a key on the console. The machine will wait for
	ever if a key is typed before the reboot. The default is
	15 seconds, but can be set to 0 to mean don't wait at all,
	-1 to mean wait forever, or any positive value to wait for
	that many seconds.
2) print "Rebooting..." just before doing it.

kern/subr_prf.c:
1) remove PANICWAIT as it is deprecated by the change to machdep.c

i386/i386/trap.c:
1) add table of trap type strings and use it to print a real trap/
	panic message rather than just a number. Lot's of work to
	be done here, but this is the first step. Symbolic traceback
	is in the TODO.

i386/i386/Makefile.i386:
1) add support in to build support.s, exception.s and swtch.s

...and various changes to various header files to make all of the
	above happen.

Has NOBODY used the isa_dmastart() routine for 16bit DMA?

I know I just hit the dma regs directly for the AHA1542,
and it appears that either everybody else does as well, or
they only use 8bit DMA (e.g. floppy)

byte of information, when the adaptec manual clearly states that 4
bytes are to be returned.  I added a printf that explains the error

5c644711a9 ALL:
Removed patch kit headers and rcsid strings, add $Id$.

isa.c:

Removed old #ifdef notyet isa_configure code, since it will never be
used, and I have done 90% of what it attempted to.

Add conflict checking code that searchs back through the devtab's looking
for any device that has already been found that may conflict with what
we are about to probe.  Checks are mode for I/O address, memory address,
IRQ, and DRQ.  This should stop the screwing up of any device that has
alread been found by other device probes.
Print out messages when we are not going to probe a device due to
a conflict so the user knows WHY something was not found.  For example:

aha0 not probed due to irq conflict with ahb0 at 11

Now print out a message when a device is not found so the user knows
that it was probed for, but could not be found.  For example:

ed1 not found at 0x320

For devices that have I/O address < 0x100 say that they are on the
motherboard, not on isa!  The 0x100 magic number is per ISA spec.  It
may seem funny that pc0 and sc0 report as being on the motherboard, but
this is due to the fact that the I/O address used is that of the keyboard
controller which IS on the motherboard.  We really need to split the
keyboard probe from the display probe.  It is completly legal to build
a pc with out one or the other, or even with out both!

npx.c:

Return -1 from the probe routine if we are using the Emulator so
that the i/o addresses are not printed, this is the same trick used
for 486's.

Do not print the ``Errors reported via Exception 16'', and
``Errors reported via IRQ 13'' messages any more, since these just lead
to more user confusion that anything.  It still prints the message
``Error reporting broken, using 387 emulator'' so that the person is
aware that there mother board is ill.

Okay, I tracked down the d*mn thing that is causing the memcpy to be
emmitted by gcc2.  In the following patch is a fix to eliminate the
one place that was causing gcc to do the memcpy in function ie_readframe
for the ie_recv_frame_desc rfd = *(ie->rframes[num]) structure copy.

I also fixed the code so that the NS (XNS) support would compile with
out error and removed the cruft #define ns_* stuff from the softc
structures (I did this a while back for all the other either drivers)

Removed the $Log$ and all of the old log stuff, that is all kept in
the cvs tree, no need to duplicate it in the file... I'll copy it
into my commit message so that it is all retained, except the
revision numbers are going to get screwed up.

It now compiles cleanly under my LINT kernel...

