Linux thermal daemon (thermald) monitors and controls temperature in laptops, tablets PC with the latest Intel sandy bridge and latest Intel CPU releases. Once the system temperature reaches a certain threshold, the Linux daemon activates various cooling methods to try to cool the system.
It operates in two modes:
- Zero Configuration Mode
- For most users, this should be enough to bring the CPU temperature of the system under control. This uses DTS temperature sensor and uses Intel P state driver, Power clamp driver, Running Average Power Limit control and cpufreq as cooling methods.
- User defined configuration mode
- This allows ACPI style configuration in a thermal XML configuration file. This can be used to fix the buggy ACPI configuration or fine tune by adding more sensors and cooling devices. This is a first step in implementing a close loop thermal control in user mode and can be enhanced based on community feedback and suggestions.
How to install
apt-get install thermald
