The recent patch in the Linux kernel (version 6.13) addresses energy efficiency by modifying the busy polling feature used in high-performance networking applications, particularly relevant for data centers. This change enables the kernel to disable busy polling when systems are idle, significantly reducing energy consumption. Users note that most Linux applications do not utilize this feature, making the system wasteful in idle states. While this improvement is promising for energy conservation in data centers, it may not align with desktop workloads, leading to some confusion regarding its applicability. The discussion highlights the importance of code efficiency, especially in high-performance computing settings, where power waste can be substantial over lengthy processing tasks.
