I have increasingly negative things to say about this.
There is (so far) nothing 'open' about RISC-V. and I wonder if there really ever was any desire for it, at this point.
This whole "Open ISA" crap appears to be a thin veneer to funnel quite large sums of investment into an otherwise completely proprietary and locked-down environment that could never harm the incumbents in any meaningful way - while still maintaining just enough of a pretense of open source, that the (regrettably myself included) shallow nerds and geeks could get smitten by it.
Where is the RTL? Where are the GDSII masks? Why am I unable to look at the branch predictor unit in the Github code viewer? Or (God forbid!) the USB/HDMI/GPU IP? I reject the notion that these are unreasonable questions.
I want my SoC to have a special register that has the git SHA ID of the exact snapshot of the repository that was used to cook the masks. that, now that - is Open Source. that is Open Computing. And nothing less!
I dont care about the piece of paper with instruction encodings - the least interesting part of any computer!
Wasn't that the whole point? We're more than a quarter of a century in and we're still begging SoC vendors for datasheets. Really incredibly embarassing and disappointing.
