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.
it breaks in the DEVFS_ROOT case. replicate a bit too much of bdevvp()
in here to circumvent the problem. The real problem is the magic that
lives in bdevsw[1].
Opening the socket is the only privileged operation route requires.
Make a couple of static buffers bigger, and use strncpy() and snprintf() where
there's a chance of overflow.

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.

and YP_SECURE flags so that it can properly add them to newly created
maps when needed. This applies only when using the 'standard' method
for map transfers. When using rpc.ypxfrd, the whole map is copied
verbatim, along with any special entries that may be encoded in it.
Also made -Wall a little quieter for ypxfrd_getmap.c.
Fixed some style bugs for cua* and tty*.
Removed superfluous chmod for consolectl.
FIxed a tiny security bug for perfmon and changed the style for
perfmon to match the style of the non-std devices.
so that simple regresssion tests based on `cmp' work. mkdep still
doesn't work right for these tools. They should probably be in
separate directories.
Sorted dependencies.
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.
break when I remove LOCORE support from clock.h.
I586_CTR_MULTIPLIER_SHIFT = 32 from clock.h is actually still used, but
32 is so magic that it doesn't get used explicitly.
- 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.
