512824f8f7 - Implement selwakeuppri() which allows raising the priority of a
thread being waken up.  The thread waken up can run at a priority as
  high as after tsleep().

- Replace selwakeup()s with selwakeuppri()s and pass appropriate
  priorities.

- Add cv_broadcastpri() which raises the priority of the broadcast
  threads.  Used by selwakeuppri() if collision occurs.

Fix a bug with the 3.3V code for the ricoh bridges.  I got the bit
detect backwards.  Also, we can only detect 3.3V cards when the GPI
interrupt is disabled.  So when it is enabled assume 5.0V card.

9f977fb187 Add support for writing to mapping high memory for pccard memory
windows.  Right now we only support pci chips that are memory mapped.
These are the most common bridges in use today and will help a large
majority of the users.

I/O mapped PCI chips support this functionality in a different way, as
do some of the ISA bridges (but only when mounted on a motherboard).
These chips are not supported by this change.

1aa3e5415e Integrate the hw.pcic.pd6722_vsense tunable from the nomads list.
This allows one to select the method of 3.3V card detection from the
three possible choices (none (0), the "6710 way" (1) and the "6729
way" (2)).  The default is the 6710 way, since it works in the most
cases.  The datasheets for the 6722 suggest that the '29 way is more
correct, but experience has shown this method to cause some laptops to
hang solid.  See source code for details until I update the man page.

d9619df632 o Remove workaround that I put in to mask the BadVcc problem.
o Add preliminary support for Cirrus Logic CL-PD6729 using PCI
  interrupts.  To use it you you need to set hw.pcic.pd6729_intr_path
  to 2.  This is allow us to still default to ISA intrrupt path for
  this part (which is found much more often in laptops using ISA IRQs).
  But some PCI cards have this part on them and this should allow them
  to be used.  It is untested on PCI, but it seems to not break the ISA
  case.
o Better sysctl descriptions (I hope).

1d88dfe265 What:
o ToPIC is happy with two cards now, even when the two cards are
	  modems.
	o Fix (all?) hangs on boot when power is applied to the card.  I
	  suspect that this will make the Ricoh bridges happier and also
	  make a lot of VAIO owners happy (confirm to me in private email
	  please :-).
	o All Cardbus bridges should now support 3.3V, X.XV and Y.YV cards,
	  to the extent that the underlying hardware supports such cards.
	  (X.X and Y.Y haven't been assigned values yet :-).
	o Better 3.3V support for Ricoh ISA bridges.

How:
	o Don't mess with the power register when scanning the cards.  It
	  is unnecessary and causes BADVcc conditions on many chipsets.  These
	  in turn can cause an interrupt storm.
	o Make pcic_disable reset the slot's voltage.
	o Move initializing voltage for the slot until after it has been
	  disabled.
	o Fix a lot of issues with the pcic_cardbus_power routine.  We
	  now properly enable the card and take it out of reset after
	  a power change.
	o When detecting the card's voltage, if we're in a BadVcc state,
	  direct the bridge to rescan the card for what it supports.
	  (we might need to in the future set the power register to 0
	   before doing this).
	o Don't preserve CLKSTOP.  need to revisit this.
	o Better support for Ricoh ISA bridges for 3.3V cards.
	o Don't write to PCIC_POWER directly as offten, but instead go
	  through the pcic_power interface.
	o All cardbus bridges now default to use cardbus power control.
	o Add misc register definitions.
	o remove some (now) bogus comments.

296596145c The datasheet for the 6710/6722 says that you must use one method to
detect 3.3V cards for the 6710 and another method for the 6722.  This
latter method is also how the 6729/6730 is supposed to detect 3.3V
cards.  This method works great on my Fujitsu Stylistic 500.  Sadly,
it appears that not all laptop makers are as detail oriented as the
folks that made the Stylistic.  IBM Thinkpad 701C and AST Asentia 810N
both hang hard when the 6729 method is used, but at least the thinkpad
works when the 6710 method is used.  The failure mode appears to be any
access to the memory that we've mapped the CIS in causes the machine to
hang until you eject the card.  The Thinkpad, at least, works with this
change, and it doesn't break my Stylistic.

