General Purpose Engine (GPE): A type of auxillary microprocessor on a POWER9 chip which assists the OCC in its power management duties.
Two types of GPE exist on POWER9 chips:
- Stop GPEs (SGPEs) are involved in resuming core execution after execution of a STOP instruction (a Power ISA instruction which halts core execution).
- Pstate GPEs (PGPEs) manage core power states.
The firmware that runs on the GPEs is called HCODE.
