-Abstract:
-
- This sample ASL file describes a sample GPIO device and a sample peripheral
- device which consumes IO and interrupt resources from the GPIO device. Please
- note that:
-
- 1. The memory and IO descriptor under the GPIO device are simply examples of
- what can be described. They are commented out to illustrate this point. Actual
- values will vary according to the platform specifications (e.g. GIC and memory)
-
- 2. The sample ASL DSDT definition block defines only the components relevant
- to demonstrate GPIO IO and interrupt resource usage. Rest of the DSDT will vary
- according to platform specifications.
-
- 3. The PNP IDs for the GPIO and peripheral device are for demonstration purposes
- only. Actual values need to reflect those chosen for the actual GPIO or
- peripheral device.

- If the interface requested is IUnknown it references the object and

-
- This allows other methods to convert a CUnknown pointer into an IUnknown
