SYSTEM-WIDE TIME SYNCHRONIZATION ACROSS POWER MANAGEMENT INTERFACES AND SENSOR DATA
First Claim
1. A power management control system for an information handling system, the power management control system comprising:
- a power management interface bus interfacing a plurality of devices, wherein one or more of the devices is each associated with a time clock; and
a management agent interfacing the power management interface bus, wherein the management agent is configured to;
receive a system time;
synchronize the one or more time clocks based, at least in part, on the system time; and
maintain synchronization of the one or more time clocks, at least in part, via a set of telemetric primitives.

Abstract
A power management control system for an information handling system is disclosed. The power management control system includes a power management interface bus interfacing a plurality of devices, where one or more of the devices is each associated with a time clock. The power management control system further includes a management agent interfacing the power management interface bus. The management agent is configured to: receive a system time; synchronize the one or more time clocks based, at least in part, on the system time; and maintain synchronization of the one or more time clocks, at least in part, via a set of telemetric primitives.

9. A method for providing system-wide time synchronization across power management interfaces, the method comprising:
-
providing a set of primitives to a controller to retrieve and control time information, at least in part, with one or more of the primitives, wherein the time information is associated with a plurality of devices coupled to a power management interface bus, and wherein one or more of the devices is each associated with a time clock; and providing a set of telemetric primitives to the controller to synchronize the one or more time clocks based, at least in part, on one or more of the telemetric primitives and timestamp information received via the power management interface bus. - View Dependent Claims (10, 11, 12)
