Hello, I am looking for the amdgpu power knobs. On Linux there is documentation that specifies
allowing me to force the power profile to the lowest possible setting. I want to do this on FreeBSD so I can significantly drop the wattage of a running server.
After some more digging, do the linuxkpi settings:
apply to the amdgpu module that drm-kmod supplies? All documentation indicates this works for the i915 driver, but says nothing about amdgpu.
Code:
$ echo low > /sys/class/drm/card0/device/power_dpm_force_performance_levelallowing me to force the power profile to the lowest possible setting. I want to do this on FreeBSD so I can significantly drop the wattage of a running server.
After some more digging, do the linuxkpi settings:
Code:
compat.linuxkpi.enable_rc6="7" # ENABLE POWER SAVING RENDER C-STATE 6
compat.linuxkpi.enable_dc="2" # ENABLE POWER SAVING DISPLAY C-STATES
compat.linuxkpi.enable_fbc="1" # ENABLE FRAME BUFFER COMPRESSION FOR POWER SAVINGSapply to the amdgpu module that drm-kmod supplies? All documentation indicates this works for the i915 driver, but says nothing about amdgpu.
