Abstract: 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.

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.

Abstract: Systems, apparatuses and methods may provide for technology that initiates a boot of a computing system containing an embedded controller while the computing system is in a low power mode, conducts a verification that code to perform the boot is uncorrupted, and negotiates an increased power delivery with a source device connected to the computing system if the verification is successful.
