WebCPUFreq uses struct cpufreq_policy as its basic data type and the design of its user space interface is based on the policy concept. CPU Initialization¶ First of all, a scaling driver has to be registered for CPUFreq to work. It is only possible to register one scaling driver at a time, so the scaling driver is expected to be able to handle ... WebRed Hat Training. 3.2. Using CPUfreq Governors. One of the most effective ways to reduce power consumption and heat output on your system is to use CPUfreq. CPUfreq — also referred to as CPU speed scaling — allows the clock speed of the processor to be adjusted on the fly.

CPU frequency and idle states - Google Open Source

WebCPUfreq, also referred to as CPU speed scaling, is the infrastructure in the Linux kernel that enables it to scale the CPU frequency in order to save power. CPU scaling can be done automatically depending on the system load, in response to Advanced Configuration and Power Interface (ACPI) events, or manually by user-space programs, and it ... WebReference counting of the cpufreq policies is done by cpufreq_cpu_get and cpufreq_cpu_put, which make sure that the cpufreq driver is correctly registered with the core, and will not be unloaded until cpufreq_put_cpu is called. That also ensures that the respective cpufreq policy doesn’t get freed while being used. 2. CPUFreq notifiers¶
