The upcoming Linux Kernel 6.15 is set to phase out support for Intel's 486 and earlier processors. This change, implemented by veteran developer Ingo Molnar, involves a significant code reduction of nearly 15,000 lines, resulting in stricter requirements for x86-32 CPUs. Notably, the kernel will require support for the Timer Stamp Counter and the CMPXCHG8B instruction. This shift hints at Linux's ongoing evolution, marking the end for older architectures and the elimination of software emulation for floating-point units, thereby streamlining future development.
Kernel 6.15 will eliminate support for Intel's 486 and earlier chips, symbolizing a significant progression in Linux's evolution and hardware requirements.
