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.

How is RISC-V better than arm for Linux? (programming.dev)

Help me understand this better.

From what I have read online, since arm just licenses their ISA and each vendor's CPU design can differ vastly from one another unlike x86 which is standard and only between amd and Intel. So the Linux support is hit or miss for arm CPUs and is dependent on vendor.

How is RISC-V better at this?. Now since it is open source, there may not be even some standard ISA like arm-v8. Isn't it even fragmented and harder to support all different type CPUs?

Better for Linux? I'm not sure I would say it is. Better for the world in general? When you compare things like power consumption, you can definitely see that in some use cases (the average user), ARM is superior. But for Linux? Maybe by default owing to the fact that it's more modern. As for RISC-V, the core is open source and "all" the extensions are proprietary, so it's not as open source as it pretends to be. But it's definitely better than what we're currently accustomed to as mainstream.
