As part of the constant evolution of the operating system Linux, a recent innovation deserves particular attention: the introduction of the option CONFIG_X86_64_NATIVE for kernel builds. This advance aims to optimize kernel compilation for micro-architecture x86_64 by allowing users to take advantage of the specificities of their CPU. This article looks at this new patch, its usefulness and its potential impact on system performance.
CONFIG_X86_64_NATIVE Overview
Main functionality
The functionality CONFIG_X86_64_NATIVE will allow users to adapt the compilation of their Linux kernel directly according to their hardware. By activating the option -market=native, each kernel compiler will take into account the specifics of the CPU it is running on. The implications are:
- Optimizing kernel performance by taking advantage of kernel-specific instructions CPU.
- Facilitating the compilation process for users by avoiding complex configurations.
- Improved compatibility and stability by minimizing potential errors related to hardware incompatibilities.
Community reactions
Following the release of this patch, reactions within the Linux community were mixed. Although some experts applaud the idea of optimized compilation, others express reservations due to the possible poor performance it could cause in certain environments. Nevertheless, these adjustments are causing obvious interest in the technical community, particularly among developers and system administrators.
Improvements made by the patch
Feedback on certain removed features
This patch also resulted in the removal of other configuration options that were considered obsolete or irrelevant to the new realities of microarchitecture development. x86_64. This includes the decision to maintain compatibility with systems 32 bit for the moment, despite the debates around their future in the Linux landscape.
Implications for virtual systems
Kernel updating can also impact virtualization systems. The decision to preserve host support KVM in 32 bits demonstrates a concern for continuity for users who manage complex virtual environments.
