Whereas POWER9 was large for open-source followers with the formation of the OpenPOWER Basis and Raptor Computing Methods designing POWER9-based methods which might be totally open-source all the way down to schematics and the motherboard firmware, the identical can’t be at the moment stated about POWER10.
Whereas IBM has printed plenty of the POWER10 firmware as open-source, remaining closed for no less than the time being is their off-chip OMI DRAM bridge and their on-chip PPE I/O processor.
This sucks. I’m an enormous fan of Raptor’s totally open POWER9 workstation and boards, and regardless of Raptor hinting for months now there have been points with POWER10’s openness, I hoped issues could be discovered earlier than the discharge of IBM’s new POWER10 processors this month. Sadly, this appears to have been wishful considering. Raptor’s POWER9 workstations are the one totally open performance-oriented computer systems you will get, and till IBM decides in any other case, it’s going to remain that method.
That simply sucks.
