This is wonderful! Also what a fantastic partnership that allowed adding a new CPU to that die. Kudos to them.

I had a lot of trouble finding out which open source license applies. Wikipedia’s RISC-V page doesn’t seem to say; its citation for being released under open source doesn’t seem to say which one either.[0] Could be wrong. Exhausted after working all day. But it’s not front and center…

On the RISC-V site I thought it might be more prominent too but if it is I missed it. I found some docs there licensed Creative Commons. Is that the license for the entire CPU? Even layouts and everything that is past the ISA to actual silicon?
