US 2019/0155361 A1 · POWER STATE MANAGEMENT FOR LANES OF A COMMUNICATION PORT

Abstract

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.

Dependent claims

An apparatus for communication, comprising:

a communication port including a first lane and a second lane;
a first power controller coupled to the communication port 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;
and
a second power controller coupled to the communication port 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.

1 more element

One or more non-transitory computer-readable media comprising instructions that cause a controller, in response to execution of the instructions by the controller, to:

control a first lane of a communication port, at a first time instance, to operate in a first power state selected from a first set of power states for the first lane;
and
control a second lane of the communication port, at a second time instance, 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.

An apparatus for computing, comprising:

a printed circuit board (PCB) having a processor;
a communication port including a first lane and a second lane disposed on the PCB, wherein the communication port is a part of a input/output (I/O) interface that is compliant with a peripheral component interconnect (PCI) protocol;
and
a controller disposed on the PCB and coupled to the first lane and the second lane, wherein the controller is to:
control the first lane of the communication port, at a first time instance, to operate in a first power state selected from a first set of power states for the first lane;
and
control the second lane of the communication port, at a second time instance, 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.
