197d80c63a update these so they compile whether or not __BROKEN_INDIRECT_CONFIG
is defined.

546c8abcee 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.

2a73ef60b7 change cfprint_t type definition to take a const char *, rather than
a char *, because that's what was really intended, and because
if the print function modifies the string, various things could become
unhappy (so the string should _not_ be modified).

87328287b7 modify these to provide a new, better-specified PCI interface
(soon to be documented on mailing lists; eventually in section 9 manual
pages), most importantly:
	(1) support interrupt pin swizzling on non-i386 systems with
	    PCI-PCI bridges (per PPB spec; done, but meaningless, on i386).
	(2) provide pci_{io,mem}_find(), to determine what I/O or memory
	    space is described by a given PCI configuration space
	    mapping register.
	(3) provide pci_intr_map(), pci_intr_string(), and
	    pci_intr_{,dis}establish() to manipulate and print info about
	    PCI interrupts.
	(4) make pci functions take as an argument a machine-dependent
	    cookie, to allow more flexibility in implementation.

de7c200585 New device attachment scheme:
- split softc size and match/attach out from cfdriver into
	  a new struct cfattach.

	- new "attach" directive for files.*.  May specify the name of
	  the cfattach structure, so that devices may be easily attached
	  to parents with different autoconfiguration semantics.

ba6d1cb2dd These devices don't actually need softc's that are supersets of 'struct
device.'  No point in adding that complexity + space if they're not needed,
so axe them.

7fda077700 (1) provide #defines for cf_loc[] entries for devices that attach to
pcibus and pci.
(2) remove the #ifdef i386 from pci.c, and provide a machine-dependent
    hook (pci_md_attach_hook()) to do any machine-dependent attachment
    gunk, e.g. on the i386 printing out the configuration mode (if bus 0)
(3) don't pass max device number for a given bus in, use
    PCI_MAX_DEVICE_NUMBER, which can be defined on a per-machine basis.
    (defaults to 32.  on i386, it's 32 if pci conf mode == 1, 16 if 2.)

272d9f69d2 fix aux argument to config_found() for secondary bus. 1996-03-04 17:02:46 +00:00

47e551efff Preliminary support for PCI-PCI bridges. Recognize a PCI-PCI bridge
and attach the secondary pci bus as a 'pci' device.  Note that this support
is incomplete and will not yet work for ports other than that i386.  (The
i386 can rely on the PCI interrupt 'line' information to determine
interrupt mapping, which is not necessarily possible on other systems.)
