In the LinuxBIOS-AMD64 document the author explains the "pci" keyword
The first occurrence of the pci keyword tells
LinuxBIOS where the
bridge device start,
relative to PCI configuration space used by the
following occurences of
the pci keyword describe the provided devices.
then gives an example
northbridge amd/amdk8 "mc1"
I'm not clear why the example repeate "pci 0:19.0" three times?
I noticed in chip.c the chip_enumerate() function checks the same path
identical_paths = (i > 0) &&
(path_eq(&chip->path[i - 1].path,
but I can't find out the real intent.
Another question maybe related to the former one is, in "device" structure
what does the "link[MAX_LINKS]" and "links" member describe?
Does "link[MAX_LINKS]" describes the secondary or subordinate bus of a
Why MAX_LINKS is defined to 3?
Thanks in advance.
