Platform Environmental Control Interface

Platform Environmental Control Interface (PECI) is an Intel proprietary interface that provides a communication channel between Intel processors and external components such as Super IO (SIO) and Embedded Controllers (EC) to provide processor temperature, Turbo, Assured Power (cTDP), and Memory Throttling Control mechanisms and many other services. PECI is used for platform thermal management and real-time control and configuration of processor features and performance.

Note:PECI over eSPI is supported.
