27ef9ec914 Support PnP compatibility IDs. This allow e.g. the ed driver to pick
up any PnP NE2000 compatible card, instead of forcing us to always
update ID lists.

35fa873125 Added D_TTY to the cdevswitch flags for all tty drivers. This is required
for the Lite2 fix for always returning EIO in dead_read().

Cleaned up the cdevswitch initializers for all tty drivers.

Removed explicit calls to ttsetwater() from all (tty) drivers.  ttsetwater()
is now called centrally for opens, not just for parameter changes.

1524621152 Enabled dynamically sized tty input buffers (with enough buffering
for 1 second's worth of input) and larger tty output buffers.  The
interrupt-level buffers are still too small for speeds above 115200
bps (only a little too small for 230400 bps if RTS flow control is
enabled).

Don't call ttsetwater() explicitly in open().  It is now called for
the TTYDISC l_open() and should be static.

Don't attempt to register the cdevsw more than once.

d22b2d54d1 Register tty software interrupt handlers at run time using register_swi()
instead of at compile time using ifdefs.

Use _swi_null instead of dummycamisr.  CAM and dpt should call
register_swi() instead of hacking on ihandlers[] directly.

0fd89b46c5 Don't log "unexpected" events on never-opened devices. Events left
over from the probe are now expected for incompatible UARTs that
deliver IRQs as a strobe (low) instead of a level (high).

Discard events on going-away devices too.  Endless loops may have
been possible when an active pccard was removed.

1d5f38ac22 This commit fixes various 64bit portability problems required for
FreeBSD/alpha.  The most significant item is to change the command
argument to ioctl functions from int to u_long.  This change brings us
inline with various other BSD versions.  Driver writers may like to
use (__FreeBSD_version == 300003) to detect this change.

The prototype FreeBSD/alpha machdep will follow in a couple of days
time.

0d80f93df9 Force success of the probe (after doing it as before except in one
miscconfigured case) if the port is the console.  This fixes several
bugs:
- if all sioprobe()s failed, then the console driver followed null
  pointers in cdevsw[].
- if the sioprobe() for the console failed but another sioprobe()
  succeeded, then init hung early when the console couldn't be
  opened.
- it was silly for the console to not be there after printing boot
  messages on it.
Bugs introduced by this are hopefully no worse than old ones caused
by forcing the success of the `cn' level probe.

e32c63389f Fixed a printf() arg botch in the previous commit.
Only complain about an irq mismatch in the probe if the configured
irq doesn't become active, and then print the bitmap of irqs that
became active (including clock irqs) instead of just the first
(not including clock irqs).

ec6c6de5c6 Converted the ICU-level interrupt tests (3, 5 and 8) in sioprobe() into
a test of the irq number, and made failure of this test non-fatal.
Removed related unused complications for the APIC_IO case.  Removed the
no-test3 flag.

Deverbosified the failure messages for the other tests.  Removed the
per-port verbose flag - just use the general verbose flag.

driver 'break out' of the infinite loop waiting for a response from

 * Use the #defines for the hotchar in the SLIP and PPP line disciplines

c4f9529d8c Fixed initialization of the divisor latch. We depended on siocnopen()
initializing it for the (usual) (siocniobase != 0) case, but
siocnopen() doesn't initialize it if the latch registers already
have the correct values.

6923614d1d Always call ttwwakeup() before returning from comstart(). It isn't
necessary to call it when the tty layer's output state has not been
changed, but siostop() sometimes changes the TS_BUSY state and then
calls comstart() mainly for its side effect of calling ttwwakeup().

fa55951ed5 - Instead of relying on a functional call to register PCARD-capable drivers,
use a Linker Set.  Note, if a driver is loaded as an LKM  if will have
  to use the function call, but since none of the existing drivers
  are loadable, this made things cleaner and boot messages nicer.

2f55d3018b - Functional changes to PCCARD support.
* Kill individual drivers 'suspend' routines, since there's no simple/safe
   way to suspend/resume a card w/out going through the complete probe
   at initialization time.
 * Default to using the apm_pccard_resume sysctl code, which basically
   pretends the card was removed, and then re-inserted.  Suspend/resume
   is now 'emulated' with a fake insert/removal.  (Hence we no longer
   need the driver-specific suspend routines.)

   naming schemes.
 * Rename a bunch of parameter and local variable names to be more
   consistant in the code.
 * Renamed the PCCARD 'crd' device to be the 'card' device
 * KNF and make the code consistant where it was obvious.

13be81370a teach sio how to attach to isa PnP cards. This is mainly for use with
internal modems.  Currently detects a USR modem, and a couple Supra
modems...  vendor id's for sio capabile cards welcomed...

document new option EXTRA_SIO that will increase sio's internal data
structures to support X more serial ports...  these are used by the
PnP part of sio for attaching...  If you don't have it specified, it
will default to 2...  This is defaulted to 0 if you don't have PnP
compiled into your kernel...

also document that if you set the PnP flags (pnp x flags y) to 0x1 that
the modem will be refused to be recognized by the sio driver... this
is for people that want the traditional isa driver to probe and attach
the modem... (for keeping legacy sio numbering)

92287f9b58 Created a private simple_lock to control accesses to com data structs
and hardware.
There is now another simple_lock around clock data/hardware accesses in
clock.c and microtime.s.  It is my belief that this is the only area
sio/cy might stumble into during an unblocked INTerrupt.  Thus I separated
the sio/cy code from the generic disable_intr()/enable_intr() routines.

Controlled by smptests.h: USE_COMLOCK, ON by default.

e2310cdbcf Another round of lock pushdown.
Add a simplelock to deal with disable_intr()/enable_intr() as used in UP kernel.
UP kernel expects that this is enough to guarantee exclusive access to
regions of code bracketed by these 2 functions.
Add a simplelock to bracket clock accesses in clock.c: clock_lock.

speed using the boot blocks, instead of a hardcoded value stuck in the
