Communication between smbus driver and miniport driver.

WINDBG

Hi All,

How can I send an IRP from SMBus driver to Miniport driver? Is there a way
to share memory between two kernel device drivers?

Thanks,
Vasu

Vasu:
There are a couple of options:

  1. You can use ZwCreateSection(ZwOpenSection) & ZwMapViewOfSection to
    create named memory map in one driver and have miniport driver to open
    it. You also needs to use named sync event or mutex to sync the code.

  2. You can use LPC call.

  3. Obviously, you can roll you own DeviceIO code, is that easier?
