energy_amd

AMD energy monitor — hardware counters via amdsmi (ROCm 6.1+).

Classes

AmdEnergyMonitor 

AmdEnergyMonitor(poll_interval_ms: int = 50)

Bases: EnergyMonitor

AMD GPU energy monitor using amdsmi hardware counters.

Uses amdsmi_get_energy_count() to read per-device energy accumulators. Energy = accumulator_delta * counter_resolution (microjoules), then / 1e6.