 * Attach routine now returns void.
 *
 * Revision 1.26  93/06/08  16:31:21  wollman
 * Deleted attempt to set watchdog timer, since we don't use it.
 *
 * Revision 1.25  93/04/16  22:15:31  wollman
 * Fixed infinite loop in iestart() which would cause the transmitter
 * to constantly step on the Ethernet, sending the same two packets over
 * and over again.  This crashes the router (really!) and makes other
 * network users very angry.
 *
 * Revision 1.24  93/04/14  23:57:47  wollman
 * Increased transmit buffer size from 1504 to 1512, just in case I don't
 * understand how the MTU is used.
 *
 * Revision 1.23  93/04/14  23:16:19  wollman
 * Fix iestart() so that it only tries to execute a command if one was
 * queued up (oops...).
 *
 * Revision 1.22  93/04/14  23:02:16  wollman
 * Unknown changes.
 *
 * Revision 1.21  93/04/12  18:29:33  wollman
 * Added multiple transmit commands.  Note that they are always queued in
 * pairs (there are only two to begin with), and the I flag is only set
 * on the second one.  This should decrease interrupt activity somewhat.
 *
 * Revision 1.20  93/04/12  15:36:05  wollman
 * Changed setup of config block to take into account difference between
 * StarLAN (10BASE-T) and Ethernet: StarLAN is Manchester, Ethernet is NRZ.
 *
 * Revision 1.19  93/03/23  18:58:44  wollman
 * Raised count of receive buffers from 32 to 48 and included analysis of
 * memory usage in a comment near that definition.
 *
 * Revision 1.18  93/03/18  03:59:53  wollman
 * Last try to get large TCP windows to work...
 *
 * Revision 1.17  93/03/18  03:54:10  wollman
 * Added RNR processing as a part of receive interrupts.  Hopefully this
 * will make everything Just Work now.
 *
 * Revision 1.16  93/03/18  03:23:24  wollman
 * Still having problems with RNR conditions.  Basic problem: say we
 * set TCP window to 16k, which is a semsible value.  Then smart
 * partners will blast 16k to us, of which we can fit 8k minus a bit
 * into our buffers.  (Need to look at that memory map..)  So, we get
 * an RNR interrupt.  The problem is, what do we need to do in this case?
 * The original code doesn't work, but it doesn't hang the system either.
 *
 * Revision 1.15  93/03/18  02:37:00  wollman
 * Disabled watchdog timer.  This gets called from a timeout somewhere,
 * which is running up at softclock.  This is at a higher priority than
 * we are, so we can get interrupted in the process of receiving something
 * by the timer expiration, which is not a nice thing to have happen.
 * Question: how can we keep this functionality, but do it in sync with
 * our interrupts?  (Ugh!)
 *
 * Revision 1.14  93/03/18  02:35:46  wollman
 * Fixed some more problems with receive code---it works!
 *
 * Revision 1.13  93/03/17  20:15:59  wollman
 * Think we fixed the serious (showstopper) bugs in 1.12.
 *
 * Revision 1.12  93/03/15  17:45:39  wollman
 * Changed filtering logic dramatically to avoid the unnecessary copyin
 * for BPF or multicast routing when the packet is not for us.  (We
 * have to run in promiscuous mode in this case.)  We still need to
 * deal with the problem of allocating one mbuf per receive buffer;
 * we should be able to get away with a single mbuf for all reasonable
 * incoming packets, and using an mbuf cluster will help avoid unnecessary
 * copying of data.
 *
 * Revision 1.11  93/01/30  20:23:15  wollman
 * Fiddled with reset code to hopefully make it work better when the
 * watchdog timer expires.  Question: why does it make a difference that
 * we do the same thing through ieioctl() as we were doing before.  The
 * old code, when iereset() was called, the receive unit would completely
 * die.  But, a cycle of ifconfig ie0 down ; ifconfig ie0 up' would bring
 * things back to normal.  So, we try to mimic that now.  Grrr...
 *
 * Revision 1.10  93/01/29  17:26:50  wollman
 * Finally fixed multicast routing/BPF mb_map full problem!!!!
 * It turned out that, when we received a packet not for us, we
 * would just return from ie_readframe(), *WITHOUT* freeing the
 * mbuf that the packet was in.  So, when running in promiscuous
 * mode (i.e., multicast routing or BPF without -p), we would have
 * (on our extremely busy subnet 4) a memory leak of epic proportions.
 *
 * We now hold on to a single mbuf chain allocated in this way,
 * and the next time a packet is read, we free it.  Also, the
 * next time a packet is transmitted, we free it.  This way,
 * we never lose more than 6 mbufs total (and on average more like
 * 3).
 *
 * Revision 1.9  93/01/23  14:22:21  wollman
 * Added some StarLAN Fiber modifications from L. Jonas Olsson.
 *
 * Revision 1.8  93/01/23  14:02:34  wollman
 * Added support for IP multicasting.
 *
 * Revision 1.7  92/11/21  17:51:59  wollman
 * Added StarLAN Fiber version point to my driver.
 *
 * Revision 1.6  92/11/20  18:21:45  wollman
 * Fixed documentation, made out-of-mbuf condition an error.
 *
 * Revision 1.5  92/11/20  18:14:02  wollman
 * Move change of ethertype to host byte order so that it's after
 * bpf_mtap.  Hopefully, this will allow us to listen to incoming
 * IP packets.
 *
 * Revision 1.4  92/11/20  18:11:00  wollman
 * Added code to drop packets when we run out of mbufs rather than
 * panicking.  This should alleviate the problems observed when using tcpdump.
 *
 * Revision 1.3  92/11/14  14:12:40  wollman
 * Added BPF support code.
 *
 * Revision 1.2  92/11/14  13:30:26  wollman
 * Added RCS keywords

Description:
	Old wt driver is too incomplete and buggy.
	It does not support Archive controllers, BSD-like
	tape ioctls, multiple tape controllers, different
	tape density etc.
Fix:
	This driver is a replacement of the old one.
	It was not tested on different controllers, though.

