bfd8c5ea31 For TI12xx and newer, clear register 0x84. This is the "Multimedia"
register.  It enables Zoom Video.  It appears that on at least one
card that Monzoon is using sets these bits by default.  Nothing works
when these bits are set, everything works when they are clear.

Add commentary on some of the ti bits.  Make code a little clearer.
Also remove a call to pcic_pci_pd6729 which was prematurely added in
the last commit.

101574484a 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 :-).

15c0c44955 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.

7ffebadcef A bunch of interrupt related cleanup.
o Move PIOCSRESOURCE from pccard to pcic so the kernel can give pccardd
  better hints as to what resources to use.
o Implement an undocumented hw.pcic.interrupt_route to allow people that
  need to do so to route their interrupts in a non-standard way.
o Only preallocate a resource in probe if we're routing via pci.
o If we aren't routing via pci, then set the irq to use explicitly
  to defeat the automatic IRQ routing of the pci layer.

This, with the pccardd code should be close to what can be committed
to -stable.

0774b50fdd Introduce two new tunables from the boot loader.
hw.pcic.irq		Globally set the IRQ for all pcic devices' management
			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.

5323d94f50 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.

to make the insert/remove events more reliable after a resume as well,
but that may be a different bug I need to hunt down.

16840ac973 Make the multiple interrupts attachment an error not a panic.
Sometimes, when pccardd is restarted, it fails to realize that the
device is already attached and tries to attach it again.  This leads
to bad mojo since the pccard code isn't setup to handle that, so the
panic was put in.  Now it appears that it is triggering too easily, so
I'm backing it off to a non-fatal error.

aef6e26169 Some interrelated interrupt changes.
Frist, for pci slots, make the setup intr save the requested interrupt
vector and arg and return rather than passing it up to our parent.  On
interrupts, we call this vector iff there's a card in the slot.  This
should eliminate some of the hangs or "weird" messages that people see
when ejecting cards and also help close the race window somewhat.
Reading the pci bus one more time for this information is judged to be
an acceptible tradeoff since it is very very fast.

Cleanup a little how we detect unsupported cards.  Only detect
unsupported cards (eg cardbus cards) on card insertion (or more
pedantically when a card is actually present).  This should allow us
to change the message in the future to "cardbus card not supported
with OLDCARD" :-).

Note:
	We may also consider this for the ISA bus case, but there the
	reads are much more expensive and the location of the CD pin
	status lines appears to be less standardized.  Also, the ISA
	management interrupt isn't shared with the card's interrupt.
	The mutliplex the CSC and function interrupts bit also appears
	to be non-standard (or at least not imlemented on all
	bridges).

128e29a1c0 Write zeros into the base/bounds register bars. We need to do this
because NEWBUS (and I think some versions of Windows sometimes) writes
0xffffffff to these registers to disable them.  When they are
"disabled" like this, writing memory ranges to the pcic registers are
ignored and you will get "card (null) (null)" when you insert a call
otherwise.

9c03640f81 Work around a bug in the current interrupt system by explicitly
rejecting INTR_FAST interrupts.  Since they can't be shared anyway,
this just short circuits a failure case that should work but is panic
fodder now.

This bug is that if the interrut condiation is active when you activate
the interrupt, then the interrupt routine will be called.  jhb had
a patch that may or may not work to fix it, but I've lost it.

This may be due to the sio probe doing something odd too.

2819707a6c On PC-98, map IRQ 6 to IRQ 7 at the pcic level. That is, when we're
told to use IRQ 6, progam the pcic to use irq 7 instead.  Evidentally,
at least some of the cards are wired this way.  If you want to use irq
6, configure it.  All the mapping is done just before we set the
interrupt registers.  See [FreeBSD98-testers 5064] for details.

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

476e3d24e2 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.

