"RiscV" ? Isn't that some old IBM flavor of Unix from like 30 years ago?
Its a CPU architecture. x86, ARM, RISCV all CPU architectures
Sure, but I don't hear much about Risc these days, mostly x86 and ARM .. Is Risc still used for much?
Nothing mainstream, but it has some niche hype around it because of open source programmability reasons.

Looks like word has gotten around ;D
Why support krux but you are more critical on pi projects... Riscv so much more secure?
