cpufreq-info:tldr:2dff6
The "cpufreq-info" command is used to provide information about the current CPU frequency scaling settings and capabilities of a processor. It is typically used in Linux systems to check and manage the frequency at which the processor operates.
When run, the "cpufreq-info" command displays several details about the CPU frequency scaling, including:
-
Current CPU frequency: It shows the current operating frequency of the processor. This frequency can vary due to the dynamic scaling capabilities of modern processors.
-
Available CPU frequency scaling governors: It lists the available frequency scaling governors supported by the processor. These governors are responsible for determining the CPU frequency based on the system's workload and power requirements.
-
Available CPU frequencies: It provides a list of the different frequencies that the processor can operate at. These frequencies represent the different speed levels that the CPU can reach.
-
CPU frequency scaling driver: It indicates the driver or module responsible for managing the CPU frequency scaling on the system. This information helps in identifying the software component responsible for controlling the CPU frequency.
Overall, the "cpufreq-info" command offers visibility into the CPU frequency scaling behavior, which can aid in troubleshooting performance issues, adjusting power consumption, or obtaining general information about the CPU's capabilities.
