'RELENG_5_3_0_RELEASE'.

This commit was manufactured to restore the state of the 5.3-RELEASE image.

Move towards isa attachment for pccbb. This is a work in progress, but

2004-08-12T06:50:29+00:00

works well with the pci attachment.

Now that we have the resource allocation code in current, the kludge

2004-05-21T06:10:13+00:00

to try to allocate things on my parent can be taken out.  It duplicates code.

Also, add comment about why the power state stuff is here (type 2
devices don't participate in the power state save/restore due to
larger Bx issues).

Make cbb interrupts MPSAFE:

2003-06-12T03:37:28+00:00

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.

Migrate some common pccard code into exca.

Simplify the power code somewhat (this makes the module about 100

2003-06-07T20:18:45+00:00

bytes smaller).

Add two of three workarounds for interrupt storms for o2micro parts as

2003-06-06T06:00:49+00:00

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.

o Better resume code.  Move the comments around.  Force the socket state to
  be querried.  Ack the interrupts properly.
o Intercept the interrupt requests and keep a list of interrupts to service
  ourselves.  When the card attaches, set its OK bit.  When we get a card
  status change interrupt for that card, clear the OK bit.  Don't call the
  ISR if the OK bit is cleared.  Iwasaki-san and yamamoto-san have both
  sent me patches that fix the same problem this fixes, but at the pccard
  level.
o Try to get the signalling of the thread to actually die.  This might not be
  100% right, but it is less wrong than before.
o Add a SIC next to a TI type that looks like it could be wrong, but isn't.

Rename the pccbb device to cbb.

When we allocate our bus address via the kludge that we have in the

2002-08-10T06:37:32+00:00

code to do it when the bios doesn't do it for us, flag it.  Then, when
we dealloc, do an equal kludge to get rid of the address.  This should
address the can't get IRQ and panic bug in a more graceful way.

# really should write a dealloc routine and just call it instead, since
# this might not fix things in the kldunload case.
