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： Systems, apparatuses and methods may provide for technology that detects a low battery condition in a computing system including an integrated graphics processor and a discrete graphics processor, wherein the low battery condition is detected during a pre-boot stage of the computing system. The technology may also disable a root port associated with the discrete graphics processor in response to the low battery condition, conduct an initialization of an integrated display while the root port is disabled, and enable the root port in response to a successful negotiation of increased power by a verified read write code of an embedded controller of the computing system.

摘要： Embodiments are directed toward a universal serial bus (USB) controller including a USB Type-C port that couples to a USB Type-C link including high speed data lines and an alternate mode function line to carry low power commands related to an alternate mode function. In embodiments, the controller or a processor coupled to the controller monitors the line used by the alternate mode function for the low power commands and provides information about the low power commands to a device policy manager (DPM) to determine a power distribution policy for a plurality of devices coupled to the DPM. In embodiments, the power distribution policy supplements or replaces a low power policy of a device of using a USB-C/Power delivery policy and another device using an alternate mode low power policy. Other embodiments may be described and/or claimed.

摘要： In embodiments, at least one computer-readable medium (CRM) includes a plurality of instructions to cause a computing device, in response to execution of the instructions, to operate a power manager to: receive a request from a first operating system (OS) of a virtualized execution environment (VEE) of the computing device to suspend a first input/output (I/O) device of the computing device. The computing device has a plurality of I/O ports for receiving a plurality of I/O devices including the first I/O device. The plurality of I/O ports are virtualized for a plurality of OSes of the VEE, including the first OS. In response to the receipt, the power manager conditionally suspends the first I/O device if no other guest OS of the VEE is using the first I/O device. Other embodiments are also described and claimed.

摘要： An apparatus is provided, where the apparatus includes a plurality of input/output (I/O) ports and a controller. A first port, a second port, and a third port are to be respectively coupled to a first device with a first class type, a second device with a second class type, and a third device with a third class type. The controller is to determine that individual ones of the first and second devices are to perform asynchronous transfer with the apparatus, and that the third device is to perform a transfer that is different from the asynchronous transfer. The controller is to allocate bandwidth to the first and second I/O ports, based at least in part on the first class type and the second class type. The controller is to ignore the third class type, while allocating bandwidth to the third I/O port.
