In this episode of The Linux Podcast, Lucas and Luna dive into how the Linux intel_pstate and amd_pstate drivers are changing the way CPUs manage power and performance. They break down why frequency scaling matters for modern workloads—from laptops to servers—and how the newer EPP (Energy Performance Preference) and HWP (Hardware P-State) controls give users fine-grained tuning. Lucas shares a concrete example: a datacenter running 10,000 servers saved 8% on electricity simply by switching from the old acpi-cpufreq to intel_pstate with the 'powersave' governor. Luna pushes back on whether users should always pick performance mode, and they explore how the kernel's schedutil governor bridges scheduling and power decisions. The episode wraps with a look at upcoming changes in the 6.x kernel tree, including amd_pstate's active mode for Ryzen and Threadripper chips.
