Attaching function drivers to the bus

Hi,
I’m developing a simple WDM function driver. Whether it is necessary to attach this function driver to a specific bus driver or else the Io manager takes care of those attach process.

Thanks

You attach to a specific physical device object if you are dealing with
hardware, drivers do not attach to drivers. This and your follow on
question should be in NTDEV not this group which is on file systems.

And the reason why you have rejected doing this in WDF/KMDF?
