christos 2d0606e988 remove unused variables 1996-05-03 17:33:49 +00:00
cgd 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.

cgd 72060dc6fa add definitions for the BIST/Header Type/Latency Timer/Cache Line Size
configuration space register, and use it to determine whether or not
a given PCI device uses multiple functions.

thorpej 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.

cgd 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.

cgd 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.)

cgd a38dcb7018 remember the bus_chipset_tag_t given by our parent, and pass it on to
children.

cgd acabb62791 the i386 port no longer attaches isa, eisa, and pci at root. 1996-03-04 03:29:12 +00:00
cgd a4d39f5063 fix uninitialized variable; it shouldn't have been a variable at all.
(when probing to see if a device is there, always probe function 0.)

cgd f1f9317dfb make PCI bus match/attach and sub-device attachment machine-independent. 1996-02-28 01:44:41 +00:00
cgd ae76c070ec oops; forgot this in last commit 1995-06-17 23:06:44 +00:00
cgd bad826164e split single-subdevice lookup & attachment into a subroutine
(pci_attach_subdev()).  remove pciattach() function and the pcicd cfdriver
struct, the former because thre are a lot of attachment actions which really
are machine-dependent (perhaps even "most"), and the latter because now that
both pcimatch() and pciattach() are machine-dependent it's bad style to
declare them here and it gains nothing.

mycroft f8183b2d0e Make a wrapper match function to check the bus and device numbers, rather
than insisting that every driver do it.
