- stefan_ 4y agoMeanwhile, the RISC-V "ecosystem" is already a full shambles, with companies shipping chips implementing preliminary, not 1.0 released extensions and adding on their own proprietary extension instructions. It's like ARM before v7 or v8, only dumber, because at least ARM back then had an excuse for why they were fracturing it all so badly. Also, of course, ARM has lots of other IP you need to build a full-blown smartphone SoC; think GPU, display processors and pipelines, video accelerators, ... - to make a RISC-V smartphone you will have to buy all of those in because there is no "RISC-V ecosystem" replacement (and it's rather unlikely there ever will be) and at that point... what's the point anymore?
- anfilt 4y agoThe chips using preliminary/draft specs are annoying. However RISC-V has allocations dedicated in the ISA for vendor specific instructions which is fine. Code that does not use such extensions runs just fine
