How to use IoConnectInterrupt to register IRQ 14 or 15?

[Kai Lidda]

Dear all:

How to use IoConnectInterrupt to register IRQ 14/15?

Because IoConnectInterrupt need the translated interrupt vector form
PnP_Start_Device, i need to know how to translate the IRQ 14/15.

please, I have no a normal method for this question, do any ideal to handle
this question?

For what?

The normal way is to call IoConnectInterrupt in the MN_START_DEVICE path with
the translated vector passed in the IRP.

hard coding a specific irq is not a great idea. if the irq is not assigned
to your driver in start device, it is not for you to use.

For example: Intel IDE or SATA Control

They can set their PCI Device to use IRQ 14/15 or INTA, when booting.

So, windows driver can handle it.

If set to INTA, the MN_START_DEVICE can have the translated vector for INTA.
If set to IRQ14/15, the resouces only have base address, not have interrupt.

so, i dont know how to handle a hard code IRQ.

They set this in BIOS, and then Windows borrows these BIOS settings by
IRP_MN_QUERY_RESOURCES.

I cannot understand why you ever need a hardcoded IRQ. Just use the IRQ which
PnP gives you, this is simple.
