register interrupts

Hi all,
Thank you very much in advance.

my PCI device have 7 subsystems. each one have read write and IOCTRL
functionality. 3 of them use interrupts.

therefore I have to write 7 separate drivers for each subsystems.
I do not want to install this drivers. they may be work simultaneously.

I have problem to register interrupts. How should get information to
register interrupts(interrupt vector and level).
(I have to use WDM model )

Are the subsystems independant? I.E. are they seperate functions as defined
by the PCI spec or do they share registers or interrupts? If they are
seperate just write 7 drivers, if the hardware is shared you need to write a
bus driver if you truly want 7 drivers.

Interrupts are provided to you in IRP_MN_START_DEVICE like the other
hardware resources.

I am curious why you state you have to use the WDM model? What OS are you
trying to support that does not support KMDF?

Thanks for the answers.

where can i find a good example for it.

When it is called. Is it call after DriverEntry.

WindowsXP . it is a customer requirement .

Then you do not need a bus driver, just describe the functions as devices.

After DriverEntry and an AddDevice as part of the IRP_MJ_PNP

Is that Windows XP or Windows XP SP2 if the latter KMDF works fine.

In my code says as bellow
pDriverObject->MajorFunction[IRP_MJ_PNP]= PciDrvDispatchPnp;
pDriverObject->MajorFunction[IRP_MJ_CREATE]= create;
pDriverObject->MajorFunction[IRP_MJ_CLOSE]= close;
pDriverObject->MajorFunction[IRP_MJ_READ]= read;
pDriverObject->MajorFunction[IRP_MJ_WRITE]= write;
pDriverObject->MajorFunction[IRP_MJ_DEVICE_CONTROL]= ioControl;
pDriverObject->DriverUnload= unload;
pDriverObject->DriverExtension->AddDevice= PciDrvAddDevice;

then try to open driver using
hdriver = CreateFile(DRIVER_FILE_NAME,
GENERIC_READ | GENERIC_WRITE,
0,
NULL,
OPEN_EXISTING,
FILE_ATTRIBUTE_NORMAL,
NULL);
and start service
but
PciDrvDispatchPnp or PciDrvAddDevice did not call.
what would be the reason. Do i have to write PNP driver.
Is there any method dispatch IRP_MJ_PNP manually.

How did you install the device? You need an INF file that descrives the
particular function you are managing. If you install the driver with
StartService you will get the behavior you described.

Some time it become a stupid question, but i have to ask.
I do not need to install this drivers . because my device have more then one
drivers. Is there any other method to register interrupts. I have three
drivers with interrupts.

You have to install the driver. More importantly the install with an INF
file is the mechanism for associating the driver with the device, without
this you have no way of having the OS call your driver when it finds your
device.

Also, you did not answer does your client require XP prior to SP2? If not
consider KMDF this will be much easier.

Thanks . I got it.
That means i must write to PNP driver and install it.
So can i install more than one driver for one device.

Yes I cannot use KMDF.

You can install one driver per function, you need to have your descriptors
cover the specific device ids from the configuration space for each
function.

I am thankful if you can give me a good site which have examples to get
knowledge about this area.

KMDF works on XP gold or XP SP2, the SP does not matter.
