Abstract
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.
