I think it should have been announced by now (or soon). IBM is completely opening up the Power ISA. Additionally, the OpenPower foundation will migrate to be under The Linux Foundation. They will also be contributing a few other things like a new softcore.https://twitter.com/david_schor/status/1163793571566112769?s=19 …
Do I understand correctly that the Linux Foundation for the first time is going to handle hardware specs, not only support (with SW) and promote open hardware? This is quite a stretch
