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 ?

  • Im looking at the PCMIA Smart Card Example. Getting a wiff at some Driver Code, eventually I'll have to develop one, but it is quite hard to straighten out. – Fernando Pérez Jan 30 '17 at 17:01
