Linux

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.

Well, kind of 3 companies.

Intel and AMD both have rights to x86_64, since they both held patents used by it. In 2021, AMD’s patents expired.

Then there’s ARM, which is solely owned by Arm Holdings.

But yes, it’s still very much a big problem, and I really hope RISC-V succeeds to solve that problem. Licensing core designs is a much better motive and business model than licensing an entire ISA.

Edit: oh wait, you said two architectures, not two companies. Never mind, you’re right. :)