	This is the streamer tape driver for 386bsd and FreeBSD,
	which supports Wangtek and Archive controllers.
	It was developed as a replacement of the old Wangtek
	tape driver from CMU.

In comparison with the CMU driver, this version has the following enhancements:
1) Support for Archive SC402 and SC499 tape controllers added.
2) Support for up to three tape controllers on the same machine.
3) Support for BSD-style ioctls MTIOCGET, MTIOCTOP.
   Mt command now works adequately with this driver.
4) Asynchronous REWIND and FSF operations, close() will not wait
   until they finish.  The next open() will wait for it instead.
5) Use of WTQICMD ioctl is limited to ERASE and RETENS operations.
   This prevents the user from locking the tape driver by strange
   tape operations.
6) Tape density switching added.
7) The status of the process, blocked on the tape operation,
   is displayed at the WCHAN column of the `ps' command as:

	wtread    reading data from the tape
	wtwrite   writing data to the tape
	wtrfm     reading the tape marker
	wtwfm     writing the tape marker
	wtrew     rewinding the tape
	wterase   doing WTQICMD ERASE operation
	wtretens  doing WTQICMD RETENS operation
	wtorew    doing MTIOCTOP REW/OFFL operation
	wtorfm    doing MTIOCTOP FSF operation
	wtowfm    doing MTIOCTOP WEOF operation

Block interface (writing blocks less than 2048 bytes) is not functioning
pwoperly.  Use raw interface instead.

The only place I found with a printf("status %x") is in /sys/i386/isa/lpt.c,

And it was... I changed it to an lprintf (which is defined if debuggin is on)

I think removing FINDWORK would make things clearer.

Nothing much is going to start work on the next item.  However, it is
pointless to continue processing the queue for the same unready drive.
Aborting all reads and trying harder to perform all writes would be
better.

The fd driver reported the wrong cylinder/head/sector numbers after an
error (ST3 is only valid after a sense-drive command), and didn't report
fs block numbers (diskerr was not used).

There was an old problem with writes to block fd devices.   Try this:

1. write protect floppy in fd0.
2. tar cf /dev/fd0a /dev/null.  Repeat a few times.  Later writes tend to
   terminate earlier.
   3. un-write protect floppy.
   4. repeat step 2.  The writes tend to return 0, 2048, 4096, ... and then
      succeed.

This was caused by a bug in vfs__bios.c.  (The bug is fixed in NetBSD's
vfs_bio.c.)  fd.c sets bp->b_resid to nonzero after an error.  vfs__bios.c
was not initializing bp->b_resid.  This causes some writes to terminate
early (e.g., writes to block devices; see spec_write()).

Related funnies:

1. Nothing tries to write the residual bytes.
2. The wd driver sets bp->b_resid to 0 after an error, so there's no
   way anything else could write the residual bytes.
3. I use the block fd device for tar because the raw device seemed to
   have more bugs long ago, and because it ought to be able to handle
   buffering more transparently (I don't want to have to know the
   device size).  But spec_write() always uses the size BLKDEV_IOSIZE
   == 2048 which is too small.  For disks it should use the size of
   one track (rounded down to meet the next track boundary or the i/o
   size).  Here it would help if the DIOCGPART ioctl worked.  But
   DIOCGPART is not implemented for floppies, and the disk size is
   ignored except for partitions of type FS_BSDFFS.

message for Bruces changes:

>From: bde@kralizec.zeta.org.au (Bruce Evans)
>Subject: fixes for fd driver

I think I've fixed some bugs in the 0.2.4 fd driver.

1. The main cause of hangs was that there was no timeout for seeks.  So
   attempting i/o with no floppy in the drive hung iff a seek was required.

2. Opens of unattached drives were allowed.  The kernel usually paniced
   soon after due to a bad pointer.

3. Some timeout functions ran at splclock() instead of splbio().  This
   may not have mattered.

4. The state machine was left in a funny state after a timeout.

5. Some function headers were new-style.

6. I picked up some code posted the other day to implement label ioctls.
   Now `disklabel fd0' works.  See a comment for how to modify conf.c.

I found a bug in /sys/i386/isa/kbdtables.h which contain the
different keyboard layouts for syscons.  This regards all tables exept
the Danish and US.  When compiling the kernel with any other keymapping
than Danish or none at all (US), you get an error that 'key_map' is undefined.
This is because there is a typo in the name of the struct containing
the tables, keymap intead of key_map.
