Privyet!
Hello,
Thank you for answer. The reason I am asking is
that for
IRP_MN_QUERY_DEVICE_RELATIONS
IRP_MN_QUERY_QUERY_RELATIONS
IRP_MN_QUERY_CHARACTERISTICS
I am just passing down to the underlying bus driver.
I.e. I don’t do anything with these IRPs in my
function driver. Now I am trying run HCT (WHQL) and I
am getting failure on “device path test”. The test log
doesn’t help at all. Some I am thinking maybe I am not
handling these IRPs correctly, i.e. I should not only
pass to bus driver, but also do something in my
driver.
In driver books it doesn’t say much about these IRPs.
I “deregistered” my DeviceIoControl dispatch function
to narrow done problem … that is why I suspect a PnP
IRP problem.
BTW, I find WHQL very frustrating because logs do not
help!
Regards, Vasili

As I understand it, the HCT logs are to report the pass/fail results of the
tests. As such, they are not dumps designed to help you debug your code.
I would strongly suggest you try running DriverVerifier, PreFast, DC2, and
other such DDK development tools to identify and troubleshoot where your
driver is failing and why. Also, please do so with a debugger attached to
the system under test so that you can break on the point of failure.
