    摘要： 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.

    摘要： Example apparatus disclosed herein compare one or more audio latency characteristics with one or more audio latency requirements in response to detection of an audio silence event, the audio latency characteristic(s) associated with at least one of a hardware layer or a device layer of an audio stack of a compute device, the audio latency requirement(s) associated with an application. Disclosed example apparatus also control a device layer of the audio stack to enter a device layer low power mode in response to a first determination that the audio latency requirement(s) is/are met by the audio latency characteristic(s). Disclosed example apparatus further control a hardware layer of the audio stack to enter a hardware layer low power mode in response to the first determination and a second determination that an operation condition for entry into the hardware layer low power mode is met.

    摘要： A WiFi serial bus (WSB) attribute for use in Wi-Fi Alliance defined point-to-point (P2P) discovery mechanism includes a plurality of fields disposed in the frame. The WiFi serial bus attribute is arranged to provide information in the plurality of fields to support connectivity decisions for a USB device in a point-to-point network using a WSB protocol. The WSB attribute includes WSB architectural element information and information associated with a USB device behind a USB protocol adaptation layer (PAL).

    摘要： In one embodiment, an apparatus includes: a converter to receive and convert single-ended data to differential data, and receive and convert a single-ended clock signal to a differential clock signal; a multiplexer coupled to the converter to receive the differential data and the differential clock signal; and a controller coupled to the multiplexer. In response to an indication that a device coupled to the apparatus is capable of an alternate mode, the controller is to configure the multiplexer to send the differential data on at least one of a plurality of differential pairs of data lanes. Other embodiments are described and claimed.
