sys/pci pci.c pci_compat.c pcivar.h
Log:
On the new Meteor cards, the Philips SAA 7116 is connected to the PCI bus
via an IBM PCI-PCI bridge (82351 or 82352 or 82353)
The driver must identify if it is on a secondary PCI bus, which is
created via the IBM PCI-PCI bridge. If it is, then it must initialise
the IBM PCI-PCI bridge correctly.
To do this, the following new functions are added.
Because they use the pcici_t tag, they are considered 2.2 compatibility APIs
pcici_t * pci_get_parent_from_tag(pcici_t tag);
int pci_get_bus_from_tag(pcici_t tag);
(The _from_tag suffix is used to prevent clashes with similarly named
newbus PCI API functions)
