Comment # 14
on bug 111987
from Alex Deucher
You can force the clocks low or high by: echo low > power_dpm_force_performance_level or echo high > power_dpm_force_performance_level setting it to auto will restore the automatic behavior: echo auto > power_dpm_force_performance_level The behavior will depend on the workload. If the workload is really bursty, it may cause the clocks to ramp up and down if there are sufficiently long idle periods between workloads. You can manually adjust the heuristics by selecting the custom profile and tweaking each parameter. See the documentation here: https://dri.freedesktop.org/docs/drm/gpu/amdgpu.html#gpu-power-thermal-controls-and-monitoring
