OpenPOWER is really open, including the chip's firmware (https://github.com/open-power https://github.com/open-power), and there's no embedded management chip as found in Intel or AMD CPUs.
- wmf 10y agoPeople may be overselling this; all the current Power8 machines are servers that have BMCs.
- wyldfire 10y agoParent posts are likely referring to on-CPU management features (on the IC itself), not on-board ones like BMCs.
- cm3 10y agoThe BMC's firmware is also open: https://github.com/open-power/hostboot https://github.com/open-power/hostboot Here's a blog post with some details: https://blog.jms.id.au/2015/07/openpower-firmware-stack/ https://blog.jms.id.au/2015/07/openpower-firmware-stack/
- ajdlinux 10y agoHostboot (and skiboot) is loaded from the BMC, but it's not the BMC firmware - hostboot and skiboot run entirely on the host. The BMC firmware we're currently working on at IBM (based off some work by Facebook) is at https://github.com/openbmc/openbmc https://github.com/openbmc/openbmc. [Disclosure: IBM Power Systems.
