What is Processor Hardware Control for Linux?
Processor Hardware Control for Linux (PHC) is an open-source application that provides advanced configuration options for processor hardware on Linux systems. It allows fine-grained control over features such as:
- CPU clock speed and scaling
- Enabling/disabling CPU cores
- Configuring turbo boost and other advanced capabilities
PHC gives administrators and power users more flexibility in tuning system performance. For example, disabling certain CPU cores can help reduce power consumption and heat output. Boosting clock speeds can increase performance in bursty workloads. PHC makes these types of adjustments easier.
Some key capabilities and features of Processor Hardware Control include:
- Simple command line interface and configuration files
- Support for Intel and AMD processors
- Real-time monitoring of CPU temperatures, power consumption, etc.
- Scripting capabilities to automate adjustments
- Integration with external tools like lm-sensors
- Active development community providing support
PHC is licensed under the GPLv3 and works on most modern Linux distributions. It can help optimize Linux systems for performance, power efficiency, or reliability goals.
