Linux

The RISC-V port was just merged to Linux a few minutes ago. This means we will be in the 4.15 release, which should be out about 10 weeks from last Sunday. As soon as the tarballs are created, the RISC-V Linux ABI will be stable, and since we'll ideally be in a glibc release that comes out soon after that we'll be fully ABI stable by early in February.

RISC-V is a completely free and open ISA that hasn't seen much adoption just yet.

ubuntu is not such a force on the desktop as to drive the adoption of a specific architecture.

RISC-V is going to be mainly used on the domain of academic research for a long time, if anything it may see some adoption on some mobile devices, or most likely IoT applications.

It's too late for a non x86 part to make a dent on the desktop/laptop space.

Open source CPU will gain adoption in server/cloud platforms. Google and Rackspace already have open server using POWER9 CPU.

Zaius is an open design, but POWER9 is not open itself. RISC-V is open all the way down to the RTL

This is not 100 percent sure. The ability for new cpu to enter market space are becoming more possible. Its all about the nm limit. We cannot keep on going smaller forever

3nm production is targeted to come on line for 2019. After that 1 nm and 0.5 nm might be possible. Then that is it. Then it will be focus on how the chip is internally designed and longer development cycles.

So it might not be possible for a non x86 at the moment but 5 to 10 years after silicon production hits limit all bets will be off particularly as production costs start to drop.

Risc-v chips form SiFive are already appearing in devices. You see the first chips in 2016 and the first IoT devices using Risc-v are already on the market.
