Description: |
This function retrieves an AUX channel request issued by the connected DisplayPort source. cmd and address are the command byte and the address in the original request received, respectively (refer to the VESA DisplayPort Standard for more details). When the request is a write, *data fills with the data bytes sent by the source. To support address-only requests, length is the original len byte sent by the source incremented by one. |
