a49ed2a673 On some laptops, under very high loads, the socket event register read
in the ISR doesn't read the actual socket event register, but instead
reads garbage (usually 0xffffffff, but other times other things).
This totally violates the PCI spec, but happens rarely enough that a
workaround is in order.  This adds one test when we have a real
interrupt to service (which is very rare), and doesn't affect the
usualy 'nothing to see here' case at all.

Problem reported by many, but sam@ gave me this workaround after
diagnosing the problem.

1ab7d4c93d For each of the voltages that a card might support, make sure that the
socket also supports the voltage.  Some XV cards have appeared on the
scene (or cards that report they support XV), and in older machines
that have sockets that do not support XV, we were bogusly trying to
power them at XV rather than at 3.3V.  Now, power up the card at the
lowest voltage supported by both the card and the socket.

3ac604874c Simplify the opening of the resources for cardbus cards. Before we'd
try very hard to be perfect.  However, these attempts broke down when
there were large numbers of resources.  We'd not be able to map them all.

Instead, accept that we might pass more range to thse subbus than
might be optimal be able to compute.  However, there's little harm in
this and it allows us to pass greater resources through.

# it has been suggested that we allocate a fixed amount of resources
# on attach and give it out upon request.  This might not be a bad idea...

o Rather than just try to turn off EXCA_INTR_RESET, set the entire register

o Move attempted clearing of the output enable (EXCA_PWRCTL_OE) back to

b32757b431 o The ricoh bridge needs us to turn off the function interrupts for
16-bit cards when we're powering them up.  Other bridges may have
  similar issues, so we do this for all of them by setting the
  interrupt in the PCIC register 3 to be 0 (done always anyway)
  and turning on the bit in the bridge control register to route these
  interrupts via the ISA bus (or via the interrupt configured in the
  PCIC register 3).  '0' means disable completely.  There's a small
  chance this may interfere with the o2micro power hacks, but I'll
  wait for reports to come in from o2micro users.
o Expand some of the comments about why we do certain things.

# this gets rid of the interrupt storm warnings on my 505TS.  I think
# that we may need to do something similar on suspend, but I'm unsure
# since I don't have a laptop that supports suspened/resume with a
# ricoh chipset in it.

85ef2343c4 The CD interrupt should only be enabled after we've initialized the
card.  Mask it while we're doing power things, as the PC Card standard
suggests.  Also, poll the POWER_CYCLE bit 10x a second as well as
providing a timeout for power cycle interrupt to happen.

The Ricoh '475 that I have doesn't seem to generate an interrupt for
power at the present time, so the polling is necessary for reasons as
yet unknown.  This results in an interrupt storm warning that I'm
still trying to quantify (the o2micro trick doesn't work to mitigate
this storm).  At the very least, this should help those users that
lost pccards on boot with the prior rev of this code.  My VAIO
PCG-505TS is now happier, but more investigation is necessary.

fd4e475233 Omnibus power and interrupt fixes:
o Don't busy wait on powerup.  Instead, use the power up interrupt to wait
  for the card to power up.  Don't wait when we're turning the card off,
  since no interrupt happens in that case.
o Convert many of the long DELAYs to tsleeps.  We do not run before
  the timer have stared, so DELAY isn't necessary.  More DELAYs can likely
  be eliminated in the future.
o When powering up the card, don't do anything if the card is already
  powered up (before we'd power cycle it).  This means that for most
  cards we power them up once and then never change the power.
o On card eject, mask (by clearing) the CD bit.  Before we set it, which
  was wrong.  We don't want to see any CD events past the first one since
  they need to be debounced.

With these changes, I can insert/eject 16bit cards without glitching xmms'
sound output.  Something very important to the development of better pccard
drivers :-)

6c92cac930 Start programming the bus numbers for the pci<->cardbus. When the
secondary bus is 0, we program the primary bus, the secondary bus and
the suborindate bus.  This isn't ideal, since we start at parent_bus +
1 and store this in a static.

Ideally, we'd walk the tree and assign bus numbers.  However, that's
harder to accomplish without some help from the bus layer which we're
not planning on doing that until 6.

