The Linux kernel has officially dropped support for the Intel 486 processor, a CPU architecture dating back to 1989.
Linux creator Linus Torvalds commented that there is 'zero real reason' to maintain support for hardware that is 37 years old. The decision marks a clean symbolic break as Linux focuses development resources on modern ARM, RISC-V, and x86-64 architectures.
The i486 removal cleans up approximately 3,000 lines of legacy code from the kernel. While the practical impact is minimal — virtually no one runs current Linux kernels on 486 hardware — the decision is significant as a statement of priorities.
Torvalds noted: 'We have better things to do with our time than maintain compatibility with hardware that hasn't been manufactured in 20 years. Every line of legacy code is a line that someone has to understand and maintain.'
The Linux kernel community has been gradually removing support for obsolete architectures. Previous removals include the Itanium (IA-64) architecture in 2024 and the SuperH (SH) architecture in 2023.
