A data scaling module for USB4 that embodies display driver (DD) and connection manager (CM) operations. Periodic and aperiodic transfer requests are monitored. The periodic BW activity on periodic peripherals, such as display panels (DPs) is monitored, and determinations as to reduced periodic activity on a DP are made. Responsive to receiving a high aperiodic bandwidth request, the original refresh rate for the DP is reduced. The newly freed USB4 BW is provided for the aperiodic task. At completion of the aperiodic task, the DD increases the refresh rate to its original value.

Apparatus and methods for universal serial bus 4 (USB4) data bandwidth scaling

Three components are used to adjust the CPU peak power based on the USB TYPE-C device states. These components include operating system (OS) Peak Power Manager, USB TYPE-C Connector Manager, and USB TYPE-C Protocol Device Driver. The USB TYPE-C Connector Manager sends a synchronous request to the OS Peak Power Manager when a USB TYPE-C power sink device is attached or detached, and the USB TYPE-C Protocol Device Driver sends a synchronous request to the Peak Power Manager when the power sink transitions device state. The Peak Power Manager takes power budget from the CPU when the USB TYPE-C connector is attached to a power sink and is active (e.g., high power device state), and gives back the power budget to the CPU for performance when the USB TYPE-C connector is either detached or the attached and power sink device is idle (lowest device state).

Apparatus and method for dynamic reallocation of processor power by throttling processor to allow an external device to operate

Aspects of the embodiments are directed to a ThunderBolt (TBT) input/output (I/O) controller apparatus. The TBT I/O controller apparatus can include an output port to receive a connection to a display device; a multiplexer coupled to the output port; a first input port coupled to the multiplexer; a second input port coupled to the multiplexer; a memory element to store graphics preference data; and TBT firmware (FW). The TBT FW can detect a connected device at the input port; determine a graphics processor for the connected device based on the graphics preference data; and logically connect the connected device to one of the first input port or the second input port through the multiplexer based on the determined graphics processor.

Method, apparatus, system for thunderbolt-based display topology for dual graphics systems

Embodiments may include systems and methods for communication including a communication port with a first lane and a second lane, a first power controller and a second power controller coupled to the communication port. The first power controller is to control, at a first time instance, the first lane to operate in a first power state selected from a first set of power states for the first lane. The second power controller is to control, at a second time instance, the second lane to operate in a second power state selected from a second set of power states for the second lane, wherein the first power state is different from the second power state. Other embodiments may be described and/or claimed.

Power state management for lanes of a communication port

An apparatus may comprise a port to couple to a plurality of communication paths comprising a first, second, third, and fourth communication path, the communication paths each having a direction of either a receive path or a transmit path, the communication paths comprising a first communication path having a direction that may be selectively configured as a receive path or a transmit path. The apparatus further comprises a controller comprising circuitry, the controller to in response to a communication path reconfiguration command, reconfigure the direction of the first communication path such that the first communication path, second communication path, and third communication path have the same direction and the fourth communication path has a direction opposite to the direction of the first, second, and third communication paths.

Dynamic asymmetric communication path allocation

This disclosure describes systems, methods, and devices related to wireless charger cross-talk prevention system. A power transmitting unit (PTU) may determine a power receiving unit (PRU) of one or more PRUs in proximity to a charging area of the PTU. The PTU may detect a communication link between the PTU and the PRU. The PTU may generate an enhanced message, including one or more identifying information associated with the PTU. The PTU may cause to send the enhanced message to the PRU.
