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 an IBM POWER chip.[2]
Components
- SBE code - loads Hostboot an a CPU core
- Hostboot - loads Skiboot
- Skiboot (implements OPAL) - loads Petitboot and loads OCC into the OCC core
- Petitboot - loads the operating system
- OCC - controls thermal regulation on certain IBM POWER chips (such as POWER9, POWER8)