39ce0c191f Next step on the road to pci: power taming.
Work through the various power commands and convert them from a "is
this a foo controller or a foo' controller or a foo''' controller" to
a cabability based scheme.  We have bits in the softc that tell us
what kind of power control scheme the controller uses, rather than
relying on being able to enumerate them all.  Cardbus bridges are
numerous, but nearly all implement the i82365sl-DF scheme (well, a few
implement cirrus CL-PD67xx, but those were made by Cirrus Logic!).

Add a pointer back to the softc in each pcic_slot so we can access
these flags.

Add comments that talk about the issues here.  Also note in passing
that there are two differ Vpp schemes in use and that we may need to
adjust the code to deal with both of them.  Note why it usually works
now.

We have 5 power management modes right now: KING, AB, DF, PD and VG.
AB is for the i82365 stpes A, B and C.  DF is for step DF.  PD is the
cirrus logic extensions for 3.3V while VG is the VADEM extensions for
3.3V.  KING is for the IBM KING controller found on some old cards.
# I'm looking for one of those old cards or a laptop that has the KING
# bridge in it.

We have to still cheat and treat the AB parts like the DF parts
because pci isn't here yet.  As far as I can tell, this is harmless
for actual old parts and necessary to work with 3.3V cards in some
laptops.

This almost eliminates all tests for controller in the code.  There
are still a few unrelated to power that need taming as well.

c647eb3dd3 Next step towards pcic_pci: the ability to allocate mapped memory in attach.
o Introduce flags word to the softc.  This will be used to control various
  aspects of the driver.  Right now there are two bits defined, PCIC_IO_MAPPED
  and PCIC_MEM_MAPPED.  One for ISA cards that are I/O mapped, the other is
  for PCI cards that are memory mapped.  Only the ISA side is implemented
  with this commit.
o Introduce a pcic_dealloc which will cleanly dealloc resources used.  Right
  now it is only supported when called from probe/attach.
o Keep track of resources allocated in the pcic_softc.
o move pcictimeout_ch to the softc so we can support multiple devices
  in polling mode.
o In ISA probe, set PCIC_IO_MAPPED.
o Introduce and compute the slot mask.  This will be used later when
  we expand the number of slots on ISA from 2 to 4.  In such a case, we
  appear to have to use polling mode otherwise we get two different cards
  trying to drive the same interrupt line.  I don't have hardware to
  test this configuration, so I'll stop here.

26885aebf5 It turns out that Intel's i82365sl-DF step has the same ID as the VLSI
82C146.  The Intel i82365SL-DF supports 3.3V cards.  The Step A/B/C
parts do not appear to support this.  This is hard to know for sure
since it was deduced from "compatible" parts' data sheets and the
article mentioned below.

Rework the VLSI detection to be a little nicer and not depend on
scanning cards twice.  This would allow bad VLSI cards to coexist with
a good intel card, for example.  We now detect i82365SL-DF cards where
before we'd detect a VLSI.  For the most part, this is good, but we
run a small chance of detecting a single slot 82C146 as a i82365SL-DF.
Since I can't find a datasheet for the 82c146, I don't know if this is
a problem or not.

This work is based on an excellent article, in Japanese, by NAKAGAWA,
Yoshihisa-san that appeared in FreeBSD Press Number 4.  He provided a
patch against PAO3 in his article.  Since the pcic.c code has changed
some since then, I've gone ahead and cleaned up his patch somewhat and
changed how the code detects the buggy '146 cards.

I also removed the comment asking if there were other cards that
matched the 82C146 since we found one and additional information isn't
necessary.

1d2e092aa3 Fix the so called "static bug" in polling mode. Some desktop cards
have bad grounding characteristics which allow small static discharges
(or sunspots, we're not 100% sure which) to reach the bridge chip.
This causes the bridge chip to wedge/reset itself.  There's no known
cure short of rebooting.

The bug manifests itself by the STAT_CHG return 0xff when read.  This
is impossible because the upper bits are reserved (and therefore
zero).  In addition, some of the lower bits are one only for memory
cards, which OLDCARD doesn't support, so if they are set, something
seriously foobar'd is going on.

