37bd2b301c Fix braino on my part. When we have three different port ranges (default,
"high" and "secure"), we can't use a single variable to track the most
recently used port in all three ranges.. :-]  This caused the next
transient port to be allocated from the start of the range more often than
it should.

b36b7d853f Add basic support for the 398X cards as multi-channel SCSI host adapters.
This involves expanding the support of the SEEPROM routines to deal with
the larger SEEPROMs on these cards and providing a mechanism to share
SCB arrays between multiple controllers.

Most of the 398X support came from Dan Eischer.

1affda38c1 Add two new aic7xxx driver options:
AHC_FORCE_PIO - This forces the driver to use PIO even on systems that
	say they have memory mapped the controller's registers.  This
	seems to fix Ken Lam's problems.  I've also placed this option
	in the GENERIC kernel file so that we are guaranteed to install
	even on these flakey machines.

AHC_SHARE_SCBS - This option attempts to share the external SCB SRAM on
	the 398X controllers allowing a totoll of 255 non-paged SCBs.
	This doesn't work quite yet, so this option is mostly here to
	help 398X owners to experiment and give me feedback until this
	works properly.

281cd9b020 The way we get a vnode for swapdev is not quite kosher. In particular
it breaks in the DEVFS_ROOT case.  replicate a bit too much of bdevvp()

lives in bdevsw[1].

66e7fce7ac Use the calibrated/adjustable i8254 frequency `timer_freq' instead of
TIMER_FREQ.

Fixed missing splx() in scrn_timer().  The bug was harmless because of the
undocumented behaviour that the ipl is automatically restored for timeout
functions (see softclock()).  Perhaps we should depend on this behaviour.

Fixed the ddb fix in rev.1.176.  The in_debugger flag was no use because
it only works when the debugger is entered via the keyboard hotkey.  The
debugger may be entered for breakpoints and traps, and the console putc
routine has no way of knowing when it was, so the console putc routine
must (almost?) always remove the cursor image.

Not fixed: console switching in ddb doesn't work (ISTR it working), and
console 0 shouldn't be switched to for the debugger hotkey unless console
0 is /dev/console.

Fixed side effects from calling add_keyboard_randomness() in the console
getc routine by not calling it.  add_keyboard_randomness() currently
always reenables interrupts on 386's and 486's.  This is very bad if the
console getc routine is called from the debugger and the debugger was
entered with interrupts disabled.

Fixed preservation of initial screen and now-bogus comment about it.  It
was broken by setting the initial scr_buf to `buffer' instead of Crtat.
`buffer' was full of nulls and the first scroll cleared everything above
the things written through syscons.

835bd1ce62 Improved biasing of i586 clock by adjusting for hardclock() latency.
I decided to do this for every hardclock() call instead of lazily
in microtime().  The lazy method is simpler but has more overhead
if microtime() is called a lot.

CPU_THISTICKLEN() is now a no-op and should probably go away.
Previously it did nothing directly but had the side effect of
setting i586_last_tick for CPU_CLOCKUPDATE() and i586_avg_tick for
debugging.  CPU_CLOCKUPDATE() now uses a better method and
i586_avg_tick is too much trouble to maintain.

Reduced nesting of #includes in the usual case.

Increased nesting of #includes when CLOCK_HAIR is defined.  This
is a kludge to get typedefs for inline functions only when the
inline functions are used.  Normally only kern_clock.c defines
this.  kern_clock.c can't include the i386 headers directly.

Removed unused LOCORE support.

32 is so magic that it doesn't get used explicitly.

df9ab5b30f - KNF cleanup.
- Add support for memory mapped I/O.
- Use DMA to get SCBs down to the adapters.
- Remove old paging code.
- Be much smarter about how we allocate SCB space.  The old, simple method
  wasted almost half a page per SCB. Ooops.
- Make command complete interrupt processing more efficient.
- Break the monolithic ahc_intr into sub-routines.  The sub-routines handle
  rare, special case events so the function call is not a penalty and the
  removal of the code from the main routine most likely improves performance
  instruction prefech will work better and less code is pushed into the cache.
- Never, ever allow tagged queueing if a device has disconnection disabled.
- Clean up and simplify timeout code.  Many of the changes are to handle the
  new DMA scheme.

971791f48d Go back to using DMA to get SCBs down to the adapter.
SCB paging is now handled almost entirely by the sequencer and also uses
DMA.  This should make SCB paging at least an order of magnitude more
efficient and vastly simplifies the implementation.
