5.2.1. Platform Device Classes

The OPAE Platform provides for AFU integration into the stack through several device classes. Each device class offers one or more port interfaces, each of which have properties of their own. AFUs request a specific device interface and properties from the PIM. The PIM implements the requested interfaces and properties in a platform shim that translates hardware platform-specific device interfaces to the OPAE Platform’s generic device interfaces used by the AFU.
