It's the difference between export limits on specific chips – and a problematic blanket ban
The possibility of America placing sanctions on RISC-V has increased the pressure on RV's governing body and its partners to get their messaging right about what this technology really is.
In the eyes of the RISC-V world, the latter – if applied to RISC-V – would be unfair overkill. It would be a blanket ban on all RISC-V-compatible processors rather than just those specifically chosen by a government on, say, national security grounds. As such, the community is hoping to educate everyone on the distinction between open source and open royalty-free specifications.
Though seemingly innocuous, draping RISC-V in the open source banner resulted in unforeseen consequences. "Due to this, the terms 'open source' and 'standards' were often used interchangeably. We realized this was causing confusion as there are nuances between standards and open source software. Hence, we have made a concerted effort to update our terminology for greater clarity and consistency in our work as a standards body."
RISC-V advocates protest this characterization of the ISA as"open source" – it isn't a distinct technology to ban, in their eyes.spoke to RISC-V International and outfits that design their own RV-compatible processors, and they pretty much all argued that sanctions wouldn't merely be disruptive and terrible publicity, they'd be more or less impossible to enforce.
Another facet to this is that RISC-V International is based in Switzerland, while a lot of RV CPU design work is done in the US or within reach of Uncle Sam. It would be interesting, to say the at least, to see how export controls on the ISA might work in that context.
That's not even mentioning the fact that China struggles to produce advanced chips at scale, andIt's difficult to get politicians to listen, but it's not risky at the moment
