Abstract
A disclosed example involves receiving a message with an action to be performed; determining the message type; and based on the message type, performing an action specified in the message.
Claims21
A storage device comprising instructions that, when executed, cause a processor to at least:
- obtain a first global unique identifier (GUID) via an auxiliary channel during topology discovery, the first GUID corresponding to a first video or audio endpoint;
- obtain a second GUID via the auxiliary channel during the topology discovery, the second GUID corresponding to a second video or audio endpoint;
- and
- determine that the first video or audio endpoint and the second video or audio endpoint are part of a same device when the first GUID corresponding to the first video or audio endpoint matches the second GUID corresponding to the second video or audio endpoint, the same device to store the first GUID in a first GUID register, the first GUID register being one of first DisplayPort configuration data (DPCD) registers, and the same device to store the second GUID in a container descriptor of the second video or audio endpoint.
1 more element
An apparatus comprising:
- a transmitter;
- a receiver;
- memory;
- instructions;
- and
- processor circuitry to execute the instructions to:
- access a first global unique identifier (GUID) obtained via an auxiliary channel during topology discovery, the first GUID corresponding to a first video or audio endpoint;
- access a second GUID obtained via the auxiliary channel during the topology discovery, the second GUID corresponding to a second video or audio endpoint;
- and
- determine that the first video or audio endpoint and the second video or audio endpoint are part of a same device when the first GUID corresponding to the first video or audio endpoint matches the second GUID corresponding to the second video or audio endpoint, the same device to store the first GUID in a first GUID register, the first GUID register corresponding to first DisplayPort configuration data (DPCD) registers, and the same device to store the second GUID from a container descriptor of the second video or audio endpoint.
7 more elements
An apparatus comprising:
- receiver circuitry to obtain a first global unique identifier (GUID) and a second GUID topology discovery via an auxiliary channel, the first GUID corresponding to a first video or audio endpoint, and the second GUID corresponding to a second video or audio endpoint;
- and
- processor circuitry to determine that the first video or audio endpoint and the second video or audio endpoint are part of a same device when the first GUID matches the second GUID, the same device to store the first GUID in a first GUID register, the first GUID register being one of a plurality of DisplayPort configuration data (DPCD) registers, and the same device to store the second GUID in a container descriptor of the second video or audio endpoint.
