2334e40985 intline == 0 is not a valid intline on 386. See pci_cfgintr() in
sys/i386/pci/pci_cfgreg.c.

This should resolve some cases where adding USB support to the kernel
produced an interrupt storm.

7ba175ac23 Use the pci.c code wherever possible, rather than copying all the pci
code into cardbus and s/pci/cardbus.  This exposes a few pci_*
functions that are now static.

This work is similar to work Justin posted to the mobile list about a
year or two ago, which I have neglected since then.

This is a subset of his current work with the multiple inheritance
newbus architecutre.  When completed, that will eliminate the need for
pci/pci_private.h.

Similar work is needed for the cardbus_cis and pccard_cis code as well.

d0036d6ebc Remove bogus range restrictions that attempted to restrict the range
of I/O in 1.5.  It looks like I got it right only for some of the
cases.  Instead, allow ISA addresses as a special case.  Most PCI
bridges decode this range.  I need to investigate PCI bridges better
to know if this is always true or not, but for now assume that it is
since that seems to be the most common case.

# We need to allocate addresses better for the pccard stuff...

7eea743ef8 Experimental patch to try to properly clip the range of the memory
request to one that's supported by the bridge.  I'm not 100% sure this
is correct, but it makes it easier for the cardbus bridge to allocate
its memory.

Similar code is needed for the I/O range.  Also, I'm not sure if I
should be doing this based on memory or pmemory (but likely should do
it based on some flag that tells us to prefetch or not).

6dc5259a6c Backout previous revision. While it fixed many platforms, it broke
all alphas with devices behind ppb's.  I'm working on a better solution now.

Note that all alphas that use per-platform interrupt mapping are broken
again (as they have been for several months)

d6a516cf80 finally fix intr routing on alphas such as the as500 after months of
breakage:

- call PCIB_ROUTE_INTERRUPT() regardless of how valid the intline looks.
  Some alphas leave garbage in the intline and leave the intr mapping
  to OS platform support routines that map slots/buses to intlines
- Down in the alpha pci code, first try platform.pci_intr_route() and
  if it doesn't exist or returns garbage, just read the intline out of
  config space.

tested on AS500 (garbage in intline) and UP1000 (PC-like, intline is valid)

Note that a nice little hack like the APIC_IO section of pci_cfgregread()
is not workable.  This is because the calling interface for
alpha_pci_route_interrupt() requires us to figure out the bus/slot/etc
from a device_t.  At pci_read_device() time, we don't have a device_t
for the bus/slot/func in question.

8983cfbf27 Next round of PCI subsystem updates:
- Break out the /dev/pci driver into a separate file.
 - Kill the COMPAT_OLDPCI support.
 - Make the EISA bridge attach a bit more like the old code; explicitly
   check for the existence of eisa0/isa0 and only attach if they don't
   already exist.  Only make one bus_generic_attach() pass over the
   bridge, once both busses are attached.  Note that the stupid Intel
   bridge's class is entirely unpredictable.
 - Add prototypes and re-layout the core PCI modules in line with
   current coding standards (not a major whitespace change, just moving
   the module data to the top of the file).
 - Remove redundant type-2 bridge support from the core PCI code; the
   PCI-CardBus code does this itself internally.  Remove the now
   entirely redundant header-class-specific support, as well as the
   secondary and subordinate bus number fields.  These are bridge
   attributes now.
 - Add support for PCI Extended Capabilities.
 - Add support for PCI Power Management.  The interface currently
   allows a driver to query and set the power state of a device.
 - Add helper functions to allow drivers to enable/disable busmastering
   and the decoding of I/O and memory ranges.
 - Use PCI_SLOTMAX and PCI_FUNCMAX rather than magic numbers in some
   places.
 - Make the PCI-PCI bridge code a little more paranoid about valid
   I/O and memory decodes.
 - Add some more PCI register definitions for the command and status
   registers.  Correct another bogus definition for type-1 bridges.

4fa59183f1 - We have access to our own device_t here, so use pci_read_config
rather than finding our parent pcib and using its PCI_READ_CONFIG
   method.

 - Fix the defines for the 32-bit I/O decode registers, and properly
   process the 16-bit versions.  Now we will correctly check that I/O
   resources behind the bridge are going to be decoded.

 - Bring the quirk for the Orion PCI:PCI bridge in here (since it
   seems to want to set the secondary/supplementary bus numbers).

 - Use PCI_SLOTMAX rather than a magic number.

fed8edf563 - Don't return early from the PCI:EISA bridge attachment, or we will lose
the ISA bus.
 - Don't expect that a PCI:ISA bridge will have a correct class value;
   if we're checking PCI IDs, only depend on these.

This should fix the loss of ISA on machines with PCI:EISA bridges like the
AS4100.

bb0d0a8efc Next phase in the PCI subsystem cleanup.
- Move PCI core code to dev/pci.
 - Split bridge code out into separate modules.
 - Remove the descriptive strings from the bridge drivers.  If you
   want to know what a device is, use pciconf.  Add support for
   broadly identifying devices based on class/subclass, and for
   parsing a preloaded device identification database so that if
   you want to waste the memory, you can identify *anything* we know
   about.
 - Remove machine-dependant code from the core PCI code.  APIC interrupt
   mapping is performed by shadowing the intline register in machine-
   dependant code.
 - Bring interrupt routing support to the Alpha
   (although many platforms don't yet support routing or mapping
   interrupts entirely correctly).  This resulted in spamming
   <sys/bus.h> into more places than it really should have gone.
 - Put sys/dev on the kernel/modules include path.  This avoids
   having to change *all* the pci*.h includes.

689634a3ea Convert the pcib_{read,write}_config args from signed to unsigned,

This reduces the likelyhood of overflow when the args are used in
macros on the alpha.  This prevents memory management faults when
probing the pci bus on sables, multias and nonames.
