A scheme to enhance USB-C port policy by dynamically entering optimal USB-C alternate mode with an informed feedback mechanism to OSPM which influences the USB-C port DPM. In some embodiments, when a USB4 device is connected to a port, the scheme parses the alternate modes and power characteristics from the class descriptor information of the enumerated device. In some embodiments, the parsed information is provided as a feedback to the OSPM that instructs the USB-C/PD DPM to enter or switch mode that shall meet the policy criteria of the OS configuration in a dynamic command control from the OS. In some embodiments, the USB-C DPM dynamically chooses to enter an optimal mode based on the power and thermal conditions information available in the embedded controller and indicate the OS about the changes. As such, the OS is aware of the USB operation mode.

Dynamic USB-C mode selection OSPM policy method and apparatus

In one embodiment, an apparatus includes a host controller to implement one or more layers of a Universal Serial Bus (USB)-based protocol to provide an interconnect for a plurality of devices. The host controller is to monitor control plane messages on the interconnect, detect, in the control plane messages, a power state change command for a device coupled to the interconnect, wherein the devices utilizes a tunneled protocol on the interconnect, and modify power distribution for one or more other devices of the interconnect based on detecting the power state change command.

System power management in multi-port I/O hybrid systems

A video processor controlled by a set of non-shadow registers is provided. A list of updates for one or more of the non-shadow registers may be prepared in a memory module. A frame buffer is updated with video data for a display coupled to the video processor. A blanking interval is detected after updating the frame buffer. A direct memory access engine is triggered to transfer the list of updates from the memory module to the non-shadow registers during the blanking interval.
