摘要： Techniques are provided for managing power delivery to multiple universal serial bus (USB) type-C ports of a desktop computer system. In an example, a method can include providing a first power level to a USB power delivery controller during a non-sleep mode operation of the desktop computer, and providing a second power level to the USB power delivery controller when the computer is in a sleep mode, the second power level configured to provide default charge power to a connected device when the computer is in the sleep mode.

摘要： Various techniques for enabling the control and monitoring of a USB device mode controller to a USB-C connector, for the performance of a USB device mode data connection, are disclosed herein. In an example, a computing system that includes multiple USB-C connectors but a single USB device mode controller may manage the mapping of the controller to a particular connector, through operations that identify the mapping and the characteristics of the connector, process a request to change the mapping of the device mode controller, and perform the change to the mapping of the device mode controller. Such a change may include a disconnection or reassignment of a particular USB-C connector to the controller. Further examples to determine the availability of a USB device mode controller, and respond to a scenario where the USB device mode controller is not available, are also disclosed.

摘要： Technologies for pre-memory phase initialization include a computing device having a processor with a cache memory. The computing device may determine whether a temporary memory different from the cache memory of the processor is present for temporary memory access prior to initialization of a main memory of the computing device. In response to determining that temporary memory is present, a portion of the basic input/output instructions may be copied from a non-volatile memory of the computing device to the temporary memory for execution prior to initialization of the main memory. The computing device may also initialize a portion of the cache memory of the processor as Cache as RAM for temporary memory access prior to initialization of the main memory in response to determining that temporary memory is not present. After initialization, the main memory may be configured for subsequent memory access. Other embodiments are described and claimed.
