Why? Once the PCI bus and the devices have been initialised (which
should be a one-off process at boot time), in what way do applications
have to communicate differently? Surely in both cases, internal
registers in the card are mapped to I/O address space, an interrupt
handler is required, and DMA (when used) is just a combination of I/O
register access and interrupt handling. In both cases the application
just needs to know the base I/O address and IRQ used by the card.
