Introduction: What is <code>powercap-utils</code>?</h3> <p><code>powercap-utils</code> is a suite of user-space command-line tools for Linux that allow you to interact with the kernel&rsquo;s <strong>Power Capping Framework</strong>. This framework provides a standardized way to monitor and limit the power consumption of hardware devices.</p> <p>Its most common use is to control <strong>Intel&rsquo;s Running Average Power Limit (RAPL)</strong> and <strong>AMD&rsquo;s RAPL-like features</strong> on modern CPUs. These features let you directly set power budgets for the CPU package, its cores, and DRAM.</p>
