nathanw 788ff053de Fix up support for PCI attachments of pcic devices on i386 in general, 
and the Cirrus Logic CL-PD6729 in particular.

From danw@mit.edu in PR port-i386/6436.

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

enami c8a28ce872 Cosmetic change; use tab for basic indentation rather than four space. 1998-10-26 03:43:52 +00:00
drochner ff455e77b6 Match pchb by class/subclass, like pcib. 
Add a note about this strange Pequr host bridge in Compaq machines.

thorpej 67b94a13ed Add the Intel 82443BX PCI host bus adapter. From Soren S. Jorvang, PR #6250. 1998-10-08 20:04:32 +00:00
drochner 06753678d5 Remove the chips which are known to identify properly out of the 
old "match" function - more or less for documentation.
Proposed by "Soren S. Jorvang" <soren@t.dk>.

drochner 1d34097b60 Take the Intel SIO into the special case list - it identifies itself 
as "prehistoric". From John Kohl.

drochner 103b7e7b17 The Intel 82371MX identifies itself erroneously as a miscellaneous 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)

drochner d1da31d671 redo the PCI configuration mode detection - should make some less 
standard compliant PCI chipsets work (Compaq, Connectix emulated Triton)
fix the bug reported in PR port-i386/5727 (soda@sra.co.jp)

thorpej c099eb3a4a Add a function, pci_bus_flags(), that determines which flags (for memory 
and i/o enabled) should be passed to the primary PCI bus's autconfiguration
node.  Use this function to detect broken PCI-Host bridges, which have
problems with memory-mapped access.  Add the SIS 85C496 to this list.

thorpej 5e447974cb Add a comment about why the bus dma tag is not provided to the child 
bus attaching to the bridge.

thorpej 2b8a15aed4 Add a comment about why the bus dma tag is not forwarded from parent 
to child if an auxillary PCI bus is attached to the bridge.  Also,
remove an extra ';'.

jtk 86bf57701c add support for dual PCI bus Intel host/PCI bridge. Thanks to Chris Demetriou for his assistance in educating me about the vagaries of PCI and its configuration model. 1997-05-13 22:47:30 +00:00

thorpej 35a40fda4b Implement a simple generic PCI-ISA bridge driver. This driver exists 
primarily to nicely print version information about your PCI chipset
(try with "options PCIVERBOSE").  Eventually, it may be used to
enable/disable features/bugs of a given PCI chipset.  In addition, this
driver uses the PCI-ISA bridge callback mechanism to logically attach the
ISA bus to the PCI-ISA bridge.

thorpej 30612943e3 Implement a simple generic PCI-Host bridge driver. At the moment, this 
driver is a place-holder, which will nicely print version information
about your PCI chipset (try with "options PCIVERBOSE").  Eventually,
this can be used to enable/disable features/bugs of individual PCI
chipsets.

fvdl 753949629e Make this compile again if PCI_CONF_MODE is defined (unused label). 1996-10-24 12:32:29 +00:00
thorpej 16c4c5af26 New bus.h implementation/interface: 
- No more distinction between i/o-mapped and memory-mapped
	  devices.  It's all "bus space" now, and space tags
	  differentiate the space with finer grain than the
	  bus chipset tag.
	- Add memory barrier methods.
	- Implement space alloc/free methods.
	- Implement region read/write methods (like memcpy to/from
	  bus space).
This interface provides a better abstraction for dealing with
machine-independent chipset drivers.
