route interrupts if the child bus is described in the PCIBIOS interrupt routing table. For child busses that are in the routing table, they do not necessarily use a 'swizzle' on their pins on the parent bus to route interrupts for child devices. If the child bus is an embedded device then the pins on the child devices can be (and usually are) directly connected either to a PIC or to a Interrupt Router. This fixes PCIBIOS interrupt routing across PCI-PCI bridges for embedded devices. |
