driver will populate the registry
with info about bus/device/function, INT, IRQ, BAR for the devices on the
bus if you provide a template registry.
structure for your device. You can write a simple stream interface driver:
the device manager will pass you a registry
key by which you can access the info I listed above. Then you can use
HalGetBusDataByOffset / HalSetBusDataByOffset
to access PCI configuration space for your device. you can take a look at
