From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Soon, my friend, soon.
The biggest advantage is that there is no royalties, like the ARM requires.

I'm not sure that's big enough of an advantage though. I hope it is but history shows that most people are more than willing to pay for convenience over freedom.

Check out MilkV, they have a 64 core RISCV workstation that supports PCIe at full speeds and has NVMe and SATA slots like a completely normal x86 motherboard.

People have gotten modern AAA games running on it.

If you license a design from someone you'll still be paying something. Sure there are also free implementations but they are aimed at microcontrollers, you won't get any server class chips for free.

I do not think it is about the royalties in most cases. I mean, RISC-V royalties may be the reason you choose it over ARM for a custom chips ( say in the bajillion SSDs you are going to ship ). Perhaps you were going to choose a different ISA for a microcontroller and the lack of license fee makes RISC-V attractive.

For chip maker, it is the freedom that matters as that is what “convenience” means to them. And it means less risk. Look at the Qualcomm / ARM lawsuits right now. That would not happen if Qualcomm had chosen ARM.

And if you are a chip maker licensing core designs, do you want your ISA to force you into a monopoly? ARM is more mature today but the role that ARM the company plays is being filled by multiple RISC-V suppliers ( HiFive, Milk-V, etc ). More players means more completion means more choice and probably better prices. ARM’s core business is licensing chip designs and they are about to have a lot of competition from RISC-C.

And in the end, competition from and within the RISC-V space will drive down prices for consumers. That is what consumers are going to care about. The lower prices will not really be because of lower license fees ( though that will help of course ). And it all comes with a large and open software ecosystem. So the “convenience” will be there too.
