In-Depth Analysis

The RFC patch series proposes removing support for i486 and early Pentium (i586) processors from the Linux kernel. The rationale behind this move is based on several factors:

The patch series doesn’t specify the exact amount of code that will be removed, but it implies a significant reduction in the overall kernel size and complexity. The RFC stage allows for discussion and feedback from the community before the patch is potentially merged into the main kernel tree. This ensures a careful evaluation of the impact and potential alternatives.

Commentary

Dropping support for older architectures is a common practice in software development, as it allows developers to focus on supporting newer, more relevant hardware. While some users might be affected, the overall impact is expected to be minimal, given the age and rarity of i486 and early Pentium processors.

This move reflects the ongoing effort to streamline and optimize the Linux kernel. By removing support for outdated hardware, developers can reduce the maintenance burden, improve code quality, and potentially enhance performance on modern systems. It is a pragmatic decision driven by the need to balance compatibility with maintainability.

Strategic considerations likely involve resource allocation. Developer time and testing resources are finite. By removing this support, those resources can be directed towards more strategically important areas, such as supporting new hardware, improving security, and optimizing performance on modern platforms.
