Hello,
We are developing a multifunction PCI device, and we have a question
concerning the proper way to identify each function in the device.
Should we use a different Device ID for each function or is it
sufficient to just use a different class code for each function? We
are assuming that it is only necessary to use a different class code
for each function (if it is a different function) and that the Device
Id is used to indicate the device as a whole and not the individual
functions.
