Hello everybody,
I have a question regarding the order of loading function drivers in WDM.
I have two function drivers F1 & F2. My requirement is F1 should load first.
then F1 should load F2 based on some conditions.
first question:
can a function driver load another function driver with the help of
registry/
INF files?
if yes, suppose F1 loads F2, then will the device stack look like (a) or
(b)???
What should I do to make it to look like (b) if I wanted to?
(a) -------------
(a) -------------
The reason I want F1 to lie above F2 is because the interaction with the
above application
layer happens through F1 always. ie. F1 only understands commands translated
from above layers and calls appropriate functionalities in F2. But I need F1
to load first and then F2.
Hope my problem is clear…
Eagerly awaiting a reply,
Venky

Load both drivers in any case, register a device interface in F2 and device
interface arrival callback in F1.

Hi All,
Max, Can you please explain how to do that ?
I have the similar problem, I need to layer my drv over some other drv but I
have no idea as to how I should install my drv in order for it to get
layered exectly above or below some system driver.
In general, I understand that PNP looks for a suitable drv in the registery
when it receives a request from a bus driver. But I need to do it with the
serial bus which has no bus driver.
Thanks for any help.
Regards,
Stas Desyatnikov,
Powernet.

Look for “UpperFilters” in msport.inf and topics below about it.
