Power governance circuitry is provided to control a performance level of a processing unit of a processing platform. The power governance circuitry comprises measurement circuitry to measure a current utilization of the processing unit at a current operating frequency and to determine any change in utilization or power and frequency control circuitry is provided to update the current operating frequency to a new operating frequency by determining a new target quantified power expenditure to be applied in a subsequent processing cycle depending on the determination of any change in utilization or power. A new operating frequency is selected to satisfy the new target quantified power based on a scalability function specifying a variation of a given value of utilization or power with the operating frequency. A processing platform and machine readable instructions are provided to set a new quantified target power of a processing unit.

Power governance of processing unit

Systems and methods for multi-modal user device authentication are disclosed. An example electronic device includes a first sensor, a microphone, a first camera, and a confidence analyzer to authenticate a subject as the authorized user in response to a user presence detection analyzer detecting a presence of the subject and one or more of (a) an audio data analyzer detecting a voice of an authorized user or (b) an image data analyzer detecting a feature of the authorized user. The example electronic device includes a processor to cause the electronic device to move from a first power state to a second power state in response to the confidence analyzer authenticating the user as the authorized user. The electronic device is to consume a greater amount of power in the second power state than the first power state.

Systems and methods for multi-modal user device authentication

Methods and apparatus to operate closed-lid portable computers are disclosed. An example portable computer includes a first display on a lid of the portable computer, the first display to be deactivated when the lid is in a closed position; a second display distinct from the first display, the second display to be visible when the lid is in the closed position; instructions; and processor circuitry to execute the instructions to cause activation of the first display in response to a user interaction with the second display while the lid is in the closed position.

Methods and apparatus to operate closed-lid portable computers

A mechanism where the locked pages are saved and restored by a hardware accelerator which is transparent to the OS. Prior to standby entry, the OS puts all DMA capable devices in the lowest-powered device low-power state after disabling bus mastering. The OS flushes all pageable memory to an NVM (in segments that are kept in self-refresh) and provides a list of pinned and locked pages in the DRAM to a power management controller (p-unit). The p-unit checks for all Bus Mastering DMA to be turned off and checks if a next OS timer wake event (TNTE) is greater than a threshold, to decide whether to enable or disable PASR or MPSM in Standby. If the conditions are met, the p-unit triggers a hardware accelerator to consolidate the pinned and locked pages in the DRAM to certain segment(s) of the DRAM during standby states, making it transparent to the OS.

Memory power management method and apparatus

Techniques for controlling input/output (I/O) power usage are disclosed. In the illustrative embodiment, a power policy engine of a compute device monitors power usage, I/O data transfer rates, and temperature and determines when there should be a change in an I/O power setting. The I/O data transfer requires that the data be handled properly, causing the compute device to expend power on the I/O data transfer. The power policy engine may instruct a device driver, such as a driver of an I/O device, to change a data transfer rate of the I/O device, reducing the power the compute device spends handling I/O.

Technologies for dynamic input/output data transfer rate scaling based on power policy engine

Methods and apparatus to operate closed-lid portable computers are disclosed. An example portable compute device includes: a microphone; a speaker; a first camera to face a first direction; and a second camera to face a second direction, the second direction opposite the first direction. The compute device further includes communications circuitry; a first display; a second display separate from the first display; and a hinge to enable the first display to rotate relative to the second display between an open position and a closed position. At least a portion of the second display is capable of being visible when the first display is rotated about the hinge to the closed position. The portion of the second display is multiple times longer in a third direction than in a fourth direction perpendicular to the third direction, the third direction extending parallel to an axis of rotation of the hinge.

A power delivery system of a computing system that is on alternating current (AC) power limits software administrative tasks to a system-controlled and tunable broadcast window. This window limitation allows a computing system to enter and stay in low-power states without variable disturbances from administrative functions that can be relegated to the window. For example, maintenance is restricted until the computing system broadcasts a notification. Legacy software and devices that do not understand these notifications can be told the AC power is not present nominally, and then be notified of AC power presence during maintenance intervals.

Systems, methods and devices for standby power savings

Methods and apparatus to operate closed-lid portable computers are disclosed. An example apparatus includes a camera input analyzer to analyze image data captured by a world facing camera on a portable computer when a lid of the portable computer is in a closed position. The world facing camera is on a first side of the lid. The portable computer includes a primary display on a second side of the lid opposite the first side. The example apparatus further includes a secondary display controller to render content via a secondary display of the portable computer in response to the analysis of the image data. The secondary display controller is to render the content on the secondary display while the lid of the portable computer is in the closed position and the primary display is turned off.

Various embodiments are generally directed to an apparatus, method and other techniques for receiving information to invoke a transition from a first operating system to a second operating system, copying a system context for the second operating system from a location of a non-volatile memory to a volatile memory, the location associated with the second operating system and transitioning from the first operating system to the second operating system using the system context for the second operating system.

Techniques for switching between operating systems

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.

Flexible multiport USB type-C power management

Embodiments are generally directed to sharing of environmental data for client device usage. An embodiment of a client device includes a processor; an environmental sensor to sense an environmental condition, an output of the sensor being a local environmental sensor value; and a wireless receiver to receive environmental data for a certain proximity area from a second client device according to an environmental data sharing protocol via a wireless network. The environmental data sharing protocol allows receipt of the environmental data without requiring pairing, bonding, or other relationship of client devices.
