Power monitoring in a firmware framework

An Information Handling System (IHS), comprising:

• a controller, wherein the controller comprises firmware that, upon execution by a processing core, causes the processing core to instantiate an orchestrator of a firmware framework;
• and
• a plurality of devices coupled to the controller, wherein each device of the plurality of devices comprises firmware that, upon execution by a corresponding processing core, causes the corresponding processing core to instantiate a respective node in the firmware framework, and wherein the orchestrator is configured to:
• in response to an indication of a transition of the IHS into a sleep, hibernation, or modern standby mode, send a command to each of the plurality of devices to enter a selected low-power state;
• monitor power consumption of each of the plurality of devices while the IHS is in the sleep, hibernation, or modern standby mode;
• and
• based at least in part upon the power consumption, identify one or more power offenders, among the plurality of devices, without any involvement by any host Operating System (OS) of the IHS.
