CoreFreq: Introduction to CPU frequency monitoring tool under Linux

In Linux systems, monitoring and managing CPU frequency has always been a relatively important task. By monitoring the frequency of the CPU, we can understand the operating status of the CPU in time and adjust the frequency to improve performance or reduce power consumption. In Linux systems, there are many tools that can be used to monitor CPU frequency, one of the better tools is CoreFreq. This article will introduce the basic functions of the CoreFreq tool and how to install and use it in a Linux system.

CoreFreq Introduction

CoreFreq is an advanced CPU frequency monitoring tool for Intel and AMD processors. It is designed to provide detailed CPU frequency and power consumption information to help users optimize the performance and power of the CPU. Consumption. CoreFreq supports multiple CPU architectures and provides a wealth of functions and parameter options to easily monitor CPU performance and power consumption.

Installing CoreFreq

Installing CoreFreq in a Linux system is very simple and can be installed through package management tools or source code. Here are the steps to install CoreFreq using a package management tool:

1. For Debian-based systems (such as Ubuntu):

sudo apt-get update
sudo apt-get install corefreq

2. For Fedora-based systems:

sudo dnf install corefreq

3. For other distributions, you can compile and install from source code. First download the CoreFreq source code package, and then execute the following commands to compile and install:

tar -zxvf CoreFreq-X.X.X.tar.gz
cd CoreFreq-X.X.X
make
sudo make install

Using CoreFreq

After the installation is complete, you can start CoreFreq through the command line or graphical interface. The following are some commonly used command examples:

1. Start the CoreFreq command line interface:

sudo corefreq-cli

2. Start the CoreFreq graphical interface:

sudo corefreq-gtk

Sample Code

The following is a simple Python script example, using the API provided by CoreFreq to obtain CPU frequency information and print it out:

import corefreq_api

corefreq_api.init()
corefreq_api.enable_event_sampling()
corefreq_api.start_monitor()

for core in corefreq_api.core_list.values():
    print(f"Core {core.core_id}:")
    for freq in core.freq.values():
        print(f"Frequency: {freq.actual/1000} GHz")

corefreq_api.stop_monitor()
corefreq_api.finish()

Through the above code example, we can see how to use CoreFreq API to obtain CPU frequency information and process it.

To summarize, CoreFreq is a powerful CPU frequency monitoring tool under Linux that can help users monitor CPU performance and power consumption. Through the introduction of this article, I believe readers can better understand the basic functions and usage of CoreFreq, so as to better manage and optimize CPU frequency.
