The Intel 486 processor, a stalwart in the computing world for 37 years, is on the verge of being phased out from contemporary Linux systems. As reported by tech outlet Phoronix, Linux kernel developers have embarked on a mission to eliminate support for the 486 processor, with pertinent patches slated for integration into the Linux 7.1 kernel. This move signals the beginning of the end for this iconic CPU's tenure in the latest iteration of the Linux operating system.
The 486 processor made its debut in 1989, and the writing has been on the wall regarding its eventual removal from support. Linus Torvalds, the visionary behind Linux, has previously remarked that sustaining support for the 486 held little practical value and even impeded the pace of development. The patch responsible for its removal was submitted by the esteemed kernel developer Ingo Molnar, who excised the core build configuration options pertaining to the 486 from the kernel.
Molnar highlighted that maintaining intricate hardware compatibility code for seldom-used, antiquated 32-bit CPUs often led to complications. He emphasized that developers' energies would be better directed toward more rewarding development endeavors. Once the patch is incorporated into the Linux 7.1 kernel, users will no longer have the capability to construct kernel images tailored for the 486 processor. Those who persist in utilizing 486 hosts to run modern Linux distributions will be left with the options of either sticking with the existing LTS (Long-Term Support) kernel or upgrading their hardware infrastructure.
