SVN rev 191799 on 2009-05-04 21:04:29Z by jhb
MFC: Expand the support for PCI-e memory mapped configuration space access.
Note that unlike in HEAD, this defaults to off and must be explicitly
enabled by setting the loader tunable hw.pci.mcfg=1.
- Add support for the Intel 915GM chipsets by reading the BAR.
- Add parsing of the ACPI MCFG table to discover memory mapped configuration
access on modern machines.
- Port the memory mapped config acess to amd64. On amd64 it uses the direct
map.
- For config requests to busses not listed in ACPI's min/max valid buses,
fall back to using type #1 configuration access instead.
- Add a workaround for some K8 chipsets that do not expose all devices on
bus 0 via MCFG and fall back to type #1 for those devices instead.
