the inter-value histogram for 2000 samples. If the width is 3 or less
for 10 consequtive samples, we trust the counter to be good, otherwise
we use the *_safe() method.
This method may be too strict, but the worst which can happen is that
we take the performance hit of the *_safe() method when we should not.
Make the *_safe() method more discriminating by mandating that the three
samples do not span more than 15 ticks on the counter.
Disable the PCI-ident based probing as a means to recognize good
counters.
Inspiration from: dillon and msmith
latch the acpi timer, resulting in weird deltas. The problem is severe
enough to adversely effect the timecounter code.
Default to the 'safe' version of the get-timecount function. The probe
will override it if a known-good chipset is found. This is temporary
until a more complete solution is found.

AIOGCAP ioctl reports software-emulated formats. It defaults to on. People
who use performance-sensitive audio software and do not want it to pick a
software-emulated audio format instead of one supported by their hardware
should turn it off.

New locks are:
- pgrpsess_lock which locks the whole pgrps and sessions,
- pg_mtx which protects the pgrp members, and
- s_mtx which protects the session members.
Please refer to sys/proc.h for the coverage of these locks.
Changes on the pgrp/session interface:
- pgfind() needs the pgrpsess_lock held.
- The caller of enterpgrp() is responsible to allocate a new pgrp and
session.
- Call enterthispgrp() in order to enter an existing pgrp.
- pgsignal() requires a pgrp lock held.

OUT status. We are, apparently, required to force the f/w to log back in
if we want to try and talk to that disk again. This means either issuing
a LOGIN LOCAL LOOP PORT mailbox command, or by issuing a LIP. I've elected
to issue a LIP because this has a better chance of waking up the disk which
clearly just crashed and burned.
These should not occur at all. If they do, they should be darned rare.

to be able to use 48bit addressing mode, but says the 48bit
size of the disk is 0, which according to spec means it can
address zero sectors in 48bit mode, why then say it supports
48bit mode at all..
If you want QLogic to look at a potential f/w problem for FC cards, you really
have to provide them info in the format they expect. This involves dumping
a lot of hardware registers (> 300 16 bit registers) and a lot of SRAM
(> 128KB minimum). Thus all of this code is #ifdef protected which will
become an option so that the memory allocation of where to dump the crash
image is pretty expensive. It's worth it if you have a reproducible problem
because they have some tools that can tell them, given the f/w version,
the precise state of everything.

Appologies for making this one bulk commit, but I have tested all these
changes together and don't want to break anything by trying to disentangle
it.
o Make debugging a sysctl/tunable
o Remove flags word from yenta chip info, it is unused
o Make 16-bit card I/O range and 32-bit card I/O range tunables
o Start the rename of pccbb to cbb to match NetBSD by misc renames.
o Kill the now bogus list of softcs to create kthread. Instead, just
create the kthread in the attach routine.
o Remove sc_ from some structure names. It isn't needed.
o Refine chipset lookup code.
o Match generic PCI <-> CardBus bridges. We specifically don't generically
match PCI PCMCIA bridges because they are not, with one exception, yenta
devices.
o Add some comments about the why we need to have a function table ala
OLDCARD
o The PCI interrupt routing by using the ExCA registers is needed for
for all bridges, per the spec, not just TI ones.
o Collapse TOPIC95 and TOPIC95B.
o Using the ToPIC 97 and 100 datasheets, try to support these bridges better,
but more work is needed.
o Generally clarify some XXX comments and add them in a few places where
things didn't look right to me.
o Move interrupt generating register access until after we establish an ISR.
o Add support for YV and XV cards. X and Y are numbers to be determined
later (but maybe never).
o factor powerup code for 16-bit and 32-bit cards.
o When a card supports more than one voltage, prefer the lowest supported
volage. Windows does this, and MS's design guides imply this is the
right thing to do.
o Document race between kthread_exit(0) and kldunload's unmapping of pages
that John Baldwin and I discovered.
o Debounce the CSC interrupt a little better.
o When a 16-bit card is inserted when we don't have a pccard child,
warn about it better. Ditto for 32-bit card.
o Ack ALL the interrupt bits that we get, not just 0x1.
o maybe a couple minor style nits corrected.
the structure definitions come from NetBSD to make it easier to share card
definitions. The driver only acts as a shim between the pci bus and the
sio driver. Later pci parallel ports could also be supported through this
driver. Support for most single and multiport pci serial cards should be
as simple as adding its definition to pucdata.c
Tested with the following pci cards:
Moxa Industio CP-114, 4 port RS-232,RS-422/485
Syba Tech Ltd. PCI-4S2P-550-ECP, 4 port RS-232 + 2 parallel ports
