thorpej 01daecba3a Implement pci_decompose_tag(). 1996-12-17 01:55:56 +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.

cgd 79e0a8a2b9 update for addition of a machine-dependent cookie as the first argument
to isa_intr_{,dis}establish().

mycroft 30c174cdcf Use a more standard and more sane error cleanup convention... 1996-03-27 06:49:54 +00:00
cgd da3136aba8 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) deprecate the pci_map_* functions, and provide them only
	    as compatibility interfaces (in pci_compat.c) which will
	    eventually go away, implemented as wrappers around
	    the functions described above.
	(5) make pci functions take as an argument a machine-dependent
	    cookie, to allow more flexibility in implementation.

cgd 0926920201 (1) 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)
(2) 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.)

mycroft 3da4b2a160 The IST_* and IPL_* constants are not bus-specific; don't treat them as such.
