Abstract
A method and device that implements communication over an interconnect to support improved power distribution over the interconnect. The device includes a controller to implement a device policy manager (DPM) to manage power allotment over the interconnect, and a battery feedback mechanism coupled to the controller, the battery feedback mechanism to detect a low or dead battery condition of a connected device over the interconnect and to indicate to the DPM to advertise a higher power charging level to the connected device.
Claims12
A device to implement communication over an interconnect to support improved power distribution over the interconnect, the device comprising:
- a controller to implement a device policy manager (DPM) to manage power allotment over the interconnect, the controller to provide a default power over the interconnect to a connected device upon connection to the connected device, the connected device separate and remote from the device;
- and
- a battery feedback mechanism coupled to the controller, the battery feedback mechanism to detect a low or dead battery condition of the connected device over the interconnect and to indicate to the DPM to advertise a higher power charging level to the connected device, in response to a failure of the connected device to respond to communication from the controller.
A method of a first device to manage power distribution over an interconnect, the method comprising:
- advertising, by the first device, a default power charging level and providing a default power on the interconnect upon connection with a connected device;
- determining whether the connected device has a dead or low power state by a battery feedback mechanism of the first device monitoring power consumption on the interconnect in response to a failure of the connected device to respond to communication and complete a connection over the interconnect with the first device;
- and
- increasing, by the first device, a power charging level on the interconnect in response to detecting the dead or low power state of the connected device.
