How well is the risc-v instruction set supported? Are there linux or bsd distros and compiler toolchains available without needing a month of research to find them?
The tool chains are coming along nicely. Not sure they are ready for primetime. But likely are. The biggest issue is the lack of hardware. I do know some distros have been heading in that direction. Don't know if anything is actually rolled out.
The instruction sets are broken down into extensions. So compilers will simply be told for which extensions to include support.
The esp uC guys appear to be heading to the risk v direction. Iirc, that's the instruction set for their low power processor. And iirc, the newer C line of uCs. They did this because the instruction set appears ahead of expressive's own efforts.
Take comment with grain of salt as I'm parroting.

Not really.
Heh seems like something interesting to get and play around with if you like doing everything from scratch. I wonder if you could get a stripped down no systemd linux kernel to compile.
That's kind of what RISC V is. Since you can make a CPU as complex or as simple as you need it, there aren't really standard toolchains or other gadgets available.