99b8465544 Introduce the concept of "default" voltage. Have pccard layer use this
value (-1) in lue of 50 (which assumes a 5.0V card).  The rest of the
pccard system doesn't detect the proper voltage for the card, so we have
to do it on powerup.  Many (all?) 3.3V cards can tolerate 5.0V for reading
the CIS, but may fail to operate properly when so powered.

3761b249c9 Fix the 3.3V support for Cirrus Logic CL-PD6710. This appears to work
on my CL-PD6722, but won't work on the CL-PD6729.  The latter two need
more sophisticated detection of 3.3V cards than I'm up to at the
moment.  Also, only a few of the ISA chipsets that support 3.3V will
likely work at the moment.

It appears that for 3.3V cards we must detect them and adjust the
pwr.vcc value from 50 to 33.  Give a strong hint to automatically
power up the card for PD_POWER cards.

This makes my SMC 2602W (the 3.3V version of the 2632W) work on my

again?  That NEVER works!"  "This time for sure!"

Minor overhaul of how we do interrupts for the pci interrupt routing
case to cope with card ejection better (read: make it not hand on so
many cards):
	o Reintroduce func_intr and func_arg and use the to store the
	  interrupt handler to call.
	o Create a pcic_pci_func_intr to call the real interrupt handler
	  iff the card hasn't been ejected.
	o Remove some checks in pcic_setup_intr now that it is used
	  exclusively for isa routed interrupts.
	o Defer the eject event until later too, but make sure we can't
	  do any client driver ISR calling in the interrum.
	o Add some simple code to make sure that we don't attach more
	  than one child.  This should fix pccardd starting twice
	  problem (ala single user -> multi-user when you started pccardd
	  by hand in SU).

Warner Losh
592823383b Move to using a chip function + function pointers to deal with the
function and csc interrupt routing path (eg, ISA or PCI) so that we
can more easily switch between the two.

When we don't have a card ISR, put the function interrupt into ISA
mode.  This effectively masks the interrupt since it happens once, and
not again until we have an ISR.  This should help hangs, and might
help people that unwisely update the kernel w/o updating pccardd.
This is done at mapirq time.

Force CL-PD6729/30 to use ISA interrupt routing and maybe even detect
the number of pccard slots properly (this is still WIP).  We aren't
going to support PCI interrupts for this release.  A future release
should support them, however.  Shibata-san's 3.3V fixes are not
included.

Add a hack which should, in i386, rewrite IRQ 0 cardbus bridges to be
IRQ 255, which should cause interrupts to be routed.  This is mostly
untested since my one tester disappeared after reporting nothing
changed.

Implement, but do not use, a power method called cardbus.  It looked
like a great way to get around the 3.3V problem, but it seems that you
can only use it to power cardbus cards (I get no CIS when I enable it,
so maybe we're programming things bogusly).

GC the intr and argp stuff from the slot database.

Improve the ToPIC support with the power hacks that Nakagawa-san
published in FreeBSD Press and that Hiroyuki Aizu-san ported to
-stable.  The ToPIC hacks were for 3.3V support in ToPIC 100, but it
looks like the '97 also has identical registers, so use them too.

Add some #defines for the cardbus power stuff.

Finally implement making CSC on the Ricoh chips ISA or PCI.  This will
allow polling mode to work on vaios, I think.

Add some minor debugging.  This should likely be cleaned up or put
behing a bootverbose.

Some of this work, and earlier work, was influanced by Chiharu
Shibata-san's power handing patches posted to bsd-nomads:15866.

