Abstract
Methods, systems and apparatuses may provide for technology that includes a system on chip (SoC) having a root of trust and an embedded controller to conduct functional safety operations and non-functional safety operations with respect to the SoC. The technology may also include an enhanced serial peripheral interface (eSPI) coupled to the SoC and the embedded controller, wherein the eSPI is to tunnel communications associated with the functional safety operations between the embedded controller and the root of trust.
