  • Publication number: 20230096774
    Abstract: Buses such as USB4 or Thunderbolt 4 buses may allow for device combinations that actually cannot be accommodated on the bus. A monitoring component, e.g., software and/or hardware component, such as an Operating System (OS) policy manager, may monitor a bus for events identifying changes to devices on the bus. The monitoring component may influence mode changes to hardware/software, such as to the USB configuration, device driver settings, attached device settings, and/or settings for devices attaching to the bus. Influenced changes facilitate accommodating changes to the devices attached to the bus. For example, if a display is attached and it would exceed available bus bandwidth, cause an excess system load, or cause some other problem, rather than fail to enumerate the display, instead hardware and/or software associated with the bus may be influenced to result in a resolution reduction for the display to accommodate it attaching to the bus.

  • Publication number: 20230096631
    Abstract: Universal Serial Bus (USB) Power Delivery is augmented by allowing devices that attach to the USB to include and/or have access to an enhanced device policy manager (eDPM) so that device information such as status, state, or requirements, such as power requirements, may be at least be shared by the eDPMs between, for example, a host device on the bus, a secondary device providing power to devices on the bus, and a new device attaching to the bus. Sharing device information facilitates the host having contextual awareness for the attaching device and assists with determining whether the attaching device may be enumerated on the bus. If not, such as due to insufficient power available from the secondary device, the host and/or secondary device may seek to influence bus devices to change an operating mode to accommodate the attaching device.

  • Publication number: 20220197842
    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.

  • Publication number: 20220091853
    Abstract: A data processing system comprises a processing core to execute a basic input/output system (BIOS) as part of a boot process. The data processing system also comprises static random-access memory (SRAM) in communication with the processing core. The data processing system also comprises a pre-BIOS component in communication with the SRAM. The pre-BIOS component is configured to execute a pre-BIOS block of firmware before the processing core begins executing the BIOS. The pre-BIOS block, when executed by the pre-BIOS component, causes the pre-BIOS component to (a) initialize the pre-BIOS component, (b) measure an amount of time taken to initialize the pre-BIOS component, and (c) save the measured amount of time to the SRAM as a pre-BIOS boot-time record. Other embodiments are described and claimed.
