Linux kernel 7.1 sends Intel 486 support to silicon heaven

More than 140,000 lines of code bite the dust as ancient CPUs, bus mice, and other legacy leftovers face the chop

Why this matters
Why now

The continuous evolution of software and hardware necessitates the removal of support for outdated components to optimize maintenance and performance.

Why it’s important

This reflects the ongoing cycle of technological obsolescence, where supporting legacy hardware becomes a drain on development resources and performance.

What changes

Older Intel 486-based systems will no longer be officially supported by the latest Linux kernel, pushing users of such systems towards older kernel versions or hardware upgrades.

Winners
  • · Modern CPU manufacturers
  • · Software developers (reduced legacy burden)
Losers
  • · Users of legacy Intel 486 hardware
  • · Companies with deeply embedded, ancient systems
Second-order effects
Direct

The Linux kernel codebase becomes leaner and potentially more efficient.

Second

It implicitly encourages upgrades to newer, more powerful hardware for those wanting the latest kernel features and security.

Third

This contributes to the broader trend of increasing computational power requirements for modern software ecosystems.
