Appl. No.:

13/175723

Inventors:

Christopher J. Lake - Folsom CA, US

International Classification:

G06F 1/26

US Classification:

713300

Abstract:

Techniques for determining a communication interface of a computer platform. In an embodiment, a power management unit of a computer platform provides to an agent of the platform an indication of a power state. In certain embodiments, the agent determines, based on the indication of the power state, that an interface is expected to be available. The agent may designate information for transmission via the first interface—e.g. in lieu of transmitting the information via a second interface which is available prior to the first interface becoming available.

Abstract:

Methods and apparatus for managing sideband segments in an On-Die System Fabric (OSF) are described. In one embodiment, a sideband OSF includes a plurality of segments that may be reset or powered down independently after power management logic determines that in progress messages have been handled and future messages to the segment being reset or powered down will be blocked. Other embodiments are also disclosed.

Abstract:

Embodiments of computer-implemented methods, systems, computing devices, and computer-readable media are described herein for transitioning a computing device between a first state in which the computing device uses a first amount of power and a second state in which the computing device uses a second, greater amount of power. The computing device may include a shared wake pin to which a first external device and a second external device may be operably coupled, and a communication bus to which the first external device is connected and the second external device is not. Responsive to receipt of a wake signal at the wake pin, the computing device may transition between states, send an instruction to the first external device over the communication bus, and determine whether the first or second external device initiated the wake signal based on a response at the wake pin.