This fixes my CardBus problems on my Sony PCG-Z1WA, and might fix the
Dells that have had problems.

cbb_child_present was backwards.  However, typical usage in the tree
would cause it to do the right thing because the card really wasn't
there the OK flag would be turned on.

Also, assume that if any of these bits are turned on we don't have a
card, rather than requiring both of them in the suspend/resume

2724f3214d Some bridges, like o2 micro and maybe ricoh, have some issues between
the time the card is inserted and the time that the card is
configured.  This can lead to interrupt storms.  The O2Micro suggested
workaround is to route the card function interrupt to IRQ1.  It
appears from my testing that this is an acceptable workaround for most
chipsets (there's still some issue with the ricoh chipset).

Also, only look at the NOT_A_CARD bit when the bridge tells us there's
a card present.  At least one test caused this to be true after the
card was removed, but the author couldn't recreate it with the
workaround in place.  The change is more conservative than the
previous code, but still has the work around that wasn't present in
the older code.

fda5b6124b Add code to cope more with strange conditions after careful study of
the standard.

1) When the bridge tells us that we have a card that isn't recognized, we
   use the force register to force the CV_TEST to run.  This test causes the
   bridge to re-evaluate the card.  Once this re-evaluation process happens,
   we get a new interrupt that may say it is ready to process.  We try this up
   to 20 times.  Tests have shown that this appears to correctly reset the
   'Unknown card type' problem that I saw on my Sony PCG-505TS.
2) Take a page from OLDCARD and always read the CSC register in the ISR.
   Some TI (and it seems maybe Ricoh) chipsets require this to behave
   properly.  This work around appears to work due to some power management
   protocols that were improperly implemented.  Maybe it can be removed when
   this driver supports the full PME# protocol described in the standards.
3) Minor additional debug printf when debugging is enabled.
4) Minor additional commentary for things that are obvious only after study.

# I'm committing this from my Sony PCG-505TS using shared PCI interrupts
# and NEWCARD, but there are some issues with the Ricoh bridge still, but
# at least now I can boot with the card inserted and have it work.

BURN_BRIDGES option was invented for.  Mark all of them as
BURN_BRIDGES.  As soon as I have the powerstate stuff properly
integrated into the pci bus code, I intend to remove all these
workarounds.

de5059db1c Make cbb interrupts MPSAFE:
o Register ISR INTR_MPSAFE.
o Loop on KTHREAD_DONE == 0 in the thread.
o Safe the INTR_MPSAFE flag for client drivers (don't know if there are any
  CardBus/PCI drivers that are INTR_MPSAFE)
o Read status after acquiring mtx_lock(Giant) rather than before so that we
  catch state changes that happen while Giant is being acquired.
o Turn off the CD bit when we see a CD interrupt, and turn it back on after
  we've attached/detached the card.
o On suspend, actually set the CBB_SOCKET_MASK to zero rather than oring
  in '0' to turn it off on suspend.
o If the ISR that's registerd is MPSAFE, don't acquire Giant around call to
  client ISR.
o Fix comments to reflect these changes.

e4e7b5bc54 Add two of three workarounds for interrupt storms for o2micro parts as
obtained from o2micro.  These should only be needed for 'older'
o2micro bridges (anything before the 7xxx series of bridges), but will
work with the new bridges.

# I don't plan on porting it to oldcard, but will happily commit to
# oldcard if someone else needs them.

9713a7922e MFp4: Massively unbreak module loading/unloading:
o Only complain about detached children that aren't pccard/cardbus.
o Don't NULL out the pccarddev and cbdev devices.  detach just
  disassociates the device and driver.  It doesn't delete the child.
o on driver added, just probe_and_attach the children.  If there's
  any children attached, wakeup the device add/delete thread.
o wakeup the add/delete thread with the correct cv_signal() rather
  than the bogus wakeup(sc).  It used to be that we did a tsleep on
  sc in this thread, but switched to the more reliable cv stuff a while
  ago w/o changing this.
o Remove bogus checks when reallocating memory for the registers.  They
  weren't needed and turned out to be completely bogus.

This lets me load/unload pccard with a pccard in a slot and have the
child correctly detach/attach.  This should help people that have wi
in their kernel, but that kldload cbb and pccard, for example.
