Abstract: In an example, a method includes adding a first request from a first requestor to a queue for a shared resource, where the first request has a first priority. The method includes providing the first request to the shared resource from the queue. The method includes processing the first request at the shared resource. The method includes adding a second request from a second requestor to the queue for the shared resource, where the second request has a second priority that is higher than the first priority. The method includes preempting the processing of the first request and notifying the first requestor of the preemption, where notifying the first requestor of the preemption includes providing the first requestor with a duration of availability for the shared resource. The method includes providing the second request to the shared resource from the queue and processing the second request at the shared resource.

Abstract: A method includes generating, by a control unit of a first device, a handshaking signal to be transmitted to a second device via a second channel. The method further includes based on the handshaking signal being acknowledged by the second device, configuring, by the control unit, the second channel to communicate non-display data and configuring a first channel connecting the first device to the second device to selectively communicate either display data or non-display data; and based on the handshaking signal being not acknowledged by the second device, configuring, by the control unit, the first channel to communicate display data.
