OpenPOWER Firmware is an open-source alternative to OpenFirmware and proprietary IBM firmware used on Power machines.[1] It is a general name for many separate pieces of software used to start recent Power Architecture chips made by IBM.[2]
OpenBMC is a separate project that creates firmware for the Baseboard Management Controller.
Components
- Self-Boot Engine (SBE) code - loads Hostboot on a CPU core
- Hostboot - loads Skiboot
- Skiboot - implements OpenPOWER Abstraction Layer (OPAL), loads Petitboot, and loads OCC code into the OCC core
- Petitboot - loads the operating system
- On-Chip Controller (OCC) code - controls thermal regulation on the chip
