How to use the command auto-cpufreq (with examples)

Auto-cpufreq is a command-line tool that automatically optimizes CPU speed and power consumption. It can monitor CPU performance, update CPU settings, gather statistics, and more.

Use case 1: Run auto-cpufreq in a specific mode

Code:

sudo auto-cpufreq --monitor

Motivation: Running auto-cpufreq in monitor mode allows you to continuously monitor CPU performance and analyze its behavior. This can be helpful to identify any issues or performance bottlenecks.

Explanation:

• sudo: This command is typically used to acquire administrative privileges, which may be required to access and modify CPU settings.
• auto-cpufreq: The name of the command itself.
• --monitor: This mode allows continuous monitoring of CPU performance.

Example output:

Auto-cpufreq monitor mode
-----------------------------------
CPU Frequency: between 2.20 GHz and 4.20 GHz
CPU Governor: performance

Use case 2: Run auto-cpufreq in live mode

Code:

sudo auto-cpufreq --live

Motivation: Using auto-cpufreq in live mode dynamically adjusts CPU settings in real-time based on system workload. This can lead to improved performance and power efficiency.

Explanation:

• --live: This mode enables dynamic adjustment of CPU settings based on workload.

Example output:

Auto-cpufreq live mode
-----------------------------------
CPU Governor: ondemand (adaptive)
CPU Frequency: 1.30 GHz (min), 2.40 GHz (max)

Use case 3: Run auto-cpufreq in update mode

Code:

sudo auto-cpufreq --update

Motivation: The update mode of auto-cpufreq helps you ensure that you have the latest version of the tool installed. It automatically checks for updates and installs them if available.

Explanation:

• --update: This mode checks for updates and installs them if available.

Example output:

Checking for updates...
Auto-cpufreq is up to date (v1.2.0).

Use case 4: Run auto-cpufreq in remove mode

Code:

sudo auto-cpufreq --remove

Motivation: In some cases, you may want to remove auto-cpufreq from your system. The remove mode allows you to uninstall the tool and revert any CPU settings that were modified.

Explanation:

• --remove: This mode uninstalls auto-cpufreq from the system.

Example output:

Removing auto-cpufreq...
Auto-cpufreq has been successfully removed.

Use case 5: Run auto-cpufreq in stats mode

Code:

sudo auto-cpufreq --stats

Motivation: The stats mode of auto-cpufreq provides detailed statistics about the CPU’s performance and behavior. This can be useful for analyzing system performance over time.

Explanation:

• --stats: This mode gathers statistics related to CPU performance and behavior.

Example output:

Auto-cpufreq statistics
-----------------------------------
Total CPU Frequency Boosts: 352
Total CPU Throttles: 14

Use case 6: Run auto-cpufreq in force mode

Code:

sudo auto-cpufreq --force=governor

Motivation: The force mode allows you to manually set the CPU governor to a specific value. This can be useful in situations where you want to override the default governor behavior.

Explanation:

• --force=governor: This mode forcefully sets the CPU governor to the specified value.

Example output:

CPU governor has been set to "performance".

Conclusion:

Auto-cpufreq is a powerful tool for optimizing CPU performance and power consumption. By utilizing its various modes, you can monitor CPU performance, dynamically adjust settings, gather statistics, and more. Experiment with different modes to determine the optimal configuration for your system.
