Windows WDF Driver Power States

208 views Asked by At

I'm working with WDF. Im reading a driver sample but cannot infer the semantic meaning of:
- WdfPowerDeviceD0
- WdfPowerDeviceD1
- WdfPowerDeviceD2
- WdfPowerDeviceD3
- WdfPowerDeviceD3Final.

Would appreciate any help on the subject.

These are device specific power states. Check ACPI 6.0 spec's section titled "2.3 Device Power State Definitions" Which sample are you looking at ?
