- Virtio GPU Device specific type and macro definitions.
-
- At the time of this writing, the Virtio 1.0 specification has not
- incorporated the GPU device yet. The following work-in-progress specification
- is used as basis for the implementation:
-
- - https://lists.oasis-open.org/archives/virtio-dev/201605/msg00002.html
- - https://www.kraxel.org/virtio/
-
- This header file is minimal, and only defines the types and macros that are
- necessary for the OvmfPkg implementation.
