EvtDeviceDisarmWakeFromSx() is not getting called during wakeup???

NTDEV
1

EvtDeviceDisarmWakeFromSx() is not getting called when the system wakesup from sleep.

What could be the reason? Is it not supposed to get called when the system moves from

Dx to D0 state?

I have not registered any other callbacks with WdfDeviceInitSetPowerPolicyEventCallbacks apart from

EvtDeviceDisarmWakeFromSx().

Though ndistest run on miniport sitting above KMDF-Bus Driver passes all PowerManagement tests in

NDISTEST 6.5.

Thanks,

Perhaps you went into an Sx state that you cannot wake from. Is this on a root enumerated device or a PCI device? Register for EvtDeviceArmWakeFromSx as well and see if that is called. Did you call WdfDeviceAssignSxWakeSettings to enable from sx?

Hi,

No, I dont think it goes in “Sx state that you cannot wake from”. All
Powermanagement tests in ndistest6.5 are passing
peacefully.

Its an enumerated device by our Bus-driver. So I called
WdfDeviceAssignSxWakeSettings for BD that enumerates
the child-device. I register this callback for my child-device.

Will try registering EvtDeviceArmWakeFromSx . and see if it gets called.

Regds,

Just because the NDIS test passed does not mean that you didn’t go into
a power state from which you could not wake the machine.
