uch 46fb1c9fce initialize pciirq. 1999-12-13 15:42:05 +00:00
thorpej 2128a07943 Put an interrupt-safe mutex around PCI configuration space access. 1999-12-11 20:48:25 +00:00
thorpej 7f28924acc If we see a bogus $PIR table entry, just ignore it. The MPIIX has 
entries for the IRQs used by the IDE controller, which aren't really
PCI IRQs (they're ISA compat IRQs), and thus have link values that
don't make a lot of sense.

thorpej 0d79886ad5 Fix up the PCI bus numbering after fixing up interrupts. 1999-11-17 07:33:41 +00:00
thorpej f4b4d4508a Code from UCHIYAMA Yasushi's PCI BIOS patches to renumber the PCI 
busses.

thorpej d6d9fbe240 Interrupt router drivers from UCHIYAMA Yasushi's PCI BIOS patches,

thorpej 2026e5f71b PCI interrupt routing fixup code, from UCHIYAMA Yasushi's PCI BIOS 
patches, cleaned up and heavily reworked by me.  Basic algorithm is
the same, although the code structure is now quite different.

Main differences:
- Initialization path is totally different.
- We use the `compat router' information, if present, to determine which
  PCI ICU driver we should use.
- Fixup configuration headers on devices not on bus 0.

thorpej e345f0f17c Basic interface to the PCI BIOS and PCI Interrupt Routing table, separated 
out from UCHIYAMA Yasushi's PCI BIOS patches, and fairly heavily reworked
by me.

Main differences:
- Only use the PCI BIOS to get the config mechanism and interrupt routing
  info for now.  No need to use the BIOS for PCI config access right now,
  since the old mechanism works fine, and this keeps the code smaller.
- PCI BIOS initialization code path is much different.
- Always use the $PIR table if it exists, and only fallback to the
  PCI BIOS 2.1 GetInterruptRouting call if it's not there.

This module does not include any of the fixup code; that is coming
in separate commits.

enami 92d5be6614 Explicitly test Intel 82371AB PCI-ISA bridge since *some* of them 
identify themselves as miscellaneous bridge rather than isa bridge.

drochner 026fbbe2db Match PCI-ISA bridges on class/subclass instead of vendor/device. 
2 reasons:
-no need to keep a list of all known parts
-there is at least 1 bridge (ACC micro 2051) which reports the same
 device ID for its various subfunctions; this would require an additional
 check in the match function
(keep the old list inside #if 0 in case one of the historical bridges
doesn't report the right class/subclass - I can't check them all)

problems with memory-mapped access.  Add the SIS 85C496 to this list.
