Detailed Description

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.
