RISC-V CPUs don't have any of that as there's no requirement that actual implementation be open source, only the ISA. And it's not like you can change it. You can't buy a RISC-V CPU and fiddle with the design, you don't get the source nor the toolchain. All you get are the man pages, and guess what? You get those with x86 and ARM, too!

There's a growing list of RISC-V cores that are themselves open source (that's how RISC-V ecosystem got started, btw). And unlike in x86 or ARM world, no-one would hassle you for licensing or royalties if you bring those designs to a foundry & mass-produce. Now as for say, GPUs to stick onto those, that is another matter.
