I have a HiFive Unleashed, one of those used to demo them at the Embedded Linux Conference in Portland in March 2018. It was over a year after that before the ISA was ratified (and of course designed well before that) so, as I said, there was no guarantee that it would actually qualify as "RISC-V" long term.
With the HiFive Unleashed SiFive "shipped a draft spec", which is exactly the same thing they shit on Canaan (K210, priv arch 1.9.1, literally a snapshot of the Rocket repo) and THead (C906/C910 RVV 0.7.1) for. They just got lucky that no breaking changes were made, unlike the other guys.
