Power management daemon for AMD Ryzen Mobile processors.
Power management for AMD Ryzen Mobile processors in Linux is lacking in comparison to Windows. Power and thermal limits are preset conservatively and a possibility to change them is missing which can result in a weak overall system performance when performance is needed and in an increased power usage when mobility is required. ACPI platform profiles are a good solution but in practice they do not always work.
Limits can be adjusted manually with tools like RyzenAdj. However, often the notebook firmware will reset them after a short period of time, and they need to be reapplied again.
To work around this issue, this application periodically sets power and thermal limits and automatically switches profiles when the power source changes, e.g. when switching from AC to battery. All limit settings offered by RyzenAdj are supported.
Additionally, ACPI platform profiles can be controlled by manually writing to the DYTC method, which is useful for kernels with an outdated thinkpad_acpi module.
