Tunneling functional safety communications over an enhanced serial peripheral interface

An apparatus comprising:

• a system on chip (SoC) including a root of trust;
• an embedded controller to conduct functional safety operations in compliance with one or more safety requirements and conduct non-functional safety operations;
• and
• an interface coupled to the SoC and the embedded controller, wherein the interface is to tunnel communications associated with the functional safety operations between the embedded controller and the root of trust, wherein the interface is an enhanced serial peripheral interface (eSPI).

At least one non-transitory computer readable storage medium comprising a set of instructions, which when executed by an embedded controller, cause the embedded controller to:

• conduct functional safety operations with respect to a system on chip (SoC) including a root of trust;
• conduct non-functional safety operations with respect to the SoC;
• and
• tunnel communications associated with the functional safety operations to the root of trust via an enhanced serial peripheral interface (eSPI).

A method comprising:

• conducting, by an embedded controller, functional safety operations with respect to a system on chip (SoC) including a root of trust;
• conducting, by the embedded controller, non-functional safety operations with respect to the SoC;
• and
• tunneling communications associated with the functional safety operations from the embedded controller to the root of trust via an enhanced serial peripheral interface (eSPI).
