e228c81074 Fix the GUS driver so that it will initialize properly from power-on...
no more DOS boots to start it up.

Simply did a localized nuke of the OUTB macro in this file.  This is
a kludge, since it seems it may actually be necessary in other GUS
files (tbd).

Thanks to: Amancio Hasty & Ken Hornstein

f73f117cf0 Don't allow negative console numbers for the VT_WAITACTIVE ioctl. Use the
correct console number for the VT_WAITACTIVE ioctl.  Invalid console numbers
caused waiting on an invalid pointer.

Use bcopyw() instead of move_up() and move_down().  bcopyw() handles
overlapped copies and should be faster.  Actually use bcopy().  bcopy()
is slightly faster if video memory is 16-bit and about twice as fast if
it is 32-bit.  bcopy() is said to fail on someGA's, but syscons already
depends on it working for other accesses to video memory.

37e52b59cc Use sufficient parentheses in macros.
Remove bogus input operands for fnsave(), fnstcw() and fnstsw().

Change all fwait's to fnop's.  This might help avoid hardware bugs.
Wait after fninit with an fnop.  This should be safer now.

Fix some spelling and formatting errors.

Use natural sizes for control and status words (u_short, promotes to int).

Don't clobber the SWI_CLOCK_MASK bits in npx0_imask when using IRQ13.

Set the devconf state correctly (always busy, if configured).  Improve
code for npx_registerdev() a little (gcc can't keep id->id_unit in a
register for some reason).  Don't register a nonexistent npx device.

Print a useful message in npxattach() again (delete references to errors
and not the whole message).  Don't print "387 emulator" if there is no
emulator in the kernel.

Use %p for pointers in error messages.

Don't clobber the FPU state when there is an FPU exception.  Just clear
the exception flags (after saving the flags as before).  This allows
debuggers and SIGFPE handlers to look at the full exception state.
SIGFPE handlers should normally return via longjmp(), which restores a
good FPU state (as before).  Returning from a SIGFPE handler may leave
the FPU in the wrong state (as before).

Clear the busy latch _after_ clearing the exception flags so that there
is less chance of getting a bogus h/w interrupt for a control operation.

Clear the saved exception status word when the next FPU instruction is
excuted so that it doesn't stick around until the next exception.

Clear the busy latch after fnsave() in npxsave() in case it was set when
npxsave() was called.

53a69701bc Handle both channels of Twin channeled devices. Respect the configuration
values for syncronous negotiation.  The 284x series adaptors can now be
supported without the Bios being enabled.  If you disable the Bios on the
274x series adaptors, all configuration parameters revert to the default
since there is no way to retrieve them.

63c5d14d1b Miscellaneous changes from Bill Paul:
- /sys/i386/isa/if_ed.c doesn't quite know how to deal with SMC EtherEZ
  ethernet cards. The EtherEZ looks just like the Elite Ultra, except it
  has only 8K of shared memory. The only way to have it properly detected
  is to zero and test a few bytes of memory just about the first 8K region.
  If it clears properly, it's an Elite Ultra, otherwise it's an EtherEZ.

  I've also got an EtherEZ patch for netboot (Makefile, ether.c and ether.h).

- /sys/i386/isa/syscons.c wraps at the next to the last column rather than
  the last column, like it should. You don't really notice this unless you
  use certain programs that write all the way out to, say, the 80th column,
  like VMSmail. Along with a one-line fix for this are some changes to
  implement a non-blinking cursor. Put 'options "NOBLINK_CURSOR"' in your
  config file and give it a try. :)

10bfdf2bae From: "Serge V.Vakulenko" <vak@gw.cronyx.msk.su>
This is new version of Seagate ST01/02, Future Domain TMC-885, TMC-950
SCSI driver for FreeBSD.  I started from the 2.0R version and mostly
rewrote it.  New features are:

1) New probe algorithm.  Old driver read the BIOS region of the adapter
   memory and find the copyright string.  The problem was in the BIOS itself:
   it conflicted with IDE disks.  The solution was to unplug it and
   make the probe algorithm to work without it.
2) Proper timeout handling in numerous places where the driver
   polls waiting for some event.
3) Assembler flagments added in critical places, mostly for data transfer
   to of from the target.  It was possible to make it faster,
   but at the price of decreasing reliability.
4) Target-dependent delays when waiting for REQ deassert event.
   Some devices seem to be slower (CD-ROMS, some tape drives),
   and some seem to be too fast (disks).  The driver tests the REQ
   deassert timeout for each target and then uses it for polling.
5) Device flags added for SCSI parity control and sense request
   priority control.
6) Generic cleanup, after which the driver became much more readable
   (at least by me:).
7) Target data parity error logging is limited to avoid log file overflow.
8) Manual page added.

43469be308 icu.s:
Move definition of `stat_imask' to clock.c.

clock.c:
Rename `rtcmask' to `stat_imask' and export it.  Rename `clkmask' to
`clk_imask' for consistency.

Only calculate TIMER_DIV(hz) once.

Merge debugging and "garbage" code to produce debugging code and format the
output better.

Make writertc() static inline and use it everywhere.  Now all accesses to
the clock registers go through rtcin() and writertc().

Move rtc initialization to cpu_initclocks().

