Sys abstractions
sys/amdgpu¶
AMD's amdgpu driver power management (PowerPlay)
sys/dmi¶
Desktop Management Interface (DMI) firmware tables and identity files
DMI is a standard framework for managing and tracking hardware components in a computer.
Games and game launchers (Steam, Proton, anti-cheat) read these for hardware fingerprinting, telemetry, and compatibility checks. This is the same data from dmidecode but readable without root via sysfs.
sys/gpumon¶
GPU Power/Thermal Controls and Monitoring
