This is so cool - I'd like an open source CPU in my next phone please!

(Of course, I would also like it to be fast, so that will probably not happen in the next 5 years)

The article doesn't say if their port is also open source. There's a blog post here but I don't see any patches. https://riscv.org/blog/2021/11/how-alibaba-is-porting-risc-v...

Just because it's RISC-V doesn't mean the CPU is open source.

Not all RISC-V ends up open, but it has better odds than anything else.

AliBaba has been open sourcing their designs though. AFAIK, this work is mainly against their XuanTie C910 cores that have the source published here: https://github.com/T-head-Semi/openc910

Yeah. It's not licensed under the GPL or anything like that. I'm not sure it's as good as people seem to think.

I think this [0] is their Android port. You'll also find four RISC-V cores under that account that Alibaba open sourced near the end of last year.
