It is Chinese companies looking for ARM alternative that push this otherwise mediocre ISA.
It is possible that ARM based CPUs will start eating x86 market slowly. See snapdragon X2 and upcoming Nvidia CPU. Maybe in 10 years new computers will be ARM based and a lot of IoT will run on risc-5.
Why "mediocre"? I've written production assembly language for a half-dozen different processor architectures and RISC-V is my favorite by far.
Really? Didn't China pirate the entire ARM China company and start spamming cores like Star1
"It is Chinese companies looking for ARM alternative"
The V in RISC-V represents iteration of the ISA, over the last 46 years, most of which occurred in the US, mainly at Berkeley.
