The term x86-64v3 is once again a discussion point for Linux users, sparking curiosity and questions about its relevance to the platform. But what is it, why does it matter to Linux, and what is all the fuss about? Find out everything you need to know about x86-64v3 below.
A brief overview of microarchitecture history
The story of the x86 instruction set began about 39 years ago with the introduction of the Intel 80386, commonly referred to as the 386. This was a pivotal moment in the history of modern desktop and server computing. Launched in 1985, the 386 was Intel’s first 32-bit processor and was equipped with a full memory management unit, enabling it to run operating systems that utilize virtual memory. However, the evolution of x86 technology didn’t stop at the 386. Over time, this older chip, its microarchitecture, and its instructions were phased out. Debian Linux discontinued 386 support in 2005 and completely removed it in 2007. The Linux kernel followed suit in 2012, despite Linux’s original development on 386 and 486 machines.
