How to add power management function into WFP driver

Question

Hi,

I have wroten a WFP driver, its objective is for capturing connection between outbound packet and process (get process ID and network packet 5 tuples), it works well.

In driver, I simply support power management with following sample codes:

if(IrpStack->MajorFunction ==IRP_MJ_POWER )

{   
    Irp->IoStatus.Status = Status;
    IoCompleteRequest(Irp, IO_NO_INCREMENT);

}

When I tried to pass WHCK test, job 1798(power management support) fails, and I does not konw root reason, please help me, if possible, please give me some sample code snatch.

If you have any question, please tell me here.

Thanks,

Rick Wang

Answer 1

please post the log for the failing job (on the machine under test it will be %WinDir%\System32\Filter.Driver.WindowsFilteringPlatform.ArchitecturalDesign.SupportPowerManagedStates.NTLog

For a sample of how to handle power states, you can look at the WFPSampler:
