Systems and methods may provide for receiving, at a controller of a first device having a host processor, user input data and converting the user input data into one or more packets. Additionally, the one or more packets may be sent to a wireless communication component of the first device. In one example, the one or more packets are sent to the wireless communication component while the host processor is in one or more of a sleep state or a low power state.

Power and cost efficient peripheral input

A method and system for sending an interrupt signal is described herein. The method may include detecting sensor data in a sensor controller and detecting a powered down port between the sensor controller and an operating system. The method may also include sending the interrupt signal from the sensor controller to the operating system. In addition, the method may include detecting the operating system has provided power to the powered down port. Furthermore, the method may include sending the sensor data from the sensor controller to the operating system.

USB device interrupt signal

A disclosed data processing system includes a processor and an operating system kernel that includes communication drivers to support sideband interrupt deferring of polling associated with I/O requests. The communication drivers may implement a driver stack that includes a sideband miniport driver to detect an application program read request for device data from an input/output (I/O) device. The I/O device may be a sensor or another type of human interface device. The sideband miniport driver may pend the read request and maintain an interrupt pipe of a communication transport between the host system and the I/O device in a disabled state. With the interrupt pipe disabled, the host system drivers are unable to poll the I/O device. The sideband miniport driver may pend the read request and keep the interrupt pipe disabled until a sideband interrupt is communicated to the sideband miniport driver.

Polling of I/O devices on host initiated communication transports

A method of providing position support to a main processor of a computing device is disclosed. The method may include receiving primary position data from a sensor at a sensor controller. The method may also include analyzing, via the sensor controller, the primary position data to determine secondary position data. The method may also include formatting, via the sensor controller, the secondary position data. The method may also include aggregating, via the sensor controller, the formatted position data. The method may also include providing, via a single channel interface between the sensor controller and the main processor, the aggregated position data to an operating system installed on the main processor. The method may also include communicating, via a driver installed on the operating system, the position data to an application installed on the operating system.
