Why the disk driver (disk.sys) can not receive a PDO(physical device object) that is created by a class(disk) low filter driver?

Hi,

I refer the following sources in the DDK to develop a disk low filter
driver:
\src\general\toaster\bus
\src\storage\class\disk

I would like to create a PDO in my disk low filter driver, and hope the
disk
driver can see the PDO, but the result is the PDO does not appear in disk
driver.

The following are the main procedure in my disk low filter driver:

call IoCreateDevice(), IoInvalidateDeviceRelations(), then
receive IRP_MJ_PNP.IRP_MN_QUERY_DEVICE_RELATIONS.BusRelati ons,
IRP_MJ_PNP.IRP_MN_START_DEVICE

Any comment for my problem, thanks.

Best Regards,
Peter,

How did you tell the Plug and Play system that the PDO is there and part of
the disk stack. If this is not a PDO filtering an existing PDO you need to
to act like a bus filter and handle IRP_MJ_PNP calls in particular
IRP_MN_QUERY_DEVICE_RELATIONS

Hi,
I call function IoCreateDevice() to create a DO(device object) and call
function
IoInvalidateDeviceRelations() to notify the Plug and Play system. In DDK
source
\src\general\toaster\bus, the bus-enum driver do like these to create a PDO.
And then
I receive the IRP, "IRP_MJ_PNP.IRP_MN_QUERY_DEVICE_RELATIONS.BusRelat ions",
after I handle the IRP, I receive the IRP "IRP_MJ_PNP.IRP_MN_START_DEVICE".

I want to create a PDO, if bus filter driver handles IRP_MJ_PNP calls
in particular
IRP_MN_QUERY_DEVICE_RELATIONS can create a new PDO?

Best Regards,
Peter,

Yes it can.

Hi,
Is it impossible to create a PDO at disk class lower filter? I need a
guide
to create a PDO in my disk lower filter driver.

In my experiences, a PDO is created by a bus driver, if handling
IRP_MJ_PNP "
IRP_MN_QUERY_DEVICE_RELATIONS" in the bus filter driver, it seems only
can monitor or modify the content of the PDO. How the bus filter driver
creates
another PDO?

Peter,

You create a PDO and allocates space for a new list of PDO's then copies the
list comming up from the adapter driver to add the one it wants. If free
the old list that the lower driver allocated. It then has to be careful
for all PNP calls that go to that PDO to act as a bus driver but for all
others act as a filter.

Hi,

As your comments, I trace all communications between disk.sys and Port
driver, the PDO I created in my disk lower filter driver is not passed to
function
"AddDevice" of disk.sys .
Trying to emulate Port driver work in my disk lower filter driver is not
easy
or impossible ?. How I can accomplish the work?
What is the Virtual Storport miniport driver?

Best Regards,
Peter,

Why do you know that AddDevice of disk.sys is not called?
You are trying emulate Port driver work, aren't you. It is not easy.
If your target is Vista SP1 and up you should better use a Virtual
Storport miniport driver.
If you may also trace all communications between disk.sys to Port
Driver to check if you doing everything correctly. You could do it
because you have a lower filter class driver.
Another option is to write your own disk class driver. In this case
you need a bus driver also.

Igor Sharovar

It is not impossible, but does require careful work to handle all the PNP
calls.

If you use a bus driver to handle the real hardware and use KMDF then most
of your PnP and Power issues are resolved. You don't need to handle them in
StorPort as the port driver will just load and unload you when it wants.

Hi,
It seems that the PNP knows what driver creates the PDO.
The PNP seems initiate a PDO in the different way by different drivers :
In my disk low filter driver, it receives only:
IRP_MJ_PNP[IRP_MN_START_DEVICE]
In the bus enum driver which is compiled from DDK sources
"\src\general\toaster\bus", it receives:
IRP_MJ_PNP[IRP_MN_QUERY_ID]
IRP_MJ_PNP[IRP_MN_QUERY_CAPABILITIES]
IRP_MJ_PNP[IRP_MN_QUERY_DEVICE_TEXT]
IRP_MJ_PNP[IRP_MN_QUERY_RESOURCE_REQUIREMENTS]
IRP_MJ_PNP[IRP_MN_QUERY_BUS_INFORMATION]
...

What the PNP will do after it knows a new PDO is created?
Any other info. about device stack and driver stack?

Best Regards,
Peter,