0d3576d9bc Now that we are setting a bit in the PCIC_INT_GEN (0x3) register, we
can't blindly write zero into it to disable the card.  We must
preserve this bit.  This changes pcic_disable to only clear the bits
we know we need to clear on card disable, thus preserving the magic
bit for many TI bridges.

This appears to have fixed the problems that people are reporting
about the system failing to recognize cards being inserted or removed
(or both).  Greg: This may fix your problem too :-).

53af1c8a3d TI cardbus bridges, 12xx and newer, have an interesting register. It
is the diagnostics register at offset 0x93.  When bit 5 is set in this
register, bits 4-7 in ExCA register 0x5 being 0000 are required for
pci interrupt routing.  When it is clear, then bit 4 of ExCA register
0x3 is used to enable it.

The only other issue is that when you route interrupts this way, you
must read ExCA register 0x4 in order to clear the interrupt, else you
get an interrupt storm.

Deal with this requirement by setting things up.  It is believed that
this won't hurt other chipsets, but other chipsets may require their
own work arounds.

o Only preallocate a resource in probe if we're routing via pci.

			interrupt (aka card status change or CSC interrupt)
			This is what used to be known as
			machdep.pccard.pcic_irq (which has been retained for
			now for compatibility).
hw.pcic.ignore_fuction_1 Ignores function 1 for all PCIC bridges by not
			attaching to them.  Lucent released a huge batch
			of cards that were imporperly manufactuered (lacking
			the 0 ohm resister to disable slot 1).  This is
			a big hammer to keep those cards from causing problems
			(I've had 4 people contact me saying my patches
			worked great once they added a kludge to always ignore
			function 1, or until they soldered these resistors
			in place!).

No clue where to document these.  They act as both boot loader environment
variables, as well as read-only sysctls after boot.

At the same time, sort sys/systm.h in its proper order after sys/sysctl.h.

c1c1a23f53 Attempt to fix and document interactions between suspend/resume and pccardc
power x 0.

pccardc power x 0 used to disable the slot.  But a suspend/resume
would reactivate the pccard.  It no longer does that.  Now the
disabling of the slot is sticy until it is reset with power x 1 or the
card is ejected.  This seems closer to correct behavior to me.

o Process all card state changes the same using pccard_do_stat_change().
o Cleanup disabling the card so that we can preserve the state after
  the change.  Basically, don't set it to empty as often as we do.
o On suspend, the new state is "empty" and the laststate is "suspend"
o Document state machine with a diagram of states and edges.  The
  edges are labeld to tell the reader what event causes the external
  state changes.
o "machdep.pccard.pcic_resume_reset" may be obsolete now.  We always
  call the bridge driver's resume method on resume now.  Otherwise cards
  won't automatically show up.  If it needs to stay, I'll add it back.

6, configure it.  All the mapping is done just before we set the

94b197e96d Move the pcic interrupt from pcic.c to pcic_isa.c. The ISA handling
for card change interrupts is different than the pci stuff that's
coming soon.  Set the management irq in different ways.  If
pci_parallel interrutp routing, then use the PCI way of getting
interrupts.  Move polling mode into pcic_isa since when we're routing
via pci polling doesn't work because many bridges (systems hang solid).

If we're routing interrupts via pci, they can be shared, so flag them
as such.

Note, this doesn't actually change anything since the pci attachment
isn't quite ready to be committed.

f83a4e8171 Turns out that one bit isn't enough. Introduce two new fields
csc_route and func_route to hold the way that each interrupt is
routed.  csc is Card Status Change in the datasheets and standard, but
is called "Management Interrupt" in FreeBSDese.  There are three types
of interrupt routing:  ISA parallel, PCI parallel and ISA serial (some
chipsets support other types as well, but I don't plan on supporting
them).

When we try to allocate an interrupt, and the type for that interrupt
is pci_parallel, allow it to be shared by oring in RF_SHAREABLE to the
flags argument.  Introduce pcic_alloc_resource to allow this to
happen.