Merge enablertclock() with cpu_initclocks() and remove enablertclock().
The extra entry point was just a leftover from 1.1.5.

b39b673d37 i386/exception.s,
Keep track of interrupt nesting level.  It is normally 0
	for syscalls and traps, but is fudged to 1 for their exit
	processing in case they metamorphose into an interrupt
	handler.

i386/genassym.c;
	Remove support for the obsolete pcb_iml and pcb_cmap2.

	Add support for pcb_inl.

i386/swtch.s:
	Fudge the interrupt nesting level across context switches and in
	the idle loop so that the work for preemptive context switches
	gets counted as interrupt time, the work for voluntary context
	switches gets counted mostly as system time (the part when
	curproc == 0 gets counted as interrupt time), and only truly idle
	time gets counted as idle time.

	Remove obsolete support (commented out and otherwise) for pcb_iml.

	Load curpcb just before curproc instead of just after so that
	curpcb is always valid if curproc is.  A few more changes like
	this may fix tracing through context switches.

	Remove obsolete function swtch_to_inactive().

include/cpu.h:
	Use the new interrupt nesting level variable to implement a
	non-fake CLF_INTR() so that accounting for the interrupt state
	works.

	You can use top, iostat or (best) an up to date systat to see
	interrupt overheads.  I see the expected huge interrupt overheads
	for ISA devices (on a 486DX/33, about 55% for an IDE drive
	transferring 1250K/sec and the same for a WD8013EBT network card
	transferring 1100K/sec).  The huge interrupt overheads for serial
	devices are unfortunately normally invisible.

include/pcb.h:
	Remove the obsolete pcb_iml and pcb_cmap2.  Replace them by
	padding to preserve binary compatibility.

	Use part of the new padding for pcb_inl.

isa/icu.s:
isa/vector.s:
	Keep track of interrupt nesting level.

72f30c2bd3 Andres Vega Garcia's improvements to the ep driver. This driver is a merging
of the 1.1.5 driver, a recent version of the NetBSD driver, Andres'
transmission start threshold code, and all other relavent changes to the driver
since it was brought into 2.0.  The multicast support from NetBSD has not be
folded in yet.  I've tested it under high loads for two weeks and it is now
robust enough to be included in the GENERIC kernel.

a3b33372b9 Maintain a new variable `timer0_overflow_threshold' so that microtime()
doesn't have to calculate it every call.

Rename `timer0_prescale' to `timer0_prescaler_count' and maintain it
correctly.  Previously we lost a few 8253 cycles for every "prescaled"
clock interrupt, and the lossage grows rapidly at 16 KHz.  Now we
only lose a few cycles for every standard clock interrupt.

Rename `*_divisor' to `*_max_count'.

Do the calculation of TIMER_DIV(rate) only once instead of 3 times each
time the rate is changed.

Don't allow preposterously large interrupt rates.  Bug fixes elsewhere
should allow the system to survive rates that saturate the system, however.

Clean up declarations.

Include <machine/clock.h> to check our own declarations.

errors at a lower ipl.  clist starvation problems can cause hundreds of
tty buffer overflows per second and logging them all amplified the
problems.  This problem was less serious in 1.1.5.

Avoid a race in the check for starting a new block of output.  com_events
was sometimes messed up and siopoll() looped endlessly.  This bug was
introduced in 2.0.

Clean up previous 2 commits.  Rename sio_registerdev() to sioregisterdev()

5d04c702eb Several minor fixes to the floppy driver:
.	avoid resetting the FDC every time the last motor is going off;
	instead, give it a 60-second period for possible later reactivation.
	This prevents us from needing to recalibrate the FDC too often,
	but still allows for an ``automagic error recovery', just in case the
	controller is absolutely stuck. (Simply wait for 60 seconds, and
	try it again.)

.	made the floppy head settle time after a seek a constant
	that might be overridden by a config option. (Well, actually the
	divisor of the settle time). Pepople often reported problems with
	their floppies, so i need a simply mechanism that allows them
	to play with that value. (I personally cannot find any problem
	on *my* drives.)

.	implement the FD_DEBUG ioctl command, in case the driver
	is compiled with DEBUG turned on.

.	removed a bogus parameter from a printf; the remaining warnings
	from gcc -Wall seem to be warnings about the %b format gcc cannot
	understand

.	rearrange Garett's code to fit better in the existing structure
	of #define/type/function ordering.

.	make everything fit into 79 columns again.

 I got no output :-(

 Thus, I'm forced to concluded that something else is examining some

 On the premise that such an initialization isn't going to hurt anything,

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.

This is the slowest and most stupid of our SCSI-drivers, but it is there

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.

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.

0e195446b7 Bug fixes and performance improvements from John Dyson and myself:
1) check va before clearing the page clean flag. Not doing so was
	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.

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

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.

3b2acd20e0 1) My previous fix does nothing, now Rod's fix rewrited to implement
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...

Small hack, if heads > 16, output a warning and then set the head

people to later fix the DOS parameter table later with fdisk.

f2ba1017cc Increase the timout on aha_send_mbox from 1ms to 3ms, needed to reliably
run Exabyte 8505 on 1742's.  This may not be the final solution, but it
makes it work.  It may be better to change the DELAY(10) to DELAY(30)
inside the loop instead of increasing the loop count from 100 to 300.
