Linux CPU Time Guardians: Understanding cputime, cpufreq_stats, cpufreq_times, and cpuidle_time
The article explains Linux kernel CPU‑time accounting modules—cputime, cpufreq_stats, cpufreq_times, and cpuidle_time—detailing how each records processor usage, frequency transitions, per‑process frequency data, and idle‑state durations, and why they are essential for performance analysis and power‑optimization by system engineers.
