On-Chip Controller (OCC): Auxillary Power ISA microprocessor on OpenPOWER CPUs. Periodically monitors chip workload, power consumption and temperature readings. Transmits temperature readings to the BMC to allow it to set appropriate fan speeds. The OCC implements any applicable power caps and supports programmable TDP limits.
OCC firmware is loaded at boot as part of the boot process and is open source.
