I have a general question about a PCI-to-PCI bridge.
If the device has a positive decoder and receives an address in the
range of the addresses it should respond. Then it claims the address
and forwards it to the secondary interface. Now suppose no target on
the secondary interface claims the transaction and master-abort
happens for the second interface. What will happen to the primary
Why PCI specifications do not explain the connection between the state
machines of the primary and secondary interfaces?