So far we've seen this in exactly one brand of pcmcia <-> isa bridge
which plug and play identifies only as "VIA PCMCIA CARD".  This card
just has buffers on the isa card and the actual bridge chip on the
remote slot, which is connected by long ribbon cables.  We think this
long cable run, coupled with the lack of coupling capacitors is a
major reason why it is so static sensitive while its bretheren aren't.

o Attempt to disable the slot when we detect that there are problems with

  register to 0.  This worked for me for lots of tests in polling mode.

  have pins for these illegal interrupts, and all of them are listed as
  reserved and/or illegeal in the datasheets depending on which one you
  look at.

  map these interrupts and which ones are valid.

  value listed in the PCIC_STAT_INT register.  I've seen this bit get set

222e32bc49 Implement indirection in the pccard probe/attach. This should make it
possible to have different probe/attach semantics between the two
systems and yet still use the same driver for both.

Compatibility methods for OLDCARD drivers.  We use these routines to make
it possible to call the OLDCARD driver's probe routine in the context that
it expects.  For OLDCARD these are implemented as pass throughs to the
device_{probe,attach} routines.  For NEWCARD they are implemented such
such that probe becomes strictly a matching routine and attach does both
the old probe and old attach.

compat devices should use the following:

	/* Device interface */
	DEVMETHOD(device_probe),	pccard_compat_probe),
	DEVMETHOD(device_attach),	pccard_compat_attach),
	/* Card interface */
	DEVMETHOD(card_compat_match,	foo_match),	/* newly written */
	DEVMETHOD(card_compat_probe,	foo_probe),	/* old probe */
	DEVMETHOD(card_compat_attach,	foo_attach),	/* old attach */

This will allow a single driver binary image to be used for both
OLDCARD and NEWCARD.

Drivers wishing to not retain OLDCARD compatibility needn't do this.

62e0e10410 add PIOCSRESOURCE(IOC_GET_RESOURCE_RANGE)
Now /usr/sbin/pccardd read free resource(io,irq) range with
this ioctl.

7013b83225 - Remove the inthand2_t type and use the equivalent driver_intr_t type from
newbus for referencing device interrupt handlers.
- Move the 'struct intrec' type which describes interrupt sources into
  sys/interrupt.h instead of making it just be a x86 structure.
- Don't create 'ithd' and 'intrec' typedefs, instead, just use 'struct ithd'
  and 'struct intrec'
- Move the code to translate new-bus interrupt flags into an interrupt thread
  priority out of the x86 nexus code and into a MI ithread_priority()
  function in sys/kern/kern_intr.c.
- Remove now-uneeded x86-specific headers from sys/dev/ata/ata-all.c and
  sys/pci/pci_compat.c.

9fa779df8d Add TI-1031 id. It doesn't work yet, but it is nice to have it.
These were on cards that were pci pccard (not cardbus) bridges that
lived in SparcUltras that picked up on ebay.

1c624ac57c Add UNIX domain socket feature to pccardd. This makes pccard
related PAO3/ports such as gxcardmon work.

8f29f4ff6f Add some infrastructure support for dealing with large attribute
memory space needed by the raylink driver (in progress, nearing
completion).

This is a minorly cleaned up diff from Duncan to help him reduce the
diffs from stock FreeBSD.

add17facd3 Fix a bug so that we have correct number of pccard instances in pcic_attach().
pcic_attach() got a wrong pointer to pcic_slots since device haven't
set correct unit number yet, so always accessed elements of pcic_slots
which belong to pcic0 (unit number 0).

Now we set unit number to pcic device first, then access to pcic_slots
based on the unit number we've just set.

b72c23d796 There is no atdevbase on the alpha. Hide this case statement on alpha until
the design/implementation is complete.

c0ac0d40f5 o Implement some compatibility functions for NEWCARD compat. This is
incomplete, but will eventually allow the same drivers to function
  with both oldcard and newcard.
o Remove include of opt_bus.h.  It isn't needed and gets in the way of
  module building.
