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?

Thank you for the great write-up. Man, I sometimes regret not having studies computer science. I am really invested in open source and net neutrality etc., but I can't contribute shit so I'm restricted to a mere consumer.

I'm just happy that my garuda linux just keeps working most of the time becaus I couldn't code anything if my devices would fail.

I got graduate and masters in the hardware area but learned all of those things about arm and riscV by myself. I only got to see mips and hypothetical ISA in my courses. Heck riscV and rpi didn't even exist.

All you need is interest and time.

That's not true! Contributing documentation improvements is critically important for the growth and health of the open-source community but is very overlooked.
