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.

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.

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.
1996-03-27 04:01:10 +00:00

(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.)
